Do You Know Construction Of Automobile Air-Conditioning System?

The automobile air-conditioning system is a device for cooling, heating, ventilating and purifying the air in the cabin. It can provide passengers with a comfortable riding environment, reduce the driver's fatigue strength, and improve driving safety.

It is actually very simple to judge whether the air-conditioning system is working well. If you find that the air-conditioning has poor cooling, small air volume, or simply does not cool, you need to check whether each component is operating normally and whether it is lacking in condensate. The condensate must be added according to the model on the manual of the vehicle. These can be done in a professional store. For our car owners, it is worth noting that the air conditioner filter element needs to be replaced regularly. Generally, driving in urban road conditions, we need to replace the air conditioner filter element for about 3,000 kilometers. This will not only make the intake system cleaner, but also avoid the air conditioner. A clogged filter element causes a decrease in cooling capacity.

In summer, the temperature difference between the inside and outside of the car is relatively large. When entering the car, it is not advisable to immediately adjust the temperature of the air conditioner to be too low. You can use a large amount of natural wind to blow away the heat in the car first, then do not close all the windows and turn on the air conditioner. After the body gradually adapts, adjust the air conditioner to the required temperature and close the window. In this way, our body will not cause discomfort due to the sudden temperature drop outside.

The temperature of the air conditioner is not as low as possible. The most comfortable temperature of the human body is around 23 degrees Celsius. In the afternoon when the sun is full in summer, the air conditioner should not be too low, which can resist the sun in summer and ensure the human body’s location. The ambient temperature is not too low, which leads to "air conditioning disease", but also responds to the national call for energy saving and emission reduction, low carbon and environmental protection.

When the air conditioner is turned on, passengers are advised not to smoke in the car. When the air conditioner is turned on, the air in the car circulates in a relatively closed environment. First, the smoke is not easy to escape. Second, the tiny particles in the smoke will adhere to the air conditioner. The air filter element causes a long-term odor in the car.

Regular professional air conditioning system cleaning and sterilization and deodorization maintenance

1. Before checking the temperature of the high and low pressure pipes, the air conditioner should be set to the maximum cooling, the maximum air volume, the direct blowing position, the air circulation, and the A/C switch turned on. According to experience, the temperature of the air outlet is about 5 degrees Celsius.

2. Hold up the hood to confirm that the electronic fan is running at the same time, and the compressor is also running. If it is not running, loosen the protective cover of the high-pressure pipe and find a sharp tool to gently press the high-pressure exhaust thimble to see if there is a strong refrigerant overflow. If there is no strong overflow of refrigerant, please carefully check whether the joints of the air-conditioning pipe have oil stains. If there is any leak point, the air-conditioning system may prove to be a waste of time. This is inevitable. The owner is required to fully understand the maintenance leak. Finally, remember to screw on the protective cover.

3. Touch the high-pressure pipe and the low-pressure pipe with your hands and feel their temperature carefully. When the refrigeration system is working properly, the normal temperature of the high-pressure tube is about 50 to 60 degrees Celsius, that is, you can firmly hold the hand for about 30 seconds, and you can't hold it any longer. The temperature of the low-pressure pipe is about 5 to 6 degrees Celsius, that is, you can feel the iceman with your hand.
