Help with Refrigeration for a (Very) Custom Bar Top
The gist of this question is this: How do I calculate the size compressor rig that I need for a cooling system? The larger context is this: I am building a bar in my living room that has some special features - Namely it has a "cold strip" running across the top of the bar - which amounts to a 4 inch wide strip of chilled copped built into the bar top- to keep your drink cold; as well as two vodka wells - which each hold a bottle of vodka in a frozen bath of (cheaper) vodka (under a glass dome).
The bar top is made of Styrofoam and composite materials (I used to make Surfboards) and is basically seamless. The copper tubing will be built into the bar top - under the composite and soldered to a copper plate - which is built into the composite.... you get the picture.
I have built "frozen" sculptures in the past using old fridges that I have disassembled and then re tubed. In the past I have always just winged the amount of tubing I used and thus far - have gotten away with it, and the sculptures have always worked. This time though I am buying the compressor new and want to match the unit to the need - but I have no idea how to calculate the needed compressor to the job. Any help would be great. Thanks!
And Yes, I will post the Instructable when the bar is completed. :)
