air command air conditioner

As I see it you will either be in a CP, and have paid the $ amount for the night. Turn it on and enjoy. "All paid for".

Or; you are running on a generator, and the cost will be the fuel.

The type/make or aircon is irrelevant to the above.

So, if you are full time travelling it will be one of the above. Or, a day when aircon is not needed.

Regards.

Hello hetho, it is true what you say. I would still like to know the answer though. Kind regards. Rocket

These air conditioners have shocking performance if you wanted to run it off a battery. A 2500 watt home air conditioner has an input of about 420 watts.

Anyway the manual states 5.6 amps cooling, it doesn't say a lot, people obviously don't demand efficiency when buy caravans.

So about 1344 watts input for 2800 watts output.

Easiest option is get a plugin watt meter & turn off everything else & run the AC for awhile. It may get a bit more efficient once it has cooled down a bit.

The original poster asked how much it costs to run. This depends on the temperature difference between what you want inside and what is going on outside. Worst conditions - A/C running 24 hrs per day - 1344 watts (1.45 kW) x 24 = 32.3 kWh per day. Now, depending on how you get that energy, it could cost you say 30 cents per kWh, in which case it will cost $9.68 per day. This is for maximum demand ie the compressor running flat out all the time. Obviously it won't run like that all the time and depending on the temperature difference between what inside and outside, the compressor will cycle on and off. During the day it will probably be going all day. You have to estimate how long the compressor will run (when it is cooling) - say 6 hrs per day, then the cost will be 6/24 x 9.68 = $2.42 per day. When the compressor is not running, the fan still goes, but that draws very little power.

The energy costs you can also calculate yourself by using the applicable rate where you are using it. Simply divide $9.68 by 0.30 and then multiply the result by the energy charge you will be paying eg if you are paying 40 cents per kWh, the charge would be 9.68/0.30 x 0.40 = $3.22 per day.

If you are using a petrol generator to power your A/C. you can expect to get about 5.6 kWh out of a litre of petrol. This means that at say 6 hours per day you would use about 5.8 L of petrol. All this has been calculated using basic theoretical values. I would be interested to hear what others have found in practice when running an A/C with a petrol generator. As you can see from the above assumptions, there are a lot of variables to consider.

Thankyou so much erad. You have answered my question. Have wondered for a long time how much i used. You were very helpful. Kind regards. Rocket

I have a Carrier, an Advent, and an Atwood A/C unit on my bus. It is a toss up if the Carrier or the Atwood is the better unit in terms of cooling. The Atwood is the only unit that is a heat pump. The heat pump performs very well in the 40s and 50s. The built-in thermostat is horrible in heat mode and won't maintain constant temps. The temperature display will show a degree or two below the set point yet the unit is not producing heat. The heat mode just doesn't do anything below about 35 degrees. The unit just makes all kinds of noise with basically no heat output. Air Conditioner reviews
