Technical Examples

To prevent refrigerant in a refrigeration cycle from releasing into a vehicle compartment, in large amounts, due to breakage of an evaporator disposed on a compartment side or piping thereto. An expansion device is formed by an expansion valve that supplies throttled and expanded refrigerant to an evaporator, an electromagnetic valve connected in series to the expansion valve, and a check valve that prevents backflow of refrigerant flowing out of the evaporator, and a release-to-atmosphere device is provided in low-pressure piping connected to the compressor, for allowing the refrigerant therein to be released into the atmosphere. As a result, when refrigerant in the evaporator has released, or when there is a possibility of refrigerant releasing from the same, the electromagnetic valve is closed to isolate the evaporator from high-pressure piping of the refrigeration cycle, and at the same time the release-to-atmosphere device is opened to thereby dispose of the refrigerant in the low-pressure piping, outside the vehicle compartment. As a result, safety of occupants is ensured.
