Since the winter has become colder, it is inevitable to turn on the air conditioner and blow warm air when driving in winter. However, there are many doorways in the use of vehicle air conditioning, and many drivers and friends are half-aware, and if the use of the wrong one will directly affect the fuel consumption of the vehicle. Today, let's talk about what things to pay attention to when driving in the car, and whether to turn off the A/C key when driving in winter? Can turning off the A/C key really save fuel?
In winter, the A/C key of the wind-blowing air conditioner is very effective
I believe that every owner has been troubled by the foggy window, such as the vehicle window is very easy to fog when the humidity is high in rainy days and the temperature difference between the inside and outside of the car is large. At this time, the use of car air conditioning warm air to remove fog is to open the A/ C key, because the car air conditioner can not only adjust the temperature in the car but also with dehumidification function. Opening the A/C button can absorb the hot moisture in the car through the evaporator, which helps to remove fogging frost and condensation from the window at the same time. This is why the setting of the vehicle, the A/C key to open the defogging function of the air conditioner is automatically turned on, the purpose is to remove the moisture in the car faster, which helps the window to remove fog.
Warm air mode open A/C key to blow out or warm air
Some car owners will inevitably have such a question: "Isn't the A/C button of the vehicle air conditioner used to open the cold air?" Is it okay to open the A/C key when driving in winter to blow warm air? "On this issue, in practice, we can conclude that when the car air conditioner blows warm air, even if the A/C button is opened, it is still a warm air. A / C key is actually the vehicle compressor working switch, whether the air conditioner is cold air mode or hot air mode needs the compressor to work to adjust the temperature, so the air conditioner blows warm air open A / C key blows out or warm air.
The air conditioner only blows warm air and does not need to turn on the A/C key
In normal car use cases, if you drive in winter just to blow a warm wind and do not need to remove fog, you do not need to open the A/C key. The vehicle air conditioner can be heated by a plumbing system, which uses the coolant heat of the engine to heat the air, and then blows the hot air into the car through the blower to become a warm air. In this way, the warm air is provided without the need to open the A/C key, that is, there is no need for the compressor to work for heating.
Therefore, in the normal use of the car environment in winter, just if you want to blow warm air, you do not have to open the A/C button, so that you can save more fuel. According to relevant experimental research reports, the fuel consumption difference between the A/C key and the A/C key is not opened when blowing the warm air is about 15%. Of course, the effect of opening the A/C key to blow warm air will be better, and it can also dehumidify to prevent fogging of the windows.
In fact, the A/C key function of car air conditioning is almost used for refrigeration. Although heating is also possible, the vehicle itself can be heated by the heat of the engine without the use of a compressor. It is recommended that riders can occasionally open the A/C button when using the car in winter, so that the vehicle compressor can run for a period of time, so that the various components of the vehicle will be better.
Speaking of car air conditioning Xiaobian also reminds all car friends, after the second-hand car is bought back, we must maintain or replace the air conditioning filter of the vehicle, and the air conditioning filter will accumulate a large amount of dust after a long time of use, making the air conditioning air conditioning air out of the air, and may also breed bacteria and so on. In the process of purchasing a second-hand car, we must remember to check the historical record of the second-hand car, the maintenance record of the vehicle 4S shop and the insurance record of the car insurance, and through the record query, we can help us identify the accident car problem car.
