Description

In this paper, a mechanistic model of a centrifugal chiller operated with variable-speed capacity control is presented. The model is useful for predicting the power requirement, the cooling capacity, and the conditions at which compressor surge develops. Results of the model are compared with measurements of power consumption and compressor speed taken at the central utility plant at the Dallas/Fort Worth airport. The model is used to investigate the performance characteristics of the D/FW chiller.
