Got a start to the autocascade to night.
not much but im going simple on the hx, just split on the hx & SLHX.
Start with the kayl block.

The HX is made up of 3x 3/16" inside of 5/8".
total hx 5m with 0.031" capillary feed.
Looking good so far. 3x 3/16, that must have been really fun to push through the 5/8....
I never tried CLR on the evap, how much does it help clean it up?
I used to have links here demonstrating how awesome I am, but it's been so long that they're not very relevant (and the pictures have disappeared), so I guess I'll have to get working on new stuff.
only takes about 30mins to clean.Originally Posted by eshbach
then i wash in water and lap on sheet of glass. You want the one that doesnt contain phosphates as that one doesnt work. It justs goes blue and takes ages
i 've never seen before an oil sep in an autocascade....what did you use to build it?

can you use it inside the evap? or does it leave a residue? [i have nothing but propane to purge with, might try it later though.]
Copper tube with copper/steel wool (or sth) inside and that`s it.
btw, nice start Kayl, I wish you luck with this auto-c

but the oil sep i think could create problems in an autocascade i think that this sep will sep oil and a little the two gases...so on the bottom of the copper tube there will be oil and some liquid gas....i hope that i'm wrong...i think that in an autocascade an oil sep works like a phase sep..
what gases what compr give more info
Probably Kayl will use hand valve for the oil return
If he will install an oil separator before condenser, so there won`t be any of liquid gas inside, only oil on the bottom and that`s all. I`m pretty sure that Kayl will use hand valve for oil return.

nice and clean start kaylYou are talking serious business with the HX
looking good Kayl, one question. Why is the suctionline brazed up so high?
Nice cube condenser with shroud. I still got 2 of those!
If you have a cooling question or concern feel free to contact me.
Thanxs guys.
the CLR clear is acidic so using that to clean the inside of an evap is a big no no as it will turn the oil acidic and destroy your compressor.
you can purnge with propane (would only do cpu evap and nothing else).
but be careful, feed it dont the capillary line and dont use more than 5psig of pressure. co2 argon or nitrogen are a better choice though.
Woops. Hawaiiparty when I typed oil separator I was ment to type phase separator.
Its just the usual phase separator after condenser feeding in from top. The first stage refrigerant will carry the oil with it and condense into a liquid and collect at bottom before feeding via capillary line to the HX. The high stage refrigerant won’t condense and will travel back out the top of the phase separator and pass through the HX to condense. If I have trouble separating the 2 refrigerants as they are both hydrocarbons will add a small suction line HX before the phase separator and insulate the phase separator as well.
I was going to use a 1/2Hp r502 compressor then try a 1hp rotary later but, I think ill just use the rotary straight away so don’t waste gases. Ill be using propane and ethylene so getting it to work at load is gonna be a big challenge.what gases what compr give more info
thanxs johann, Ya referring to the suction line tube leaving the bottom of the HX?
Its that long cause that’s where ill be attaching the stainless steel flex line with the kayl evap. At the top of the HX ill be connecting that back to the compressor for now.

the hx is finished and pressure tested
did some work on the autocascade tonight.
just got to add the compressor from the cascade and vacuum now.

Great, great, great !
thanxs lukeXe
i got it going but i think its not running that good.
Needs to be insulated and maybe shorter capillary line.

I see you have -64,X temp on evap, good, I tried today that same and I had -65*C on evap with ethylene too.
Try to put filter before HX, I heard that filters in sub-zero temp won`t work that same like in ambient temp.
I`m sad that I don`t have ethylene now, and I must go back to the co2 division
I`m glad that we have still more working auto-c in that competition !

Hey
What`s up with auto-c Kayl, any progress ?
Maybe he's in a tuning fight
CASE Sharkoon Rebel 12 / CPU Core i7 920 SLBEJ @ 4Ghz + EK Supreme Acetal + Laing 10w + Feser 240 / MOBO Asus Rampage II Gene / MEMORY 3*2Gb Transcend DDR3 1333Mhz @ 1600Mhz 8-8-8-24 / GPU ATI HD5850 1Gb DDR5 + EK-VGA Supreme Acetal / PSU Corsair TX-750 / HDD 150GB WD Velociraptor(Boot) + 500GB Seagate 7200.11 + WD 400GB(storage) / MONITOR Samsung SyncMaster 2223NW
I hope
it seems that the Hx is too big.
the high side pressure is low and the low side pressure is high?
i have tried first to shorten high side, then i added to low side and not much.
best so far is -47c load and -68c noload.
Very nice Kayl, I like it
how much captube you`ve got ?
