What does the air conditioning button of the car do? Which ones are more practical?

Do you really know all the buttons of the car air conditioner? Let's take a look with Bian Xiao!

First of all, there are two forms of air conditioning in the car: automatic air conditioning and manual air conditioning. The simplest way to judge is to check whether there is an' automatic' button in the air conditioning control area. If there is an automatic air conditioner, it is a manual air conditioner. There is a difference between the two ways of adjustment. The adjustment mode of manual air conditioner is relatively simple and intuitive, generally knob type, which can not accurately adjust the temperature and is difficult to get started. Therefore, we will focus on the various key functions of automatic air conditioning.

A/C key

Air conditioning key is the key of air compressor, which can be understood as the key of refrigeration. Because the air cooling in the car is realized by the air compressor, press this button, the air compressor will start to work when the light is on, and then the air conditioner will have a cooling effect, otherwise the natural wind blowing in the car will be outside.

Maximum air conditioning key

Some cars with automatic air conditioning will have this button. After this button is pressed, both the air compressor and the blower will produce maximum output, and the temperature inside the car will be quickly adjusted to the set value. When this function is turned on, the air conditioning system in the car will run at full load, and the air volume of the fan is also the largest, so the car will be noisy, which is not suitable for being turned on all the time, and will have a certain impact on fuel economy. Generally, it can be used when the car needs rapid cooling when it is just started.

Internal circulation and external circulation

These two keys are keys to switch the inner and outer loops. The corresponding key light is on, which is the corresponding mode, but some cars may only have one internal circulation key. In this case, the internal circulation light is on, which is the internal circulation mode, and the light is off, which is the external circulation mode. The internal circulation mode is faster, more effective and more fuel-efficient, and the external circulation mode can keep the air freshness in the car well, provided that the external air quality is good. We just need to switch according to the situation.

Automatic key point

This is the automatic air conditioning button. When this function is turned on, the air conditioner will automatically adjust the wind speed and air volume according to the temperature value you set, so as to keep the temperature inside the car within the set value, achieving the effect of constant temperature without frequent operation.

Synchronous zone temperature control button

This button is the air conditioning zone control key. If your car has district air conditioning, then there will be this button. Under normal circumstances, air conditioners are uniformly tuned. When we press this button, the unified adjustment can be released. At this time, the air conditioning temperature of the main and passenger seats can be adjusted independently, which is the key to partition operation. In addition to SYNC, there are DUAL, MONO and ZONE, which all mean partition control.

Temperature and wind speed regulation

These buttons are very common, I believe everyone knows how to use them. Temperature adjustment buttons are generally indicated by blue and red arrows, or by TEMP+/-, and wind speed adjustment buttons are generally indicated by small fans. In addition to buttons, some cars also use knobs to adjust.

Air conditioning wind direction control

The button is visually displayed and consists of an arrow pointing to the head and an arrow pointing to the foot. The arrow pointing to the head means blowing up; Point to the feet, that is, down, where the feet are placed, there will be wind; If you have two arrows, the wind will blow up and down.

Front and rear windshield defogging

Finally, these two function keys for windshield defogging generally appear in the air conditioning control area. The fan-shaped symbol is front windshield defogging, and the square symbol is rear glass defogging.
