3 stager build, part two.

[LukeXE]

First, I wanna ask mods to not delete/move that thread to "builder/customers relation forum", because it`s big project, making at all from 0, and any advices from other builders would be appreciated (in builder/customer forum nobody can`t write).

Ok, so I`m working on german 3 stage cascade. Originally project was done with some problems, for some months decompleted and I started it from beggining.

http://img227.imageshack.us/img227/5706/3stageschemees1.th.jpg (http://img227.imageshack.us/my.php?image=3stageschemees1.jpg)http://img227.imageshack.us/images/thpix.gif (http://g.imageshack.us/thpix.php)

Here is the scheme (autocascading stage isn`t 100% true, because in real there is more hx). At this momment I can get it -85*C idle (not vacuum, about 0,1bar @ suction).

Compressor on #1 stage is Toshiba 3/4HP. I used captubes, exacly:

190cm of 0,8mm captube for R290
225cm of 0,8mm captube for R23 or CO2 or R170, depends on what I will have
240cm of 0,8mm captube for R1150.

Phase separators from MAPP gas bottles, for me the best.

Whole HX structure has now new, big, insulation box, but inside you can see that:

http://www.teampuss.com/lukexe/YotoCascade/PICT0189.jpg

I used that autocascade from other customer build, which I had left in my workspace. It`s very strong and has good design, so why not use it.

Compressors on II and III stage will be around 3/4HP and 1HP. Rotary. I`ll use captubes, oil separators made by myself.

I stage is R290/R744/R1150 mixture, second will be pure R1150, third R14 with some methane and argon.

Everything is on very small, steel plate with wheels. Unit will have two dual cut-off switches, manometers.

If I`ll get photos, I`ll put them here as fast possible.

For now that`s all. Will show fast progress :up:

Luke how is it you get your hands on plate HXs and compressors but not the proper copper fittings? You need to work more on your fabricating, you do great technical work but now you need to move on to stream lining the fabrication side of things. This will improve your assembly speed and accuracy and ensure no leaks on the first go.

[HawaiianSupermn]

So how cold will this beast be? :D

[LukeXE]

yeap, I know that I have problem with that.

But at all my "piping" skills will be improved in II and III stage, I works and I don`t wanna "unassemble" it. That work has more than 2 years and it`s leak free, so I`m happy with that.


So how cold will this beast be? :D

Would be nice to see -120-125*C loaded :). Who cares about idle ? It looks cool and girls are screaming when see -150C lol.

[august123]

it seems like the compressors are much too small for an proper load >200W like new cpus on third stage.
but i look forward to see your captube results with R-14!

[LukeXE]

If need, there shouldn`t be problem with changing compressors for bigger ones.

[MaSell]

What is the point in building this unit? Novadays cpus are much "higher" coldbugged than C2Ds. I heared about -60'c/-70'c ones!

[LukeXE]

always is possibility to insulate evap-cpu space with something, to increase cpu temperature. Order was for 3 stager and 3 stager will be done. Who know what future will bring.

It's bad solution, I was fighting against CB for a veeery long time and checked that "trick" very well. In idle temp will be pretty low, but in load - too hot. Belive me

Near future will bring coldbugs, look at all cpus from last 5 years and draw conclusions.

[LukeXE]

So what do you suggest ?

Maybe some kind of valve with hot gas supplying evap. Let`s say, something like cpev, but by using captube and valve to control evap temperature,

[MaSell]

I'm not builder, so I can only suggest to build -80'C 350W unit :) but...

... if customer want to play with nehalem plus this 3stager ;)

[[XC] gomeler]

Just build in a hot-gas bypass to counter the cold-bug and cold-boot issues. Nehalem seems to work around -115C to -95C on average from what I've read around here. Of course there are always chips that'll run much warmer, I used a QX9650 that coldbugged at -88C :shrugs: Have you tested that 1st stage for how much of a load it can handle? Would be a shame if it crashed when the 2nd stage was loaded by the 3rd stage. Do you stuff those MAPP cylinders or just depend on their sheer volume and velocity reduction?

And yours did better than mine as I recall I couldn't even boot at colder than -68c....

[LukeXE]

months ago I tested that I stage and without big calibration it holds -50 @ 400W load (If I remember correctly)

Impressive! Curious though, wouldn't it have been easier to do an R600/R170, R600/R23 or R600/R290/R744 autocascade and avoid that R1150 loop or are you simply adapting that "autocascade" as the first stage? If I were aiming at just condensing R1150 in the 2nd stage I'd say R600/R170 or R600/R23 would work like a charm.


And yours did better than mine as I recall I couldn't even boot at colder than -68c....

well that was gautam's chip that I was describing above. All my chips have had CB around -110C to -120C and CBB around -95 to -105C

Second option. I just got that "stage" done and wanna adapte it to that project. If it won`t work, I`ll make normal I stage.

About MAPP bottles. They just work excellent, separation of refrigerants is very good. don`t know why and I don`t care :)

I learned that lesson myself the hard way....

[Circaflex]

how exactly does this thing work...it looks like your using parts from an air conditioner...i remodel houses and scrap AC,s for cash daily...i must know more..its a phase change cpu cooler right?...ware on the internet can i learn how to build one...i have torches..pipe cutters the whole 9 yards...i want to build one....some one pm me if thy have some info..:D

somewhat outdated, you need certain certifications tho too. I was also told by a builder to buy this book:
first off buy this book at amazon.com
"modern refrigeration and air conditioning"

Pick up the epa 608 universal test, its a huge book you need to study then take an exam for.

I'll say +1 on both having the tendency to be tought the hard way as feeling Luke's being talked into the ground. Maybe it was just a couple of hundred buck but since I was so :nuts: to be my first iban transfer twice ( as it didn't get removed instantly but at midnight, I thought I'd done something wrong ) and so he got twice the money I was supposed to send. He gave that back, it's was my mistake so I did loose on currency exchange but he could have said tough luck if he was the kind of guy you're making him out to be? Maybe he deserves some credit for having fixed almost all his issues and now trying to resolve the one's that remain?

[Circaflex]

im pretty sure you need to be ceritified no matter where you live, and its frowned upon here if you do otherwise fyi

excellent build luke, this thing is going to rock. cant wait to see more updated pics and i like your idea with the mapp gas bottles.

void, you obviously are looking past every precaution posted on these forums. just because you do remodel work every day dosent mean you can put together one of these thing and still have all 5 senses and all extremities left after your done. especially any form of cascade. if you want info i suggest starting at the top at the stickies. i also reccomend reading the ones about safety first especially in your case.

yea well if some one is dumb enough to run around doing ac work with out there 608 then thats there problem...you would s:banana::banana:t you hippie pants if you knew all the people i know that just cut the line,s on scrap AC,s and just let em leak 10 at a time to cash in at the scrap yard...but hey people gota feed there kids and thats just a sign of the times.:up:.most people with money arent effected...while the poor are climbing in higher numbers every day so frown upon who ever you want to just dont forget to snut you chin..:up:

Keep in mind that if he doesn't live in the United States, then EPA has got absolutely no relevance whatsoever.

Anyway, my understanding is that you don't need any kind of permit to simply build a refrigeration system - after all, you're basically just brazing copper tubes together - but it's your acquisition and use of refrigerant gases that falls under EPA legislation. I could be wrong - feel free to politely correct me if I'm wrong.

If you have a cylinder of propane, or methane, ethylene, carbon dioxide or whatever, then you can do whatever you please with it, since it's not a chlorofluorocarbon or a hydrochlorofluorocarbon, and as such, it doesn't fall under EPA's restrictions as a potentially environmentally harmful refrigerant.

[teyber]

what illegal practice...building a water chiller from an air conditioner...its completely legal and doesnt involve releasing freon and for every one of my posts theres 2 counter posts from you guys telling me im a bad person and im going to prison and that i better get a license that i dont actually need for what im doing..and on top of that some of you are attacking some of my posts in other threads for the h#ll of it so i could bring those posts into question for any moderator to look since you guys are crying spam cuz you dont like a comment i made..and are taking it personal

Guys, he is talking about converting an ac into a chiller by submerging the heat exchanger and that way he's right he isn't going to leak gasses if he doesn't cut any pipes or treis to bend something into a shape which isn't going to bend that way :)

Sorry VOID_WARRANTY the confusion came from you mentioning pipe cutters in one of your posts, that made me think you where going to cut an unit up for parts and then assemble it. If you don't spring a leak, you're not breaking the law I seen to many threads here about chillers made this way by people without a license to say it's not legal or not advised. Only think I want to say is be carefull :up: The Netherlands is abit below sea level already, I wouldn't want you to contribute to that rising even the slightest bit higher :rofl:

Luke, any ETA on when we'll be able to see stage 2 built? If I understand it correctly, the 2nd stage should be a pure R1150 loop. Looking forward to some -90C to -95C shots on the 2nd stage :up:

Yeap, you undestand me correctly. 2nd stage SHOULD be R1150, pure but...

I think if I could make 1st stage running at -75*C loaded...THEN...

...I could fill 2nd stage with R14 (or with mix with that gass).

then 3st I could fill with methane blend. It should give to me super low temperature on evap. At all 2st with R14 could reach a bit higher discharge pressure than usual, with only -75 @ 1st stage.

But it`s hard thing to do. Everything depend on 1st capacity. It`s complicated, R1150/R744/R290/R507 blend is very hard, for me, to calibrate. I`m fighting with that but...1st design has potential, so I got good feelings.

ETA for 2st running should be in this week. Have to think what I`m expecting from 2nd stage as builder. I think I have to make it running with R14, so I would need to redesign compressor --> oil separator line (R14 flushes oil from oil separator, nobody wants oil in evap at -130C). I could use ZEROL oil or sth, but I`m not sure if I can get it here.

Tomorrow I have talk about job in HVAC job, probably I`ll get that job so I`ll have everything what I need from tools and gases, so I can make more profesionall job.

A lot to think. Have to talk with symphy what he expects from that unit. Things changed a bit, new processors, CB etc. I`m ot sure what he wants right now.

[[XC] gomeler]

Well it sounds like this thing will potentially be a beast, my only concern would be it being too cold :D The 1st stage blend in my opinion is too complicated, I'd suggest trying R600/R290/R1150 and cutting out the R744 and R507 if you are still working on that stage. R744 blows as a refrigerant and there's almost no purpose in using R507 when using R290. Just my two cents, take them for what they are worth :shrug: Looking forward to seeing you complete this thing though!

[ryba]

Ok, I understand your point.

I will have digicam in couple of days, depends on postal (tomorrow it will be send). So then I`ll make clear pictures.

I`m building this unit, not from old parts, I`m doing it from parts bought to your unit for your money. Everything, compressors, condensers, evap, heat exchangers, two way cut-off switches etc. I never spent your money for anything else.

I`m going now to shop for some electric stuff to get the electric done (fuses etc) and I`ll borrow digicam to give you 100% proof that it`s your unit and it will be done as it should be. I`ll make paper with todays date.

From 1st thread (http://www.xtremesystems.org/forums/showthread.php?t=135720)... you wrote/show us photos LG compressors for 1st and 2nd stage.

But now what you using in this cascade?

Compressor on #1 stage is Toshiba 3/4HP. I used captubes, exacly:

190cm of 0,8mm captube for R290
225cm of 0,8mm captube for R23 or CO2 or R170, depends on what I will have

And what we you used in Yoto cascade?

225cm of 0,8mm captube for R23 or CO2 or R170, depends on what I will have
240cm of 0,8mm captube for R1150. - topic (http://www.xtremesystems.org/forums/showthread.php?t=127858).


I know that I'm not your client and I'm happy with that! You are making bull :banana::banana::banana::banana: from trust others ppl. :shrug:

I'm phase change builder too and I have some units on my account. Few notes from me: this project is big mistake from beggining. You never finish this cascade. B'couse how you want finish it, when you don't have R14?

You can lie ppl here and they trust you... I don't know why but they trust everybody.

[LukeXE]

Can you read first post, that I noticed, that I used 1st stage from my another project ? What is wrong with quote`n specs of that stage from build for which it was done ?From the beggining of that topic I`m talking about 1st which I had left. And don`t be so sure about R14



I used that autocascade from other customer build, which I had left in my workspace. It`s very strong and has good design, so why not use it.

So what, those things are from junkjard ? New compressor, new condenser, new heatexchanger. Where is the difference of Toshiba and LG compressor with that same power capacity ?

Where is the difference in evap vs evap, where is difference in plate hx vs plate hx ?? I got tons of that stuff, to all I should stick "bought for ..." ?? and cant use it if it`s not bought originally for that build ?

how did u make the mapp bottles into oil seps?

[[XC] gomeler]

You drill two holes in the side and one in the bottom. The bottom hole is used for the separated oil, the lower hole in the side is used as the inlet, and the higher hole is used for the gaseous outlet. I personally would use the hole for the valve on the top as the gaseous outlet and drill out the valve so you don't have that leaking under pressure and low temperatures.

Please notice guys, that those are phase separators :-)

So bottom hole is used for the oil AND gas in liquid state, top hole is for high pressure has, which isn`t liquid yet, so we can get them separated in simple way. Not 100% of course.

symphy, for what temperature we should aim at this time ? I`m not overclocker and don`t know todays cpu`s, what do you wanna from that unit.

I tried already. That`s the best I can get

[[XC] gomeler]

I'm guessing you blew out the gauge then running a high static. I had that happen once on a gauge, was pressure testing to 350PSI and the low-side gauge was permanently damaged.

[eligray]

Looks great man. So lemme see if i have this straight, the first stage is an triple autoc? Where would the second condensor that you're using as a desuperheater go? Right in next to the other condensor? Sorry, I'm fairly new to phase (but will have firsthand experience starting tomorrow;))

Good luck,
Eli

[LukeXE]

Hello

Yeap, first stage is triple-autocascade (let`s say, pseudo, because now it`s autocascading a bit, should be there -90 at least)

The second condenser will be just after oil separator on third stage (wanna have around 20*C on condenser exit, less load for other stages).

@ [XC] gomeler

Yeap, I got too big static for that gauge :)

[LukeXE]

Gotta arranged final parts place, I resigned two-condensers idea.

Choosed two powerfull compressors for II and III stages. Assembled everything. Gotta buy captube, few meters of 6mm pipe, insulation and oxygen for torch and it will be done.

gotta question about dual captube feed. How I can use it ? It`s idea for big load ?

[[XC] gomeler]

Dual captube works fine if you don't have a wide enough bore single capillary tube. I used two 2.6 meter 0.7mm bore capillary tubes b/c I didn't have any larger capillary tubing. This was with a 7/8hp compressor and a slightly undersized condenser. Held the 2nd stage just fine(3/4hp compressor) but I would have sized it to around 2.8 to 2.9 meters to reduce capacity slightly in my build as the HX could have been colder. Just play with it, start with a longer length than you think you'll need and trim it down as you go.

[LukeXE]

So If I gotta 0,8mm captube, I can easly use it ?

I tought that dual captube is "new trick" in phase :)

[[XC] gomeler]

It's less of a trick and more like a work-around for limited resources. Cheaper to stock one size capillary tubing than three or four which helps when you are a poor university student :D There's a way to calculate the capacity with multiple capillary tubings, don't know where I saw the charts though.

[Moc]

I tought that dual captube is "new trick" in phase :)
Nope, it is definitely not!
It makes it just more complicate. So if you're able to get bigger captubes, better use that.

[symphy]

Updates?. Pics.? Loadtest?.

[LukeXE]

Matter of few days :)

Insulated I and II stage, completed rebuilded II stage + loadtest of it.

I`m paying in this month partial refunds for three persons and I`m out of cash a bit.

[LukeXE]

I bought a lot of stuff from HVAC shop, photos on the evening :) Insulation, pipes and a lot of other stuff.

Bottle of R404a and HX should be on monday.

I got job in that shop, as HVAC technican, will work from 12th Jan :)

UPDATE, as promised earlier.

[tiborrr]

That's a great news you got the job, Luke! We are waiting on the pictures of assembled stages! :up:

[teyber]

zomg thats like $30-40 in fittings!

congrats dude, cool to get a salary doing what you love and are great at :)

[LukeXE]

Thanks guys!

Those fittings are horrible expensive O_o Especially 6mm !! almost 4x more expensive than 12mm !

Another part of photos, acutally unit`s photos, at the evening

[[XC] gomeler]

Small fittings are horribly expensive due to low demand. Here in the US I pay as much for a 1/4" fitting as a 3/4" fitting even though it's 1/3 less copper. Just low demand :(

which is why i just make my own fittings :shrug:

[Moc]

You spend so much money on tools but make your own fittings? Tbh, just with using fitting your pipework will be much better than before.

[[XC] gomeler]

And you spend much less time working. Time is money and I hate fabricating what I can purchase for a nominal cost versus the hours spent bending copper.

[LukeXE]

Gotta nice results :up: After 8h of work today.

Made 90% of I stage. Insulated it, calibrated bla, bla, bla.

Did II stage, waiting for HX so I used evaporator just to see, how II stage works and how I stage handle load...and I`m very excited about results !

-81C @ I stage loaded with II stage. Pretty awesome !

Second stage is showing -113C @ -0,5bar suction // 3bar discharge. I don`t have good thermocuple, so for II stage I used one, which showing around +5C higher temperature @ room temp. So real II stage temperature idle is around -120 with poor vacuum made by small, 1/10hp compressor @ 20-30minutes.

So I need to wait for last parts and I`ll start doing III stage. Hope to see next, awesome temperatures, now I`m aiming for -170C idle with methane/R14

Few photos for everyone.

2009y have to be awesome :)

Do it for yourself;) and for your customer;) not for any other persones:)

[Moc]

What ambient temp do you have in your work place?

[LukeXE]

At night around +12, +13C. At day around +17+18C.

At those days ofcourse.

[Patrickclouds]

can you put a load tester of 250 watt under the evap.
because first and second stage have to handle the load of the 3rd stage plus the load of the cpu

[Moc]

You have a very warm cellar ;) ... hope you don't fool yourself. Think that the unit has to work @ 30°C !
I made the experience that it's quite easy to get nice unloaded numbers with autocascades. But with load it is a complete different story...
So don't be too happy before you get some load on the second stage. No load @ evap and a second stage compressor working at 3bar is nearly no load!

[noobzed]

you can do more clean unit ..
yes it work but the design is porr sorry :/

[LukeXE]

I got heated cellar.

I know that those are nice number and I know how auto-c temps look under load :) But this stage was loaded some time ago and it handle around -65C (then) @ IInd stage loaded with 160W dummy.

Now with tunning maybe it will hold better.

Even with -50C I`ll be happy.

But please wait till I`ll finish everything. then we will comment it`s performance.

[tiborrr]

Who cares how ghetto it looks - all that matters is PERFORMANCE. Keep it up, Luke and good luck load-tuning it! :up:

[Patrickclouds]

lol

if i would buy an unit, i wouldn´t accept such a crappy looking one.

you cannot sell an unit with a demolished condenser or hand bended copper pipes.
i don´t want to know how the hxs are insulatet under the cardboard box. armaflex?

i hope that vacuum will be done by vacuumpump and not a 1/10 hp compressor.

sorry but thats just my opinion wehen you build units for a customer

[LukeXE]

As of the beggining of this project, I talked with Symphy and we wanted one:

PERFORMANCE

How it looks isn`t really important.

In box is armaflex. And insulation works good.

About any tools like vacuum pump or so, cool, I just made test vacuum to check how it will work, to show photos of -11xC temps. (prove that I`m working on that unit). I gotta professional hvac pump from job, so no problem with that.

About any "demolished condenser" etc, cool to, can I first finish that unit and then make it looking better ? And condenser isn`t demolished, I will make those pins looking good, I got tools for that :)

Probably I never made cool looking units. And everyone know that ;)

[[XC] gomeler]

Luke, you are definitely known for your own style :D The condenser fins are simple, a few passes with a brush and they'll straighten out :up: Looks like that insane mass of pipes that you call a first stage is doing it's job well, you surprised me there :eek: This should be a great Phenom II cascade, not many other chips can take the cold this thing could produce :up:

[Moc]

Everyone who bought a unit from LukeXE knew how the units will look like...
You know that it's not very intelligent to vacuum with an old 1/10hp compressor and than fill with an flammable refrigerant ? :rofl:

[LukeXE]

For me it`s okay. How much air is inside after that vacuum ? 1%, less ? For me that amount is safe, not explosive.

[symphy]

And another week without activity - or did you finish the unit without posting the progress?

What is wrong with you, what the hell are you doing? Do you think this is not serious? Do you think i'm not serious? You're showing nearly no effort....

Get this unit ready until the end of this month or we're finished. I'm prepared.

Imagine what happened to me - we're talking about much more than 2000 USD. You just took it, and i want it back. Get the unit working or pay. As easy as that.

No PMs please. No MSN chats. JUST DO IT. And don't think you can deliver an instable running pile of trash. If you can't build that unit, just give me my cash back. If you can do it... i'm waiting for OVER 2 YEARS now, be sure that i've my own thermal probes and my own load tester... Don't try to fool me with something that's not worth the money i paid. But, even here: If that's not possible, give me my money back.

[LukeXE]

building 3 stager is not simple as it looks. Especially with methane. So please don`t tell me that there is no effort from my side. If you wanna "pile of trash" I can deliver it even in this week. At first it looked like easy job, but it`s not.

I know you are waiting almost 2 years. but we talked a lot of times, that you`re not in hurry and I can finish other delayed units. I finished them and now working on yours.

You`ll get working unit which you wanted from me.

[symphy]

building 3 stager is not simple as it looks. Especially with methane. So please don`t tell me that there is no effort from my side.

What did you do the last week? No update, nothing. You always have an excuse for everything, but in fact you were just not working on that unit. That's what i call "no effort". Building 3 stager is difficult, i know, but if you dont do ANYTHING, you'll never see if the unit works or not.

I know you are waiting almost 2 years. but we talked a lot of times, that you`re not in hurry and I can finish other delayed units. I finished them and now working on yours.

That's the point. You just accepted a job without knowing how to do it right. We've all seen that the first try just did not work. You say "now your working on my unit" - what the hell? Which other units you had to finish since the beginnig of this year? If you really were working on this unit you would have posted pics showing the progress INSTANTLY after my last post. But you didn't.


You`ll get working unit which you wanted from me.

I wish that would be te truth, but it isn't. You're always moving from one deadline to antoher without finishing the job.

Look, you build two stages already, so why isn't there even a design for the third one? If it's that difficult, give it try instead of doing nothing.

But deadline is not moving. Two weeks should be enough to rebuild third stage 3 times. And if you make pics the next time, please take them of the entire unit, not only parts of it.

If there's no acceptable loadtest until the end of this month, we're finished.

[LukeXE]

Hello

The problem with not "constantly" updates, that I started new job and I can work on weekends, cause I`m so tired. After work I`m going sleep and wake up another day at 5am and go to job and so.

I wanna finish that unit and be clear with delayed units.

I`ll make loadtests. Hope to see good results, gotta new experience from job and will make 3rd stage as it should be done.

I tought that earlier photos show whole unit

FAIL. Between your last update and this weekend was another weekend. Did you just miss to upload the pics? Luke, be honest, nothing is going to happen, and i'm saying this without even rating the build you did until now.

Deadline is not moving. The unit was standing ALL THE TIME inside your cellar for the last two years (am i right? i should be cause you told me that you didn't took the parts for another unit...)

Where are the large compressors i payed for when we discussed the unit? 18000 btu etc.?

I don't want to talk about this topic anymore. Go wo work, hopefully that will bring me at least a part of my money back. Or build that unit until end of this month. Point.

[Simps]

Holy crap! No one told me this thread was da sh/t!
Man, there is no way in hell I would pay 2000 bucks for a unit that looks like that. That thingy will need maintence and repairs twice a month at minimum. And it doesn't look safe at all. You keep that unit running for 24h straight and it will explode for sure.

I feel so sorry for the poor guy that lost 2000 bucks. The way I see, he already lost 2000 bucks, recieving the unit at the end of the month, or not. There is no way for him to get out of this one winning.

[tiborrr]

Simps, may i remind you to f*** out of this thread kindly, you don't help at all :rolleyes:

[teyber]

simps your post will be deleted. GTFO out of this thread.

all i gotta ask is,

are you drunk?

what you are saying is plain wrong. the unit has been leak free for 2 years, the part that looks like sh~t is the fins on the condenser which can mostly be fixed

[symphy]

Guys, stop flaming this thread. If he wants to state his opinion... it's okay. There's no need for blaming anybody.

I don't know, but i wouldn't call anybody to be drunk without even having read the last page of the thread.

The unit isn't leak-free for 2 years, luke rebuilded and rebuilded it... i dont know, often enough. This aren't the components i paid for, no idea what he did with them.

Be nice everybody. If some1 read the last pages of this thread, he'll most likely come to the same point like simps...

And, sorry, insulation made of a paper box, to small baseplate, that pipework? ... No one even thought of bent fins...

[Patrickclouds]

i would mount the desuperheater in a proper way.

it only lays on top of the coax hx box.

or it won´t survive the shipping, if it will ever be shipped :D

are there any high pressure cut off switches installed?

[Moc]

And, sorry, insulation made of a paper box, to small baseplate, that pipework? ... No one even thought of bent fins...

But LukeXEs Units looked to every time like this. And for a 3stage 2000Dollar is super cheap... didn't you know that it will look ghetto as you bought the unit?
No offence to you or Luke (...)!

I can accept a unit that actually looks ghetto, but is working fine. As Luke already said, i'm looking for good performance. But there's a big differnece between "not good looking" and botched up.

Beside this, the acutal amount payed for the unit is over 2000USD and i had other offers from builders. It's not super cheap.

It won`t explode. It has relief valve and two cut-off switches.

I see you`re very experienced to know how often units has to be repaired ?

fins will be ok, I got tools for that, but will do that as the last thing.

At all, components for your cascade changed...yes...compressors are much more stronger than last ones, which were too small.

Auto-c stage is leak free, it was leak free for almost 2 years :)

Why you talking about usd, you payed me in euro :) think about bank transfer rates, bank exchange (I don`t have euro here) and think about that, you payed in two parts, with dissapearing for few months :)

[Simps]

Luke,

I just finished reading everything on that thread "Finishing delayed units by Luke, information topic".

I see you have serious problems going on with your custumers. Problems like refounds, delays, communication, etc.

But it also seens like you have been working hard to clear that mess. After reading everything, I don't think you are a bad person, or that in any moment you tried to fool your customers.
It really just looks like things got out of control for you, when you started to do a lot of units at once, and all the international shipments, and a lot of problems with units, shipments and personal life happened at same time. You are just one man, not a company. Probably, if you had accepted only a few units at a time, you would have been able to it the right way. The hard part is that even if that is the true, it shouldn't matter for the custumers. The pay, they want you to keep deadline and deliver 100% of what was commited. So even though I believe you had always the best of intentions, I have to stay on the custumers side, because that is the way things should work in business.

Anyway, I hope you can clean everything, and get out of this mess.

But you should really think of building cleaner units. I won't take my comment back on that. A unit that looks like this one (this 3-stage mess) is totally unacceptable for selling to customers. For a personal use, it is fine, but this is not the case.

Anyone saying that the unit is not that bad, is saying this because its not their money paying for it. I doubt any reasonable person, would be happy to pay even 1000 bucks for a unit that looks like that.

Anyway, I wish you the best Luke.


symphy,

I wish you the best too. I hope that luke can find a way, to make, in the end, you happy with your acquisition. But I really doubt that will be possible at this time.

i hope that it will work but i don´t belive it until i see this unit running with load.

in my opinion that unit is to small calculated in all points, but we will see how much load it can handle.

[teyber]

o man hes only got like 5 days left :(

[LukeXE]

Sorry guys

got a lot of work from sunday, havent do photos actually yet. 2 and 3rd stage holds pressure for 2 days, so I assume everything is okay.

Today around midnight I`ll paste some photos.

[LukeXE]

ok, gotta 4 photos, unit is insulated in let`s say, 90%. not insulated fully due the leaktest.

I`ll do better shots tommorow after vacuum and filling with gasses. I`ll do shots in home, not that mess like in cellar.

Not everything connected, like expansion tank, manometers and cut-off switches. Will do that when cascade will work.

L.

[symphy]

:) Cascade is looking better, even it's still a bit ghetto. Well, I expected that :D.

I'm glad that you finished most of the work before deadline and i'm sure you will finish the entire unit right in time, too (everything beside filling it with some gas...)

Don't hesitate to contact me in ICQ ;) - seems like everything could have a happy end. ;).

Is this unit moveable ?

[symphy]

with two persons it should be.

According to Polish and German time zone GMT +1:00, 7minutes left :rolleyes:

[symphy]

He finished all stages, we're in good contact so I'll wait for load temps.

[LukeXE]

Hello

I just wake up :) Worked to 5am in cellar.

The news:

3 stages are working :) With Ethylene on 3rd stage I got -135C, my camera dead so I`ll do next photos today. Did some of electric.

Next news, I`m waiting for co2 and propane to add some to 1st stage, because it`s not even calibrated to handle, at all, huge next 2 stages load. When -135C on evap, on 1st stage temp drops to -35C (0,5bar suction), so needa to fill it with more gasses.

Third news, I found leaking suction valve on 2st stage ! Not brazing, not core, but "case" of valve is leaking ! Freaking :down:

I just wake up, uploading photos which it was possible to do with my old batteries. Today next day of fighting :)

And Mateusz, be more insterested in your study egzams terms than mine deadlines. Thanks.

LOL, and I repaired condenser lamels. And I needa 2 thermocouples, because it`s hard to use only one for 3 stages :(

[Patrickclouds]

did you already ordered the gases for 3rd stage?

[LukeXE]

I`m thinking about ordering more R14, because I got some, but not much. Methane got already.

[Unseen]

What i really like in you Luke is the motivation. I am sure you will finish this project.

But from the other hand i am worried about the safety...
Bad combination= electricity,water from uninsulated parts,metal stuff without protection,flammable gases,no color codes

Honestly if i was still in Greece i would have build this cascade for you,with your parts for free, just to help you exit from this situation.

Anyway try to keep it simple and to be safe! Maybe you know what you are doing but the customer not!


Ps.Sorry for posting but i couldn't resist :(

[LukeXE]

Wait for finished project ! :) Everything will be 100% safe !

Thanks for comment Unseen :)

[yotomeczek]

Wow !
My old - never working cascade :D
And still some problems ...

[LukeXE]

From your cascade is only the first stage.

And needs to be tune. What problems ?

I see that that comments post only people who never did auto-c or even 3 stage.

[teyber]

luke its coming together great :)

i a noob with auto-c's, so forgive this stupid question :p:

when an auto c stops autocascading, say like you said you need more co2/r290, what does this mean? is your problem like in a ss its just undercharged, or does it mean that there is not enough r290 do fully separate and condense the co2?

Thanks dude, sorry for the stupid question :)

and keep up the good work!

[LukeXE]

No problem with that question dude.

Yeap,it`s something like in SS, unit is "undercharged", there is too small amount propane to give proper temperature for co2. Next, if co2 isn`t condensing properly, there is too high temperature to condense ethylene. IF ethylene isn`t giving good, low temp, whole cascade sucks, because Ist stage temperature sucks.

At idle it can be ok, but under load everything changes.

[MaSell]

And Mateusz, be more insterested in your study egzams terms than mine deadlines. Thanks.
I don't have any study exams, because I'm not a student for long time:)

Could you show pic with mounted evap to mobo? I wonder where board must be placed to bench without too tight suction line.

[ultralo1]

I am glad to see good progress. I know its none of my business, but keep up the good work and relations. Two thumbs up for you.

One question for all the Polish people of this forum, especially MaSell & ryba. Why do you always have to bash Luke, after all you got your money back. Move on. Why can't you be nice and polite or just try to avoid topics you know you'll write something inapropriate in? :shrug:

I think, that it is a habit that some people in our nation have. They just love to judge and wish to punish those who (in their opinion) are guilty. Probably, it is a result of our nation living under the comunism and control of Soviet Union for quite a long time, and the fact that it often happens in our country that lawbreakers stay immune to the law. People suffered being helpless, their children learned the way of thinking from them... Sometimes wounds need a lot of time to heal.

I also think that an additional element of attackers having a need to raise their self esteem has played a role here.

Luke, I've been observing your situation for very long time and I have always wished you the happy end of this mess. Keep up a good work, you can make it. Don't give too many promises. Just post photos when you have them.

No, there is another problem. Some ppl know much more about all situation than others. That's the point. My self esteem is pretty good I think;)

BTW Nice bike Luke :)

EOT I'm waiting for nice loaded temp... I hope that will be very soon

I think people not involved need to GTFO.

[Patrickclouds]

and i think that you thought wrong or cannot generalize that ;)

because people (not involved) but knowing how to built good working cascades should be allowed to give hints to get this unit running well and safe.

[LukeXE]

I got nice, strong, 16k btu rotary compressor from work. I`ll change compressor from I stage, because with 3 stages working I got only -45*C, with loadtester it goes up constantly, probably because I haven`t calculated captubes lenght for that big load + compressor, as few persons said, is too weak( I got only ~ +0,5bar suction pressure, to small flow).

And I have small question, do normal I stage with that 16k btu compressor, filled with R404a or play with captubes in that auto-c. Today I have to made decision, to start working by weekend.

( I got only ~ +0,5bar suction pressure, to small flow).

That doesn't mean that your compressor is to small, that shows that your captubes are too long.

If you put in the same unit a stronger compressor, the suction pressure would be lower. It "sucks" more - so lower pressure.

I would shorten the captubes and put in the new compressor. But I doubt that you get the autocascade working. I know how much work it is, trust me, I spend much time in this (and will spend more ) :D .

If that doesn't work, try a TEV the first stage. I don't remember what others compressors follow, but a TEV is always the best.

I want to be the first one saying that this unit won't be ready before 2010. I will quote this in 2010 :)

I disagree. Even if he has to adjust the capillary tubes, he's only got 30 to 40 hours of work left. This can be done in two weekends. I also agree, drop in the stronger compressor AND adjust the capillary tubes. Just getting the 1st stage HX temps down from a "normal" -30C to -60C will drastically help reduce the strain on the 2nd stage condensing R1150. I however think he should use a hydrocarbon blend of R600/R170 or R600/R290/R1150 instead of R744. This is just personal preference and hatred of R744 dry ice issues though :D

[LukeXE]

Ufff....

I stage compressor changed. Gotta few problems with neighbours when I was gettin out gas from that stage :down:

Unit is so small that compressor change is pain in the a$$.

Yeap, I know that. I got 240cm of captube for R1150, I should cut it to around 200cm or less, other captubes cut that same, around 30-40cm. A lot of work, but it`s necessesary.

don`t be so pesimistic !

I would like to use R170. If I would have it :) Or even R23. Dreams. I can try with R600/R290/R1150. No problem. But I need more thermocouples to get good temp readings.

With symphy we wanna working auto-c stage. The last option is just do normal I stage with TEV.

[teyber]

do you live near berkut? doesn't he have a lot of r23?

cheers

Tell us more :D sounds funny. :ROTF:

[MaSell]

It's not funny at all. I guess neighbours were unhappy, because someone was playing with gases in their building. They could think that it's dangerous, can explode or something.

In my opinion, getting out gas in building where is many flats with ppl, isn't smart.

[Moc]

MaSell, I do not know how he lifes, I didn't think of neighboors in the same house.... my fault, probably your right :D .

Sorry, I know we are not in 2010. I am just practicing this quote thingy. Won't do it again, I swear.

Stop being a :banana::banana::banana::banana:.

[LukeXE]

Got crazy papers for this week.

Changed captubes (I cut them for 40cm, each one). Brazed. A lot of f**k to do that.

Need to get some more propane. I`ll talk to berkut about R23.

[LukeXE]

Next info :)

On saturday will come to me friend who is doing phase too and we will work on that build together. He will bring some stuff, like vacuum pump, his own torch with oxygen so we will do everything what possible and make it working :)

We will do a lot of photos

[tiborrr]

Thats great news, Luke! :) Just please post the pictures as soon as possible and not few weeks later :up:

[Moc]

"The thread pusher was here :D"

[LukeXE]

Thanks my friends :p

Friend refused to come, because he has short time driving license and he was afraid because of long trip.

SO I`m doing everything by myself. But I got only one arm, because left one is domaged from my jump from university hostel (long story). So I`m on 14 days medical discharge and working a bit slower.

I just have back from rehabilitation from Busko Zdroj (town with a loot of rehabilitations centers), so I`ll try to upload photos tomorrow.

[eligray]

I`ll try to upload photos tomorrow.

Over-a-month-since-pics-promised bump! :D

[[XC] gomeler]

I was thinking about this build the other day actually, as I'll be doing something similar and was hoping to see how it works with this build. Finish it up so I can convince myself it is a good idea :p:

[noobzed]

this project is dead, i want to know, if possible, the feeling of the one who comissioned lukexe ...

[Ozzfest05]

Just what the thread needs more negativity...

[ryba]

Just what the threaded needs more negativity...

After two years you want have any optimism post? Yeah, good joke.

[tiborrr]

Any news on the 3-stage monster?

[clear cmos]

@LukeXE & symphy : any update guys?

[ryba]

Now I would like to hear apology words from ppl who didn't believe me that this unit never will work :D

[Kizmo]

Three years...

You still owe me some money Luke

[sdumper]

I was wondering what ever happened to this build. It looked really promising.
