Claims

[Scope of utility model registration request]

A heat pump type comprising a compressor, an indoor heat exchanger, a throttling means, an outdoor heat exchanger, and a hot gas bypass circuit that introduces hot gas discharged from the compressor to the outdoor heat exchanger during defrost operation. In the air conditioner, a plurality of accumulators are interposed in the suction piping of the compressor, and the suction piping on the upstream side of the accumulator closest to the compressor among the plurality of accumulators is connected to the discharge piping of the compressor. A heat pump type air conditioner characterized in that a bypass pipe is provided, and a capillary tube and an on-off valve that is opened during heating operation and defrosting operation are interposed in the bypass pipe.
