Hope this doesn't sound like a stupid question, but I'm thinking about buying a one room AC unit that hangs out a window. At the warehouse store, they have several units plugged in and just sitting there, not haning out a window. The units seems to work OK, they are pumping out alot of cold air, and they are on all day long. Why is it they are suppose to hang out a window? What would happen in my house if I just set it on a table?
Thanks, Please post here.

Because the heat removed from the inside air has to be exhausted outdoors. Otherwise you're simply pumping the heat right back into the room.
Not quite; you would be running a poorly designed dehumidifier.
they leave them sitting there for display to sell it to someone.... the a/c unit has to sit outside of a window to let the hot air exit from the back... if you just put it in your house you gonna have the compressor running trying to make cold air pumping it into the front of the unit, and the back will be pushing out into the same room the heat that was taken out the air in the front of the unit.... a NON WINNING situation..... it would be a waste of time running it....it would be like having a refrigerator with no doors on it.... the food will never get cold.
Window AC dump the heat out the back of the AC. If you have it in the room, it dumps all the heat into the other side of the room. So, with the AC on the table, the net effect is to make the one side of the room cooler, and the other side warmer.
Really.?. A top posting mormon is going to teach us about Jesus??? Incredulous.
A slightly technical explanation might clarify things. The air conditioner compresses the cooling chemical in the system, causing it to heat up. Passing the hot chemicals through a radiator outside makes it shed heat. The compressed chemicals are thus cooled outside the house (they are hotter then than the outdoor temperature). After cooling, the chemicals are allowed to expand again. Since the pressure is reduced, so is the temperature, so inside air can be blown over the chemical cooled coils to cool the house. The process is repeated over and over to move heat from inside the house to the outdoors.
FUCK CHINA
The first thing you have to realize is that "cold" is merely the absence of heat. An air conditioner just moves heat from the front evaporator (cooling) coil to the rear condenser coil where the outdoor air can take it away. If there is nothing to take the heat away, it just stays in the same basic area.
While an air conditioner would still blow cooled air out the front, it would blow hot air out the back and into the same room. There would also be the added heat generated by the fan motor and compressor which are doing work. The end result would be a room hotter than it was before.
Keeping both sides of an air conditioner inside a room would be like trying to cool a swimming pool by taking the hot water out of the deep end and dumping it into the shallow. There would be no effective change in overall pool temperature.

If you did this you would actually heat the room. an A/C doesn't actually cool a room it just moves the heat outside. in doing so the compressor creates it's own heat added with the heat it moves. leaving the whole unit inside would just heat the room it is in.
