My car has a small fan that pushes inside the car warm air from the engine during cold seasons after parking the car. Why not the same concept pushing cold air into a refrigerator through a pipe that goes outside the house during the winter. The small fan with a thermostat activated gate would open or close the access to the outside keeping the temperature inside the refrigerator constant. If the temperature begins to rise, the motor would activate the compressor as backup power.
