Heating Ventilating and Air Conditioning

Can you use a window air conditioning unit in a room that does not have windows and just put it on a counter?

There are A/C units available that do not require window

installations, they are stand alone units. If you have a window

unit and use it on a counter, you will not only have a flood

(condensation)but you will notice that the back of the air

conditioner is very hot, thus heating the air that you are trying

to cool. It will work for a bit but you will eventually reach a

plateau where the air will not get cooler.

A portable A/C needs an exhaust pipe to expel the heat and

condensate out of the room.

If you put a window A/C unit on a counter, not only will you get

a pool of water, the room temperature will increase as the only

thing being added to the room is heat in the form of electricity.

An A/C unit works by moving heat from one place (the room) to

another place (outdoors). In doing this work, it uses electricity

that is given off as additional heat. If the entire unit is inside

the room, it will move heat from one side of the room to the other,

but because of the added energy, the average room temperature will

continue to increase to the point where the heat transfer out of

the room through walls is equal to the electricity coming into the

room. That will not happen until the room temperature is higher

than that of the adjoining rooms.
