摘　　要：以整个系统的视角综合考虑多种优化措施对空调系统运行优化进行研究,对系统节能有重要意义。以武汉市某医院为研究对象,研究了其空调系统的夏季节能运行优化措施。基于TRNSYS仿真软件建立了该医院中央空调系统仿真模型,对系统运行参数进行优化,通过水泵变频运行、冷水机组与水泵启停策略优化及冷冻水温度动态调节实现系统节能运行。水泵变频调节后,空调系统比定频运行节能22.03%,优化机组和水泵启停策略可进一步节能5.29%,采取冷冻水温度动态调节措施,能耗可再降低5.45%,采用综合优化后的运行策略,系统制冷季能耗总体降低约30.18%。研究结果可为夏热冬冷地区医院中央空调系统运行提供参考。It is of great significance to study the operation optimization of air conditioning system from the perspective of the whole system by considering various optimization measures comprehensively.A hospital in Wuhan is researched to study the energy-saving operation optimization measures of its air conditioning system in summer.Based on TRNSYS simulation software,the simulation model of the central air-conditioning system of the hospital is established,and the operation parameters of the system are optimized.The energy-saving operation of the system is realized through the pump frequency conversion operation,the start-stop strategy optimization of the chiller and the pump,and the dynamic adjustment of the chilled water temperature.After the pump frequency conversion adjustment,the air conditioning system saves 22.03%energy compared with the fixed frequency operation,and further saves 5.29%energy by optimizing the start-stop strategy of the unit and the pump.By adopting the operation strategy after comprehensive optimization,the overall energy consumption of the system in the cooling season is reduced by about 30.18%.The research results can provide reference for the operation of central air-conditioning system in hospitals in hot summer and cold winter areas.
