Abstract
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.
