I have a Beverage Air 3 door kegerator, and it's an older r12 unit. I am planning on checking the r12 soon, it keeps the beer cold enough but the thing runs most of the day. It takes some longer breaks at night. The problem is that it's on the back porch, and I live in TX. Insulating the towers on the outside has helped some, I used some windshield reflector material (foam surrounded by shiny silver stuff) to make a jacket for each tower, it has almost removed any sweating issues. I know the bottom outer plate of the unit is compromised because when I moved it, a lot of it fell out in my truck. It sits on my back deck. I planned on adding some R panel insulation on the inside of the box, to help it keep it's temps against the outside temp. Is this a worthwhile pursuit? I bought 2 4x8 foil lined foam panels, 3/4" thick and R value of 5. Once I got them home, I started wondering how this thing is assembled, where coolant is circulated, etc. I would not want to block where the cooling is coming from. One door seal is not the greatest, but I want to solicit some opinions about this before I go cutting up some panels for no reason. I have plenty of room in there so I'm not worried about that. Here's a pic of kegerator when I first got it home. The cooling coil is not visible on the inside, it's concealed.
The inside looks kind of like this one, with an all metal interior and a fan assembly on top http://www.micromatic.com/images/gal...3-2_o_600x.jpg
any feedback appreciated-
