An Integrated Comparison for Working Fluids Selection in Both Subcritical and Supercritical ORC

Abstract:

A comparison focusing on the properties and the system performances in working fluids selection for both subcritical and supercritical ORC is proposed. 16 candidates including wet, isentropic and dry fluids are considered. Thermal efficiency, exergy efficiency, Specific net power output and UA value are set as the system performance indicators. Under the premise of working fluids safety and comprehensive consideration of all aspects of system performances, R152a by supercritical ORC is determined by integrated comparison.
