Need help :cool:,
Does anybody know maximum discharge pressure ZB76 scroll compressor?
Is it possible if dirty oil happened can reduce discharge pressure?
Thanks

Maximum pressure is noted on compressor nameplate.
Still, compressor operating pressure could be relatively low but discharge superheat high.
Therefore, it is important to keep suction superheat low enough and, in that way, discharge superheat low.
Important is, that discharge gases are below 120°C.
