In summer, car air conditioners have become a necessary companion for car owners when they travel. However, the air conditioners in the car that may not be used for a long time will blow out unpleasant smell or feel that the cooling effect is much worse than before. Some of them may be caused by the incorrect use of air conditioning by the owner. Is your car air conditioning right?

1. Is the air outlet of the air conditioner upward or downward?

The principle of hot air rising and cold air sinking. We should also grasp this rule when turning on the air conditioner in the car. When turning on the air conditioner, the air outlet should be upward, and when turning on the warm air, the air outlet should be downward.

2. Frequently clean and regularly replace the air conditioning filter element

Many car owners often wash the car, but do not pay attention to the maintenance of the car. In summer, there are frequent rainstorms and the weather is humid. If the air conditioning filter element is not cleaned in time, it will produce peculiar smell and musty smell in the car.

3. Occasionally open strong wind gear

During the use of the air conditioner, occasionally open the maximum air volume to blow out the residual floating dust in the air duct.

4. How to use internal and external circulation

Internal circulation, external circulation, silly can not distinguish clearly! When the car is hot, we need to use the external circulation to release the hot air in the car, and then turn on the cold air when the temperature drops almost, and turn on the internal circulation at the same time.

5. Air conditioning also needs rest

Many friends will turn on the air conditioner all the way when running at high speed. In fact, this will make the condenser pressure of the air conditioner too high. Turning on the air conditioner for a long time will seriously damage the refrigeration system. It is recommended that you open the window for ventilation for a while, which is good for your health and the car.

6. Fluoride can not be underestimated

Don't you feel cool when the air conditioner is turned to the maximum? It is likely that the lack of fluorine affects the heat dissipation of the system, resulting in the air conditioner not cooling.

7. Turn on the air conditioner every week

In summer, the air conditioner is turned on almost every day. What about winter? Try to turn on the cold air 3-4 times a month for 5 minutes each time, which can effectively prevent the aging of the evaporator and compressor.
