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.
