Automobile air conditioning filter installed in reverse what will be the impact

The filter element of automobile air conditioning wants to know the structure of filter element first before installation, the requirement of installation space and wind direction, follow Chen hair hong small make up to understand.

We need to find out why there are directional requirements for installing air conditioning filters.

The structure of the filter element of automobile air conditioning is hierarchical. The density of each layer of filter material is different, and the pore diameter is different. The purpose of this design is to increase the dust capacity of the filter element.

As the name implies, dust capacity is the maximum dust capacity that the filter element can hold. During the use of the filter element, dust will accumulate in the filter material. When the dust accumulates to the limit of the filter material, the filter element will become blocked and fail.

Therefore, the outer layer of the air conditioning filter element, that is, the side facing the outside air, is a coarse filter layer, and the inner layer, that is, the side facing the air duct of the air conditioning system, is a fine filter layer.

When installed in the right direction, the dust will first pass through the coarse filter layer, with the larger particles remaining in this layer and the smaller particles entering the more medial filter layer, so that the filter element can contain more dust. It's like when we go to a show and everyone is seated, so we can make sure the seats in the theater are filled and as many people as possible.

When the installation direction is reversed, the dust will first pass through the fine filter layer. At this point, particles of all sizes will be isolated in this layer. The result is that the fine filter layer quickly becomes saturated while the coarse filter layer does not play any role.

In addition, some high quality filter elements will add some function layers inside the coarse filter layer, if installed in reverse, these functions will not be able to play properly.
