Leak isolation logic for closed-volume system

摘要

A method for isolating a leak in a closed-volume liquid system (10) comprises circulating a fluid through a plurality of isolatable zones (Z1) and a non-isolatable zone (Z2, Z3) in a closed-volume liquid system (10), detecting a leak in the closed-volume liquid system, isolating all of the isolatable zones (Z2, Z3) from the non-isolatable zone (Z1), sequentially detecting if the leak is present in the non-isolatable zone (Z1) and each of isolatable zones (Z2, Z3), and taking corrective action after the leak is detected.
