Window Air Conditioner

[ceagle]

True Readings by Meter:

10 amps
1050 watts
7 volt drop
2 kw/h /h
That's about 30cents to 50cents per hour to be cool, depending upon which tier we will eventually fall into at the end of the month.

wow 8|


(I can't recall if it's a 10k or 8k BTU, ..the manual is for both and the unit has no identifying marks.)
(We had a 5.5k one before, and it was useless)

That's a pretty decent amount of money, but when you need to cool off, sometimes you just need to do it. It's easy to put on a sweater in the winter to conserve heat. Shedding excess heat isn't so easy.

eeeep.. yes, but heh, just a few weeks a year hopefully *wagwag*

I got the heavy duty extension cord intending to isolate the unit on it, but logistically so far it seems easier (due to the layout) to instead just put everything *else* on the cord, so the a/c will still be essentially isolated. The rest of the room needs a bit over 2 amps, but that's enough to push the breaker too far apparently. :P

I have a standard multimeter, but it's hard to measure alternating current on it with the cords I have. so I've got the Kill A Watt (http://www.amazon.com/P3-International-P4460-Electricity-Monitor/dp/B000RGF29Q/ref=sr_1_2?ie=UTF8&s=electronics&qid=1279455455&sr=8-2) to check things and it works great!

It's prolly pulling 12-13 amps for a few seconds whenever the compressor cycles on which is your breaker tripper.
Actual consumption should be close to 1.2 kWh per hour based on your numbers.

Yes, that sounds right, and probably significantly less when the compressor isn't running, so the actual usage would be based on the duty cycle of the compressor. My 5000 BTU unit is undersized and the compressor runs constantly, so that's 5A continuously. Buying an undersized unit and having it run continuously can be less efficient than buying a bigger unit that cycles on and off. My bedroom really needs at least an 8000 BTU unit to cool off completely.

Crittah!

Not only are ya bouncy, fluffy and fun... ya got a shmardt hayd on yer shoulders, too.... ;>
*wingfuzzles ya, gratefully*...
Dat's purty much on track, me friend!... The first readings I got I was rounding up a bit since I didn't have cumulative data (and wasn't shore wot to eggspect)... After running 6 hours the meter showed almost 7.5 kw/h, so you are right on track!! ^v^
Thanks for that extra breaker info too... :}
