Abstract
An algorithm calculates, in real time, the overall heat transfer coefficient for an air-cooled chiller system and compares this value to a reference value corresponding to a new machine operating with a clean condenser. Based on this comparison, an indication is displayed to inform a user of the degree of degradation in condenser performance.
