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.

[ We claim:] [1.] A refrigerator-freezer comprising:a refrigerating compartment;a freezing compartment;a refrigerating cycle including a compressor compressing a refrigerant, a condenser condensing the refrigerant supplied from the compressor, a first evaporator cooling an atmosphere in the refrigerating compartment, a second evaporator cooling an atmosphere in the freezing compartment, and a valve switching a cooling operation between a first operation mode in which the refrigerant compressed by the 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; anda controller controlling the compressor and the valve, the controller controlling the valve so that the first and second operation modes are carried out alternately, the controller stopping the operation of 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.
