Abstract

This article presents a comprehensive analysis of the design, integration, and performance evaluation of a photovoltaic (PV) solar-driven aqua-ammonia diffusion absorption refrigeration (DAR) system. The present approach emphasizes a thorough indoor experimental phase to inform the design process and selection of the PV solar system for integration with the DAR unit. The experiments cover various start-up conditions, thermal power inputs to the generator, and evaporator loads, with temperatures measured at key points of the DAR unit. Steady-state results across a wide range of operating conditions are used to create performance maps and identify dynamic characteristics, crucial for estimating generator power for specific cooling loads. Outdoor experiments are conducted to evaluate the performance of the PV-driven DAR unit under typical hot climate conditions. The operation time of the DAR unit reaches 94 h and maintains an evaporator temperature between −9.5 °C and 3.5 °C. PV cells achieved an average daily efficiency of 12–13 %, with an overall system COP of approximately 0.055. These results demonstrate the system's capability to maintain effective cooling under varying solar conditions, making it suitable for remote areas without conventional electricity.

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
