摘　　要：公共建筑空调系统能耗较高的原因之一是系统在实际运行中能效较低。基于具体案例系统仿真对空调系统优化控制策略进行研究。分别对机组序列优化控制、水泵变频优化以及机组出水温度优化进行研究,确定系统优化策略。借助TRNSYS模拟仿真软件,模拟仿真优化前后系统全年运行状态与能耗情况,验证优化策略节能效果。仿真结果表明,优化后系统全年能耗与优化前相比节能13.2%。One of the reasons for the high energy consumption of public building HVAC system is the low energy efficiency of the system in actual operation.In this paper,the optimal control strategy of the air conditioning system is studied based on system simulation of the practical case.Optimal control strategies have been confirmed after carrying on the studies about the optimization of the unit number control of heat pumps,variable frequency of water pumps,temperature set point of the supply water,respectively.Based on the TRNSYS simulation software,the system operation conditions and energy consumption have been simulated in order to verify the energy-saving effect of the optimization strategies.The results show that the system energy consumption has been reduced by 13.2%after adopting the optimization strategies.
