摘　　要：研究了太阳能与生物质锅炉联合供暖系统在我国北方农村的应用,目前太阳能和生物质能为中国北方地区农村采暖较佳用能。以辽宁锦州某单体式建筑采暖系统为研究案例,利用DeST软件搭建北方农村单体式建筑模型,以动态负荷为基础搭建太阳能与生物质锅炉联合供暖系统的TRNSYS模型。通过改变太阳能集热器面积与蓄热水箱体积占比来确定参数值,结合费用年值法进行分析。结果表明,该研究案例下,在集热器面积为50 m2、蓄热水箱体积为2.1 m3时,所耗费用最低为4910元/a,太阳能保证率达到62%,此时系统的经济性最佳。This paper studies the application of solar energy and biomass boiler combined heating system in rural areas of northern China.At present,solar energy and biomass energy are the best energy for rural heating in northern China.The study took a single building heating system in Jinzhou,Liaoning as the case study.DeST was used to build a single building model in the northern rural areas.TRNSYS model for the solar energy and biomass boiler combined heating system was set up based on dynamic load.By changing the solar collector area and the storage tank volume ratio,paramaters’value was determined.Combined with the annual cost method,the optimization analysis was conducted.The result shows,for the case study,when the collector area is 50m2 and the corresponding storage tank volume is 2.1 m3,the minimum cost is 4910 yuan/year with a solar fraction of 62%,and the economy of the system is best at this point.
