Abstract
In order to reduce the energy consumption of the air conditioning water system,the energy-saving control strategy of the air conditioning water system in a metro station in Guangzhou is studied.Using the sample data provided by the equipment manufacturer for parameter fitting,a more accurate equipment model is established,and Trnsys is used to build the basic model of the air conditioning water system of the subway station.For the phenomenon of'large flow rate,small temperature difference',a fixed temperature difference control strategy is proposed to reduce the energy consumption of the water system.The results show that compared with the fixed flow rate water system,the energy-saving rate of the water system with the fixed temperature difference control strategy can reach 25.86%.In the whole cooling season,compared with the conventional 7℃water supply temperature constant temperature difference control strategy,the air conditioning water system with variable chilled water supply temperature constant temperature difference control strategy saves about 3.40%.关键词
