Abstract
In a refrigerator, an intermediate heat exchanger as an evaporator in the refrigeration cycle 11 in which a flammable refrigerant is sealed is provided inside of a heat insulating material. A heat transferring device is provided between the intermediate heat exchanger and a heat exchanger for cooling. At the time of stop and occurrence of the refrigerant leakage, the refrigerant inside of the intermediate heat exchanger is recovered into the condenser or into the refrigerant recovery cylinder so that even if the refrigerant leaks out, a leaked amount of the refrigerant into the refrigerator is reduced.
