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.
Heat rises, so it is hotter near the ceiling than near the floor.
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.
if it is placed near the ceiling the hot it release will go upwards and people in floor will not feel the hotness and it is because hot air is lesser in weight and it Will fly in the top.
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.
Conduction
Heating vents should be placed near or on the floor in a room because heat travels up not down.

Cold air falls...warm air rises
Heat naturally moves to colder air. Place the heater on the floor and it will rise to the ceiling, as it is lighter than the cold air.
It would be better to place the heating vent near the floor because the heat will travel up and down, so that way the room would be heated evenly. If you place it near the ceiling, the heat would not heat the floor that well, since the heating vent sucks back in the heat
