With the way my discovery is going I'll have to sell the kitty too :toilet:
I can't live without a/c though if I had my way I'd live in a walk in freezer.:spudnikdaddyo:

I think solar assisted air conditioning is a more appropriate title. There is some more info on how it works here.
It still needs at least 150W to drive a pump. The thermal energy from the sun is use for compressing the refrigerant. As already mentioned, it would have to have the ability to run of the grid at night.
My fear with many energy saving ideas is that they become too complicated to be reliable. We'll see how many Prius' are still on the road in 20 years ...

That wouldn't matter because industry is the biggest user of electricity and peak usage is during the day.Quote:

awabbit posted the link hoadie ;)
It's a hybrid system using an ejector or jet pump and says it's similar in performance to an absorbtion system, which I'm guessing means it's a fair bit slower to pull down than your standard vapour compression system (compressor style heat pump)
A major advantage from my POV is simplicity and $ cost to run.
The old Electrolux caravan fridge style absorbtion system doesn't use any moving parts and only needs a heat source, but they are bulky and become inneficient at higher ambients. (a fan on the heat exchanger would help a lot IMO)
They also suffer from the problem of seperation of the ammonia, water and bromine if left to sit idle for some time, needing it to be mixed again for the system to work.
Fan motors will need to be employed with this system for efficiency, both to move rejected heat away from the condenser and move air over the evaporator and into the space to be cooled, so the power requirements will increase ;)
Sorry, didnt realse you had a D2........maybe we should have an appeal or something to help the D2 owners to afford to have Aircon fitted lol :DQuote:

Just need to plug it is, no sparky required as long as you get a 10amp one.
Split systems are great and quiet but are pricey to fit.
Yes an appeal would be good LOL:D I've got the box type in the lounge I get complaints from others in the house it is too cold it has no "settings". I think it is older then I am maybe from the late 70's. Surprising though it uses less energy than the modern spilt system equivelent. But yes it is very loud!
