Symphy`s 3 stager

So as I promised, new unit for Symphy, 3 stage cascade (with some extras from me, like I stage autocascading).

Compressors - 15800btu, 10000btu, 10000btu
Condenser - brand new 1,9kW
Evap - chilly1 clone, made by Duniek.
Gases - R290/R23/R1150/R14/Argon
Safety devices - two cut-off devices (for low and high side) and one relief valve.
Heat exchangers - two "pipe in pipe" HX for autocascading stage and one plate HX for R1150/R14.
Extras - maybe SLHX, expansion tanks, manometers .

Expected temps...For sure about -50C loaded on I stage, that should give me nice second stage temps and finally third stage temps too, so if everything will go in good way we will see -150C :stick: -125C loaded would be great.

evap not cleaned yet, I had really hard job with that sleeve because of insulation, which is...32mm thick ! Really crazy, but I want to minimalize heat losses on suction line.

The most important - safety. Two cut-off devices with auto-reset and one relief valve. Wdrzal :toast:

Expansion tank, I`ve got one more in my cellar.

Brand new condenser with fan. (lol, like almost everything, only 15800btu rotary isn`t new).

Three hearts of the system.

Everything together.

I must finish that unit until 9 of march, so I have a lot to do ! Probably everyone who want see that unit in real, just can go to CeBIT and see it.

Wish me luck guys, I will need it !

:rolleyes:

Good luck Luke, major subscription.

Insulation near evap is ...overklill :slobber: .

I don't think that LGs are 10000 BTU, rather 8500-9000 BTU :) .

I wish You luck :) .

Ditto.

I watch with great anticipation!

go for it Luke!

bare in mind that argon will only boost R14 below -105, methane would be better option for last stage

how many lts is that exp tank?

I think around 0,75l.

Subcooler ;)

yes subcooler works great, SLHX on the other hand are not so great

What model is it?

Looks like a very promising project! :toast:

Lg Nk134pad :)

It's a ~ 7900Btu/h... same one than my late second stage. I'll use it for a SS now. :)

Good luck buddy :toast:

its good to see you make somthing i will understand:D


i always like to see your work here


good luck you will need it 8 days left

this is going to be a nice system luke, cant wait to see the results.
I have that exact same plate HX :toast:

Okay, today I will do some most important job like mounting everything on black wooden base plate + some brazing, maybe today I will finish I stage (I hope).

My internet is down right now (f:banana: :banana: k!), so i can't read the updates luke will be posting the next days... damn :) I'm writing from the PC of a friend...

Hope everything will work like expected (within the time limit :( )

Looks very promising until now, and... i love the blue sleeving... :D

Good luck buddy!

Congrats Symphy on getting one of the best cooling devices for computers that Luke has ever conceived.

Nice stuff there, we are waiting to see -150°c ;)

regards

What kind of oilsep do you use? selfmade-> mapp bottle?

I wanted to use Temprite oil separators, but don`t have them. So probably I will make two from 35mm pipe (about 40cm tall).

Awesome Luke! Lets see -150c :D.

Ditto all the above Luke. That insualtion near evap is ugly as sin. I like the thickness of the rest of the suction line, guessing thats 32mm OD....?

I would defo change it, ether layer it nicer or cover it up!

Yeah maybe just move to a solid tube like donut, instead of tape.

Erhmmm....the rest of suction line`s insulation has 32mm walls...Near the evap I think it`s about 40mm, maybe less.

I think it`s ok, here is not miss world competition but xtreme cooling, we are at XtremeSystems or at Miss World 2007 ?

Should i chnage my name then Luke?? Miss World 2007??

Getto can be cool, nice getto anyway. I see blaster on his 2 stage rotary cascade has done the same but put some stuff over his!
