Effect of load-sharing operation strategy on the aggregate performance of existed multiple-chiller systems

The load sharing strategy is influenced by many parameters such as the condition of the chillers and compressors, the piping arrangement, and the heat loss from the chilled water piping where these parameters may overwhelm the individual chiller performance. Accordingly, the load-sharing operation strategy may vary from case to another and should be periodically examined to verify proper system operation, rectify the existing chiller performance and identify chiller faults. Therefore, the need for maintenance can be predicted and the standby chiller may be eliminated.
