Do you know how much energy you are using on the dorm freezer? Also do you thing you run a risk of killing it prematurely trying to cool that large of an area? Have you installed any fans to circulate the air to reach a more consistent temperature through out the chamber? Have you checked the temp close to the fridge and then on the opposite side? I was thinking this could be great to keep different beers at different temps. I understand if all of the seals are good the chamber should equalize and all be the same temp. Just wondering if you have seen any difference. Thanks!
I don't know how much electricity I'm using for the freezer, but we haven't noticed a bump in out utility bill, so it appears to be nominal.
I do not have any fans in the cooling chamber. I had expected that I would need to install some, but once I set the Ranco and saw the results, that was good enough for me. I over insulated the cooling chamber, then wrapped it in frp and caulked the heck out of every joint. I have no cooling loss that I can speak of, and the temp in front of the varies by *at most* 2F from right in front of the freezer to the other side of the chamber farthest away from the freezer.
I believe that the key to a project like this is proper insulation. Once you have done that, you are able too eliminate many other factors.
