Industrial ventilation fans cooling principle
8/12/2012 7:38:07 PMVentilation fans belong to a sort of axial fan.Mainly used in negative
pressure ventilation and cooling project called industrial exhaust
fan.The ventilator has a large wind tunnel, large diameter of blades,
large exhaust volume, ultra-low power, low speed, low noise
characteristics.
Ventilation fans outside the discharge process of the air can cause indoor air pressure decreased, the indoor air is thin, and form a zone of negative pressure, air pressure differential compensation inflow indoor. In the practical application of the industrial plant, ventilation fans are usually centrally set up on the plant side of the inlet in the plant room on the other side air intake mouth to the exhaust fan to the formation of convection hair. In this process, close to the exhaust fan near the windows and doors remain closed, forced air flows from the inlet side of the doors and windows compensation workshop. Air lined up order from the inlet into the workshop from the workshop flow through the exhaust fan discharge workshop. Ventilation, thorough, efficient, and ventilation rate can be as high as 99%. Specific engineering design, according to the needs of the design ventilation rate and wind speed, any fever, harmful gases, dust and smoke can be rapidly excreted workshop, any poorly ventilated can completely solve the one-off. Can be achieved within a couple of seconds to open the fan ventilation.
The hot indoor air of the ventilation fans can quickly discharged, and inhalation of indoor and outdoor other side of the air to reach the temperature and outside temperature flat, and will not shop within the temperature.Will take away the body heat in the operation of air flow, air flow to speed up sweat evaporation and absorb body heat, thereby allowing the body to feel cool, to obtain the same cool and natural wind.
