地源热泵技术及经济性分析

Technology and Economic Analysis of the Ground Source Heat Pump

地源热泵是指利用土壤或地下水的低温位热能和蓄热性能的一种热泵系统。作为一项新技术,在中国尚处在初步开发利用阶段。结合地源热泵工程技术方面的相关问题对其经济性进行分析,在系统的初投资和年运行费用两个方面与集中供热体系进行比较。

The ground-source heat pump is the heat pump system that uses the low level heat energy and regenerative properties of soil or groundwater.As a new technology,its development and utilization are still in the preliminary stage in China.Technical issues of ground source heat pump engineering related to the analysis of their economic benefit are expounded.The initial investment and annual running costs of the system are compared with the aspects of central heating system.
