To prevent an accidental fault without forming a contact part in sealed structure by providing a power switch that is provided between the power cord of the refrigerating device of a chlorofluorocarbon refrigerant and the body of the refrigerating device in a lower chamber where a leakage refrigerant gas can be accumulated easily due to dead weight.

A refrigeration cycle where an HC refrigerant is sealed is integrated into a refrigerator body 7, a compressor 1 is arranged in a lower machine chamber on the rear surface of the refrigerator, one portion of a radiator 2 is arranged in the machine room and the other portions are arranged at a heat-insulating material at the rear surface, side surface, front surface, or the like of the refrigerator body 7, and a termination part is connected to a capillary tube via a dryer. The outlet part of the capillary tube is connected to a cooler 4 that is arranged in the refrigerator and is returned to the compressor 1 through return piping to the outlet of the cooler and the compressor 1. The refrigerator cannot be operated only by providing a manual power switch 10 between a power cord 14 of the refrigerator and the refrigerator body and inserting the power plug of the refrigerator into the receptacle in a chamber.
