Ventilators are made for the removal of hot air from room and the windows are made for the supply of cool air. Since hot air rises up and cool air goes down,ventilators are made at a relatively higher height than the windows.
In respect to this, why ventilators are made near the ceiling?
The ventilators made close to the ceilings, because hot air is less dense compare cold air. Therefore, hot air moves up towards the ceiling and ventilators help to remove hot air from the room. It controls the temperature of room as the hot air is removed through ventilators and it decreases the temperature of room.
why are ventilators and exhaust fans kept at the top or ceiling level? Fans are fitted near the ceilings or on the sides of the walls due to the convection current as the warm and light air rises up and escapes through the fan.and fresh air comes inside the room through windows as the air is cooler and heavier with respect to the air that was ventilated out of the room.
Also asked, why are ventilators constructed above the windows?
So ventilators help to move out hot air from the room and lower its temperature. Hot air in the room rises and goes out the ventilator as cool air is drawn into the house from under the doors for example or other lower openings in the room.
Why ventilators are provided near the roof?
Ventilators are meant to pass the hot air of inside a room to pass outwards. As hot air is lighter than cold air relatively, it goes up near ceiling & pass through ventilators. Hence, this ensures a circulation of air inside a room.

Why are ventilators in houses provided at the top of walls?
Ventilators are provided in the rooms at the top of the roofs, just below the roofs because if the air inside the room gets hot thehot air rises up and flow through these ventilators and thus cool air remains at bottom so that to relive in hot sumers.
Why is ventilation provided in a room?
Ventilation is the process of supplying outdoor air to an enclosed space and removing stale air from the space. It can manage the indoor air quality by both diluting the indoor air with less contaminated outdoor air and removing the indoor contaminants with the exhaust air.
What are the two types of ventilation?
Ventilation. Natural ventilation is the use of wind and temperature differences to create airflows in and through buildings. There are two basic types of natural ventilation effects: buoyancy and wind. Buoyancy ventilation is more commonly referred to as temperature-induced or stack ventilation.
What is proper ventilation?
Ventilation. Ventilation refers to the exchange of indoor and outdoor air. Without proper ventilation, an otherwise insulated and airtight house will seal in harmful pollutants, such as carbon monoxide, and moisture that can damage a house. Proper ventilation helps keep a home energy-efficient, safe, and healthy.
How many types of ventilation are there?
Ventilation systems can be categorized as one of four types: exhaust, supply, balanced, and heat-recovery.
Why do we need ventilation?
Why is Ventilation Needed? Ventilation is needed to provide oxygen for metabolism and to dilute metabolic pollutants (carbon dioxide and odour). Ventilation is additionally used for cooling and (particularly in dwellings) to provide oxygen to combustion appliances.
What is a passive vent?
Passive ventilation is a natural ventilation system that makes use of natural forces, such as wind and thermal buoyancy, to circulate air to and from an indoor space. These ventilation systems work to regulate the internal air temperature as well as bring fresh air in and send stale air out.
How do you get natural ventilation?
B. Design Recommendations Maximize wind-induced ventilation by siting the ridge of a building perpendicular to the summer winds. Naturally ventilated buildings should be narrow. Each room should have two separate supply and exhaust openings. Window openings should be operable by the occupants. Provide ridge vents.
How do I keep my room well ventilated?
3 Ways to Keep a Room Well-Ventilated Turn on Those Fans. Just because you run the air conditioner doesn’t mean you shouldn’t turn on your ceiling fan. Open Interior Doors. Even if you don’t run your fans, opening all interior doors can allow air to circulate throughout the home. Use a Box Fan on Occasion.
How does a ventilation system work?
Exhaust ventilation systems work by depressurizing the building. By reducing the inside air pressure below the outdoor air pressure, they extract indoor air from a house while make- up air infiltrates through leaks in the building shell and through intentional, passive vents.
What is ventilation rate?
Ventilation rate. Similar term(s): inhalation rate, breathing rate. Definition: The amount of air inhaled in a specified time period (e.g., per minute, per hour, per day, etc.); also called breathing rate and inhalation rate.
Why rooms are provided with ventilators and exhaust fans?
Answer: Rooms are provided with ventilators and exhaust fans near the top sidewalls because the air we breathe out is hot and stale which means that is of low pressure. The winds blowing from the exhaust fans and the ventilators have fresh air which is higher in pressure.So,it blows downwards.
