本文基于上海某办公楼一次泵变流量系统的研究数据,利用系统仿真软件TRNSYS进行系统部件的建模和系统平台的搭建,提出优化运行策略。在基于建立好的仿真平台,提出了提高冷冻水供水温度的系统运行策略,模拟分析不同供水温度时系统能耗对比,相比传统的7℃出水温度,9℃的出水温度对室内空气品质影响较小,并且系统能耗大约降低17.6%。同时,利用仿真平台从系统角度对变风量系统和定风量系统进行了能耗模拟,结果表明,变风量系统相对定风量系统节能14.3%。
Based on the research data of primary pump variable flow system in an office building in Shanghai, this paper uses the system simulation software TRNSYS to build the system components and set up the system platform, and puts forward the optimization strategy. Based on the established simulation platform, a system operation strategy for raising the temperature of the chilled water supply was put forward. Compared with the energy consumption of the system at different water supply temperatures, compared with the traditional outlet temperature of 7 ℃, the effect of the outlet temperature of 9 ℃ on the indoor air quality Smaller, and the system energy consumption decreased by about 17.6%. At the same time, the simulating platform is used to simulate the energy consumption of the variable air volume system and the fixed air volume system. The results show that the relative variable air volume system saves 14.3% energy compared to the fixed air volume system.
