This paper summarizes an experiment campaign on alternative refrigerant evaluation for R-22 and R-410A mini-split systems. The experimental evaluation was performed according to ANSI/ASHRAE Standard 37 and the performance was rated according to ANSI/AHRI 210-240 standard. The paper presents the relative performance (efficiency and capacity) of the alternative refrigerant compared to the baseline refrigerant at the different operating conditions. The paper ends with concluding remarks about the alternative refrigerants for R-22 and R-410A applications in high ambient temperature regions.
