Comment on “Thermodynamic analysis of absorption refrigeration cycles using the second law of thermodynamics method” by S. Aphornratana and I. W. Eames [Int. J. Refrigeration 18 (4), 244–252, 1995]
Abstract A paper has been published in International Journal of Refrigeration, second law analysis of vapour absorption refrigeration (VAR) system using different mathematical expressions which obey thermodynamics principles. The present paper attempts to discuss and comment on the paper. Addition or subtraction of exergy of the heat flux (or exergy of heat transfer) in mathematical expression of internal irreversibility, are not meeting to direction principles of exergy flow. Therefore, internal irreversibility expressions must be corrected for future research based on second law in the field of VAR system.
