APPARATUS FOR IMPROVING SUPER HEATING RATE OF REFRIGERANTS IN HEAT PUMP AIR-CONDITIONER

摘要

The present invention compresses a low-temperature, low-pressure refrigerant in gas state that is sucked in through the intake temperature, the compressor discharge through the discharge port in a gaseous state of high pressure, connected to the compressor and piping outside air heat exchange with the indoor heat exchanger and the outdoor, which of the refrigerant on the side of the heat exchanger and the heater pump air conditioner which has a passage for respectively connecting the discharge port and the suction port of the compressor the group the indoor heat exchanger and the outdoor heat exchanger comprises a four-way valve is switched to change the flow of heat-refrigerant exchanger an apparatus for improving the degree of superheat, that a connecting pipe connecting the outdoor heat exchanger and said four-way valve so that by the heat generated by the compressor to remove the liquid component of the refrigerant flowing into the compressor wraps around the outside of the compressor It characterized.
