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. Walt
Nice to hear that wdrzal, you`re the polish man

About that book, I would buy it if it`s possible to buy it in poland, maybe you can help me with that and buy it for me, I will pay you and you will send it to me ? Hope it`s possible...

About ethylene, why I`m asking about condensing it in auto-c...the answer is simple, I want to have lower HX temps in my II stage cascade, to condense R14 with reasonable discharge pressures...Cascade is just finished but I`m still want to find a way to condense R14 in other way, safer way for all of us.

R507/R1150 autocascading stage would help me a lot to achieve lower HX temps under load instead of using co2 or R23.

And about membership in -xxx*C club, those words are about me ? that I`m doing "empy" numbers to just join to the stupid clubs ?
