So I live in a very small apartment, and SWMBO has gracefully bestowed me with a single small closet to confine all my beer junk in. The result of this is that I have not the room to fit a refrigerator (or at least one that will fit my fermenters too), and I must completely DIY my ferm chamber. I am also too forgetful to use an ice-bottle method, so active cooling is needed.
To this end, I picked up a metal rack at the local hardware store, and have the insulation and heating pretty well decided, but I am stuck on the cooling method. Tokyo gets pretty hot in the summer (95+ F, 35+ C), so I need to get this set up within the next few months.
I had considered Peltier / TEC systems and Glycol, but TEC draws a crapload of power, and Glycol would empty my wallet, so I think they're both out.
Now I'm considering something like the cooling system on Brewgeeks, as I could fit a tiny freezer in the corner. My question is, do setups like this actually cool the chamber sufficiently to ferment or even lager during the summer? If not I may just tear the loops out of an old refrigerator and repurpose the parts.
TLDR: Do systems like Brewgeek's work well, or should I tear up a fridge? Is there an active cooling option besides glycol, TEC, and this?
