New Air Conditioner Process Cuts Energy Use 50-90%
necro81 writes "The US National Renewable Energy Laboratory has announced that it has developed a new method for air conditioning that reduces energy use by 50-90%. The DEVap system (Desiccant-Enhanced eVaporative air conditioner) cools air using evaporative cooling, which is not new, but combines the process with a liquid dessicant for pulling the water vapor out of the cooled air stream. The liquid dessicant, a very strong aqueous solution of lithium chloride or sodium chloride, is separated from the air stream by a permeable hydrophobic membrane. Heat is later used to evaporate water vapor back out — heat that can come from a variety of sources such as solar or natural gas. The dessicants are, compared to typical refrigerants like HCFCs, relatively benign on the environment."
It's cheaper than using trained hydrophobes. Or are they used to create the membrane?
Nae king! Nae laird! Nae yurrupiean pressedent! We willna be fooled again!
And how are they going to pipe down solar gas into your server room anyway?
which is totally what she said
I know my wife is going to be asking for an AC in the house this summer
Really? Another one? I've been visiting her for months.
I lost interest at this point. Wake me up when biochemists and medical doctors get a chance to run test case groups about the adverse effects of lithium in their localized atmosphere, typically inhaled into the lungs and later causing one's sense of reality to become skewed.
In order to get lithium chloride vapor in the atmosphere, one would have to raise the temperature to about 1600 Kelvin at normal atmospheric pressure. Under those conditions, I propose blind panic as a suitable coping strategy.
I don't think the researchers anticipated tha eventuality that somone would open up one of thier units and drink the liquid inside.
So if they don't do stuff like that, then whats the point of having grad students?

Oh, those fucking nanny-state latte-drinking faggie euro-trash tree-hugging abortionist lesbian pot-smoking liberals! That be a strike against liberty!
God gave me the right of freezing to death without having that nanny-state surplus heat fed into my heating system. If I want heat, I'll buy my own oil and heat myself, thank you!
First, you accept their surplus heat, then you go to the hospital for free, when you least expect it you're all dressed in red, singing "The International".
A desert is an ocean with its life undergound, and a perfect disguise above.
Or is it the other way round?
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Indeed. I would highly recommend that you seal your house 100% hermetically.

heatsinks are NOT noisy
They never make a sound when _you_ are in the room, but just wait until your back is turned. They're bitchy little things.
