Luke did you know I,m 100% polish my grandmother(moms side) was 2 when she came to USA with my great grandparents,on my dads side its was my great grandparents that came from Poland.Maybe our blood lines have crossed some where?
Luke in my opinion while you are getting results,way to much is on a dangerous experimental basis. I and I,m sure your girlfriend wouldn't want you hurt.
I personally believe you are trying to progress to fast,chasing that low number and don't have a through understanding of theory and how specialized components work.
I wish you would buy that book I keep recommending and start reading till you have all 1000 pages plus memorized. It will make you a much better builder once you have a much better understanding on how complex refrigeration is,especially cryogenic refrigeration and their controls. I sure hope you take this advice. Anywhere from a 80's edition forward will help you tremendously. The newer the edition the more you will pay. $5.00 to $75.00. It's a college level book but written so it can be understood by high school students,It may even be used in some high schools. Many illustrations to help you understand.
