Many friends want to know the cooling effect of installing a negative pressure fan. After the fan is installed and used, how much it can cool the factory is also a question that users often ask me. I understand this problem very well. Users spend money to install it. Of course they want to know whether the effect is good or not, whether it is useful.

With the widespread use of fans in factory workshops, animal husbandry and other places, more and more users see it in the market or friends' factory workshops, but they do not really understand its characteristics, or they do not fully understand How does the negative pressure fan solve the indoor high temperature and sultry, just want to know what the temperature of the workshop that the fan can cool the workshop?

In fact, it is a wrong proposition to ask how much the fan can cool the workshop. We know that it uses air convection, and the physical cooling principle of negative pressure ventilation also knows that if the cooling effect is considered by how much the fan cools, it cannot give an accurate degree. As an example, you may understand that the cooling principle of the fan is just like the room with poor forced ventilation and no air circulation is quickly ventilated from the door and window gap. The faster the ventilation rate, the naturally cooler the room. I believe that in a house without air-conditioning, if we only use the strong outdoor wind to naturally hang in the room to create a cool and ventilated indoor environment, no one can answer how much natural wind can cool the indoor temperature.

The concept of how much the temperature can be reduced by the environment is generally to use the hot air blown from the air conditioning and refrigeration equipment to neutralize and cool the environment, and in how much time the environment can reach the temperature

How the fan cools the ambient air in the workshop is a complicated question. We can not pursue the degree of digitization, mainly to solve the problem of cool and comfortable environment. Temperature does not measure the environment of the workshop. In fact, the standard of whether the environment is good is the cool and comfortable working environment of the employees. We can also imagine that in workshops with high temperature and good air circulation, employees will naturally feel uncomfortable in places where no fan is installed. After installing the negative pressure fan and using it, if the high-temperature hot air does not gather, fresh air will continue to enter the workshop, and the whole space has a good air circulation and even a sense of ventilation. If you don't sweat and people work in the workshop, will you feel comfortable and cool?
