Default Peltier kegerator

Some pics of my new cooler. Its gonna be cooled by 4 136W peltiers.

Here is the front. The top are gonna be covered with tile and then the taps.



Not finiched yet on the inside. More insolation on the doos an some plsatic on the floor. The auminum sheet on the back is gonna work as a heatsink on the cold side.


The peltiers are gonna be mounted in the aluminum blocks. The outer block is watercooled and a radiator is gonna exchange the heat with a little help from 2 120mm fans


I will have a nice dark colour on this furniture, that I hope gonna serve me cold beer for many years.

Nice setup! I did a science experiment around 2000 using peltiers to cool my PC. It was a fun project and peltiers are pretty neat to work with.

What did you control the temperature with?

Expensive way to cool a kegerator. Peltiers are not very efficient.

Keep us updated.

yea. neat project, but its going to be very inefficient.

the way to get efficiency out of peltiers is to cascade several and undervolt them all. even then, you wont break 50-60% efficiency. a single peltier is usually 20-30% efficient, depending on quality.

So what? Its not that they are going to burn 400W 24/7 the year around.
And still half the year I will have the heat inside the house.
The fact remains that cool boxes with peltiers work. Exactly the same thing.
And well, its cheaper to buy the beer in cases of 24.

But as a defence, I dont have the space for another refrigerator in my livingroom, and build this with a compressor from an old fridge was not an option. Its not cost efficiant.

With this said, I dont care if its expensive to run my fridge as long as I cold beer. And I built it myself!

Are you going to cool the "hot" side of the peltier?

Yes. They are water cooled. I cross drilled the outer aluminum block.

Looks pretty cool! I'm interested to see how it turns out for you.

I want to know where you got the thermoelectric elements, and what the specs are.

I have thought about making an absolutely minimal kegerator for a single corny, using a thermoelectric element applied directly to the keg. But I have never found a source of thermoelectric elements.

One of the benefits of these type of coolers is that they can be absolutely silent, which I really like. In your case you will have some fan noise and water circulation, but that can be pretty quiet.
