I think the reason his works so well is becuase of massive subcooling. There isnt 2 hx's on a 3 stager for him. There's just one giant HX.

Damn nice results ! So did you went with "green" gases or the r123,r22,r23 and r14?Quote:

It's not green yet. Yes, I have an expansion tank with a captube.;)Quote:

Actually, there's 3 separate HX's on the unit - 2 cascade condensors and an aux. condensor.....Quote:

H*rny unit there.. from what i have heard.. youre a impressive great guy !!
Help us amaze in u ;)
Check your Email......... then look at post #7 of this thread.Quote:

and what about the solenoide... whats its role in the system?
what gas is the aux cond cooling? :D
Where is the solenoid...?
Anyways, few uses I could see for using solenoid...
#1. bypass for gas.
#2. enabling and disable certain stages to aid in pulling down to temperature... and depending on gas, shutting down certain stages to keep it above freezing point.
#3. connection to expansion tank.
Hmm... solenoid do sounds useful on complex system after all.. :P
So where is it and which is it for? :P (I still haven't seen the pic with solenoid in?)
as far as it seems the solenoide seems to control the flow to the aux cond
now, what controls the solenoide? a thermostat? or a pressurestat ?
so the aux cond only works to start off the system?
hehehe lots of doubts...
Couple of questions:D
How did you make the phase seperators and how did you make those heat exchangers?
Still like to see pics of the whole system too;)

John.
yeah i want a picture of everything!
what is your evap like and what kind of load does the unit hold?
Ummm...didn't he send you that schematic AFTER you had posted? I'm not sure what he showed you, but I thought you were talking about the unit he initially posted here. BTW, I saw this unit running in person yesterday and it IS everything he's claimed it to be - and MUCHMUCh more :cool:Quote:

@ Jin: It's in the pic, towards the bottom of the unit
@ Rev: The "evap" is a "cube"-like box which resembles a cryo-chamber of sorts. The unit was able to bring the air temps in the chamber down to -85C.
Oh, btw, the solenoid is used to turn the cooling on and off for the cooling chamber. It's connected to a manual switch.
Sorry different diagram I was showed.
I know of the diagram he showed you, I'm just trying to clarify what we're talking about :p:Quote:

Hehehe..no need to...he's already playing with my polycold ;) Currently @ -136C and dropping :slobber:Quote:

I am, aren't I :p: All credit goes to cryo-tek though. He's simply brilliant. I forsee a new thread coming....;)Quote:

Sounds pretty neat :D
hey cryo, what kind of load do you have in that box?
thats magic cryo-tek.
can you do a basic drawing of the hxs.
i got some copper tubing today and thinking i want to make a hx similar to that.
Seems we all got something to learn. ;)
