This allow cool air to enter into the room.
minimum height of a habitable room is 2.18 meters and maximum is 4.2 meters.
a ceiling is the area that whatever room you're in, that if you look up you will see. a roof is the exterior top section of a building or house
For example, any object at room temperature or near room temperature.
Because of one simple science fact : “Cold air is heavier than warm air” When an air conditioner is at a certain height, it cools the air surrounding it, this cool air being heavier moves towards the floor of the room, meanwhile displacing the warm air already at the floor to the top. This warm air again gets cooled because of the air conditioner and the process repeats. This causes a uniform cooling of the room. Suppose if the air conditioner is at the bottom of the room, it cools the air surrounding it and this air stays at the bottom. The warm air towards the ceiling continues to stay warm for a very long time hence the cooling is not effective. It is for the same reason the freezer is at the top in a refrigerator.
In special areas with room to hold them, preferably near to a launch site, IE NASA.
the floor and the roof but not the floor
This allow cool air to enter into the room.
Heat rises, so it is hotter near the ceiling than near the floor.
Heating vents should be placed near or on the floor in a room because heat travels up not down.
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.
hitler killed them by sending them in a gas room with no ventilations
in one of the rooms the roof is broken near the corner of the room. there is a platform for you to reach it and go through the roof.
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.
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
book -room on the roof
Through the fricken window!
Cold air falls...warm air rises
