摘　　要：针对夏热冬冷地区某高校宿舍用能特征,基于太阳能的两种利用方式分别设计了太阳能光热供能系统和太阳能光电供能系统。利用TRNSYS仿真软件模拟两种供能系统的运行特性,对比了两种系统的组件性能、经济性及减排量。结果表明:除假期时间外,太阳能集热单元的集热效率保持在40%左右,年太阳能保证率可达58%;并网光伏发电单元全年发电量为311 394 kW·h,发电量自用率达到70.5%。太阳能光电供能系统的年能耗费用较光热供能系统节省11万元,费用年值减少4.9万元,年碳排放量降低166 t。对光伏安装面积进行优化后可知,光伏安装面积每增加52 m^(2),光伏供能系统费用年值减少2111元。研究结果可为高校宿舍建筑选择适宜的太阳能利用形式提供参考和依据。According to the energy characteristics of a college dormitory in a hot summer and cold winter area,based on two ways of solar energy utilization,the solar thermal energy supply system and solar photovoltaic energy supply system are designed respectively.TRNSYS simulation software is utilized to simulate the operating characteristics of the two energy supply systems,and the component performance,economy and emission reduction of the two systems are compared.The results show that:except the holiday time,the solar energy supply system heat collection efficiency is maintained at about 40%,the annual solar guarantee rate can reach 58%;the annual generating capacity of grid-connected photovoltaic power generation system is 311 394 kW·h,with the self-utilization rate of generating capacity reaching 70.5%.The annual energy consumption cost of the solar photovoltaic energy supply system is 110 000 yuan less than that of the solar thermal energy supply system,the annual cost is reduced by 49 000 yuan,and the annual carbon emission is reduced by 166 t.According to the optimization analysis of photovoltaic installation area,the annual cost of photovoltaic energy supply system will decrease by 2111 yuan when the photovoltaic installation area increases by 52 m~2.The research results will provide reference and basis for choosing the appropriate form of solar energy utilization in university dormitory buildings.
