problem

1. After a period of use, car air conditioners often smell a smell similar to mold and smoke;

2. When cooling or heating, the air blown out from the air outlet is not fresh, and if people stay in the car for a long time, they will feel uncomfortable in the nasal cavity and trachea;

3. These are all caused by the odor generated by car air conditioning. So, why does car air conditioning produce odor?

reason

1. When the air conditioning system is running, the water vapor in the air forms condensate on the surface of the condenser evaporator of the air conditioner, and a portion of the water will remain in the evaporator and air conditioning pipelines after the air conditioner is turned off. These moisture, combined with microorganisms and pollutants in the air, become a breeding ground for mold, Aspergillus, Penicillium, LP bacteria, and mites in humid, warm, and dark air conditioning systems.

2. Nicotine produced by drivers and passengers smoking in the car

3. The odor emitted by rubber, plastic, and leather inside the car

4. Smoke, dust, and exhaust gases from the outside air enter the car.

These odors not only cause breathing difficulties and weakened immunity, but also cause irritability, lower judgment and memory, and in severe cases, can lead to traffic accidents. The bacteria, molds, and viruses blown out from the air conditioning pipes constantly threaten the health of drivers and passengers, so the cleaning and maintenance of car air conditioning systems is very important.
