yay phase change is on the way.

sounds pretty kooshy, those gov contracts give em plenty to spread around :D we make some stuff for u guys... F-15, 767, 737, CH-47... mostly oil coolers

i'm a mechanical engineer... i just graduated last spring.
my capstone was to design a solar powered refrigeration and airconditioning unit so i have alittle experience. most of the info comes ...



Where did you go to school? I'm working on my BSME at Baylor right now. :D

r404 is a blend of r134a, HFC-143A, HFC-125... for the record

straight r134a does not look as promising... at least not at those pressures...

i may be wrong, but i'm pretty sure R134a is typically used at much lower pressures.
the saturation temperature (aka the temperature that it becomes a vapor... aka boiling) at 174psi is about 47*C. at say 27psi, it has a saturation teof 0*C

yes, r134a would boil at much lower pressure than r404a. therefore keeping danger :)p) down at production. :)

Thats not the only reason that low pressures are preffered. you also have to consider if the system were to get a leak. you would rather atmospheric air be drawn in rather than a HFC compound be blown out of the system. either way your system is no good, but in the latter case, you dont have chemicals in your breathing air!


btw, i went to ohio northern university. its a small private school. where is baylor?
 
ok first run,, im just in bios. at 1.65v i can hit 3.4ghz. Will try and go higher later today, wont post when i try 3.6 which is my goal. Will up the voltage more.. hmmmm wonder if i dont have it set right.. running at 3.4ghz@1.65,,, bios says the chip is at 65*F.... i figure it would still be below freezing
 
i actually switched back to the mobo in this signature.. everywher eon the net i am seeing says that the voltage on the cpu can go up to 1.8.... mine only goes to 1.55.... hope a bios upgrade fixes it
 
figured out how to crank the voltage up more.

yayyyyyyy fx 60 running@3.6ghz@ -7*C

well it posted,, havnt installed an os yet
 
one thing though cwiz... the tube that goes from the unit to the cpu is in a sleeve... it has wire wrapped around inside it.. Is that to prevent kinking or is a wire that heats up to prevent condensation?

The bios says it is still at subzero.. yet the block is super hot. And the condenser is still at Negative 47C
