Step by step guide anywhere?

[ny_driver]

I need to know where to start and what I need to get.....I have an 5-6000 BTU A/C and a 5 cu.ft. freezer at my disposal.

I want to build a single stage cascade or maybe a 2 stage, not really sure.

I know I need to do some more reading/research, but I'd really like to be looking in the right place instead of just reading random stuff I can find on the subject.

Thanks Xtreme Mates.

EDIT: I see the Phase Change Cooling Guide, but no step by step guide within, and half the links are dead.

start with a single stage and make your first experience.

reading in this and other forums is the best advice you can get.
because you can read about problems and how they could be solved. this helps you for a better understanding of what you are doing.

following a step by step guide isn´t a good idea for a beginner. because you don´t know what you do. so read here and understand what is important for such a cooling system. then start with your own.

I will understand better soon, but I need to know what parts I will NEED to buy. I have the tools and the brazing skills to build the system.

EDIT: I think I'll just build a sweet water chiller for now.

Here you have a basic (and old) guide to phase change, written by one of the guys here:

the parts you need to buy depends on what you want.

for a chiller you need a compressor, filter drier and a condenser
than you need an expansion valve that could be a capillary tube or an thermostatic expansion valve. if you are using a thermostatic expansion valve you need a receiver and a sightglas and also a high pressure cut off switch.

the evaporator can be a large copper tube or a plate heat exchanger.

then you have two shrader valve one in the high pressure side and one in the low pressure side for your manifold to messure the pressure.

i prefere the solution with thermostatic expansion valve and plate hx:

Is that a chiller there? Whatever it is looks awesome. Thanks for the way over my head atm explanation. EDIT: and btw you were right to start with, thanks for the advice and all the great pictures to look at.

Thanks for the replies guys.

I just want to build your standard a/c modded into a chiller for now I think until I begin to understand better. I've found some threads outlining building one. But I'm sure I'll have many questions, so I'll start a build log probably.
