Vehicle cabin heating cooling and ventilation system

摘要

An air treatment system for a vehicle includes a first compressor selectively coupled to a first vehicle power source. A second compressor is selectively coupled to a second vehicle power source. A first heat exchanger communicates with an interior space in the vehicle. A second heat exchanger communicates with an environment outside the vehicle. A valve member, in a first position, couples an inlet of each of the first and second compressors to an outlet of the first heat exchanger and an outlet of each of the compressors to an inlet of the second heat exchanger. In a second position, the valve member couples the outlets of the compressors to an inlet of the first heat exchanger and the inlets of the compressors to an outlet of the second heat exchanger. A controller selectively actuates at least one of the first and second compressors and the valve member.

主权项

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.
