针对我国丰顺地热电站大量地热尾水直接排弃的问题和当地居民对制冷负荷的需求，基于双级溴化锂吸收式制冷循环（ TSARS）在低品位热能利用方面的优势，提出将双级溴化锂吸收式制冷循环应用于地热电站尾水余热的回收，形成地热梯级综合利用系统，以进一步提高地热水的利用率。采用火用经济学分析方法，通过对电站的实地调研，建立地热水TSARS火用经济模型，进而对地热水级联到TSARS的两种可能模式（串联和并联）进行对比分析。结果发现地热水以并联方式供入TSARS具有较好的火用经济性能，同时对设计工况下的地热水并联TSARS的各设备进行了火用经济分析评价，为后期实际工程做参考。

With a concern of the vast geothermal waste water during the operation of flash geothermal power plant in Fengshun and the residents′need for cooling load, this paper proposes an integrated sys-tem which synthesizes a TSARS to the original flash power generation cycle, improving the utilization effi-ciency of the geothermal water by taking the advantage of two-stage LiBr-H2 O absorption refrigeration sys-tem( TSARS) in the utilization of low grade heat.First, with the field research made to establish the ex-ergoeconomic model, analysis of this geothermal water integrated system was addressed.Then, Compa-ring the ways of the geothermal water entering the TSARS, it was found that the parallel way is better than the cascade on the exergoeconomic performance.In addition, exergoeconomic analysis of each equipment of the paralleled TSARS was made.All above provide a certain reference to the further actual engineering application.
