ASSESSMENT OF THE STATE OF THE ART AND PERFORMANCE OF HYBRID WATER–AIR SOLAR COLLECTORS

Abstract

This study is devoted to the assessment of the state-of-the-art development and performance characteristics of hybrid water–air solar collectors, analyzing their structural configurations, heat transfer mechanisms, and operational efficiency aspects. Recent studies indicate that the implementation of dual-flow channels and optimized absorber designs significantly enhances thermal efficiency and temperature stability compared to conventional single-medium collectors. The analysis considers key performance indicators such as thermal efficiency, heat gain, and system adaptability under varying climatic conditions. Despite technological advancements, further optimization of absorber materials, flow configurations, and thermal storage integration remains necessary. The results confirm that hybrid water–air solar collectors provide effective solar energy utilization in residential and small-scale applications and play an important role in the development of sustainable and energy-efficient thermal systems.

Keywords
