を設けたことを特徴とする冷凍装置。 In a refrigeration system, the refrigerant circulates through a compressor, a condenser, a throttle device, and an evaporator in this order during cooling operation, and the refrigerant circulates in the reverse direction during defrosting operation.
A pressure switch is installed in the refrigerant passage through which high-pressure refrigerant flows during defrosting operation, and a blower is used to blow air into the condenser until the pressure of the high-pressure refrigerant detected by the pressure switch reaches its operating value during defrosting operation. A refrigeration system comprising a blower control means for stopping the blower when the pressure of the high-pressure refrigerant increases to the operating value.
