摘要： A working fluid consisting essentially of CO 2 , a molecule having a low ratio of specific heats, is expanded by a gas turbine 4. Thus, even if the pressure changes between the inlet side and the outlet side of the gas turbine 4, a temperature drop as a temperature change is suppressed, so that an exhaust gas having a high temperature is obtained. Consequently, the difference between the temperature of the working fluid on the outlet side of a compressor 2 and the temperature of the exhaust gas on the outlet side of the gas turbine 4 is kept so great that a regeneration effect is enhanced, whereby thermal efficiency is increased without a decrease in the output.
