AIR CONDITIONER

摘要

A multi-chamber air conditioner capable of a simultaneous cooling / heating operation without leakage of a refrigerant for which an adverse effect on a human body is concerned into a room or the like where an indoor unit is installed is provided. An air conditioner 100 is provided with a heat-source side refrigerant circuit A in which a compressor 11, an outdoor heat exchanger 13, a first heat exchanger 21, a refrigerant flow-rate controller 25, and a second heat exchanger 22 are connected in series, a first use-side refrigerant circuit B1 in which the first heat exchanger 21 and an indoor heat exchanger 31 are connected in series, and a second use-side refrigerant circuit B2 in which the second heat exchanger 22 and the indoor heat exchanger 31 are connected in series, and a heat-source side refrigerant circulating in the heat-source side refrigerant circuit A and a use-side refrigerant circulating in the use-side refrigerant circuit B are heat-exchanged in the first heat exchanger 21, and the heat-source side refrigerant circulating in the heat-source side refrigerant circuit A and the use-side refrigerant circulating in the use-side refrigerant circuit B are heat-exchanged in the second heat exchanger 22.
