Terex TEXREX accessories share with you why my car still smells like this after replacing the air conditioning filter?

I believe many people have encountered the problem of air conditioner odor. Generally speaking, new cars rarely appear when they are bought. However, after a summer or a few years, it is easy to smell. Especially for cars with poor maintenance, when the air conditioner is turned on in summer, the smell is absolutely disastrous.

Why does the air out of the air conditioner smell? How to solve the air conditioner odor? In today's truck encyclopedia, let's talk about why my car still smells like this after replacing the air conditioner filter? In the previous truck encyclopedia, we introduced that the air conditioning system is composed of fan, compressor, condenser, expansion valve and evaporator. Whether it is internal circulation or external circulation, the air entering the cab will pass through the fan – air conditioning filter – evaporation box – air outlet.

Therefore, the odor producing parts are only the above-mentioned parts. Of course, if you turn on or off the air conditioner, there will be odor. Please check whether there are other odor sources in your engine compartment or your driving environment.

Under normal circumstances, the only place where odor may occur is the air conditioning filter element. The reason is that the air conditioner filter element is responsible for filtering the dust and impurities in the air. Over the years, various pollutants have accumulated on the air conditioner filter element, ranging from dust, hair to insect bodies.

For a long time, this is the place where peculiar smell is most likely to occur. Therefore, replacing the filter element of the air conditioner Terex TEXREX accessories on time can eliminate the peculiar smell brought by the air conditioner.

If the air conditioner filter element is not replaced on time, the dust and impurities that are nowhere to be contained will gradually fill the air conditioner inlet and slowly accumulate on the evaporation tank behind the air filter element. When the air conditioner is used, the wet condensate on the evaporation box will wet the dust and impurities, which is easy to mildew and cause odor. At this stage, if the filter element of the air conditioner is replaced, it will be difficult to eliminate the odor. Only by cleaning the evaporation tank can the odor be completely eliminated.

In addition, a small part of the odor comes from the inlet. When the external circulation is turned on, the air conditioner absorbs air from the outside of the vehicle. If the vehicle (flat car generally does not have this problem) often stops under a tree, it will lead to the accumulation of dust on the leaves outside the air inlet, and there will also be an odor. When the internal circulation is turned on, the air conditioner inspires air from the car. If the car environment is dirty, the dirty air is always circulating inside, and there will also be obvious odor. At the same time, the carbon dioxide gradually rises, making the driver sleepy. Therefore, we suggest that you try to open the external circulation to meet the supply of fresh oxygen.

● Postscript

In addition to replacing the filter element of the air conditioner on time, the use of the air conditioner is also very skilful. The air conditioner is on in summer. The dry summer in the north is better. The humid summer in the south will produce a lot of condensate. The truck encyclopedia suggests that when you are about to arrive at the destination, you should turn off the air conditioner in advance. At this time, you should only ventilate to let the air dry the water on the evaporation tank, so as to reduce the possibility of mildew. Do you remember today's truck encyclopedia?
