PROBLEM TO BE SOLVED: To stably cool an inner part of a refrigerator while further improving energy saving performance by use of an expansion valve. SOLUTION: The refrigerator comprises a refrigeration cycle formed by successively connecting a compressor 7, a condenser 8, a dehydrator 11, a decompression means 12 and a cooler 6 by a refrigeration pipe 16 so as to return to the compressor again, and the inner part 2 is cooled by the cooler of the refrigeration cycle. The decompression means is composed of an expansion valve, and a condenser outlet-side pipe between the dehydrator and the expansion valve is fitted to an evaporator outlet-side pipe between the cooler and the compressor to thereby form a heat exchange part 21 for heat exchange. Refrigerant which leaves the condenser flows into the expansion valve while maintaining a substantially constant pressure. COPYRIGHT: (C)2008,JPO&INPIT
