Since the reform and opening up, with the rapid development of our country’s economy, people’s requirements for the quality of life have become higher and higher, especially in the automobile industry. An important guarantee for comfort and safety when riding in a car.
Attention: Generally, car air conditioners are used in the initial stage, especially in the first three years. The effect is very good. The cooling and heating are rapid, and people feel comfortable in the car. This has a lot to do with the performance of the air conditioner. However, due to lack of care for proper use and maintenance in the later period, the air-conditioning effect is often poor. Therefore, we must properly maintain the car air conditioner, which can not only increase the service life of the air conditioner, but also keep the air conditioner system in good working condition. Especially in the hot summer, the maintenance and overhaul of air conditioners have become more important for car lovers. Here are a few simple techniques to achieve this goal.

Don't turn on the air conditioner just after starting, and turn off the air conditioner in time when the engine is turned off. In the hot summer, when the car is exposed to the sun for a long time, the temperature inside the car rises sharply. Therefore, most car owners will turn on the air conditioner as soon as the car starts, and adjust the cold air to Z. But sometimes you will find that the air conditioner is turned on to Z, but the air conditioner is delayed. At this time, many car owners think that the air conditioner is malfunctioning, so they went to the 4S shop to check the condensate and clean it, but after checking for a long time, everything was normal. In fact, the correct way is to first roll down the glass windows on both sides after getting in the car, adjust to the external circulation air intake mode, and then adjust the cooling degree of the air conditioner to Z, so that the hot air in the cab can be forced out first. . After about 3 minutes, the hot air in the car gradually dissipates, then close the windows, switch the air conditioner's outer circulation to the inner circulation mode, and adjust the temperature of the air conditioner moderately, so that the cooling effect of the air conditioner is obviously better than that of turning on the air conditioner as soon as it enters the cabin. It's much better, and it can also reduce the load on car air conditioners.
Car air conditioners should not adjust the temperature too low, nor should they turn on the air conditioner for a long time. It is not advisable to adjust the temperature of automobile air conditioners too low, otherwise it is easy to produce liquid hammer and damage the compressor. Some car owners often turn on the air conditioner after getting in the car. Long-term use of the air conditioner will cause excessive pressure on the condenser, which will cause loss of the refrigeration system. Therefore, each time the air conditioner is used should not be too long. If the temperature in the car has reached At a comfortable temperature, you can turn off the air conditioner and turn it back on after a while.
Intermittent use of air conditioning. Some car owners often turn on the air conditioner after getting in the car. Long-term use of the air conditioner will cause excessive pressure on the condenser, which will cause loss of the refrigeration system. Therefore, each time the air conditioner is used should not be too long. If the temperature in the car has reached At a comfortable temperature, you can turn off the air conditioner and turn it back on after a while.
are used alternately inside and outside. Many car owners believe that keeping the internal circulation mode on is good for rapid cooling. This is a good view, but it will also cause harm to our human body. Because the air-conditioning internal circulation mode is the circulation of air in the enclosed space of the car, the oxygen content in the car will continue to drop, and if the gasoline in the cylinder is not completely burned, the unburned carbon monoxide of the engine may leak into the car. The air quality in the car will get worse and worse, and it may even cause harm to the human body. Therefore, the inner circulation should be opened for a while, and the outer circulation should be opened for a while to allow fresh air to enter the compartment. This is also the reason why you cannot sleep in the car with the inner loop. Aluminum alloy casting
Correctly adjust the direction of the air outlet. Some car owners do not pay attention to adjusting the blowing direction of the air conditioner when using the air conditioner, which is not conducive to the best effect of the air conditioner. According to the principle of sinking cold air and rising hot air, the correct approach should be to set the air outlet upward when turning on the air conditioner, and turn the air outlet downward when turning on the heater.
With the deterioration of the environment, especially the environment during the driving of the car is also relatively harsh, so the maintenance of the car air conditioner is particularly important. Maintenance should be carried out from the following aspects.
Clean and sterilize regularly.
Regularly clean or replace the filter element of the air conditioner.
Clean the condenser and evaporator regularly. Planetary disc, swash plate
Regularly check the pressure of the refrigerant.
Choose the right refrigerant.
In short, the secret to the "longevity" of car air conditioners is prevention. Correct use and regular maintenance, and the formation of good habits will make the air conditioner system "eternally youthful."
