摘　　要：合理利用太阳能、地热能等可再生资源是解决环境污染和减少碳排放的有效途径之一,满足当下高效利用可再生资源和能源利用多样化的需求。以安徽省合肥市三栋小型建筑为对象,在TRNSYS动态仿真软件内按照零能耗建筑设计标准确定三种建筑的围护结构及内热源参数,计算三种建筑的冷、热、电及生活热水的负荷,并以使用周期总费用LCC为目标函数,供冷/热、生活热水、零能耗建筑要求为约束条件,采用单目标Hooke-Jeeves算法对三种建筑的地埋管深度及太阳能集热器参数进行优化并得到最优解集。结果表明,相对于未优化前全寿命周期成本LCC分别减少了26.99%、25.41%、31.30%。优化后的参数可保证系统稳定运行且更具有经济、节能效益。Reasonable use of renewable resources such as solar energy and geothermal energy is one of the effective ways to solve environmental pollution and reduce carbon emissions,and meet the current demand for efficient use of renewable resources and diversified energy utilization.This paper takes three small buildings in Hefei City,Anhui Province as the object.In the TRNSYS dynamic simulation software,the envelope structure and internal heat source parameters of the three buildings are determined according to the zero-energy building design standards,and the cold,heat,electricity and heat sources of the three buildings are calculated.The load of domestic hot water,with the total life cycle cost LCC as the objective function,and the cooling/heating,domestic hot water,and zero-energy building requirements as constraints.The single-objective Hooke-Jeeves algorithm is used for the buried pipes of the three buildings.The depth and solar collector parameters are optimized and the optimal solution set is obtained.The results show that LCC has been reduced by 26.99%,25.41%,and 31.30% compared to the full life cycle cost before optimization.The optimized parameters can ensure the stable operation of the system and have more economic and energy-saving benefits.
