A refrigerator-freezer includes a first evaporator cooling an atmosphere in a refrigerating compartment, a second evaporator cooling an atmosphere in a freezing compartment and a controller controlling a switching valve in a refrigerating cycle so that a cooling operation is switched between a first operation mode in which refrigerant compressed by a compressor is supplied at least to the first evaporator and a second operation mode in which the refrigerant compressed by the compressor is supplied at least to the second evaporator. The controller stops the compressor when a temperature in either one of the refrigerating and freezing compartments for which the cooling operation is unexecuted is below a predetermined upper limit temperature in a case where a temperature in the other compartment for which the cooling operation is in progress drops to a predetermined lower limit temperature.

Refrigerator freezer with two evaporators for respective refrigerating and freezing compartments

There is provided a refrigerator capable of suppressing intra-compartment temperature from rising during a defrosting operation by means of a defrosting heater and capable of preventing temperature of foods from rising after the defrosting operation. The inventive refrigerator sets temperature for ending a freezing mode during a pre-cooling operation at pre-cooling freezing mode ending temperature which is lower than temperature during a normal operation by a predetermined temperature and conducts an alternate cooling operation until when the pre-cooling operation ends based on the pre-cooling freezing mode ending temperature.
