Hello everyone. Just figured I'd introduce myself here. I'm kind of between junior and senior year studying for mechanical engineering, and find most any engineering topic, including refrigeration, very interesting. I'm also quite mechanically inclined, esp for car repair and custom fabrication. I've come across good threads here on hvac talk googling for information in the past, so I decided to join for full access to some good tech reading.
I work at an ice rink for about 3.5 years and counting, and keep an eye on a pair of York millenium reciprocating liquid chillers...just logging readings and telling the pm tech when things don't sound right, but that's kind of spiked more of an interest in refrigeration. I'm definitely the hands on type, really like to learn how things work, and like to fabricate custom projects to do so. I got my 608 type I certification a few weeks ago so I can legally tear into some small scale refrigeration to learn more about it (currently found an old R22 dehumidifier slated for a project that definitely won't live in a little plastic box on wheels). I'm also hoping do do a project for senior design in a year that will involve building a small liquid chiller for a working scale model indirect cooled "smart" ice rink slab project. I'll try to keep the "will an R22 compressor work with an R12 TXV, pumping R152a with mineral oil?" questions to a minimum, but may post some more general theory based questions if I can't find it here already.
