Dynamic simulation of a central chilling system of a large office building.

Author(s) : WANG S., WANG J., BURNETT J.

Summary

Dynamic simulation of a seawater-cooled chilling system is performed by using the dynamic models of centrifugal chillers, heat exchangers, seawater and chilled water networks, cooling coil, actuator, sensor, variable-speed pump and Direct Digital Control controller of Building Energy Management System. The on-line control strategies for the central chilling system are tested and evaluated by using them to control the living chilling system under different Air Handling Units dynamic loads in four seasons. The paper presents the models developed to simulate the dynamic system, the on-line control strategies developed for the chilling system and the evaluation of the strategies by system dynamic simulation.
