But I have a question then, if you put in a bigger condenser, would it cool the whole system down even more?

Very nice guides

I'm kinda starting to understand how these phase change cooling systems work. If I were to make one myself, how much would it cost me in total on average (excluding the tools)?

Depends, do you accept using used parts? If you do, then i would suggest making a visit to your nearest refrigeration-tech/shop whatever and ask them if they have something lying around

. This way you can make nice finds and if you are very lucky you just need to buy a new filter and maybe some capillary-tube. If you are looking for new parts i'm sure someone from NL will answer you

good work LardArse, i will need this guides

Hi

I've been using these a lot to learn about refrigerents:

http://www.heatcraft.com/resources/refrigtable.asp

and finally this great program:

Perhaps some of you could use them too..

**LardArse** · 01-03-2005, 10:28 PM

Great links my man! Thx for the informative addition!
That proggie looks like its very useful... but dauntingly complex at first glance

It IS quite complex.. there is a lot of functions that i still don't use.. and also an add on module which i guess can emulate systems.. but haven't played with it yet..

Great info on there

.
There any guide to a home made simple direct die block ?

Here's how I do up simple but great working evaps:

Been on cap evaps ever since my first

**Marvin** · 01-09-2005, 10:22 AM

thanks shamino, that is a simple evaporator and would fit perfectly on my almost finish phase change :

No prob, lookin very nice there.

Man, this is super guides...I don't know what could be if i didn't read them.
Thank you very much

) There should be more such good people as you.

**LardArse** · 01-13-2005, 01:56 AM

Wow thanks, thats a great compliment. Glad you enjoyed them!

**Him** · 06-07-2005, 08:34 AM

Sorry to bump this thread, but I gotta. I am very new at DIY Phase Change, and am about to very soon start my building of a basic DIY Phase change system. When I first decided that i was going to undertake this venture, I went onlinbe and learned all I could about refrigeration basic. THAN I went to learn about phase changing, and then to evaporators, etc... I have to say that those guides are great. Especially in the order they are in. A n00b at this sort of thing should learn about those subjects in that order. Excellent, I am going to read all of those and learn even more!

Cant wait to start on my project.
Thanks!

**[XC] gomeler** · 06-07-2005, 12:52 PM

I agree =) I've got most of the pieces together to make my first run at this, just need to find the correct gauges so I can do this safely. Maybe by this weekend I'll have a rough product for pressure testing.
Great Guides, shows all the tools needed.

**zub** · 07-04-2005, 07:09 AM

waaahaay!!! i can finally post!

well...i am a complete n00b at all this phase change stuff but i wanted to build one. After coming to this forum i almost completely gave up hope on building one of these systems as it looked sooooo complicated but after reading your guides Lardass (lol) there is still a little hope hope for me

i think when too many "T"s came into the guide you kinda lost me a bit

one main question i have is about the evaporator, because i always thaught there would be two pipes/hoses connected to it, one for getting the refridgerant in and one for evaporating it back out into the system, but from your guide pictures i got a little confused as i only saw one hose

and all those "T"s did not help

anyway i'll read up more i guess, one more think i'm going on holiday tommorow down the far east, any suggestions on things i could pick up for cheap, i know i may run accross a condenser because the use AC's alot (very hot)

Any way, piece out dudes!

**marvt74** · 07-04-2005, 07:53 AM

Great guides there, i'm slowly reading up and learning but the cost of tools is a little daunting before i even begin to look at costs of materials

**Jort** · 07-04-2005, 08:52 AM

the single hose you see has a cappilair into it(metering device)
its through that the refridgerant enters the evap

most guys run the capillary tube inside the suction line, thats why it appears to only have one line to the evap.

this makes a cleaner looking job but also has the benifit of lowering the temp of the refrigerant in the cap tube which increases capacity.

ps: lardarse evap design is cheap to make and a very good design,

**zub** · 07-04-2005, 11:50 AM

oh i see......finally i'm beginning to understand more.

luckily the place where i'm staying at for my holiday (our holiday home) we are currently thinking of removing our AC as where selling the house, so i'll make sure i bring some parts back from the AC. the compresser, condenser and probably the filter.

ps - in that guide, is that a self made filter??? how do you make one? is it just a capillary tube turning into a larger pipe and then a cappillary tube?

but that seems a little too simple

and also where in the world do you get solid copper blocks for the evap? i live in UK London so scrap yards are extremely rare believe me so maybe getting the parts from my old AC will probably be my only chance of grabbing the equipment i need to set up my phase cooler (just hope they dont throw it out befroe i get there!)

**expansionvalve** · 07-05-2005, 06:01 AM

not bad reading at all

**LorD_Kvadd** · 07-05-2005, 06:40 AM

I've just got a prometeia mach 2 cooling unit and didn't know how to properly insulate the cpu and motherboard. Thanks to you now I know

Super guides! Thanks

hey there, I do not know what you mean? if you mean the blue drier/filter, since its 1/4" to 1/4" I need to attach the cap tube to it somehow so i just crimped a 1/4" aginst a cap tube and braze up!

Ummm, I think a whole-house central A/C unit may be just a little too large for our applications
