me too. What is the pemperature of the HX ?
Did you tested without load ?

awesome job, very clean

do you think the condensation will tear up the box at the in/out holes?

this was my first time using a tev and i can tell now i wont be going back to cap tube:D

the temps were balanced at -32 in and -30 out under load with the unit running for 4 hours

i had run out of 402a so used what i had 404a but this is still early days for me so there will be changes

That is great dude very clean. I think on the list at the top you have your compressors reversed.

This looks like silver brazing rods...

bazx, I would stick to the R404a, I don't know how the R402a will work with the TEV, as its designed for R404a/R507.

Looks and performs really good :toast:

BTW why You have used brand new SC18B, not SC18CL :D ?

Now that's some really nice work :)

Need to get the rest of the insulation done ;) and that'll just make it work even better than it does now, though it's certainly doing the job, and really looks good.

I'm well impressed Baz!

I can't wait to see the next revision of cascade now :D

Cheers

thanks gray i have already ordered a plated hx from cold-ice i need to make a unit small enough to fit in a nice box

Excellent work, but.............. Dont you just hate those dramatic Buts:eek: The suction connection on the compressor on the HX box needs a loop of copper inbetween the compressor and the hx connection. Otherwise the compressor will shake those brazed joints until they fail:(

I try and think about every thing but... I manage to miss something
i should have it covered by cascade 3:D

bazx very very nice cascade! :up:

what are your static, high/low pressures on the 1st/2nd stages?
07-06-2006, 02:55 AM

Where did you place the sensing bulb for your TEV? Is it inside the HX box?

i placed it right at the top of the coiled hx where 2stage gas comes in

1st 7 bar static

with second it is harder to say as it will change depending on unit temp

static pressure on the 2nd stage at room temperature

what is the diameter/length of the captube?

thanks for the answers

i will be working on the unit later and will post up the pressures:)

i am changing the hx gas today for 507 so will add that too

Changed the hx gas now for 507 with some good results hx temp dropped

To almost -50 at times but averaged out around -45 which was way better then i expected

I will try 402a see how that come up

in the pic below the the -41 is the in feed to the hx and the -48 is the suction return end

Also been working on better way to make up suction return lines

This is the first prototype i had it made with the ends all welded together
To form one piece it is 1m long and rated to 2000 psi by the company that made it

yes got the hx plate now, 12 plate also found a good enclosure to fit one of your evaps

http://www.xtremesystems.org/forums/...d.php?t=110459

i want to put the plate in a box with the tev like the one i built for this one but much smaller

but before i scrap this cascade to build the smaller one i want to try out
the new enclosure out

What's the function of the receiver on the 1st stage? It works like a capacitors in electrical circuit stabilizing the gas' flux?

Sorry for my bad english...

P.S. Beautiful work :D

the wood is mdf which is very flat and comes in many differant thickness

in this unit the hx box was made from 12mm or 1/2 cut to size on a chop saw
then glued and nailed except for the lid/top which is screwed on

MDF for the win :)
One of cheaper wood, very heavy, awesome vibration dampner, cracks bit easy with shock so have to be careful, works awesome with wood glue, darned easy to cut cleanly. They use it a lot for professional speaker enclosure due to sound absorbing and vibration absorbing characteristics :)
Looking very nice Bazx :) Is this going under your awesome looking test bench setup you showed while back? :)

Heh I have a semi-similar wood, called hardyboard.

hi jin and nol

i used a brad gun to fire in 1 inch brads like a small pin

i am unsure what hardyboard is to be honest nol i have a feeling mdf has been band in the US due to the dust

i have a LD cascade case on the way and will be putting cascade 3 together soon and hopefully that will fit on my oc bench

nice nail... MDF can creak up so easily with screws that I always use glue for it :) Works awesome... had really hard time destroying custom case I made while back out of MDF and wood glue... it just won't come out so I had to use demolition hammer basically.

once glued it is very strong

the trick with screws is to always pre drill the hole for the screw

clearence for the top and a tap size for the screw
