Now here is my other concurrent project (along side Pegasus, which is its planning phase). This project is a completley different project, focusing around a water-chilling system converted from a regular old 90buck 5250 BTU unit Air Conditioning unit from Kenmore. The purpose of this computer will be to run folding ~_~ or at least that's the plan ;-) though i'm considering making it into a gaming machine...seems a bit overkill for that lol. SO folding it is!




Say hello to my little friend...this baby is about to get ripped to shreads for the good fo humanity *ahem*

The actual Construction begins with destruction here are the step by step pics of it happening last night enjoy the carnage




I begin by unscrewing the screws..some come out pretty easily like this one on the top (which had the pleasure of being the first screw).



The difficulties BEGAN with this screw..that took quite a lot of effort to get off, of course i was too lazy to get the drill, so i trudged it out..eventualy



Removing the filter out of the front just so i don't have it fall on anything, it was a loit tinyer then i thought it would be, considering some experiences i've had with past AC systems.



The back of the unit (where the heat dissipation takes place) was a much bigger pain. ALl the screws came out with a lot of effort...well almost all that is.... Save for the top left one, which I had worn so much from attempts that it was beyond any screwdriver/drill. So what's a man to do with it?...well



Take a dremel to it of course! at first i tried to cut new screw grips into it..but eventualy (partialy out of utter frustration because i had broken one of my screwdrivers on it) I jsut cut the bugger off. With lots of sparks.



And so you can see the dark spots from where the sparks burned the exterior..Not like I really care about it since i'm going to build new packaging for this thing.



Here goes the front, carefully being lifted with the magical evportator being revieled to the world (well untill I bury it in a liquid resevoir anyways).



And the back comes off just as easily w/o screws! it's like magic.




Here it is..fully exposed from the top and the side..as you can see it's starting to get dark and the pics where getting poor, I start using the actual light/flash tihngy on my camera hence forth... next step? strip some styrophome, remove the front fan(that's meant to blow cold air) and unscrew the evaportator so that i can bend some piping and be able to build a resevoir around it!!! YAH!




So the end of the first part of the project comes, the system is full stripped all the electrical connections touching the evaporator are gone (there was one lol). As well as the electrical being moved a little, the front fan is striped...aww ain't it purty? ;-)

SO that's it for this part of the post, enjoy!!! and as always I wants teh comments if uz haves them!

THat thing is huge almost looks like if you put a chair on the back of it you got your self your own mini scooter lol

Can't wait to see what you do with this...I have one of these lying around somewhere.

Mod on

So are you going to chill a resi of water to circulate or what is the plan?I have two evap-condenc-compressor setups waiting for my hands to create...Jo

yes i am going to build a resi around the evap unit and force the water to flow through iut before it gets to the outlet. Still not sure what the computer under it will actualy be but that'll all fall into place eventualy ;-). Got a bit sick today sadly :-( so might take longer then i expected especialy considering the store near me doesn't sell 5/8" OD coper piping *scratches head* it's so wierd.

Nice ...
It's good to see more people going the chilling route.

Are you planning on evacuating the system and rerunning the refrigerant lines,or will you be able to get the whole evaperator into a resevoir/cooler.
It looks like the existing captube and suction lines might get in the way.

yah i noticed that too, which is why I was looking for the sheet copper, I'm going to literaly construct a resevoir around the evap. That's why I was looking for Sheet metal.

I'm probably going to either braze the sheet metal onto the pipes or use something wierd like rubber cement or something where the pipes get in the way. Then jsut insulate the entire box heh. Any ideas/advice?

I don't know enough about this (yet0 to evacuate the gas and rerun the pipes... mainly cvause i don't even know howto braze everything ;-) that'll be the next project, this is sort of a 'lets get into phasse change slowly' project.

If you need any help in this area, then RBIEZE is definately the person to talk to. He is a master in the field

Geez,thanks snowman reading that makes me feel pretty cool .

But honestly I have so much more to learn yet,and soo much to do.
I still have to convert much of my book knowledge into practical hands on Know how.

But I'm driven to learn ,and I hope one day to earn that title.


Edit///
Aselus can you post a clearer shot from the side of the evaperator showing the compressor,suction line and captube ?

Your lucky if you have never worked with r-22 that you have two people on this site who are welling to help you. I have already started on the road to getting my masters in HVAC and RBIEZE i would hope would help to. If you need help or are confused just send me a PM. Alright hope everything works out greatly.

And another thought would be if you are going for subzero temps you are going to wanna undercharge the sys. the higher the psi the high the temps are on the coil. In hvac we have to keep the temps above freezing becuase if they drop below the coil will become a huge block of ice. that may help.

here are the pics ya asked for :-) now that they've been aproved ;-).

I don't get what you mean... I've gone bellow freezing with even a simple TEC system before...what's wrong with getting bellow freezing with the EVAP..i've already taken it past freezing on test runs. Not to mention there's plenty of epople that run theirs to well into the negatives

Damn,I think your going to have a hard time on this one .
The suction line is so close to the compressor that even if you manage to build a resevoir around the evaperator you wont be able to insulate it much near the compressor,which of course gets pretty hot.

It is possible to bend the tubes by hand,but you'll need to go bit by bit really slowwww.
if you want to try ,heres how you do it.
just remember,working with refrigerant is dangerous.

Wear safety glasses,a long sleeve shirt and gloves.
no one is responsible for your safety but you...Youve been warned!

usually people just use a pop cooler for a resevoir on systems like this.
so you'll only need a couple inches between the compressor and resevoir.

first SLIGHTLY bend the suction tube along the top ,away from the compressor and then the bottom towards the evaperator.
Dont try to bend it all in one spot ,or all at once.
Instead spread the bend along the leangth of the tube thats accessable.
Repeat gradually bending it till you get the minimum clearance you need.
for the cap tube just cut the zip ties and unroll what you need.

I cant stress enough how important it is to go slowww.
cause if you push it too far in one spot the tubing will crimp, or worse rupture spraying liquid refrigerant and oil over you and anything nearby.
If you do release the refrigerant indoors leave the area immediately.
while conventional refrigerants like R22,R12,R134a arent toxic they do displace oxygen and you can suffocate if you breath in too much.
Also NEVER EVER expose refrigerant to an open flame.
Toxic byproducts will be created such as Phosgene gas among other things, which can easily kill you.

hmm I was reading those too, by my measurements though there's a good 4cm in between the compressors little fluffy thing (that makes it not pop when the electrics hit it i'm guessing..but it's sticky and i'd rather not take it off) and the evaporator unit.

I think this is far more then enough space if i build my own resevoir out of copper and then just line it with insulation, and it wont get in the way of the radiator.

I was going to use plumbers epoxy to adjoin the copper to the two tubes (suction and i don't know what the other one is called) and then line the outside of the box with the same sort of insulation material that they well for the piping (i forgot what it's actualy called.

As for the actual outlet for the chilled liquid Iw as curious if there was any point to actualy using copper piping for it in stead of going strait to tygon.

If any of this seems unrealistic correct me so I don't bury myself hehehe ;-) thanks.

i am sorry i may be thinking of more a long the line of whole house HVAC but i know if you are running air push by a fan the coil will ice if it isn't charged right. becuase it has to be above freezing on the coil.

jsut got tipped off and recomended to build the resevoir out of plastic in stead of copper..didn't even think about that one heh.

fhsfiremanco1 - which coil are you talking about? *scratches head*

inside coil or your epv.c. coil the one that pushes cold air into the room.

heres a link to some pics of custom systems.
Unfortunately its in french,but of course pictures are universal.
