Yes...I'll do that for you..my time is somewhat limited, so it my seem a little slow,but yea..I'll put together some things and show some of the crazy shit we've made with these mods to cheap window units...you can use any size you want...and never need a window...I like the newer ones with the ozone friendly freon...and digital therm...you can dial them right in with that...and gas them back up without having to be licensed HVAC...another plus...if you look at the design of most all window units...you can almost cut them all in half...attach the length of copper line between the 2 halfs at what-ever distance needed...extend a few wires the same length...add a cheap fan to the rear half you removed...done...I leave the mounted factory fan on the frt half for the air going into the room or fixture...and just add 1 for the rear coil now that it's seperate...a cheap mini box fan...approx 10.00...will suffice...the rest is just tape and duct board..I'm putting one now in a boat of mine and will show you how it's done...again it's simple and requires a little creation...but it saves lots of cash and will do the same thing as any mini-spit...you'll like this once you see how it's done...BOK I think I get it now. I would like to see more pics if you would please.
Nice work!!!
Could you explain the cutting one in half and making it a mini split? With pics if you have them..
Thanks

Hell yes I'm in for the show. I'm a nob Trying to plan for the summer. thinking about trying to use ground water to cool. seems cheaper than buying a chiller. excavating is cheap for me but this sounds very interesting.
Heat exchanger? like a radiator with a fan blowing through it with a thermostat to control the fan. Tty can you recommend some good reference material to help me engineer this system? In your opinion would this be more economical than a chiller? I'v seen a lot of your posts and I respect your opinion.You can install a heat exchanger to put excess heat into your groundwater, and this will give you cheap cooling. You'll need to use water to cool things with, but that's an efficiency improvement as well.
Never fear; MacGuyver is here!

Tanks stone.
The air to water exchanger will be the one in your grow room. That water will stay in its own circuit, from grow room through a pump to something that cools it and on through a reservoir to the room again. The exchanger at the cooling end would be cooled by the groundwater, right? How do you get a constant flow of ground water across that exchanger? Solve that problem for free heating. Just sticking a radiator in the well and hoping for the best ain't gonna cut it, because there isn't enough active heat exchange going on. It will take awhile to get hot, but once it does it will stay that way because the heat can't escape very quickly.
If you can pump up a small amount of ground water to the surface and run it through a water to water exchanger before it goes to house, animal trough, garden barrel or whatnot... that would provide a very substantial heat sink at low cost.
I was thinking more along the line of closed loop geothermal just for cooling. But if I ran the loop through my furnace in the winter win win. I already have closed loop geothermal furnace just don't want to mess it up. The bride would kill me.
want to design the cooling for the grow rooms and eventually rdwc on it's own system. I think i'm starting to understand. ground loop through reservoir reservoir water through a manifold for different loops. water to air exchanger, rdwc ect. Now how to size and control. sorry for post jacking.
Geothermal cooling for grow rooms? Umm someone help please lol
