ABSTRACT:
A single evaporator, single fan combination refrigerator includes a temperature control system which thermostatically maintains the fresh food compartment at a desired temperature by cycling the refrigerator system on and off as required, and which controls freezer compartment temperature by varying airflow through a duct conducting refrigerated air from the evaporator chamber to the fresh food compartment. Variable airflow control apparatus comprising a mechanical summer operating an air valve varies airflow through the duct as a function of the settings of both the fresh food control and the freezer control.
