What is the principle of negative pressure fan

The ventilation working principle of the negative pressure fan: the negative pressure fan is a kind of high air volume and low noise indoor building, which is manufactured by Seiko through professional special fan blade angle design, external dimension design, air volume and pressure design, motor matching design and other procedures. Ventilation and cooling equipment. When the negative pressure fan is energized, a strong exhaust air volume is quickly generated through the mechanical kinetic energy, and the indoor high temperature, sultry, stagnant air is quickly discharged to the outside, and a pressure difference is generated between the indoor and outdoor air, and the indoor air is quickly formed. In a negative pressure state, fresh air with strong outdoor pressure will naturally be introduced into the room for forced convection exchange. In layman's terms: in a relatively closed space or container, if the air is drawn out, a low pressure will be formed in the space, which is lower than the air pressure outside the space. Power can be used to draw air vigorously in the factory building, which will quickly generate negative pressure in the factory building, and use the doors and windows of the factory workshop as air inlets, which is enough to allow the air outside the house to enter the factory to form air convection, which is the ventilation of the negative pressure fan. working principle.

The working principle of cooling the negative pressure fan: One of the major reasons for the high temperature and sultry indoor air is that the indoor air is stagnant, and the air flows at a certain speed, which will naturally reduce the air temperature. We know that although electric fans cannot change the air temperature , but you can use the weak agitated air flow to make people feel cool. The passage between the two buildings, if there is wind, will definitely be cooler than in a workshop space where the air is sealed and does not flow. In fact, the negative pressure fan uses the physical principle of negative pressure ventilation and air convection to achieve the purpose of indoor cooling.
