acparker's solution is genius.
May I suggest a water-to-water-to air heat exchanger? If I was building that's what I would do: Drill a ~8-10" hole 20ft deep.
Sink a ~8-10" capped PVC pipe maybe 18ft long with a box on top for maintenance
Insert a copper pipe double helix secondary water pipe into the PVC
Put the water-to-air equipment wherever convenient. Drilling a hole is easier than cut and fill trenching. The PVC is a passive tank. The copper pipe contains the working fluid. I saw this proposed in Pop Mechanix, minus the obvious improvment of the double helix. |
I know there's the risk of radon gas, which is why I'm trying to get the air to go around the outside so that it won't go into the home directly!! And I don't want the crawl space being open to the house itself to prevent the risk of creating a "chimney" effect if the house catches fire!! A lot of people don't know just how much having a airspace on the outside of your house to allow air through can reduce your necessary cooling!! On new construction my dad, brother and I try to do soffit vent all the way around the house with ridge vent, and the attic won't get more then maybe 5 degrees Fahrenheit over the outside temp drastically reducing cooling costs!!! What your talking about with the pipe is something else I'm looking into for interior cooling, but right now I'm mostly working on the "envelop" cooling possibilities for now!! I really think
That having the "envelope" around the outside will naturally cool the interior!!
