My first phase change project

[GoThr3k]

hi,

i am having some issues with my first phase change project, first of all i dont know wich gas i want to use, and wich is best
i heard some things about r22/23/134a/404?/507?
my aim is -30 on load, if that is possible
its a single fase cascade(?) not an autocascade or dualcascade
i know where to get all the parts so that not the problem, i am working together with a coolingtechnician :banana: so prolly everything will be ok, no explosions or so :p:
another problem is the kind of insulation i want to use, i thought about neopreen??
but arent there cheaper or better solutions :confused:

thanks in advance,
GoThr3k
Edit// what should be the diameter of the capulary tubes??

Welcome to Xtreme, read the stickes and use the search button. Read read read.

[GoThr3k]

thx
i've been reading a lot of things the last days, i just read some of the guides of lardarse
but i really dont know wich gas i have to use to have some proper results

[crotale]

Many people use R507, R404, R402 for ~ -40C load

[GoThr3k]

thx crotale
and what about r22, is that a good one, i thought i was very cheap and that it cooled good
is this true
edit// r22 looks good in combo with r290 , anyone that has experiences with this combo
and it will be prolly 1/3 hp compressors (or is 1/2 recquired?? , for what i have read 1/3 is ok) from scrap, and the price wil be likely around 150 euro for the entire unit

[GoThr3k]

what about r402, does that cool wel, i ve seen some of fuggers things
and it does pretty well, will it work good with a 1/3 or 1/2 hp compressor??

The gas will depend of the oil in you compressor :
example
Mineral oil you can use R22, R290, R502, etc
POE oil for R134a, R404A, R507

i knew that already but still thanks for the info
but isnt it true that r22 works also with poe oil
edit// just found out that r22 is illegal in my country :woot:

[GoThr3k]

does anyone know how to make evaps???
what of wattage should the compresser be able to handle ??

[n00b 0f l337]

A ton of people know how to make evaps and will sell them to you. But it can be pricey. I suggest finding a drill press and get some copper and make your own.

[gclg2000]

@Got POE will work with any gas.

And about the evaps...your are buying more than the block itself when you purchase a chilly1 block...you get the mount down system, all the research he put into it, and after all...all the knowledge you get from this site although it will always be free and we will always help you...buying a block from him does help support this FREE forum

However, making a evap can be alot of fun and give you alot of self assurance when making a nice one and doing it right. I've made a couple custom waterblocks and one custom evap,...since then, i've recieved going on my 4th chilly block now.

[gclg2000]

One more thing, this is a great board and if you are on a limited budget, then by all means make one.

Not trying to guilt you into anything. We will always be glad to help, and many other's way more experienced than I will help you out for sure.

Hey Gothr3k!

Weer een belge bij de hoop :) Ikzelf ben trouwens van Boom :) niet zo ver van elkaar, we ligge beide tegen de rupel :).

/sorry for the dutch,just saying hi and all to Got :)

Ok,first off, I believe Fugger is the LAs Vegas dude and Chilly is from denmark so shipping isn't international (no water to cross) so I think it will be cheaper to get a chilly block then if he lived in the USA :)

Second, If you do finish your Phase Change/ single stage, let me know. I am considering either buying me a Chilly1 in a few months or building my own, but if you have a coolingtechnician you work with, maybe if it works out well you'll be willing to build another one for me also? ;)

BTW, YGPM

[Tyrou]

fugger and chilly are from las vegas, pcice and opp are from south california, so the shipping will be overseas :(

[Entity_Razer]

dam. who was the guy from denmark or something then?

edit: BTW GOt, Xchangerates are your frend ;)

I once calculated that a 500$ chilly unit + 100$ schipping (a guess) would cost me 470 euros (about that number)

So exchange rates are your frend ;)

[Tyrou]

tom holck is from denmark

macci/sampsa/kamu/the stilt are from finland

ha, kvoel mij hier al direct thuis ze :banana:
goh mijn ding gaat zo max 150 kosten ofzo, kben van plan er een stuk of 6 te maken , 2 voor mij 4 voor andere

sorry for the dutch
i work with a cooltechnician, a guy who is a teacher and works on his own
teh materials arent the problem, only the evap is causing some issues right now

[GoThr3k]

some things i need your guys help for, what about the length of the cap tubes
i honestly dont know wich length that is good to go with r507 or r404

[Entity_Razer]

well I don't know that also, but got, if your one costs 150 euros, does -30 and can be fitted with a chilly evap(i'll buy it, have it deliverd to you) I'm in my frend :)
but we'll see when your one is done (I want pics ;) )

how can it fit a chilly evap :confused:

[Sneil]

maybe you should get your gas first then worry about cap tube length. Also start out with a longer cap line and experiment by shortening it until your temps don't get any higher. Takes some time but its worth it to get your max temp and you'll also learn something for your next system
:eh: a chilly evap will fit any system...

[GoThr3k]

does a longer cap line affects you temps???
a shorter one does, i get that poit, but longer cap??

[Sneil]

yes the cap length effects temps. the longer it is the less refrigerant it will release, the shorter the more. Longer = more resistance. it all depends on the heat load.if you hav a smaller load, say a gpu then you'd need a longer cap tube as you need less refrigerant then you would for the cpu (higher load) .Using a cpu length cap tube for the gpu would release too much refrigerant and wont evaporate all the liquid causeing it to overflow. I said start out longer so he can shorten it after testing to optimise for the lowest temp possible. better too long then too short and having to add cap tube in incraments wich would be just dumb... :hitself:

[GoThr3k]

and what will happens when i place a pelt on it, -70 orso??
what wattage should the peltier have???

sorry for all the noobish questions
but can anyone answer this :stick:

[smurfmods]

A pelt on a phase change evap? I don't think a pelt would help any. It may make things worse. Pelts may have a limit to how cold they will get.

[Jort]

don't use pelts, its not worthed.

just make your single stage and it will do ;)
