What is exhaust ventilation fans' working principle

Exhaust ventilation fans are cooling principle, the use of air convection, negative pressure ventilation by the fan and motor.

Exhaust ventilation fans installation location of the object: the doors or windows, natural inhalation of fresh air, the indoor heat gas quickly exhausted to the outside to force any ventilation can improve the machine, cooling ventilation, the effect of up to 90% -97%.

Ventilation cooling: sunlight, buildings, machinery, equipment, human and other heat sources lead to the need to be ventilated places higher than outdoor temperatures.

The role of exhaust ventilation fans are as follows:

First, The indoor heat of a fan can quickly discharged, the room temperature and outside temperature the same, and will not shop within the temperature.
Second, the air flow away body heat, air flow to speed up sweat evaporation and absorb body heat, thereby allowing the body to feel cool, and natural wind cool.
Third, Exhaust ventilation fans only ventilation cooling effect, cooling function, cool the body's feeling. Exhaust ventilation fans or down temperature is bogus.
Forth, curtain used in conjunction with the hottest in the summer workshop temperature controlled at 28 degrees Celsius. Exhaust ventilation fans is suitable for all cooling places.
