Exergy analysis of Einstein's refrigeration cycle capable of using low qualified heat source.

Author(s) : WANG R. J., LIU D. P.

Summary

The Einstein cycle is a kind of single-pressure absorption refrigerator, without any moving components, driven by a low grade heat source. The original cycle is improved in this paper, a rectifier added in the cooling water system of the condenser/absorber, and two solution heat exchangers configured respectively before the generator and the evaporator to modify the thermal performance of the system. The paper describes exergy analysis models for all thermal parts of the improved cycle on the basis of the exergy analysis method. Energy-saving places and correlative improvements are presented to minimize the exergy losses and optimize the whole refrigeration cycle. In addition, the generator and the condenser are the main components where exergy losses exist.
