I'm thinking of building a portable kegerator to hold in the area of 8 to 10 kegs.
My idea is roughly drawn above... Have 2 pockets to hold Dry Ice and have fans to pull the cold air out of the pockets and circulate it around the kegs to hopefully maintain refrigeration temps (without freezing the beer!). Of course the box would be insulated, and I know it would hold temps. I'm trying to design something that wouldn't require the filling and dumping of ice and water. Put the dry ice in... close the box with a good seal and get it to around 38*... then put pre refrigerated ready to serve kegs in and re-seal it. I figure as long as it's not constantly being opened and closed it should hold temps.
I'm thinking my issues are two fold... testing to see how much dry ice it'll take to cool and maintain temps for about 8 hours, while making sure not to freeze the beer! I'm feeling confident that by keeping the dry ice in seperate compartments should help prevent freezing.
Ideas? Suggestions? Let me have 'em!
And for construction I was planning on building a plywood box, covering both sides with foam insulation (2"? Maybe?) Then once the structure is in place Fiverglassing the entire box inside and out where the foam and wood are 100% sealed inside preventing moisture and rotting. (Think Boat Hull!) Alot of details to work out... thinking 12v power supply for fans and 12v love controler w/ on-board self contained battery... maybe even put an external solar panel to keep the battery charged during festivities, depending on how much drain the fans and controler would have.
