That's pretty awesome. I wonder how well it works in the summer.

Depending on location, ground temperature tends to stabilize once you get a few feet down. Here in the northeast United States, it's about 60 F year-round once you get 15 feet below the surface.

I worked for a company that was making direct-exchange geothermal heat pumps for homes - think about a big refrigerator whose coils are buried in the soil.

(About 15,5 °C)

15 feet sounds pretty deep to dig to install something like this. Any idea what the temperature is like 2-4 feet?

Is that cold enough? My fridge normally about 1-4 degrees Celsius.

That's going to vary a lot more by location, and 2-4 feet puts you at much higher risk for your beers freezing (although if you fully load this with beer, you'll have some beers at 2-4 feet anyway). Where I live, for instance, beers will probably freeze 2 feet below ground in winter. But my well is down below 15 feet and is always liquid.
