It should be used in combination with internal and external circulation.

Before getting into the car to use the air conditioner in the summer, first circulate the air in the car so that the hot air in the car can be discharged. The main method is to open the door or minimize the glass on the same side. At this time, do not open the glass on the other side. By opening and closing the door, the hot air in the car can be circulated and discharged.

Another method is to open the four-door windows or open the diagonal windows. When the vehicle is driving, the hot air will circulate faster. After the temperature inside and outside the car is similar, close the window, turn on the AC cooling function of the air conditioner, and circulate the inside and outside. Select the external circulation state. The temperature adjustment can select the lowest temperature, which can speed up the temperature balance in the car. After the temperature drops to the required temperature, close the outer circulation and open the inner circulation.

Precautions for car air conditioning in summer

1. The air conditioner temperature should not be too low.

Choosing the appropriate air conditioning temperature is the first step in air conditioning maintenance. Due to the hot weather, many car owners like to adjust the temperature too low, which will affect their health. Under normal circumstances, the difference between the temperature inside the cabin and the outside temperature should be 5°C to 6°C, that is, the optimal temperature of the air conditioner is 18°C to 25°C.

2. Control the direction of the air outlet

Principle of the air outlet of car air conditioner: when turning on the air conditioner, turn the air outlet upward, and when turning on the heating, turn the air outlet downward.
