摘　　要：通过分析项目所在地能源状况,结合当地供暖需求和现状管网等实际情况,采用Trnsys软件对全年热负荷进行模拟计算,确定采用槽式聚光集热器配合相变蓄热设备,并以电锅炉作为辅助热源的太阳能供热系统。通过软件模拟太阳能供热系统,供暖期辅助热源电锅炉总补热量为总耗热量的8%左右,实际太阳能保证率可达92%左右,总体运行费用较低,证明该太阳能供热方案合理可行。By analyzing the energy situation of the project site, combined with the actual situation of local heating demand and current pipe network, Trnsys software is used to simulate and calculate the annual heat load, and the solar heating system using trough concentrating collector with phase change heat storage equipment and with electric boiler as the auxiliary heat source is determined. Through the software simulation of the solar heating system, the total heat supplement of the auxiliary heat source electric boiler during the heating period is about 8% of the total heat consumption, the actual solar fraction can reach about 92%,and the overall operation cost is low, which proves that the solar heating scheme is reasonable and feasible.
