Many bonsai fans understand that industrial negative pressure fans mainly perform well in natural ventilation, smoke extraction systems, exhaust pipes and other levels. In fact, industrial negative pressure fans are used to reduce temperature, and it is also its key role to deal with the high temperature and heat of industrial plants. Speaking of which, many people are likely to be suspicious and think that a high-power fan is not a central air conditioner. How can we cool the natural environment? Since its entry into the market, industrial negative pressure fans have been more and more recognized by customers because of their advantages such as cheap purchase price, low application cost, long service life, and small natural environment destruction. Nowadays, almost all areas are in use.

Industrial negative pressure fan cooling principle:

1. Air convection, natural ventilation of negative pressure, natural ventilation and cooling: We know that most of the high temperatures in the natural environment are caused by sunlight irradiation of engineering buildings, heating of industrial equipment, and dense physical pyrogens. The heat generated by this is surrounded by relatively closed engineering buildings, which cannot be cooled down quickly, resulting in hot and hot gas temperatures in the site. After the installation and application of industrial negative pressure fans, when the industrial negative pressure fans are working, the strong displacement can quickly discharge the gases with poor circulation of high temperature and hot commodities in the room, produce the development trend of thermal convection interchange in the gas circulation system, and even build a natural ventilation in the natural environment. Everyone understands the indoor ventilation in the house, and the temperature is certainly not easy to be good under the condition of natural ventilation, and it will not feel hot.

2. Indoor ventilation to cool the high temperature gas. Industrial negative pressure fans can not only quickly discharge the high temperature, heat and dirty gases in the room, but also introduce the fresh and cool outdoor gases into the room for thermal convection and exchange. The gas fluidity itself can reduce the temperature of the gas. In addition, the outdoor cool gas enters the room to carry out the combined cooling, and the gas temperature will of course be reduced.

For example, there's a good chance you'll be able to get to know it better. For example, in our daily life, everyone has a cup full of boiling water in their hands. Everyone wants the boiling water in the cup to cool down in a short period of time. One way is to blow a hairdryer into a boiling water cup (this type of method is slower, equivalent to the principle of a fan). Another way is to pour out the boiling water in the cup and replace it with water that everyone wants to be warm. This is the cooling principle of the negative pressure cooling fan. In turn, it makes the body feel cool, as cool as the wind.
