ABSTRACT:
The thermodynamic compressor has a pair of conduits, each of which is wound into a group of loops arranged to form a toroid around a rotational drive axis. Each of the loops has an outwardly-extending section, and an inwardly-extending section which is spaced from the outwardly-extending section longitudinally along the rotational axis of the shaft. Each group of loops has the same number of loops in it, and corresponding loops in each of the groups are arranged directly opposite one another and working fluid is introduced in parallel into the groups of loops so that the amount of fluid in each pair of corresponding opposed loops remains the same at all times despite compression of the working fluid in the loops. The loops are arranged with the outwardly-extending sections in one plane, and the inwardly-extending sections in another plane so that heat easily can be added from the outside to the inwardly-extending sections and can be extracted easily from the outwardly-extending sections. The compressor is rotated, and each of the groups of loops forms a cascaded series of thermodynamic compressor sections. The compressor therefore uses centrifugal force to act upon opposing radial columns of working fluid having different densities caused by the heat transfer to and from the compressor, thus providing an extremely effective rotary compressor. The thermodynamic compressor of this divisional patent application is illustrated in FIGS. 12 and 13 of the drawings.
