The odor of air conditioning is generally caused by the problems of filter element, air duct and evaporation box. Generally speaking, when the dust in these three places breeds bacteria or mold, it will produce odor. Let's talk about the specific cleaning steps of the filter element and air duct: 1. Cleaning steps of filter element 1 Prepare MK62 10 filter element and tools, and remove the outer package of the filter element. 2. Pull open the adhesive tape and start to remove the screws. 3. Remove the old filter element and clean it with foam. After cleaning, install the air conditioner. The reason for the odor is 1. Air conditioning filter is too dirty; 2. The evaporation box is too dirty: when the air flows through the radiator of the evaporation box during the operation of the automobile air conditioner, the impurities are filtered out of the air by the radiator, and then discharged together with the condensed water through the air conditioner drain pipe. If impurities and condensed water in the air stay on the radiator surface of the evaporator, fresh air will produce odor when passing through the radiator. 3. The evaporation box is moldy: during the operation of the air conditioner, the water in the air forms condensed water on the surface of the evaporation box, and part of the water is discharged, but after the air conditioner stops, part of the water remains on the surface of the evaporator. When moisture combines with dust in the air, it is easy to produce mold and eventually produce the smell of air conditioning. There are dead mice, dead insects and other rotten and smelly things in the air duct and pipeline. @20 19
