Hello All,

This looks like it was once the hot place to be for phase change cooling I wonder why it seems to have mostly died off?
Anyways, hopefully some of you are still around who could lend me a helping hand.

I'm working on designing a case. It'll house computer and single stage unit as well and some basic controls. I've made sure it's a little large for potential upgrades down the road. I'm still learning right now, but at some point in the future, I'd like to have a 2 stage cascade system.

I currently have a compressor, condenser and I'm in the process of getting a chilly1 evap from Ron (heard great things, so I'm excited )

So, question 1.
I noticed on some builds, there'll be tons of coils of copper, like on overklokk's two stage seen below:

What is the purpose of this? Why do some builds have this and some not?
In a build guide from overclockers.com, they put a single loop in the copper pipe in order to dampen vibrations coming from the compressor. I assume there's a functional reason for these coils apart from vibration dampening?


Question 2.
How do you go about determining how far you will run a compressor over spec?
For instance overklokk was running two R134a compressors with R507(I think) and R1150. Now, I probably wouldn't want to go grab any random compressor on ebay and load it up way over spec. So what are you looking at to determine if the compressor will handle it?


Also, any words of advice for my first time building a phase change system?
