Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator having a plurality of evaporators in which high storage quality of food is ensured through freezing cycle exhibiting high cooling efficiency. SOLUTION: A compressor 51, a condenser 52, a capillary tube 53, a first evaporator 48 in a refrigeration compartment 46, and a second evaporator 49 in a freezing compartment 47 are coupled in series to constitute a refrigeration cycle. A refrigerant flow rate varying unit 50 is disposed between the first evaporator 48 and the second evaporator 49 and the difference between the room temperature and the evaporation temperature is reduced by controlling the evaporation temperature of the first evaporator 48 and the second evaporator 49 variably. According to the arrangement, efficiency of the refrigeration cycle is enhanced and storage performance of foods is enhanced by suppressing room temperature variation or dehumidifying function.

Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator capable of variably controlling evaporating temperatures of a plurality of evaporators and having a small temperature change in a cooling chamber and high efficiency. SOLUTION: The refrigerator comprises a compressor 21, a condenser 22, a first evaporator 24 and a second evaporator 25 connected in series to constitute a refrigerating cycle having at least a refrigerant flow varying unit 26 provided between the evaporator 24 and the evaporator 25. In this case, evaporating temperatures of the evaporator 24 and the evaporator 25 are variably controlled by the unit 26, thereby optimally controlling the temperatures of the evaporator 24 and the evaporator 25 and a refrigerant circulating amount. Thus, a temperature change of an object to be cooled can be reduced, and an efficiency of the refrigerator is improved.
