Thats about right. I dont care about your computer racing, though its nice it has a purpose and i hope my systems do what is expected. i race freezers, and this guys usin a broken stop watch. I dont mind competition, but itd be nice to see how much further i have to go, acuratly.Quote:

It will be changed soon enough as I am sure you want to know what my block looks like.
And cmon the "my dad could beat up your dad " comment was pretty funny.
captaincascade,
you need to go to XTW today with your Cascade rig. We need to try this Athlon 64 on it again.
OPP
Captain, you're just having more fun than the law allows, aren't you? :D
I have family in your area (Lawson Refrigeration in Irvine). I'm tempted to run out there and join in the fun... LOL
"Sits in the dark watching & learning. he has found a home":devil:
Captain, I also doubt FUGGER's temp measurements, but based on the numbers he is able to come close if his evap is really good, and hist load in the 80-140W range.
-107C evap temp would mean at least -112C SST, especially at these low temps. At -112C, our low side pressure is about 0.18 bara (~5.5 inch Hg). With an SC12 running at 60Hz, this is a suction pressure which is possible. It can be compared with a prommie running at -52C. Hard, but not impossible.
Still, to maintain this, he would need to condense at about -40C, thus with his high stage maintaining at least -45C at load. Now, this is hard for an SC12.
Thus, IMHO it is possible (read: not impossible), though I expect real evap temperature to be around -95C .. -100C.
cmon FUGGER, give us some more details about the thing. High stage evaporating temp, pressures, etc.
One more question: how do you do the low stage refrigerant expansion?
-97 is the absolute coldest ive seen with a 2 stage r-95 system. That was on a revco i rebuilt, and that was on the thermocouple that leads to the inlet to the 2nd stage evap directly sodered to pipe. -93, -94 is the coldest ive ever seen box temp. calculations and disney charactors aside, i do realize im arguing a dead point. i don't like to consider myself god, more like one of his children just like you. only difference is i was sent here to die for your sins. A great pestalence will soon be upon you. Repent!
join me in my not understanding why people would not believe i know what im talking about.
I really work at radio shack, live in my moms basement, and collect baseball cards.
yes gary i am having to much fun. lol
cmon you know its pretty funny guys.:-)
No doubt about that.Quote:

Still, -100C *is* possible with R508b in our systems, so fugger might indeed run this low.
To put it differently: have you ever seen a commercial single-stage reciprocal compressor R404a system running below -45C? Many here do it.
[/QUOTE]
CC, I was told I am not running straight 508B in second stage.
No problem for my 15+ hours of benching this weekend. Both compressors run cool and the whole suction side was very cool (iced at one point till we adjusted the PEV)
From my limited experiance I can comprehend that using a cap tube on a cascade will not produce the capacity needed just the insane temp range to fire up (been there, done that)
I dont want to give too many specs out because if I am wrong you guys will run me into the ground and I do not need an extra orafice expansion at this time. Reggie (HVAC engineer) will be online soon and be able to answer questions and correct my mistakes.
Dabit, high side R507B not in vacuum, no bubbles in sight glass. Low side PEV on the Evap head feeding a custom made distributor inside the evap head. Center pressure point retention mech for NO board warpage. four corners are not used. (gotta love a big C clamp)
You seen the base of my block in my avatar.
how can you see if there is bubbles in the sight glass? isn't it frozen?
are you useing a sporlan zz txv?
oh, and hey op, how far does my temp warm up on a load like -78c max? somethin like that. i had to rev it down so he could overclock the amd64. i was just bypassin a bit from high to low like a capacity control.
its not possible with those compressors, can you give me that?
It is possible to break away ice layer from the sight glass on first stage at any time. The second stage is under insulation and can be pulled back to expose. Do you need pictures.
I am a newb to know how far these compressors will go, but I do know they are operating very nicely.
picture a wave of electicity..... up and down ....up and down....
just a wavey line ok
now what the run cap does is creates another wave that doesnt go down and up as much and kinda keeps it uh .... not so wavey
it just kinda sorta uh,,, makes it more dc than ac i wanna say kinda...... less amps to make the waves,,, get it?
hey you removed your "how does a run cap question"?
I offered for you to come look at it early, could have saved some bandwidth and aggravatoin if you took me up on my offer. I even offered you $100 towards gas /shrug
oh well, lets see what yours can do. Eric wants to drive and Im cool with that.
we're doin what now?
did you understand the run cap?
Hey Guys, this is becoming sorta like, well, a food fight....Fugger, I'd like to come look at it for free! I could use a road trip! :D
yeah i know, im done makin an as outa myself. i just let my humor get carried away sometimes.Quote:

Not a problem, comes natural to some people. JK!
Just think, I would have bought you a prime rib dinner.
My cap question was lost when I was editing my post, not sure what happened. just noticed was gone.
Run cap drops the LRA, the compressor will function more efficiantly.
Don't forget, you still owe me that prime rib dinner. mmmmmm :D

I know your MO. ;) So I assume there is a lot of PM'n going on here, that the rest of us in the public bandwidth are not aware of.... but just for some insight in regard to the run cap scenario (only because I have been doing som reading)...
In a DC circuit, the capacitor acts like a storage device, in which an applied voltage can be stored for discharge upon the reverse of the polarity of the circuit. You see, in a DC circuit, no current can pass through a capacitor.
In an A/C current (application) however, the capacitor acts as a resistor (would act in a DC current). The start winding in an A/C current motor is of a lesser resistance conductor (thinner wire) than that of the run winding. The start winding cannot tolerate full voltage (current) during the continuous operation of the motor (other wise it would burn out. The capacitor acts as a "resistor" in order to reduce the "current" through the start winding, and allow it to produce an electromagnetic effect during the continuous operation of the motor, in order to increase motor efficiency (increase torque). There are certain other notes regarding the effect of the capacitor in the A/C circuit to explain, but I won't take up bandwidth (because if I were going to explain it... it would take a lot!!!! ... of bandwidth :p: )
I am sure that DaBit :p: can elaborate on the discoveries of Mr. Faraday, in regard to the application of capacitors and their inherant characteristics in A/C and D/C circuits (which are very dissimilar, and interesting nonetheless). :)
