As a virgin user I am straight away asking the assistance of your wise and experianced minds.
I am currently working on an aged milk vatutilizing a kelvinator modrl 72 condensing unit,the problem is it not only runs a TX valve but also a hot gass bypass.
O.K. the hot gass bypass may be for downloading and anti-ice but it in turn is controlled by a pressure controll tapped off the TX pressure equaliser.
I have the system running reasonably well but am still experiancing some frost back to the compressor even though in am running a 8 k superheat.
Does any one have any good ideas on the reasioning for the extensive array of controls and any advice for the liquid return
