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 refrigeration system on and off as required, and which controls freezer compartment temperature by varying the airflow through a duct conducting refrigerated air from the evaporator chamber to the fresh food compartment. In order to compensate for variations in freezer compartment temperature which would otherwise result when the setting of the fresh food control is changed, the airflow through the duct is varied as a funtion of the setting of the fresh food control, as well as of the freezer control.
