1-1. What is DVM?
The DVM(Digital Variable Multi) air conditioning system is operated by a variable-capacity compressor
and is accommodated by multiple evaporators (indoor units). It is touted as the next-generation modular
system in the world of high-efficiency air conditioning. lt has undoubtedly changed the face of cooling
associated with high-storied buildings. It provides a broad range of different commercial applications for
settings such as offices, hotels and schools. With its easy installation and simple control system, the DVM
will more than meet the demands of the air conditioning market.

1-2. Features of DVM
1) The performance of the Digital Scroll compressor
• There will be running cost savings due to the high efficiency of the compressor.
• The wide capacity range will be able to control the room temperature and humidity very precisely for customer’s
comfort.
• The whole system is very reliable; the compressor is extremely reliable and the electronics is simple and the oil
return very well for system operation.
• No electromagnetic interference issue.
2) Pressure chamber of the Digital Scroll compressor
This cross section shows the top part of the Digital Scroll
compressor. It is designed for efficiency, reliability and durability.
The Digital Scroll can give a capacity range of 10% to 100%,
which is the widest in the industry. It has very excellent performance
and needs very simple electronics for operation.

◆ The Digital Scroll operates in 2 states: loaded state and unloaded state. There is an external solenoid valve in the
Digital Scroll. When a 220V signal is given to the solenoid valve, the top scroll moves up by about 1 mm.
The movement of the top scroll creates a gap between the 2 scroll elements and there is no axial sealing between the
scrolls. As a result, even though the motor is running, the compressor is unable to compress any refrigerant.
The capacity in the loaded state is 100% and during the unloaded state is 0%. Capacity from the compressor is a
time average of the loaded state and the unloaded state. For example, in a cycle time of 20 seconds, if the scrolls are
loaded for 10 seconds and unloaded for 10 seconds, the time-averaged capacity is 50%.
to control the cooling/heating system automatically
The PWM valve is designed specially as a solenoid valve to modulate the pressure forcing on the fixed scroll and
finally working on the compressor’s loading/unloading between the upper part of the fixed scroll and the suction pipe.
The PWM receives the On/Off signal and controls the loading/unloading status. When the PWM valve is turned off,
the fixed scroll is pushed down to the orbiting scroll (Loading). When the PWM valve is turned on, the fixed scroll is
separated from the orbiting scroll (Unloading). This process is repeatedly done to make the outdoor unit controlling
automatically depending on the number of operating indoor unit(s) and their weighting factors.

5) EEV(Electronics Expansion Valve) : Optimized refrigerant control
EEV distributes the optimized refrigerant to each indoor
units with the least energy generated from the Digital
Scroll compressor loading/unloading function.
The indoor units senses not only the temperature
difference between inlet and outlet of evaporator but
also the superheat and room temperature profiles and
finally determines the refrigerant flow rates directly
linked with EEV steps.

6) Unloaded power consumption is 10% of full load power in 6.0HP compressor
The graph shows that the unloaded power consumption is 10%
of full load power in case of 6 seconds loaded and
6 seconds unloaded.
In each cycle of modulation, the discharge pressure builds up
during the cycle is being loaded, then the discharge pressure
decreases during the cycle is being unloaded. Similarly, the
suction pressure decreases during the cycle is being loaded and
it increases during the cycle is being unloaded.
The transition time means the time to build up the pressure and
it is a fraction of a second. The average value is around 0.4
second. During transition time, the compressor capacity is much
less and this causes the average compressor capacity to be less
than the modulation percentage. Literally, a shorter transition
time gives better capacity from the compressor.

8) Long pipes for easy installation and construction
• Fits best for constructing a big commercial building
and renovation
• The refrigerant pipe length between the outdoor and
indoor unit at can be extended up to 100 meters.
• The distance from the first refnet joint to the
indoor unit ≤ 30 meters.
10
15m Height between indoor units
• Equivalent piping length between outdoor and
indoor units ≤ 125(For 10.0Hp).
100m Max. piping length
• The value is calculated from the case where the
outdoor unit is installed above the indoor unit. If the
outdoor unit is located underneath the indoor unit,
the level difference would be the maximum of
40 meters.
50m Height between indoor and outdoor unit
• Height between indoor and outdoor unit can be
extended 50 meters.

10) Easy oil return
• Easy oil return during low load operation
• No oil trap necessary
• Loaded cycle gas velocity sufficient to return oil
• No need to use oil separator or oil return cycle
For multi evaporator systems, oil return is a matter of concern.
Because at lower capacities, the gas velocities are lower and this
reduces the ability to return enough oil back to the compressor.
An inverter compressor has to go to a high speed periodically for
returning oil back adequately to the compressor.
The Digital Scroll system has no problem in returning oil even at low
capacities. Even at low capacities, the compressor runs at full loading
with the modulated intervals and while performing full capacity,
the compressor is pumping at full capacity, thus it shows the oil
return with high refrigerant velocity.
The second reason is that at low capacities, the compressor
continues to be unloaded for a longer period. In the unloaded state,
the compressor does not pump out any oil. Thus at lower capacities,
less oil leaves the compressor. No separate oil management system
is required for the Digital Scroll system.

3. Selection procedure
3-1. Selection procedure standard of DVM system based on cooling load
1) Indoor unit selection
Select the nearest load capacity indoor unit with given load after finding indoor and outdoor temperature
using indoor unit capacity table. (The indoor unit capacity should be larger than the given load)
◆ The described capacity may be different to each indoor unit according to combination.
So, the real capacity should be calculated with outdoor unit capacity table.
2) Outdoor unit selection
The allowable combination is described on the indoor unit combination from total capacity index table below.
For the standard of indoor unit and outdoor unit combination, select the nearest value that the total indoor unit
capacity index is less than a 100% outdoor unit combination capacity index.

3) Actual performance data
(1) Select the exact table according to outdoor unit model and combination rate using outdoor
unit capacity table. According to given indoor and outdoor temperature, find outdoor unit
capacity and power input using the table.
Each indoor unit capacity (power input) is calculated as follow.
IUC=OUC x INX/TNX
IUC: Each indoor unit capacity (power input)
OUC: Outdoor unit capacity (power input)
INX: Each indoor unit capacity index
TNX: Total capacity index
(2) According to pipe length, change the indoor unit capacity. If the changed capacity is smaller
than load, change it to the larger capacity of indoor unit and repeat the selection progress.

(2) Indoor unit selection
Select the suitable capacity for condition of 'Indoor WB 20°C, Outdoor DB 33°C' using indoor unit capacity
table. The selected result is as follow.

(3) Outdoor unit selection
1. Assume the indoor unit and outdoor unit combination as follow.
Outdoor unit: RVMH100GAM0
Indoor unit: AVMKH026EA0 x 2, AVMKH035EA0 x 2, AVMCH052EA0 x 1, AVMCH070EA0 x 1
2. Indoor unit combination total capacity index
2.6x2 + 3.5x2 + 5.2x1 + 7.0x1 = 24.4, (24.4/28.0) x 100% = 87%
3. Result: Because it is within 50~130%, it is 'Right' selection (Within 100% for the Middle East).
(4) Real function data with indoor unit combination
1. For the 87% combination, calculate the cooling capacity of outdoor unit (RVMH100GAM0).
27.14kW ← 90% (Indoor temperature: WB 20°C, Outdoor temperature: DB 33°C)
24.12kW ← 80% (Indoor temperature: WB 20°C, Outdoor temperature: DB 33°C)
Therefore, 26.23 = 24.12 + {(27.14-24.12)/10}x7: Calculated in 87%
2. Outdoor unit (RVMH100GAM0) cooling capacity: 26.23kW ← 87%
(Indoor temperature: WB 20°C, Outdoor temperature: DB 33°C)
