摘　　要：以水蓄能地源热泵系统为研究对象，通过理论与实验相结合的手段，对该系统进行在线优化运行控制的理论分析与实验研究。研究结果表明：在线优化运行控制能有效提高系统的运行效率，相对于地源热泵独立直接供能系统，应用优化运行控制后，大区间变容量运行热泵的性能系数可从3．0最大增至约4．5，同时在峰谷电价的基础上可为用户节省大量运行费用，日运行费用的节省比例（节费率）约为21．8％，可为在线优化运行控制技术在工程应用中的推广提供数据支持。Taking the ground source heat pump system with water heat storage as research subject, the online optimal operation control of the system was carried out through the combination of theoretical analysis and experimental research means. The results showed that relative to the independent direct energy supply system of ground source heat pump, the online optimal operation control can improve the system coefficient of performance （COP） effectively; the COP of heat pump operation in large range of variable capacity can be increased from 3.0 to 4.5 at the most by the application of optimal operation control. Meanwhile, the operation cost can be saved based on the peak valley price. The daily operation cost saving ration is about 21.8%, which can provide data support for the promotion of online optimization operation control technology in engineering application.s data support for the popularization of online optimal operation control technology in engineering application.
