Inner or outer circulation? It's a big fart thing. So, let's make it clear from the perspective of farts. Oh, no need to smell farts, the wrong method will only be smoked. I didn't talk much because I hadn't heard of a few people being smoked to death. There is no doubt that the external air circulation will not be carried out at high speeds, but there are many old drivers who do not know the knowledge and skills of how to use the air conditioner. Let's try to expand this problem. For example, how does the in-car fog eliminator work? Do I need to turn on the A/C button for warm air in winter? After reading it, I understand.
First, open the inner cycle or the outer loop to see if the "fart" is inside the car or outside the car. The concept of inner and outer loops is easy to understand, but the icons of the buttons are clearly drawn. The internal circulation refers to the "closed window" isolated from the outside world and relatively closed. The outside air can't get in, and the air inside the car can't get out. The outer loop is the opposite, which is "opening the window". When outside air comes in, the air inside the car can also be discharged. I want to know when to start the outer loop and when to start the inner loop, it's simple. Where is the "fart"? Farting in the car, do you have to open the windows for ventilation? That's right, the outer loop! Unless you're going to filter this fart with your own respiratory system. If the fart is on the outside, use the inner loop. Nobody wants to open the window and smell farts, right? Easy to understand, right? But that's not the end of it. You still have to know. What is a "fart"! It's a metaphor, in fact, referring to dirty and polluted air. That is to say, it depends on the inside of the car, outside the car, where the air is fresh.
1, in general, the natural air is fresher and fresher, we drive, most of the time should use the external circulation. After all, the people in the car are breathing, the concentration of carbon dioxide will increase, and it will be difficult to breathe for a long time, which may cause dizziness, fatigue, mental atrophy, and increase the probability of accidents. 2. What if it is a foggy day? Or, through chemical plants and crematoriums, the air is filled with a foul smell. It was obviously farts on the outside, and nothing was getting inside the car. Toggle the inner loop, close the windows and skylights. 3, parking, traffic jam switching in a short period of time cycle switching, but also because there is a "fart" outside. That's the exhaust of someone else's car. There are many vehicles, waiting for idle speed, exhaust gas concentration. Many models are equipped with the same function, parking automatically switching inside the loop. When encountered, do not compare with the system. 4, if you fart inside and outside, the smog outside is very serious, take off your shoes in the co-pilot position in the car.... Take the power of the two evils lightly, at this time, or why the outer circle? Many high-speed cars have an on-board PM2.5 filtration system, and even if they don't, foreign air will enter the air conditioning filter, which has some filtration effect. If it is not poison gas outside, it is better to go out and cycle.
5. Stop and turn on the air conditioner to sleep. Inner or outer circulation? Do you know why you are fat? Getting this wrong can really kill people. 10 years ago, Beidaihe could not book a room almost every year, so some people drove to sleep! The internal circulation must not work, the concentration of carbon dioxide increases, and the external circulation is not necessarily no problem. In a closed place like a garage, if the air circulation is not smooth, even if it is external circulation, you are inhaling the exhaust gas of your own car. Parking was circulating outside in the ventilated area. Second, open the internal cycle or the outer circulation, to see whether you want to be cold or hot according to the air quality is very simple, but another factor is the temperature. There is air conditioning in the car. It's cold outside, the inside of the car is warm air, and the air is hot. On the contrary, in the summer the car is cool inside and hot outside. If it circulates outward, the comfortable temperature inside the car will be lost with the air circulation, energy consumption will increase, and the experience will also be affected. Therefore, the temperature factor should also be considered for internal and external circulation. Simply put, if you want to maintain the temperature difference between the inside and outside of the car, you want to carry out internal circulation, and if you want to be closer to the temperature outside the car, you can carry out external circulation.
1. When the temperature is suitable in spring and autumn, the window can be fully opened. High-speed window opening increases wind resistance, and external circulation ventilation is also a good choice. If there is no problem with the outdoor air, there is no need to switch. 2, open hot air in winter, open air conditioning in summer, and always open external circulation will increase energy consumption, mainly internal circulation, and occasionally open external circulation ventilation. It doesn't take much time. The space inside the car is small, and the air will circulate in 2 or 3 minutes. If it's automatic air conditioning, you don't have to care. Do not switch manual mode. Switch between the inner and outer loops yourself. 3, just get on the car in the summer, the outside of the car more than 30 degrees is also cooler than the car, do not rush to open the air conditioning, but open the window ventilation, so that the tanning hot air in the car dissipates, and then open the air conditioner after being consistent with the outside world. Not only for fuel saving, formaldehyde will volatilize after tanning in the car, and the formaldehyde content in the air is correspondingly higher.
Three. The reason why the windows are lined up is because many people are wrong. Automatic air conditioners usually have a defogging button on the front window, and when fog appears, press it, and the fog will disappear in three or five seconds. But. Isn't it cold? Summer is nice, but it's raining outside, and even if it's cold, it's not very bad. If it rains in autumn, it is obviously not warm, but the cold wind is coming... Even sadder is that you don't dare close the door yet. Fog immediately after closing the front window also affects driving safety. Do you think that's all there is to it if it rains? Actually, you are mistaken. There are at least three ways to stop smog. Press the defog button on the window, or use the manual air conditioner to turn on the cold air, the maximum air volume blowing on the front window is the "cold air defogging". The effect is fast and will appear immediately, but the disadvantage is... cold. Open the window, the storm is more intense, the temperature inside and outside the car is the same, and there is no fog on the window. Everyone should know the principle of fogging. Although it is fog, it is actually a small droplet of condensed water. The hot water vapor in the car hit the cold glass and condensed. Therefore, when the external circulation is opened, ventilation, and windows are opened, the temperature inside and outside the car is the same, and the fog disappears. However, such a disadvantage is that it is cold and slow.
The third method is the "hot air mist eliminator", because the principle of fogging is to know - hot water vapor meets a cold window, and to remove the haze, either cool the air in front of the window or heat the window. The latter is the principle of using hot air to remove fog. The operation is also very simple. If you feel cold, sending out a warm wind is over. Without using a mist eliminator, the window is directly blown out by a warm wind, and the AC power is turned on. In a short period of time, the fog of the window will become larger (because the air is heated first, and the fog will become thicker if the hotter air touches the cold window) After a while, the temperature of the window glass will also rise, the fog will disappear naturally, and you will become comfortable. The downside is slow. In addition, there are thick fog stages in between. If the road conditions permit, you can park and wait a while. Four. About the A/C key This button is the switch button of the air conditioning compressor, and the air conditioner will be turned on automatically in the summer. After manual shutdown, there is no longer a cool breeze and it becomes ventilated. Needless to say the air conditioning in summer, the question is does the heating need to be turned on in winter? Many old drivers, the warm air is the engine, turning around, turning around rolling around rolling around, rolling around, the correct way to use it is to drive, such as fuel vehicles, hybrid vehicles, pure trams and so on.
Air conditioning not only has a cooling function, but also a dehumidification function, and opening the AC can effectively avoid blurred windows. Why press the window defogging button and A/C lights up automatically? I just said warm air mist eliminator, why should you turn on A/C? It is to use the dehumidifier function of the compressor. A lot of people are wrong because it does go against common sense. Warm air is emitted, but A/C is cold air. Isn't this the water supply pipe and drain pipe of the pool open at the same time? Otherwise, just like your faucet, if you want to emit hot air, the air conditioner will not get into the car. In addition, refrigeration is related to temperature differences. It was already cold outside. Even with cold air on, the electricity is small. At present, most of the models are variable displacement compressors, to put it bluntly, it is a frequency conversion air conditioner, and the AC is only the power of the dehumidifier, which is almost negligible. Even the old-fashioned fixed-capacity compressor is on and off, and the energy consumption is not very high.
Finally, you'd better turn on the air conditioner and switch to ventilation a few minutes before parking. I've seen bloggers say the wrong thing, so I'm going to make a special correction here. This is of course an effective way to avoid air conditioning odors, as many car manuals emphasize. The blogger said it would take a few minutes to dry, but it wasn't. Ventilation is not about drying water droplets in air conditioning lines. Water droplets are formed by condensing water vapor in the air after the air conditioner is turned off and the water vapor in the air hits the cold pipe. Ventilation only reduces the humidity in the pipeline while raising the temperature, and the temperature inside the line is consistent with the outside temperature, and even if there is a small amount of water vapor, it will not condense. In fact, the ventilation time will not be too long. After entering the community, stop the communication and change to ventilation. Enough work to park the car.
