Swimming Pool Dehumidifier is designed to control the moisture & humidity level in the pool. The cabinet of the dehumidifier is equipped with sensors and controllers that ensure impeccable controlling of temperature and humidity. The dehumidifier uses the refrigeration circuit to realize the dehumidification. The system includes compressor, evaporator, condenser, capillary and pipe structure. When the damp air passes the evaporator it will condense and become dry and then will again be heated while passing through compressor.
