Abstract

The system has a fresh food (above freezing) compartment and a freezer compartment with respectiVe evaporators connected to a common compressor and condenser. Refrigerant is fed to one evaporator or the other via a corresponding one of valves controlled by an electronic circuit. This receives signals from temperature sensors in the respective compartments. The circuit (a microprocessor) is so arranged that when both sensors demand a supply of refrigerant, priority is given to the evaporator of the fresh food compartment, but only for a certain period of time. At the end of the period, even if the fresh food compartment has not achieved its set temperature, refrigerant is diverted to the evaporator of the freezer. The circuit control program has special features for when the apparatus is initially switched on, and provides time delays to stop ON - OFF cycling of the compressor.
