Do you turn off the engine or air conditioner first when driving? Many drivers usually want to turn off the air conditioner after turning off the engine. In fact, such practices do great harm! Air conditioning installation of construction machinery.
Wrong behavior: turn off the engine first and then turn off the air conditioner
It is harmful to the engine to turn off the air conditioner after the engine is turned off. As the engine will start with the load of the air conditioner the next time the car starts, the load for a long time will damage the engine.
Better practice: close it more than ten minutes before arriving at the station, so that you can turn on the blowing, warm the temperature in the air conditioning pipeline, remove the temperature difference with the outside, thus maintaining the relative dryness of the air conditioning system software and preventing the breeding of Aspergillus flavus. And the air conditioner should also be turned on after the car starts for two or three minutes and the engine is moistened.
Many people do not know how to operate the car's air conditioner very well. Once the actual operation is incorrect, it will not only endanger the characteristics and service life of the air conditioning system software, but also continue to endanger the physical and mental health of the staff in the car!
Does the vent rotate freely?
Some drivers do not pay attention to the regulation of the air frequency when they turn on the air conditioner, thereby harming the actual effect of the air conditioner. Because of the physical principle that warm air rises and strong cold air moves downward, it is suggested that the driver should turn the air vent up moderately when turning on the air conditioner, and turn the air vent down moderately when turning on the radiator.
Is the use time of air conditioner unique?
Many drivers usually turn on the air conditioner as soon as they enter the vehicle. However, the long-term application of the car air conditioner will greatly increase the working pressure of the cooler, thus greatly increasing the consumption of the refrigeration unit. Therefore, the air conditioner should not be used for too long. When the temperature in the car is relatively comfortable, the air conditioner can be properly turned off for a while, and then turned on again.

Start the internal circulation immediately after entering the car in summer?
In the hot summer, many car buyers habitually turn on the internal circulation of the air conditioner as soon as they get into the car, and feel that it can reduce the temperature in the car body faster. That's not correct. Because the temperature inside the car is higher than that outside the window, the actual effect is not very good.
Because the internal circulation is the circulation system of gas in the car, the oxygen content in the car is slowly reduced. When the car gasoline in the cylinder is not safe to ignite, the carbon monoxide and carbon dioxide will flow into the car box, causing the gas in the car to become worse and worse. Therefore, it is suggested that the buyer should open the internal circulation for a while and then switch to the external circulation when applying the air conditioner to start the ventilation effect.
Sleep with the air conditioner on after parking
In order to eliminate fatigue, some people park their cars on the road, close the windows and doors, turn on the air conditioner, and "enjoy" the comfort of cooling. In fact, it is a very risky thing. When the engine is working, such as the gasoline in the cylinder is not completely ignited, it will cause carbon monoxide with high concentration, which will lead to poisoning and even death. Therefore, it is not suitable to sleep in the car with the air conditioner on to prevent risks.
The air conditioner is always on with less exhaust air volume
Most car buyers mistakenly believe that the air conditioner will consume more fuel when it is turned to a higher gear, so they will try to turn on a smaller exhaust volume. In fact, in the whole process of application, air conditioners usually inhale a certain amount of dust, which leads to stains. If they stay for a long time, they will become moldy. If a small amount of wind is used for a long time, it is impossible to blow out the scale in the air conditioners, but it will harm your physical and mental health. Therefore, it is necessary to turn the air conditioner to a higher gear every time, which can reasonably avoid dust accumulation in about ten minutes.
Smoking in the car with the air conditioner on
Some people turn on the air conditioner and smoke in the car when they are parked or waiting. In fact, that is harmful to the health of the people in the car. Because the windows and doors are closed tightly, the smoke cannot be discharged, which will certainly irritate your eyes and respiratory tract. Therefore, parking and opening the air conditioner are harmful, and smoking is also harmful to your physical and mental health. Remember to adjust the natural ventilation of the air conditioner to the "exhaust" position. Air conditioning installation of construction machinery.
