I have constructed a keg cabinet as part of my bar in my basement and am trying to figure out how much refrigeration I need to keep my kegs cool. The cabinet measures 27" H x 40" W x 24" D and has 1.5" of pink Styrofoam insulation board on all sides. I read Chris Bible's article in this month's BYO and calculated that I need about 400 BTU/Hr to keep the interior at about 35 deg F with an exterior temperature of about 75 deg F but this seems like a low number. Can anyone tell me if this value is in the right ball park? Also, I am trying to decide whether to use conventional refrigeration or thermoelectric. For conventional, I am looking at a remote condenser unit off to the side with an evaporator inside the cabinet. A thermoelectric unit could be mounted directly to the side of the cabinet. Any thoughts on pros and cons of each type of system? Can anyone suggest a unit that can provide the level of cooling that I need at the above temperatures.
