Abstract: PURPOSE: A heat engine based on a transcritical rankine cycle with improved exergy efficiency and a method thereof are provided to improve exergy efficiency by heat-exchanging a compacted working fluid with a low grade heat source by compressing a working fluid which is condensed and cooled by condensing and cooling a working fluid flowed out from a turbine. CONSTITUTION: A heat engine method based on a transcritical rankine cycle with improved exergy efficiency comprises the following steps: a working fluid flowed out from a turbine(10) is condensed and cooled; a condensed and cooled working fluid is compressed; a compacted working fluid is heat-exchanged with a low grade heat source; before a working fluid flowed out from the turbine is condensed and cooled, heat-exchanging with a working fluid passing through a first thermal exchange stage; and a working fluid passing through a first thermal exchange stage and a second thermal exchange stage is flowed into the turbine.

Abstract: A compressed air storage generating system and a power generating method using the same are provided to keep uniform pressure of discharging air from a storage tank by constituting multiple storage tanks, connecting lower parts of the tanks with each other, and containing water in the tanks. A compressed air storage generating system includes a compressor(20) inhaling and compressing outside air by operation of a motor, a storage tank storing the compressed air, a combustion device(50) burning fuel mixed with the compressed air supplied from the storage tank, a turbine(40) operated by the burned gas, and a generator operated by the turbine. The storage tank, a first storage tank(31) and a second storage tank(32), are connected to each other through a connecting pipe(33). An intake port(311) and a discharge port(312) are formed on a top of the first storage tank to inhale the compressed air from the compressor and to discharge the compressed air in the storage tank. Storage water(34) fills lower parts of the first and the second storage tank to seal the second storage tank hermetically to be used as a pressurizing device.
