Building displacement ventilation is a type of ventilation that utilizes the natural convection process to provide fresh air in a building. This system works by supplying fresh air at a low velocity near the floor level of a room or space. As the fresh air flows along the floor, it gradually displaces the stagnant air in the room, creating a natural upward flow towards the ceiling. The stale air is then exhausted from the upper part of the room or space.
Building displacement ventilation is often used in building design to improve indoor air quality, reduce energy consumption, and improve occupant comfort. By supplying fresh air at low velocities, this type of ventilation system requires less energy to operate than traditional forced-air systems. It also helps to reduce the concentration of pollutants and contaminants in the air, potentially reducing the risk of health problems such as respiratory infections or allergies. Additionally, building displacement ventilation provides a comfortable environment for occupants, as the fresh air is distributed evenly throughout the room and does not create drafts or hot spots.
