ABSTRACT:
A heat pump type air conditioner having a refrigeration circuit including a variable speed compressor, a four-way valve, an indoor heat exchanger, an expansion device and an outdoor heat exchanger, and capable of operating in a cooling mode to cool a room and a heating mode to heat the room. The compressor speed is set in accordance with air conditioning load, such as the temperature difference between a setting room temperature and the actual room air temperature and the operation mode. An outdoor fan blows air through the outdoor heat exchanger which selectably rotates at a high speed or a low speed. The rotational speed of the outdoor fan is selected based on the operation mode, a cooling mode reference compressor rotational speed value, a heating mode reference compressor rotational speed value and the set compressor rotational speed. The cooling mode reference compressor rotational speed value is smaller than the heating mode reference compressor rotational speed value.
