What is the working principle of negative pressure fan?

The negative pressure fan has the characteristics of large volume, super large air duct, super large fan diameter, large exhaust air volume, ultra-low energy consumption, low speed, low noise and so on. But many people do not understand the negative pressure fan, then what is the working principle of the negative pressure fan?

A: because sunlight and ventilation cooling of buildings, machinery and equipment, heat leads to ventilated place. Outdoor temperature is higher than the negative pressure fan indoor heat quickly discharged, so that the room temperature and the outside temperature is not flat, the workshop temperature increases.

Two, air flow away body heat, air flow and accelerate the evaporation of sweat absorbing body heat, so as to let the human feel cool, and cool the natural wind.

Three, negative pressure fan only ventilation cooling effect, there is no refrigeration function, cool is the human body feeling. Negative pressure wind function drop how much temperature is ignorant

With the use of four, and the water curtain, when the hot summer temperature in the workshop can be controlled within 28 degrees Celsius. But the body cool feeling can be compared with air-conditioning, but a long time in front of the curtain of the people will feel cold could.

The above is the working principle of negative pressure fan, and we hope to be helpful.
