Abstract

This study presents an in-depth experimental and numerical analysis of an innovative Composite Trombe Wall (CTW) system utilizing a natural zeolite-perlite composite plate as thermal mass, aimed at advancing sustainable building applications. This novel system uniquely combines the high specific heat capacity of natural zeolite with the low thermal conductivity of perlite, optimizing thermal storage and retention in passive solar energy applications. A comprehensive Computational Fluid Dynamics (CFD) model was developed to simulate natural convection and heat transfer dynamics, and validated against experimental data. Results indicate a maximum temperature differential of 11.5 °C between indoor and ambient conditions, demonstrating the CTW system's potential to enhance energy efficiency and indoor thermal comfort in nearly zero-energy buildings (nZEB). This research contributes a significant advancement by showcasing the practicality of sustainable, locally sourced materials in enhancing passive solar heating systems, thereby establishing a new benchmark in eco-friendly building technology.

采用天然沸石/珍珠岩复合板作为热质的 Trombe 墙模型的实验和数值分析，用于近零能耗建筑

本研究对利用天然沸石-珍珠岩复合板作为热质的创新复合材料墙（CTW）系统进行了深入的实验和数值分析，旨在推进可持续建筑应用。这种新型系统独特地结合了天然沸石的高比热容和珍珠岩的低导热性，优化了被动式太阳能应用中的热存储和热保持。我们开发了一个全面的计算流体动力学（CFD）模型来模拟自然对流和传热动力学，并根据实验数据进行了验证。结果表明，室内和环境条件之间的最大温差为 11.5 °C，证明了 CTW 系统在提高近零能耗建筑（nZEB）的能源效率和室内热舒适度方面的潜力。这项研究展示了可持续的本地材料在增强被动式太阳能供热系统方面的实用性，从而为生态友好型建筑技术树立了新的标杆，是一项重大进展。

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
