クル。In a refrigeration cycle in which high-pressure refrigerant from the compressor is introduced into the evaporator for defrosting; a pressure reducing circuit is placed in parallel with the piping connecting the evaporator and the compressor, and the piping is connected to the compressor from the evaporator. A switching valve is provided for selectively switching the refrigerant flow path leading to the compressor to either the piping side or the pressure reducing circuit, and the switching valve is operated by a pressure switch attached to the suction side of the compressor. refrigeration cycle.
