Abstract

The Carnot analysis method was proposed for the simplification of the thermodynamic analysis of the absorption cycle

by the comparison of the absorption cycle and the compression cycle.The system with two evaporators and two absorbers that is suitable for the large temperature difference of chilling water was developed through the investigation of the energy conversion in the cycle.In addition

the Carnot model of the present system was established and its efficiency of the ideal cycle was obtained.Then the effects of the different heat resources and relevant parameters on the efficiency were evaluated and the efficiency difference between the present system and the simple cycle was compared.The present system with two evaporators and two absorbers may improve the efficiency of the absorption cycle.
