We see doors and windows in our room in daily life. They are placed in such a way that we can pass through them easily. But, when we see ventilation, they are always placed at the top of the room. Have you ever imagined why are they placed on the top, why not near the window? We will discuss why ventilations are placed on top of the roof in this article.
Ventilations are basically window like structure that is used to pull out hot air in a room. Ventilation moves outdoor air into a building or a room and distributes the air within the building or room. The general purpose of ventilation in buildings is to provide healthy air for breathing by both diluting the pollutants originating in the building and removing the pollutants from it.
Ventilators are kept at the top of the roof to pass the hot air inside a room to pass outwards. As hot air is lighter than cold air relatively, it goes up near the ceiling & passes through ventilators as a result cold air finds its way to come in to fill the room. Hence, this ensures a circulation of air inside a room. Also, ventilation at the top ensures an ample amount of sunlight to enter into the room.
During night time, ventilators allow the cold air to flow inside the room. It also secures the oxygen level in a crowded room by circulating air.
Home ventilation is important to keep the house and its occupants healthy and comfortable. Ventilation is a key component to maintaining proper indoor air quality. Ventilation keeps air flowing through the home, eliminating contaminants, moisture buildup, and odors.
