A high-efficient heat cycle device formed by combining a heat engine (A) with a refrigerating machine (J), wherein steam (Eg) generated in a boiler (B) is cooled by a condenser (Y<SUB>1</SUB>) after driving turbine (S<SUB>2</SUB>), built up by a pump (P<SUB>2</SUB>), and circulated into the boiler (B) in the form of high-pressure condensate. Refrigerant gas (Fg) compressed by a compressor (C) is passed through the radiating side of a heat exchanger ( 7 ) for cooling after driving the turbine (S) to output a work (W<SUB>1</SUB>), and built up by a pump (P<SUB>1</SUB>) to form high-pressure refrigerant liquid. The high-pressure refrigerant liquid drives a reaction water-turbine (K) to output a work (W<SUB>2</SUB>) and is expanded and vaporized to form refrigerant gas. The refrigerant gas is led into the compressor (C) after being passed through the heat absorbing side of the heat exchanger ( 7 ) and the condenser (Y<SUB>1</SUB>) for heating.
