ok on the week end i finally got to make my first water chiller.
here are the parts below
first i pump R22 in for a while, turned off and turned on the chiller and let the Freon stabilise, it went high-220PSI and LOW 25PSI
it started to frost yayaayay
for the evaporator i used 20' of 1/4 OD copper tube and 5' of 0.026 captubing

Ok and this is what it finally looks like (below)
So far I only ran for about 20mins and it went from 17dec down to -1 deg in about 20mins.

how much did you spend to get that -1c?
or -1f ?
at the moment my personal computer is fauly, i just bough a new mother board and graphics card, cause of a leak before.
but the new motherboard doest like my SATA hardrives and i cant even install windows, so i cant tune this baby, most probly wont have a computer for about 5 weeks
i have left the chiller running this morning while im at work to see how cold she gets, cant wait.
over the next few weeks i think i might have to dig out my 130w tec and use that to fine tune the system untill i get my pc back in action.

all up cost me $260
but i have enoght pipe, captude left to make 3 more systems, with other compressors that i have.
-1 C this is only after 20mins
when i get home from work it would have been running for about
9 hours,
it is only a baby compressor, uses 110w.

Kayl where you got all this gear?
your local kirby refrigeration shop,
heres a link for all the aussies out there
http://www.kirbyjn.com.au/contacts/
click on where you are and they give you their address and phone number to call and speak to them, they even do online
they sell everything you need except refrigerant, they said that they can only sell if you have an account and a license
PHASE CHANGE ITCH, or should i say little voices in my head telling me all these ideas of what i could do to improve the system.
i just hope when i get home today that the chillier hasnt overheated and blown up.
the reason your temps are high it it took 20 min to get to -1C is because your cap tube is to resctive i would know since on my 1st chiller i used that sized cap tube it would hit -14C in 5hoursso i switched to 5ft of .036 and now ii would hit almost -50C in 20min or less

.031 cap tube is best for chillers.
opps thats what i mentOriginally posted by Gary Lloyd

when i got home it was -12 deg, but i had a very large ice bloke as well, gonna need some more anti freeze.

cause i have no computer to play on i have also started my brew,
for when i get thirsty on the computer
finally i decied to take my motherboard in today, they game me a new one, they didnt even check it, didnt even have to sign nothing. turns out the SATA part of the mother board was faulty kept crashing.
so im all back together now and ready to chill.
below is a picture of the esky all frozen over

ok i replaced the small fridge compressor for a 1\3 HP airconditioner compressor and i shortened the 0.026 captubing down to 4 foot, so once i have cheaked for leaks etc ill post temp's
is 220psi ok for high side pressure? 25psi ok for low side?
what is a good starting point to tune my system
Pressures depend upon temperatures. Normal low side pressure depends on what your coolant temp is, so we need to know both. Normal high side pressure depends on what your room air temp is, so we need to know both.
the other day i pressured tested the system but i have found a leak in my new system where the high side goes from copper pipe to the steal condenser that you find on the back of you every day life fridge, what type of brazing rod do i need to use, rods just don’t want to take and beads off?

very impressed that its your first waterchiller and its doing so fine, i cant wait to start building one, how much did that cost ya?
the cost is a little hard to work out and cause its in australian dollors wont mean much to most, most will infact think that is cost lots.
i had to start from scratch, get all the tools i need. $260
all the building materials i used just for this chillier didnt cost much at all $50 ($1 US=$.6 AUS)
when you get the copper its like a 15m roll (i only used 6 metres)
and i have enough cap tubing left for another system
i got the compressor for free,

ok on the week end i made two fittings to try and put some r290 into the system, i didnt have much luch though this one the thread didnt quite match, so it leaked.
the second try i decieded to modify a propane torch piece, that one fitted but it also was leaking a little.
this is me charging outside.
man this stuff is really could definetly need those glove.
when it was leaking i had drops of r290 falling to the ground it was cool. i managed to fill it a little, but i ran out of propane
i went to the camping store yesterday after work and picked up a 2kg bottle of R290, only cost $7 to fill too, this is going to fill a heap of systems. i got a camping gas oven hose chopped the end off and shoved a shraeder valve into it and put a couple of hose clamps on it.
pulled a vacuum and tried to fill it.
this time it worked like a dream no leaks. the only proble is that when i turn the compressor on it shakes then switches off, i wait for the relay to reset then try again, it does the same thing?

ok i have redone my system using my new condensor that i made and charged with R290. i managed to get to -22 deg in 1.5 hours, but i let a bit too much gas out trying to get the low side pressure under 50 psi, and now high side is only at 100 PSI
but i found out that i had burnt oil so i need to change the oil, for this type of compressor do i just drill a hole in the top of the compressor and drain the oil out?
