Default Brute force lagering

Long time lurker to this area and I've learned more than a few things, so here's my contribution. Here's my ghetto(but free!) test rig for temperature control. Basicly it's the evaporator of a window AC unit imersed in a bath of water along with a heater core. Then water is pumped through the core and into a bucket surrounding the carboy. I had all the parts lying around, and my last batch hit 78 degrees even with the fan and tshirt method, so this is what I came up with just using parts I had lying around. I've been able to hit the mid 40's without really trying and can maintain 68-70 without any trouble on the stock thermostat. Next up is a real controller for it. Not sure yet if I'll use a comercial product or just arduino it. The plan is to put the AC unit in the garage but be able to pump the water into a seperate room/enclosure.

It looks fantastic, no problems with the electrics being so close to all the water?

I might be missing it, but why not just put the evap coil in the same water batch as the fermenter and forgo the extra heat transfer and use of electricity to run the pump?

First the electronics are completely enclosed so no risk there, I haven't altered anything electrically and won't have to since the thermostat has an "always on" setting.

Second, you could do that, and I might be doing that in the future, but I didn't have a tub big enough to do that nicely. The caveat to that is you need something to either circulate the water around the evap coil or to draw it's lack of heat away in order to prevent the coil from icing up, for instance a mid 70's chevy heater core. By itself in a water bath it will encase itself in ice relatively quickly. What I'm really toying with is moving the cooling source from the carboys.

Expansion to multiple controlled temps off one cooling unit, that's why

That's certainly one possibility but we're talking about running each pump on its own controller. That's a lot of work ;-)

in the overclocking world(computer) this would be called phase change/chiller. instead of water, you can try using coolant to prevent frost buildup. this one guy i know uses denatured alcohol (yes, its flameable, but its kept closed system).

all in all...this is not a bad idea!
