I was at a site where the sight glass was yellow, the system kept on pumping down every few days and i also found the suction flare nut on the TEXV had a leak.
I fixed the leak, changed driers and evacuated and all is good.
My question is how can moisture get into a system via a low side flare nut without the system runnning into a vacuum? The system in running on 134a and is a coldroom, the LP switch does cut out above 0psig.
Can the refrigerant drag in moisture (venturie effect)???
