COOLING TURBINE Russian patent published in 2005 - IPC

FIELD: cooling and heating equipment; devices used for cooling and heating atmospheric air fed to domestic or industrial rooms.

SUBSTANCE: proposed cooling turbine includes casing, centrifugal multi-stage compressor, multi-stage peripheral-admission turbine whose blades are located between cover shields provided with circular projections over periphery and cover disks. Centrifugal compressor is provided with straightening apparatus at its inlet which has spiral blades with intake holes over periphery of rotor. Multi-stage peripheral-admission turbine is provided with outlet apparatus at its inlet which has spiral blades with outlet holes over periphery of rotor; rotor is mounted on revolving shaft. Working blades are secured on cover shields of rotor. Located in initial row of immovable disks as far as middle one are immovable straightening apparatus with spiral blades of diffuser which are located on fixed axle inside rotor. Located in subsequent row of immovable disks, after middle one, are immovable nozzle sets provided with spiral blades of contraction and secured on fixed axle inside rotor. Middle dividing disk is non-rotating and is rigidly secured on the same axle inside rotor. Rotating blades located on opposite sides of dividing disk are also secured on cover shields of rotor. Fixed axle has hole for passage of additional cooler or heater. On side of drive unit, end tenon of rotor is located between two bearings.

EFFECT: enhanced efficiency under any climatic conditions.
