摘　　要：为避免地源热泵及其耦合系统运行存在冷热量不匹配,无法达到最佳节能效果的问题,本文通过结合实际项目,对办公建筑的夏季冷负荷和冬季热负荷需求进行模拟,分析地源热泵耦合不同冷热源系统的运行工况,建立多目标理论优化运行模型。研究结果表明,方案一中地源热泵耦合制冷机组为最优运行方案,系统综合能效比为4.15,系统效率优于其余方案,且运行能耗最低为103.8万kWh。本论文研究结果可对北京区域的地源热泵系统应用形式提供参考,有利于地源热泵及耦合系统在华北地区的推广和应用。To avoid the problem of unparallel cold and heat during the operation of ground source heat pump and its coupled system,which results in failure to achieve optimal energy-saving condition,this paper simulated the summer cooling load and winter heating load requirements of office buildings,analyzed the operational conditions of ground source heat pump coupled with different hot and cold source systems,and established a multi-objective optimization model based on theory based on actual projects.The research results showed that the optimal operating scheme was to couple the ground source heat pump with a refrigeration unit,which had a system comprehensive energy efficiency ratio of 4.15.This option has the highest system efficiency and the lowest operating energy consumption of 1.038 million kWh.The research results of this paper can provide reference for the application of ground source heat pump systems in Beijing,and promote the adoption and application of ground source heat pump and coupled systems in North China.
