Refrigerator with two doors has cool box in lower part and freezer compartment in top part and has separate cooler and freezer evaporators

摘要

The cooling circuit (Cr) has a freezing compartment (Vz) and a cooling compartment (Vf) each with its own evaporator coil (Ez,Ef). There is a single compressor (K) followed by a condenser (C), a hot tube (TC) and a filter (F). A three-way solenoid valve (EV) follows the filter and is connected to a thermostat (TE). The circuit includes cooler and freezer capillary tubes (Lf,Lz) and there are heat exchangers (SC1,Sc2) using the cold vapor returning from the evaporators to pre-cool the liquid going to the evaporators.
