How to use car air conditioner

Don't turn on the air conditioner after the car is exposed to the sun in summer. You have to open four doors first, and then turn on the air conditioner after 5 minutes of natural wind.

The correct steps should be: first, open the doors and windows. You can use a fan to ventilate first. In two or three minutes, you can get in and start the car. Don't close the window in a hurry. First, turn on the external circulation of the air conditioner. When the temperature inside and outside the car is almost the same, close the window and start the internal circulation. This can avoid the overload when the engine is started, and at the same time, the air conditioning compressor can quickly enter the best working state, so it is the best choice.

Tips Try not to turn on the air conditioner when driving at low speed:

Some people turn on the air conditioner as soon as they get on the bus, whether driving at low speed or high speed, in order to keep cool. If the air conditioner is still used when driving at a low speed, the engine will artificially run at a high speed when encountering traffic jams, which will reduce the service life of the engine and the air conditioner compressor. Therefore, it is best not to turn on the air conditioner when driving at low speed.

Don't drive too long

Using air conditioner for a long time will make the condenser pressure too high and cause losses to the refrigeration system. So, if the temperature inside the car is comfortable, turn off the air conditioner for a while and let it have a rest.
