矿井水源热泵系统的经济学分析
Exergy economics analysis of mine water source heat pump systems
摘要：
以单位冷、热成本及单位冷、热量成本为指标，分别建立了矿井水源热泵系统与制冷机组+锅炉房系统的热力学模型，进行了热经济学分析。结合工程实例，计算比较了两种系统的热力学成本。结果显示，从热经济学角度来讲，矿井水源热泵系统明显优于制冷机组+锅炉房系统，尤其体现在冬季工况。

Abstract：
Taking the costs of unit cooling or heating exergy and unit cooling or heating quantity as evaluation index, sets up the thermodynamic models of mine water source heat pump system and refrigeration unit plus boiler room system separately, and analyses the thermal efficiency of the two systems. With a project, calculates and compares thermodynamic costs of the two systems. The results show that from the viewpoint of thermal economics, the mine water source heat pump system is obviously better than refrigeration unit plus boiler room system, particularly in winter condition.
