First, check whether the refrigerant is sufficient, which can be measured by sensing the temperature difference between the inlet and outlet pipes of the dryer, or by checking the manifold pressure gauge.
Secondly, clean the air outlet and the dust and dirt in the cab frequently. This not only helps the beauty of the car, but also benefits the health of the driver and passengers.
Third, regularly check whether the liquid level of the refrigerant in the air-conditioning system is normal. There are several ways to check the liquid level, but the most common and easiest way is to use the peephole of the dryer.
Fourth, check whether the car ac compressor belt is in good condition. If the surface of the belt is bright on the contact side of the pulley groove, and there is a "squeaking" noise when starting the air conditioner, it means that the belt slips seriously and the belt and pulley should be replaced; if the belt is too loose, adjust it, otherwise it will cause poor cooling of the air conditioning system.
Fifth, check the air-conditioning system hoses and pipe joints for oil stains. If any leakage is found, consult the maintenance department for solutions in time.
In addition, when the car air conditioner is used for the first time in a season, it is best to sterilize and deodorize the air conditioner system. This is because the air conditioner system will breed fungi and mold for a long time "off". It not only makes the air emit an unpleasant musty smell, but also affects the car. The health of the personnel inside is harmful. This work can be carried out in a repair shop, or you can purchase a special spray for sterilization and deodorization by yourself.
