    摘要: An air conditioner which includes ports (22, 23, 24) provided on portions in a refrigerant circuit where oil are liable to gather, such as bottoms of a compressor (1), accumulator (5), a receiver (12) and the like, through which ports a refrigerant is extracted and charged. The air conditioner is further provided with a control unit (50) for controlling washing operation for the refrigerant circuit, such that at the time of washing of the refrigerant circuit, washing operation is continued under the control of the control unit (50) for a predetermined period of time while increasing a frequency of the compressor (1) so as to, for example, make a temperature in a discharge pipe (2) higher than a predetermined value, and then is stopped, and the washing operation is resumed after a fixed period of time. In the air conditioner, washing of the refrigerant circuit is efficiently and effectively performed by repeatedly staring and stopping the operation of the compressor (1) predetermined times within a predetermined period of time. After washing, the refrigerant and an oil are replaced through ports (22, 23, 24).
