摘　　要：采用TRNSYS软件对某高校图书馆地源热泵与燃气锅炉耦合供暖系统进行了模拟研究,对比分析了不同热源所承担热负荷比例的变化对供暖系统经济性的影响。研究结果表明:当地源热泵机组和燃气锅炉分别承担40%和60%的建筑热负荷时,耦合供暖系统经济性最优。此时,单位供热量费用为0.16元/(kW·h),相较传统电加热供暖系统节约了62.6%的运行费用,全年减少二氧化碳排放2461 t,减少氮氧化物排放37 t。This article uses TRNSYS software to simulate the coupling heating system of a ground source heat pump and a gas boiler in a university library,and compares and analyzes the impact of changes in the proportion of heat load borne by different heat sources on the economy of the heating system.The research results indicate that when the local source heat pump unit and gas boiler respectively bear 40%and 60%of the building heat load,the coupled heating system has the best economic performance.At this time,the unit heating cost is 0.16 yuan/kWh,which saves 62.6%of operating costs compared to traditional electric heating systems.It reduces carbon dioxide emissions by 2461 tons and nitrogen oxide emissions by 37 tons throughout the year.
