The low-pressure gas sucked by the compressor is compressed into high-temperature and high-pressure gas by the compressor, and the high-temperature gas raises the water temperature through the heat exchanger, and at the same time, the high-temperature gas will condense into liquid. The liquid enters the evaporator and evaporates. After passing through the evaporator, it becomes low-pressure and low-temperature gas, which is sucked and compressed by the compressor again.
When heating, there is a component called four-way valve, which makes the refrigerant flow in the condenser and evaporator in the opposite direction to that during refrigeration, so when heating, cold air is blown to the outside and hot air is blown to the room.
In fact, it is the principle that junior high school physics has learned that heat is discharged when liquefied (from gas to liquid) and heat is absorbed when vaporized (from liquid to gas).
Extended data
The compressor compresses the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser (outdoor unit) for heat dissipation, and turns it into liquid refrigerant at normal temperature and high pressure, so the outdoor unit blows out hot air.
Then enter the capillary and enter the evaporator (indoor unit). Because the space suddenly increases and the pressure decreases after the refrigerant reaches the evaporator from the capillary, the liquid refrigerant will vaporize and become a low-temperature gaseous refrigerant, thus absorbing a lot of heat, and the evaporator will become cold. The fan of the indoor unit will blow out indoor air from the evaporator, so the indoor unit will blow out cold air.
Water vapor in the air will condense into water droplets when it meets a cold evaporator and flow out along the water pipe, which is why air conditioners produce water.
The water in the water tank is continuously pumped out by the circulating water pump and evenly sprayed on the evaporation filter layer through the water distribution system. Outdoor hot air enters the evaporative cooling medium and fully exchanges heat with the water in the evaporative cooling medium CELdek (a special honeycomb filter layer, a Swedish high-tech patented product).
The cool and clean air cooled by water evaporation and heat absorption is pressurized by a low-noise fan and sent into the room, so that the hot air in the room is discharged outside, thus achieving the purpose of indoor temperature reduction.
