This necessitates the removal or dilution of air pollutants, smoke, and odour, as well as the regulation of humidity and temperature within the space. Where engines and equipment are present, ventilation is also essential to ensure a supply of oxygen for combustion, cooling, humidity management, and smoke or vapor removal.
The process of removing stale indoor air from a building, roof ventilated room, or restricted space and replacing it with natural fresh air is known as ventilation. As the oxygen level in an inhabited area decreases, proper ventilation is necessary for breathing.
