Air conditioner. A fan doesn't actually cool the air - it simply circulates it.

Why is it best to place a room heater on the floor but air conditioner near the ceiling?
Because according to physics heat goes upward from downward and cool air goes upward to downward so it is best to place heater on the floor but air conditioner near the ceiling
Explain the construction of an air conditioner?
it compresses a gas (freon or something like it), which heats the gas. Then it cools the gas (radiator grill on the outside) Then it lets the gas expand ... which cools the gas ... which cools the inside air.
Why are air conditioners placed high on walls and not on the ground?
Because the cool air from the air conditioner is denser than the warm air in the room and sinks. Placed high up the cool air will have time to get further from the air conditioner before it settles to the floor, allowing it to cool more of the room. Placed on the floor the cool air will mostly pool around the air conditioner and very little of the room will be cooled. Some air conditioner are actually placed relatively low in a room, but they have fans and baffles that blow the cold air upwards to the ceiling resulting in the same effect as placing the air conditioner high (maybe even better as the fan blows the cool air not only up to the ceiling but across it, possibly covering a larger volume of the room than cool air falling passively from an air conditioner placed high but without fans).
Why do you put air conditioners near the ceiling?
Not all AC's are in or near the ceiling. Many go in windows and there are a number of portable units. But the principle is, heat rises, cool air falls. So the higher the cool air starts to fall is, the more warm air it cools on the way down.
What is the working principle of an air conditioner?
If you are asking how it cools down the room, air conditioner or its vents are usually located at high areas. Since warm air rises, they take the warm air and make it cold. Cold air is denser and heavier which therefore falls. This process is repeated until the temperature of the whole room is the same. It uses a convection current.
What cools in hot weather?
An air conditioner
How cold can a 5000 BTU air unit get?
It depends on room size, including ceiling height. In a 9x12 foot room with 9-foot ceilings, my 5000 BTU air conditioner cools to about 60-degrees.
How is air cooled by air conditioner?
by the process of heat transfer.freon in air conditioner absorbs heat from air,as boiling point of freon is too low.thus air cools
Why are air conditioners placed near the ceiling of the room?
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.
Is using ceiling fans and the air conditioner at the same time?
Our air conditoiner is being installed as we speak. Can I shower and turn on the ceiling fan?
Why is an air conditioner more effective than a fan?
Because a fan only stirs up the hot air while an air conditioner removes humidity as well as cools the air.
What is the point of outdoor ceiling fans?
Outdoor ceiling fans circulate the air when it is stale or when there is no breeze. This makes the air cooler and therefore cools you down. They are usually found on patios.

Heat is to furnace as cool is to?
Air conditioner. One heats the interior of the house; the other cools it.
Is there something that I can buy that I can attach to my air conditioner that will point the air flow up towards the ceiling?
You will have to point your A/C blades towards the ceiling. Nothing else can be done in this regard.
My air conditioner stopped blowing in the back seat ceiling. Any idea what might be the problem?
no
