Claims

[Scope of utility model registration request]

In order from the discharge side 2 of the compressor 1, a first gas pipe 5, a first indoor heat exchanger 6, a second indoor heat exchanger 7, and an expansion mechanism 9 which has a smaller diameter than the first gas pipe 5 and whose opening degree can be adjusted freely.
interposed liquid pipes 8, 10, outdoor heat exchanger 11,
While connecting the second gas pipe 12, the second gas pipe 1
2 is connected to the suction side 3 of the compressor 1 to constitute a refrigerant circulation circuit, and a pressure reducing mechanism 13 and an on-off valve 14 are interposed between the indoor heat exchangers 6 and 7, which are connected in parallel to each other. In the air conditioner, the first gas pipe 5 and the liquid pipes 8, 10 are connected to the first gas pipe 5 and the liquid pipes 8, 10.
connection switching mechanism 20 that can switch the connection state with 10;
The first gas pipe 5 communicates with the discharge side 2 of the compressor 1 and the first indoor heat exchanger 6, and the liquid pipes 8 and 10 communicate with the second indoor heat exchanger 6.
During the heating operation state in which the indoor heat exchanger 7 and the outdoor heat exchanger 11 are communicated, the refrigerant discharged from the compressor 1 is transferred from the first gas pipe 5 to the second indoor heat exchanger 7 via the liquid pipe 8. At the same time, the refrigerant from the first indoor heat exchanger 6 is supplied to the outdoor heat exchanger 11 via the first gas pipe 5 and the liquid pipe 10 so as to be switchable to a dry operation state. An air conditioner characterized by:
