My singelstage unit ( to beginn with ! )

[Zejtan]

Yepp, finnaly i have gatherd some of the parts that i will need to be able to beginn building my rig. Im gonna start as making it a singelstage, just to eliminate some of my question marks away, and after that, there will probably be some larger modofications on the rig to make it, how should i express it, coolder ? ;)
Just posting some pics of what i have planed to build with so far,
Chilly and all other are wery welcome to share their thougths on this, it will only contribute to more wisdom.
Except if you are going to complain on my english, becase if you are going to do so, you can go and ----- ! :toast:

Ohh, and by the way, the guy that sells the baker block i have managed to get my hands on, has he become a ritsh man yet ? with thoose prices, it seems not be any problem :D

Anyone who have blocks to sell are wery welcome to e-mail some info, pics, and prices on it to me, i would like to get my hands on, ohh, lets say six to beginn with if the price is right.

Nice compressor, isnt too big for your rig? :P just kidin, but i was using sc15g so i can imagine how powerfull is that model ;)

[sharp]

This compressor is strong and its gonna kick some ass.

[100]

I hope swedish electricity is cheap :D
GL with it mate.

[Zejtan]

well, in the future, this rig might not be fore one singel purpose, therefor i will need the extra size on it, the best part is, i have four more of this compressors :D

Thats why i choosed it, strong means vacum ! vacum means coold =)

I dont pay electricity, its allready pain for in my rent. although, my rent is the size of texas....

[HawainPanda]

u have some too many shraeder valves lol, nyways..neat

thats the reason that i inserted them all into the picture, just to see how long it took for someone to comment on them. congrats, you won :D

but hey, its better with lots of them, then none, right ? =)

You can´t use this thread on your eva (won´t be tight)

im not sure i understand what you are meaning, but if i where to make a guess, i think it is about the 90degre bend that the suction line is to be attatsched at.
If so, i bet you i will get it "tight" :)

[Vinci]

but if i where to make a guess, i think it is about the 90degre bend that the suction line is to be attatsched at.

yep, exactly
braze connections are the best and safest connections
well, i would braze it... I´m almost sure, that it will leak :D

/edit
i think i need a english language course :p

[Zejtan]

i will braze the bend. i assure you, it will be leak-free.

Lets have an english course together, chilly1 may be the teatcher :D

[Overklokk]

Hey!

Good too se you back building phase change Zejtan. It looks realy nice so far and i bet it's going too get realy cold :)

BTW: Ask Chilly1 about evap... i use one of his in my casade and its a realy great evap.

Hello there Mr Norway =), it's been a while, how is the cascade building going ?
yes, i will ask him about his evaps as soon as i can remember to do so,
are you satisfied with them ?,
they look really really god.

The Cascade is upp and running but only with r404/r410a so far.... Must get som money too by the r1150 soon :)

I like the Chilly evap realy good so far.

I hope too get some money soon so that i can wisit you with my r404a bootle :)

You are wery welcome to visit me, ill make the coffe and if you are lucky, ill even throw you a bizkit :D
Ill bring the 404 bottle home tomorrow if i can remember it.
So it is here when you arrive.

[berkut]

flex hose ?

[Zejtan]

flex hose ?

Will be in the pictures soon.

[Unseen]

very nice! keep going!

[kayl]

nice lots of parts hehehe
brazing to come
what size is the compressor, cant wait for the cold

[Epsilon]

21cc compressor
www.danfoss.com for more info :)

In fact that is the biiiigggg brother of the prommy compressor ;)

[Zejtan]

Kayl, here's a pdf on the compressor, its a nice little thingy i belive :D
http://www.modkjol.no/wh/mk/MKDokume.nsf/43f94b7c487bea46c125690c0041418d/85243fa7f96984d4c1256c2b0043c56f/$FILE/SC21G_R134a_220V_50Hz.pdf

just have to say "holy testicles", the price for the start equipment was Not s cheap story, and the flexible suction line hose was expensive as Hell !
But, they are still on there way, will begin building the system on friday, hoping to have it "pretty" mutsh done by sunday, with some luck, i can use the weekend after that for the oc part =)

[Zejtan]

The final parts arrived today, and Got Damn they where expensive !
just so that i know, what do you pay for a flexi suction line like this one in the us, or where you are located even. ?
The startkit for the SC21G was a frikin tripp to the south, ok, half the way at least !

[gkiing]

I pay $12cdn which is about 9$ US for a 24" suction line, but its not all stainless (but it doesnt leak over time, its sort of like an auto a/c hose).

i belive i know what kind of hose you meen, i have been thinking of one of thoose to, but i went for this one due to the fact that i belive this stainless steel hose is smoother and easier to use due to it's flexibility, the ac hoses are actually kind of "stiff" in my opinion.

[hatemi]

Around 50 euros for 1m stainles hose.

do you have a link to the place that sells them,
would be great =)

[Farbror]

Hey nice :D
Zejtan how about you make one for me to (4free) :slobber:

[hatemi]

I bought them from Dunlop Hiflex and I believe thy have shops also in Sweden. My hos has bit different fittings but the price should be somewhere around that nonetheles. Maximum operating preasure is 75bar and temp is -200-600c.

Yepp, they have shops in sweden aswell. That's the place i bought the two hoses i have, but when i bought the a/c hoses i have i didn't know they carried ss hose too...

[Zejtan]

ill better make a call soon to get some of thoose hoses then, cant harm to have a couple of them in the shelfs =)

[hatemi]

I'll get my new hose(with different fittings than the one I had before) tomorrow. Then I'll post some new pictures of it and get my unit finaly running. Atleast I Know that my evap finaly holds preasure:)

[Zejtan]

post some pictures of the entire rig, or do you have a thread with your setup in ?
post link so i can have a looksie at what you are doing.

Eiisa Päitaa ! =D ( speeling wrog ok ok ok, but it is the only thing i can say in the finnish language ! )

[Zejtan]

Well, howdy folks ! =)
Today i finally got my ass out of the wagon and draged my 2 "new" units home, they are from a "thing" i rebuilt at work, so, they where, how do i say it, leftowers ?, and not nedeen anymore :D
So hey, they might just come handy for me.
The units are
FH4525Y
And
FH4518Y HR
Some pictures for thoose who like that.

http://upl.silentwhisper.net/uplfolders/upload9/aggregat_2.jpg
I also caught some pictures of my Ac unit that i have laid my hands on a couple of weeks ago.
This one will probably be something fun in the future, if i dont sell it, or install it at home :rolleyes:
The cooling capacity is pretty big so it might be able to get som -temps on a cpu :p:
13000 Btu, is something like 3800 Watts if i remember the btu in Watt correctly ?

Din Finska språk är ganska daligt men jag kan språka Svenska mycket bätre :am: Sorry I'm somewhat intoxicated and just had to test what I remember from my swedish lessons:) I'll have to admit that I have always been one of the worst stundentis in that subject in my class.

Here is the link to my curent projects and you can find a link to my first phase change system in my first post of that thread. More updates coming this weekend if averything goes as planed.

damb they are some sweet compresssors.
i want one hehe

[berkut]

Am i seeing a future cascade ?

[100]

zejtan has the right hands for his ideas :)

[Zejtan]

Hatemi: Din svenska är lite rostig ! Jätte rostig ! :D but hey, your swedish is hell of a lot better then my finnish =) ill have a looksie in yor page later, am leaving home soon to start build this thingy of mine.

Kayl: Ewerything is for sale, ill even let you have one cheap, but the cargo/freight ? to you will be a pain in the ass i belive =), but if i come to australia ill bring one for you, you can buy me the trip and get them booth for free =D

Berkut: i dont know, can you tell me what you see, you might just be one of thoose that can se the future, =D ( but it might just be that it looks wery mutsh like it =)

100: if i had moore hands i would drink more beer ! =F =D

[hatemi]

I now have the new hose and it cost me 55e. I'll post some pictures of it as soon as my camera battery has recharged:)

[hatemi]

Here's my new hose. The pictures are somewhat crappy but hopefully you can see some of the details:)

[Zejtan]

nice one, is that 55 Euro, ? ( yes i guess it is... )
Ill might buy some of thoose from you, will have another check in Norway/sweden if i might be able to find anyone else with these hoses, and dont charge a fortune for them... =)



But hey, i have made som progress today, i think !.... :D

http://upl.silentwhisper.net/uplfolders/upload1/Frostad_evap.jpg


And now a Question for thoose who know.

-What length of capilary tube would you suggest i should use ?
Lenght in Meter or cm, and 0.028" tubing.

[hatemi]

Yes the price was in euro. It depends on the fittings but they shouldnt get much more expensive even with differant fittngs. I think you should ask for them from Dunlop Hiflex in Sweden. But if you cant find them I can order some and send them to you:)

[Zejtan]

-Update-

Well, i have started building the system, and have made some changes on the way, i aint satified with it yet, so , here are some pictures of the rig,
i wont type any text for them, because im going back to the place where i am building it. Hoppefully, i will get it finnish it tonight !, I have a computer at that place so ill might pop in here and have a looksie for posts in this thread, untill then here you are, some pics of the system. Im not wery fond of the temps yet....

[JSU]

wow looks like you had a nice leek

[gkiing]

Were you trying to use the stove to simulate a heat load? I think the stove burner is a lot more than a couple hundred watts...

[Zejtan]

When i arrived to the place where i do the work on the unit, i light a ciggaret, leans forward, and see a small boubble growing slowly on the evap block.
I wanted to kill something,
ahh well, i thought. lets just make a fast soldering oh that little spot to make the solder flow out on the leak. no problem ? yea, right....
the bottom of the block snapped of sending the hoose on a journey around the solar system....
So, i duct taped that sucker to the frying pan, except i didnt use duct tape... because i where out of it...

The rig has been on vacum since 01:00 ( swe time ) and i am now going to try it again.
afraid that i have totaly ----- up my backer", but hey, atleast i have learned something from building this rig, as although it is my first direct dye rig...


**edited for language content - please stop using the "F" word in any shape or form. It is against forum rules.. runmc**

[sharp]

Well you see at least nice frosted evap :D

[JSU]

um yeah flares are hard and dont braze with gas in there. Besides the fact its a flare joint.

[chilly1]

Use flare washers... Or don't use flares at all, I am going to braze in line only from now on. Found a good US source. And Ya bakers are hard to braze too. CLEAN CLEAN CLEAN, And use paste floride base flux even with the 15% silfoss it makes the braze more oxide free.

[Zejtan]

Sharp: Yea, thats about it... frost, but not cold...

chilly1: i didnt have a leack there at first. but after i had to re-splder the block it loosend and leaked... but i couldnt tight it enough to macke it no leack again, so i went psycho on it and solderd it thight... and i DOnt like these baker block's any more... i will have to make one of myself. due to the simple fact that i cant afford to buy anyone elses...

But i have som problem with my system, i can se the problem, but i would like someone elses opinion on the system, i have made som mesurements on it, so chilly, and anyone alse that has a clue on it, plz feel free to make me feel like an idiot and tell me what i have made wrong, the presure on high side makes me "go figure", but the suction presure is "looking good", but the temps on the evap makes no sence to me...
feel free to commennt, because i realy need to get this rig up and running.
I was aiming for atleast -55c, but ended up with a wery expencive pice of copper that makes noice...

System mesurements

Evap -23,3c
Inlet compressor +7,2c
inlet condenser +17,2c
outlet condenser +9,3c
filter inlet +8,9c
outlet filter +8,9c
Air in on condenser +7,6c
Air out of condenser +9,1
Room temperature +7,2c

compressor top is "hot" not burning, but warm.
compressor bottom is "hot" not burning, but warm.

R507
Suction pressure is -0.6 Bar ( -60c )
High pressure is 7 Bar ( +9c )

All under NO LOAD !

The capilary is aprox 1.6 meters ( 160 cm ) of 0.028"
I have a feeling that the hp is Way to low for this setup, but i have tryed to "yank" it upp by blocking the air on the condenser, helps wer little, might get it to 8 Bar or so.
I have been thinking that the condenser is Way to big for this system ?
i started with 2.4 M ( 240 cm ) of 0.028, and have shortend me down to this for some reason.
The lowest temp i have had on the evap is around -30c.
The vacum i have had was 4 mBar in well ower 10 hours before the mesurements above was made.

Plz, if you have a good idea of what i should to. plz let me know.

Best Regards
ZejtaN a.k.a Ted

[chilly1]

Add more gas and run the pressure up to -.2 bar. The get the inlet and outlet temps of the compressor the condenser and the evaporator as well as the pressures.

[Zejtan]

i habe tryed that, i get way more frosting back to the compressor, the temp on the evap block isnt geting "mutsh" better. and the high side presure dont go up by mutsh, but the evap suction preuser is rising if i do so. i am thinking that maybe there is something "jammed" in the block that dont alow the gas to evaporate where it is ment to do so, that it takes a hort-cut or something back to the compressor.

[chilly1]

You will need 3 meters of 0.028 capillary tube and a suction pressure of -.2 bar. Should give you -50C with R507. It should frost all the way back to the compressor with the line insulated.

[Zejtan]

Aight, then i will ripp this "sucker" into bloody pices as soon as i get time to do it, probably wont happen untill next weekend but hey. lets love to wait, time is our friend.....

I will go for your 2 meters of 0.028" tube and suction -0.2 Bar Chilly, my god i hope you are right. But hey, you know this things better then most of the members here so i will follow your command :D

// Zejt

[chilly1]

3 meters....
I got a R507 system runiing 9 ft .028 at -53 degrees.

[kayl]

when you turn off the system how quick does the thing take to equalise.

cool pics are fixed, man ya crazy, i can see ya had fun with the stove as the heatload.
as long as it doesnt leak (patch it) and sand the bottom nice n flat and polish
should be able to use it then
also why use fittings at all, just getting the hose and braze copper pipe to steel flex hose, leak free now no screws to worry about.

[Zejtan]

3 meters....
I got a R507 system runiing 9 ft .028 at -53 degrees.



It's not that i dont trust you, im just an idiot and have to act like one to =)
but i hope you are right. and i will try your advise ass soon as posible ( friday it seems like )

kayl: The frying pan does not act as a heat load, it is just so that i wouldnt burn the place down when i solderd the block :D but it look's like Predator raged thrue the joint...
The system equalises pretty good according to me, but it seems ass there are no liquid exiting the capilary tube, just gas, makes me wannt to try chilly1's advice on the "fill it upp untill it works" theory about the liquid that stays in the kondenser.


And now, i am going to sitt down to draw a evap design that i have in my head, and take it to a friend that i just realice can make them in his machine that he has, IN His Garage !. i have been serching like a fool for someone that can make blocks for me, and the dude is my neighbour....
sometimes life acts funny on you...

[Smolly]

Looks like the captube not entering the blok completly but entering the suction line.
Gas is suct out the captube and goos directly in the suction line .

So no decent presure on hs and even a litle gas in the system gif's u frost until the compressor .
My 2 cents :rolleyes:

suxes wit'h u new block ;)

that thought have crosed my mind to,
i also noticed that the solder had went into the channels, not good.

I am going to get a sampel of my blcok now, will be back in some hours with pictures in a new thread then.
