Comment on THE SWAMP COOLER OF COLDNESS - diy usb aircon tutorial
rapchee@lemmy.world 3 weeks agoI have wondered how cool the ground is if you dug down 50cm or so and put the pipes there to cool down.
i believe a few meters down it’s a constant 10-15 °C, they do use it in “ground heat exchangers”, cool in the summer, warmer in the winter

A few meters down is a lot to dig with a spade compared to 50cm which is still quite a bit of digging really.
I do wonder what kind of temperature the water in a pond would be and if I could use that to dump heat into from my house.
