Summary: | An air conditioner provided with a refrigerant circuit formed by connecting with piping a refrigerant compressor, a condenser, an expansion means and an evaporator, an inverter power supply means for controlling the rotational speed of an electric motor for driving the refrigerant compressor, a load detector, and a controller for controlling the inverter power supply means on the basis of an output from the load detector. A refrigerant flow passage controlling mechanism is provided to change the rate at which the refrigerant flows through the condenser on the basis of a control command from the controller, thereby making it possible to reduce or increase the discharge rate without extending the range of changes in the rotational speed of the compressor. The compressor can be controlled according to a wide range of changes in the load to operate with an operation range which ensures high efficiency of the compressor operation. |
