Got my phase change rig redone, need some help with charge
Ok, here's the deal. I can only measure high side and low side pressure/Saturated temperature and temp 4" from compressor inlet. My temp probe cant measure the compressor outlet cos I think its over 50ÂșC which is the limit for my probe (-40ÂșC to 50ÂșC).
I know that the air dT across the condensor is around 4ÂșC and room temp is in the region of 18ÂșC. I know Gary, you will be wanting the whole list but I dont have it right now. So think you can help?
Here is what i have so far:
R290
SST = -45ÂșC (4"Hg)
SCT = 26ÂșC (127psi)
Suction Line temp near compressor inlet = -27ÂșC
CPU temp 1ÂșC (this is take from socket diode, not the diode in the cpu die)
Processor running conditions = 1.95v @ 2740Mhz equates to:
142Watts and 88% 126Watts from http://www.benchtest.com/calc.html
Think you can help me get things cooler?
one more thing, I have 25mm thick armaflex hose insulation on the suction line, plenty insulation me thinks
