Reply To: Sub cooling


subcooling is a penalty in steam cycle efficiency and also increases the amount of oxygen that can be entrained in the condensate. It has one positive aspect in that it increases condensate pump NPSH, preventing cavitation in those pumps. Modern IR scanning detectors/ cameras can be configured to scan the ACC tube bundle to detect the degree of subcooling on each bundle, and perhaps this could be used to schedule fan speed to minimize subooling.
