What should I do if the car air conditioner blows out the stench?

Evaporation box (evaporator) is the most likely to produce odor in common air conditioning structures, and evaporation box is an important part of air conditioning refrigeration. The "refrigerant" passes through the evaporation box, and the evaporation box absorbs heat by exchanging heat with the outside air to achieve the refrigeration effect. A small amount of moisture and dust may be attached to the evaporation box, which will be moldy over time, and then produce odor.

The air-conditioning filter element mainly filters air, and the air will reach the evaporator after passing through the air-conditioning filter element, so the air-conditioning filter element plays the first protective role. In addition to filtering dust, the air-conditioning filter element will also absorb odor, and it will also produce odor if the air-conditioning filter element is not changed for a long time.

Air conditioning duct is a ventilation duct, which is easy to accumulate dust, but it is often ignored by people. The smell of air conditioners also has a lot to do with the use environment. For example, when the air quality is not very good, the filtration system of the air conditioner itself will be inefficient.

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.

(3) the method to solve the odor of evaporation box

It is difficult to deal with this smell. It is usually recommended that you go to a professional maintenance company to clean the air conditioner. When cleaning, spray the special air conditioner cleaning agent on the blower with the air conditioner turned on.
