ABSTRACT:
Energy efficient independent temperature control is achieved in refrigerators by minimizing system run time. A freezer thermostat activates the refrigeration system when the freezer compartment requires cooling and a fresh food thermostat which controls a damper between the two compartments. The two thermostats are operatively connected so that the freezer thermostat is prevented from switching off whenever the fresh food thermostat calls for cooling in the fresh food compartment. Thus, only the freezer thermostat is able to activate the refrigeration system, while either of the thermostats can inactivate the system.
