ABSTRACT:
A high-efficiency heat cycle system including a compressor, a first turbine, first and second heat exchangers7and8, a first pump, and an expander, and a composite heat cycle power generator using the high-efficiency heat cycle system. Working gas Fg compressed in the compressor (C) drives a first turbine (S) and is thereafter cooled by passing through a heat dissipating side of a first heat exchanger (7) and then raised in pressure by a first pump (P) to form high-pressure working liquid Fe, the high-pressure working liquid is expanded and evaporated in an expander (K) to form working gas Fg, said working gas Fg is heated by passing through a heat receiving side82of the second heat exchanger before being introduced into the compressor C. A heat dissipating side81of the second heat exchanger comprises a heat dissipating portion of a refrigerating machine or a heat dissipating portion for waste heat from a heating machine.
