Summary

THERMOPHYSICAL PROPERTIES OF R124A AND R134A ARE CALCULATED FROM THE RKS EQUATION. MANY OF THESE DATA WERE PREVIOUSLY UNKNOWN AND SHOW GOOD CORRELATION WITH PUBLISHED DATA. FROM A COMPARISON OF THERMODYNAMIC PERFORMANCES OF R114-R124A AND R12-R134A IT APPEARS: FOR A 243/303 K (-30/30 DEG C) CYCLE A LOSS OF 16% FOR REFRIGERATING CAPACITY AND A LOSS OF 14% FOR COP IN THE CASE OF R134A ; FOR A 303/363 K (30/90 DEG C) CYCLE A GAIN OF 68% FOR THERMAL CAPACITY AND A LOSS OF 9.7% FOR COP IN THE CASE OF R124A.
