Building a dynamic simulation model of the centrifugal chiller in consideration of control processes is highly important for evaluating all-year performance of the chiller.A dynamic simulation model of the air-conditioning system utilizing PSF centrifugal chillers is built to simulate the dynamic operating parameter and performance in response to system control strategies.A simulation is conducted for a typical building in Guangzhou from May to October.Results show that the annual COP of the PSF centrifugal chiller reaches 7.33,and annual COP of the cooling station reaches 5.53.
