Experimental and Mathematical Analysis of the Performance of a Small Scale Absorption Cycle (NH 3-H 2 O and LiBr-H 2 O)

Air conditioning plays a vital role in modern life, but its high energy consumption, particularly in vapor compression cycles, is a major concern. This study explores absorption cycles as an alternative, where the compressor is replaced with components powered by heat instead of electricity, potentially leading to reduce energy consuming. The study has three main approaches: theoretical analysis, experimental and validation. The theoretical analysis uses Engineering Equation Solver (EES) to model the system's performance, focusing on Coefficient of Performance (COP) and cooling capacity, for two working pairs NH 3 -H 2 O and LiBr-H 2 O. The experimental setup was designed to validate the theoretical model. The results from the theoretical analysis show good agreement with a maximum deviation of around 0.6%. Furthermore, the analysis indicates that the LiBrH 2 O pair has better COP and cooling capacity than NH 3 -H 2 O by approximately 33%. This suggests that LiBr-H 2 O absorption cycles have the potential to be a more efficient and sustainable alternative for air conditioning systems.
