Although I don't understand half of it, I can appriciate the hard work gone into the build.
The brazing quality, craftsmanship, attention to detail, and planning are incredible

Ya ,it's a shame you just can't lacquer the shinny stuff....most all needs to be covered by insulation.Originally Posted by sacha35
Hey you could color code & label the piping & insulation. They have tape thats color coded with arrows indicting direction of flow.Then label the major components. I sure you will be answering a lot of questions where your cascade shows up,labeling will help people understand direction of flow & whats things are.....
But you probably already thought of that........
Forum members, if you really look @ this cascade about the only "EXTRA" parts are a few fancy quick disconnects for the electrics. And those are necessary for the purpose,portibility and ease of repair.All the rest is necessary.
It "shows" so well because of all the planning & attention to detail BAXZ and SACHA35 did. It usually doesn't cost much more in material to do a professional job ,just a little more labor. This is offset as you acquire the tools, not having to hire out work and you get faster & better with experience. Plus, professional work brings a premium price but more important "more work".
Example : You need the same compressors,same tubing,HX's, Starting & safety components, wiring in every similar unit. You can do neat professional workor you can throw the stuff together to look like crap
.
Many customers hire you because they don't understand or do not have the ability/tools to do the work(applies to any job). So they judge your work on neatness and of course it has to function as intended............. < Thats the formula I found to build a successful business on and have customers/friends for life. It doesn't matter if doing HVAC/R/E or mowing lawns...neatness counts,and you bet your customers notice....
Keep up the great work.......

thats real nice thing to say there walt thanks mate
Made some head way today 2nd stage is now under 20 bar test pressure
i will have to get creative with the R23 receiver as i did not allow for the insulation of this part and the cold will spread out from its mount to the aluminum base plate but i have a few ideas on how to deal with it
the safety blow off valve for the R23 has been mounted in the lower section as i needed to be able to get to this part for maintenance as they sometimes don’t hold up and need to be replaced and I have some room there

1. The first rule of Bench Club is, you do not talk about Bench Club

7. Benching will go on as long as they have to
8. If this is your first night at Bench Club, you have to Bench
my R23 receiver is mounted on an acryl bottom with insulation between base of unit and acryl. it works
Good insulation on receiver of lower stages is very important.
Very nice, very clean
I am following your project and like your work mate!
thanks godmod

Again looking great, how much was that R23 TXV, and what tonnage it rated for? I'd imagine you don't need more then 1/4 ton of capacity.
If you have a cooling question or concern feel free to contact me.
No sight glass used before TXV?

You can just charge by sub-cooling. You don't need to SEE the liquid to know it's present.No sight glass used before TXV?

Great work like always Bazx. You never stop to amaze me
Beautiful work man.
Well, I hope I didn't got it wrong. The capacity rating of the valve depends on the orifice used:

I know that there are no data for R23, but maybe someone here could calculate it. I think I can, but I don't have time now since I have classes tomorrow and its 01:00 in the morning :/

Excellent work Bazx!
One Servant: it seems the working fluid is flowing in the wrong direction in that 3 stage compressor in your sig ???

Do you wanna Play Thermodynamics ????????
No, think about it. Depends whether it is a compressor or a generator.
AFAIK the animated pic is from Wikipedia.
looks like a generator to me.
Bazx..... this thing is awesome. so neat aswell. kudos to you and w00t for the UK, you make me proud to be british.

I relized that, but why a picture of a generator in your sig in a PC OC'ing /cooling forum??? Reverse the flow and it illustrates a 3 stage compressor.
My brain works in weird ways, just thought it wasn't noticed it wasn't a compressor.........Back on topic............

Yup, you guys are right. I added that to my sig because I thought it was an excellent thermodynamic display...most fitting for the games we play here. Anyway, I'd thought about modifying the animation for a more accurate representation but when I broke the GIF down and realized how many frames it was composed of...I decided against it.
Man, I just love you engineers! Forgive me for I'm a lowly psychologist. Did you know that 95% of all engineers' personalities fall into the same category when tested with one of the most common instruments (the KTS-II)!? Wdrzal, I would bet money that you’re a INTP…

Hehe, I understand
I saw it before on Wikipedia and thought about it, so thw pic was familiar
edit: nice one_servant, ill read that
Been a busy boy today
i now have all 3 stages under 20 bar test pressure and will leave it like that until Wednesday and then will begin vac down and fill
i also have the evap mount complete which leaves the brazing on toms V8-R evaporator
the last job before load testing
here is some info on how I painted the pipe work
1. Bend fit the pipe work for the stage I am working on
2. Take out the pipes that need to end up painted
3. Paint them using a spray can but leave the ends still copper for brazing
4. Reassemble and braze in using a damp cloth around the pipe being brazed to absorb the heat
5. Mask off the rest of the parts you don’t want painted
6. paint

wow bazx, what a clean work! i am really impressed!
i hope you have pressuretest the unit before painting, i've got to work with some units that someone had painted the piping on which where leaking.. not fun at all.
cheers.
Tim
Looking great still. Was justl ooking through thread again, why do you have another smaller condenser/desuperheater/coil down below with the big one?
If you have a cooling question or concern feel free to contact me.
