System for increasing supercritical Brayton cycle efficiency through shift of critical point using gas mixture

摘要

PURPOSE: A system for improving the efficiency of a supercritical brayton cycle through the movement of a critical point using gas mixture is provided to improve the efficiency of a thermodynamic cycle by changing the operation temperature and pressure of the thermodynamic cycle. CONSTITUTION: A system for improving the efficiency of a supercritical brayton cycle through the movement of a critical point using gas mixture is composed as follows. A closed circuit is formed by connecting a heating source(1), a generation turbine(2), a heat regenerator(3), a cooler(4), and a compressor(5) to a connection line. Working fluid, which is produced by mixing carbon dioxide with helium, circulates in the closed circuit.
