Re: Vaporize POE Oil?
The oil and refrigerant are designed to be miscible, so by deisgn it's difficult to get the refrigerant out of the oil by vacuum. Hence, the relaxed requirement once there's refrigerant in the oil.
My understanding is that POE likes water even better than it likes refrigerant, and that once it's there, a vacuum pump WILL NOT get it out.
I've been looking for some kind of a vapor pressure or evacuation chart that includes POE (or even mineral oil) in the mix, rather than just water in a jar, but so far, I've struck out.
It's an extension for a thread here:
