摘　　要：基于上海市不同运营年限地铁车站送回风温湿度、室外温度及送风量实测数据,对不同运营年限车站冷水机组节能潜力、地铁车站负荷与客流量、室外气温的关系进行分析。研究结果表明:运营初期的地铁车站平均负荷率偏低,可以通过卸载一台冷水机组来提高负荷率,冷水机组平均COP上升1.4,单个标准车站空调季冷水机组方面可节省约10444.6元;运营年限更久的地铁车站由于在较高水平负荷率下运行,卸载冷水机组后冷水机组平均COP下降0.3,造成能量损耗;运营年限的4年地铁车站负荷与室外气温的相关性不显著;工作日与非工作日车站实际冷负荷差距不大;早晚高峰时段的实际冷负荷会出现不同程度的上升。The measured data of return air temperature,humidity,outdoor temperature,and air supply volume at metro stations with different operation years in Shanghai are used as the basis for analyzing the energy-saving potential of chillers,the relationship between the load and passenger flow at metro stations,and outdoor temperature with different operation years.The results show that the average load rate of metro stations in the initial operation period is low,and the load rate can be increased by unloading one chiller,resulting in an average COP increase of 1.4 for chillers,and a cost saving of approximately 10444.6 yuan for a standard station during the cooling season.For metro stations with longer operation years,since they operate at a higher load rate,unloading a chiller results in an average COP decrease of 0.3,leading to energy loss.The actual cold load change curve of stations with longer operation years is more similar to the outdoor temperature change curve,and there is not a significant difference in the actual cold load between workdays and non-workdays.The actual cold load during peak hours in the morning and evening will increase to varying degrees.
