Holy Moly. An engineer making an arithmetic mistake.
Just curious what is Rhone Power Consumption? I googled it and came up with some stuff about environmental studies in France.

 

At full load yes, but under typical operating conditions no. Running at full load for an hour, a 0,75 HP air conditioner multiplied by 750 watt/HP = 560 watts, divided by 1,000 watts/kW = 0,56 kWH

Most of the power consumed by an air conditioner goes to running the compressor. When the air conditioner is running you will sounds from two components in the air conditioner. The fan will make a typical fan noise and the compressor will make a rattling noise.

Although the fan runs all the time, the compressor of a non-inverter type cycles on and off during the operation depending on how hot the room is. This is because the typical air conditioner cannot vary the RPM speed of the compressor motor. It can only turn it on and off. An inverter type air conditioner is able to adjust the RPM speed of the compressor so this type slows down the compressor which is a little bit more efficient.

The air conditioner will consume less power during the times that the compressor is off or running at a slower RPM.

So to answer your question it depends on how hot the room is. 0,56 kWH is for full load only.

 

Yes, I googled it and found the same information so you have your answer

Okay. Very good.
So why did you throw out the term Rhone Power Consumption in your attach on Jimever?
I was impressed with your EE^2 degree up until now.
, Rhone stuff is fine if you're talking global warming, I don't really consider air-conditioning in that realm.

 

If you want to do this yourself (DIY), then the next step is to isolate the A/C unit and check its current draw. You should be able to do this by turning everything in the home off except for the A/C. Modern electrical meters are digital and have an instantaneous readout. There is usually two readouts. The larger display is the cumulative watts since the meter is installed. The other smaller readout will cycle through a series of numbers. Instantaneous watts or kilowatts, Amps, volts, etc.

First turn everything off and check that the meter reads 0. Then turn on the A/C and let it run for a few minutes before reading the instantaneous watts and amps. Compare these readings with what is shown on the nameplate.

If you have an analog meter things are a bit more challenging. Find a friend or hire a technician with a portable ammeter.

 

I think some people are confusing Kilowatts with kilowatt hours. A 220v aircon drawing say 10 amps (thats big) consumes about 2,200 watts of power. Run it for an hour and you have drawn 2.2 kilowatt hrs of power from the grid which you pay for. (Unit cost plus all the other crap added to your bill here). The question I have is, how many hours did you measure that aircon to obtain a figure of 27 kilowatt hours? If it was only 1 hour you have a very dangerous aircon. Something wrong with your 27,000 watt hours mate.

 

I haven't read (or understood) all of the technical power analysis reports, but I did see that he mentioned that it seems to be colder now. I had a similar problem with my split aircon, and it turns out that the remote control is also the way in which the main aircon unit senses the temperature (at least with my unit). Putting fresh batteries in my remote made it go back to working normally. So (at least with mine) you need to be careful of where you place the remote as that is where the temperature will be monitored (so don't put it on a table where the sun shines on it for example), and make sure to keep good batteries in it.

 

27ooo watts over 24 hours equates to an aircon at 220 volts drawing around 5 amps. Sounds about right to me. (220 x 5 x 24 = 26,400) that should be a cold aircon I think.

 

Thanks for the feedback. This kind of explanation clarify why a split unit is more consuming friendly than a window unit. It makes sense that with an room temperature of 34 degrees Celsius you wanna reduce to 28 or 24 degrees for example, it will make a difference how much Kwh is needed during the hours the unit is running. No more questions............!
