Fun Little Cascade Project [56K Will Commit Suicide]

[NoL]

Not a normal start, nor a normal setup, but I think you'll like watching the progression, I know I like to

So you might be able to guess whats going on, and what goes where, and what is what, if you have any questinos why not ask. The first half, or pictures basically of tonights stuff, could comprise a very good chiller, but instead is the first half of the cascade, and this could easily be a start for a great single stage, all about how you approach it

And into the pics of todays progress.

The Base!

Opening the damn thing.

Ooo nice packing, (Note to self: Save this!)

Who needs this crap anyway? :rofl:

Nice plug! Keeping that as well!

Now that's a sweet image right there! 5000Btuh rated condenser with fan!

Nice side grills, where air is drawn in.

Nice front with filter and overall look.

Lets break this thing open! And definitly keeping that top and front, has a nice filter as you can see. Easy to get into with those nice screws too!

Time to rip out this crap.

Nice evap, too bad!

QS072CCA. Tasty, this things tall still unlike Rechi's, however thin!

Removing more pieces.

And look at this nice spot for a controller!

But who really wants this crap?

Captain Cascade beware! No filter but its definitly angled upwards! *GASP!* (just joshing mate, you know your right)

Now to get into that Evap box.....

Off with its head!

And off with the recirculator! Its really a blower fan of sorts, sucks air through the Evap and throws it left and right.

And out with the Evap box foam...

And bend that evap out of the way.

Uh oh! A nubbly!

I got a solution for that.

Ya know what they say. Location location location. This was the quick planning stage. Then some piping.

I'd eat this stuff if I could.

Just a shot of the room and parts.

Look at that, easy as pie. Throw some 3/16 up, down into a nice filter. Hey look its pointing down!

And thats it for tonight! First stage brazed, and now pressure testing!!

 

[Pjalchemist]

Dam Nol you get all the fun. I swear one day i will get a unit off you thats rated 240v just to experince the NOL effect. This going to be a beast. Home Depo must love you! Keep up the work, bloody impressive!

 

[Ham]

Looking good as ever mate. Keep up the good work

 

[NoL]

Changing the oil in the roto, boy is this a pain in the arse. Gotta sit there for an hour or two and jiggle the damn thing.

And here's the nice looking lineset. Maybe it's not 4ft, might be 5ft, who knows, its long, he'll like it

Chilly1 style modified evap at the end, hot gas bypass line and refrigerant line can be seen. Braid will be going over once she's all done and brazed up and insulated.

 

[NoL]

Now I can explain why this looks like a teenage drinking party.

Okay so odd system but it works!

Now the rotary contains 180cc of oil from the factory.

I'm not good with holding up my hands and telling you how much is there, and I don't know anyone who is. I also don't want to dirty up the cooking ware. Thus the following system.

Oil out of rotary goes in a plastic party cup, who knows what size that is.

180cc is 3/4 of a cup basically. Therefore, pour 3/4 of a cup of water into ANOTHER IDENTICAL party cup.

Compare height of liquids.

Realize I've got about the exact same, of course, less of the oil but only a mm or two less.

Jump and shout, run a few victory laps.

Now, taking ANOTHER IDENTICAL party cup, pour in XXX height of Zerol 150, as shown, to th e same height as the oil cup. Woohoo. Now I know most of the oils out, and I have about the same amount to put in...

One problem....

*view last picture*

 

[Silentsnake]

lol i like the last pic rofl!

Im gnna sound like a big n00b now but, what the hell are you making lol!?... is it like a phase kinda thingy lol :wavey:

 

[adrienspawn]

Heya NoL! This thread is deja-vu, I wonder why

 

[NoL]

Its a very low temp phase unit, called a Cascade by most.

Here's an update, or well pics of the update, and expect more later

Got my funnel, but wait, it's too big!

Time for.... ELECTRICAL TAPE!

Temp wiring and such, and well, sorta replugged, new oil inside.

 

[Pseudonym]

So why did you fill a cup with water? I get that you are comparing heights to work out the amount of oil needed, but couldn't you just use two cups?

I guess i'm missing a vital point because you clearly know what you are doing, your projects always look sweet.

 

[NoL]

Okay, the manufacture said it HAD 180cc of oil in it. Now I got out all the oil I can, can't get it all out, so I poured 180cc of water into a cup next to what I had to see how close I was

And onto final pics before the long time stuff.

Piping piping *whistle away*

HPCO and a Solenoid for Hot gas bypassin

ZOMG Braze!

Now ain't that just tight nit

MMmmmm captube, not easy to wrap that by the way.

 

[Mr. Smith]

Awesome. What temps will you be getting -80/250w proccy?

Is this one for you? Enjoying the log

 

[NoL]

-60C to -80C is the goal, it's really not that powerful a unit compared to what some guys do to hit -100C (I have two 1/2hp compressors, and ones actually smaller then that, some people use more then two 1.5hp compressors).

OMG! -60 this is gnna be interesting i've never actually seen anything like this lol

 

[NoL]

Oh -60C will be the warm side

Updates! Ice ice baby! Adding plenty of refrigerant, going to put the precharge up towards 5-8psi unloaded as a goal with full insulation. Then start to the second. Pure r290 at the moment in the charge, nice low pressures, and guess what? This thing is incredibly quiet. The roto makes very little noise, and the fan has two settings, quiet with lots of air flow, or loud with enough airflow to move tools

So here's some ice ice baby.

 

[Silentsnake]

Why is it always dark when you are working lol any chance of a pic of your work area like the log btw

[NoL]

Dark? Does it seem dark? Ive got a big light above me, I'd think there is enough light... Maybe not the brightest light, but it works ya know.

 

[NoL]

Update!

No ice yet, still vaccing the crap out of this.

But, controller arrived, another rotary for possibly a different project, two mounts (BIG THANKS TO BLUEAQUA!), and a secret item.

Controller is a simple PID, with output to relay or SSR, and allows a temp to be set to trigger the first stage, through a contactor that's also on it's way.

The PID nicely enough reads every kind of thermocouple you can image.

A can of coke isn't that secret
