A novel integration of chemisorption refrigeration cycle and a scroll expander was investigated for the cogeneration of … of 490 W. The valuable experience and the inspiration on system optimization has been reaped and discussed through this …

Exergy or the available energy is based on the second law of thermodynamics and goes back to Maxwell and Gibbs. It is … the exergy content and not the energy content, that truly represents the potential of the substance to cause change …. Exergy is the only rational basis for evaluating the system performance. The aim of this project is to study in detail the …

heat pipe/ejector refrigeration cycle is discussed, in this paper. The needed driving capillary forces are firmly … established. The basic characteristics of the system, such as entrainment ratio, coefficient of performance, exergy efficiency and … about 0.30 at Te=10°C, Tc=30°C and Tg=100°C. Also, the second law efficiency of the heat pipe/ejector refrigeration cycle …
