As long as the AC light is on, it means that the air-conditioning compressor is started. After the compressor is started in this case, what we want is not its refrigeration function, but its dehumidification function. So even in winter, you can turn on the AC when the temperature in the car is set to heating. At this time, the compressor only has dehumidification function, and what comes out is dry heating

1. Rainy days in summer: due to the rain, it is not possible to open windows for convective demisting. The following operations should be followed: external circulation mode → wind force mode → adjust to lower temperature → outlet front wind mode → turn on the air conditioner. Of course, if the weather is cold, it is more appropriate to turn on the air conditioner first, and then turn on the heating after the frost and fog disperse. Turning on the air conditioner can quickly reduce the temperature of the front windshield and make the frost fog lose the condition of condensation. Turning on the air conditioner again is to make the car owner not feel cold.

2. Spring and Autumn: it's not too cold, but when there is fog in the car, you don't need to turn on the air conditioner, you don't need to turn on the hot air, it's very simple, open the window for convection.

3. Winter: Method 1: after the hot car, turn on the ventilator, adjust to the external circulation, align the air outlet with the front windshield, and blow directly with hot air for 10 minutes. But the effect is relatively slow, the advantages do not increase energy consumption. Method 2: also the most effective method! Hot car > confirm that the water temperature is at normal working temperature > external circulation mode > wind power > adjust to temperature > outlet front wind mode > turn on the air conditioner.

PS: remind, if the water temperature gauge doesn't reach the middle scale in winter, don't turn on the warm air demister, it's not good for the engine! You can turn the cold and hot air knob to the cold air position, turn it to the external circulation position, turn the position knob to the demisting position, turn on the fan, and set the minimum gear. Wait until the temperature of the water temperature gauge rises to the normal working temperature, then adjust the cold air to the hot air, and adjust the knob to the normal position. This not only protects the engine, but also can remove fog. In other ways, adjust the air outlet of the air conditioner to the windshield, turn on the air conditioner switch, and let the compressor work for dehumidification. However, if the temperature control knob is set to the cold windshield at this time, the people in the car will definitely be too cold to bear, so the temperature knob can be placed in the warm air position to achieve the purpose of both demisting and heating.

The operation of automatic air conditioning is very easy. Turn on the automatic air conditioning and turn the mode switch to the demisting gear. At this time, the air conditioning will automatically switch to external circulation, and the fresh air outside will enter the cab, and the demisting will begin.

If it is a manual air conditioner, first of all, the wind direction switch should be adjusted to the demisting gear, the external circulation should be started to let fresh air blow in, and the compressor and wind speed should be adjusted to speed up the demisting speed. If you feel that the demisting of the side glass is not fast enough, close the two central air outlets to make the air flow of the two air outlets quickly blow away the fog, or open the window properly to speed up the demisting.

In addition, special mist eliminator can be used. Spray the special glass cleaning antifogging agent on the car glass and wipe it clean; While removing the glass dirt, it can also form a thin protective film on the glass, which can effectively prevent the fog formed by condensation of water vapor on the glass. Generally, spraying once can last for one day.
