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 DDC controller ofBEMS. 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 AHU dynamic loads in four seasons. This 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.
