<p>The objective is to provide an air conditioner which has high operating efficiency and with which a receiver can be used to adjust the amount of refrigerant easily, without a more complicated structure. This air conditioner is equipped with: a refrigerant circuit that includes a compressor (3), an indoor heat exchanger (7), a throttle device (5), and an outdoor heat exchanger (4); a receiver (13) that stores the refrigerant; and a connecting pipe (14) connecting the refrigerant circuit and the receiver (13). This air conditioner is characterized in that one end of the connecting pipe (14) is connected to an inlet/outlet (15) of the receiver (13) and the other end is connected to an area in the refrigerant circuit wherein at least a portion of the high-pressure refrigerant discharged from the compressor (3) during the cooling operation exists in the liquid phase, with the receiver (13) being provided so as to be capable of exchanging heat with a pipe (12) in which refrigerant flows from the indoor heat exchange (7) to the compressor (3) during the cooling operation.</p> |
