I make one stronger unit on request for one guy. Here are some pics of the unit: Compressor is Electrolux MP14FB 1/2HP and r402a gas.

very clean

do they make a condenser like that but larger in size??

I like it, but why are you painting the stems of the schraeders?

Actually I think that looks good with the stems painted :)

Do you use any kind of accumulator?

I just wonder as it seems like it may have liquid return issues when fully charged for higher loads. That is if you're charging and testing at higher (200 to 210w) loads.

It's just that the suction run is fairly short, and the captube exits long before the U-bend.

Cheers

i think the builder takes pride in his units..attention to detail rules..
it's a bit like a fine italian hand made suit or a one off special built car.. little details make some feel good.

looks really clean and err... nice :)

any difference on temps compared to nl11f?

Forget the size of the compressor, the size of that condensor is awefully small for a 1/2hp (6000btu) comp. Standard condensor size for a 1/2hp system is about 3 times larger than the one hes using and im not talking about physical size but in the # of fins and length of tubing.

Have you taken a head pressure reading yet?

The condensor seems well specced for that compressor. 3 times the size???

As for the MP14FB compressor, its very good indeed although I did not find a very big gain over NL11F atall using straigth R402a. I did however find the extra capacity comes in handy when playing with higher pressure stuff. In General R404a/R507a compressors is not perfectly suited for our application, the motors tend to be overpowered for the displacement generating alot of unnecesary heat. The GP14 R134a compressor will yield a better result.

What is load results in comparison to your NL11F systems? I found very small improvement if any?

You need to fit heat load from the proc plus 30% usually for size the condensor, what you are saying is because you are looking at some condensing units that comes ready for AC or comercial use, where you are looking for a lot more BTU's than we use in our application.

I don't understand what ur gauges are reading over here in Nova Scotia we use Psi. Can you convert? Math isn't one of my strong points.
Gray Mole

It's on the gauges. 1 MPa = 145psi

So it's 1.25 MPa, that's around 181psi.

Is that idle, load, if so what load?

Cheers

No big difference, on 1/2Hp mybe 2,3c better temps on load...

i believe it s the HP gauge

1.25 Mpa => 12.5 bar

Now when some dudes Question the performance, Do you have some numbers for Us?

Wattage or temps and so ? :D

Is the compressor louder than a NL11F?

MP14FB is louder than a nl11f yes..

Im interrested in some performance numbers too as I found not much performnace increase atall in comparison with nl11f using pure R402a

great job ! very clean ! :toast:

do u get 100% condensation free isolation ? how ?

Yes no problem with issuation, do you have any problems with your SS?:)

noise? any readings or subjective evaluations ?
