I know

Now I'm actualy rethinking about doing some phase change in the summer vacations.
Dunno wheter I'm going for a waterchiller or direct die, but first I'll have to find a job for the weekends (to buy a sweet A64 setup :grin: and then saving for the PC stuff)

Maybe people are interested in Autocascades and Multiple Stages Cascades?

I think it's pretty interesting, so I figured some people @ MadShrimps would think the same

Not simple tough, but multistage rules :grin: -128° load

- 159°C Idle :grin:

I agree with you on the multiple stages
but the autocascades seem pretty tempting

but first need to complete a 'simple' single stage

Autocasced seems not so easy. I've read about it long time a go.



Ok, let's see if I can remember, the black thing is the compresser, the red line is the discharge line, where the refrigerants leave (as a gas).
The first radiator (condensor), is where the first refrigerant will condense, the other one will stay a gas and wil move on at the top. The thing next to it will prolly make sure that the 2 gasses will split.

Then the blue refrigerant will go throug the cap tube and cool the condensor (using an evaporator) of the second (red) refrigerant.
The blue refrigerant returns to the compressor.

The red refrigerant (wich needs the low temps to condense) will turn blue (in the pic ) and then go throug the cap, to the evap on the cpu and will then return.

I'm I right or did I make a mistake ?

To me the only advantage of this is that it's compacter, but it needs a strong compressor (doesn't save money), it's complicated, ...

i think the main reason of this installation is that the liquid that enters the cappilair is chilled by sort a second loop

edit: looked in the topic and what did i find, guess i was right

kristos asked me to explain all the components of the tristage-cascade so here it is

@ Autocascade

It's a bit more complicated than a normal single stage.
You're right about everything and the 'thing next to the condensor' also servers as an oil reseptor or how do you call it, so that there wouldn't go any oil in the evaporatorhead.

You don't have to buy a new compressor for this kinda stuff ha.
If I could find a 3/4hp compressor or something I'd give it a try someday. But I'd rather build a single stage first
Also, gasses can be cheap. (how much will propane and CO² cost you?)

It just seems ... ingenius...(if that's correct english. it should mean 'ingenieus' )

anyways, keep up the good work

catch ya later

kristos

need someone to double check:

9000 btu = 3.537pk right?

jort

2637 is what i get

1btu =>0.293pk
edit=>1 Btu = 0.293 W
