Performance analysis of turbine exhaust condensing heat recovery by absorption heat pump

Analyses the variable condition performance of heating system applying heat pump to recover the turbine exhaust condensing heat, proposes an optimizational design method and verifies its accuracy with test. The performance analysis result shows that the increase of circulating water outlet temperature is more conducive to improve the performance of heat pump. By simulation analysis with optimization method, finds out that thermal efficiency of the system is increased by 23.7%, and exergy efficiency of heating system is also increased from 46.8% to 62.0% compared with traditional heating condition. The test result and the analysis result of model are consistent, with the error less than 5%. It shows that the optimization analysis method has high accuracy, which can be used as the design principle for new projects.
