What brand is good for air conditioning and heating?

1. When the household air conditioner is heating, the refrigerant of the outdoor unit is pressurized by the compressor to become high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (in this case, the condenser), condenses, liquefies, releases heat, becomes liquid, and at the same time heats the indoor air, thus achieving the ultimate goal of increasing the indoor temperature.

2. After the liquid refrigerant is decompressed by the throttling device, it enters the heat exchanger (evaporator at this time) of the outdoor unit, evaporates and gasifies to absorb heat and becomes gas, and at the same time absorbs the heat of outdoor air (outdoor air becomes cold).

3. Refrigerant turned into gas enters the compressor again and starts the next cycle. Based on the above process, the heating of air conditioner is realized.
