Mechanism of Dehumidification Heat Pump
Dehumidification Heat Pump = Dehumidification + heat recovery
Mechanism of Low Temperature Drying
The hot dry air flows through wet materials and takes away moisture thus becomes hot wet air, which then passes through the cold end of heat pump and condenses the absorbed water (dehumidification). The cold dry air after dehumidification is then heated by the hot end of heat pump and becomes hot dry air (energy recovery). A new cycle starts.
