Parametric study and thermal sensitivity analysis of a triple effect absorption refrigeration system

Year: 2025

Type: article

Abstract: Absorption refrigeration systems represent an efficient means of cooling utilizing waste heat, with triple-effect absorption refrigeration systems outperforming their double and single-effect counterparts in terms of efficiency. This study conducts energy and exergy analyses on a triple-effect absorption refrigeration system, focusing on internal heat balance and thermal sensitivity to maximize efficiency. The analysis pinpointed the most sensitive thermal sensitivity areas within the system, highlighting the high-pressure condenser (HPC) outlet and medium-pressure condenser (MPC) outlet as critical points. Notably, increasing the temperatures of HPC and MPC leads to enhanced COP and ECOP, with a mere 5 K rise in HPC exit temperature resulting in a remarkable 57 % boost in system performance. Similarly, elevating the MPC operating temperature by 5 K yields a significant 34 % improvement in COP value.
