THE R134A ENERGY EFFICIENCY PROBLEM: FACT OR FICTION.

Summary

THE PAPER EXAMINES THE CONTROVERSY OVER THE RELATIVE ENERGY EFFICIENCIES OF R134A AND R12, FROM A THEORETICAL THERMODYNAMIC PERSPECTIVE. THE AUTHORS HAVE USED AN IN-HOUSE PROCESS FLOWSHEETING PROGRAM ALLOWING TO SIMULATE THE COMPLETE THERMODYNAMIC CYCLE, AND TO INVESTIGATE THE EFFECTS OF SUPERHEAT AND SUBCOOLING. MODELLING EXPERIMENTS DEMONSTRATE THE RELATIVE EXTENTS TO WHICH R12 AND R134A RESPOND DIFFER-ENTLY TO SUPERHEAT AND SUBCOOLING. WITH APPROPRIATE SUPERHEAT AND SUBCOOLING, R134A CAN PROVIDE COP VALUES ESSENTIALLY EQUIVALENT TO THAT OF R12.
