Document Type and Number:
Japanese Patent JP6177605
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator having high energy saving performance by controlling a heating amount by a dew condensation prevention pipe, a high temperature refrigerant inflow amount to an evaporator and an evaporation pressure.SOLUTION: A refrigerator includes: a dew condensation prevention pipe 43 which heats an opening edge of a heat insulating box 10; a first refrigerant flow passage A which flows a refrigerant discharged from a discharge port of a compressor 24 in heat radiation means 41, 42, the dew condensation prevention pipe 43, pressure reducing means 44, an evaporator 7 and a suction port of the compressor 24 in this order; and a second refrigerant flow passage B which flows the refrigerant discharged from the discharge port of the compressor 24 in the heat radiation means 41, 42, the pressure reducing means 44, the evaporator 7 and the suction port of the compressor 24 in this order. Between the heat radiation means 41, 42 and the dew condensation prevention pipe 43, and between the dew condensation prevention pipe 43 and the evaporator 7, refrigerant flow passage control means 110, 100 are provided. The refrigerant flow passage control means 110, 100 perform: switching between the first refrigerant flow passage A and the second refrigerant flow passage B; change of restriction of the pressure reducing means 44; and switching of communicating/blocking of the refrigerant flow passage between the dew condensation prevention pipe 43 and the evaporator 7.
