Why is artificial wind not as cool as natural wind?

Artificial wind actually gives people a "cool" feeling, but it is usually not "cool". Many of us have had this experience. It was clear that the temperature in the air-conditioned room was low, but we felt sick all over.

When the night is cooler, we open the windows and feel relaxed and happy with the wind. Why is that?

What is wind? Wind is more than just the movement of air. The real wind includes a series of indicators such as temperature, humidity, oxygen content, odor, etc., and the difference between these indicators is the biggest difference between artificial wind and natural wind.

Air conditioners and electric fans are essentially internal circulation, that is, the air in the room is blown out after being treated, soThe humidity, smell, and oxygen content of the air are the same as the original air in the room, and even air conditioning can reduce the humidity in the air.

In short, artificial wind actually only gives people a "cool" feeling, but it is often not "cool". On the contrary, as long as the conditions are right, for example, in a stuffy and crowded room, the window suddenly opens, and the wind blowing in from outside is not only cooler and more oxygenated, but also very pure compared to the smell of sweat in the room, even with the fragrance of natural flowers and plants. This wind is, of course, "cool" and "cool".

But on the other hand, if there is garbage outside the window, and it happens to be noon in the hot summer, then if you open the window of the air-conditioned room at this time and a gust of wind blows in, I'm afraid you won't feel "cool". Therefore,As long as the conditions are right, we should open more windows for air exchange, not always stay in air-conditioned rooms, or have more contact with nature, which is good for our physical and mental health.

Because of the natural wind, he feels very comfortable, so it feels very cool.

Because artificial wind is made by people, it is said that there is no natural wind, so the effect is good.

The natural wind is actually very cool, but the artificial wind is hotter.

The artificial wind also only accelerates the flow of air to produce this feeling.

That's not necessarily, the sun is directly exposed in the city during the day, and the wind blows like a heat wave, if the temperature of your room is higher than the outside ambient temperature, then the wind circulating by the electric fan is not as cool as the natural wind outside.

The wind blows out of the open area or in the mountains!

The natural wind is the flowing air, which is fresher, while the fan is the opposite, the air in the house is not circulated, and if the fan is placed outside, the blowing effect will definitely be much better than in the house!!

Because your place must be hotter before you turn on the electric fan, then in the hotter place you use the fan to blow out the wind is naturally hotter, if you take the electric fan to the mountains without the sun to blow it is also very cool!

The strength of the fan is constant, and it will not be strong or weak, so that when you first turn on the fan, you will feel cooler. After a period of time, the person's sweat is blown dry, and there is basically no sweat evaporation, and it will not be very comfortable. The natural wind is generally gusty, weak and strong.

When a strong gust of wind blows, the body's heat is taken away by the wind, and it will feel very cool.

When the fan blows, it will take away the heat of the human body, but this heat will circulate in the room for a long time, which will increase the indoor temperature;

Natural winds, on the other hand, are usually supplemented by cooler air currents elsewhere.

The natural wind generally blows from the open air, bringing fresh air containing more negative oxygen ions, so it feels particularly cool when the natural wind blows, while the fan wind has been circulating indoors, and the comfort is not as good as the natural wind.

The main reason is the oxygen content of the air, because our ** can also breathe oxygen, the oxygen content of natural wind is higher than that of indoor wind, the oxygen concentration in the body is higher, and the natural wind contains more air negative ions, the main function of negative ions: negative ions have sedative, analgesic, antitussive, anti-itching, diuretic, increase appetite, and lower blood pressure, so blowing natural wind must be much more comfortable. The wind of the electric fan is only forced to supply air by the surrounding air, the temperature remains the same, the intensity has always been the same, and it is naturally uncomfortable to blow for a long time.

The fan wind is just the machine to blow up the warm wind around you to bring coolness, the natural wind is determined by the weather, and the wind coming over is the wind naturally formed in nature, so it will be cooler. If you are satisfied, please adopt, thank you.

My old-fashioned Great Wall brand floor electric fan has a gust function, and they all have a certain period, and the falling burst represents no turn.

Natural Wind Natural Wind As the name suggests, because it is natural, it is comfortable, hehe

Everybody is the same, they all like the feeling of natural wind

There's a lot of oxygen in the natural wind. And the wind speed is relatively small. The blow is more comprehensive.

There is no temperature difference in the natural wind, and our ** is easy to accept. The air conditioner will blow out at a lower temperature than the room temperature, and we have just started to have an adaptation process. This is the initial shallow truth. Therefore, we generally think that the natural wind is more comfortable.

First of all, the natural wind is healthier than the air conditioning wind, I don't know if the landlord has heard of the air conditioning disease, the air conditioning is biting cold, so it is easy to get rheumatism, the natural wind is very OK, the green is the best.

Air conditioning has air conditioning sickness! This can show that the air conditioner is artificial cooling air! Of course, it's not as refreshing as the natural air!

Of course, although the air conditioning is good, it is not as good as nature.

The natural wind blows from a distant place, and there is a hurry, which is very suitable for the reception of the human body, and the electric air and air conditioning are forced to circulate over a short distance, and it is difficult for people to feel comfortable, but sometimes it still works.

When using an electric fan.

The ambient temperature is the same.

The fan only forces the air of the same temperature to move quickly, and the "wind" formed has no ability to lower the surrounding temperature.

It is only possible to force the temperature of an object with a higher temperature than the surrounding environment to the surrounding environment, and the person is still in an environment where the temperature is not lowered.

So people don't feel comfortable.

When using the air conditioner.

Air conditioning is generally used for cooling in summer.

The air conditioning outlet is generally about 10 degrees, much lower than the ambient temperature, if people blow the air conditioning directly, there will be cold on the blowing side, and the hot feeling on the side that is not blown is caused by the imbalance of vasoconstriction in the whole body, and there will inevitably be discomfort and even discomfort.

The wind speed of the Category 0 wind is meters, the wind speed of the Category 1 wind is meters, and the wind speed of the Category 2 wind is meters. According to this knowledge, the human mouth can blow a wind of magnitude 0-1.
