PCT No. PCT/JP85/00139 Sec. 371 Date Nov. 21, 1985 Sec. 102(e) Date Nov. 21, 1985 PCT Filed Mar. 22, 1985 PCT Pub. No. WO85/04465 PCT Pub. Date Oct. 10, 1985.A reversed Rankine cycle system, wherein a vortex tube is disposed between the compressor and the condenser in a reversed Rankine cycle, the superheated vapors of coolant at a high pressure discharged from the compressor are taken out while separating them by the vortex tube into higher and lower temperature components through energy separation to render most of the portion thereof into superheated vapors of coolant at a higher temperature and the remaining portions into vapors of coolant at a lower temperature respectively, and the superheated vapors of coolant separated to the higher temperature side are introduced into the circuit on the higher temperature side of the condenser and condensated therein, while the vapors of coolant separated to the lower temperature side are recycled to the system, of the cycle, preferably, to the circuit on the lower temperature side of the condenser. Heat may be supplied from the atmospheric air or from the compressor to the vapors of coolant from the lower temperature side of the vortex tube or, in the case where the temperature of the coolant on the lower temperature side is high, excess heat may be recovered therefrom by a heat exchanger for heat absorption. |
