论文摘要
作为国际教育研究研究的一部分，提出了新型UVC领导的空气清洗器的概念设计。主要组件是尘埃滤清器组件，一个UVC室和风扇。尘埃滤清器旨在抑制灰尘积累，从而阻碍UVC腔室操作。该创新是在UVC室内的，其中包括一种新型的湍流生成网格，可增强腔室中的空气混合和新颖的LED布局，以实现具有合理功耗的SARS-COV-2病毒和TB细菌气溶胶的足够杀死。两种疾病都遭受了低至中收入的国家的影响，这项研究是提供非药物解决方案来减轻此类疾病的空气传输的一部分。使用计算流体动力学和UVC射线方法的低到高保真度用于表明该设计可以为Covid和TB提供97％以上的杀伤力，而流感-A的杀伤力则高于92％。这是100 l/s的流速，功耗小于300W，设备尺寸既便携，也可能适合通风管。讨论了研究和教育方法，以及对廉价的尘埃过滤器性能以及辐射和流场的分析。
A conceptual design of a novel UVC-LED air-cleaner is presented as part of an international educational-research study. The main components are a dust-filter assembly, a UVC chamber and a fan. The dust-filter aims to suppress dust accumulation that will hamper the UVC chamber operation. The innovation is in the UVC chamber that includes a novel turbulence-generating grid to enhance air mixing in the chamber and a novel LEDs layout to achieve sufficient kill of the SARS-CoV-2 virus and TB bacterium aerosols with a reasonable power consumption. Both diseases have hit hard low to medium income countries and this study is part of an effort to offer non-pharmaceutical solutions to mitigate the air-transmission of such diseases. Low to high fidelity methods of computational fluid dynamics and UVC ray method are used to show that the design can provide a kill above 97% for Covid and TB, and above 92% for influenza-A. This is at a flow rate of 100 l/s, power consumption of less than 300W and a device size that is both portable and may also fit into ventilation ducts. Research and educational methodologies are discussed, along with analysis of the inexpensive dust-filter performance and the irradiation and flow fields.
