...and I've start evacuation of 1st stage :). Tomorrow I hope to see first frost on pipes ;).
Best Regards

Your piping skill is improving massively :)
very nice peter :)
how long do you make the 0,9mm cap tube's on second stage?
in my rotary gpu cascade i have a lot of problems with the load. i think the cap tube is not perfect. must change that.
no leak testing before evacuation? ;)
Heh I've just bought pipe bender ... ;)Quote:

Hi again :)
@toaster, one more : "not perfect" lenght of captube doesn't change pressures MUCH , for instance 15 cm too long captube doesn't rise You discharge for 3-5 bara more ...so that is not a problem here in You cascade .
Next portion of photos, cascade was filled with R507 and R23 today (pure R23 on 2nd) ... :D

http://www.members.lycos.co.uk/piotres2/sc18sli/51.jpg
first frost on here pipes :D and -48C on 1st stage for "welcome" ..with insulation on HX made of old cloth LOL :ROTF:.
http://www.members.lycos.co.uk/piotres2/sc18sli/52.jpg
more frost ...
http://www.members.lycos.co.uk/piotres2/sc18sli/53.jpg
After a little tunning for load, with no load both heads was around -75C :) .
http://www.members.lycos.co.uk/piotres2/sc18sli/54.jpg
And that's with 485W total on heads (260W plus 225W dummyloads) ..a lot of heat put on danfoss hermetic 5/8 HP ;) . I hope to gain few *C after insulation . I want to beat -60C with this load, and test it also with little smaller load (like will be used in "normal" benching becasue 260W dummy is .... killler load , I'm sure any GPU now doesn't produce so much heat :rolleyes:) ... :cool:.
http://www.members.lycos.co.uk/piotres2/sc18sli/55.jpg
Temperature of 1st stage idle and pressures in 2nd stage idle.
http://www.members.lycos.co.uk/piotres2/sc18sli/56.jpg
Pressures 1st stage idle .
http://www.members.lycos.co.uk/piotres2/sc18sli/57.jpg
Thick froooosssttttt :cool:.
1st stage compressor "holds" me a bit, with rotary there I can gain some *C, now with 485W put on 2nd stage, first stage is only sth like -22*C . For R23 that's still fine, but could be better ;).
Thanks
Best Regards
Peter
wow very good
