Greetings everyone! After a long time lurking, this is my first Instructable, so be nice as I try to figure this out! :)
Okay, the Idea here is that I live in a older house that Was retrofitted to central air conditioning. The air handling unit of that AC was installed in the attic of the house. The condensation drip pan drains from the attic of the house, to the ground where it just.. kinda bleeds out to the ground.
Why not collect that condensation Run off and use it?
Now before any one starts screaming "OMGWTFBBQFREON!".. it doesn't work that way. the freon is on a closed system in the AC, its the stuff that transports hot energy away to make cold stuff... the Water we are collecting here is the condensation form the humidity in the air that is created from that exchange of cold and hot.... It's.. well.. a lot like the sweat on your glass of cold, clear, water as you chill out after a day in the heat, sun and humidity.
During the Dog days of summer, when I've measured it out? that condensation is averaging 25 gallons in a day.
So, yo get down to the nitty gritty of it? this is a basic rain barrel, I'm just harvesting drip water from my AC.
this instructable, as is, only qualifies to houses that have air handling units mounted in upper levels of houses. most newer construction usually has the air handling unit mounted in the lowest level of the house where the condensation runs right into a floor drain. there are float level devices out there that can be used to pump collected condensation water to a desired location. These things are purposely built for commercial ice machines, and add nothing but cost and complexity to this thing we are building.
I built this thing for about $15
The barrel itself came to me free from work. I work for a Microbrewery and the Barrel is what our sanitizing acid comes in. yeah, yeah chill out.. it's food grade. A blend of nitric and phosphoric acid. if you have ever drank a coke or a sprite? You drank this stuff. the MSDS lists it as 1,0,0. Granted, Ive seen the stuff complelty disolve a cadmium socket wrench socket in a week.... but that's besides the point. ;)
in any case, the plastic is food grade and the barrel is complely rinsed out and all is well in the world.
The standing frame is made from five eight foot sticks of outdoor treated 2"x4". Two sticks are cut in half to make four legs. the rest of the lumber is chopped down to 10 26" sections.
take two legs and frame a 26" stick to the top of the legs. next. measure 13 inches from the base of the feet. Frame in another short stick using the measurement as your base line.
Repeat for the other set of "legs"
use the next four short sticks to lock in the frame. the last two short sticks are laid across the top of the lower frame to provide the support for the barrel.
