Abstract

Widespread utilization of geothermal energy as a clean energy source can reduce the use of fossil fuels and thereby protect the environment. Previous combined heat and power (CHP) systems using low-temperature geothermal heat as a heat source have limited utilization of geothermal heat. In this study, a cogeneration system based on organic Rankine cycle (ORC) and absorption heat exchanger (AHE) is designed. We analyzed the thermal efficiency, exergy efficiency, and economics of the proposed system utilizing 85 °C low-temperature geothermal heat, and the optimal operating fluid for this system is discussed. The results show that the optimal working fluid for the proposed system is R245fa. Using R245fa as the working fluid, the proposed system can achieve an exergy efficiency of 61.39%, when the heat source outlet temperature can be as low as 23 °C, while the proposed system can achieve the lowest LCOE of 0.082 ($/kW ·h) when using R22 as the working fluid.

摘要

将地热能作为清洁能源广泛利用可以减少化石燃料的使用，从而保护环境。以前使用低温地热能作为热源的热电联产（CHP）系统对地热的利用有限。在本研究中，设计了一种基于有机朗肯循环（ORC）和吸收式换热器（AHE）的热电联产系统。我们分析了利用85°C低温地热能的该系统的热效率、火用效率和经济性，并讨论了该系统的最佳运行工质。结果表明，该系统的最佳工作流体是R245fa。使用R245fa作为工作流体，当热源出口温度低至23°C时，该系统的火用效率可达61.39%，而使用R22作为工作流体时，该系统可实现最低的度电成本0.082（美元/kW·h）。
