Towards the enhancement of the applications of solar powered absorption chiller systems for Residential/ commercial Applications: Opportunities and Challenges, A review

The market demand for sustainable cooling solutions keeps increasing with the businesses need for efficient systems that lower greenhouse gas emissions. Solar-powered absorption chiller systems present an advanced solution to vapor compression cycles because they generate cooling through absorption processes that produce minimal environmental impact. These systems utilize solar thermal energy to power absorption cooling processes. The transition of solar absorption chiller technologies from scientific research to large-scale applications remains limited with the fact that conventional cooling methods control more than 97% of the global market. This review paper connects academic research to industrial adoption through an analysis of solar-powered chiller system developments and identification of major obstacles to their industrial deployment. This paper starts by presenting an overview of absorption chiller technology history and its current state. The review investigates multiple solar-powered absorption chiller types through an evaluation of recent advancements in solar collectors and auxiliary heating elements and thermal storage solutions. This paper evaluates simulation and optimization modeling progress because these tools help develop better system designs which enhance performance alongside cost-effectiveness and reliability. The review divides experimental studies into two categories which include parametric testing for optimal operating condition identification and long-term performance evaluations for industrial-scale project practicality and durability assessment. The experimental results demonstrate essential performance metrics including coefficient of performance (COP) and solar fraction which determine the feasibility of solar-powered absorption chillers. The review concludes by discussing the necessary policy frameworks and standards and certification processes which will drive solar-powered absorption chillers from research prototypes to commercial products. The proposed recommendations aim to connect research findings with industrial deployment by focusing on affordable dependable and expandable system designs. The paper combines current developments with strategies to address existing obstacles to establish future directions for solar powered absorption chiller systems which will help researchers and industry stakeholders achieve wider adoption and sustainable cooling solutions.
