置。 A defrosting refrigerant pipe that connects a compressor, a condenser, a pressure reducer, and an evaporator in order to form a refrigeration cycle with a refrigerant pipe, and allows high-temperature refrigerant of the refrigeration cycle to flow to the evaporator during defrosting operation of the evaporator. In the refrigeration system, a one-way solenoid valve is provided in the suction pipe of the compressor to prevent the refrigerant that has flowed into the evaporator from flowing out during the defrosting operation, and A return pipe is provided to return a part of the discharged refrigerant to the suction pipe of the compressor, and a check valve is provided to allow the refrigerant from the return pipe to flow to the evaporator and to prevent the refrigerant from flowing from the evaporator to the compressor. , A refrigeration system characterized in that the unidirectional solenoid valve is arranged in parallel.
