What does it cost to run a portable air conditioner? - industrial air conditioner
I bought a 9000 BTU air conditioner B & Q:

but I am curious how much electricity they use, confused. The brochure says:
"The annual energy consumption, kWh in cooling mode: 577"
"The cooling power of 2.8 kW"
"Energy Efficiency Index 2.41"
When I called 1kW 10 pence per hour (TBH I'm not sure what) the cost of electricity, is the 577kW average £ 57 per annum? Or do I have the math all wrong as usual?
The device has a power consumption of 1200W, but I doubt it works on that level .. 1000W = 1kilowatt so if I run it 10 hours a day would be € 30 per month! That sounds awfully expensive for me.
Please can someone tell me what it really costs to run, because if there really 30 pounds per month, which could bring him back is to the B & Q and buy a fan / Commercial Industrial instead.

= 2.41 watts cooling per watt of input power. So if you are 2.8 kW of cooling watt input at this level 1200 watts. But it contains uses that are not purely cooling - as the fan and possibly an evaporator and / or a condensate pump if available.
So start with the input power. Units feature air conditioning system for vehicles, the drive power required to operate the fan at the highest level and the compressor at the same time - in other words, max.
Take operate the unit, twelve (12) hours per day, in which the compressor runs for six (6). Assume that the fan is on average, not quite complete.
His average speed will produce a combination of 6 hours to 90% of full charge.
6 hours, until () to 20% of the full record of the fans.
6 x 0.9 x 1200 = 6480
6 x 0.2 x 1200 = 1440
1440 + 6480 = 7920
7920/1000 = 7.9kwh/Day
= 79 pence per day
79 x 30 = 23.70 pounds per month.
100 daysn / a = 7900 pence, or 79 pounds per year.
These figures are very similar - more or less depending on the time used and the actual load on them. However, expenses such as motor units with air conditioning, power consumption is very close to the actual consumption when operating at maximum. And the compressor has a single operational level, the difference is only in the fan and other incidental expenses, and no more than 30% of the total load, even if the.

All Yall are wrong. Kilowatt-hours of energy is not consumpton is real. The energy in kilowatt-hour is the product of the engine power in kilowatts and the time in hours, not "kilowatts per hour."
With a 60 watt light bulb consumes one hours 0.06 kilowatt-hours of electricity. With a 60-watt bulb for one thousand hours 60 kilowatt hours of electricity consumed. I think multiplying with 577 kWh Dang What a kilowatt of world.It will say that the cost of work for puppies under 25 pounds per year in the United Kingdom have.
conditiones really need an air compressor with high energy intensity
desirable that the litle room and there are a lot of people are entering or leaving the problem in the RAL
For example, in a car not a problem that all windows are closed and no one opens doors Opne
