What is the unit size of the window A / C would be more effective in a room of 280 sq ft?

What is the formula for the size Btu vs. Board? I do not want either oversized or because I do not have many power options and I'm shaking all what I can from (1) 15Amp room circuit.This will also (2) c. fans, mini-refrigerator, (2) small flat-screen televisions, a chain stereo and lights. Because of this and my reluctance to put in another circuit, it should be (close to) exactly the right size unit that possible so that it will work, but not pull too much amperage.

Assuming you do not really want to see the engineering formula for calculating BTU vs. room size, cooling rate, the total temperature drop, etc., see this http://www.lowes.com/lowes/lkn?action=howTo&p=BuyGuide/AirConditioner.html table includes a table in the middle of the article suggests that your room would be better suited with a capital A 7000 BTU / C. They generally operate about 850 watts. Assuming you are on a 15A circuit, this leaves you with about 500 watts to spread your other fans / / frig TV, etc. If you a hi-fi big, you may need to change your choice of music from "hiphop hot" to "cool rock" to avoid blowing your breaker. LOL. If you add your energy and find it makes you give up too many of your toys, be sure to use a smaller AC or chiller evaporative like this http://www.amazon.com/Sunpentown-Portable-Evaporative-Cooler-purifier/dp/B0007W03IK/ref = pd_bbs_9/102-2621557-3174512? ie = UTF8 & s = home-garden & Qid = 1189064097 & sr = 8-9. This evaporative cooler is only 60 watts, leaving enough power for your other devices. Another advantage is that it is a lot CHEAPER to run an A / C, because there is no compressor (in this comparison, it is about 8x cheaper). Major drawbacks are that it will not cool the room as cold as a CA, you must meet periodically with the cooler water (after several days), and it does not work well in high humidity.
