Blue and naked ...and rest You should know LOL ;)

Hello

Mine next cascade, it's very simillar for this one : http://www.xtremesystems.org/forums/...d.php?t=198072 , but this one will be having automatic oilseparator and blue baseplate :D .

Specs :

compressors: Sanyo remark C-RN110H5A around 13000 BTU so 1HP on both stages
evap: steeper
XVes: Alco TI-HW+ nozzle 01 / captube 0.9 mm
HX: plate HX , 12 plates
condenser: 3.0 Kw, alu-cu, cooled by 300mm/230V fan plus alu-cu 0.4kW 1x120mm desuperheater for 2nd stage
refrigerants : R507/R1150
oilseparator : Shineyear automatic
safety : Danfoss KP7 cut-off, 1.5 litre FACH expansion tank
case : baseplate with welded frame 70 x 50 cm , blue painted+ wheels
others: Anaconda shocks absorber on 1st stage's suction line ,2 gauges on both stages hi-sides.

There is already much work done than only frame welding, but I don't have digi cam to take some shoots :( (mine parents take it on holidays) ...

Wheels and paint which I've already used :) .

I've already paint baseplate, mount wheels, braze and polish evaporator,screw some parts to baseplate ...now I'm waiting for orifice for TXV and expansion tank :).

I decided now to apply ...clear coating on pipes :D. Yes, IMO natural cooper color links very well with blue :). So I want to make it more lasting :).

Today that was on 260W after 30 minutes of test :).

http://www.members.lycos.co.uk/piotr...de_blue/31.jpg

And 1st stage compressor temperature after 1.5h of cascade work . Not such hot as for rotaries :).

Now I plan to swap motor fan on condensor - this one is heating too much :(.

Best Regards,
Peter

wow nice... great idea with clear coat :)

if your load temps were 99.9c... i bet you would double check thermo, add more insulation, et cetera LOL!

edit- your using the receiver as a receiver not epansion tank correct? do you not need any more volume on low side?

he's using receiver as exp tank here teyber...

look also at this pic, he brazed shut the receiver outlet
http://www.members.lycos.co.uk/piotr...de_blue/21.jpg

and this one also as the receiver inlet is connected to 2nd stage suction line with captube

OMG some one make Peter stop posting these pictures, hes killing me !!! :rofl:

:rofl: That's Funny ,even if it was correct.:ROTF: Accumulators are on the low side. :p: Receivers usually hold liquid on the high side before a TEV.;)

That expansion tank put like that it has a nice potential to trap oil. There is refrigerant flow going in each time you stop the unit. What do you think?

man I need a cascade

I don't think that is oil trap. Yes refrigerant goes there but when compressor is not working so oil isn't "pumped" there, + we have oilsep on 2nd stage :).

Thanks for nice words . :) sure I use receiver as a expansion tank . I've found that receiver before TXV even make temperatures on 1st stage worse (maybe not worse but for sure not better, same about discharge pressure) .

i was asking as i saw 1 receiver... i never brought up accumulators, i know what receivers are but he in the past has modded them for expansion tanks and i was wondering if he either didn't have expansion tank or didn't have receiver for tev:rolleyes:

Hello

Fresh portion of photos :)

http://www.members.lycos.co.uk/piotr...de_blue/32.jpg

Unloaded with final charge :).

http://www.members.lycos.co.uk/piotr...de_blue/33.jpg

Pressures idle. That 5 bara in which condense R1150 if funny I think :O . I've never seen such low discharge on 2nd stage in mine cascades. I think that's thanks to ... :

http://www.members.lycos.co.uk/piotr...de_blue/34.jpg

1st stage goes very low in idle (when 2nd stage is running without load) :eek:.

http://www.members.lycos.co.uk/piotr...de_blue/35.jpg

http://www.members.lycos.co.uk/piotr...de_blue/36.jpg

Pressures and temperature on 260W after 1hour test :) ...I know, I know ...last cascade has been making -100.4C on that load but it has another oilsep and Kprobes are different :p: . This one is making -98-100C at 260W .

http://www.members.lycos.co.uk/piotr...de_blue/37.jpg

1st stage loaded .

Now cascade needs only final test :) .

Hello

I was holding this unit in home for a long time just for pressure test - I've seen very slowly pressure drops (sth like minus 0.2 bara static less every 5 days) on 2nd stage. Like always I've checked all conection/brazed points. All fine . Finally I've check also captubes - and yes - bingo :eek:. I've leak on staraight thick captube piece going to cut-off :eek: :eek: . Visually all was fine but "Gas control" from Wigam and another tested show small leak :eek: :. Now I know that captubes, specially those thick ones are worth to be checked :mad:.

http://www.members.lycos.co.uk/piotr...de_blue/42.jpg

http://www.members.lycos.co.uk/piotr...de_blue/43.jpg

Spray which show bubbles :up:.

http://www.members.lycos.co.uk/piotr...de_blue/44.jpg

Cut-off and new captube part, this time in good test after mounting :cool:. 25 bara inside.

http://www.members.lycos.co.uk/piotr...de_blue/45.jpg

After recharge with fresh ethylene cascade show -115 :p:.

http://www.members.lycos.co.uk/piotr...de_blue/46.jpg

and 1st stage goes LOW :eek: with final charge :clap:. No load.

http://www.members.lycos.co.uk/piotr...de_blue/50.jpg

2nd stage unloaded with final charge.

Sorry sth was wrong with mine camera that time when cascade was 100%ready :mad: :mad:.

lol be sure to have a drilling machine charged and ready to go when the unit arrives.

@piotres ..your the man !! great looking unit once again :up:

Great work Peter :up:

Some news....when i received it 2/3 months ago , the 1st stage's compressor was dead...
Piotres send me a new compressor , and i fix it with someone in my town ( 180€ to do it )
( if i want to send it to piotres , and piotres send it to me after , it cost 300€ .... )

Now it working :) , i'm just disappointed by this problem...

Some result :

Biostar Tpower i45
E8600 ( Ex-Pt1t )
2GB Crucial PC8500
PCP 750w

I'm disapointed same as You :shakes:. First time for me rotary compressor just die during transport :eek:.

Many thanks people :)
