Abstract

This paper presents the design of a unit-type solar self-insulating composite exterior wall panel, which integrates a solar collector panel, photovoltaic (PV) panel, and insulation board into a single unit module. The research explores the utilization of an optimized solar collector panel to provide hot air indoors and proposes methods of application on facades. Using Fluent for simulation, it was found that on a sunny winter day, the thermal performance of the optimized solar collector panel increased by 94.68% compared to its pre-optimized state. A three-day experiment showed a maximum average temperature rise of 41.23 °C at the air outlet, close to the simulation. Finally, the energy efficiency and economic benefits of the study were calculated, which showed an energy saving rate of 65.47% for the composite exterior wall panels. This research provides ideas for solving the winter heating problem in cold regions’ buildings and the design application of self-insulating composite exterior wall panels in prefabricated buildings.

太阳能加热复合外墙板优化设计及热性能研究

本文设计了一种单元式太阳能自保温复合外墙板，将太阳能集热板、光伏板和保温板集成为一个单元式组件。该研究探索了利用优化的太阳能集热器在室内提供热空气，并提出了在立面上应用的方法。利用Fluent进行仿真，发现在阳光充足的冬季，优化后的太阳能集热器的热性能比优化前提高了94.68%。为期三天的实验显示，出风口最高平均温升为41.23℃，与模拟结果接近。最后，对研究的能效和经济效益进行了计算，结果表明，复合外墙板的节能率为65.47%。本研究为解决寒冷地区建筑冬季供暖问题和自保温复合外墙板在装配式建筑中的设计应用提供了思路。

期刊介绍： Frontiers of Architectural Research is an international journal that publishes original research papers, review articles, and case studies to promote rapid communication and exchange among scholars, architects, and engineers. This journal introduces and reviews significant and pioneering achievements in the field of architecture research. Subject areas include the primary branches of architecture, such as architectural design and theory, architectural science and technology, urban planning, landscaping architecture, existing building renovation, and architectural heritage conservation. The journal encourages studies based on a rigorous scientific approach and state-of-the-art technology. All published papers reflect original research works and basic theories, models, computing, and design in architecture. High-quality papers addressing the social aspects of architecture are also welcome. This journal is strictly peer-reviewed and accepts only original manuscripts submitted in English.
