Recently, Changsha's continuous rain and snow days have made it more troublesome for everyone to travel by car. In addition to paying attention to maintaining a safe driving speed, it is equally important to have a good view and a comfortable driving environment. When many people drive in winter, they encounter many problems with the warm air in the car.
Huang Qiang, who has a lot of "driving age", has encountered this problem, and when he recently opened the warm air in the car, he always encountered the fogging of the front retainer of the window. Whenever the glass fogged, he continued to choose the "old way", turning on the cold air conditioner in the car and blowing the glass for a while.
It turned out that Huang Qiang, like many car friends, had entered the same misunderstanding, that is, adhering to the knowledge taught by the "old drivers" of that year, and adjusting the air conditioning knob to the warm air gear in winter, because this situation would not consume fuel.
A/C is also open in winter
In fact, in winter, when the warm air is turned on, the "A/C" button of the air conditioning panel should also be turned on. A/ C in addition to opening the air conditioning refrigeration function, but also open the compressor, the air blown out at this time is dry hot air, can effectively remove the window fog.
It should be noted that when A/C just opens this meeting, the defogging effect is not instantaneous, and the moment it is just opened may even fog more, so it is best to do a good job of defogging the warm car before departure.
At the same time, because the warm air comes from the temperature of the engine loose water tank, and the engine water temperature does not come up when the car is just picked up in winter, it is best to heat the car for a period of time after the car, wait for the temperature of the water tank to rise, and also do a good job of defogging in the car.
It is worth mentioning that many models with higher configurations are equipped with automatic air conditioning, and in winter, defogging only needs to turn on the AUTO function of the air conditioning panel and set a relatively suitable temperature in the car.
Since the A/C function can be turned on, the air humidity can be effectively reduced, and the water vapor content in the air conditioning duct system can be avoided as much as possible, and the mold in the air conditioning filter and air duct caused by humidity can cause odor. Therefore, the A/C function recommends that it can be used for a long time whether it is cold or hot air.
How is the internal and external circulation used?
In addition to the problem of whether to open A/C in winter, many people will also be entangled in the problem of external circulation and internal circulation.
In fact, whether it is open cold air or hot air, in order to make the early air conditioning effect better, you can first use the mode of internal circulation, so that the car first quickly becomes cold or hot, but the long-term use of internal circulation will increase the concentration of carbon dioxide in the car, making people prone to drowsiness and affecting driving safety.
It should be noted that on the air conditioning panel of many models, there is only one button inside the circulation. In this case, the press is the inner loop, and when not pressed, it is the outer loop.
When driving in a road environment with good air quality, the outer circulation can be opened to allow fresher air inside the car. Another function of the internal circulation is to create an isolated environment from the outside of the car when there is more dust and odor on the road, and to keep the air inside the car from external influences.
