Second law analysis of multi-stage lithium bromide/water absorption heat transformers.

Author(s) : LEE S. F., SHERIF S. A.

Summary

Thermodynamic second law analysis in conjunction with first law analysis gives a premium to the consideration of the quality of energy over the quantity involved in a thermal system and can lead the way to improve the system's performance. Performance comparisons of single-, double-, and triple-stage absorption heat transformers (AHT) using a lithium bromide/water solution as the working fluid were conducted and analyzed. Simulation of these systems was employed to evaluate the first law performances, while the thermal properties, entropy, and exergy of the working fluids were also calculated to analyze the second law efficiencies under different operating conditions.
