Air Handling and Radiant
Heating and Cooling Systems
Modern, more and more hermetical buildings, do not ensure suitable air
exchange. In order to guarantee health, comfort and to maintain the building
value it is necessary to include ventilation systems for air renewal and humidity
control.
RDZ solution consists in specific devices defined as dehumidifiers. These are
refrigeration units with hydronic coils that thermodynamically treat the air. The
air passes through these dehumidifiers, where it is filtered, cooled, further
cooled and dehumidified, heated and then post-cooled. The air which is taken
in at a certain temperature and with a high humidity value, is thus sent back into
a strongly dehumidified room but at the same starting temperature.
The combination among a dehumidifier, a properly dimensioned and constructed
heat recovery unit and a specific ventilation system creates something which is
very similar to the AHU (Air Handling Unit). Yet, this special combination implies
additional functions such as dehumidification, renewal, free-cooling, thermoventilation and the integration of sensible heat. These functions are obtained
in a very simple way by using both heating and cooling energy with minimum
consumption. That is why these units represent the ideal complementary
element of a radiant installation.

The Comfortable Climate All Year Round
Comfort also means air quality: fresh air, rich in oxygen, taken in from outside,
filtered and dehumidified. RDZ offers a complete range of units, which can be
successfully used in combination with radiant systems for air renewal and for
efficient control over summer hygrometric conditions. There are various models
available, depending on their use in residential or commercial applications:

The picture shows a house with a radiant underfloor heating/cooling system
and RNW 404-CS dehumidifier with air intake duct installed into the false
ceiling in the passage (functioning as supply plenum). The dehumidifier
recirculates the air within the room and dehumidifies it in summer. The process
consists in filtration, cooling, further cooling together with dehumidification,
heating and subsequent post-cooling. In this way only the humidity level is
reduced, and neutral air is given back into the room.
RNW 404 and RNW 411 dehumidifiers, in combination with HR 140 heat
recovery unit, make it possible to renew the air in both summer and winter.

RNW Dehumidifiers
for Relative Humidity Control
in Radiant Cooling Systems
RDZ radiant systems guarantee maximum summer cooling performance
when they are combined with suitable air dehumidification to maintain room
comfort and eliminate the risk of condensation. That is why RDZ offers a
complete range of machines, called RNW dehumidifiers, specific for radiant
systems and available in different models according to actual requirements.
Every machine has a refrigeration unit with two additional heat exchangers,
exploiting the availability of the cold water (15-18 °C) that is used in the
radiant panels. The pre-condenser coil unit, situated immediately before the
evaporator, lowers the air temperature, thus reducing the sensible heat on
the evaporator coil; the post-condenser coil, positioned after the condenser,
reduces the air temperature before giving it back into the room. This process
produces dehumidified air at the same temperature as the one in the room.
As a result, RNW dehumidifiers basically control “latent heat”. This system
also ensures higher efficiency from the chiller, because it can provide the
radiant panels with water at a higher temperature than the one which is
usually necessary for the dehumidification.

Air handling unit with high heat recovery efficiency. It is
used for summer dehumidification with fresh air flow
regulation or partial air recirculation. The renewal air flow
rate, from 80 to 160 m3/h, can be set through the user
interface and automatically detected. It consists in a
single unit made up of two sections, heat recovery section
and air handling section (condensed with water). It is
horizontally installed into false ceilings, and it is equipped
with air vents on the two shorter sides in order to ensure
easier air duct connection and installation even in narrow
spaces. The high efficiency (~90%) heat exchanger is
situated on the countercurrent air discharge side.
The following operation modes can be set through the user
remote control: air renewal, ventilation, dehumidification,
summer and winter sensible heat integration. The unit
is equipped with one pre-installed and electrically
connected motorised damper for automatic recirculating
air flow control. It can be optionally combined with two
additional motorised dampers to avoid annoying draughts
of fresh air (e.g. very cold unprotected windy locations).
Another optional is a valve with modulating servomotor to
control air temperature in winter through UC 300-M. It also
controls air temperature in summer when the compressor

Air handling unit with high heat recovery efficiency. It is
used for summer dehumidification with fresh air flow
regulation or partial air recirculation. The fresh air flow
rate, from 80 to 200 m3/h, can be set via the user panel
and automatically detected. Air handling machine built
as a single unit made up of two sections, heat recovery
and air treatment (condensed with air). It is horizontally
installed into false ceilings, and it is equipped with air
vents on the two shorter sides in order to ensure easier air
duct connection and installation even in narrow spaces.
The high efficiency (~90%) heat exchanger is situated on
the countercurrent air discharge side.
The following operation modes can be set through the user
remote control: air renewal, ventilation, dehumidification,
summer and winter sensible heat integration. In particular,
summer sensible heat integration and part of the condensed
latent heat are supplied costlessly, i.e., without using
further energy from the chiller. The unit includes four preinstalled and electrically connected motorised dampers
for automatic function control. The heat discharge unit
within the exhaust duct reduces energy consumption both
during dehumidification and integration modes. Another
optional is a valve with modulating servomotor to control
air temperature in winter through UC 300-MHE. It also
controls air temperature in summer when the compressor
is off. Comfort UC 300-MHE unit can be controlled by Wi
electronic control unit, by external control or autonomously
(work in progress).

Unit Comfort UC 300-MHE Details
Unit Comfort UC 300-MHE includes some very important
structural details:
• It consists in a single unit made up of two sections: heat
recovery part and air handling part (condensed with air).
• The unit has a rectangular shape with air vents placed on
the two shorter opposite sides, which means easier air duct
connection and installation even in narrow spaces.
• The unit is equipped with four pre-installed and electrically
connected motorised dampers for automatic function
control.
• The heat discarge unit is situated in the air exhaust duct.
In this way energy consumption is reduced both during
dehumidification and integration modes.
• Compared to Unit Comfort UC 300-M, Unit Comfort UC
300-MHE has a different refrigeration circuit including an
additional condensation coil in the air exhaust duct. This
means free summer sensible heat (at least cooling 1.2 KW)
without using further energy from the chiller.

RDZ ModulAir
Distribution Systems
RDZ ModulAir is a flexible modular air distribution system including a plenum
and semi-rigid ducts which are used for air intake and discharge, thus ensuring
balanced air flow distribution in all rooms. The system consists in 150 mm ducts to
connect the unit with the distributor, a modular plenum with 9 or 15 vents, flexible
ducts made of PE-HD DN 63 and room supply and intake vents.
If you connect one or more distributor vents, you can balance the air flow rate,
room by room, according to the need, without using complex dimensioning and
specific installation, as usually happens with traditional sheet metal ducting.
Connections are installed in a very easy and fast way thanks to an automatic “click
and go” joint system which ensures tight seals.
Since it consists of small diameter pipes, the air distribution system can be
installed into the ceilings, under the floors, into the walls, or even between steel
reinforcing bars before casting the concrete.
All components are treated with antibacterial and anti-static additives to ensure
perfect cleanliness and easy maintenance as mentioned by European standards.
One of the main advantages is the reduction in transmitted noise because all
materials are made of plastic.

Unit Comfort UC 1000 in offices
This picture shows a building with offices, where a radiant heating and cooling
system have been installed into the false ceiling. Unit Comfort UC 1000 has
been placed into the machine room, and it has been provided with air intake
and supply ducts.
Unit Comfort UC 1000 is made up of DA 1000 dehumidifier and SR 1000
heat recovery unit. It is ideal for medium-sized commercial applications
with a medium number of people. It contains motorised dampers to control
dehumidification, ventilation, air renewal (with heat recovery) and summer and
winter sensible heat integration.
In this way, b!klimax radiant ceiling system combined with one or more Unit
Comfort modules becomes a DOAS radiant system (Dedicated Outdoor Air
System). It is not only considered as a highly efficient system, but it also
ensures excellent quality in terms of room comfort, because it combines
room temperature control (sensible heat), through the radiant installation, with
air handling in terms of primary air supply and humidity control. Thanks to
the cross-flow heat exchanger, some energy can be saved, while additional
sensible heat can be supplied on demand.
26
Ductable Units for Commercial Application
with Air Renewal and Dehumidification
DA 700, 1000 and 2000 dehumidifiers are air handling units specifically
designed for radiant heating and cooling systems for floors, ceilings and
walls in commercial application. They contain a direct expansion refrigeration
cycle, and they are equipped with additional heat exchangers for preand post- air treatment. In summer these units dehumidify the room air,
reintroducing it into the room at a neutral temperature; if necessary, they can
also supply additional sensible heat in combination with the radiant system.
SR 700, 1000 and 2000 heat recovery units are combined with the relevant
dehumidifiers in buildings, where room air renewal is necessary. They are
equipped with high-efficiency aluminium-plate heat exchangers to save the
sensible energy from the exhaust air flow.

Unit Comfort UC 700/1000/2000
Unit Comfort 700 / 1000 / 2000 can work at the following operating modes: ventilation only, dehumidification, summer
and winter sensible heat integration, air recirculation and air renewal.
• Ventilation function with Unit Comfort activates two standard fans, one in DA and one in SR unit. This ensures
larger head to exhaust air.
• By closing the Dehumidification contacts, the unit begins to dehumidify and keep the same neutral supply
temperature as the intake one. The temperature is preset at 26°C but this value can be changed.
• The Integration function in summer is activated by closing the integration contacts. The units start dehumidifying
the room air by introducing a certain degree of sensible heat into the room. The parameter of the room temperature
can be set by the user. The Integration function in winter just activates the ventilation or air renewal functions
thereby causing hot water to circulate. In this mode the dehumidification operation is disactivated.
• Recirculation is the default operating mode of the two combined DA and SR units guaranteeing dehumidification
and integration by recirculating room air.
• Air Renewal function is activated by closing the renewal contacts. The units move the dampers so as to change
air flow and after a while they turn on the discharge fan. At this point, during summer, the units begin to dehumidify
or integrate, totally renewing the air (or partially renewing it in case of partialised dampers). During winter the units
take some air from outside, which passes through SR heat exchanger before being supplied into the room.
