Abstract: A self contained air conditioned seat to control the temperature climate in an air bubble generated around the seat occupant is described. It includes an air bubble at a controlled temperature for the upper body and seat of the occupant, a separate air bubble for the legs of the occupant and a controller which allows the occupant to have personal control of the temperature in the two zones. Temperature sensors are located in one or more of the tips of the arm rests, the heat rest, beneath the seat bottom and in the return air ducts, to help maintain the air bubble temperature in the two zones.

Abstract: An air-conditioning unit is positionable through a partition such as a wall. The unit has a housing passing through the wall and a plate covering the inner end of the housing. The evaporator coil is mounted on the plate. A further plate extends from the plate horizontally into the housing and the compressor and condenser are mounted on the further plate. An aperture leads through the first mentioned plate for the passage of air and leads to an elongated duct to provide sound attenuation. Sealing gaskets are provided between the housing and the first mentioned plate and sound deadening material is positioned to deaden sound on the housing and the first mentioned plate.
