Expansion:

Exhaust fans, driven by electric motors A type of air conditioning appliance that rotates the blades to exchange indoor and outdoor air. The purpose of exhaust is to remove indoor dirty air and adjust the temperature, humidity and sensory effects. Exhaust fans are widely used in homes. and public places.

Ventilation principle:

When the exhaust fan discharges air to the outside, it will cause the indoor air pressure to drop and the indoor air to become thinner, forming a negative pressure area. , air flows into the room due to air pressure difference compensation. In practical applications in industrial plants, exhaust fans are usually installed centrally on one side of the plant, with the air inlet on the other side of the plant, and air convection is formed from the air inlet to the exhaust fan. Blowing. During this process, the doors and windows near the exhaust fan are kept closed, and the air is forced into the workshop through the door and window on the side of the air inlet. The air flows into the workshop from the air inlet in an orderly manner, and flows through the workshop. The workshop is exhausted by an exhaust fan. The air exchange is thorough and efficient, and the air exchange rate can be as high as 99%. Through specific engineering design and designing the ventilation speed and wind speed as needed, any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problems can be completely solved at one time. The ventilation effect can be achieved within a few seconds of turning on the fan.
