A chiller model is developed to simulate the operational performance of centrifugal chillers based on the performance data from site measurement. The model is developed on the basis of basic mechanistic principles of chillers to ensure the reliability and accuracy of the model in a wide working range using the parameters identified using limited performance data. A pre-processor identifies the parameters of chillers using chiller performance data to ensure convenience of application. This paper presents the model, the strategy for model parameter identification, and the applications and validation of the model on an existing multiple chilling system in a building and on a chiller using manufacturer's catalogue data.
