A REFRIGERATION DEHUMIDIFICATION APPARATUS WITH TWO REFRIGERATION CYCLES AND A DRYING MACHINE MANUFACTURED BY THEREOF

摘要

A refrigeration dehumidification system with two refrigeration cycles and a drying machine using the same are provided to define a refrigeration dehumidification into two parts to be driven alternately for defrosting evaporator coils thereof alternately, thereby maintaining the refrigeration dehumidification operation with high efficiency. A refrigeration dehumidification system with two refrigeration cycles includes two refrigeration dehumidification parts(14,15) for freezing moisture to dehumidify contents in a drying compartment(11), wherein the refrigeration dehumidification parts operate alternately. The refrigeration dehumidification parts have two separated spaces, each being mounted with an evaporator coil, upper and lower dampers(17,22) for controlling air flow, and a defrosting heater(21) for removing frost from the evaporator coil.
