Claim Text:
1. An air treatment system for a vehicle comprising: a refrigerant compressor selectively coupled to a power source of an associated vehicle; a first heat exchanger communicating with an interior space defined in the associated vehicle; a second heat exchanger communicating with an environment exterior to the associated vehicle; a valve assembly which, in a first setting, couples an inlet of the refrigerant compressor to an outlet of the first heat exchanger and an outlet of the refrigerant compressor to an inlet of the second heat exchanger, and, in a second setting, couples the outlet of the refrigerant compressor to an inlet of the first heat exchanger and the inlet of the refrigerant compressor to an outlet of the second heat exchanger; and a nuclear-biological-chemical (NBC) filtration unit secured to the associated vehicle, the unit including a blower, an inlet in fluid communication with air exterior to the associated vehicle, an outlet in fluid communication with air in the interior space of the associated vehicle and an NBC filter positioned in a fluid flow path between the inlet and the outlet of the NBC filtration unit wherein the NBC filter comprises a reverse airflow regenerative filter, wherein the filter is heated during regeneration, and further including a pre-filter heat exchanger.
