Ok, Maybe I'm hanging out here on this branch all by my monkey self but I'm seriously looking at creating an absorption chiller system either using ammonia or the lithium bromide. My goal, use waste heat or this damn heat wave we are having (and will continue to have if global weirding causes me to roast my chestnuts off) to drive an electric-less cooling solution for my house and for possible food storage but more likely air conditioning. So that being said, has anyone tried to DIY or know of a packaged product that could condition a 1200sq. ft ranch style home? TIA.
