It has a compressor, a condenser, a liquid receiver, a solenoid valve, an expansion valve, and a cooler. The high-temperature, high-pressure refrigerant compressed by the compressor is heat-exchanged with the atmosphere by a condenser to form a high-pressure liquid refrigerant. The refrigerant is expanded into a low-temperature, low-pressure refrigerant by expanding the refrigerant from a receiver through an expansion valve through an electromagnetic valve, and the low-temperature, low-pressure refrigerant is supplied to a cooler installed in a showcase to cool the air in the refrigerator, thereby reducing the temperature of the refrigerator. The inside of the case is cooled to a predetermined temperature. Then, the refrigerant which has been cooled by giving cold heat to the internal air by the cooler is sucked into the compressor again and circulates on the same path.
