The sign of heating is the sun. When you press the "Mode" button many times, the icon on the display screen of the air conditioner remote controller will appear in the shape of the sun, indicating that the air conditioner is currently in a heating state, and the air blown by the air conditioner is hot air. Then adjust and press the temperature adjustment button to set the temperature at the appropriate temperature.

Air conditioning heating principle:
The low-pressure gas sucked by the compressor is compressed into high-temperature and high-pressure gas through the compressor, and the high-temperature gas increases the temperature of water through the heat exchanger, and at the same time, the high-temperature gas is condensed into liquid. The liquid evaporates after entering the evaporator. After passing through the evaporator, the liquid becomes a low-pressure and low-temperature gas. The cryogenic gas is sucked into the compressor again for compression.
In this way, the circulating water on this side of the air conditioner becomes hot water of about 45-55 degrees. Hot water is transported to the room that needs heating through pipes, and fan coil units are installed in the room to realize the exchange heating of hot water and air.
The air conditioner remote controller is a triangle arrow of heating sun, hot air, cooling snow, dehumidifying rain and circulating air.
1, heating principle
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.
In this way, the circulating water on the air conditioning side will become hot water of about 45-55 degrees. The hot water is sent to the room that needs heating through the pipeline, and the room is equipped with a fan coil unit, so that the hot water can exchange heat with the air to achieve the purpose of heating.
2. Refrigeration principle
Liquid vaporization refrigeration uses the heat absorption of liquid vaporization and the heat release of condensation to realize refrigeration. Liquid evaporates to form steam. When the liquid (refrigerant) is in a closed container, there is no other gas except the vapor generated by the liquid and the liquid itself, and the liquid and the vapor will reach equilibrium under a certain pressure. At this time, the gas is called saturated steam, the pressure is called saturated pressure, and the temperature is called saturated temperature.
