Abstract

Abstract:

Solar collectors are frequently challenged by their inherent intermittency and seasonality. However, phase-change materials (PCMs) are considered a highly promising energy carrier due to their excellent thermal storage density and constant phase-change characteristics, providing a new research direction for enhancing collector stability. This paper presents the energy and exergy analysis methods for integrating phase change thermal storage technology with solar collectors and derives performance evaluation and economic analysis indicators for integrated collectors. It also summarizes that the packaging methods for PCMs in integrated collectors primarily include geometric and integral packaging, and different types of collectors use different packaging methods. Second, the paper discusses the impact of integrating PCMs on the performance and economic benefits of flat plate collectors, vacuum tube collectors, and photovoltaic/thermal collectors. It summarizes the primary technologies for optimizing the performance of integrated collectors, including increasing the heat transfer area by adding fins, enhancing the thermal conductivity of PCMs, and improving the heat transfer efficiency using micro-heat pipe technology. Finally, the impact of integrated PCMs on the comprehensive performance and economic feasibility of solar collectors was summarized. The optimization and research direction of integrated collectors were prospected to enhance their practical applicability and contribute to the efficient use of renewable energy.

Key words: solar collector, phase change heat storage, collector efficiency, enhancing heat transfer
