my new unit (-71C idle, sc21cl, slhx, cpev etc,) lots of pic

This unit is prepared to work with big loads.

Evap is the same i always use, chilly1 design but a little bit modified. (I've bought a few about year ago). Suction hose is about 1,2m long.

You can see polish coin on the polished base here *)

now some pics of parts used in system (sc21cl compressor, slhx and 1,9kW condenser)

i've put switch and fan regulator to the starting device

here is pic of slhx with cpev and suction side accumulator

and first run temp, ive used r507 and 1150 mix so temps were quite nice, about -65 to -70C at +0,4 - +0,5bar on low side so there was high refrigerant flow. But i wont use this mix (too high pressures on the high side - 25bar/350psi), maybe i'll get r23, it would be better i think.

i dunno much about load temps, i should test it this week

overall look? well you should like it, maybe besides insulation but it is 19mm thick on suction hose and even more on slhx. We dont want to loose any performance do we? :lol:

now some pics, i hope you like it ^)

so what is your opinion :>?

Holy ****! :slobber:
This is one of the best SS's I've ever seen! :banana: :toast:
So ... WOW .... just awesome! :)
I'm building a similar unit atm! ;)
It's based on one of your NL11F units which I bought from another polish guy about 3 months ago! ;) :)

woah very nice

is that compressor beter then nl11F?
greetz

hey dude, gr8 temps!

sc21cl is about twice better than nl11f but with load, there is no big difference in vaccum i think

i'm glad that you like it :)

Wasnt this also the same plan of HL4E ? GREAT work man!

Nice , wait to see some load's with this single beastie .

i must buy some resistors for dummy load, 180W should be good or you want to see something more crazy? :P

Well 200 would be nice :P

very nice unit RaVeN155. awsome temps!
but i have one question! how do you seperate the two phases?

:woot:

that's one of the finest single stages I've ever seen !

Its normal single stage, there is no phase separation, if there was temps would be much better but it would be called autocascade than ;)

I'm waiting for some r23 to test, r1150 isnt good addition, way to high pressures :)

Best single stage temps ever unloaded, in a nice and tidy package too! Any idea yet what it will do under load? How is the noise?

hmm im a bit confused. i see an HX (is it a Suction line one?). and a high pressure gas like r1150. how is the r1150 supposed to get condensed?in the evaporator?

Agreed :slobber:

you can test under load? :)

The unit looks really big and overkill...

i like it :D

esdee it goes like this

comp->condenser->filter->slhx->cpev->evap->slhx->sl accumulator->comp

so 507 is condensing in condenser and 1150 is condensing somewhere in slhx i think. Well i hope it work like this :P

but like i said, must get some r23 ;) if it wont work good i will do some tests with pure 507


btw ->mesyn191 it sounds powerfull, quite noisy than but not as much as rotaries

i will test it on my crappy cel D today but on pure 507 (waiting for resistors to do dummy load)

Raven, it's a masterpiece :D Great SS, waiting for some loaded temps :toast:

i've ordered a 3 resistors - 82ohm each so they should give me about 250W heatload (if my system wont hold it , i will kill it :P)

I'm checking results at 4,2ghz 1,6v cel D and on pure r507 idle temp is -47,7C and loaded (32mb pi) -46,2C. Cant wait to se some results with r23 because this system isn't designed to run in big vaccum (compressor is gas cooled so it need some refrigerant flow and slhx needs it too to work properly and condense high pressure gas)

Good work my friend :toast:

RaVen maybe test on P4 630 or 631 soon :p:

wow, very neat and clean job :toast:

A very pleasant work RaVeN155, congratulation ;)

greetings

Wow that's one of the cleanest setups I've seen, gratz on that man!

Not to mention those temps are insanely low, good job!

very nice unit.
How much the CPEV and the SNHX would improve your system ?
