| Abstract | with a concern of the waste of vast geothermal water during the operation of flash geothermal power plant in Fengshun and the residents' need of refrigeration, taking the advantage of two-stage LiBr-H2O absorption refrigeration system(TSARS) in the utilization of low grade heat, this paper proposed an integrated system which synthesize a TSARS to the original flash power generation cycle, improving the utilization efficiency of the geothermal water. First, with the field research made to establish the exergoeconomic model, analysis of this geothermal water integrated system was addressed. Then, Compared the ways of the geothermal water entering the TSARS, it is 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. |
