This paper examines through a thermodynamic analysis the feasibility of using waste heat from marine Diesel engines to drive a vapor compression refrigeration system. Several working fluids including propane, butane, isobutane and propylene are considered. Results showed that isobutane and Butane yield the highest performance, whereas propane and propylene yield negligible improvement compared to R134a for operating conditions considered.

This paper deals with a thermodynamic analysis of a vapor compression refrigeration system with the new refrigerant R125/R600a blends, parameters and factors affecting the performance are investigated, and also a comparison with that of R22 is presented. Encouraging results are obtained, at a certain concentration of R125 in mixtures, the R125/R600a refrigerant blends perform better than R22 but with loss of volumetric cooling capacity in air conditioning applications. Which may provide useful information for alternative refrigerants.

In this paper, comparative thermodynamic analysis of system-1 (multiple evaporators and compressors with individual expansion valves) and system-2 (multiple evaporators and compressors with multiple expansion valves) has been presented which is based on energy and exergy principles. The comparison of systems-1 and -2 using ecofriendly R410A, R290, R1234YF, R502, R404A, R152A and R134A refrigerants was done in terms of COP (energetic efficiency), exergetic efficiency and system defect. Numerical model has been developed for systems-1 and -2 for finding out irreversibility and it was observed that system-2 is better system in comparison with system-1 for selected refrigerants. It was also found that R152a shows better performances than other considered refrigerants for both systems.
