A refrigeration appliance has a cabinet having a first compartment, a second separate compartment and a refrigeration system including a compressor, an evaporator and a condenser. The evaporator is associated with the first compartment to lower a temperature of the first compartment air. A heat exchanger is exposed to the temperature of the first compartment and has a surface area exposed to second compartment air. An air moving device is associated with the second compartment to direct a flow of second compartment air over the heat exchanger surface area and circulate the second compartment air within the second compartment. The cabinet, compartments and heat exchanger are configured such that first compartment air is completely isolated from second compartment air.

1. A refrigeration appliance comprising: a cabinet having a first compartment and a second separate compartment,a refrigeration system including a compressor, an evaporator and a condenser, the evaporator being associated with the first compartment to lower a temperature of the first compartment air
1. A refrigeration appliance comprising: a cabinet having a first compartment and a second separate compartment,a refrigeration system including a compressor, an evaporator and a condenser, the evaporator being associated with the first compartment to lower a temperature of the first compartment air,a heat exchanger being exposed to the temperature of the first compartment and having a surface area in the form of a flat plate with a plurality of ribs exposed to second compartment air,an air moving device associated with the second compartment to direct a flow of second compartment air over the heat exchanger surface area and circulate the second compartment air within the second compartment, the air moving device arranged to operate at a speed to produce a volume flow rate of air greater than 8 cfm and not greater than about 25 cfm in the second compartment, the ribs on the plate being oriented in a direction of air flow of the second compartment air over the plate,the cabinet, compartments and heat exchanger being configured such that first compartment air is completely isolated from second compartment air. 2. The refrigeration appliance of claim 1, wherein the heat exchanger comprises an air passage for only second compartment air and comprises no air passages for first compartment air. 3. The refrigeration appliance of claim 1, including a first air moving device in the first compartment, a first temperature sensor in the first compartment in communication with a control to operate the first air moving device and the refrigeration system, a second temperature sensor in the second compartment in communication with the control to operate the air moving device in the second compartment, and wherein operation of the first air moving device is independent from operation of the second compartment air moving device. 4. The refrigeration appliance of claim 1, wherein the heat exchanger is located at a wall separating the first compartment from the second compartment. 5. A refrigeration appliance comprising: a cabinet having a first compartment and a second separate compartment,a refrigeration system including a compressor, an evaporator and a condenser,a first fan in air flow communication with the first compartment to direct a flow of first compartment air over the evaporator and circulate the first compartment air within the first compartment to lower a temperature within the first compartment,a heat exchanger having a metal plate with a first surface area in thermal communication with the first compartment and having a second surface area exposed to second compartment air,a second fan in air flow communication with the second compartment to direct a flow of second compartment air over the heat exchanger second surface area and circulate the second compartment air within the second compartment, the second fan arranged to operate at a speed to produce a volume flow rate of air in the range of 20 to 25 cfm in the second compartment,the second surface area being provided with a plurality of ribs oriented in a direction of air flow of the second compartment air over the plate,the cabinet, compartments and heat exchanger being configured such that no surface area or space is exposed to both first compartment air and second compartment air. 6. The refrigeration appliance of claim 5, wherein the heat exchanger comprises an air passage for only second compartment air and comprises no air passages for first compartment air. 7. The refrigeration appliance of claim 5, including a first temperature sensor in the first compartment in communication with a control to operate the first fan and the refrigeration system, a second temperature sensor in the second compartment in communication with the control to operate the second fan, and wherein operation of the first fan device is independent from operation of the second fan. 8. The refrigeration appliance of claim 5, wherein the heat exchanger is located at a wall separating the first compartment from the second compartment.
