An isothermal turbo-compressor-condenser-expander arrangement includes heat-transferring blades that are mounted on, or surround, individual conduits. In operation, the open framework rotates in free air to promote heat exchange. The assembly includes a first plurality of spokes extending radially outwardly from a first central hub to an outer perimeter with first radial conduits that transport refrigerant under centrifugal force and compression from the hub to the outer perimeter. The first radial conduits include heat exchanging blades. A second plurality of spokes extend radially outwardly from a second central hub that each includes a second thermally-insulated conduit that transports refrigerant from the outer perimeter to the second central hub. Axial conduits extend axially at the outer perimeter. At least some of the axial conduits include an axial blade in thermal communication with the conduit.

Turbo-compressor-condenser-expander

A turbo-compressor-condenser-expander arrangement, including heat-transferring blades mounted on or surrounding individual conduits. The open framework rotates in free air to promote heat exchange. A first hub, a first set of radial conduits, axial conduits, a second set of radial conduits, and a second hub are included; a motor rotates a central axis of the turbo-compressor-condenser-expander.
