Chiller inquiry.. :)

[erwinz]

I decided to opt for a chiller..

my 1st plan is water cooling but in my house normally.. ambient temps are 35C to 40C maybe lower at night.. but not feasible for a good water cooling setup.. definitely no air cooling can help..

phase change is out of the question.. :D more expensive and more power hungry..

please help me in my 1st water cooling.. ;)

[erwinz]

1st off a chiller can handle quadcore's??

just a question.. :) maybe future upgrade..

[erwinz]

can this pump suffice..

this will be my water block..

and also I want to cool my chiset..

http://www.swiftnets.com/assets/images/products/mcw30/MCW30.gif

can this blocks hold the temp??

[erwinz]

I'll be using 1/2 barbs..

the design of the chiller will be post later.. :)

please i nee your inputs guys.. thanks.. :D

Very nice, how do you plan to cool the liquid? Are you going to use freezer components?

[erwinz]

yup going to use freezer components.. my buddy here will modify me one.. but I don't know if my parts can suffice the temperature..

[erwinz]

anyone?? comments please.. :D

Phase chiller will easily handle entire Skyscrapers if built well and to size. With that said we obviously need some thing much smaller, say in the 3,000BTU/h to 6,000BTU/h range (This should allow for much expandability for future add ons)

Now with such a high condensing temp you will want a condenser capable of rejecting up to 8,000BTU/h this will greatly prolong the life of the unit and help keep power usage to a minimum.

It sounds like you want economy here, So yes the MCP655 will work nicely and reliably down to 0C, how ever we shall assume 7C water return temp.

Variable that now need to be filled is refrigerant
R-22 is naturally the defacto gas used in A/Cs and such, but I'd care fully consider the use of R-290 due to benefits offered. R-22 how ever is nearing end of life phase.
R-290 is a very nice gas that works exceptionally well (Build the box, so it is all ways ventilated by convection or such, drop in compatible with R-22 equipment.

R-134a is another excellent gas for chillers, you can use R-12 TXV(TEV) with it with capacities being pretty close. You must change the oil in the compressor is using R-134a in a R-12 compressor to POE from Mineral.

There is some more to add but my mind just went blank, so I'll add it later when it comes back to me.

FYI chillers are phase change just implemented in a different way.

[Xeon th MG Pony]

They have their unique design challenges in them self as compared to more simplistic Single stage, direct die systems.

Albeit they both operate on the Carnot cycle, they are not the same thing on fundimental ways as there is a whole new layer of designing one must do.

Phase change has become to mean simply a SS/DD (Single stage/DirectDie)

A chiller is almost the same as DD phase as it requires a refrigeration compressor,condenser and evaporator.

You are sure not going to get any more than a few degrees below ambient(evaporative cooling) unless you use a small compressor.

here is the update on my hybrid chiller project.. :)

"1/2" Barbs & Custom T-Line

Though not directly a part of the chiller system, the custom T-Line will be used as a part of the liquid cooling system for which this chiller is being built. The 1/2" barbs will be brazed onto the hybrid heat exchanger of the chiller system to accommodate the 1/2" tube size of the H2O kit." -Jercouzen

here are the pics.. :)

That is a lovely condencer! where did you score that from?

[erwinz]

hehehe custom made from the Philippines.. ^_^

[Starkiller42]

Dude, tell whomever made that to start marketing those here! I'm serious!

It makes me laugh that you don't have much put together, but you have the one part I don't ;). Continued good luck to you.

[erwinz]

hehehe.. my parts are coming this week from the machinery.. :) just wait and see. :) hehehe

FYI chillers are phase change just implemented in a different way.
Phase Change is "Change of State" of the refrigerant and we just call it "Refrigeration".

[Jercouzen]

hello erwin.. finally got validated today.. :D

i'll be bringing you-know-what today so you can see it.. hehe :D

[erwinz]

hello erwin.. finally got validated today.. :D

i'll be bringing you-know-what today so you can see it.. hehe :D

Welcome to XS dude.. :)

very nice bro.. let show them what our design is.. :D will wait for you later.. hope you can get it today..

[Jercouzen]

thanks man.. :D

i'll be there around the same time as last time :D

[Jercouzen]

seeing as erwin isn't on tonight, i'll update this thread for him :P

erwin had a special request when he asked me to design his chiller.. can anybody guess what we'll do with this? :D

Obviously I and everyone here knows that.

But we call DD phase change, phase change for short.

hey bro.. very nice..

I'm really excited this coming Saturday.. :) hehehe.. bench bench bench.. :D

:woot:

[Xeon th MG Pony]

Why have you split the condencer? Does the compressor you will be using have an oil cooler, or are you going to do a 2 stage DX system and need an inter cooler?

If the 2 stage is the idea you can use liquid injection in a interstage HX instead of using air, and thus you need a smaller IHX, by using 1/10 of the systems total capacity to calculate your injection cap.

[Jercouzen]

@ erwin

lol let's just hope i still have enough money left for gas and silver after i buy the compressor :P

@ Xeon

hehe, it's not going to be used as an interstage.. we'll post the results this saturday.. :D

[Yukon Trooper]

Why not try out one of Coolit TEC coolers? They can compete with all but the very best water setups.

[Jercouzen]

hehe we've already seen what the CoolIT can do.. not impressive at all :)

with our Philippine ambient temps of 35°C midday, that TEC cooler is extremely gimped, as the TEC's performance is limited by how much heat its blower can dissipate from the TEC hot side into the air :)

also, this chiller i'm building for erwin will cost only around Php12k, or $250 US, to make.. :D considering that a CoolIT TEC cooler sells for around Php11k ($ 234 US) here, you can easily see why erwin would go with a chiller :D

[Starkiller42]

Coolit for the loss!

[Xeon th MG Pony]

lol. Pelts suck, and not in a good X rated way.

[Starkiller42]

I admit, they have their uses. They can be quite useful in a few applications. Just not computer cooling :D.

[Xeon th MG Pony]

Exactly, car minifridges with a 130 watt pelt are great.

[erwinz]

Why not try out one of Coolit TEC coolers? They can compete with all but the very best water setups.

hehehe.. not a chance.. :) I have try TEC.. and I think they have loss its effectivity..

maybe some manufacturer try to make TEC application for North bridge cooling heheheh
