Abstract

Air movement dries surfaces by increasing evaporation and convection, which may prevent mould growth. Cladosporium sp. is used as the test organism (dominant fungi in the envelope of rural houses in hot summer and warm winter areas), and the effect of fans on inhibiting mould growth on building materials is investigated. Surface mould growth on materials was simulated and compared after rain leakage and surface condensation, and spore germination was studied in high humidity, with or without airflow. The results are as follows: (1) Airflow has an evident inhibitory effect on mould growth on wet building materials. This observation was linked to the availability of moisture content in the building materials. (2) Airflow can slow the appearance of visual mould on the material surface. Mould did not appear on the gypsum surface due to the airflow, and mould growth on a wood surface was delayed for about two days. (3) Periodically, spore eluates were examined by electron microscopy to determine the stage of spore germination, and it was found that airflow delayed mould spore germination for about 2–3 days.

气流对建筑表面霉菌的抑制作用和机制研究

空气流动可通过增加蒸发和对流使表面干燥，从而防止霉菌生长。以 Cladosporium sp.（夏热冬暖地区农村房屋围护结构中的主要真菌）为试验生物，研究了风扇对抑制建筑材料上霉菌生长的影响。模拟并比较了漏雨和表面冷凝后材料表面霉菌的生长情况，并研究了高湿度、有无气流条件下孢子的萌发情况。结果如下(1) 气流对潮湿建筑材料上的霉菌生长有明显的抑制作用。这一观察结果与建筑材料的含水量有关。(2) 气流可减缓材料表面出现可视霉菌的速度。由于气流的作用，石膏表面没有出现霉菌，而木材表面的霉菌生长则推迟了约两天。(3) 定期用电子显微镜检查孢子洗脱液，以确定孢子的发芽阶段，结果发现气流可延迟霉菌孢子发芽约 2-3 天。

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.
