Off The Hook. They even look like they know what's going on.

Aww nice one Kayl, thanks for showing us that!

Dibs on the brunet!!

uhm, nice gigabyte girls
are they provided in the bundle ?

[kayl]

thanxs guys, i though you might like those pic

[PhilippF]

Nice motherboard^^

[Raja@ASUS]

nice work kayl as alway

i could do with a little help my self

Couldn't we all Baz, I wonder how it would affect temps though, both at idle and load?

Hey kayl,nice build,great results and awesome pics.You lucky,lucky dog.

[HoriWanderFuLL]

did i here someone quote BonerSmile ehehehe those girls Phew

I have a new found love for Gigabyte now.
Well done with the WR oc kayl. I'm also surprised you could actually concentrate with such gorgeous booth babes there to keep you company.

As K404 said, i also want to know if they were actually interested or were they just there as eye candy?
Pass the brunette this way when your done with her Pete.

I received some new 1.7hp compressors the other day and are planning a new cascade. r507/1150 I expect some really nice load temps with the new kayl block




Compressor compared to a 1.25L soft drink bottle, these compressors are massive



Unit parts placement



The new kayl block as the evaporator, its a good 20g heavier than the last head, same size just liquid levels smaller and plates tad thicker to ensure refrigerant has good contact with copper plates for maximum heat transfer. I have change from a 3mm base to 4mm to help with at xtreme vocores and oc's

[Unseen]

Kayl i am waiting for your new project

Good luck!!!

Kayl i am waiting for your new project

Good luck!!!

thanxs unseen, i got a small start to the unit tonight.
DId the out line of the pipe work see what goes where.
Pressure tested the HPCO to make sure no leaks before installing
Also insulated the plate HX ready to braze in.

[before]

Looks nice

[kayl]

Looks nice

thanxs before.


Brazed system together tonight, and pulled a vacum each stage for leak testing.

Love the sleeving

[n00b 0f l337]

Nice system Kayl! Good oil sep to, how much precharge that monster take?

[Unseen]

woww! Nice sleeve!!! Bro i see you are using two capillaries too... Tell me your high pressure.

[tim-]

dual capillary is nice, as well as the sleeving

wondering how dual capillary works on evap, anyone who have tried?


regards
Tim

Thanxs guys im glad you like the sleeving, its funny I have had this sleeving for over 2 years now and this is the first time I have used it on a unit?

Nice system Kayl! Good oil sep to, how much precharge that monster take?

Im not sure nol, all I know is Its got almost enough volume to not need a expansion chamber.

woww! Nice sleeve!!! Bro i see you are using two capillaries too... Tell me your high pressure.

I have always wanted to try dual capillary line feeds Unseen.
With normal cascades I wanted to go shorter than 1.8m of capillary line on the first stage but still have enough resistance to ensure the refrigerant condenses properly. So dual feeds should do the trick, but never really had time to experiment. But after seeing you use it a while back though id give it a try on my next unit.
I imagine that your first stages discharge pressure is a little lower than normal with dual feeds??

[n00b 0f l337]

You didnt have to add any oil to that oil sep?

[tim-]

kayl:
I'm not unseen but I've been dealing quite alot with dual captube and I can say, you're right, the discharge pressure is slightly lower with dual cap compare to single, if thats good or not I don't know but the results is good and massflow as well.

[n00b 0f l337]

The question there is I just think your less restrictive. You could acheive the same thing with a shorter captube, but it would have to be quite shorter. A bad analysis of this might be, if your captube length would normally hold X watts, then two will hold 2X watts. In a sense we're doing the same thing as having dual evaporators, but only with one, and so we're creating double (give or take) the headroom.
It is great though! If our actual evaporators were bigger I'd try dual captube to it, but I think a larger diameter line or simply a shorter line can take care of that.

[jinu117]

One thing that I realized looking at it is... if the impact of dual cap tube actually is happening in more practical level than say, on equation level. While restriction as whole might be same, I am wondering if dual captube actually alleviates some resistance caused by oil flowing in circuit... It really shouldn't impact it too much but I am just wondering Lower discharge is usually good thing as long as you have enough to condense in different conditions through cap tubing designated

[n00b 0f l337]

Plus if condensing pressures a large problem a fan control could be installed in some situations.

[kayl]

You didnt have to add any oil to that oil sep?

Yeah 400ml, I only added 300ml, I was even considering not adding any at oil, since there should be more than enough in the compressor. Mainly because the system this compressor would normally be installed in is so much bigger than the system I have it running in. What ya think Nol?

Hey tim, that’s cool, I guess ya been playing dual cap lines with chillers maybe with some insider information?
Lower pressure istn so bad as long as the pressure is enough to condense the refrigerant at its liquid line temp. Ie I have seen 150psi when using r290 with cascades with a big condenser and a cold liquid line even at load But then in a 42c warm case that pressure rises to 200psi running for several hours at a time.

I think of dual caplines as a bigger ID capillary line. My main goal is to deliver more liquid refrigerant to the HX and run a lower first stage Low side pressure with colder temps. With my last cascade I had the second stages liquid line leaving the HX at -35c feeding the cpu head.
I charged the cascade so first turn on 1st stage was down to temp in 3mins and second stage at -100c 2 mins later. So first stage doesn run that cold, but has lots of capacity and is flooded well. Result it only takes the cascade 5mins for total pull down to -100c. Havnt seen another cascade pull down that fast yet

Im not really shore what will happen, but I imagine the lower discharge is as a result of less refrigerant backing up in the condenser. As you said though I hope the refrigerant condenses properly, time will tell.
