E A E Kompress or A ECOSTATPower Tube2 E A E A Dehumidifier with Air Mixing and Heat Pump Function Type CAM GEA CAIRfricostar Functional description of the unit The GEA CAIRfricostar CAM is designed for various kinds of private and public swimming pools. The series can be supplied with air volume capacity between 750 up to 45.000 m³/h. The unit's function is to dehumidify and heat air in swimming pools in air mixing mode. Together with the 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 regulates all functions of the system on a fully automated basis. Sample selection of operation mode: 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 dehumidification mode. At this point the supply air fan is switched into speed 2 and the exhaust air fan maintains air circulation at speed 1. 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 is reduced below that of the humidity setpoint. After that the fan is switched back into previous speed and the refrigeration cycle is stopped. When in active hours swimming pool mode the fresh and exhaust air dampers are opened, the bypass damper is closed. The dehumidification takes place via the activation of the refrigeration cycle with both fans switched into speed 2. 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. Idle mode without dehumidification demand Idle mode with dehumidification request Active hours swimming pool mode with humidification request and pool water condenser + + + + + + + + - - - - Bypass damper mode, exhaust air fan is deactivated, supply air fan runs at low speed. Bypass damper mode, exhaust air fan runs at low speed, supply air fan runs at large speed. Compressor is switched on. The reheater provides the missing residual heat supply. Air mixing operation according to VDI, exhaust and supply air fans run at high speed. Compressor is switched on. The reheater provides the missing residual heat supply. Using a pool water condenser a certain amount of excess energy can be fed back into swimming pool water. Transition and summer mode with/w/o dehumidification Summer mode inactive period „free night cooling“ + + + + + + + + - - - - In case of overheating of the swimming pool and high outdoor temperatures the heat pump is blocked. The unit ventilates and dehumidifies in air mixing or only outdoor/exhaust air mode. The fans run at high speed. In case of an optional bypass of the heat recovery system the latter is not used thanks to a damper system and at the same time the air volume flow is increased ("free night cooling“ function). If the swimming pool is overheated during the night time or idle period the unit ventilates only in outdoor/exhaust air mode. The fans run at high speed and provide cooling of the swimming pool to reach the setpoint temperature. In case of an optimal bypass of the heat recovery system the heat recovery is not used thanks to a damper system and at the same time the air volume flow is increased. 14 PR-2008-0327-GB • Subject to modifications • Status 05/2009
