Research progress on the coupled application of radiation cooling materials and phase change materials in building envelopes

随着全球气温上升和能源消耗增加,建筑节能技术的重要性日益凸显。辐射制冷材料(RCM)和相变材料(PCM)在建筑围护结构中的应用,为降低建筑能耗提供了有效途径。介绍了RCM与PCM的基本原理、分类及其在建筑围护结构中的耦合应用研究。研究表明,RCM与PCM耦合技术能够有效提升建筑物的隔热和储热性能,在夏季降温与冬季保温方面均优于单一材料的使用效果。然而,RCM与PCM的耦合技术在实际应用中仍面临气候适应性、居住舒适度、力学性能影响以及材料耐久性等挑战。未来的研究应综合考虑这些因素,以进一步优化该技术的实际应用潜力。

As global temperatures rise and energy consumption increases,the importance of energy-saving technologies in buildings is becoming increasingly important.The application of radiative cooling materials(RCM)and phase change materials(PCM)in building envelopes provides an effective way to reduce building energy consumption.This paper introduced the basic principles and classification of RCM and PCM and their coupled application studies in building envelopes.The study showed that the coupling technology of RCM and PCM could effectively improve the thermal insulation and heat storage performance of buildings,and was better than the use of a single material in both summer cooling and winter heat preservation.However,the coupling of RCM and PCM still faced challenges in practical application,such as climate adaptation,occupant comfort,impact of mechanical properties and material durability.Future research should take these factors into account to further optimize the potential of this technology for practical application.
