Only -150? Triple stage might manage -200
Show me. -150C is pushing it.
I'm working with fully adjustable valves i've modified, should let me get a range to fight coldbugs, as well as a hot gas bypass system for the really warm boots.
Other than the coolness factor (heh), what's the point of refrigeration? Seems like a lot of work, and a lot of power usage for a gigahertz or so of overclocking.
Man I wish I knew even a little about HVAC to understand what im looking at in that cad.
The point of something like this, or of Ln2, is to push the limits of overclocking, and take over some top HWbot spots. A fully stable system like this that can go this low, can possibly beat up an Ln2 system.
So I assume this has the capability of running at low temperatures for extended periods of time - compared to Ln2 which requires top-ups?
Good luck with it and I look forward to seeing the results
Well You know more than me, I was just going on what I've read previously.
With the adjustable valves, I might be able to see as low as -160C with low to no load and a light charge, we'll see. But yes, I will be able to have this run 24/7 (though will hit the power bill if I did), and not have to top it off or what not. And have more stable temperatures. Ln2 you can be pouring every 5 minutes!
bloody hell man, this is going to be one awesome setup.
I've just finished a module in thermodynamics (exam on wednesday, wish me luck), even though i'm no expert, this kind of system is really worth a lot respect. I'll definitely be following this.
Best of luck
oh dear god
talk about a cold chip
how does all of that work?
Standard refrigeration cycle on the first stage. It chills a heat exchanger that serves as the condenser for the second stage. The second stage uses this cold condenser to condense a higher pressure lower boiling point gas after straining it to remove oil (which is recirculated to the compressor). This second stage then chills a second heat exchanger stack, which serves as a condenser for the third stage's EVEN colder boiling point refrigerant.
All stages will be equipped with safety controls for pressure, digital temperature displays, automatic turn on and off for stages, and the third stage features and oil less hot gas bypass, allowing me to warm up the third stage separately of the first two.
Small update, milling machine is stripped and in the basement, going to give it some red paint and rebuild.
Some fairly sloppy grinding and heavy red krylon paint later,
A milling machine! Richard got it into the workshop on this dolley of his. I was scared watching this thing jump up and down with each step. (Had to underinflate the tires on the dolley to take 300lbs safely)
Im I´ll keep visiting this thread, nice cad art.
I like that, milling machine on matching sack trolly haha.
I'm tempted enough to build a phase unit onto it. Would have to get a tiny bit bigger tires though so that I could sneak some rubber stoppers below the main piece.
Would be pretty cool though?
Welding up a new work table, mainly for the project, but also for the milling machine.
Then we can start plotting the cage
I dont know anything about this stuff but it certainly looks very impressive
