The reason why there is a peculiar smell in the car when the air conditioner is turned on in summer is that the main components of the car air conditioning system are all inside a plastic shell, including the blower, evaporation box, distribution box, air conditioning water tank, etc. In winter, the warm air blown from our air conditioner comes through the air conditioner water tank.
The solutions to the peculiar smell of the air conditioner are as follows:
1. Clean the air duct
Use air conditioning duct cleaning agent, as long as you park the car in a place with good air environment After the location, turn on the external circulation switch and turn the air conditioner to the natural ventilation position, then spray the cleaning agent evenly from the air supply outlet into the air duct. After a few minutes, open the window and turn on the air conditioner for ventilation.
2. Replace the air-conditioning filter element
Generally, the service life of the air-conditioning filter element is 30,000 kilometers or one year. If you often drive on dirt roads or roads with poor air quality, you need to shorten the replacement timely. cycle. Especially for people who often smoke in the car, they should pay more attention to changing the air conditioning filter element frequently. Because the air conditioning filter element will accumulate some foreign matter during the filtration process, which will produce odor over time, so pay attention to its cleaning and replacement.
3. Bask in the sun
Drive the car under the sun, put the air conditioning system on the warm wind block, then turn the air volume to the maximum, and bask in the sun with the doors and windows fully open. In ten minutes, ultraviolet rays are used to disinfect the interior of the car, and hot air is allowed to thoroughly circulate the dirty air in the air supply duct. However, this only applies to cars with less severe odor.
Most car air conditioning filters are under the front windshield of the car. Blow the removed filter clean with high-pressure air, and then put it back in place after drying in the sun for a few hours. That’s it. If the contamination is serious, then it needs to be replaced.
So the best way to solve the odor of air conditioners is to pay attention to the cleaning of the air conditioner at ordinary times, so that stains have no place to hide, then the occurrence of odors will be greatly reduced.
After being out of service for nearly half a year, some car air conditioners may have leaked refrigerant and need to be replenished. When you go to the repair shop for maintenance, don't forget to remind the repairman to clean the evaporator and air conditioning filter element. Their blockage will affect the cooling effect and emit odor during use. At the same time, checking whether the cooling effect of the air conditioner is the same as the factory specification is a must-do item when maintaining the air conditioner. It is also an important step in diagnosing whether the air conditioner is "healthy".
