ABSTRACT:
A two-temperature refrigerator appliance having a refrigerator unit operated by a single compressor set, a refrigeration loop with two evaporator sections connected in series, one evaporator associated with a cold compartment and the other with a warmer compartment, a control element associated with the colder compartment disposed in the electric circuit of the compressor set, a control element associated with the warmer compartment having a constant switching-on point above the freezing point, several heating elements switched on by said warmer compartment control element with one heating element disposed adjacent a refrigerant collector connected to the refrigeration loop and another element disposed adjacent the sensor of the colder compartment control element, and at least one intermittently operated additional switching element disposed in the electric circuit of the compressor set. In the preferred form there is a double-throw switch for a defrosting heater, an on-off switch controlling the compressor set independently of the control element in the colder compartment, and a third switching member in the circuit of the double-throw switch and associated with the on-off switch whereby closing the on-off switch opens the switching member and vice versa.
