Heat pump heating uses the compression condenser of the refrigeration system to heat the indoor air. When the air conditioner is working in cooling mode, the low-pressure refrigerant liquid evaporates and absorbs heat in the evaporator, while the high-temperature and high-pressure refrigerant releases heat and condenses in the condenser. Heat pump heating is achieved by electromagnetic reversing, which swaps the position of the suction and exhaust pipes of the refrigeration system. The indoor coil of the evaporator in the original cooling mode becomes the condenser in the heating mode, so that the refrigeration system absorbs heat outdoors and releases heat indoors to achieve the purpose of heating.

In fact, the air conditioner is controlled according to the thermal expansion and contraction of the medium. The indoor part is contraction, and the outdoor part is thermal expansion. How does it expand? It is to compress the medium through the compressor to do work, which will generate a lot of heat, which is thermal expansion, and then it is transmitted to a much larger space through a capillary tube. In this way, the pressure of the medium is much lower at once, which is the heat absorption of contraction, and the heat in the room is exchanged into cold gas at once.

Set the appropriate temperature. When cooling, do not set the temperature too low. If the room temperature is adjusted to 26-27 degrees Celsius, the cooling load can be reduced by more than 8%. Practice has shown that for people who sit quietly or do light labor, if the room temperature is kept at 28-29 degrees Celsius and the relative humidity is kept at 50-60%, people will not feel stuffy or sweat, which should be within the comfortable range. When people sleep, their metabolism decreases by 30-50%. If the air conditioner is set to the sleep switch position and the temperature is set 2 degrees Celsius higher, it can save 20% of electricity; in winter, if the temperature is set 2 degrees Celsius lower, it can also save 10% of electricity.
