An environmental control system having an ozone decomposition catalyst coating in the hot pass side of the primary heat exchanger. The environmental control system includes primary and secondary heat exchangers as well as a rotary compressor and a rotary turbine expander. The environmental control system is used in aircraft for providing conditioned air to the habitable space of the aircraft for life support purposes.

In a vehicular environmental control system for conditioning a relative warm airflow for subsequent delivery to a habitable space within the vehicle: an inlet duct for receiving the relatively warm airflow; a primary heat exchanger having a hot pass core and a cool pass core, each of said cores comprising a plurality of elements respectively defining hot pass and cool pass passageways, said elements of said hot pass and cool pass cores being in heat exchange relationship, said heat exchanger arranged such that the relatively warm airflow from said inlet duct passes through said hot pass passageways, said heat exchanger adapted to receive a flow of relatively cool fluid flow through said cool pass passageways; an ozone decomposition catalyst coating on the surfaces of said elements of the hot pass core exposed to said hot pass passageways, said coating effective to decompose ozone in said warm airflow; a rotary compressor disposed to receive airflow exhausted from said hot pass passageways of the heat exchanger and operable to compress the airflow; a rotary turbine expander driven by the compressed airflow for expanding and cooling the compressed airflow, said turbine operably coupled to drive said compressor; and a secondary heat exchanger disposed between said compressor and said turbine for removing at least a portion of the heat of compression in the airflow, said secondary heat exchanger adapted to receive a flow of cooling fluid to provide a heat sink for removal of said portion of heat.
