空気調和機。[Scope of Claim for Utility Model Registration] (1) A refrigerant circuit configured by successively communicating a variable capacity compressor, a four-way valve, an indoor heat exchanger, a pressure reducing device, an outdoor heat exchanger, etc., and an outdoor heat exchanger. A defrosting timer for controlling defrosting of a container and a variable frequency device for controlling operation of a compressor are provided, and the defrosting operation is performed by circulating high temperature and high pressure refrigerant of the compressor to an outdoor heat exchanger. In this air conditioner, during defrosting operation, the operating frequency of the compressor is lowered to perform low capacity operation a certain period of time before the defrosting is completed by the defrosting timer, and the defrosting operation is terminated by the defrosting timer. An air conditioner characterized in that it returns to heating operation afterward. (2) During the defrosting operation of the outdoor heat exchanger, when the temperature of the outdoor heat exchanger reaches the preset temperature, the operating frequency of the compressor is lowered to perform low capacity operation, and the defrosting operation is performed. The air conditioner according to claim (1), wherein the air conditioner returns to heating operation immediately after the heating operation ends.
