Notes for the use of automobile air conditioners

1,, observe the water temperature of the engine after turning on the air conditioner for a period of time. If the water temperature is high, it may be caused by the surface of the condenser being too dirty (such as adhesion of willow lin, dust, etc.), the electronic fan does not work, the pressure controller does not work, etc. Of.

2. The air conditioner filter should be replaced regularly, because there is a lot of sand and dust, which will stain the filter, which is easy to breed bacteria and make the air conditioner smell moldy, so it is best to replace it once a year after the season. In addition, the condenser should also be cleaned regularly, and the water tank should be removed so that the cleaning can be thorough.

3. When turning on the new air conditioner, the external circulation must be used first. After the temperature drops, you can switch to the in-car circulation. Note that the air ducts inside and outside the vehicle are connected to each other.Whether the air conditioning system is turned on or not, the air will continue to flow in and out. If the fan is turned on at this time, the air exchange and circulation speed will accelerate.

4. When the motor vehicle air conditioner is in use, the motor vehicle must be operated first, otherwise the refrigeration compressor of the car will not work, and the air conditioner cannot be used. During the operation period of the air conditioner, the internal circulation system and the external circulation are replaced to be applied to ensure the air index in the vehicle.

What is the function of various parts of car air conditioner?

1. The functions of the components of automobile air conditioning are as follows: automobile air conditioning compressor: it is the heart of the automobile refrigeration system and the power source that promotes the continuous circulation of refrigerant in the automobile refrigeration system. Exhaust pipeline: the high-pressure pipeline connecting the compressor and condenser. The refrigerant flows from the compressor to the condenser.

2. Automobile air conditioning controller is a kind of control device of automobile air conditioning equipment. Adjust the automobile air conditioning system, with the functions of refrigeration, ventilation and defrosting. All equipment is firmly installed, the control device and control mechanism rotate flexibly, operate freely, and the performance is safe and reliable.

3. Car air conditionerThe refrigeration system is composed of compressors, condensers, liquid storage dryers, expansion valves, evaporators and other main components, as well as air conditioning pipes and refrigerants.

What is the reason why the car air conditioner does not cool

1. Insufficient refrigerant. The most common reason why the air conditioner does not cool is the lack of refrigerant, which may also be caused by the leakage of refrigerant. If it is insufficient, it should be replenished in time, but if there is leakage, it should be repaired in time. Too much refrigerant.

2. The reasons why the air conditioner of the car does not cool are as follows: insufficient or too little refrigerant. And the shortage or too little refrigerant is likely to be a trace leakage of refrigerant in the refrigeration system. Too much refrigerant may also cause the air conditioner not to cool down.Because the proportion of refrigerant in the air conditioning system is required.

3. Insufficient refrigerant: car air conditioning usually adds refrigerant once every 2 to 3 years, and the loss of refrigerant is mainly leakage. If your car has a defect in free adjustment, and it will start to have defects after adding refrigerant for a period of time, then you should pay attention to it.

Car air conditioning button function illustration

The air volume button can also be called the wind speed button. The icon is a small "fan", which selects the appropriate air volume by turning the button.

A/C button A/C button is the switch of the air conditioner compressor. Only when the compressor is turned on can the air conditioner have the ability to cool. Otherwise, only the natural wind from the outside world blows in the car, which cannot meet the refrigeration needs of the passengers in the car in summer.

Defogging is located in the central control button area, with defogging function buttons on the front windshield and rear windshield. Press the corresponding switch to turn on the defogging function. The warm air is turned on. As long as you turn up the temperature, you can turn on the warm air.

What is the key function of the car air conditioner? There are three most basic adjustments in the car air conditioner, which are air volume, temperature and wind direction. First of all, the air volume is the air volume button, which can also be called the wind speed button. The icon is a small "fan", and the appropriate air volume is selected by turning the button.
