ABSTRACT:
A refrigerating cycle including a cold-accumulation material to be cooled comprises main evaporator for generating cold air to cool a refrigerator compartment, a cold-accumulation evaporator to cool the cold-accumulation material, a flowpath switching device, such as a three-way electromagnetic valve, to change the refrigerant flowpath between a first refrigerant flowpath to the main evaporator and a second refrigerant flowpath to the cold-accumulation evaporator respectively, and a refrigerant supply device, such as a compressor, a condenser, and a capillary tube connected in series, to supply refrigerant to the main evaporator and the cold-accumulation evaporator through the flowpath switching device. The outlet of the cold-accumulation evaporator is connected to the inlet of the evaporator to let the refrigerant which has not completely evaporated in the cold-accumulation evaporator flow into the main evaporator.
