UC 500-MHE – INSTALLATION, USE AND MAINTENANCE MANUAL DEHUMIDIFICATION AND COOLING The finned coil (3) supplied with the water coming from the radiant system, cools down the air, while the cooling evaporator (4) performs further cooling and dehumidification. The refrigeration circuit is made up of two condensers connected in parallel: in addition to the an air-cooled condenser (5) a second condenser is cooled by the outgoing air flow (6), thus releasing the condensation heat outwards. -
