<p>An air-conditioner capable of suppressing increase in the suction temperature of a compressor is provided. The air-condrtioner 100 according to the present invention has a refrigerant circuit in which a compressor 1, an oil separator 2, a heat source side heat exchanger 4, a throttle device 102, and a use side heat exchanger 101 are connected in series, an oil returning circuit 31 that connects the oil separator 2 with the suction side of the compressor 1, and a decompression mechanism 11 provided in the oil return circuit 31. The oil return circuit 31 is installed by piping so as to exchange heat with a part of the heat source side heat exchanger 4 at the upstream side of the decompression mechanism 11.</p> |
