The use, maintenance and maintenance of automobile air conditioners

1. Choose the right air conditioner temperature. Of course in summer, many people like to keep the temperature very low. As everyone knows, when the temperature is adjusted too low, it will affect the health of the body, so the temperature adjustment of the air conditioner must be appropriate. The most suitable temperature for the human body is 20°C to 25°C. If it exceeds 28°C, people will feel stuffy. And below 14 ℃, people will feel cold. Therefore, the air conditioner should control the temperature in the car between 18 ℃ and 25 ℃, and the temperature is too low to easily make people sick.

2. Start the inner cycle immediately after entering the car in summer. When the car is parked in the hot sun for a long time, some car owners like to turn on the air conditioner and turn on the internal circulation as soon as the car is started, thinking that this can make the temperature in the car drop faster. But because the temperature inside the car is higher than the temperature outside the car, this will not work well. When you first enter the car, you should open the windows for ventilation and open the external circulation to exhaust the hot air. After the temperature in the cabin drops, switch to internal circulation.

3. Everyone knows to use the air conditioner in a fully enclosed state. The same is true for car air conditioners. If the doors and windows are not closed tightly during use, the cooling effect will be poor, and fuel will be wasted.

4. The direction of the air outlet can be adjusted at will. Some car owners do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the best effect of the air conditioner. According to the principle that cold air sinks and hot air rises, the correct approach should be to turn the air outlet upwards when turning on the air conditioner, and turn the air outlet downwards when turning on the heating.

5. Turn on the air conditioner for a long time. Some car owners often keep the air conditioner on after getting in the car, but using the air conditioner for a long time will cause the condenser pressure to be too high, which will cause losses to the refrigeration system, because the air conditioner is a heavy burden on the engine, and the engine itself is a heat source. body, especially in hot weather. Some small-displacement cars even have water boiling phenomenon in this case, which affects driving and reduces the efficiency of air conditioning. Therefore, each time you use the air conditioner should not be too long. If the temperature in the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while.

6. Do not smoke in the car with the air conditioner on. Due to smoking in the car, the smoke cannot be discharged at once, which stimulates the eyes and respiratory system, which is not good for health.

7. Do not rest or sleep for a long time in a parked car with an air conditioner on. Because the car is well sealed, when the car is stopped, the ventilation in the car is poor. If the air conditioner is turned on to rest or sleep at this time, it is very likely that the carbon monoxide gas discharged from the engine will leak into the car and cause personnel poisoning or even death.

8. Try not to use the air conditioner when driving at low speed. When driving in traffic jams, do not run the engine at a higher speed in order to improve the efficiency of the air conditioner, because doing so will adversely affect the service life of the engine and the air conditioner compressor.

9. Turn off the flame first and then turn off the air conditioner. Some car owners often remember to turn off the air conditioner after turning off the engine, which is harmful to the engine, because when the vehicle is started next time, the engine will start with the load of the air conditioner, and such a high load will damage the engine. Therefore, the air conditioner should be turned off first and then turned off after each stop, and the air conditioner should be turned on after the vehicle has been started for two or three minutes and the engine has been lubricated.
