Hello,

my first refrigeration system is ready.

I let the pictures speak.

The complete data and equipment features will follow. I currently have little time. (Yes, it's a CryoStar SingleStage CPU evaporator)

First class cooler :up: It looks like you've been building for years.:clap:

BTW - I love the load tester :)

Hello,

my first refrigeration system is ready.

I let the pictures speak.

Real nice tidy looking unit.

There is one small thing letting such a tidy unit down for me & thats the nasty gaffer/carpet tape, why not use some large shrink sleeve.

Nice unit but not even a hint of frost on the load tester meaning huge delta between evap face and evap. Using any tim and have good contact?

Very nice lookin unit and wiring.

Really nice and clean i like it. What evap is that?

Really nice and clean i like it. What evap is that?

he said he has a cryostar evap
Pete

he said he has a cryostar evap

Sorry i missed that and it was dead clear (admitly i just wnated to look at the amazing unit) Sorry, slaps my wrist.

yeah it is a really amazing unit, -60c on your first try, that's pretty AMAZING. I would like to know how much of a difference the evap makes over say a kayl block, plus what the charge is

no ice on loadtester...

very good looking unit well done

can you tell me where the K type temp prob is fixed to the evap

thanks baz

Very clean build. I am impressed. It's tons better than some that I have seen that actually sells unit around.
As for load tester/ice/etc.... it always seems different among people. Someone's 250w turned out around 180w on my load tester. Regardless of load actually subjected, that is quite nice temp.

If the electrical stuff was tidied a small bit, I'd go so far as to say it's the cleanest unit I've ever seen!

I was calling his glass of Coca-cola a load tester. :up:

moc:
no ice on loadtester, I don't have totally iced loadtester that looks like those either when testing nl11f units. I don't know why but it seems to be that way.

the heat goes to cold and thats proberbly why, I can run my loadtester 4-5H without getting ice all arround the loadtesters, but the 10mm thick copperplate the resistors is mounted in is always freezed as well as ~half of the resistors. when I run bigger units such as rotaries I get fulle freezed resistors. I wouldn't put to much attention to this, better just insulate the loadtester and you know the heat won't "run" away.


btw about the drink, it doesn't look like coke, I think it's whisky.

My load tester gets frozen all the way through on my NF11FX builds down to about 225w in which the backside, through all the insulation, starts to noticeably warm up. The point over all this was a -42C evap temp, 180w load, and not a hint of ice :)

Hi,

thank you for your comments!

It's a CryoStar SingleStage CPU evaporator as in the first post I said. Unit is filled with R507. bazx, the probe is on the surface of the evaporator and will be assembled by the pliers. The contact is good. The resistors and the evaporator were connected with silicone paste.

btw about the drink, it doesn't look like coke, I think it's whisky.
Absolutely correct. :)

The copper block is too thick that's why :)
Also insulate the resistor (after putting thermal cut out) so no heat escapes but through evap and you will see why.
Duh

lovely unit

is there a particular reason to choose sunon?

@DagoDuck: You need to make copper load tester (15mm thickness or more) with cartrige heater, now you tuned that SS for 180W and you got great temps, but unfortunately you don't know what will unit ''say'' if you test it with 200W load or more. I have a lot of experience with that, i try to tune unit for lets say about 180W and when i try with 200W or more heat, unit has totaly crashed, it doesn't even hold -30°c at 200W. If you want to tune unit for really high load it is strongly recomended to use suction accumulator, it helps alot!

What were your pressures at that load?
DagoDuck
12-19-2007, 04:09 AM
Yes, this I have also considered, LD. Thank you for your advice! :) By the next unit I will change the load tester!

Thanks, Tony!

2long4u, I believe I have forgotten this. This are pressures without load on unit. http://www.fmkonzept.de/images/refrigerant/NL11F/IMG_2052.JPG With load it's around 15 Bar HD -0,1 Bar ND at 21°C room temperature.
