摘　　要：以复合式地源热泵系统地下环路系统投资最小为优化目标,基于能量平衡基础建立优化目标函数,对复合式地源热泵系统的地下环路系统进行优化分析;在平衡全年地层冷热负荷的基础上,分析冷却塔等辅助源运行控制策略的优缺点以及控制特点和适用的场合。研究结果表明:冷却水流量、热泵机组进水温度和地温初始条件对地下水流量和系统初投资有显著影响。For the aim of the least investment of the underground loop system, hybrid ground source heat pump systems were analyzed and optimized on the basis of the optimization aim equation under the energy balance. The advantage and disadvantage, control character and suited occasion of the operating control strategy of the assisted heat source were analyzed based on the balance of annual cooling or heating load for the ground layer. The analy- sis results show that cooling water flow, inlet/outlet water temperature of heat pump unit and initial condition of ground temperature affect underground water flow and initial cost of hybrid ground source heat pump systems obviously.
