<P>PROBLEM TO BE SOLVED: To provide a refrigerator that suppresses dew condensation on a refrigerator wall surface and has high energy-saving performance. <P>SOLUTION: The refrigerator 1 includes a heat insulating box 10, a compressor 24, a first heat exchange means 41 for exchanging heat with outside air through an external surface of the heat insulating box 10, a second heat exchange means 7 for exchanging heat with air in the heat insulating box 10, and a decompression means 42. The refrigerator connects the compressor 24, first heat exchange means 41, decompression means 42, and the second heat exchange means 7 in order by refrigerant piping 70, and cools the interior of the refrigerator through the use of a refrigerant radiating heat by the first heat exchange means 41 and absorbing the radiated heat by the second heat exchange means 7. Further, the refrigerator includes a third heat exchange means 40 arranged outside the heat insulating box 10 for heat exchange with the outside air and a refrigerant flow passage switching means 101 arranged for passage switching so that the refrigerant discharged from an outlet 24o of the compressor 24 flows to the second heat exchange means 7, decompression means 42, third heat exchange means 40, and a suction port 24i of the compressor 24 in order so as to defrost the second heat exchange means 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
