Abstract

A refrigerant circuit for a refrigerator-freezer combination comprises a single compressor, an evaporator each for a re­ frigerating compartment and a freezer compartment, a con­ denser and at least one capillary.
The invention provides the connection of the two evaporators (17, 18) in series, and the employ of two series-connected cap­ illaries (14, 15) one of which is bypassed with the aid of a sole­ noid valve (16).
With respect to an electric control circuit, the invention pro­ vides that a thermostat (23) associated with the refrigerating compartment controls the solenoid valve (16) and a defroster resistor (22) of the refrigerating compartment, while a ther­ mostat (21) associated with the freezer compartment is con­ nected to the compressor (10) and to the thermostat (23) as­ sociated with the refrigerating compartment.
