Abstract
A refrigerator freezer having an upper refrigerator compartment and a lower below freezing freezer compartment. The upper compartment can be a convertible compartment selectively operable by the user as an above freezing refrigerator compartment or as a below freezing freezer compartment. The evaporator for supplying refrigerated air is located in the upper compartment along with an auxiliary heater and upper compartment thermostat to control the temperature in the upper compartment. A control discharges an amount of refrigerated air to the upper compartment for refrigerator operation and a larger amount of refrigerated air for freezer operation. The control also energizes the auxiliary heater under control of the upper compartment thermostat during refrigerator operation to assure above freezing temperatures in the upper compartment. A low ambient heater can be provided for the upper compartment for use of the refrigerator freezer in low ambient temperature conditions such as an unheated garage.
