Abstract: A fan assembly includes a fan body, a motor-driven impeller contained within the fan body and arranged to generate an air flow, a nozzle including a nozzle body having an air inlet arranged to receive the air flow from the fan body, and one or more air outlets arranged to emit the airflow from the fan assembly. The fan assembly further includes a nozzle retaining mechanism for releasably retaining the nozzle on the fan body, and a rotation mechanism for rotating the nozzle body relative to the fan body. The nozzle rotation mechanism includes a rotation motor arranged to drive a drive member and a driven member that is arranged to be driven by the drive member to rotate around a rotation axis.

Abstract: A rotor for a compressor system includes a rotor body having a coolant manifold with an inlet runner and a plurality of coolant supply conduits extending from the inlet runner toward an inner heat exchange surface. The coolant supply conduits may have a circumferential and axial distribution, and extend through struts enhancing stiffness in the rotor body.

Abstract: A compressor includes a rotor having an outer compression surface and a plurality of inner heat exchange surfaces. A coolant supply manifold fluidly connects with a coolant inlet in a first axial end of the rotor, and delivers coolant fluid by way of conduits having an axial distribution in the rotor so as to deliver coolant fluid to the heat exchange surfaces. The coolant may be a refrigerant that undergoes a phase change within the rotor.
