Carbon emission reduction baseline study and case analysis during operation phase of large-scale ground-source heat pump systems
摘要：
通过大规模地源热泵技术利用浅层地热能对城市建筑群进行集中供冷供暖是一种高效的供能方法,具有良好的节能减碳潜力。目前关于小型地源热泵系统的碳排放及减碳能力有部分理论计算及数据调研,但缺乏以实际工程项目运行数据为基础的大规模地源热泵系统碳减排及其基准线情景分析研究。以安徽淮北市一个运行9年的大规模地源热泵系统为案例,通过运行数据分析及数值模拟方法,研究了项目基准线情景的适用性及碳减排量,并讨论了电力碳排放因子与土壤取放热平衡对项目碳减排量的影响。
Abstract：
The use of shallow geothermal energy to centrally cool and heat urban buildings through large-scale ground-source heat pump technology is an efficient energy supply method with good energy saving and carbon reduction potential. There are currently some theoretical calculations and data surveys on the carbon emissions and carbon reduction potential of small-scale ground-source heat pump systems. However, there is a lack of research on carbon emission reduction and baseline scenario analysis of large-scale ground-source heat pump systems based on actual engineering project operational data. Using the example of a large-scale ground-source heat pump system in Huaibei, Anhui Province, which has been in operation for 9 years, the applicability of the project baseline scenario and the carbon emission reduction are investigated through operational data analysis and numerical simulation methods. The influence of the electricity carbon emission factor and the soil heat balance on the carbon emission reduction of the project is discussed.
