PROBLEM TO BE SOLVED: To sufficiently supply oil to a compressor deficient in oil in a short time. SOLUTION: This air conditioner wherein a plurality of compressors are arranged in parallel and the cooling and heating operations can be switchably performed, is provided with an oil reservoir for storing a part of the oil separated by an oil separator. Further an oil distribution tank is connected with the oil reservoir tank for storing the oil by moving the oil in the oil reservoir tank by utilizing pressure difference in a refrigerant circuit. The oil distribution tank is connected with the plurality of compressors respectively through oil supply pipes. Thus the oil separated by the oil separator can be stored in the oil reservoir tank, and the shortage in supplying the oil to the plurality of compressors can be prevented.
