Going to Lowes & welding store tommorrow...

[=w=]

Now what all do I need to buy? I already know the MAPP torch, the compressor, I don't think I can get a condensor at Lowes, and I don't need to get the gas gauges because I'm getting the system charged by my moms good friend who a refrigeration guy.

Well anyways, before I drift to far off subject, I just need to know what all I can buy tommorrow so I can get it out of the way. Thanks guys.

My suggestion to you would be to learn the basics of refrigeration before you get started purchasing parts. Find out the basic components and how they work.

Do some research on your own . (Again I suggest reading stickys)

This is a link to "Basic Refrigeration". Read it until you understand it.

You may want to consider purchasing a used Prometeia. If you still decide to build you get hunt up an old refrigerator and make a chiller to start with. There are several options, but first learn the basic.

Ditto.

I can already tell you're not ready for this yet, because you're going to lowes and you dont even know what you need to get.

Çhrist0ph, you're right I don't know anything about refrigeration or phase change. No one is born knowing everything about something or another, thus learning comes in. And I figure to myself, and I've been told, if I don't understand something, don't be afraid to ask someone.

[hrhrhrfoot]

You should read the stickies first, and learn how refrigeration works. No way should anyone be building a direct die if you dont know anything about phase change. Dont buy the parts;learn how it works. I know you are hoping someone will give you a one stop answer and boom you can build a DD system--i did too. Unfortunately, it just doesn't work that way. You have to put time and effort into it; study the stickies day and night. Good luck!

I just saying you NEED to understand what your doing before you start with anything. You need to know exactly what you need, how its gonna work, etc. etc.
If you would just read through the stickies and whatnot, youd be ready to start before you know it. But dont jump into the deep-end of the pool...

Thats just it, I don't know where to start. I've already read Lard Arse's guides countless times, read how to braze block, read the safety when working with refrigeration gasses thread, and others. But in none of these were something that said where to start and to end. And that's all I'm needing. I mean, I already understand the basics I think. I just need to know the next level of stuff and then I'll start.

This thread explains a few things you'll need to have.

Cooler Rebuild

A few things you can get at "RParts", Johnstones Supply, United Refrigeration, Grainger, Borosco. These are a few supply stores that I know are in Texas. They all have online stores except Borosco.

Look at the pictures, study and learn the parts, and learn the basic refrigeration cycle.

Learning Basic refrigeration is a must.

Like I told you in the PM, you could find a window a/c unit or and old freezer or refrigerator and use the parts out of them.

I also wanted to ask a few questions and learn how to build DD over night,but it doesn't work like that. I have been at it for over a year and I still understand very little, very little.

Thanks runmc, chilly1 suggested a 5,000btu Goldstar a/c unit that goes for about $80. So, I'm going to follow his advice and get that.

Lardarse's guides are top notch, they are extremely helpful and informative. I only had to print them out and read them a few times while i was on the crapper before i was ready to go. But not only read the stickies, but search and read through thev threads in this section. If there is something that isn't quite clear, just type it in the search bar and see what comes up.

Alright will do! But as of now, I'm on www.phase-change.com reading all of bowmans how-to guides and his "basics of phase change" stuff. All VERY helpful.

Great idea!!! That's where I started out learning about chillers. A liquid chiller was my first phase change project.

[=w=]

How does a liquid chiller work? Is it just eXtreme water cooling?

Like, do you still use water blocks, or does it require an evap?

[trueplaya4ever8]

pretty much extreme water cooling, still use waterblocks, and it requires an evap to be put into the "water" mixture, which is of course in the resivoir, like a cooler. check out the chilled water cooling section.

(correct me if i am wrong on anything )

i was recomended to do a water chiller but i dont want to buy every needed for water cooling. trying to see what i can mooch tool wise from ppl i kno , and i should be geting started soon.

Think of it as a WC system, with the phase change system taking the place of the radiator.

[masterofpuppets]

Yea, like the condensor is the radiator, the compressor as the pump (i think) and the evaporator as the block.

Um, Im sure that a chiller requires a standard water pump to pump the chilled water to and from a waterblock in a seperate loop. The phase change side of it is to chill the water, as Gary said like a radiator.

Seriously =w=, a little reading is required. You can't expect these guys to answer every question you pose which has already been answered elsewhere ( Stickies or using the Search).

[=w=]

Oh I know, I'm learning alot as I go, just asking the questions I need to.

[hrhrhrfoot]

basically, the air conditioner has the evaporator already cooling down to nice chilly temps. People just put the evap in a res filled with a liquid mixture, and they usually go down to about -40c at best IIRC.
