It is equipped with means for detecting a cold air temperature difference between the inlet and outlet of the evaporator, and when the cold air temperature difference reaches a first set value during the cooling operation, the electromagnetic on-off valve is closed for a certain period of time to perform natural defrosting of the evaporator, and then the cooling operation is continued. A refrigeration system configured to operate a heating means to forcibly defrost an evaporator when a cold air temperature difference reaches a second set value that is larger than the first set value.
