Hi

Some weeks ago Myrddin669 (a guy from tweak.pl forum) ask me about a SS. So let's go ...finally I put Danfoss NL11F and CPEV Fach.

Specs :

Compressor: Danfoss NL11F
evap: chilly1 patern (made in Poland )
holddown: PCV 10mm
XV: CPEV Fach "PZ"
condenser: 24x24 cm, 2 row, alu-cu, 6 pcs Artic Pro Fan TC 80 mm (moded @ full speed of work)
Refrigerant : R507
Case : Chipboard, 30x35 cm, painted orange (special mix by piotres )
others: Low side gauge, SLHX






























































Now I'm waiting for suction sleeve and new drier .


Regards
piotres

Very nice job!! I like it - how is the cpev working?

[piotres]

It works fine ...Just put the refrigerant till the valve isn't hissing at all - then Yoo can tune the sucton pressure between eg. -0.8 bar to 1.0 bar or more . Nice toy .
But somethimes there are problems with POE oil and CPEV ..it just freeze and the tunning won't work ..so I must change the filter . I have second unit with mineral oil and same CPEV - all works fine.

PS. Of course the paper tapes, are just a secure for paint in building time

Have got to love it (in some very insane way) It's a very fine unit, thought I would have prefered another color - It hurts my eyes to look at it

What are the temp loaded and unloaded??

[piotres]

I must change the filter and put a new R507 portion - should be -40 to -45*c load

nICE and clean job but i think u start search for some smaller condesors [120X120 or lilte biger ]

[SustaiN]

WOW Piotres! Again u amaze me with your awesome work! I love the color and it looks very clean, neat 'n' nice! Keep up tha good work bro! This is definitely one of the best-looking SS I've ever seen

yes

@star882 : yes I haven't purged the SLHX when I have brazed it ...the pipe inside sure have some oxides but only in some cm ..maybe 5 cm . So it won't be a problem for sure .

@SustaiN : THX

both your filter and condenser are huge...
using twice smaller condenser you wouldnt loose anything but a start up time would be less

hehe I really want to have a smaller condensers ..but in Poland now I can't get anything smaller

[\Karting_freak]

that sucks...
how about using a smaller filter?

[star882]

A larger condenser (within reason) can't hurt, and it can provide more cooling. With all the fans, you also get redundancy; if one fan fails, it will still work.

The desuperheater is definately extra, although it'll make a good vibration damper.

Big filter in units with CPEV and POE is necessity .

this WONT help. half a degree means nothing actually but start up time rises a lot )

tnks didnt know that... i'm now building a rig with cpev so your advice is helpful )))

[piotres]

Hi

A little sample :





Pure R507, CPEV closed completelly

Whats your low side pressure at 70.9 ??????

[piotres]

I haven't measured it

[Waus-mod]

What will the load be estimated?

[4everCS]

Looks like a great system!! Why dont you guys use better filter dryers?? Like a parker or a Sporlan... They work 100 times better than a spun copper one. The spun copper ones only have a screen, sometimes a little bit of silica gel....

[Jort]

every commercial freezer has one of those, its no use to have a bigger one with this system.

Nice work. The orange makes a loud change to all the jet black units people make!
