What is the problem of automobile air conditioning compressor locking?

Now there is an idle switch not only at home, but also in the car. The key of automobile air conditioning system is composed of compressor, condenser, throttle valve (expansion device) and evaporator. Automobile air compressor is the heart of automobile air refrigeration system and the power source of refrigerant circulation in the system. The structure of condenser is similar to that of evaporator. Basically, a row of bent pipes are covered with metal sheets to dissipate heat and can exchange heat with the outside world. Its principle is similar to that of engine radiator. Next, let's take a look at the locking of the automobile air compressor.

1. The compressor is only responsible for air conditioning and compression, not refrigeration. No leakage, no noise and sufficient pressure are qualified products.

Second, the original compressor has been damaged, that is, the original air conditioning system is in doubt. The causes of air-conditioning compressor failure are: (1) poor heat dissipation, too many kinds of snow, affecting high pressure, causing the compressor to drag again, causing pressure and connecting rod parts to be damaged or burned out; (2) When the automobile is used for a long time, the aging of the compressor will produce organic carbon, which will lead to pipeline blockage, or the drying bottle fails to filter water, which will lead to icing and blockage; (3) The pipeline installation configuration is not fixed and swings for a long time, resulting in air leakage during hoisting.

3. Precautions before replacing the compressor: 1. When replacing a new compressor, please clean the air conditioning pipeline, cooling net and evaporator. Clean the pipelines in the system separately, fill the pipeline condenser with cleaning agent, soak it in the evaporator for about 20 minutes, and then rinse off the cleaning agent and dirt with high-pressure nitrogen. 2. Clean or replace the expansion valve. The drying bottle is a pipeline filter and must be replaced. Please choose pure cold coal.

Air compressor is the heart of refrigeration system and the power source of refrigerant circulating in the system. The basic working principle of refrigeration system includes four processes: compression, condensation, throttling and evaporation. A compressor compresses a low-temperature and low-pressure refrigerant into a high-temperature and high-pressure gaseous refrigerant, a condenser turns the refrigerant into a medium-temperature and high-pressure liquid refrigerant, a throttling expansion device turns it into a low-temperature and low-pressure liquid refrigerant, and finally an evaporator turns it into a low-temperature and low-pressure gaseous refrigerant. Evaporation absorbs a large range of heat around, and then sucks the low-temperature and low-pressure refrigerant into the air compressor for the next refrigeration cycle, so as to achieve the refrigeration effect.

In hot weather, drivers should check and maintain their cars in all directions, especially compressors, condensers, evaporators, air conditioning pipes and circuits. After confirming that there is no problem, the air conditioning system should be sterilized and deodorized to eliminate the fungi and molds bred in the air conditioning system and keep the air inside the car fresh and clean. At the same time, in order to reduce solar radiation, you can stick a layer of solar film on the window glass, which can effectively block and reflect the scorching sun.

Don't turn the temperature too low when the car is empty. Especially when the outdoor temperature is high, if the indoor temperature is adjusted too low, it will consume more oil, which is easy for both drivers and passengers. Ldquo automobile air disease regulation &; Rdquo, this is about health. In most cases, the temperature difference between inside and outside the car is within 10 degrees. At the same time, it is best not to smoke in the air-conditioned car. After all, the internal volume of the car is limited, and the smoke exhaust function of most cars is not necessarily too strong. When the travel jam occurs during driving, it is not necessary to increase the engine speed just to improve the air conditioning efficiency, so as not to affect the service life of the engine and the air conditioning compressor.

Some drivers, especially those who drive for the leader at one o'clock, are used to sleeping in the car with the empty switch on when parking, thinking it is very comfortable. I think this kind of living habit is not good. Due to the poor ventilation in the car, the safest way to rest is to drive the car to the shade, turn off the air switch, open the window and take a rest.

There are also many drivers who get into cars with high temperature under the scorching sun and use the empty switch in time. I thought the temperature in the carriage would drop rapidly. I think this is also a misunderstanding. Due to the greenhouse effect, the temperature inside the car parked in the hot sun is much higher than that outside the car. Therefore, it is necessary to open the window and let the air inside and outside the carriage exchange heat, and the temperature inside the carriage will soon drop to the same temperature as outside. At this time, close the window and adjust it to be empty according to the opening situation.

Automobile air conditioning calibration is very important equipment, and maintenance is essential. In recent years, with the development of domestic economy, manufacturing industry has gradually occupied a key position in China. China is the main production base of automobile air compressors in the world. With the increase of automobile demand and the improvement of automobile manufacturing capacity, the automobile air compressor industry has also made great progress. I hope that friends can help us understand what problems exist in the locking of automobile air compressor after reading the introduction of automobile system.
