Exhibit Hall #2 : MoRf-- The Mobile Refrigeration System

Disclaimer from Mark Lagus's Ph.D. Thesis (p.120)
I still remember its origin. During one of our group's twice daily daily meetings, Professor Anderson turned to me and said "why don't you look into getting a compressor or something to refrigerate the baffles." Not knowing anything about compressors or refrigeration, I quite reasonably wanted a 'black box' off somebody's shelf that could be hooked up to our apparatus and then ignored. In other words, I never intended to create an entity; I never intended for it to have a name.

But it does. MoRf is a two stage vapor compression refrigeration system chock full of ozone destroying dichorofluoromethane (aka Freon, R-12). MoRf, however, is not a failure (at least for the moment). Instead, it is a success story-- a shining beacon of hope, all alone in a lab of despair.

name of piece: Compressor Mounting Flanges
artist: Mark Eriksson
date of acquisition: 1991
description: "Three strikes and you're out!" Luckily, the third flange in this series was a hit. The first was made precisely, but to fit the wrong size pipe. The second was designed for the right size, but suffered a fraction to decimal conversion error on the lathe.

name of piece: Oil plug Adapter
artist: Mark Lagus
date of acquisition: 1991
description: This brass adapter had a small leak between the central threaded adapter and the cylindrical spacer. After a terrific silver-soldering job, the threads disappered.

name of piece: Swageloks®
artist: various
date of acquisition: 1991
description: A collection of Swagelok® joints removed from the mobile Refrigeration System. Evidently, silver-soldering changes the temper of the copper tubing enough to prevent proper swaging. Luckily, their high price prevented more from being used.

exhibit on loan (?)
name of piece: Copper Tube
artist: MoRf
date of acquisition: 1993
description: From Mark's Refrigeration Notebook (p.39)
My often-neglected refrigeration system must have gotten lonely. It pulled one of those vent-my-refrigeration attention getting tricks. Yup, the oldest one in the book. As it turned out, the 3/4" intermediate line had been rubbing the smaller heat exchanger for quite some time and had finally worn a hole thru the copper pipe! (It took a hell of a time to finally check there and find it).
