Information
The exhaust fan is a kind of air conditioner, which is driven by the motor to rotate the blades and drive the air flow to exchange air inside and outside the room. Also known as ventilation fan. The purpose of exhaust is to remove the dirty air in the room and adjust the temperature, humidity and feeling effect. Exhaust fans are widely used in homes and public places.
 
The exhaust fan can be divided into partition type, conduit exhaust type, conduit intake type and full conduit type according to the air inlet and exhaust port. According to the air flow form, it can be divided into centrifugal type, axial flow type and cross flow type.
 
There are three ways of air exchange for exhaust fan: exhaust type, suction type and combined type. The exhaust type enters the air from the natural air inlet and exhausts the dirty air through the exhaust fan; the suction type inhales the fresh air through the ventilator and exhausts the dirty air from the natural exhaust port; and the use type is that both the suction and the exhaust are completed by the ventilator.
 
The exhaust fan belongs to a kind of axial flow fan. It is mainly used in negative pressure ventilation and cooling engineering and is called exhaust fan. The exhaust fan has the characteristics of super large air duct, super large blade diameter, super large exhaust air volume, ultra-low energy consumption, low speed, low noise, etc.
 
Use together with cooling water curtain can solve the problem of ventilation and cooling at one stroke. During the operation of exhaust fan, a negative pressure environment will be formed in the room. If a cooling water curtain is installed on the other side of the air outlet of the exhaust fan, the exhaust fan will not only discharge the indoor hot air out of the outdoor, but also enter the indoor low-temperature air with rich water vapor through the cooling water curtain into the indoor intake, so as to achieve the effect of ventilation and cooling.
