Problems solved by technology
[0002] Generally, when the air conditioner is cooling, the refrigerant throttled by the throttling element directly enters the indoor heat exchanger for heat exchange. Since the throttled refrigerant is mixed with a part of gaseous refrigerant, it enters the indoor heat exchanger for heat exchange. The gaseous refrigerant in the heater not only affects the heat exchange effect of the indoor heat exchanger, but also increases the compression power consumption of the compressor and reduces the energy efficiency ratio of the compressor, thus affecting the energy efficiency level of the air conditioner
