Unit configuration and operation of CAIRfricostar / Micro compact units
Thanks to the modular design of the units and various applications for each case, a
customer can select a wide range of unit configurations. Refer to the following exam-
ples demonstrating the basic unit design and its operating principles.
1.1 CMU units
The FläktGroup CAIRfricostar CMU is designed for private and small public swimming
pools. The series is available in 6 sizes.
The unit's function is to dehumidify and heat air in swimming pools in mixed air mode.
The unit is delivered with a DDC controls which regulates all functions of the system
on a fully automated basis.
Fig. 1-1
When in stand-by mode without dehumidification the air is recirculated in the swimming
pool. When the humidity setpoint has been exceeded the unit switches into dehumidi-
fication mode. At this point the supply-air fan is operated at nominal air flow and the
extract-air fan maintains the proper air movement. The refrigeration unit is activated in
order to start dehumidification. Using the bypass damper a certain part of return air is
mixed without further treatment with dehumidified air that has passed through the
refrigeration cycle. The dehumidification stage continues until the actual humidity value
lies below that of the humidity setpoint. Then the refrigeration unit is deactivated.
When in active hours swimming pool mode the fresh and exhaust air dampers are
opened, the bypass damper is closed. To start dehumidification the refrigeration unit is
activated.
Using an optional pool water condenser a certain amount of excess energy produced
by the refrigeration cycle can be fed back into swimming pool water.

1.2 CAM units
The FläktGroup CAIRfricostar CAM is designed for various kinds of private and public
swimming pools. This unit series can deliver air flow rate from 750 up to 45.000 m³/h.
The unit's function is to dehumidify and heat air in swimming pools in mixed air mode.
Besides a refrigeration unit (heat pump) this unit type is additionally equipped with an
efficient heat recovery system. The unit is delivered with a DDC controls which regu-
lates all functions of the system on a fully automated basis.
Fig. 1-2
When in stand-by mode without dehumidification the air is recirculated in the swimming
pool. When the humidity setpoint has been exceeded the unit switches into dehumidi-
fication mode. At this point the supply-air fan is operated at nominal air flow and the
extract-air fan maintains the proper air movement. The refrigeration unit is activated in
order to start dehumidification. Using the bypass damper a part of return air is mixed
with air dehumidified through the refrigeration unit. The dehumidification stage contin-
ues until the actual humidity value lies below that of the humidity setpoint. Then the
refrigeration unit is deactivated.
When in active hours swimming pool mode the fresh and exhaust air dampers are
opened, the bypass damper is closed. Then the refrigeration unit is activated. In the
event of overheated swimming pool the refrigeration unit is deactivated and the bypass
dampers are opened to divert the heat recovery system.
Using an optional pool water condenser a certain amount of excess energy produced
by the refrigeration cycle can be fed back into swimming pool water.

1.3 CWR units
The FläktGroup CAIRfricostar CWR is designed for various kinds of private and public
swimming pools. This unit series can deliver air flow rate from 750 up to 45.000 m³/h.
The unit's function is to dehumidify and heat air in swimming pools in mixed air mode.
These units are equipped with an efficient heat recovery facility. The unit is delivered
with a DDC controls which regulates all functions of the system on a fully automated
basis.
Fig. 1-3
When in stand-by mode without dehumidification the air is recirculated in the swimming
pool. When the humidity setpoint has been exceeded the unit switches into dehumidi-
fication mode. For this purpose outside air is supplied continuously. The dehumidifica-
tion stage continues until the actual humidity value lies below that of the humidity
setpoint. After that continuously operating outside air/extract air dampers are closed.
In the pool mode outside air and extract air dampers are opened to ensure a pre-set
minimum rate for outside air for hygienic reasons, the opening of the mixed-air damper
is reduced accordingly. Depending on the swimming pool humidity the outside air rate
is regulated automatically.
In the event of overheated swimming pool the bypass dampers are opened to divert
the heat recovery facility.

1.4 CAT units Micro
The FläktGroup CAIRfricostar CAT is a dehumidifier with compact configuration
designed for private and hotel swimming pools as well as therapeutic baths. This unit
series can deliver air flow rate from 750 up to 6,500 m³/h. The series is available in
5 model sizes.
The unit operates to dehumidify and heat air in swimming pools in mixed air mode and
is equipped with a high-efficiency heat recovery facility and a compressor unit to ena-
ble dehumidification.
The unit is equipped with an integrated DDC control system which regulates all func-
tions on a fully automated basis.
Fig. 1-4
When in stand-by mode without dehumidification the air is recirculated in the swimming
pool. When the humidity setpoint has been exceeded the unit switches into dehumidi-
fication mode. For this purpose the refrigeration unit is activated. Part of return air is
mixed with dehumidified air using the bypass damper. The dehumidification stage con-
tinues until the actual humidity value lies below that of the humidity setpoint. Subse-
quently the refrigeration unit stops and air is recirculated in the swimming pool, all
values are monitored.
When in active hours swimming pool mode the fresh and exhaust air dampers are
opened, the bypass damper is closed. To start dehumidification the refrigeration unit is
activated. The unit operates to deliver the pre-set hygienic minimum rate of outside air.
Depending on the swimming pool humidity the latter is regulated continuously.
In the event of overheated swimming pool the bypass damper is opened to divert the
heat recovery facility.
Using an optional pool water condenser a certain amount of excess energy produced
by the refrigeration cycle can be fed back into swimming pool water.

1.5 CWT units Micro
The FläktGroup CAIRfricostar CWT is a dehumidifier with compact configuration
designed for private and hotel swimming pools as well as therapeutic baths. This unit
series can deliver air flow rate from 750 up to 6,500 m³/h. The series is available in
5 model sizes.
The unit's function is to dehumidify and heat air in swimming pools in mixed air mode.
These units are equipped with a highly efficient heat recovery facility.
The unit is delivered with a DDC controls which regulates all functions of the system
on a fully automated basis.
Fig. 1-5
When in stand-by mode without dehumidification the air is recirculated in the swimming
pool. When the humidity setpoint has been exceeded the unit switches into dehumidi-
fication mode. Supplementary outside air is continuously added to supply air. The
dehumidification stage continues until the actual humidity value lies below that of the
humidity setpoint. Subsequently the unit operates to deliver the pre-set hygienic mini-
mum rate of outside air. Depending on the swimming pool humidity the latter is regu-
lated continuously.
In the event of overheated swimming pool the bypass damper is opened to divert the
heat recovery facility.
