It's getting hotter and hotter. When you stop, do you turn off the fire first or turn off the air conditioner first? Many car owners often think of turning off the air-conditioning after the fire goes out. In fact, this practice is very harmful!
Wrong Practice: Turn off the fire first and then turn off the air conditioner
It is harmful to the engine to turn off the air-conditioner first, because the engine will start with the air-conditioning load when the vehicle starts next time. Such high load will damage the engine.
Best practice: Turn off a few minutes before arriving at the destination, which can turn on the natural wind, make the temperature in the air-conditioning pipeline rise again, eliminate the temperature difference with the outside world, so as to keep the air-conditioning system relatively dry and avoid mildew reproduction. Also, the air conditioner should be turned on after the vehicle starts for two or three minutes and the engine is lubricated.
Many people are not very familiar with the use of air conditioning. Once the operation is wrong, it will not only affect the performance and life of the air conditioning system, but also damage the health of the people in the car.
1. Is the outlet moved at will?
Some drivers do not pay attention to adjusting the direction of air-conditioning when they turn on air-conditioning, which affects the air-conditioning effect. Because of the physical principle of hot air rising and cold air sinking, it is suggested that the air outlet should be properly upward when the driver turns on the air conditioner and downward when he turns on the heating.
2. How long does the air conditioner last?
Many drivers often turn on the air conditioner when they get on the bus, and long-term use of the car air conditioner will greatly increase the pressure of the condenser, thus greatly increasing the loss of the refrigeration system. Therefore, the use of air-conditioning time should not be too long, when the car temperature reaches a more comfortable temperature, the air-conditioning can be properly shut down for a while, and then re-open the air-conditioning later.
3. Drive the inner cycle immediately in summer?
In hot summer, many car owners are accustomed to turn on the inner cycle of air conditioning as soon as they get into the car, thinking that this can make the temperature in the car drop faster. This is wrong, because the temperature inside the car is higher than that outside, so the effect is not good. Because the internal circulation is the circulation of air in the car, the oxygen content in the car decreases gradually. When the gasoline in the cylinder burns unsafely, the carbon monoxide and carbon dioxide produced may leak into the car, resulting in worse and worse air in the car. Therefore, it is suggested that the owner should turn on the inner cycle for a while and then switch to the outer cycle to start the ventilation.
