安徽省某办公楼地源热泵系统检测及能效评估

Performance Detection and Energy Efficiency Evaluation of Ground-source Heat Pump on An Office Building in Anhui Province

以安徽合肥某办公楼的地源热泵系统为对象,对其能效评估的基本方法、研究内容及评估程序进行了详细介绍。对该系统冬季运行工况进行短期能效测试。在实测数据的基础上,计算了该项目的机组制热性能系数及热泵系统能效比,进而对系统进行综合能效评估,以具体数据的形式分析出该系统的节能效益、环境效益和经济效益。研究得出的结论表明:该建筑的地源热泵系统不仅能够有效节约能耗,由此带来的环境效益和经济效益也较为显著。

The basic methods,research contents and evaluation process to evaluate the energy efficiency were introduced in details,taking a ground-source heat pump system of an office building in Hefei as the object.The short-term efficiency test on the winter running performance of the system was established,and further the unit heating coefficient of performance and the system energy efficiency ratio were calculated on the basis of the measured data,and then the comprehensive evaluation of the system energy efficiency was obtained,so as to analyze the energy-saving benefit,environmental benefit and economic benefit of the system in the form of specific data.Research conclusion shows that the energy-saving benefit of the heat pump system is remarkable,at the same time,the environmental benefit and economic benefit are both considerable.
