An energy transfer system for a household refrigeration appliance. The energy transfer system includes a compartment for enclosing a condenser which is associated with the refrigeration appliance, and a set of conduits for enabling the transfer of outside air into, through and out of the compartment. The system also includes a movable barrier for selectively controlling the transfer of air through the compartment. In one form of the present invention, the system also includes a thermostatically actuated fan for forcing outside air into, through and out of the compartment in response to a predetermined temperature.
