Abstract: An air purification system for a heating, ventilation, and air conditioning (HVAC) system includes an ozone generating device that is used to introduce ozone into an air stream flowing through the ozone generating device. The ozone is used to remove contaminants, including volatile organic compounds (VOCs), from the air stream. The purification system includes sensors in various locations within the HVAC system to measure a concentration of constituents in the air. In some embodiments, the constituents may include ozone and VOCs, such as toluene, butene, and propanal. To control an amount of ozone generated, the purification system controls an amount of electrical power to the ozone generating device. To control a concentration of ozone generated, the purification system controls a flow rate of air through the ozone generating device.

Abstract: A contaminated gas that is to be cleaned, such as contaminated air, is passed through an adsorbent bed to remove gaseous contaminants. An enclosure having a fixed volume is then created around the adsorbent bed. Included within the enclosure is a photocatalytic gas purifier. The adsorbent bed is heated to release the contaminants into the fixed volume to create a high concentration of contaminants in the gas within the fixed volume. The now highly contaminated fixed volume of gas is recirculated through the heated adsorbent bed and photocatalytic gas purifier. The gas purifier oxidizes the contaminants at a high oxidation rate due to the high contaminant concentration level. The enclosure is then opened and the adsorbent bed, now regenerated and at its original temperature, is ready to again receive and clean contaminated gas.

Abstract: A photocatalyst system for volatile organic compounds with two parts that include a photocatalyst layer on a substrate and a porous overlayer. The photocatalyst layer is reactive with volatile organic compounds when UV light is projected on it. The overlayer is situated on the photocatalyst layer. The overlayer is UV transparent and has an interconnected pore network that allows contaminated air to pass through the overlayer. The size and the shape of the interconnected pores acts to selectively exclude certain contaminants that can deactivate the photocatalyst.
