How many kilometers is it better to clean the car air conditioner? Why?

How often the car air conditioner is cleaned depends on the specific driving environment. Cities with good air need to be cleaned once a year, and it is best to clean once a month from May to June if possible. If it is in a city with poor air environment, or the air environment of a car is poor, this cycle needs to be shortened as appropriate, and it is best to clean the air conditioning filter once every 3-4 months. It can effectively clean the bacteria and dust in the air-conditioning pipeline, make the air in the air-conditioning pipeline clean, and will not make drivers and passengers feel uncomfortable. Evaporate the bacteria and dust in the box to keep the air quality and environment of the cab.

Don't think that the air conditioner won't turn on and the filter screen of the air conditioner won't be dirty, because the air conditioner won't turn on the default external circulation, and the air pressure generated by the filtering speed of the air conditioner will still filter the air in the car. The principle of automobile air conditioning refrigeration, heating and heating is switched to the past cold air and hot air through the damper, and only the wind can smell the source of the smell. The blower blows wind into the car through the inlet. There is a filter element at the inlet of the blower. As long as the filter element is not damaged, it does not need to be cleaned normally. Replace the filter element in the air conditioner.

If the filter element is damaged, there will be dirt and odor on the evaporator of the air conditioning box. Cleaning will be more troublesome at this time. The instrument panel air conditioning box needs to be removed for cleaning. Unknown conditions such as abnormal sound may occur during the recovery process. This method is not recommended. When the hot car stops, the warm air can dry the wet surface on the evaporator, which is wrong and has no effect. According to the driving environment of vehicles, there is no problem in coastal cities once a year, and it is recommended to do so once a quarter. Generally speaking, cleaning is simple. You can do it yourself, find the location of the air conditioning filter, and take out the high-pressure air to blow back. If you feel trouble, let the maintenance owner help you deal with it every time you do maintenance, which generally will not increase the cost.
