Commercial absorption chiller models for evaluation of control strategies.

Author(s) : KOEPPEL E. A., KLEIN S. A., MITCHELL J. W.

Summary

A steady-state computer simulation of a direct-fired, double-effect water-lithium bromide absorption chiller in the parallel-flow configuration was developed from first principles. Unknown model parameters such as heat-transfer coefficients were determined by matching the model's calculated state points and COP against nominal full-load operating data and COPs obtained from a manufacturer's catalog. The model compares favorably with the manufacturer's performance ratings for varying water circuit (chilled and cooling) temperatures at full-load conditions and for chiller part-load performance.
