    • An air treatment system includes a filter and heating element, a plasma device, and a photocatalyst and UV light that cooperate to purify an air stream flowing through the air treatment system and protect the photocatalyst from passivating effects of certain contaminants. The air treatment system operates in two different modes. In the first mode, the air treatment system primarily draws air from and returns air to a space, and the heating element and plasma device are selectively shut off. In the second mode, the air treatment system regenerates the filter using the heating element to selectively heat the filter and release adsorbed contaminants. The plasma device is selectively turned on and chemically transforms the released contaminants into solid contaminant products. The solid contaminant products are deposited on a biased electrode of the plasma device. The UV light is turned off to ensure that the photocatalyst is inoperable during the release and transformation of the contaminants. Once deposited, the essentially immobile and inert solid contaminant products are unlikely to damage the photocatalyst.
    • 空气处理系统包括过滤器和加热元件,等离子体装置和光催化剂和UV光,其协作以净化流过空气处理系统的空气流并保护光催化剂免受某些污染物的钝化作用。 空气处理系统以两种不同的方式运行。 在第一模式中,空气处理系统主要从空气中抽取空气并将空气返回到空间,并且选择性地切断加热元件和等离子体装置。 在第二模式中,空气处理系统使用加热元件再生过滤器,以选择性地加热过滤器并释放吸附的污染物。 选择性地打开等离子体装置,并将释放的污染物化学转化成固体污染物。 固体污染产物沉积在等离子体装置的偏置电极上。 UV灯被关闭,以确保在污染物的释放和转化过程中光催化剂不可操作。 一旦沉积,基本上不可移动和惰性的固体污染物产物不可能损坏光催化剂。
