Abstract (EN): This study focuses on the theoretical performance of a single-stage absorption heat transformer (SSAHT) using the working pair H2O/LiBr for low-temperature waste heat recovery. A thermodynamic model was implemented in Engineering Equation Software (EES) considering a waste heat temperature of 60 degrees C in a small-scale SSAHT. A sensitivity analysis was performed where important system parameters were varied, including the inlet temperatures, mass flow rates, and solution heat exchanger effectiveness. Their impact on different AHT performance parameters (COP, ECOP, GTL, and FR) was evaluated, and these results provided practical guidelines that were utilized to optimize the SSAHT operating conditions.
