This paper introduces the integrated Small-Scale Plant-Based Air Filtration (SPAF) system, a novel integration of air filtration and urban agriculture, specifically designed for edge computing free cooling in urban environments. The SPAF's modular design enables extensive customization to meet various air quality requirements and agricultural needs. Through evaluation across different scenarios, the system has proven its effectiveness in particulate matter reduction, with a single unit showcasing substantial initial filtration efficiency, and even greater performance when multiple units are utilised in series. Beyond its air filtration capabilities, the SPAF system also contributes to urban agriculture, expanding planting areas and supporting the growth of local produce, thereby aligning with global sustainability objectives. Despite its promising applications, challenges such as the variability in filtration performance across different plant species, external climates, and the inability to ensure complete particulate matter removal, underscore the need for further research and potential integration with other purification technologies.

通过集成的小型植物过滤系统促进边缘计算环境中的城市农业和空气质量

本文介绍了集成的小型植物空气过滤（SPAF）系统，这是空气过滤和城市农业的新型集成，专为城市环境中的边缘计算自然冷却而设计。SPAF 的模块化设计可进行广泛的定制，以满足各种空气质量要求和农业需求。通过不同场景的评估，该系统已证明其在减少颗粒物方面的有效性，单个单元显示出可观的初始过滤效率，当多个单元串联使用时，性能甚至更高。除了空气过滤功能外，SPAF 系统还有助于城市农业、扩大种植面积并支持当地农产品的生长，从而与全球可持续发展目标保持一致。尽管其应用前景广阔，但不同植物种类的过滤性能差异、外部气候以及无法确保完全去除颗粒物等挑战，凸显了进一步研究以及与其他净化技术潜在整合的必要性。
