How to use the button of the air conditioner in the car?

The air conditioning button is the switch of the air conditioning compressor. Only when the compressor is turned on can the air conditioner have refrigeration capacity, otherwise only the natural wind from outside blows into the car, which can't meet the refrigeration demand of passengers in the car in summer.

2. Maximum air conditioning key

This function only appears on some automatic air-conditioning models. After MAX is pressed, the air-conditioning compressor and blower will reach the set temperature as soon as possible with the maximum output. After the MAX function is started, the air conditioner in the car will run at full load, and the fan will have the largest air volume and noise, but this function is very practical for riders who need to get a comfortable temperature as soon as possible after starting.

3. Defogging of front windshield and rear windshield

This fan-shaped sign has an upward curved arrow and the previous word added. When it is on, it is the defogging function of the front windshield, and when it is on, it is the defogging function of the rear windshield.

4, air conditioning wind direction control

The arrow points to the head, that is, blows on it; Pointing at the foot means blowing down. There are two arrows, that is, the wind blows in two directions. There is also a foot-blowing mist, which beginners can easily forget.

5, inner ring, outer ring button

Internal circulation means opening the air conditioner with the door closed, while external circulation means opening the door to blow the air conditioner. The refrigeration effect of internal circulation will be much faster and more fuel-efficient, but external circulation can ensure the freshness of the air inside the car, provided that the air outside the car is of good quality.

5, automatic key

AUTO means automatic. Turn on this function, and the air conditioner in the car will automatically adjust the wind speed according to your preset temperature. For example, if it is appropriate to set the indoor temperature at 20 degrees in advance, if the indoor temperature is higher than the set temperature, the system will automatically adjust to the maximum wind speed for rapid cooling, and if the indoor temperature drops to the set temperature later, the air conditioner will automatically reduce the wind speed.

6. Double control keys

"DUAL" is the air conditioning partition control key. When this key is pressed, the indicator light will light up. At this time, you can set the air conditioning temperature of the front seat and the passenger seat, and turn off this key after adjusting to the required temperature. The automatic air conditioner will adjust the temperature according to the set value.

1. Precautions for the use of automobile air conditioners?

1. When using the air conditioner in summer, you should first open the window of the parked vehicle, turn the blower to the maximum position, so that the air inside the vehicle can form convection, and exhaust the hot air outside the vehicle in time before closing the window, so as to achieve the purpose of rapid cooling.

2. When parking, turn off the air conditioner first, and then turn off the engine to avoid increasing the starting load.

3. Turn on the internal circulation when using the air conditioner, so that the cooling effect is the best.

4. Avoid using the air conditioner for a long time when the vehicle is parked, so as to avoid the deterioration of the air quality inside the vehicle and affect the health.

Second, the misunderstanding of the use of automobile air conditioning

1, the air outlet direction of air conditioner can be adjusted at will.

Some car owners do not pay attention to adjusting the blowing direction of air conditioner when using air conditioner, which is not conducive to achieving the best effect of air conditioner. According to the physical principle of air circulation, cold air will sink and form convection with hot air. Therefore, when the air conditioner is turned on, the air outlet will go up, so that the cold and hot air in the car will convection and the cooling speed will increase.

The temperature of air conditioner is very low.

Many car owners like to keep the temperature inside their cars at a very low level after being "baked" by the scorching sun outside. Don't turn the air conditioner too low and the wind speed too low. In general, the temperature difference between the inside and outside of an automatic constant temperature air conditioner should not exceed 65438 00℃. For non-constant temperature air conditioning, you can set the temperature to the lowest and the wind speed to the maximum. When you feel cold, you can raise the temperature a little and lower the wind speed by one step.

3. Open the internal circulation for a long time

Because the internal circulation is the circulation of air in the closed space of the car, the oxygen content in the car will continue to decrease. If the gasoline in the cylinder is not completely burned, unburned carbon monoxide in the engine may leak into the car, so the air quality in the car will become worse and worse, even harmful to the human body. Therefore, it is necessary to open the internal circulation for a while, and then open the external circulation for a while to let fresh air enter the carriage. It's a truth that you can't sleep in the car with internal circulation on.

4. Enter the car in summer and immediately start the internal circulation.

When the car is parked in the hot summer sun, the temperature inside the car may be as high as 60~70℃. At this time, the doors and windows should be opened first, and the fan can be used for ventilation first. After the hot air is exhausted for two or three minutes, you can sit in and start the car. Don't close the window in a hurry. Turn on the external circulation of the air conditioner first, and then close the window to start the internal circulation when the temperature inside and outside the car is almost the same.

5. Clean the air conditioner only when its performance is poor.

Some novices always wait until the air conditioner doesn't work before thinking of cleaning it. The correct way is to replace the air conditioning filter regularly. The air conditioning system mainly cleans the air conditioning ventilation pipeline, carries out pressure detection and cleans the evaporation box.
