ventilators are provided in the rooms just below the roofs because when the air inside the room gets hot this warm air rises up... and flow through these ventilators and thus cool air remains at bottom......so this is how ventilators make us relieve in hot summers ,i hope i made u satisfy by my answer :)

The floor and ceiling are each 13 and 1/3rd square yards.In order to calculate the area of the walls, we'd have to know the height of the ceiling.
The floor and ceiling each have areas of 72 square feet.In order to now the area of the walls, we would also need to knowthe height of the ceiling.
It depends on how high the room is and also the materials used for the walls, floor and ceiling.
The floor and ceiling each have areas of 100 square feet. In order to find the areas of the walls, we need to know the height of the ceiling.
Ventilators are typically placed near the ceiling because hot air rises, so they can effectively circulate and distribute air throughout the room. Placing them near the ground would not be as efficient in terms of air circulation and distribution.
Ventilators for rooms are typically placed closer to the ceiling because hot air rises and tends to collect near the top of a room. Placing the ventilator higher helps to draw out this warmer air and circulate it out of the room more effectively. Additionally, having the ventilator closer to the ceiling can help to prevent drafts or discomfort caused by direct airflow at head level.
1. To avoid too strong air currents near the body. 2. To avoid accidents by hitting the fan blades.
Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.
Heating vents are typically placed near the floor to ensure better air circulation and distribution of warm air throughout the room. Placing them near the ceiling may lead to stratification of air, where the warm air stays near the ceiling and doesn't effectively heat the room.
A room heater is typically placed near the floor because heat rises, allowing it to warm the air in the room more effectively and evenly. Placing the heater near the ceiling would result in the heat accumulating near the top of the room, making it less efficient in heating the entire space.
Hot air rises because it is less dense than cold air, leading to a concentration of warmer air near the ceiling. This phenomenon is known as convection. Heat energy also tends to accumulate near the ceiling due to factors like poor insulation and the heat distribution from various sources within the room.
The hot air is lighter than the cool air so it floats to the ceiling.:)
Depending on which type of ceiling panel, there are several benefits. Radiant ceiling tiles are an economic heating alternative. Suspended ceiling tiles enhance a room's appearance and provide sound insulation. Acoustic ceiling panels provide further sound control.

Cold air falls...warm air rises
Because of convection, the warmest part of a room is typically near the ceiling. Warmer air rises due to its lower density, while cooler air sinks towards the floor. This creates a temperature gradient in the room with the warmest air accumulating near the ceiling.
