How much electricity consumption is done by an Air Conditioner ? (In an Hour)?


Question: How much electricity consumption is done by an Air Conditioner ? (In an Hour). I wantto buy an Air Conditioner capicity of 1.5 tons. I would like to know how muc electricity it will consume per hour?
Answers: Air Conditioners are rated in BTUs, usually 5000 BTU for a small one, 10 or 15 or 20 thousand BTUs for bigger.

One kilowatt/1 hour = 3412 BTUs

So, if you divide the BTU rating by 3412 you will get the kilowatts consumed by your A.C. per hour.

Example: 20,000 BTUs A.C.

20,000 divided by 3412 = 5.86 kilowatts/1 hour

This A.C. will use 5.86 kwhr electricity every one hour.

Electricity is about 10 cents per kwhr. This A.C. uses 59 cents worth every hour. About $10 per day, assuming usage equals 17 hours at full power.

This comes to about $2.50 per day per 5000 BTUs assuming the heavy use, equal to 17 hours at full power.

There should be enough here for you to answer your question. If you still cannot answer it, you need to grab some sharp, nerdy kid and show him this and ask for help.
