When you turn on the air conditioner for the first time, you should blow it empty first. When turning on the refrigeration, you can turn the air outlet of the air conditioner up and blow the cold air upwards as much as possible, so as to achieve natural convection circulation in the car and improve the refrigeration efficiency.

How to turn on the car air conditioner to have the best cooling effect?

1. In fact, if you want to lower the temperature inside the car as soon as possible, the correct thing to do is to open the doors and windows, keep the inside and outside of the car ventilated, so that the temperature inside the car is as close as possible to the outside temperature, and then close the doors and windows and start the air conditioner, so that the cooling effect of the air conditioner will be better. The internal and external cycles should be used alternately. When driving in summer, many people like to drive an internal cycle for a long time.

2. When turning on the air conditioner, the external circulation of the air conditioner should be turned on first. Because the interior temperature of a car can be as high as 60 or 70 degrees Celsius after being exposed to the sun. You should first open the door and window for ventilation, and then turn on the external circulation of the air conditioner. When the temperature inside and outside the car is similar, close the window and turn on the inner circulation.

3. Insert the key into the keyhole. Turn the key to start the vehicle. Turn on the car air conditioner knob, which can be adjusted to 4 or 4 gears. The higher the gear, the greater the air output. Adjust the air conditioner to the refrigeration part, that is, the blue area shown in the figure below. The lower it is, the stronger the refrigeration effect will be.

How to turn on the air conditioning and refrigeration in the car

How does car air conditioner cool

Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator and compresses it into high-temperature and high-pressure gas to discharge the compressor. Heat dissipation process: high-temperature and high-pressure overheated refrigerant gas enters the condenser. Due to the reduction of pressure and temperature, the refrigerant gas condenses into liquid and discharges a large amount of heat.

Compression process: The compressor compresses the low-temperature and low-pressure gaseous refrigerant on the low-pressure side of the evaporator into a high-temperature gasic refrigerant and sends it to the condenser for cooling.

Generally, the blue button on the left side of the car is air conditioning, the red button is heating, and the middle is moderate temperature. The way to turn on the car air conditioner is to turn on the fan, press the A/C button, and adjust the temperature to the low temperature zone. In addition, the button in the middle controls the air volume, and the button on the right is the adjustable mode.
