We have a small bedroom in our house, and it doesn't have heating/air conditioning.
In the bigC(and many other places) they sell these portable air conditioners. The pink one here in the photo can heat the room up, and cool it down:
The ones I've seen so far don't have any specific temperature settings.. It's just a "hot" and a "cool" setting..
Does anyone have any experience with these things. Do they work?
They are not actually airconditioners as such. Are these the kind that you fill with water or ice? If so they will do very little to cool things down and are no replacement for an airconditioner in the humid summer. I have a few of these which I use to assist the main airconditioners in classrooms on hot days.
I tried one of these before in my guest bedroom at home and it was totally rubbish. It didn't cool the room down at all and the hassle of carrying dripping bags of ice around the house was not worth the effort. A good, strong fan was much more effective and in the end I had a small a/c fitted. I don't know about heating, I only wanted to cool down, and this appliance did not do the job.
actually this is really funny.
In order to make a room cool,
Air conditioner cool down the room, and leave hot out of the room.
not only hot in room, but also air condition's heat.
every electronic makes heat such as PDP TV, Air conditioners, small air conditioner, and others.
Small air conditioner might cool down the room for while, but soon your room will be hotter because hot stays and small air conditioner will be heated and make room's hotter
You might try this: Put a floor fan in the doorway of your bedroom facing away from the room. It will pull hot air out of the bedroom and throw it into the other room. This has worked for me in the US with a bedroom turned into a computer room with several computers and monitors running full time. Hot as Hades, only one vent from the central unit plus a ceiling fan.
You could also try installing a ceiling fan where your overhead light is in the bedroom. Just moving the air around will cool you off, but I wouldn't count on it to be cool enough in the summer here. Plus everything will start to mold w/out some a/c.
