How to use automobile air conditioner reasonably?

Proper use of the air conditioner in the car can prolong the service life of the air conditioner. The following are the skills of using the air conditioner in the car.

1, the steps to turn on the air conditioner should be correct. In hot summer, the car is sultry. Many people are used to turning on the air conditioner as soon as they get on the bus. We should start the vehicle first, wait for the engine to stabilize, and then turn on the air conditioner in a few minutes. You must turn on the AC key to turn on the air conditioner. In cold winter, you don't need to turn on the AC key, because the warm air only uses the heat generated when the automobile engine works, and you don't need to start the air conditioner compressor.

2. Air volume control of the air conditioner does not mean that the air conditioner is set to the lowest gear in order to save electricity. After a while, the air conditioner turned up and blew away the dust in the air conditioner. It is best to adjust the blowing direction of the air conditioner above the syncline, so that cold air can circulate from top to bottom; It is also wrong to say that the air volume of the air conditioner is adjusted to the lowest level and the fuel consumption is small. In fact, when the blower is working, the energy consumption is very small for the power of the vehicle. According to the actual test, the air volume of the air conditioner is adjusted to the maximum gear and the minimum gear, and the difference in fuel consumption is not obvious. Don't worry about the fuel consumption of the air conditioner at the maximum gear.

3. Switch the internal circulation correctly. When it is a long distance in summer, the air conditioner is turned on for a long time. In the state of internal circulation, the air will not circulate inside and outside, and the refrigeration effect is better. In the state of external circulation, the high-temperature air outside is sucked in and blown out after being cooled by the evaporator, so the outlet air temperature is relatively high and the refrigeration effect is poor. It is suggested to start the internal circulation for half an hour, and then start the external circulation for 5 minutes, so as to avoid the excessive concentration of carbon dioxide in the car caused by long-term circulation, which will lead to the driver's inattention and drowsiness, and prevent accidents.
