How to count energy used by Air Conditioner?

Question

I mean, if I use 1 HP (horse power) air conditioner, say for 8 hours per day, howmany KWh will be read at the end of a month? Can it be calculate?

Answer 1

certainly

Kilowatt-hour = 1.3410 horse power-hours

so, 1 HP* (kw-hr/1.34 hp-hrs)* 8 hrs = 5.7 kw-hrs

so, if you were really using 1 horse power for 8 hours, that is the same as 5.7 kw-hrs

multiply that times the number of days in the month and voila

of course, the fact that you have a 1 horse-power motor doesn't mean that it draws exactly one horsepower, and the fact that your air conditioner is on and blowing, doesn't mean the compressor is under load

Answer 2

Not really, the power is only an indication of the maximum consumption rate. Examples will make it easier to understand.

Lets take two example of situations you could have this AC running:

1) A cool region (around 25C), with the thermostat set at 22 C, running in a small bed room with good insulation;

2) A hot region (around 35C), with the thermostat set at 18 C, running in a large living room with the window opened.

In the first case, the AC unit would spend a lot of time with only the fan working and with the compressor off while in the second case the compressor might be running all the time the AC is turned on. Because it is the compressor that really consumes energy (and is what the 1 HP refers to), the same unit would have completely different consumption.

Answer 3

Nope. You seem to think of that the physique of ideas of air con has extra of an result on the ecosystem than the different equivalent capacity use. It does not. seem at it this way. you have a field. It has an air conditioner hooked as much because it. in case you run the AC for 10 minutes, enable's say it takes a million BTU of warmth out of the field. And, enable's say that drops the temperature interior the field with the help of 5 tiers. If the warmth is moved to a close-by of *comparable quantity*, it will develop the temperature with the help of 5 tiers. yet while that is moved to a close-by that is 5 cases the quantity, it will develop the temperature in basic terms a million degree. And, except that's a *very* great field, the Earth's environment is orders of value (thousands, thousands, thousands and thousands, or billions of cases) extra desirable than the field, so the temperature will flow up decrease than the AC is dropping it with the help of. you recognize this intuitively. you may desire to heat a chafing dish fairly properly with a candle, although if it would have in basic terms approximately no result on your finished homestead. further, the warmth does not stay out of the field, except that is completely insulated. ultimately, in case you go away the AC off, the field will flow lower back up 5 tiers in temperature (assuming it became into at ambient temperature previously, and ambient temperature hasn't replaced). this suggests that the a million BTU of warmth which you took out of the field is now lower back interior the field. So, different than the capacity and warmth from the AC unit itself, no longer something has replaced. Or, short version, ACs are shifting warmth around, however the warmth does not stay moved, and the bigger something is, the extra warmth it desires to fairly replace in temperature. heaters, different than warmth pumps, have extra of an result on worldwide temperature, because they actually promptly create warmth.
