So the room I'm trying to cool is about 200 square feet. The A/C I pasted the other day is only rated for 165.
I have that same model A/C in another room and it cools it well enough but that room is about 170 square feet. I notice that in addition to making that room nice and chilly, the rest of the apartment gets a tad bit cooler too.
If I ran both at the same time 24/7, would they be able to meaningfully impact more than the space they're rated for?

I'm using a little room unit that cools my whole house. Mind you, it doesn't make the house chilly, but it takes the humidity out of the air and takes the edge off the heat. Even on Sunday it didn't have to run full time. We run it in the midrange for temperature and on the low economy setting for the fan. In spite of muppet's hysterics it's not too horribly inefficient to keep the house comfortable.
How much wood in each room? Bedroom, library? Plus, do you close the door for the first hour or so?

Room I'm trying to cool is living room.
Room with the A/C already is bedroom.
No wood at all really, except for the floors.

I've noticed wood helps cool the room faster. Our master bedroom which doubles up as the library cools much faster than our second bedroom. The MB has a 1 tonne window ac
(19000 BTU) and is about 175 sq. ft. and takes about an hour to come down to a freezing 18 deg. cent. from an ambient temperature of 31 deg. cent. Night temp. here is generally 28 deg. cent. for about 11.5 months a year. The other 15 days it drops to 25 deg. cent. Our second bedroom is slightly smaller with the same tonnage but takes longer to cool. Ventilation ducts are sealed in both rooms when AC is on.

Room area vs A/C size is only some kind of big fuzzy hand-wavy approximation. It all depends on how hot it is outside, how many windows there are, how well insulated the house is, how cold you want the room, how many people and heat sources are inside, all sorts of things.
Your best measure is to take the rating of the unit you already have and compare it to your needs as you have already done. That will be a much better predictor than "square footage" on the description. To compare ratings between units use tons of refrigeration or Btu/hr rather than square feet.

I'm just going to buy the damn thing and see what happens.
July 11th, 2007 2:40pm
Worst case scenario I can just buy a third one for the other end of the house and run all three!

can one cool a room by putting ice in a bucket and letting a fan blow across the top of it?
which side of the fan should my PC be on?
July 11th, 2007 2:41pm
I would put the PC on the sucking side. It may not make much difference, but I'd worry about condensation on the blow side.
July 11th, 2007 2:47pm
yeah that's good. i'm just gonna stick my feet into the bucket.
