Showing temperature is just pointless, without insulation temperature really sucks, with it it will be around -75 (now with CO2 for testing).

24°C gain only because of insulation??? :eek:
Which iso do you have bro??? :D :D
btw: damn nice unit! ;) Especially if you look at the time you have to build this beast! :banana: :woot:

So this is C02 currently?

Yes

"only insulation", I wouldn`t call it in that way :) I don`t wanna quess, but those HX are under air load, which is about 100W or more

Yes, finally it will be R290/R23.

This is ONLY I stage ! :slobber:

Nice unit, just looks very good and clean :)

i reckon that r170 or r1150 will do better with r290 than r23.

what do u guys think????

yes, it will be better, but to use R1150 would be needed more "difficult" autocascade :)

R170 would be great to use with R290, but from what I know, R23 can move a lot more heat.

You got school or you building today then dude? It's looking good so far.

I'll get my evap off to asap

yeah r23 has double the mass and 290 and 170 may mix too much don't know where, here on the forum, i read it.
what about oil???isnt is freezing? how are your autocascades doin? i mean there is the normal oil, u said in 1 u used mineral in other 1 u used poe, no problems???

thx and good luck

No problem with both oils, with poe and mineral. Now at I stage I`ve got AB oil (don`t know how to write it) and no problems.

I was at school, now I`m back. Today I will build small wooden box around HX and fill everything with foam.

:D


Go, go Lukasz :toast:

AB (Alkyl Benzene) = Mineral Oil

ooow luke you build the cascade very fast, i think u need some rest..........

I`ve bought already some wood for case, now I will go to my workspace to build box for HX and will make two oil separators :) Stay tunned, more photos soon !

:toast: PICS :D

Luke you work fast dude, fastest builder on XS with then added professionalism :clap:

Mental suff Luke, school, working on this, everything. Your a machine

I`m sorry, but no picks :( Marta needed camera, so no photos today.

I almost have done wooden box for HX, filled everything with foam, started cascade and I magically saw -71*C (R290/CO2) with 0,5bar suction pressure :D Very good :D Tomorrow will instulate all pipes (need to insulate properly whole I stage) and fill with R23.

Tomorrow I think that I will finish stage II.

Can plate HX be placed horizontaly ?

It doesn't look kinked to me :). Just very small hehe :D.


Luke, i'm not 100% sure but I don't think there would be a problem mounting plate HX sideways.

better place it horizontally to be sure that all of the refrigerand boils off in the hx. otherwise it could happen, that the flow "sucks" the liquid refigerant into the suction line and you loose capacity!

any progress?

better place it VERTICALLY or the above will happen, not horizontally like he has it pictured.:nono: :)

Ok, will place it vertically.

II stage almost done, today I hope I will finish all stages and show final, III stager temps.

Don't forget photos Luke!!
