greetings all I am currently working on a chiller system with hotgas unloading,,they took discharge gas from a port directly above DSV and piped it through a normally closed solenoid operated ,,non adjustable regulator and directly into
crank case of a copland semi hermetic compressor ,there is a pressure control controlling the solenoid,, it reads low side pressure .. the pressure control was replaced recently what I am asking is what should the pressure control cut in and cut out be set at ,,i was thinking 57 lbs cut in and 65 lbs cut out ,,(R-22)....system also has OPSS.. and freeze protection..
thanx Jim Kruse
