Abstract
A compact energy cycle construction that operates as or in accordance with a Rankine, Organic Rankine, Heat Pump, or Combined Organic Rankine and Heat Pump Cycle, comprising a compact housing of a generally cylindrical form with some combination of a scroll type expander, pump, and compressor disposed therein to share a common shaft with a motor or generator and to form an integrated system, with the working fluid of the system circulating within the housing as a torus along the common shaft and toroidally within the housing as the system operates.
Claims20
A compact energy cycle construction that utilizes a working fluid in its operation, comprising:
- a housing of a generally cylindrical form,
- a plurality of energy cycle devices disposed within the housing and interconnected to form an integrated system operable in accordance with an energy cycle, at least two of the plurality of energy cycle devices sharing a rotatable common shaft, the system effecting circulation of the working fluid in a torus within the housing as the system operates;
- a central passageway extending through the common shaft, the central passageway facilitating working fluid transit through the common shaft;
- and
- a heat transfer portion that employs a heat transfer fluid during its operation, the heat transfer portion disposed along the common shaft and comprising:
- a heat transfer fluid conduit spirally wrapped about the common shaft, the conduit spaced outwardly from the common shaft to define a space therebetween and having a fluid inlet and a fluid outlet;
- and
- heat transfer fins disposed along the common shaft and the conduit in the space therebetween,
- wherein the plurality of energy cycle devices includes a scroll compressor, a motor, and an expander, all sharing the common shaft.
