Abstract

Abstract: A LiBr-H₂O absorption cascading conversion system driven by waste heat for power,cool and heat was investigated.By the system,a part of energy of waste heat was transformed into power and a part of remaining energy was transformed into cool and heat so as to realize energy cascading conversion,thus achieving a more rational use of waste heat.Through analyzing the theoretical knowledge and the results of the thermodynamic calculations about the system,effect of the generator pressure and temperature on energy transformation was gained.

Key words: LiBr-H₂O refrigeration system, thermodynamics analysis, performance of generator
