This analysis demonstrates efficiency in a hybrid supercritical power and refrigeration cycle using various refrigerants, suggesting environmental considerations.
Key Points
The aim is to analyze the thermodynamic performance of a hybrid supercritical power and refrigeration cycle using different refrigerants.
Proposed a hybrid supercritical power and refrigeration cycle.
Analyzed thermodynamic performance with different refrigerants (R1234ze, R600a, R744, R410a, R32).
Conducted first and second law analyses under variable turbine inlet temperature, compressor inlet temperature, flow split ratio, and pressure ratio.
Performed single-objective optimization for system efficiencies.
Conducted Total Equivalent Warming Impact analysis for refrigerants.
Maximum first law efficiency achieved was 0.33.
Maximum second law efficiency achieved was 0.29.
Optimal conditions found at TIT = 301.5°C, CIT = 32°C, FSR = 0.4, PR = 2.9 yielding 0.33 thermal efficiency.
