This study reports on the actual energy and economic performances of a water source heat pump recently installed and operated at a Glasgow Subway station in the UK using subsurface water ingress to provide heating and domestic hot water. This follows from a previous publication that detailed the empirical measurements and design of a heating system designed on the basis of a 15-month monitoring period of the water flow and temperature. The perennial water flow at a relatively high temperature enabled the system to operate more efficiently than a typical heat pump system with boreholes or trenches. The performance of the water source heat pump has been monitored for a 4-month period, and the coefficient of performance as well as the energy saving is reported in the present study. The findings of this study not only indicate the energy, carbon dioxide and financial benefits of the heating system, but also highlight key issues during the operation in such a demanding underground environment. Further renewable heat potentials for the rest of the subway network and opportunities to commercialise the excess heat energy output are explored.

英国格拉斯哥浅层地热系统的热能：性能评估设计

这项研究报告了最近在英国格拉斯哥地铁站安装并运行的水源热泵的实际能源和经济性能，该热泵使用地下水入口来提供暖气和生活热水。这是从先前的出版物中得出的，该出版物详细介绍了基于15个月的水流量和温度监测期而设计的加热系统的经验测量和设计。相对较高温度的常年水流使该系统比具有钻孔或沟槽的典型热泵系统更有效地运行。水源热泵的性能已经监测了4个月，本研究报告了性能系数以及节能效果。这项研究的发现不仅表明了能量，二氧化碳和加热系统的财务效益，但同时也突出了在如此苛刻的地下环境中运行过程中的关键问题。进一步探索了地铁网络其余部分的可再生热潜力，以及将多余的热能输出商业化的机会。
