ABSTRACT:
A method and apparatus for achieving efficient utilization of the thermal energy generated by the indoor fan motor of an indoor unit of a reverse cycle air conditioning system is disclosed. A method is provided for dissipating the thermal energy of the fan motor to the indoor air stream when the heat exchanger is in the heating mode of operation and for dissipating such thermal energy to a heat sink when the indoor unit is operated in the cooling mode of operation such that the fan energy may either be added to the amount of heat energy being supplied to the enclosure or may be dissipated outside the enclosure such that it is not added to the cooling load of the enclosure when the system is operated in the cooling mode.
