摘　　要：为提高VRV空调系统节能效果,提出了1种基于提前启停控制和室内温度设定的优化运行策略。以上海市某办公建筑为例,首先基于实际运行数据分析空调系统运行现状;其次基于EnergyPlus软件建立办公楼标准层建筑模型和VRV空调系统模型,分析空调最佳启停时间与室外温度的关系、空调设定温度与运行能耗的关系,并以此为基础提出优化运行策略;最后以夏季典型日为例模拟标准层VRV空调系统在优化运行策略控制下的运行情况,并与现行策略对比,分析空调系统在优化运行策略控制下的节能效果以及各房间室温的波动情况。In order to improve the energy⁃saving effect of the Variable Refrigerant Volume(VRV)air⁃conditioning system,this paper proposed an optimal operation strategy based on pre⁃start and pre⁃stop control and indoor temperature set⁃points.With the VRV air⁃conditioning system of an office building in Shanghai as an example,the operation status of the VRV system was analyzed according to the actual operation data.Then,the building model of the standard floor of the office building and the VRV system model were established by using EnergyPlus software.Based on the research of the relationship between the optimal pre⁃start and pre⁃stop time and the outdoor temperature and the relationship between indoor temperature set⁃points and the operating energy consumption of the VRV system,an optimized operation strategy was proposed.Furthermore,taking a typical summer day as an example to simulate the operation of the VRV system under the control of the optimized operation strategy and compare with the simulation results of the current strategy,the energy⁃saving effect of the VRV system and the fluctuation of room temperature under the control of the optimized operation strategy were analyzed.
