I'm wondering if would work putting an HX between condensor and filter/drier, feeded by the succion line?

Something like to cold the gas in the condensor outter and filter/drier inner with the cold that we have in the succion line, next to flexivible betwen the compressor.

I should call a pre-subcooling.

Will this afect filter drier?

That's a SLHX.

No problem using it in a Single DD?
Will this perform better?

BTW: I saw another day, not much time, thread with a nice HX?, SLHX? homemade, it was very nice, and i would like to se it again, but i can´t find it :(

People use em in SS and Chillers quite a lot. It does help performance.

and it seems to help the COP nicely on most systems

There are a lot of threads where you can see a unit with a nice HX! :D
And most of them are homemade! ;)
So ... a lil bit more infos would be nice! ;)

n00b 0f l337: not that one, but quite nice :)

404Power: it's recent thread, but i can´t find it, i saw it something like two days ago, the SLHX was upper the compressor, it has elbows on sides.

May the cap length change then the usual, if we use SLHX?
Is it better use SLHX before or next filter/drier?

You should put SLHX after filter/drier :) I heard that in subzero temp filters/driers are not working properly

For example here you have photo of my homemade (very simple) SLHX:

Is this the one (http://www.xtremesystems.org/forums/showthread.php?t=88368) you were looking for?

I don't know if it helps. It does cause additional load on the system, which usually isn't a good thing.

I usualy use 2,85m of 0.031 (0,8mm) for R404a, may this change with SLHX?

I would leave it that way and go for it! :D
If cap is too long ... cut it! ;)

I love these threads.

New User: Hey guys I have and idea. What if you compress the gass and cool it so it becomes liquid then drop the pressure and let it boil and put the evaporation point on the cpu and get crazy l33t temperatures!! Would that work?

Senior Member: .... yes, whats what the world has been doing for the last 100 years, and we here on computers for the last 5. Its called refrigeration.

No bashing intended just poking fun :)

Neither your words answer to my question. I call this spam, and i think it's worst than don´t know what's an SLHX.
I'm not english, so it's normal i don´t understand all tecniques explained here, my english isn´t the best you see arround here
Most of the times i have to see pics to understand the circuit, and if i don´t understand it by the pics sometimes my english don´t help me reading your text´s.

No!? :stick:

And as you can see, my inicial ideia seems like don´t work, because i was thinking to put SLHX before filter/drier, and looks like LukeXE said filter/driers are not working properly unde subzero temps.
Looks like my question wasn´t such a dumb question.

I made a SLHX for my 3/4hp SC21 SS and I used 1/2 pipe with 3/16 wrapped round. Worked very well wiith R402a R410a blend.

I placed mine after the drier for the same issues described by Luke.

sl4ck, no worries! epion2985 never meant it that harsh.

And a something like a HX before the filter/drier has been done before aswell.

http://www.refrigeration-engineer.com/forums/showthread.php?t=4365 < Read this. The discution on sub cooling starts on page three and goes on very detailed and great info (This is why I like forums dedicated to real working refrigeration :D get lots more fundimental info)

I'm using a SLHX (comercial HX) in my VapoLS full conversion (nl11f, new condenser, new dual evaps, new drier...) but will try it with cap tube instead CPEV's (I need them to the autoc and the cascade).
I don't know how it will perform, but will try it if I have space inside VapoLS case ;)
I'll let you know (and all the community) how it goes. Keep tunned.

Relax, no need to get your blood pressure up, we are all friends here :)

Sorry I missed your question about placement.

Hi!

Yes, allready began working on it and seems that there's no space to place the SLHX in there and insulate it... at least the comercial one (a litle parker I have).
Don't know if will use one in this system... sorry m8 :(

Regards!

what tube do you use for the SLHX in a single DD?

1/2" ?

I like 1/4" thru 7/16".

Almost always I've used 1/2' with 1/4' inside, works really nice :)

You can try also 1/2' with 2 or 3 1/8' tubes inside (or 2.3 mm captubes) .
