Overview

Fresh Air Unit Functions

The Packaged Fresh Air unit (FAU) provides conditioned outdoor air suitable for mechanical ventilation or make-up air. The FAU conditions outdoor air as necessary to meet system performance requirements by filtration, cooling, dehumidification, and/ or heating. The FAU may deliver ventilation air in a number of ways. See the System Configurations section and

Figures AC-1 through AC-3 for more information.

Filtration

Filtration is necessary for the FAU to maintain system operating efficiency, meet occupant comfort and health needs, and provide adequate building filtration to aid indoor air quality. The

Packaged FAU offers a variety of filter options to meet most application needs.

Cooling

When the outdoor air dry-bulb temperature is warmer than space conditions, the unit cools the outdoor air to the appropriate supply air dry-bulb temperature. The Packaged FAU provides cooling using an air-cooled, directexpansion (DX) refrigeration system with scroll compressors.

Dehumidification (Drying)

The Packaged FAU dehumidifies the outdoor air when it is more humid than the required space target conditions.

This helps prevent high relative humidity levels in the space. Occasionally, the outdoor air may require sub-cooling to remove excess moisture. When necessary, the FAU reheats discharge air to meet space comfort conditions.

The Packaged FAU recovers energy from the cooling process to reheat the sub-cooled air as necessary.

Heating

When the outdoor air dry-bulb temperature is colder than space conditions require, the FAU heats the outdoor air to meet space temperature requirements.

The Packaged FAU has electric or gas heat options available.

System Configurations

Dedicated outdoor air systems can deliver conditioned outdoor air in one of the following ways:

1. Directly to the occupied space, with the local terminal unit controlling the space dry-bulb temperature. See

Figure AC-1.

2. Directly to local terminal units, which deliver a mixture of the conditioned outdoor air and (conditioned) recirculated return air to the space. See

Figure AC-2.

3. Directly to a single space and control the space temperature directly. For example, this application will provide temperature control of a hotel hallway and ventilation of the adjacent rooms.

See Figure AC-3.

Supply Air Temperature

Give careful consideration when selecting the FAU supply air temperature. Many current system designs control the fresh air unit discharge air to a “space neutral” dry-bulb condition, typically about 75°F. At some operating conditions, reheating the FAU supply air will add cooling load to the space, thus requiring the local terminal units to “recool” the conditioned outdoor air to meet the space setpoint. Therefore, to help lower energy costs, use reheat only when required to maintain occupant comfort and space relative humidity. The Capacity Control section discusses this issue in more detail.

Airside Economizers

Often fresh air units are sized to deliver the minimum ventilation air required for the space it serves. However, ventilation air is typically only a portion of the space supply air. Airside economizing can provide up to 100% of the space supply air when outdoor air conditions are suitable for “free cooling” capability.

It’s important to remember that airside economizer capability can be lost if dedicated outdoor air systems are sized for minimum ventilation air only. To provide economizer capability on a dedicated outdoor air system, the terminal units must be able to introduce

100% outdoor air during the economizer-cooling mode. The terminal unit’s outdoor air damper should modulate between fully closed and fully open to allow the FAU to deliver the ventilation air design volume to the space. The terminal unit should enable economizing only if the outdoor dry-bulb and dew point conditions are sufficiently low to justify economizing.

Application

Considerations

Packaged FAU Operation

The Packaged FAU can use either DX cooling, condenser reheat, electric or gas heat to condition the outdoor air.

The unit controls cooling and heating capacity in stages with the exception of the modulated heat options. Cooling and heating staging result in supply air temperature swings. The unit controls deliver the desired supply air conditions on a time-based, weighted average.

FAU with Reheat

Figure AC-4 shows the FAU system with a DX refrigerant circuit design using reheat.

Dehumidification

Consider Chart AC-1. If the outdoor air dew point is above the drying setpoint

(or in the case of zone control, the zone

RH is above the RH setpoint), the FAU will:

• cool the outdoor air to remove required moisture and

• reheat to meet the discharge temperature setpoint.

At h1, 100% outdoor air enters the FAU.

The FAU filters, cools, and dehumidifies the air as it moves through the evaporator coil. Air leaves the evaporator coil saturated at the preset dew point condition (h3) and is reheated by the reheat condenser to the pre-set reheat temperature setpoint (h4). The reheat evaporator transfers energy to the reheat condenser. A liquid solenoid valve effectively modulates the reheat condenser capacity. The reheat outdoor condenser rejects surplus heat. The reheat evaporator circuit is first on and last off, so reheat energy is available at full and part load conditions. For those conditions where the reheat condenser capacity is insufficient to meet reheat demand, optional electric or gas heat can provide additional reheat capacity.

Since both the dew point setpoint and discharge temperature setpoint are fully adjustable, the desired supply air conditions are maintained at all load conditions.

Cooling or Heating

Consider Chart AC-2. If the outdoor air dew point or zone RH is equal to or below the drying setpoint, the FAU will heat or cool the outdoor air to separate and adjust cooling or heating setpoints.

At t1 or t3, 100% outdoor air enters the

FAU. The FAU filters, and cools or heats the air as it is drawn through the evaporators and heating section. The air leaves the FAU at the cooling or heating setpoint (t2 or t4) and equal to or below the dew point setpoint.

Dehumidification (Drying)

Consider Chart AC-3. If the outdoor air dew point or zone RH is above the drying setpoint, the FAU will dehumidify the outdoor air. 100% outdoor air enters the FAU (h1). The unit filters, cools (h2) and dehumidifies the air as it is drawn through the evaporator coils. Air leaves the evaporator coils saturated at a preset dew point setpoint (h3). Since the dew point setpoint is fully adjustable, the desired dew point condition is maintained at all load conditions.

Application

Considerations

Establishing Capacity

Requirements

Determining the FAU capacity requirements requires careful thought. Airhandling equipment is typically selected based on design sensible conditions.

Since latent loads drive the need for the

FAU, base the selection on design latent conditions.

Cooling & Dehumidification

Selection Criteria

Evaporator Design Entering Conditions

For many climates the peak outdoor air enthalpy occurs at a time when the outdoor dry-bulb temperature is not the highest. Refer to the chapter on climatic design information in the ASHRAE

Handbook of Fundamentals. The cooling and dehumidification design condition data is provided three ways:

1. Design dry-bulb temperature with mean coincident wet bulb temperature

2. Design wet-bulb temperature with mean coincident dry-bulb temperature

3. Design dew point temperature with single bank option is 50% and the dual bank is 25%. Calculate the minimum temperature rise to determine the heating control capability. mean coincident dry-bulb temperature

The design wet-bulb condition typically represents a significantly higher outdoor air enthalpy than the design dry-bulb condition. Use the condition that represents the highest enthalpy as the entering evaporator selection condition.

Evaporator Design Leaving Conditions

Due to the uncertainty of the local terminal unit’s latent capacity at part load, it is usually most straightforward to size the FAU to handle the entire latent load on the system, both indoor and outdoor. With this design approach, the terminal units may do some latent cooling (dehumidification) during periods of higher sensible load. At these times, the space will run slightly drier than the design RH limit. This is why it makes sense to select the FAU to limit the space RH to a maximum allowable level for those conditions when the terminal units are providing no space latent cooling. ASHRAE standards 62.1

and 55 recommend using 60% RH design limit for comfort cooling. Using lower design limits may result in an unnecessary increase in system operating energy use.

Use Tables AC-1, AC-2, and AC-3, on pages 9 and 10, to identify the appropriate supply air dew point for specific design conditions. For a more detailed discussion on determining the selection criteria of a FAU, reference Trane publications SYS-EB-3 or SYS-APM-

004.

Reheat

The Trane FAU utilizes recovered energy from the cooling process to reheat the air leaving the cooling coil as required to meet the discharge air setpoint. The reheat refrigerant circuit is adequate to deliver enough reheat to supply space temperature neutral air

(e.g. 75°F dry-bulb) under most operating conditions. On very low load days, the reheat circuit may not contain enough energy to meet the desired reheat setpoint. Under those operating conditions, the FAU can use supplemental heat provided in the heating section.

Because the heat section is sized for the design heating condition, larger than normal supply air temperature swings may occur when using it for incremental reheat energy.

Heating

The FAU has electric or gas heat options. The electric heat option is available in 30-70°F temperature rise offerings with three to seven capacity control stages. This means that the lowest temperature rise provided using one stage depends on heater size, unit airflow, and the number of stages selected. Calculate the temperature rise to confirm that it provides acceptable control. The electric heat will cycle to maintain heating setpoint.

If using hot water heat, install it in the optional rack within the Packaged FAU or in the supply ductwork of the fresh air system. The unit controller will modulate a coil control valve. Provide an ethylene glycol and water mixture or other means of freeze protection for the hot water coil if the FAU will be subject to sub-freezing temperatures.

Capacity Control

The capacity control system on the

Packaged Fresh Air unit is flexible enough to accommodate a variety of system applications. These applications include:

• treating outdoor air to supply a single space or multiple spaces or

• simultaneously meet building makeup air needs while controlling the temperature and relative humidity of a single space.

Each of these applications requires careful consideration to achieve the desired results.

Application

Considerations

Supply Air Control

For many multiple space systems, the

FAU will continuously supply outdoor air at a dry-bulb setpoint and a dew point that does not exceed its dew point setpoint. This control approach is simple because it allows the FAU to function independent of local terminal unit operation or actual space conditions. If the unit selection criteria is determined using the method suggested in the

Establishing Capacity Requirements section, the fresh air unit will limit the space relative humidity to the target level.

When space sensible loads are relatively high, the local terminal unit may perform some latent cooling and drive the space relative humidity level lower than the FAU selection limit. Resetting the supply air dew point from the FAU will offer system operating cost savings.

See the Dew Point Reset section for resetting strategies.

Many fresh air systems supply reheated air directly to terminal units or to spaces that have terminal units performing local sensible cooling. This results in the local terminal units recooling the previously re-heated outdoor air. Resetting the supply air drybulb temperature of the fresh air unit offers the opportunity to minimize the amount of time re-cooling occurs. See the Dry-Bulb Reset section for more information.

Dew Point Reset

The local terminal unit provides sensible control of the space and as a result may coincidentally provide latent cooling to the space. The latent loads in the space can vary, especially if occupant density changes. Since the FAU can provide latent cooling to the space as well, it may be beneficial to reset the FAU supply air dew point to prevent overdehumidifying the space and unnecessarily wasting cooling energy. One way to do this is to place a relative humidity sensor in the space served by the FAU or in a common relief air path (like a return corridor) if the FAU serves multiple spaces. This relative humidity sensor can reset the supply air dew point setpoint of the FAU by responding to actual space latent conditions. The

Packaged FAU offers this control capability.

An alternative dew point control strategy is to reset the leaving dew point of the fresh air unit based on the zone with the highest relative humidity.

The building automation system will determine the zone requiring the driest

(lowest dew point) air and reset the dew point of the air leaving on the FAU accordingly. With this approach, the control and setpoint selection of the fresh air system is dynamically optimized based on actual demand of the controlled space. Comfort and indoor air quality requirements are met while minimizing system energy consumption. A Trane Integrated Comfort TM system can provide this control capability.

Dry-Bulb Reset

Because the Trane FAU dehumidifies the outdoor air by cooling it, this cool outdoor air can reduce the sensible cooling load on the local terminal unit. At low space sensible loads, the cool outdoor air may sub-cool the space, causing the local terminal unit to add heat (new energy heat). Therefore, reset the dry-bulb temperature of the dehumidified outdoor air to minimize space sensible re-cooling so the terminal unit with the lowest sensible load is almost at zero cooling capacity

(within the limit of the dew point setpoint). For chilled water terminal units (such as fan-coils), determine this by monitoring the chilled water valve position. For DX terminal units (such as water-source heat pumps or packaged rooftops), determine by monitoring compressor operation. To take full advantage of space demand based drybulb reset, size the local terminal units based on neutral outdoor air temperature. This strategy will more effectively manage occupant comfort during seasonal changeover for two-pipe terminal unit systems. Because the FAU is not connected to the chiller or boiler plant, accomplish this by resetting the fresh air unit dry-bulb temperature to keep the critical zone at zero heating capacity when the boiler is off and zero cooling capacity when the chiller is off. A

Trane Integrated Comfort™ system can provide this control capability.

Unoccupied Space Humidity Control

The Packaged FAU provides conditioned outdoor air for the ventilation and/or make-up air needs of a building during occupied hours. It can also limit building relative humidity during unoccupied hours. To do this, provide a return air path to the FAU and place a relative humidity sensor in the space served by the FAU or in a common relief air path (like a return corridor) if the FAU serves multiple spaces. The unit will cycle as required to limit the space relative humidity to the unoccupied relative humidity setpoint. Reheat and return air damper options are required for this operation. For dedicated outdoor air systems ducted to terminal units, these units must cycle with the operation of the Packaged FAU.

A Trane Integrated™ Comfort system can provide this control capability.

Space Control

For single space applications, the

Packaged FAU can control space temperature and limit space relative humidity. To do this, size the airflow to meet whichever is the highest: the space loads and ventilation and/or make-up air needs of the application.

Install a temperature sensor in the space to provide temperature control and reset the supply air temperature. If reset of the supply air dew point is desired, install a space relative humidity sensor in the space to provide relative humidity limit control.

Outdoor Airflow Balancing

Establish final unit airflow through a field air balancing procedure. Change the fan speed through replacement or fan sheave adjustment.

To simplify this procedure, optional

Traq TM outdoor airflow measuring dampers are available for continuous airflow sensing feedback. The dampers monitor the outdoor airflow intake and can help validate and troubleshoot system airflow issues. Do not use them for building pressure control.

Application

Considerations

Air to Air Energy Recovery

Energy recovery can significantly reduce HVAC system first-cost and operating energy costs. You can use recovered energy for two purposes:

1. to temper or reheat supply air for independent control of sensible and latent capacity, or

2. to precondition outdoor air as it enters the building for ventilation.

The Packaged FAU offers refrigerant heat recovery for reheating the supply air. To precondition the outdoor air, use the total energy wheel option to recover energy from building exhaust.

Controlling an Energy Recovery

Ventilator

One way to control an energy recovery device is to turn it on and off with the

FAU system exhaust fan. In this case, the total energy wheel enables when the unit is in occupied mode and the exhaust fan is running. While this control method is certainly simple and effective in some applications, it may not provide the expected energy saving benefit, particularly when cold air (vs. neutral air) is supplied to the building.

Another more effective approach is to use the outdoor air dry-bulb to determine when to energize or de-energize the energy recovery device. See Figure

AC-7 for an example of this simplified version of energy recovery. In addition to being more effective from a control standpoint, it’s also a very simple control method because the total energy wheel (only) enables when all of the following are true:

• unit is in occupied mode

• exhaust fan is enabled

• outside air temperature is above the upper limit setpoint (default setpoint

80°F) or below the lower limit setpoint

(default setpoint 45°F)

• outside air temperature is above the frost protection setpoint (default setpoint 12°F).

Set the upper limit setpoint to the anticipated return air dry-bulb temperature. Set the lower limit setpoint to 10°F less than the supply air dry-bulb setpoint. This control strategy prevents the energy recovery device from potentially adding to the load seen by the cooling and/or heating system of the unit, but rather utilizing the device only at those times when it provides true operating energy savings.

If using the FAU to deliver cold, dry conditioned air to the building (outdoor air is cooled to a low dew point but not reheated), use the dry-bulb control option.

Cross Leakage

All energy wheels have some cross leakage. Therefore, do not use energy wheels in applications involving toxic or hazaradous air streams. The percentage of cross leakage depends on the pressure differentials across the wheel section. With Trane Packaged FAU energy wheels, the exhaust air transfer ratios are typically low (<4%).

Considerations

Drain Pan Trapping

FAU units are selected based on dehumidification capability. As such, condensate can form at an enormous rate. Therefore, the Packaged FAU drain pan and condensate line are sized and designed accordingly. However, an often-overlooked element of proper condensate drainage is trapping. An incorrectly designed and installed trap on the piping exiting the drain pan can restrict condensate flow or cause condensate to ‘‘spit’’ or “geyser.” This can dampen the air handler interior and/ or ductwork, creating an opportunity for mold infestation. Carefully install and trap the drain pan to ensure adequate condensate removal under all conditons. See Figure AC-8 for the proper p-trap design for the drain pan.

H = (1’’ for each 1’’ of maximum negative static pressure) + 1’’

J = half of H

L = H + J+ pipe diameter + insulation

Acoustical Considerations

Proper unit placement is critical to reducing transmitted sound levels from the FAU to the building. Therefore, consider acoustic concerns during the design phase and place the unit accordingly. The most economical means of avoiding an acoustical problem is to place the unit(s) away from acoustically critical areas. If possible, do not locate units directly above areas such as: offices, conference rooms, executive office areas, and classrooms. Instead, ideal locations to consider are: over corridors, utility rooms, toilets, or other areas where higher sound levels directly below the unit(s) are acceptable.

Follow these basic guidelines for unit placement to minimize sound transmission through the building structure.

1. Never cantilever the compressor side of the unit. A structural cross member must support this side of the unit.

2. Locate the unit’s center of gravity close to or over column or main support beam.

3. If the roof structure is very light, replace roof joists by a structural shape in the critical areas described above.

4. If several units are to be placed on one span, stagger them to reduce deflection over that span.

It is impossible to totally quantify the building structure effect on sound transmission because it is dependent on how the roof and building members respond to the FAU ’s sound and vibration. However, following the guidelines listed above will help reduce sound transmissions.

Clearance Requirements

Follow the recommended unit clearances to assure adequate serviceability, maximum capacity, and peak operating efficiency. Reducing unit clearances may result in condenser coil starvation or warm condenser air recirculation. If the recommended clearances are not possible on a particular job, consider the following:

• Do the clearances available allow for major service work, such as changing compressors or coils?

• Do the clearances available allow for proper outside air intake, exhaust air removal, and condenser airflow?

• If screening around the unit is used, is there a possibility of air recirculation from the exhaust to the outside air intake or from condenser exhaust to condenser intake.

Review any actual clearances that appear inadequate with your local

Trane sales engineer.

When two or more units are placed side by side, increase the distance between the units to 150% of the recommended single unit clearance. Stagger the units for these two reasons:

1.To reduce span deflection if more than one unit is placed on a single span.

Reducing deflection discourages sound transmission.

2.To assure proper exhaust air diffusion before contact with the adjacent unit’s outside air intake.

Duct Design

It is important to note that the rated capacities of the FAU can be met only if the unit is properly installed. A welldesigned duct system is essential to meet these capacities.

Satisfactory air distribution throughout the system requires an unrestricted and uniform airflow from the rooftop discharge duct.

However, when job conditions dictate installation of elbows near the FAU outlet, using guide vanes may reduce capacity and static pressure loss.

Selection

Procedure

FAU Selection Procedure

Prior to selecting the fresh air unit (FAU) for a given application, give careful consideration to determining the design latent conditions (as described in the

Applications Considerations section of this catalog). Use Tables AC-1, AC-2, and AC-3 on pages 9 and 10 to identify the appropriate supply air dew point for specific design conditions. See SYS-

APG001-EN or SYS-APM-004 for more detailed information.

Selection of Trane Packaged Fresh Air units is divided into five basic areas:

1. cooling/dehumidification capacity

2. air delivery

3. heating capacity

4. unit electrical requirements

5. unit designation

Factors used in unit cooling/dehumidification (drying) selection:

Example

Example unit options include:

• parallel blade OA damper

• 2” pleated media filters

• gas heat – hi rise, single bank, 2-stage

• fan type 12-9

Given conditions:

• airflow required for proper ventilation

(per ASHRAE 62) = 2300 cfm

• outside air summer design conditions

= 95°db/78°wb, 95°F entering air to condenser

• supply air design dew point requirement = 53°F dew point

• total peak cooling load = 198 MBh (16.5

tons)

• total peak dehumidification load = 90

MBh (7.5 tons)

• condenser reheat provided (yes or no)

= for this example, reheat is installed

• external static pressure = 0.5 inches

• desired supply air db temp. = 75°F

Step 1 – Determine unit size.

To determine which unit size will meet your capacity requirements, first review the airflow ranges found in Table GD-1 on page 21. The specified airflow in this example of 2300 cfm falls in both the size 031 and 040 unit airflow ranges.

Step 2 – Determine SA dew point capability.

Check the smaller unit size first to determine if it has the capacity to meet the supply air dew point and cooling/ dehumidification requirements. See

Table PD-31 to review the supply air dew point vs. airflow range that the size

031 unit can provide. At 95°db/78°wb, the size 031 produces 53°F dew point supply air at 2301 cfm (value found by interpolating between the 52°F and

54°F dew point data provided in the table). Therefore, the size 031 unit meets the supply air dew point requirement.

Step 3 – Determine unit capacity.

Now check that the size 031 unit meets the cooling and dehumidification capacity requirements by reviewing

Table PD-28. At 2300 cfm and 95°F db/

78°F wb, the size 031 unit produces

201.42 MBh total and 92.68 MBh latent capacity. This meets our requirement.

Also note that Table PD-27 provides information very similar to that in Table

PD-28. Use Table PD-27 (and tables like it for all other units sizes) only when condenser reheat is not provided. For this example, we will include condenser reheat.

Step 4 – Determine supply air fan data.

First calculate size 031 unit total static pressure (tsp) at design supply cfm using the appropriate air pressure drop tables. See calculation below: external static pressure = 0.50‘’ parallel blade OA damper = 0.01’’

2” pleated media filter = 0.08’’ main evap coil (wet) = 0.37’’ reheat evap coil (wet) = condenser reheat coil = gas heat exchanger =

0.19’’

0.15’’

0.37’’ unit total static pressure = 1.67’’

Using 2300 cfm and tsp of 1.67 inches, refer to Table PD-1, which shows 1017 rpm and 1.06 bhp at 1.6 tsp. Interpolate the values from the table (between 1.60

and 1.80 tsp), and calculate 1058 rpm and 1.077 bhp at 1.67 tsp.

Step 5 – Determine supply air temperature.

If the unit does not have condenser reheat, the supply air db is equal to the supply air dew point (53°F). However, for this example, condenser reheat is required, and a supply air db temperature of 75°F is desired. Go to Table PD-

30 on page 49 to determine the supply air db temperature produced by the size

031 unit. At 2300 cfm and 95°F db/78°F

17

Selection

Procedure db, the size 031 unit produces condenser reheat max temp rise of 24.9°F.

Now calculate the fan motor heat temp rise for this selection. Go to Figure SP-1 to determine that 1.077 bhp = 3.269

MBh. Supply fan motor heat temp rise =

3269 btu/(1.085 x 2300 cfm) = 1.3°F.

Calculate supply air db temp by summing the off-coil supply air db with the condenser reheat maximum temperature rise and the motor heat temperature rise at the design condition:

Supply air db temperature:

53°F + 24.9°F + 1.3°F = 79.2°F

Thus, the size 031 unit has the capability to meet and slightly exceed the supply air db temperature requirement of 75°F.

So, for this example, the size 031 unit meets all requirements with a supply air temperature of 79.2°F db/63.1°F wb with a 53°F supply air dew point.

However, if the supply air temp setpoint at the unit controller is set to 75°F, the unit will modulate the condenser reheat to meet that supply air condition versus exceed it. Also note that Table PD-30 provides reheat max temp rise data for typical design and part load conditions.

This enables you to determine if the condenser reheat is sufficient to maintain comfort during typical part load conditions.

Heating Capacity Selection

Example

Given conditions:

• winter outdoor design conditions = 0°F

• heat type = gas

• max temp rise or heating kW/MBh requirement = 80°F temperature rise

To select a single bank gas heater as specified, go to Table PD-73 for the size

031 unit. At 2300 cfm, a 250 MBh gas heater will produce an 80°F temperature rise. Select this heater.

If your application requires electric heat, use the electric heat tables on pages 73 through 74.

Air Delivery Procedure

Supply Air Fan Selection

Unit supply air fan performance tables include pressure drops for internal cabinet static losses. Add static pressure drops of optional components such as heat and filters to the external duct static pressure to determine the total static pressure.

The supply requirements determined in

Step 4 of the cooling/dehumidification capacity example was 1.077 bhp at

1058 rpm. Thus, the supply fan motor size required is two hp at 1075 rpm.

Unit Electrical Requirements

To determine electrical requirements for wire sizing amps and maximum over-current protection, see in the

Electrical Data section on pages 86–89.

Unit Designation

After determining specific unit capacity requirements and considering specific job requirements, determine the complete unit model number by referencing pages 14–16.

Procedure

Fresh Air Unit with Total

Energy Wheel

Common Terms

Following are definitions of common terms used when selecting a fresh air unit with a total energy wheel.For more information on this subject, reference

Trane application manual, Air-to-Air

Energy Recovery in HVAC Systems,

SYS-APM003-EN.

EATR - exhaust air transfer rate expressed as a percentage, is the tracer gas concentration difference between the outdoor airflow entering the total energy wheel and the supply airflow leaving the wheel divided by the tracer gas concentration difference between the exhaust airflow entering the total energy wheel and the outdoor airflow entering the wheel.

OACF - The outside air correction factor is defined as the supply-side airflow upstream of the wheel divided by the supply-side airflow downstream of the wheel. This value is important for sizing the fans. Also, if the system includes an airflow monitoring station or flowmeasuring damper, it allows for the set point of this device to compensate and assure that the proper amount of outdoor air flows into the wheel so that the required amount of outdoor air leaves the wheel. The OACF is typically small unless the pressure difference between the air streams is greater then

3.0 in H2O.

The term effectiveness is used to describe the heat transfer efficiency of an air-to-air heat exchanger. Effectiveness is defined as the actual energy

(sensible, latent, or total) transferred by

MUA-PRC004-EN the device, divided by the maximum possible energy transfer between the two air streams. If the effectiveness of the device were 100% the condition of the air leaving the supply-side of the device would be the same as the condition of the air entering the exhaust-side of the device.

In addition to understanding the wheel performance terms, consideration should be given to airflow performance in applications with a total energy wheel. The terms below explain the air paths through the total energy wheel and should all be considered when selecting an energy recovery device.

Entering exhaust airflow represents the exhaust airflow exiting the building prior to passing through the total energy wheel.

Leaving exhaust airflow represents the exhaust airflow after passing through the total energy wheel.

Net exhaust airflow represents the portion of leaving exhaust airflow that originated as entering exhaust airflow.

Leaving supply airflow represents the sum of the net supply airflow and the additional air picked up in the airstream while passing through the total energy wheel (difference between entering and net exhaust airflow).

Outdoor airflow represents the amount of outdoor air entering the unit.

Net supply airflow represents that portion of the leaving supply airflow that originated as outdoor airflow

(equal to 1 - EATR.

Note:

EA/OA is the ratio of net exhaust airflow to net supply airflow (expressed as a percentage).

Selection Example

Given:

4000 cfm, 100% EA/OA, 95/78°F OA conditions, 72/60°F (52 dewpoint) SA conditions, 1” WC supply ESP, 1” WC exhaust ESP, 75/63°F summer RA conditions, 70F/30% RH winter RA conditions

Step 1 - Determine unit size.

To determine which unit size will meet your capacity requirements, first review the airflow ranges found in Table GD-1.

The specified airflow in this example of

4000 falls into unit sizes 040, 051, and

066 airflow ranges.

Step 2 - Determine SA dewpoint capability.

Check the smaller unit size first to determine if it has the capacity to meet the supply air dewpoint requirements.

See Table PD-56 on page 63 to review the supply air dewpoint vs. airflow range that the size 040 unit can provide.

At 95/78°F, the size 040 unit has the capacity at 4000 cfm to provide a 51 DP or higher. Therefore, the size 040 unit meets the supply air dewpoint requirement.

Step 3 - Determine unit and wheel capacity.

The 040 unit with a total energy wheel data can be pulled directly of the unit capacity Tables PD-53 and PD- 54 on pages 62-63:

The 040 unit with a total energy wheel produces 391 MBh total capacity and

155 MBh latent capacity.

The 040 wheel only capacity is 152 MBh total and 92 MBh latent.

Step 4 - Determine exhaust airflow and actual amount of OA supplied to the space.

Use the APD lookup tables to find P2 and P3 below for the 040 unit at 4000 cfm:

Find P2 = energy module OA filters + energy wheel and module (use Table

PD-13)

P2 = 0.23 + 1.34 = 1.57

Find P3 = energy module EA filters + return ESP, using Table PD-13 on page

34:

P3 = 0.23 + 1 = 1.23

2P3 = 1.57 - 1.23 = 0.34

Find EATR and OACF using 2P3 from

Table SP-1:

EATR = 4.0%

OACF = 1.05

Calculate net OA: netOA = SA(1-EATR) netOA = 4000*(1- 0.04) = 3840 cfm

19

Selection

Procedure

Step 5 - Determine supply fan data.

First calculate unit total static pressure at design cfm of 4000 using the appropriate air pressure drop tables. See calculation below: external static pressure = 1.00” energy wheel OA filters = 0.23” energy wheel & module = 1.34”

OA dampers (Traq) = 0.28” reheat evap coil (wet) = 0.31” main evap coil (wet) = 0.62” condenser reheat coil = 0.24” unit total static pressure = 4.02”

Use SA and TSP with the fan curve/ table to determine the supply fan’s operating point.

12-9 FC, 1686 rpm, 5.19 hp

15-11 FC, 1330 rpm, 4.39 hp

Select 15-11 FC, 1350 rpm and 5 hp motor.

Step 6 - Determine exhaust fan data.

EA = SA[OACF + EATR -1 + (1 -

EATR)[net EA/net OA]] net EA = net OA [net EA/net OA]

EA = 4000*(1.05 + 0.04 - 1 + (1 -

0.04)*1.0) = 4200 cfm

NetEA = 3840*0.8 = 3072 cfm

Use EA and P3 with the 040 exhaust fan curve/tables, Chart PD-6 and Table PD-6 on page 27, to determine the exhaust fan’s operating point.

1763 rpm, 5.07 hp

Select 1775 rpm, 7.5 hp

Step 7 - Determine supply air temperature.

The 040 unit with evap coils plus the total energy wheel produce a supply air db of 51°F.

The 040 unit plus wheel produces a reheat rise of 19.8°F. See the size 040 unit/wheel reheat temp rise Table PD-55 on page 63.

Motor temp rise is X (for instructions on calculating motor heat temp rise, review step 5 under FAU selection procedure for unit without total energy wheel).

Supply air temp = 51 + 19.8 + X = 70.8 +

X

Step 8 - Determine wheel frost setpoint.

Find the point on the frost threshold curve (Table SP-2) that intersects with your RA winter relative humidity. Then read the associated OA dry-bulb temperature. The frost threshold chart assumes winter RA dry-bulb or 70°F.

For other conditions, use the TOPSS selection program.

Controls

Packaged Fresh Air Unit

with

Controls

The Intelligent Air-Cooled Chillers

We have designed the Trane Packaged

Fresh Air unit with the latest control technology. Modular DDC controls with human interface (HI) panel make

Packaged Fresh Air units flexible and easy to operate.

Controls are Trane-designed to work with Trane equipment for optimum efficiency. The factory installs and commissions each control component to ensure simple and reliable operation.

Furthermore, the DDC control’s modular design allows greater application flexibility using up to twelve different modules, dependent upon unit options.

You can order exactly what the job requires as options, instead of one large control package. And since unit features are distributed among multiple printed circuit boards, field replacement is easy.

Depending on unit options, IntelliPak™ units can operate as:

1) stand-alone

2) interface with Trane’s Tracer Summit™ building management system

3) interface with a generic (non-Trane) building management system (via

LCI-I using LonTalk ® DAC profile).

4) interface with a generic hard-wired

(non-Trane) building management system via analog input and binary output interface board (GBAS)

Standard IntelliPak Unit Control

Features

All set-up parameters are preset from the factory, requiring less startup time during installation.

The human interface panel is easy to read and requires less time for building maintenance personnel to learn to interact with the unit. It features a clear language display (in English, Spanish, or

French) that shows all of the Packaged

Fresh Air unit control parameters, including system on/off, demand limiting type, night setback setpoints, and many other setpoints. All adjustments are done through the human interface keypad. Also, the human interface panel allows you to monitor diagnostic points such as sensor failures, supply airflow loss, and inoperative refrigerant circuit.

No special tools are required for servicing the unit. Diagnostics are held in memory, even during power loss.

This allows the operator/servicer to diagnose the failure root cause.

IntelliPak Unit Features

• Unit mounted human interface panel with a two line x 40 character display in English, Spanish, or French language and a 16-function keypad that includes CUSTOM, DIAGNOSTICS, and SERVICE TEST MODE menu keys

• Frostat™ coil frost protection on all units

• Supply air or zone dehumidification control

• Supply air or zone temperature control

• Efficient condenser hot gas reheat with modulating capacity (optional)

• Morning warmup operation

• unoccupied airside economizer

77

Controls

(optional) when unit has return air damper option

• supply airflow proving

• supply air tempering control with heating option

• mappable sensors and setpoint sources

• occupied/unoccupied switching

• timed override activation

Human Interface Panel (HI)

The human interface panel provides a

16-button keypad for monitoring, setting, editing and controlling. The HI panel is mounted in the unit’s main control panel, accessible through the unit’s control panel door.

The optional remote-mount version of the human interface (RHI) panel has all the functions of the unit-mounted version, except for the service mode. To use a RHI, the unit must be equipped with the remote HI interface option, which includes an interprocessor communications bridge (IPCB). The RHI can be located up to 1,000 feet (304.8

m) from the unit. A single RHI can be used to monitor and control up to four fresh air units, that have each been supplied with a RHI interface option

(IPCB module).

The main menus of the human interface panels are:

• STATUS monitors temperature, pressure, humidity, setpoints, and input and output status.

• CUSTOM key allows the user to customize a status report - consisting of up to four screens of the data available in the main Status menu.

• SETPOINT allows the user to edit all factory preset default setpoints.

Control Sequences of

Operation

Morning Warmup

This feature is available on all types of factory-installed heat units and on units with no heat. This function may still be selected to support systems with heat sources not provided by the fresh air unit. At the conclusion of unoccupied mode, the selected zone is heated to the user-defined morning warmup setpoint.

The unit is then released to occupied mode. There are two types of morning warmup: full capacity or cycling capacity.

• Full capacity morning warmup (MWU)

Full capacity morning warmup uses full heating capacity to heat the zone as quickly as possible. Full heating capacity is provided until the morning warmup setpoint is met. At this point, the unit is released to daytime mode.

• Cycling capacity morning warmup

(MWU)

Cycling capacity morning warmup provides gradual heating to overcome

“building sink” as the zone is heated.

Normal zone temperature control with varying capacity raises the zone temperature to the MWU zone temperature setpoint. Cycling capacity

MWU will operate until MWU setpoint is reached or for 60 minutes. Then the unit switches to occupied mode. Cooling will suspend until building load conditions exceed the MWU setpoint of 3°F (1.7°C), which is field adjustable.

Ventilation Override (VOM) Option

The user can customize up to five different override sequences for purposes of ventilation override control.

If more than one VOM sequence is requested, the sequence with the highest priority initiates first. Priority schedule is that sequence “A” (unit off) is first, with sequence “E” (purge sequence) last.

• UNIT OFF sequence “A”

When complete system shut down is required, the following sequence is used.

• supply fan – off

• outside air dampers – closed

• heat – all stages – off, modulating heat output at 0 vdc

• occupied/unoccupied output – deenergized

• VO relay –energized

• exhaust fan (field-installed) – off

• exhaust damper (field-installed) – closed

• PRESSURIZE sequence “B”

This override sequence is for use when a positively pressured space is desired instead of a negatively pressurized space.

• supply fan – on

• outside air dampers – open


• occupied/ unoccupied output – energized

• VO relay – energized

• exhaust fan (field-installed) – Off

• exhaust damper (field-installed) – closed

• EXHAUST sequence “C”

With the building’s exhaust fans running and the unit’s supply fan off, the conditioned space becomes negatively pressurized. This is desirable for clearing the area of smoke when necessary (i.e., from an extinguished fire, to keep smoke out of areas that were not damaged).

• supply fan – off

• outside air dampers – closed

• supply fan on

• outside air damper – open

• heat: all stages off, modulating heat output at 0 vdc

• occupied/unoccupied output energized

Note: Each system (cooling, exhaust, supply air, etc.) within the unit can be redefined in the field for each of the five sequences, if required. Also the definitions of any or all of the five sequences may be locked into the software by simple key strokes at the human interface panel.

Generic Building Automation System

Module (GBAS) Option

The generic building automation system module (GBAS) provides broad control capabilities for building automation systems other than a Tracer Summit system. Use a field provided potentiometer or a 0-5 vdc signal to any of the

GBAS inputs, to access the following inputs and outputs listed in the paragraphs below.

• GBAS analog inputs

These four analog inputs can be configured to any of the following:

(1) occupied zone cooling

(2) unoccupied zone cooling

(3) uccupied zone heating

(4) unoccupied zone heating

(5) SA cooling setpoint

(6) SA heating setpoint

(7) space static pressure setpoint

(8) SA static pressure setpoint

• GBAS binary outputs

Each of the five (5) relay outputs can be mapped to any/all of the available diagnostics.

• Demand limiting binary input

This function is operational on units with a GBAS and reduces electrical consumption at peak load times. There are two types of demand limiting, 50% and

100%. When demand limiting is needed, mechanical cooling and heating operation are either partially (50%), or completely disabled (100%) to save energy. The demand limit definition is user definable at the human interface panel. Demand limit binary input accepts a field supplied switch or contact closure. When the need for demand limiting discontinues, the unit’s cooling/heating functions will (again) fully enable.

Evaporator Coil Frost Protection

Frostat™

A temperature sensor on the evaporator determines if the coil is getting close to a freezing condition. Mechanical cooling capacity is shed as necessary to prevent icing.

The Frostat™ system eliminates the need for hot gas bypass and adds a suction line surface temperature sensor mounted near the TXV bulb location to shut off cooling when coil frosting conditions occur. The supply fan does not shut off and will de-ice the coil.

Timers prevent the compressors from rapid cycling.

Occupied/Unoccupied Switching

There are four ways to switch occupied/ unoccupied:

(1) programmable night setback sensor

(2) field-supplied contact closure

(hardwired binary input to RTM)

(3) Tracer Summit or other BAS (via LCI with LonTalk DAC profile)

(4) factory-mounted time clock

• Field supplied occupied/unoccupied input on the RTM

This input accepts a field supplied switch or contacts closure such as a time clock.

• Tracer system

The Tracer system can control the occupied/unoccupied status of the fresh air unit.

• Factory mounted time cock

A time clock can control the occupied/unoccupied status of the fresh air unit.

Timed Override Activation - ICS

This function is operational whenever the unit’s RTM module board is used as the zone temperature sensor source, which can be set at the human interface panel. Initiate this function by pressing the override button on the zone sensor, to switch the unit to the occupied mode.

Unit operation (occupied mode) during timed override will terminate by a signal from Tracer.

Timed Override Activation - Non-ICS

This function is active whenever the user selects the unit’s RTM module board as the zone temperature source

(can be set at the human interface panel). Initiate this function by pressing the override button on the zone sensor, which will switch the unit to the occupied mode. Automatic cancellation of the timed override mode occurs after three hours of operation.

Low Ambient Compressor Lockout

This function will lock out the compressor if the outdoor air temperature is below the low ambient compressor lock-out temperature setpoint when using a field-installed outside air sensor.

This setpoint is adjustable at the human interface panel. Compressors will lock

Operation out when outdoor air temperature falls below that selected temperature and will start again when the temperature rises 5°F above the setpoint.

Comparative Enthalpy Control of

Unoccupied Economizer Operation

An optional comparative enthalpy system controls the economizer operation and measures the temperature and humidity of both return air and outside air to determine which source has lower enthalpy. This system allows true comparison of outdoor air and return air enthalpy by measurement of outdoor and return air temperature and humidity. The comparative enthalpy option should always be ordered with a return air damper.

Note: If the unit does not have comparative enthalpy, the Packaged Fresh Air unit compares outdoor air enthalpy with a fixed reference enthalpy, set through the human interface panel. If ordering the reference enthalpy option, you should also order a return air damper.

Also, either supply air dehumidification with zone RH reference or zone dehumidification with OA RH reference must be ordered to utilize either comparative enthalpy or reference enthalpy control.

Emergency Stop Input

A binary input is provided on the unit’s

RTM module board for installation of a field-provided switch or contacts to immediately shutdown all unit functions.

Total Energy Wheel with Occupancy

Control

The optional total energy wheel recovers energy from the exhaust airstream and preconditions the outdoor air. The total energy wheel enables when the unit is in occupied mode and the exhaust fan is running.

The wheel disables during unoccupied mode or any time that the exhaust fan is not running. This includes the unoccupied economizer mode when the wheel disables, but the exhaust fan enables.

The wheel also disables via a factoryinstalled thermostat at any time a frost condition occurs (default setpoint 12°F).

This frost protection thermostat utilizes a setpoint range of -30 to 100°F.

Total Energy Wheel with Dry-Bulb

Control

The optional total energy wheel recovers energy from the exhaust airstream and preconditions the outdoor air. The total energy wheel enables when all of the following are true:

• unit is in occupied mode

• exhaust fan is enabled

• outside air temperature is above the upper limit setpoint (default setpoint

80°F) or below the lower limit setpoint

(default setpoint 45°F)

• outside air temperature is above the frost protection setpoint (default setpoint 12°F)

Always set the upper limit setpoint to the anticipated return air dry-bulb temperature. Set the lower limit setpoint to 10°F less than the unit supply air dry-bulb setpoint. The wheel will disable during unoccupied mode or when the exhaust fan is not running.

This includes the unoccupied economizer mode when the wheel will disable, but the exhaust fan will enable.

The wheel also disables via a factory installed thermostat when a frost condition occurs. This frost protection thermostat utilizes a setpoint range of

-30 to 100°F.

Electrical

Data

Power Wire Sizing and

Protection Device

Equations

Each type of unit has its own set of calculations for MCA (minimum circuit ampacity) and MOP (maximum overcurrent protection. For units with multiple modes of operation, you must consider each individual field-wired hazardous voltage circuit. Use the load that provides the highest value in the applicable circuit. To correctly size the unit’s electrical service wiring, read the load definitions that follow and then find the appropriate set of calculations based on your unit type.

Load Definitions

Load 1 = current of the largest motor

(compressor or fan motor)

Load 2 = sum of the currents of all remaining motors

Load 3 = current of electric heaters

Load 4 = control power transformer

= any other load rated at one amp or more (gas heat, factory-wired convenience outlet)

Set #1: Cooling Only Units and Cooling with Gas Heat, All Single Source Power

MCA = (1.25 x load 1) + load 2 + load 4

MOP = (2.25 x load 1) + load 2 + load 4

Select an overcurrent protective device rating equal to the MOP value. If the

MOP value does not equal a standard device size as listed in NEC 240-6, select the next lower standard device rating. If the selected MOP is less than the MCA, then reselect the lowest standard maximum overcurrent protective device size that is equal to or larger than the MCA, provided the reselected device size does not exceed 800 amps.

Disconnect Switch Sizing (DSS) – if field provided and installed

If the unit has a factory-installed, nonfused disconnect switch, this sizing equation is not necessary. If the disconnect is field-provided and installed, use the following equation to determine its rating:

DSS = 1.15 x (load 1 + load 2 + load 4)

Select a disconnect switch (DSS) size equal to or larger than the DSS value calculated.

86

Set #2: Units with Electric Heat, Single

Source Power, Non-Concurrent Load

To arrive at the correct MCA and MOP values, you must perform two sets of calculations: one for cooling only (set #1) and one for electric heat only (set #2).

Calculate the MCA and MOP values as if the unit were in the cooling mode (use the equations given in set #1). Then repeat the calculations for MCA and

MOP for the unit in the heating mode using set #2. When determining loads, keep in mind that the compressors and condenser fans do not run while the unit is in the heating mode.

For units using heaters:

• less than 50 kW, use the formula,

MCA = 1.25 x (load 1 + load 2 + load 4)

+ (1.25 x load 3)

• equal to or greater than 50 kW, use

the formula, MCA = 1.25 x (load 1 + load 2 + load 4) + load 3

Select the nameplate MCA value that is the larger of the cooling (set #1) or the heating mode MCA calculated above.

MOP = (2.25 x load 1) + load 2 + load 3 + load 4


MOP value does not equal a standard device size as listed in NEC 240-6, select the next lower standard device rating. If the next lower standard rating is less than 125% of the current rating of the electric heater load, select the next higher standard device rating. If the selected MOP is less than the MCA, then reselect the lowest standard device size which is equal to or larger than the

MCA, provided the reselected device size does not exceed 800 amps.

Select the MOP value that is the larger of the cooling (set #1) mode MOP value or the heating MOP value calculated above.


If the unit is ordered with a factoryinstalled non-fused disconnect switch, this sizing equation is not necessary. If the disconnect is to be field-provided and installed, use the following equation to determine its rating:

DSS = 1.15 x (load 1 + load 2 + load 3 + load 4)

Select the DSS value that is the larger of the cooling (set #1) mode DSS or the heating mode DSS value calculated above. Select a disconnect switch size equal to or greater than the DSS value calculated.

Set #3: Units with Electric Heat, Single

Source Power, Concurrent Load

Concurrent load = 2 compressors and first stage electric heat

Primary Heat Reheat Selection

You may enable primary heat reheat to take advantage of the primary heat source as supplemental reheat for the condenser reheat. Although in most cases, the MCA and MOP values are unaffected by the concurrent loads of compressors, condenser fans, and first stage of electric heat, there are a few circumstances where the MCA and

MOP are increased when this sequence is employed.

You must perform three sets of calculations to obtain the correct MCA and

MOP values: one for cooling (set #1) only, one for electric heat (set #2) only, and one for when the unit is in the cooling mode with compressors and electric heat on concurrently (set #3).

For size 031 and 040 units, compressors

A (1K1) and B (1K2) can run concurrently with 1 /

3

of three-stage electric heat or 1 /

7

of seven-stage electric heat.

For size 051 and 066 size units, compressors A (1K1) and D (1K4) can run concurrently with 1 /

3

of three-stage electric heat or 1 /

7

of seven-stage electric heat.

For units using heaters less than 50 kW:

MCA = (1.25 x load 1) + load 2 + load 4 +

(1.25 x load 3)

For unit using heaters equal to or greater than 50 kW:

MCA = (1.25 X load 1) + load 2 + load 3 + load 4

Select the nameplate MCA value that is the largest of the three sets of MCA calculations.

MOP = (2.25 x load 1) + load 2 + load 3 + load 4


MOP value does not equal a standard device size as listed in NEC 240-6, select

Data the next lower standard device rating. If the next lower standard rating is less than 125% of the current rating of the electric heater load, select the next higher standard device rating. If the selected MOP is less than the MCA, then reselect the lowest standard device size which is equal to or larger than the

MCA, provided the reselected device size does not exceed 800 amps.

The MOP value selected should be the largest of the three sets of MOP value calculations.



DSS = 1.15 x (load 1 + load 2 + load 3 + load 4)

For the calculations of MCA1 and MOP1, use the instructions from set #1 previously in this section.

MCA2 and MOP2 represent the values calculated for the operation of the unit in heating mode:

Specifications

Fan Motors

The supply and exhast fan motors are either standard-efficiency open dripproof or high-efficiency open drip-proof.

All supply fan motors meet the U.S.

Energy Policy Act of 1992 (EPACT).

Exhaust Backdraft Damper

A backdraft damper prevents outside air entry into the building through the exhaust fan. Damper frame is extruded aluminum with mitered corners. Blades are formed aluminum with extruded vinyl edge seals that mechanically lock into the blade edge. Bearings are corrosion resistant synthetic and the linkage is concealed in frame for low pressure drop and noise.

Condenser Fan and Motors

The unit condenser fans are vertical discharge, direct-drive fans. They are statically and dynamically balanced. The blades and spider are constructed of zinc-plated steel. Condenser fan motors are three-phase motors with permanently lubricated ball bearings, built-in current and thermal overload protection, and weather-tight slingers over the motor bearings.

Filters

The filter racks (see Figure MS-4) accommodate 2” filter media and are field convertible to allow 4” filter media.

Figure MS-4. Filter racks

112

Dampers – Low Leak

The outside air damper has a unitcontrolled actuator with parallel-blades.

The blade construction is a 14-gage galvanized steel, roll-formed airfoil-type.

Figure MS-5. Traq ™ Damper

Figure MS-6. Return air damper building comfort. A centralized microprocessor provides anti-short cycle timing and time delay between compressors to provide a higher level of machine protection. The unit controls can function as a stand-alone controller ling. The character font is 5 x 7 dot matrix plus cursor. The display is a supertwist liquid crystal display (LCD) with blue characters on a gray/green background, which provides high visibility and interface ease. Meaningful diagnostics are also reported and displayed at the HI panel display.

The HI keypad is equipped with 16 individual touch-sensitive membrane key switches. The switches are divided into four separate sections and password protected to prevent tampering by unauthorized personnel. The six main menus are STATUS, SETPOINTS,

DIAGNOSTICS, SETUP, CONFIGURA-

TION, and SERVICE MODE.

Options

Electric Heating Option

High nickel chrome alloy resistance wire is mechanically staked and welded to corrosion-resistant terminals. Heaters are provided with both manual and automatic temperature control devices.

See Figure MS-4.

3-Stage Electric Heat

These electric heaters have three balanced stages with heating steps of

33, 66, and 100%.

7-Stage Electric Heat

These heaters have three unbalanced stages, resulting in seven steps of 14,

27, 41, 59, 68, 86, and 100%.

Electrical and Controls

Controls

The Trane Packaged Fresh Air unit is completely factory-wired with necessary controls and terminal block for power wiring. Microprocessor controls are provided for all 24-volt and 115-volt control functions. The resident control algorithms make all heating, cooling, drying, and/or ventilating decisions in response to electronic signals from sensors measuring indoor temperature, outdoor temperature, and humidity.

The control algorithm maintains accurate temperature, dew point, and/ or humidity control. It also minimizes setpoint drift and provides better Figure MS-7. Electric heat option

Single Bank Staged

A single heater unit with a two-stage gas valve provides two steps of heat.

Single Bank Modulated

A single heater unit with solid state controls provides close temperature control through regulating manifold pressure. The controls modulate between 50 and 100%.

Dual Bank Staged

The heater bank contains a single-stage and a two-stage unit. This combination results in steps of 25, 50, 75, and 100%.

Dual Bank Modulated

The heater bank contains a single-stage and a modulating unit. The microprocessor sequences the single stage bank with the modulating bank to provide capacity control between 25-100% heating capacity. This combination results in 25 to 50% modulation, a 25% step, and 75 to 100% modulation.

Hydronic Heat Interface

A bulkhead and coil support is provided downstream of the fan to accept a fieldinstalled one or two-row hydronic heating coil. The unit controller provides a modulating output to control a fieldinstalled water valve and accepts a low temperature limit input signal. The coil supports accept a standard Trane

33X36” heating coil for the small cabinet and 33X48” coil for the large cabinet. Large cabinets may require field-provided blockoffs. Also, if fieldinstalling smaller coils than recommended, additional field modifications or blockoffs must be made. Openings in the unit side panels for piping must also be field constructed.

Condenser Hot Gas Reheat

An indoor reheat condenser is mounted downstream of the evaporator coils.

The indoor and outdoor reheat condenser has parallel circuits. A liquid solenoid valve controls where refrigerant condensation occurs.

Traq™ Damper

Traq outdoor air dampers with flow measurement rings and a ventilation control module are available for airflow measurement and verification. Each damper has a unit-controlled actuator.

See Figure MS-5.

Return Air/Reference Enthalpy

Air returns vertically through the unit base. Dampers are low-leak. Each damper has a unit-controlled actuator.

Inputs are provided for unoccupied economizer control, based upon a comparison of the outside air stream to a definable enthalpy reference point.

See Figure MS-6.

Return Air/Comparative Enthalpy

Air returns vertically through the unit base. Dampers are low-leak. Each damper has a unit-controlled actuator.

Inputs are provided for unoccupied economizer control, based upon a comparison of enthalpies of the return and outdoor air streams.

External Exhaust Interface

The exhaust plenum is internal to the unit cabinet and has one-inch, doublewall, foamed construction. The unit controller provides a binary exhaust fan signal and accepts a binary fan airflow proving input signal from a fieldinstalled exhaust fan.

Corrosion-Inhibiting Coil Coating

The indoor and outdoor coils have a four to six mil protective coating applied by a multiple dip and bake process.

Corrosion-Inhibiting Cabinet Coating

The unit’s interior and exterior surfaces have a four to six mil spray-on protective coating applied with an air-dry process.

LonTalk ® Communications Interface

(LCI-I)

The LCI-I provides an interface to a

Tracer Summit system or other control system that supports LonTalk and the

DAC profile. The LCI-I is a factoryinstalled device and provides a Comm5 interface to a Trane Integrated Comfort

System (ICS). The LCI-I allows control and monitoring of the unit via a twowire communication link.

Generic Building Automation

System (GBAS)

The GBAS module is for use with a non-

Trane building management system.

The module provides a binary input for demand limiting, four analog inputs for setpoint adjustment, and five relay outputs for diagnostic reporting. Inputs can use a potentiometer or 0-5 VDC signal.


The VOM allows programming of the unit with up to five ventilation sequences: smoke purge, evacuation, pressurization, purge, and purge with duct control. Typically a hard-wire short from a smoke detector or fire control panel will cause a binary input on the

VOM to close, thus causing the programmed sequence to occur. These points can be permanently locked to prevent tampering.

Interface for Remote Human

Interface (RHI)

This interface consists of an interprocesor communication board

(IPCB) and is factory-installed in the unit control panel. This component provides a communication bridge for the RHI to up to four units. This option must be installed in the unit to communicate with a remote HI.
