Ventilation
26th January 2009 by Boating Laws No CommentsVentilation
Ventilation is the process of removing musty air in a space such as in a room and letting clean air to move inside. It can be used into different context such as architecture, mining, physiology, and firefighting. In mining, underground mine aeration allows the flow of air in the location to dilute gasses under the ground. The fans used in here consume a large volume of energy. When it comes to firefighting, to be able to locate and put out the fire, the firefighters remove the smoke first through creating a draft with an opening.
There are three different kinds of ventilation namely mechanical, infiltration, and natural. Having a local exhaust fan installed is an example of mechanical ventilation. In here, there is a unit that enhances the flow of air thus increasing its rate. For natural aeration, there is no device mounted but only open windows that lets the air flow naturally into the space. When it comes to ventilating underground spaces like basements, vents aren’t recommended since there will be changes in the humidity factor causing some problems. Meanwhile, infiltration is different from ventilation but it is used to supply air. Infiltration means that the passage of air into the space is unintended and can be described as air leakage. On the contrary, the leakage of the air from the building going outside is called exfiltration.
Equipments that are used for ventilation are fume hood, air handlers, breathing and ventilating air systems, dampers, diffusers, louvers, energy and heat recovery ventilations, refrigeration compressors, steam injection heaters, and vents and venting systems.
