    摘要： An air mixing unit suitable for buildings having open spaces. In one embodiment, the air mixing unit may include a centrifugal fan and mounting frame. The fan includes a rotatable body, a drive shaft defining a vertical rotational axis, a plurality of radial blades, a top air inlet, and a bottom air inlet. The fan is operable to draw air through the air inlet openings from axially opposing directions in some embodiments, mix the air, and discharge the mixed air laterally outwards from the fan to the open space. In some embodiments, the air mixing unit may be mounted near the ceiling of the building to temper cooler air drawn from outside with warmer inside room air before discharging the air into the space. A method for mixing and destratifying air within a building is also described.

    摘要： A turbocharger including a turbine wheel having a hub-to-tip ratio of no more than 60% and blades with a high turning angle, a turbine housing forming an inwardly spiraling primary-scroll passageway that significantly converges to produce highly accelerated airflow into the turbine at high circumferential angles, and a two-sided parallel compressor. The compressor and turbine each produce substantially no axial force, allowing the use of minimal axial thrust bearings.
