<P>PROBLEM TO BE SOLVED: To minimize the intrusion of heat into a refrigerator while preventing dew condensation on the outer surface of a heat insulating box body. Ž<P>SOLUTION: The refrigerator includes: the heat insulating box body 19; a first refrigerating cycle 25 connecting a compressor 5, a first condenser 22, a passage selector valve 23, a second condenser 24, a pressure reducing means 9 and an evaporator 10 functionally in annular shape; a second refrigerating cycle 27 connecting the compressor 5, the first condenser 22, the passage selector valve 23, a third condenser 26, the pressure reducing means 9 and the evaporator 10 functionally in annular shape; and a control means 28 switching a refrigerant circulation line to the first refrigerating cycle 25 and the second refrigerating cycle 27. The second condenser 24 is disposed to transmit heat of condensation to the outer surface of the heat insulating box body 19. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
