1, air conditioning filter element. The function of air conditioning filter element is very simple, mainly to filter the air from air conditioning and prevent impurities from entering the carriage. However, if the air conditioning filter element is seriously polluted, it will not only not protect the environment of the carriage, but will cause secondary pollution to the air in the carriage.
2. Evaporation box. When the evaporator is working in refrigeration, it will produce moisture on the surface when it meets the hot air outside, and it is also easy to attach impurities such as dust and flying insects, which will ferment, mold and breed bacteria in a humid environment for a long time. When the air conditioner is turned on again, the wind will blow these harmful substances into the car mercilessly.
Extended data:
The air-conditioning filter element is generally replaced once a year, but it is also feasible to replace it once every three months when the air conditioner is used frequently or the external environment is extremely poor. If the air-conditioning filter element is dirty, you can simply blow it, but avoid cleaning it many times, otherwise the filtering effect of the air-conditioning filter element will be obviously reduced.
The smell on the evaporation box is difficult to deal with. Usually I go to a professional maintenance company to clean the air conditioner. When cleaning, I spray a special air conditioner cleaner on the blower when I turn on the air conditioner.
