GEA CAIRfricostarDehumidifier with Air Recirculating and Heat Pump FunctionType CAUFunctional description of the unitThe GEA CAIRfricostar CAU is mainly designed for private swimming pools and canbe delivered in 4 sizes. The unit's function is to dehumidify and heat air in swimmingpools in circulating air mode. The unit is supplied with a fully electronic control systemthat automatically regulates system functions.Operation mode with dehumidification requestIn circulating air mode without dehumidification the air is recirculated in the swimmingpool. The multifunction humidistat that is installed in the swimming pool switches theunit into dehumidification mode as soon as the humidity setpoint has been exceeded.At this point the fan is switched into speed 2 and the refrigeration circuit is activated.The dehumidification process is carried out until the setpoint is reached. After that thefan is switched into speed 1 and the circuit compressor is stopped. Using an optionalpool water condenser a certain amount of excess energy produced by the heat pumpcycle can be fed back into swimming pool water or similar circuit system.Air recirculating dehumidifier CAUSupply air fan runs at high speed. The necessary transmission heat is provided by the reheater coil. Usingan optional pool water condenser a certain amount of excess energy can be fed back into swimmingpool water.System and controls schemeMMMM1MpPPMMpDIAIDOAOPR-2008-0327-GB • Subject to modifications • Status 09/2008 3

In case of an optional bypass of the heat recovery systemthe latter is not used thanks to a damper system and at the sametime the air volume flow is increased ("free night cooling“ function).If the swimming pool is overheated during the night time or idle periodthe unit ventilates only in outdoor/exhaust air mode. The fans run athigh speed and provide cooling of the swimming pool to reach thesetpoint temperature. In case of an optimal bypass of the heat recoverysystem the heat recovery is not used thanks to a damper systemand at the same time the air volume flow is increased.14 PR-2008-0327-GB • Subject to modifications • Status 09/2008

130130130GEA CAIRfricostarDehumidifier with Air Mixing FunctionType CWRFunctional description of the unitThe GEA CAIRfricostar CWR is designed for various kinds of private and public swimmingpools. The series can be supplied with air volume capacity between 750 up to45,000 m³/h. The unit's function is to dehumidify and heat air in swimming pools in airmixing mode. This unit type is additionally equipped with an efficient heat recovery system.The unit is delivered with a DDC controls which regulates all functions of the systemon a fully automated basis.Sample selection of operating modes:When in idle mode without dehumidification the air is recirculated in the swimming pool.When the humidity setpoint has been exceeded the unit switches into dehumidificationmode. For this purpose the supply and exhaust air fans are activated to run at highspeed with continuous mixing of outdoor air. The dehumidification stage continues untilthe actual humidity value is reduced below that of the humidity setpoint. After that thefans are deactivated.Idle mode without dehumidificationrequestActive hours operation mode withdehumidification requestIdle mode with dehumidificationrequest+++---Bypass damper mode, exhaust air fan isdeactivated,supply air fan runs at low speed.Air mixing operation according to VDI,exhaust and supply air fans run at highspeed.

F6F6F7F6F7F6F7Dehumidifier with Air Mixing FunctionType CWPGEA CAIRfricostarFunctional description of the unitThe GEA CAIRfricostar CWP is designed for various kinds High Performance privateand public swimming pools. The series can be supplied with air volume capacitybetween 750 up to 37,500 m³/h. The unit's function is to dehumidify and heat air inswimming pools in air mixing mode. This unit type is additionally equipped with an efficientheat recovery system. The unit is delivered with a DDC controls which regulatesall functions of the system on a fully automated basis.Sample selection of operating modes:When in idle mode without dehumidification the air is recirculated in the swimming pool.When the humidity setpoint has been exceeded the unit switches into dehumidificationmode. For this purpose the supply and exhaust air fans are activated to run at highspeed with continuous mixing of outdoor air. The dehumidification stage continues untilthe actual humidity value is reduced below that of the humidity setpoint. After that thefans are deactivated.In case of overheating of the swimming pool the refrigeration unit is deactivated andthe bypass dampers are permanently open in order to avoid heat recovery system.Idle mode without dehumidificationrequestInactive/active mode with lowdehumidificationActive hours operation mode withdehumidification request at highoutdoor temperaturesBypass damper mode, exhaust air fan is deactivated,supply air fan runs at low speed.Operation with air mixing damper, exhaustand supply air fans run at high speed.
