When it comes to the problem of car heating in winter, I believe that many people are very confident. Some people will even say, this is not simple? As long as the driver who will not use the warm air conditioning. But do car owners really use warm air? The following 5 mistakes to talk about, quickly see how many you have made.
First, think that the wind is stronger, the hotter the car will be
Many people think that the bigger the warm air in the car, the hotter the car will be. In fact, if the wind speed is relatively slow, increasing the wind speed can indeed make the heat exchange of the system larger. However, after the wind speed reaches a certain level, the heat exchange will not increase, and the temperature of the air outlet will decrease. This is due to an increase in wind speed, but insufficient heat transfer time. If the owner feels that the car has warmed up, he should reduce the wind speed and keep it in about second gear. If you keep turning on gear 4, it will not feel very warm, but it may cause the temperature to drop.
Second, the air outlet does not come out of the wind and thinks that the car is broken
Some car owners will find that even if they have a warm air in the car, some air outlets are not windy. No matter how to adjust it is useless, the temperature is adjusted to the highest, the gear is adjusted to the maximum, and there is still no wind. The owner will worry about whether the car is broken, in fact, this has nothing to do with the car itself. Because the temperature of hot air is relatively high and the density is relatively small, the air will naturally rise. Many cars are designed to get air out from the bottom, so that the warm air can run to the roof by itself through the convection, thereby forming a thermal cycle in the car, which is the fastest way to heat up in the car. Now there are some high-class cars, and they are designed to install air from under the seats. The air outlet near the center console is directly turned off and no air is generated.
This design has won the approval of many car owners, because even if the warm wind blows on the owner or other people, the wind will become cold and make people feel uncomfortable. Air from under the seat will make people feel more comfortable, many cars as long as the warm air, its central air outlet will not be airy by default, if you want to let it out of the air need to be manually adjusted.
Third, the internal circulation feels more comfortable
Many car owners think that the internal circulation of the open warm air is very warm and comfortable, in fact, this is a wrong idea, so the combination is indeed warm, but it is not necessarily very comfortable. Because the people in the car are breathing all the time, if the concentration of carbon dioxide in the car is too high, it will make people feel dizzy, nauseous, and anxious. If the inner circulation has been started in the car, everyone sitting in the car will gradually feel hot and uncomfortable. Even if there is only one person in the car, you can't keep driving the inner loop. It is necessary to open the external circulation ventilation frequently. If there are multiple people in the car, the frequency of ventilation should be more frequent. In this way, everyone will feel more comfortable, and they will not cause some unnecessary traffic accidents because of dizziness and nausea.
Fourth, turn on the warm air to close A/C
Many car owners believe that if the warm air is turned on in the car, the A/C must be turned off. Older cars used to require it, but not all cars now need to do so. Because now the car technology is gradually improved, the air conditioning in the car is also more intelligent, even if the button is turned on, the compressor will also work. So you can no longer look at things in the old way.
Editor's Comments:
Many car owners used to think that if they want to open the warm air in the car, just open it. In fact, there are still many doorways for heating to open, and I hope that car owners can integrate and use more.
