SARS-CoV-2, the virus that causes the disease Covid-19, is primarily transmitted through respiratory droplets which linger in enclosed spaces, often exacerbated by HVAC systems. Although research to improve HVAC handling of SARS-CoV-2 is progressing, currently installed HVAC systems cause problems because they recirculate air and also use ineffective virus filters. This project will develop a novel method of eliminating SARS-CoV-2 and future viruses in enclosed spaces using Photocatalytic Oxidation (PCO) technology, previously employed to remove organic contaminants and compounds from air streams using the irradiation of titanium dioxide (TiO2) surfaces with ultraviolet (UV) lights causing the disintegration of organic compounds by reactions with oxygen (O) and hydroxyl radicals (OH). The O and OH reactions can also destroy viruses.Using the established results from previous R&D, the project will develop a novel TiO2 coated copper fibre mop system, which will both act as a fan and provide the essential very large surface area for UV irradiation. Research will include optimizing UV frequencies, intensity, and improvement on photocatalytic oxidation by doping of TiO2 with metals, followed by in vitro studies investigating the effects on SARS-CoV-2, and other endemic coronaviruses. The rotating fibre fan, illuminated by a high intensity UV, allows viruses to be eliminated in an efficient, nearly silent system, adaptable for small or larger applications.Engineering will include optimization of two demonstrators: a low-profile wall unit and free- standing floor unit. These low cost, efficient systems will be demonstrated to industry to allow rapid adoption for buildings and public transport systems.

SARS-COV-2是导致疾病共同19的病毒，主要是通过呼吸液滴传播的，这些液滴在封闭空间中徘徊，通常会因HVAC系统而加剧。尽管改善SARS-COV-2的HVAC处理的研究正在进行中，但目前安装的HVAC系统会引起问题，因为它们会循环空气并使用无效的病毒过滤器。该项目将开发一种新的方法，可以使用光催化氧化（PCO）技术在封闭空间中消除SARS-COV-2和未来病毒，以前用来使用二氧化钛（Tio2）表面与紫外线（UV）光线（UV）散布（UV）的孤岛（UV）散布的钛表面去除空气流中的有机污染物和化合物，从而消除了有机污染物和化合物，从而消除了有机污染物（UV）。羟基自由基（OH）。 O和OH的反应也可以破坏病毒。使用先前的研发的既定结果，该项目将开发出一种新型的TiO2涂层铜纤维MOP系统，该系统将充当风扇，并为紫外线照射提供必不可少的非常大的表面积。研究将包括优化紫外线频率，强度以及通过用金属掺杂TiO2对光催化氧化的改善，然后在体外研究研究对SARS-COV-2和其他地方性冠状病毒的影响。由高强度紫外线照亮的旋转纤维风扇允许在有效的，几乎保持沉默的系统中消除病毒，适用于小型或大型申请。工程将包括优化两个示威者：低调的壁单元和自由站立的地板单元。这些低成本，高效的系统将被向行业展示，以允许对建筑物和公共交通系统的快速采用。
