The temperature has been holding very well. I have a case of full bottles and a few other items in the chamber now, so it isn't just empty. The fridge powers on when the temp reaches 20.5°C and turns off again when it hits 20.0°C. This takes about 5 minutes. I haven't timed how long it takes between cycles, but really haven't noticed it coming on much at all. I still need to add a heater inside before winter is here, but thankfully George RR Martin writes slow enough that I can brew another batch before then.

I'm brewing this weekend, so this will be the real test.

Beautiful craftmanship GPSaxophone. I bought the materials to build one myself today. Based on your design and several others. In one thread, someone mentioned not to enclose the fridge because the sides get very hot. Are you having any heat issues with yours being enclosed? I like the fact that it's enclosed, but worry about the fridge getting too hot and possibly causing damage and shortening the life of the compressor.

Very nice work. Make sure that there is good air flow behind that fridge and it should work fine.
What about condensation? Most dorm fridges have a drip pan that doesn't hold very much. If you use a set point of 16C in the summer (that is where I leave mine) then the compressor will be running a lot and making a lot of condensation.

My fridge doesn't have coils in the sides, they're all on the back. As a result, the fridge sides don't get warm. The back of the fridge (on the side of the chamber) is open to my workbench, so it gets plenty of air for the heat exchange.

I have checked the drip pan inside several times, but haven't found any condensation in it. One reason is that the fridge doesn't come on very much, partly because of the insulation, and the other is that Colorado is a very dry (arid) state. It helps us out in the winter by drying out the roads after it snows, but has its downsides as well. Wood instruments (like guitars) dry out and crack much faster here than in other places.

I took advantage of Labor Day to brew a Blue Moon clone that I found on the forums here. It smelled real good while brewing, especially after adding the orange peels and coriander. Here's a shot of it in the chamber:



I'll be brewing a pumpkin ale in another week or two.

Ok, thanks. Good to know. It appears that the entire fridge is enclosed. My fridge is made the same way, all coils in the back.

Just a word of warning - just because you have could on the back of the fridge doesn't mean that they're all on the back. Mine has them on the back and also some on one side.

You can test it by turning it in and then feeling the sides and top for heat when it's running. And/Or, you should also be able to see the lines as they run out and into the compressor and see any branches, etc. That lead under the sides of the fridge.

Just checked my fridge. Coils are on the sides too. So to ensure the sides get enough airflow, I'm going to borrow this vent idea as seen in the pic. No, this is not mine. I wish though, lol. Do you think if i install vents on the sides and the back, it'll get enough airflow? Thoughts and ideas would be appreciated.

Vents like that are probably going to be OK. A lot of refrigerators are pushed up against a wall even though there is supposed to be 4-6" clearance. This would go for the sides as well if that's where the coils are. If you build a solid cabinet for your mini fridge to sit in you may need venting (like you pictured) or even a fan to allow for adequate heat exchange without shortening the life of your fridge. I was lucky that I found a model that only has the coils in the back so this isn't an issue for mine.

It's not just the life of the fridge - its capacity to cool can be affected too.

I think the vents are a good idea. Try to set them up so you have convective airflow
