#2 pic, note the foams scraps next to the exchanger
Getting there :D
Note that the exchanger will be ~20 cm above the baseplate, beneath it will be the II stages drier and probably the oil separator
Great pics and how to....I think it deserves sticky. :D
Can you change the topic to smth more related to the subject than "My newest toy ;]"? it sounded good with the single stage version but this is more like a walkthrough..
Done :DQuote:

So nice very good pics also!! i could do this just by the pics!! good job!!
Ok, making some new stuff :D
First thing for today: The mobo, hdd and psu tray...
Its basicly a box made of wood, with some sound damping mats inside, in it will sit my antec true power 480W and my Western Digital WD800JB, the necesary flow will be provided by the antec and 2x 80mm fans @ about 5V (depends on the antec will provide on its fan only molex)
Pics of the tray being mounted:
Notice the maze inside, its made so the sound doesent come out easyly ;]
2nd pic of the tray
How will the psu be mounted (1rst idea but in a matter of few minutes ill post my second one)
OMFG
Bowman, Macci, and the rest of you guys, this is smth that is one of the worst nightmares wich you can imagine :slobber: :slobber: :slobber:
:slobber:
:slobber: :slobber: :eek:
In the words of monty python and the quest for the holy grail...
"run away, run away..."
Was that the high or low side? Hopefully its not too bad to fix, and that your ok...
]JR[
that was your high stage right atleast better to have R22 in your house then CO2
You are experienced, but I see some guys telling noobs to use propane, not to worry.
Just goes to show that even very experienced guys can still have things go wrong. If this had been a noob with propane, it could have been bad news.
glad you ok bud.:)
this is why i always pressure test the system before i fire it up.
i see just a simple solder joint.
so you will up in no time..:D
be sure to clean that tube real good now.the leaking refrigerant will put oil into the metal and brasing or solder wont like that.
clean,clean,clean.then solder.
you are right, that is a nightmare. what kind of fitting gave away, is that a flare fitting?
was the connection brazed or soldered? (edit: bowman beat me to it.)
atleast nothing exploded (copper shrapnel comes to mind)! i hear cascades can explode if the low stage isnt condensing properly.
that is why i do all of my filling outside hehe, always plan ahead...

yep if the cascade high side loses charge its evaperator wont cool the low sides condensor enough and the compressor will start to raise and raise until one of 2 things happen.
compressor cuts off from over heat and pressure or......BOOM......:frag: :frag:
a line explodes,a fitting,somthing.it wont be nice.thats one of the risks involved in making a cascade system from scratch.
wow i cant believe u got pics of it happenin! i woulda ran for the door!! sorry man is it an ez fix!!??
If that would be a noob with propane there could be BIG trouble, but a pro with propane... nothing would happenQuote:

Its kindof windy now and i simply opened windows and it all was flushed out...
The second thing with propane is the fact that normal systems have MUCH less gas inside them, usualy propane is used in small DD systems, this is a I stage of a cascade O_o
And yes i use R22...
It survived the pressure tests... It didnt survive shutting the system down when the pressures started to eqalize and the temp of the copper pipe went down (its near the txv) radicly... damn..Quote:

I had my digicam right on my desk and i was eating my dinner when it happened... I already knew that i couldnt stop that mf leak so i grabbed the cam and started making picsQuote:

I will have a pressure relief tank in my system. Ive already had an accident when i didnt close my service valve on the compressor and it sucked air inside... Simply went to ~25-30bar and the air went through the cap tube...Quote:

The system redone
