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.

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.

An air conditioning machine has a unit main body having an inlet port and an outlet port. The unit main body includes a cross flow fan, having a circular cross section, for introducing indoor air into the unit main body through the inlet port and blowing the air into the room. A heat exchanger is arranged on an indoor air introducing side of the cross flow fan and bent at a portion along a longitudinal direction of the heat exchanger at an acute angle. The heat exchanger has a front side heat exchanger located on a front side of the air conditioning machine and curved along the circular cross section of the cross flow fan and a rear side heat exchanger located on a rear side thereof.
