This is still in the conceptual stages so feel free to give input and bounce around ideas.
Anyways I've been trying to figure out a more economic way to cool my grow area. Between Arathu, Ferather, Myc, and me we've been bouncing around a few ideas and sort of merging them into one efficient system to cool down substrate.
Here's my crude drawing of how I think this can all work.
The system could be gravity fed as per Arathu's idea but would likely still need a water pump to return water back into the loop. Fortunately the pump used will almost certainly draw under 1 amp, making it easy power through solar and battery if one desires. In theory the system itself should be much cheaper to run than an ac unit. Usually with geothermal systems for every $1 of energy used you would get 4 or 5 dollars worth of heating / cooling.
Hdpe tubing or copper tubing ( or both)
Some sort of foam insulation
Silicone to seal everything
I have a feeling that whatever the fruiting chamber is may need to be insulated further but maybe not. The way this design works the coil in the fruiting area cools down whatever is on top of it. In this example it's an aluminum tray which works similar to a heat sink and cools the substrate considerably. I think that because any further transfers would pass through the substrate that maybe and this is still a big maybe, the substrate will remain cool even if the surrounding air is not.
At some point I will edit this from a computer and try to put everything in a more logical order, I'm just trying to cover a lot of stuff at once right now.
Let's come up with something great y'all!
