One of the most annoying things about driving in the summer is that opening the air conditioner has a musty smell. Whether it is the South or the North, this is an unavoidable trouble. In the north, the sand is big, the winter is warm, the air conditioning is turned on in summer, the whole vehicle needs to be cleaned frequently, the south is wet, and the air conditioner may not be known. What should I do?

1, do a good job of air-conditioning cleaning All the owners of the car will do regular cleaning to the car, the outside is always sparkling, but how many people noticed that the car air-conditioning is cleaned?

If the automobile air conditioning system has not been cleaned for a long time, the aphids and microorganisms accumulated therein may also cause serious diseases such as pharyngitis and bronchitis. The air conditioner filter is usually cleaned every 5,000 km or 3 months, and the air conditioner filter is replaced every 20,000 km or 12 months. In addition to cleaning and replacing air conditioning filters, air conditioning ducts and evaporation boxes also need to be thoroughly cleaned on a regular basis.

2. Wrong use of air conditioners can also cause troubles. For example, do not stay in an air-conditioned vehicle in the summer. Pay attention to air circulation and air convection. The air-conditioning temperature cannot be set too low, generally about 25°C.

After sun exposure, open the door first and use external circulation to dissipate heat. After the temperature drops, the cooling effect is better in the internal circulation mode. The internal circulation time is long, and the indoor air is dirty. Remember to open the window and breathe often.

At low speed, turn off the air conditioner temporarily, and do not turn on the air conditioner for too long. Prolonged use of automobile air conditioning will cause excessive pressure on the condenser, which will cause loss to the refrigeration system and affect its life.

Turn off the air conditioner a few minutes before parking. A few minutes before parking, turn off the air-conditioning, turn on the natural wind later, increase the temperature inside the air-conditioning duct before stopping, and eliminate the temperature difference from the outside, so as to keep the air-conditioning system relatively dry.
