Claims

[Scope of utility model registration request]

A compressor with a low-pressure container inside, an indoor/outdoor heat exchanger that condenses and evaporates the refrigerant, a decompression mechanism, an accumulator that separates liquid refrigerant into gas and liquid, and a refrigerant that reversibly flows into both heat exchangers. In a heat pump type air conditioner, which has a four-way switching valve for passing through the air, and which forms a cooling cycle and a heating cycle by switching the four-way switching valve, the oil sump of the compressor and the suction pipe of the accumulator to the compressor. A heat pump type air conditioner that connects the upper part of the oil return hole with a pressure equalizing pipe.
