Structure optimization of radiant cooling panel: A literature review and assessment.

[Display omitted] • A review of the structural optimization of RCP (radiant cooling panel) was conducted. • Systematically analyzed the status of heat transfer performance parameters of RCP. • Comprehensive introduction and mechanism analysis of RCP structural optimization methods. • The adaptability and engineering prospects of the optimization methods were assessed and justified. Radiant cooling, as an energy-saving, thermal comfort-enhancing, and noise-free air conditioning technology, has garnered increasing attention in recent years. But the risk of condensation and the resulting issue of insufficient cooling capacity becomes prominent when applied in high-heat and humidity regions such as East Asia. Structure optimization of radiant cooling panels is a crucial approach to address these issues, and many scholars have conducted research on the past decade. However, it is rarely comprehensive reports on those optimization methods due to the independently researched and innovated by different paths. This paper provides a comprehensive review of various optimization methods for radiant cooling panels including enhanced heat transfer design, surface treatment, and material selection, and then analyzes the implementation mechanisms, as well as the advantages and disadvantages of its engineering applications. Finally, an analysis of the future development of radiant cooling panels was presented from a practical application perspective. It is intended to support the research on the optimization of radiant cooling panels and the increasing applications of radiant cooling systems worldwide. [ABSTRACT FROM AUTHOR]
