Cascade 5 (2 Stage GPU)

[Pete]

Yes he can braze and build. But that doesn't polish the tubing

OMG can't belive you of all people just said, LMFAO. I use to be a frame builder so i know the low down on brazing.

I do agree scotchbright has been used which is not a problem at all. It's a cleaning aid after all!

Be cool if the unit could run raw! See the naked tubes then

[LittleDevil]

Really nice unit my friend and really clean brazing

Haven't You Guys thought, that 1.1 kW condensor will be too small to cope with load from rotary + load from 2 heavy-loaded evaps ?

I'm little worried that can be too weak .

I know that Pete. It just shows me the attention to detail that's used. You would agree then that there is a big difference between prepping the joint and prepping the entire run.

Its dual evap? I didnt see that anywhere...
Plus with proper second stage desuperheating it will be dealing with much less load.

hi piotres you may be correct and i will now be fitting a bigger compressor to the first stage as well

Btu/hr : 21800/22000 LG NP642P

But remember this unit is for experiments in cascade build and will have many different setup

When this comp goes in I will be trying out a water cooled DSH coil as well
Just to see how well it performs

Care full now bazx! You will become addicted to the water cooling of phase systems! It is just as good and addictive as water cooling the PC !

Yeah i do agree, but Bazx has OCD on and build he does for it being 100% perfect! I can't fault him!

WC'd DSHC . . .how that work i aint seen nor heard it before!

I know the feeling

its just like a coiled HX only instead of using a compressor to cool the HX
i will use a water loop

it will go just after the compressor but before the condenser on the 1st stage


the idea is to remove some of the heat before it gets to the condenser

just like a regular DSH only i hope to be able to remove a little more heat

if it works i intend to try doing away with the condenser altogether and use a plate hx on the first stage

but we will see

Interesting concept but I suspect it'd be bulky as you'd have to essentially add another loop into the system. The thought of adding another point of failure to a cascade doesn't sound pleasant either.

So will that be a like a COIL IN A COIL HX but a CC DSH? Water passing on the outer coil with the DSH directly in the center?

What rad and pump?

Thermochill PA120.3 x 2, DDC ? I got a few bit of WC kit if you haven't any there at present! Only known you to have phase of varying styles and what Thicky has shown me too

this is verry verry old technology concept, It is all so called heat reclaim, machanical subcooler and so on, slight differance between some but all the same idea

[bazx]

it may be old tec but i am finding myself drawn toward it

and i will not be happy unless i have run a few tests

here are 2x of the suction lines i have had made up for this cascade

same line i used in my other units 1m long with 50mm of 10mm dia each end

yes coil in coil

i already have the parts for the water loop nothing special but will do for this
experiment

Don't take that the wrong way, it was meant for others, it is very good system, like I said be care full, other wise you'll find your self addicted!

Ever since working on my first water cooled plant I fell in love with the system!

I plan to make an all water cooled cascade my self in the remote future!

hehe i did not take it the wrong way i also read your earlier post

and you are right i have already found many places and way to add water cooling

and it may well turn into an addiction

[Pete]

Ooo build a water chilled as well, cool it more!

[bazx]

the evap i am using for the single gpu setup will be a chilly type from cold ice but with an extra turn on its length

the suction return will be fitted at 90 degrees to the evap

the hole con fig will be the same as the that used in previous cascades

with 3x holes drilled at the base into the suction return

You like that evap and mod a lot don;t ya!

[piotres]

That pipes are too shiny . That's just overkill .

Congrats .

[PPInDaHouse]

amazing work bazx! very clean

[bazx]

got the valve assembly mounted today
