Ventilation device ventilatorequipment1G/T4549.7—2004
A device that circulates the air in the car, and at the same time draws fresh air from outside the car into the car, and discharges the polluted air in the car to the outside of the car. The ventilation belt includes ventilator, fan, fan, dust filter, air volume control device, etc. 3.2
Ventilator
ventilator
An exhaust device that uses pressure difference principle to cut off the air under the action of self-signed wind. 3.3
Mechanical ventilation mechanicalPentilalionUnder the action of a fan (such as a ventilator), the air is quickly transported into the car through the air duct to achieve the purpose of ventilation. 3.4
Natural ventilation
Under the use of natural wind, the air inside the car is discharged outside the car, and the air outside the car enters the car to achieve the purpose of ventilation.
