Abstract
The invention relates to controls for a refrigeration assembly of the type having freezer and utility compartments with the freezer compartment having the greater cold requirement. The compartment evaporators are in parallel fluid flow lines with an electrically operated blocking device such as a PTC resistor being in the utility compartment line. Thermostats in the two compartments control the flow of refrigerant to the two compartments in a manner such that at the beginning and end of a cycle both compartments are supplied with refrigerant fluid while during the middle part of the cycle only the freezer compartment is supplied with refrigerant fluid.
