Scratch-built video chiller
Okay, I've got my 24' of .031" cap tube in, and right now, running a 10"Hg vaccum, R-409A, I have a minus 45F evaporator with a minus 12F return gas temperature.
I'm about 130F going in to my condenser
100F out.
Much like the R-404A Prommie retrofit, I don't seem to have much subcooling, of course my shop is 95F.
My discharge pressure is about 140psig, which puts the high side saturation at about my condenser outlet temperature. I've got 6' of the 24' cap tube wrapped around the suction.
