SYSTEM FOR HEATING AND COOLING A SEAT AND SEAT ASSEMBLIES

A system for heating and cooling a passenger seat utilizing a single unit for producing hot and cold conditioned air. The system includes a source of pressurized air, a vortex tube adapted to be coupled to the source of pressurized air for producing hot and cold airstreams, a duct network coupled to the vortex tube through a valve assembly, and a controller controlling passage of the flow of hot and cold air streams through the manifold assembly based on passenger selection. Conditioned air flow can be dispersed into a cushion assembly such as an interior of a spacer mesh component of the cushion assembly.
