Thermodynamic performance of eight zeotropic R-22 alternative refrigerant mixtures selected by AREP(R-22 Alternative Refrigerants Evaluation Program) and R-32/R-125/R-134a (23%/25%/52%), namely R-407C, were evaluated by the “drop-in" simulation.
An existing air conditioner was selected and its design data were used for the simulation under the “ARI Test A" air conditions. The degree of vapor superheat at the compressor inlet is fixed at 5℃ for all the mixtures. The results of the simulation were compared with those of R-22.
COPs of all mixtures, except for R-32/R-227ea(35%/65%) and R-32/R-125/R-134a (10%/70%/20%), were higher than that of R-22 by 2%~8%, while the capacities were lower than that of R-22 by 13%~27%.
COP of R-32/R-134a(40%/60%) was 2.4% higher but the capacity was 15% lower than those of R-22. In the case of R-32/R-134a(30%/70%), COP and capacity were 5.5% higher and 15% lower than those of R-22, respectively.
Among the ternary mixtures, R-407C and R-32/R-125/R-134a(30%/10%/60%) showed the best performances. COP of R-407C was 2.7% higher than that of R-22 but the capacity was 19% lower.
