置。 The refrigerant from the compressor is sequentially supplied to a first cooler disposed in the freezer compartment and a second cooler that is cooled to a lower temperature than the first cooler and circulates cold air into the freezer compartment. In the refrigeration cycle, a solenoid valve is provided between the first and second coolers, and the solenoid valves are opened and closed according to operation and stop of the compressor to defrost the second cooler. A refrigeration cycle operating device comprising a control circuit that closes the electromagnetic valve when a defrosting signal is applied and then continues to operate the compressor for a predetermined period of time.
