Types of workshop ventilation methods:
Classified by use
风工程 系 统 。 1. Ventilation for industrial and civil buildings Ventilation engineering systems aimed at treating pollutants generated by industrial production processes and people and their activities in buildings .
风工程系 统 。 2. Smoke prevention and exhaust of buildings to control the flow of building fire gas and create smoke-free evacuation routes or ventilation engineering systems in safe areas.
系统 。 3. Accident ventilation Excludes a large number of combustion, explosion hazard or toxic gases, and evaporation ventilation engineering systems generated by emergencies .
Classified by the power of air movement
1. Natural ventilation relies on the wind pressure caused by outdoor wind or the heat pressure caused by the temperature difference between indoor and outdoor, so that fresh air from the outside enters the room, and the ventilation method for the indoor air to the outside is natural ventilation.
2. Mechanical ventilation relies on the power of the fan to send or discharge air into the room. This is a common ventilation system. The reliability of the system is high, but it requires a certain amount of energy.
By ventilation service area
1. Local ventilation Controls the spread of pollutants in local areas of the room or controls the ventilation of local areas where the concentration of pollutants meets hygienic standards. Local ventilation is divided into local exhaust and local air supply.
2. Comprehensive ventilation Comprehensive ventilation is a ventilation method that sends clean fresh air to the entire room, dilutes the harmful concentration in the entire workshop to the maximum allowable concentration, and exhausts the air containing pollutants to the outside. This type of ventilation is also called dilution ventilation.
