摘　　要：采用TRNSYS软件搭建系统模型,以生命周期经济成本为目标函数,调用Hooke-Jeeves算法,在保证供暖季室内温度达到供暖要求的前提下,对蓄热水箱容积、太阳能集热器面积、生物质锅炉额定热功率、太阳能集热器倾角四个关键参数进行优化。结果表明,优化后联合系统的太阳能保证率为27.5%,水箱容积与太阳能集热器面积之比为101 L/m^(2),最佳集热器倾角为φ+18°(φ为当地纬度),生物质锅炉的额定热功率为建筑在供暖季的瞬时最大热负荷的1.27倍,优化后的系统生命周期经济成本降低了17.8%。生物质锅炉额定热功率、太阳能集热器面积、蓄热水箱容积、太阳能集热器倾角对系统生命周期经济成本的影响依次降低。研究结果可为联合系统的设计应用提供参考。TRNSYS software is used to build a system model, with the system life cycle economic cost as the objective function, and the Hooke-Jeeves algorithm is called to ensure that the indoor temperature reaches heating during the heating season. Under the premise of requirements, the four key parameters of hot water storage tank volume, solar collector area, biomass boiler rated thermal power, and solar collector inclination angle are optimized. The results show that the solar energy guarantee rate of the optimized combined system is 27.5%, the ratio of the water tank volume to the solar collector area is 101 L/m^(2), best collector inclination angle is φ+18°(φ is the local latitude), the biomass The rated thermal power of the boiler is 1.27 times the instantaneous maximum thermal load of the building during the heating period, and the economic cost of the optimized system life cycle is reduced by 17.8%. The influence of the rated heating power of the biomass boiler, the area of the solar collector, the volume of the hot water storage tank, and the inclination of the solar collector on the economic cost of the life cycle of the system is successively reduced. The research results can provide reference for the design and application of the combined system.
