Xtreme 2006 Autocascade Competition

[kayl]

Okey guys, gas for II stage is free, but we`ll play without r1150. So CO2, R23 and others are allowed

@Runmc, Unknown_road --> Can I add you guys to members list ?

We can create two groups, first with only CO2 as II stage refrigerant, and second with free gas as stage II (but without r1150), but I don`t think so that it will be needed.

how about same as last competition
2 divisions
Limited (second stage refrigerant c02)
and then for the big boys open division.
ppl with the $$ can use what ever they feel free.
Since we have to use safety devices there is no reason why we cant use 1150.
1150 boils colder than the rest, but it also is very hard to condense if using it.
ya gonna need a mean auto first stage to get it to condense
Count me in if we can use 1150

Sounds pretty fair, I'm going to need some wicked innovations to compete.
I like the way this sounds.
Maybe the free division though, needs to also be able to hold a load... And measure there temps on a large load..

Good idea, you`re in !

We can create two division like said Kayl, one with only CO2, and second with other gasses, I will modify rules. We all will use safety devices, maybe do something like this, that who ever have been using r1150 or have built cascade he can use r1150 in auto-k, else can use only CO2 ?

[n00b 0f l337]

Okay then I'm CO2 Division for the moment.

If I can get some one to help me (instructions) I'll give it a try.

Common ron, if I'm going to give it a shot you, a veteran phaser, shouldn't need "instructions" :P

[LukeXE]

Okey, runmc, YGPM.

Second, from that momment I will not edit first post, only for write new members, or if one of the judges will tell me to change something.

well i think teamPuss.com autocacade section has some good builds.

Runmc have you still got that HX you made for last comp.


Also we need ice bath shots in this thread of all competitor when updating their lowest temps

[Redwolf]

Rules should be with a loaded temperature. And the same type of dummy load.

[LukeXE]

So, this is my ice bath shot.

I think we should use ~200W dummy load.

[n00b 0f l337]

I'm bidding on a thermometer now and I dont have a dummy loader. Maybe runmc could sell parts off under-the-ice for whats required?

[cold_ice]

You should get the right resistors for a dummy load at every electronic store.

[pythagoras]

In the open division, can we use any compressor? HP rating isnt as important as displacement here.

[pythagoras]

On the judges question, personally I would like to see runmc and chilly1 compete here, I think this competion should enable a truly practical autocascade, at least that is what I would like to see.

How about the participants judge the contest?

Each competitor gets to vote for 3 systems scoring them 1st 3 2nd 2 3rd 1, obviously they cant vote for their own. Highest score wins.

On the subject of load testing, I think 200W is a little much for an autocascade.

I see autocascade's as being ideal GPU coolers, but not really being suitable for maxing a CPU...

so, maybe 120-150W would be more realistic here?

[piotres]

I agree ...200W and higher isn't a load proper for autocascades

[n00b 0f l337]

The problem I see with co2 is some people could just run the setup really quickly in order to not show dice problems.

[runmc]

Runmc have you still got that HX you made for last comp.

Yes I do

Common ron, if I'm going to give it a shot you, a veteran phaser, shouldn't need "instructions" :P

I have never built an autocascade. This is a little bit more advanced.

well i think teamPuss.com autocacade section has some good builds.

http://teampuss.com/forums/viewforum.php?f=46

Yes there is plenty of info there to build an autocascade.

In the open division, can we use any compressor? HP rating isnt as important as displacement here.

If a guy in the open class wants to use a 5hp compressor - WHY NOT?
I mean it's not like we're gonna win a trip to Hawaii or something.

[n00b 0f l337]

Yeah at least you've done a cascade, I'm doing this for fun and using not so dangerous gases and I'll be at my safest. :P Compressor size should stick. Otheriwse someone can do a subcooling LN2 build.

[Fhqwhgads6680]

Hey guys count me in! I think im gonna go for the open division, just because CO2 sounds like a pain in the arse. Current parts:

Matsu 3/4 hp

R402a / ???

Cap in cap for now, I saw it asked but not answered is CNC evap ok or not as long as it is your design?

Also, how would R116 work for second stage? isn't it alittle less dangerous/high pressure than R23? Still doing research on 2nd stage gas so leave undecided.

This is gonna be awesome! Let the games begin!

[LukeXE]

I just have rewritten the rules, and I wrote something like this:

"-R290/R22/R404A/R507/R134A for I stage refrigerant, gas for stage II...use your imagination, we have two groups:

First called "CO2 Division" --> people that ever haven`t used any high pressure gas (or builded earlier an autocascade or cascade), like CO2/R23/R1150 can use ONLY CO2 as II stage gas.

Second "High pressure Division" --> This group can use other gasses than CO2, like R23 or very high pressure r1150 (but they must have experience with that gasses !"

So, we`ll create open division without compressor size limit or "High pressure" division will hasn`t compressor size/power limit ?

[Unknown_road]

I agree ...200W and higher isn't a load proper for autocascades

if the load testing will be done at less then 200watt I'm definitly not going to join. The autocascade should at least work on a high powered cpu.

[n00b 0f l337]

If prizes occur for the competition then, people must compete in the CO2 to win. Open division is just to open... No rules no limits is going to have someone going as far as a 2 stage compressor or something.

Also make sure to say that disqualification's by the judges can happen if a competitor is not competing fairly in the competition. And if someone posts there autocascade before the end date the Judges are allowed to force a change if there breaking the rules or competing unfairly.

[LukeXE]

if the load testing will be done at less then 200watt I'm definitly not going to join. The autocascade should at least work on a high powered cpu.

With high heat load like 200W we will see bigger difference in units construction and handling that kind of load (big load).

[Gray Mole]

Well for one, it's hard enough to make an autocascade work at all, much less at 200w.

For 2 what cpu exactly pulls 200w?

But personally I don't really see a problem with people choosing what they like.

I'd say that in the CO2 division that 150w would be ideal.

For the 'open' division using a 200w tester is fine if you like.

Just seems like that's a fairly high bar to set for everyone, especially when 150w is closer to what 99% of the 'real world' cpu's end up putting out for load.

And if R23 is fine to use for either one of the divisions, I'm happy to switch mine to a 290/23 Auto if that's ok So I'll be in the 'Open' class I suppose.
