1. Turn on the air conditioner immediately after getting in the car.
In the hot summer, the refrigerated truck is exposed to the sun, and the temperature inside the truck is as high as 40-60 degrees Celsius. Many car owners often turn on the air conditioner immediately after getting in the car and use it for a long time. This can cause damage to the vehicle, and some car owners open the car windows while using the air conditioner, which not only wastes energy, but also has poor results. The best way is that the owner has just entered the car, if the temperature inside the car is high, you can open the window for ventilation, reduce the temperature inside the car through the airflow inside and outside the car, and then turn on the air conditioner to cool down.
2. Open the inner loop to the end
The internal circulation refrigeration effect is good and fuel-saving, so some owners only use the air-conditioning internal circulation system. In fact, such a long period of time will cause the car's air quality to become worse and worse, and the oxygen content is also getting lower and lower. It will not only cause great harm to the respiratory system of the car owner, but also cause dizziness and hypoxia of the driver and passengers in some extreme cases. Therefore, the correct use of air conditioning systems is very inappropriate.
3. The air conditioner is dormant
The air conditioner is easy to breed many molds, which affects the air quality in the car. If it is not used for a period of time, "mildew" may appear and emit a foul smell. Therefore, when the weather is good, the car can be driven to the outdoor open area, the doors and windows are all opened, and the air conditioner in the car is turned on in the external circulation state, and the air volume is maximum, which lasts for 10 to 20 minutes. If there is fungus, you can only replace the air conditioner filter in time to clean the air duct of the vehicle air conditioner. Compared with the "sunglasses" function of the car film, the function of the air-conditioning filter is more similar to the car mask, and it also needs to be cleaned and replaced in time.
4. The air conditioner is not clean
Car air conditioners should remember to clean them regularly. If it is not cleaned for a long time, it will cause great harm to human health over time.
5. Turn on the air conditioner and stop to rest
Parking, closing windows, or turning on the air conditioner to rest, the engine will slow down, gasoline will burn incompletely, and harmful substances such as carbon monoxide will be produced. Coupled with closed windows, the body's exhaled carbon dioxide will increase, and oxygen will decrease, causing headaches, chest tightness, or electric vehicles. asphyxia. The enclosed space of the carriage is easy to enter the carriage through the outer circulation, which increases carbon monoxide and brings potential safety hazards.
In order to avoid tragedies, you must first be aware of safety, and secondly, you must develop good habits such as not closing the windows to make room for air circulation.
