本文报告了对复合材料（环氧树脂/石蜡球）和石蜡填充（环氧树脂/金属管）热物理性能的实验研究结果，这些复合材料的开发旨在改善 PCM 的不同性能，并为潜热存储系统开辟广泛的应用领域。本研究的目的是使用 PCM 复合材料作为被动式太阳能墙的集成组件。所提出的复合 TROMBE 墙允许每天将太阳能存储在建筑围护结构中，并在晚上恢复原状，并可能控制通风空气层中的空气通量。建立了一个实验装置来确定这些复合材料对热诱导的热响应。结果表明，这些复合材料在固态和液态下最重要的热性能，如“表观”导热率、储热能力和熔化潜热。对石蜡填充复合材料（环氧树脂/金属管）热物理性能的实验研究表明，这些材料同时具有高储热能力和增强的传热能力。
This paper reports the results of an experimental investigation on the thermophysical properties of composites materials (Epoxy resin/paraffin spheres) and (Epoxy resin/metal tubes) filled with paraffin developed to improve different properties of PCM and open a wide field of applications to latent heat storage systems. The objective of this research is to use PCM composite as integrated components in a passive solar wall. The proposed composite TROMBE wall allows daily storage of the solar energy in a building envelope and restitution in the evening, with a possible control of the air flux in a ventilated air layer. An experimental set-up was built to determine the thermal response of these composites to thermal solicitations. The results have shown that most important thermal properties of these composites at the solid and liquid states, like the “apparent” thermal conductivity, the heat storage capacity and the latent heat of fusion. Experimental investigations of the thermophysical properties of composites materials (Epoxy resin/metal tubes) filled with paraffin have shown that these materials combines a high heat storage capability and an enhanced heat transfer at the same time.
