Abstract: This invention provides an isothermal turbo-compressor-expander-condenser-evaporator in a single integral arrangement that is suitable for a variety of compact arrangements, such as a window air-conditioner and/or automotive-based unit. This arrangement avoids the use of rotary fluid joints and maintains the entire fluid cycle, including compression, condensation, expansion and evaporation within a single rotating shaft-based structure, with the compressor/condenser section and the expansion/evaporator section separated from each other in separate spaces and/or plena by a rotating, insulated barrier disc and associated seal.

Abstract: An isothermal turbo-compressor-condenser-expander (ITCCE) includes heat-transferring fan blades that are mounted on, or surround, individual conduits to promote air exchange and heat transfer. In operation, the open framework rotates in free air to promote heat exchange. An ITCCE bladed assembly includes a driven central hub assembly with a first fluid coupling. A first inner plenum is in fluid communication with the fluid coupling. A plurality of compressor multiport conduits extend radially, and pass fluid from, the first inner plenum to an outer plenum that acts as an equalizing line. A return path is provided to the fluid coupling from the outer plenum. The conduits can be formed as metal extrusions, including internal ribs that separate a plurality of ports formed therebetween along an entire length of the conduits. The conduits can define an airfoil shape and/or are axially twisted, generating axial airflow. The return path can include return multiport conduits.

Abstract: 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.

Abstract: 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.

Abstract: This invention provides an isothermal turbocompressor and a combined turbo-compressor-condenser-expander arrangement, which includes heat-transferring blades that are mounted on, or surround, individual conduits to promote air exchange and heat transfer. In operation, the open framework rotates in free air to promote heat exchange. This optimizes contact with free air during rotation. 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 at an axial spacing from the first central hub. This second plurality of spokes each includes a second thermally-insulated conduit that transports refrigerant from the outer perimeter to the second central hub.
