This study involved the development of a model for evaluating the potential costs and benefits of ozone control by activated carbon filtration in single-family homes. The modeling effort included the prediction of indoor ozone with and without activated carbon filtration in the HVAC system. As one application, the model was used to predict benefit-to-cost ratios for single-family homes in 12 American cities in five different climate zones. Health benefits were evaluated using disability-adjusted life-years and included city-specific age demographics for each simulation. Costs of commercially available activated carbon filters included capital cost differences when compared to conventional HVAC filters of similar particle removal efficiency, energy penalties due to additional pressure drop, and regional utility rates. The average indoor ozone removal effectiveness ranged from 4 to 20% across the 12 target cities and was largely limited by HVAC system operation time. For the parameters selected in this study, the mean predicted benefit-to-cost ratios for 1-inch filters were >1.0 in 10 of the 12 cities. The benefits of residential activated carbon filters were greatest in cities with high seasonal ozone and HVAC usage, suggesting the importance of targeting such conditions for activated carbon filter applications.
本研究旨在开发一种模型，用于评估在单户住宅中通过活性炭过滤控制臭氧的潜在成本和收益。建模工作包括预测 HVAC 系统中有无活性炭过滤时的室内臭氧情况。作为一种应用，该模型用于预测五个不同气候带的 12 个美国城市中单户住宅的效益成本比。健康效益采用残疾调整生命年来评估，并为每个模拟包含特定城市的年龄人口统计数据。商业上可用的活性炭过滤器的成本包括与具有相似颗粒去除效率的传统 HVAC 过滤器相比的资本成本差异、由于额外压降导致的能源罚款，以及区域公用事业费率。在 12 个目标城市中，平均室内臭氧去除效率在 4%至 20%之间，主要受到 HVAC 系统运行时间的限制。在本研究中选择的参数下，1 英寸过滤器的平均预测效益成本比在 12 个城市中的 10 个城市中大于 1.0。在臭氧和 HVAC 使用季节性较高的城市中，住宅活性炭过滤器的效益最大，这表明针对活性炭过滤器应用的此类条件非常重要。
