The four-season portable refrigeration dehumidifier adopts the method of direct air cooling refrigerating-rotary united dehumidification, which is suitable for special coating at four seasons for temporary facility. Refrigeration dehumidification is primary and rotary dehumidification is as supplement in summer season, while refrigerating-rotary united dehumidification is used in transition season, rotary dehumidification is used in winter season.

The refrigerating system adopts air cooling type, air cooling machine adopts imported screw compressor, it is convenient for saving energy and improving machine running stability. The air which needs treatment will enter into the cooler for preliminary dehumidification, then the further dehumidification might be proceeded by rotary dehumidification according to the technology requirement.

Under the condition of inlet air temperature -5-40℃ and relative humidity 50-99%, the outlet air can reach temperature 20-32℃, relative humidity≤45%. The condenser adopts air cooling type copper pipe aluminum sheet, the evaporator adopts direct evaporating type copper pipe aluminum sheet. The machine has four working conditions for selection: complete refrigeration, refrigerating-rotary combination, completely rotary, rotary and heating. The machine adopts PLC automatic program operation, meeting the requirement of all working conditions.
