Under normal circumstances, air conditioning filter can be filtered from the outside into the inside of the air, so that the cleanliness of the air to improve, to ensure the health of passengers in the car. It is very important to maintain the cleanliness of the air conditioner filter if the vehicle is often through the dusty road. Temperatures in the winter cold, some car owners closed the window, only open the inner circulation is not open air conditioning, master said that this approach is not correct, driving for a long time will cause the in car air pollution, bring certain risks to human health.
Automotive air conditioning system in use process, the air will flow in the blower, refrigerating system evaporation tank, heating system of the small water tank and the air duct. As long as the air conditioning system blower or the air intake mode selection in the indoor cycle, regardless of whether or not the use of refrigeration equipment, air will enter the above system. These air will accumulate in the surface of the device on the surface of the above devices a lot of dust, water, bacteria and other dirt. Tianchang in the course of time, the breeding of bacteria, odor, and will cause damage and allergic reactions to human respiratory system and skin, directly affect the occupant's health, and air-conditioning system itself also appear cause refrigeration effect is bad and a small amount of wind and other fault.
The air conditioner filter is designed to avoid the phenomenon, which can effectively filter the dust, pollen and bacteria in the air and prevent the pollution to the air conditioning system. Automotive air conditioner filter with activated carbon coating can also kill bacteria in the air and inhibit the regeneration of the bacteria. But in the process of using the air conditioning system, with the passage of time, dust and bacteria will be gradually accumulated in the air conditioning filter, when it reaches a certain degree after the air conditioning system will also appear a series of faults. Need regular maintenance, in order to maintain a good quality of air conditioning. Therefore, regular cleaning, regular replacement of air conditioning filter is a must to do the work.
