A study on feasibility of VOC sensor integration

Island Clean Air Inc (ICA)是一家总部位于温哥华的公司，设计，制造和销售广泛的 空气过滤器系列适用于不同行业，如汽车喷漆车间，印刷和图形等。这些 系统配有三级过滤器，能够去除颗粒物（PM）， 挥发性有机化合物（VOC）。它们是用户友好的，并在用户定义的气流操作 所涉及的唯一成本是运营（电能）和维护（更换过滤器）。根据 对于ICA技术团队，过滤器在低于平均水平运行时必须每6个月更换一次 在车间等条件下，或在空气污染严重的情况下，每2 - 3个月进行一次。这些系统使用 当大量的PM积聚在过滤器上时，集成的流量计可以检测到。在这一点上， 指示器点亮，其建议用户更换空气过滤器。然而，目前还没有传感器 在这些单位，提供有关空气质量的信息，在真实的时间为用户观察的效率， 过滤系统随着时间的推移提高空气质量。这样的特征还可以使用户关闭 当空气足够清洁时，过滤系统，以降低操作和维护成本，以及 提高过滤器的效率和寿命。 理想地，将VOC感测系统与过滤单元集成，以向环境提供即时反馈。 实时空气质量。使用两个这样的传感器，一个在过滤器的上游，一个在过滤器的下游， 允许测量过滤器是否被VOC饱和，这可能发生在 大量PM 将VOC传感器集成到ICA的空气过滤系统中将使该公司具有显著的竞争优势， 优势超过竞争对手。ICA将成为唯一一家能够提供实时评估的公司 空气清洁度以及过滤效率，以及降低系统以节省 能源

Island Clean Air Inc. (ICA) is a Vancouver-based company that designs, manufactures, and markets a wide range of air filtration units for different industries, such as automobile paint shop, print and graphics, etc. These systems are fitted with three stage filters that are capable of removing particulate matter (PM) as well as volatile organic compounds (VOCs) from the air. They are user friendly and operated at a user-defined air flow rate, and the only cost involved is operational (electric energy) and maintenance (filter replacement). According to the ICA technical team, the filters have to be replaced every 6 months when operating under average conditions such as in a workshop, or every 2-3 months for extremely polluted air. These systems use an integrated flow meter to detect when a significant amount of PM has accumulated on the filters. At that point, an indicator lights up that recommends the user to change the air filter. However, there is currently no sensor on these units that provides information on the air quality in real time for the user to observe the efficiency of the filtration system increasing the air quality over time. Such a feature could also have the user turn off the filtration system when the air is sufficiently clean in order to reduce the operational and maintenance cost, and improve efficiency and life time of the filters. Ideally, one would integrate a VOC sensing system with a filtration unit to provide immediate feedback to the user on real-time air quality. Using two such sensors, one upstream and one downstream from the filter would allow measuring whether the filter is saturated with VOCs, which could occur before accumulation of a significant amount of PM The integration of VOCs sensor to ICA's air filtration systems will give the company a significant competitive advantage over their competitors. ICA would then be the only company that can provide a real-time assessment of air cleanliness as well as their filtration efficiency, as well as a way to turn down the system in order to save energy.
