ABSTRACT:
A freezer-refrigerator for automotive vehicles, which includes a freezing chamber and a refrigeration chamber. The freezing chamber includes a freezing evaporator and a first cold storage member. The refrigeration chamber includes a refrigeration evaporator and a second cold storage member. Both evaporators are connected in series so that refrigerant flows from a compressor through the freezing evaporator and then through the refrigeration evaporator under a control of a solenoid valve which is controlled by signal from a temperature sensor provided in at least one of the chambers, thus controlling the freezing and refrigeration. The freezing temperature of the second cold storage member is set higher than that of the first cold storage member thereby to maintain the interior of the chambers at a temperature near the freezing temperature of the cold storage members for long time even after the compressor stops. The compressor has a plurality of cylinders with respective pistons at least one of which is operated for the freezing and refrigeration and the other of which are operated for the vehicle airconditioning.
