In a dual temperature refrigerator with a single compressor from which refrigerant flows through a condenser and a capillary tube into a first evaporator, and from the first evaporator through a connecting line into a second evaporator, a refrigerant collector being connected to the condenser at the beginning of the capillary tube, the collector having a volumetric capacity equal to that of the second evaporator and being provided with a heater, a control element in the chamber of the second evaporator intermittently activating the compressor and heater, a suction line from the second evaporator to the compressor, and at least part of the capillary tube in heat-exchange contact with the connecting line. Preferably part of the capillary tube is disposed within the connecting line. Desirably the capillary tube and connecting line are disposed in the insulation of the refrigerator. The invention avoids unwanted drastic temperature drops in the chamber of the second evaporator due to overflowing excess liquid and wet vapor from the first evaporator.
