ABSTRACT:
An air conditioner includes a compressor, an indoor heat exchanger, an expansion tube, and an outdoor heat exchanger interconnected by refrigerant conduits for operation in cooling and heating modes. In a cooling mode, the outdoor heat exchanger conducts ambient air horizontally across heat exchange coils. In a heating mode, the outdoor heat exchanger conducts heated air from an auxiliary gas-fired heater upwardly across those same coils. The outdoor heat exchanger includes movable blades for creating the horizontal and vertical air flow passages for the cooling and heating modes.
