Abstract
An air cleaning system and method employs both particulate and gaseous contaminant removal from a flowing air stream to improve air quality in a selected environmental space. Particulate contaminants are removed by an appropriate filter. Gaseous contaminants such as VOCs, CO, and O are removed using a catalyst to oxidize such contaminants. The air stream is selectively heated to provide an adequate catalyst reaction temperature and the heat energy is then recovered by a heat exchanger. Various sensors are employed to monitor flow rate, air composition, temperature and pressure. A controller is programmable to control air quality for either minimizing contaminants or minimizing energy usage required to achieve a selected minimum air quality over a period of time.
