kayl how much time does ur chiller have to work to reach that temp? how much liquid do u have in the system?

i used 5 litres 50/50 anti freeze then topped it up with about 1-2 litres of straight antifreeze, it took about 3 hours to get to this temperature. i have just changed the cap tube from 4 foot of 0.026 cap tube, it use to take 1hr 22 mins to go from room to -30deg, but wouldnt get any colder even after an hour or so. so when im tunning i think i will be shortening that cap tube little by little.

my latest chillier

**kayl** · 05-23-2004, 05:08 AM

and this is the res
the first run i got -25 deg in 3mins
then i lengthened cap tube and i got to -35deg in 15m mins

and this is the front view

Awesome

Howed you make that res/HX whatever? Looks pretty cheap... Will it withstand methanol?

**kayl** · 05-23-2004, 05:33 AM

it's just 20' 1/4 OD copper pipe round around a map gas bottle then placed inside a plastic pipe with end caps.
i think i need to use 3/8" copper pipe for the refrigerant to evaporate properly as the 1/4" is too small. and i think that there might be a restriction in the capillary line. next time i think i will try 0.031" capillary line instead.

there are holes in the top of the res for the coolant mix to circulate through my water block, i just need to fix my water pump connection, at the moment the only way my pump can work is if its submerged cause one of the fittings broke off
when im finished the res can be sealed air tight,
i guess methanol water mix would be ok, just mix so that the end result of mix is just over the full capacity of the system to minimize the amount of flammable material used

Thought it was plastic... Da_bit did that and the plastic HX basicley got anniliated by the methanol...

Anyone try to chill water with ice from refrigerator for food?
I have no possibility to buy compressor (anyone have one that not neccessary?

) and only built watercooler for system (but for all components - CPU,VGA,MB,HDD,PSU) complete fanless.
And I want to build a waterchiller

And here is my latest:

And of course it is for sale.

gary, do u have pics of the inside of it? it looks pretty cool as usual

**Gary Lloyd** · 06-04-2004, 06:29 AM

The inside looks just like TECHChiller #2, except the new evap/res is half the size. With each chiller, I am downsizing the evap/res. The intent is to eventually find the optimum size evap/res, and then sell them to people who want to build their own chillers.

Actually, I designed an evap/res that is very small and would rival the plate heat exchanger in efficiency, but it is extremely complex and labor intensive, containing a mixture of both series and parallel circuits, which would make it very expensive. I'm currently working on a design that comes reasonably close, but holds the costs down.

Well time to jump into the fray.
Here is a unit I picked up today to play with.
It has hit -30.1 since I snapped the pic. About 25 min runtime.
Now I need a res.

Gary, Do you build your own reservoirs ? If so out of what ?
I like the all in one aproach and think I have enough room in the case if I build a res as opposed to a cooler. Any pointers would be appreciated. After I get that nailed down then I will tune the charge and see what it will do.

Thanks
Shawn

My evap/res assemblies are all brazed copper. Very strong and very efficient. I will soon be finished testing designs and will be offering them for sale.

i got the same AC

did u have a tough time getting some of the screws out. on mine i had to dremel the head of the screw clean off just to get the covers off

**sc00by71** · 06-15-2004, 06:44 PM

No I managed to get mine out ok. Having a good screwdriver helps (Snap-on) I wrench for a living so I am used to tight fasteners. I haven't had the time to complete my chiller yet. Too many irons in the fire.

Good luck with your project, hopefully I will have mine done soon.
