摘要： 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 O3 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.

摘要： An aircraft environmental control system includes a catalytic converter having ozone-destroying capability. A surface of the catalytic converter is anodized to form an anodized layer, and the metal oxide layer is washcoated to form a washcoat layer. An ozone destroying catalyst is impregnated in the anodized and washcoat layers. The catalyst may include one or more metals. For example, a bimetallic catalyst may include a precious metal and a transition metal.
