摘　　要：针对双碳目标下未来供暖系统低碳化转型趋势,设计了一套耦合太阳能聚光光伏光热技术、生物质锅炉和地源热泵的低碳供热系统。使用TRNSYS软件搭建供热系统模型,以天津市某宿舍为研究对象,按照天津市典型年气象参数,采用NSGA-II算法对系统配置与运行参数进行多目标优化。结果表明:在蓄热水箱容积为9.9 m~3,地埋管孔数为8,蓄热水箱出口水直接供热温度为44.1℃,仅靠生物质锅炉补热的蓄热水箱出口水温为15.3℃条件下系统运行效果最优;优化后供热系统的聚光光伏光热系统太阳能转化总效率基本在70%以上,结合地埋管可实现对太阳能的高效转化和有效消纳;热泵系统性能系数高,可有效利用低温热源进一步实现高效供热。In view of the low-carbon transformation trend of the future heating system under the"carbon peaking and carbon neutrality"target,a low carbon heating system coupled with solar concentrating photovoltaic photothermal,biomass boiler and ground source heat pump was designed.The heating system model was constructed using TRNSYS software,and a dormitory in Tianjin was used as the research object.The NSGA-II algorithm was used to optimize the system configuration and operation parameters according to the typical annual meteorological parameters in Tianjin with multiple objectives.Results show that the system operates optimally under the conditions that the volume of heat storage tank is 9.9 m~3,the number of buried tube holes is 8,the direct heating temperature of water outlet from heat storage tank is 44.1℃,and the water temperature of water outlet from heat storage tank which only relies on biomass boiler for heat supplement is 15.3℃.The efficiency of the concentrated photovoltaic/thermal subsystem of the optimized heating system is basically above 70%.In combination with the buried tube,the efficient conversion and effective consumption of solar energy can be realized.The heat pump subsystem has a high coefficient of performance(COP)value and effectively uses the low temperature heat source to achieve efficient heating.
