Abstract

Taking an existing public building as an example, the mathematical model of each equipment module of the chilled station and the TRNSYS custom module are established on the basis of the measured data. The mathematical model of "chilled station cooling capacity-equipment power" is proposed and established. The full-frequency control strategy based on device contribution rate is proposed. The TRNSYS simulation platform is used to simulate a public building chilled station in the cooling season. The result shows that the seasonal energy efficiency rate of the public building air-conditioning system is 2.15 times as high as the original after applying the new control strategy.
