my 3 stager!

hi ppl my 3stager project start finaly!

it will be a 3stager cascade, maybe r410/ethylene/r14

i want the sweet point of cooling conrroe

1º stage :D :

compressor n13 from this page:
http://www.chinagmcc.com/product/swage-x2c.htm

13 000BTU ;)
how mutch this is in horsepower +-1.5 ~ 2hp right? :D

i'll use condensor to condense 1st stage and desuperheat 2nd and 3rd stage!
and this fan to cool condensor and compressors!

stay tunned
:toast:

13000 BTU depending on the average heat rating for that btu would probably be just over 1hp.

Refrigeration Basics -

Long ago it was found that we needed a way to quantify heat. Something more precise than "less heat" or "more heat" or "a great deal of heat" was required. This was a fairly easy task to accomplish. They took 1 Lb. of water and heated it 1 degree Fahrenheit. The amount of heat that was required to do this was called 1 BTU (British Thermal Unit). The refrigeration industry has long since utilized this definition. You can for example purchase a 6000 BTUH window air conditioner. This would be a unit that is capable of relocating 6000 BTU's of heat per hour. A larger unit capable of 12,000 BTUH could also be called a one Ton unit. There are 12,000 BTU's in 1 Ton. :surf:

I bet your new rotary does what you need it to do.:)

Sounds fun and evil... lol... looking like a good start...
More I think of it lately, it might be just cheaper to build cascade base on cheap AC unit out there than to start new one from scratches -_-; (granted the noise doesn't kill you ;P)

dont know if 410a is the best way in first stage , but good luck ,

i have many of this baby rotary toshiba :D

nice comps

Arggghhh, you first started your 3 stager ! :p I wanna be first, hehe :toast:


Yeah, Ricky, I would try with other gas in I stage instead R410a, don`t know cooling capacity of R410a, but I think gas with just little bit higher boiling point would hold load better.

hummm ok, i'll give a try. if no good, r404a will do the job, or a mix

What you looking for unloaded?

I think he is looking for -130c below for underload... I mean... quite a few of us can make cascade idling -130c... with nothing on and no tuing :P

r410 works good as long as you got a enough big condenser.. that's often the problem with those small units. to small condensers.

[edit]
you are thinking about the nature.. a RoHS classed compressor :D

I'm looking forward to see how this turns out :) How much does that air conditioner cost?

-130 load maybe impossible,
anyway,take a look on lukexe awsome autocascade/cascade, -130 idle -115load on -55 to -65 range on hx right? on -95ºc hx maybe will have some gains on r14, so it must dont be hard to get -13x idle

r14 boils @ -128ºc right? on -95hx and good compressor maybe can work on vacuum, but only my ideia, no tecnical basement! as always, trying will tell-me!

anyway the ideia will be to cool an conrroe, not for pics, i'v seen some with cold bug arround -110 i'll test


skirms_fr, i'll like to get more details on that cascade, any links? :)

my ideia to test r410 is becouse condensor and compressor seems to be ok for that.

:toast:

Good luck Ricky :D!

Skirms_fr...that red unit looks really unique!

|RickY| maybe you will make a autocascade on 3 stage (r14 and argon mix)
maybe r14 and crypton?? :)

Duniek, a r14 argon mix WOULD NOT be an autocascade.
There is science to the argon r14 mix thats a bit hard to explain, Ricky i added your msn, I'd love to chat sometime.

In an r14 argon mix the argon does NOT condense.

cool :) i'v read some things about that mix, the problem is the rare and expensive r14 is to try mixes :S

anyway.. who knows! hehe

well, i'v prepared the a/c for what i want, tested compressor :D

my lover :D

just to check +- measures to desighn the cascade and the box of cascade:

http://img124.imageshack.us/img124/9...rementsuk7.jpg

well i fill 2 bootles like that with r407 that comes on the a/c, but this one dont andle the vacuum lol my heart almost stop when the botle turns to this, like a BOOM haha

thanks and :toast:

Hop me a message sometime ;)

Yeah r14 is a tad expensive (tad lol)

no link for the moment :)

just on my ftp :)

i m just waiting for R14 , i have a little R170 in a bottle , and waiting too for R1150 :)

maybe gonna test with methane in third stage, i ve put relief valve on second and third stage:fact:

Hurry up my friend, these new toys are ready to jump to your new CPU cascade..

http://pedrorocha.planetaclix.pt/SLI_ready2rock.jpg

I'm sure my partner in bench will managed a cpu cascade with the X6800 "sweat spot" : around -120ºC load temperatures (the cold bug frontier) :D

With the 2 8800GTX on Ricky's good old SLI cascade, we may get interesting results ;)

Party almost ready to begin - gonna be fun and entertaining as always was my benching sessions with Ricky:party3:

Ricky, I'm sure that will be kickass :slobber:

Maybe You want to buy some "fitted" PG165 10000BTU Toshiba rotaries ?? :D YGPM

Goodluck :)

Regards
Peter

i remember someone getting angry and saying that a 13000 btu window ac is exactly 1 hp.

the argon thing cryo-tek was talking about on the polycold build.

It can! just because theres a chart between Btu rating and HP rating doesn't mean there exactly on. What im saying is a 1HP compressor can range from 10000Btu's to 13500Btu's. It just depends on the size of the compression parts inside the compressor and how its built.

From what i have learned these numbers can be trusted:

5000-5950Btu's-1/3HP
6000-7500Btu's-1/2HP
7500-10000Btu's-3/4HP
10000-13500Btu's-1HP - 1 TON
13500-16000Btu's-1 1/2HP
16000-20000Btu's-1 3/4HP
20000-24000Btu's-2HP - 2 TON

1 thing ricky that looks :banana: :banana: :banana: :banana:ing big !
