ABSTRACT:
A method is described for providing clean air at desired temperature to an environment. Incoming air possibly contaminated with nuclear biological and chemical contaminants is compressed. The compressed air is cooled in a first heat exchanger. The cooled air from the first heat exchanger is compressed in a secondary compressor. Compressed air from the secondary compressor is cooled in a second heat exchanger. Cooled air from the secondary heat exchanger is directed through a regenerative pressure swing absorption system to provide clean output air with the contaminants removed therefrom. This cleaned air is expanded in a turbine coupled to the secondary compressor, whereby to recover energy from the cleaned air to drive the secondary compressor. The expanded cleaned air from the turbine is utilized to condition air in the environment. The regenerative pressure swing absorption system is purged with air derived from the expanded clean air. This purging air is first warmed by heat exchange either with waste heat derived from the step of compressing the incoming air or by heat exchange with clean air exiting the regenerative pressure swing absorption system.
