【摘要】 基于校园建筑实验楼不同朝向负荷需求差异,文中提出5种供能方案.利用TRNSYS软件建立了相应的供能系统模型并进行了为期1年的仿真模拟,根据模拟结果对比分析了各系统所需钻孔数及运行性能.研究结果表明:在5种供能方案中,整体式供能系统所需钻孔数约是分区式供能系统的1.57倍,同时整体式供能系统年末土壤温度与年初土壤温度温差为0.36℃,而在分区式供能系统中该温差为0.15℃～0.28℃.除此之外,分区式供能系统机组耗能更小,系统能效比也更高.其中,分区供能式太阳能辅助地源热泵系统的系统性能最优.更多还原

【Abstract】 Based on the differences of load requirements of different orientations of campus building experiment buildings, 5 energy supply schemes were proposed.TRNSYS software was used to establish the corresponding energy supply system model and the simulation was carried out for one year.According to the simulation results, the number of boreholes and operation performance of each system were analyzed.The results show that, among the 5 energy supply schemes, the number of boreholes required by the integral energy supply system is about 1.57 times that of the zonal energy supply system, and the temperature difference between the soil temperature at the end of the year and the soil temperature at the beginning of the year of the integral energy supply system is 0.36℃,while in the zonal energy supply system, the temperature difference is 0.15℃～0.28℃.In addition, the zonal power supply system has the lowest energy consumption and higher energy efficiency ratio.Among them, the system performance of the zonal solar-powered auxiliary ground source heat pump system is the best.更多还原
