What Is Mechanical Ventilation?

The use of the operation of the ventilator gives the air a certain amount of energy, causing ventilation pressure to overcome the mine ventilation resistance, so that the surface air continuously enters the downhole, flows along a predetermined route, and then exhausts the dirty air out of the well. The ventilation method is called mechanical ventilation.

Full ventilation is to ventilate the entire room, and use fresh air sent into the room to dilute the concentration of harmful substances in the entire room to below the allowable concentration of sanitary standards. At the same time, the contaminated polluted air in the room is discharged directly or after purification Go into the outdoor atmosphere. Comprehensive ventilation includes comprehensive supply air and comprehensive exhaust air, both of which can be used simultaneously or separately.

Local ventilation refers to the use of local airflow, which means that the local area is not polluted and forms a good air environment. Local ventilation includes local supply air and local exhaust.

The mechanical ventilation system is generally composed of

Selection of mechanical ventilation conditions: Most of the domestic ventilation conditions are still selected by manual operation, but there is a trend of computer control. With the development of science and the gradual maturity of computer control technology, automatic control will gradually replace manual operation, and the inaccurate factors caused by manual operation will gradually disappear with the development of computer control.
