Summer car air conditioning health care: Additives can help you. The car air conditioning system is often neglected by most car owners for maintenance. Generally speaking, after about five years of operation, the car air conditioning system will gradually age, the cooling efficiency will decrease, and the airflow will not be strong. Manufacturers and 4S stores often organize car owners to carry out inspection and maintenance work on car air conditioners. However, if you want to do some maintenance work yourself, then some car air conditioner repair (maintenance) additives available on the market will be your good helper.
Working principle: These car air conditioning additive products can enhance the compressor seal, reduce wear, lower noise, and improve the working efficiency of the compressor. They help to significantly reduce the friction and increase the seal inside the air conditioner, enhancing the cooling effect, making the air conditioner and various functional components inside the car work more efficiently, beautify the car, and thereby extend the service life of the car air conditioner.
In the car accessories market, there are also kits of air conditioning system additives priced at around 400 yuan. Through this product, car owners can themselves carry out a series of processes such as maintaining, cleaning, and enhancing the cooling of the car air conditioner.
Main effects:
1. After adding the repair agent, the temperature of the air conditioning outlet can be reduced by 2~5℃, improving the cooling effect of the air conditioner;
2. Reduce the friction resistance of the air conditioner compression, reduce the load of the compressor by 15~23%, reduce wear, and extend the service life of the air conditioner twice;
3. Eliminate abnormal noises caused by worn compressors;
4. Save 10% fuel and reduce car usage costs.
Master's tips: Some car owners add Freon refrigerant in the car. When it's very hot in summer, too much Freon refrigerant can cause high pressure beyond limits, making the engine produce thunder-like vibrations, sometimes even causing the engine to overheat. Repair masters say that this is mainly due to the small engine power and partial equipment aging. At this time, turning on the air conditioner makes the engine overloaded and unable to drive the air conditioner compressor; if the air conditioner continues to be forced to use, the car damage will worsen, and in severe cases, it may cause the car to self-ignite. Therefore, he suggests using relevant car air conditioner additive products appropriately in such situations.

It can store excess cold air in the cabin and use it when the cold air is insufficient. It can effectively overcome the uneven cold and heat conditions caused by different driving speeds of current vehicle air conditioners. It is reported that this cold-storing car air conditioner saves about 25% electricity compared to regular vehicle air conditioners.
According to the introduction, traditional vehicle air conditioners waste a lot of cold air when the car is running at high speed, and the release of cold air is not uniform. The power is large when the car speed is fast, and small when the car speed is slow, like an oil-eating "tiger". The special cold-storing material developed by Nanjing University releases cold air as soon as the cold storage device is started when the car stops or runs slowly.
