Field measurements can be made to determine the heat transfer coefficient of operating chiller condensers. The heat transfer coefficient can be used to identify condenser fouling, a major cause of increased energy usage in chiller systems. Case studies are used to show how heat transfer coefficients can be used to detect fouling of condensers and the economic impact of condenser fouling on chiller operation.
