摘要
本文基于武汉市39个地源热泵示范项目的能效测评,总结分析了地源热泵技术在武汉市的应用效果。结果显示地源热泵技术在武汉地区应用良好,系统与机组能效系数较高,各类地源热泵系统与常规空调系统相比节能明显,取得了较好的经济和社会效益,同时也发现各类地源系统普遍存在水系统输送能效比偏高等问题。测评结果可为后续项目的推广应用提供参考,同时也可为处于类似气候分区和地质条件的地区提供一定参考。
This study analyzes and summarizes application effect of ground source heat pump （GSHP） technology based on energy efficiency assessment of 39 GSHP demonstration projects in Wuhan.The results shows that the application of GSHP technology in Wuhan area is running well,the units and systems have higher energy efficiency and the energy saving of all kind of GSHP systems is obvious compared with conventional air conditioning systems.These demonstration projects have achieved great economic and social benefits.However,it also shows a problem that there is higher transportation energy efficiency ratio of water system in all kinds of GHSP systems.The result can provide reference for application of subsequent projects.It can also provide certain reference in a similar climate subarea and geological conditions.
