Try leaving buckets of water in the hot room - the greater the surface area of water the better.
Heat = energy.
Evaporation of water is a transformation of liquid to gas phase, which consumes energy.
With water being evaporated, energy is thus consumed, and therefore the heat will decrease.
This is why coastal areas are cooler than areas inland.
Another trick regarding cooling a hot car is spraying a mist of water inside the car - the fine water droplets will evaporate into gas form, thus quickly dropping the temperature.
Try taking the temperature before and after adding buckets of water.

the japanese way of doing things is to put a wet cloth in front of a fan. thereby "air conditioning" the air that the fan is pushing.
GTO taught me that 
FYI, i live on the 25th floor (top) and it's always effing hot upstairs, but for some reason at our elevation, there's always a nice wind.

My portable AC units are fantastic.
Spend the $ on the 12000BTU.

hmm summers are probably only gonna get hotter so an A/c probably is a good investment, The portable AC i'm using isn't bad, it takes about 20 mins to actually be cold though but its just plug and go, It's only 8000 btu though, but good enough for a bedroom or an office.

I'm thinking about getting A/C for my house too.

hmm a lot of good suggestions besides an A/C unit I guess, some of the comments reminded me of those spray bottles with fans attached on them so it'd be like the cheap mans A/C
fack it's days like today that make me not want to get an A/C unit. If only every hot day was followed by a relatively cool day.
I was taking a look at futureshop website and saw a 12,000 BTU A/C unit for $450. Might just wait to see what type of heat July/August will bring before buying one.

I have a 12000 btu portable unit and a 5000 btu window unit. The 12000 btu portable is used to cool the main area which is about 600sf and it works fine. The 5000 btu window unit is used for my bedroom which is about 400sf and it works better then the 12000 btu portable unit. By the time I go to bed, it feels like winter in there. I much rather have a 12000 btu window unit on the main floor, but for security reasons can't.
12000 btu portable unit was going for as low as $400 at Rona about 2 weeks ago and 5000 btu window unit was between $90-$100 at most retailers. Now that it's getting hot, price went up to $450 and $150

13,000 BTU unit works well for my area. I close the bedroom doors and it adequately cools ~ 800 sq.ft to around 23degrees. Lots of heat comes up from downstairs and when the AC is off the temp quickly rises. I have also installed Low-E windows which cut down the amount of thermal heat that comes in significantly.
I also have an portable 8,000 BTU unit in the bedroom that I run for a couple of hours before I go to sleep to cool the room.
There are various calculators online that will help you decide what size of a unit you need.

What you want to do is have flow. Don't have all the fans doing the same thing.
I currently have 2 fans setup. One in the kitchen, and one in my room. It's usually cooler in my room, so that fan is set to intake, and the kitchen window fan is set to exhaust. This allows the cooler air to flow through my apartment, and the air won't get stale and hot.
I also make sure I close the blinds before I sleep, so the morning sun doesn't heat up my east facing living room. My neighbor would have sweat pouring from his forehead in the morning, when I see him in the elevator. He keeps forgetting to close his blinds.
My parents have one of those A/C units that sits outside the house, but they never use it. They don't have to. They just open up the vents in the basement, and have window fans in all the rooms upstairs, which are all set to exhaust. It pulls all the cold air from basement. Their place is always cool. | How big do your fans need to be? Just regular size? At night, outside air is cool, but inside air is stuffy.

For my Lennox one @ 5000Sq ft. house, it was only $7k + install. That being said, I had to make a snow shield for it so the snow didn't get trapped inside of it, but... it wasn't TOO too expensive...
Then again, it only brings down the heat comfortably in that size of a house, it's not ice cold tho.

Since it can't take up the entire space, I block off the rest with bristol board.

I do load calculations for buildings all the time. It depends almost entirely on the orientation and how large your windows are.
If you are north facing, a rule of thumb would be 20-30 btu/sq.ft. So 12,000 btu should be good for a 400 sq.ft space.
The "worst" orientation is south facing. You're going to want 40-60 btu/sq.ft. i.e. 24,000 btu will be good for a 400 sq.ft. space.
If you live in a new apartment with huge floor to ceiling windows, you will want to go even a bit higher.

Just so you guys know, I am having the exact same problem. I also have a AC unit but I took it out during the winter season. Now the heats back and I can't stand it! So I am going to replace my single pane windows with low e 2 pane windows. I will let you guys know if it makes a big difference or not. Should be happening this coming weekend. Something everyone could look into if this low e stuff works ;p cheap too.

I bought my a/c at the Brick near Ikea. The one I have works awesome, I got a good deal considering I shopped around and found this the cheapest. I just ordered another one for my room, this one is abit smaller 10000 BTU but it was on sale for 299.00.
Like I said earlier, in my opinion if you have the extra $ you might as well get the 12000 BTU. You can take it to a bigger space or you can take it and put the a/c into a smaller room...You have to love portable A/C's
