Generally, if the refrigeration of the air conditioner is poor, the first thought is that the air conditioner is short of fluorine and needs to be added. Or the compressor is damaged. But the air conditioning filter element is ignored. This article will explain the function of air conditioning filter element, maintenance and the consequences of not replacing it in time. Since different brands of excavators have different requirements for air conditioning filter elements, the explanation of maintenance is only for reference.
1. Function of air conditioning filter element
1) It can provide fresh air for the excavator cab. Avoid the driver from inhaling harmful gases, which can effectively sterilize and deodorize.
2) It can isolate dust, pollen and other impurities in the air.
3) It can absorb moisture, soot, ozone, odor, carbon oxides, etc. in the air, and can strongly and permanently absorb moisture.
2. Maintenance of air conditioning filter element
1) If you feel that the air blown out of the air conditioner is significantly less than before, the air conditioner filter element may be blocked. First, clean the filter element and replace it if necessary.
2) The frequency of cleaning and replacement depends on the working conditions and the surrounding environment. For example, in the environment of heavy dust or excessive humidity in the region, the time for replacing the air conditioning filter element should be shortened.
3) The air conditioning filter element must be replaced once a year under normal use. Do not delay the replacement time for other reasons.
3. Consequences of not replacing the air conditioning filter element in time
If the air conditioning filter element is not replaced in time, it will be blocked for a long time. Excavator drivers will often feel dizzy and nauseated for no reason, and even induce respiratory diseases in serious cases. Moreover, if the filter element is not replaced for a long time, the cooling effect of the air conditioner will become worse and worse. In serious cases, it will cause damage to the components of the air conditioning system, or even no refrigeration.
