HFC-134a is currently used as the refrigerant in automobile air-conditioner, replacing the ozone depleting refrigerant CFC-12. Although HFC-134a has no ozone depletion potential, it has a relatively high global warming potential, approximately 1300 tims that of CO₂, over a 100 year time horizon. Therefore, HFC-134a does not seem to be a perfect alternative refrigerant due to high GWP. For this reason, non-azeotrope refrigerant mixture have been proposed as a long-term and drop-in alternative to HFC-134a in the automobile air-conditioning system which has variable operating conditions with changes in RPM and pressure ratio. In this study, OS-12a of which thermodynamic properties are similar to those of HFC-134a is selected among the mixed refrigerant. HFC- I34a and OS- I2a are examined experimently by the performance test in the same automobile air-conditioning system. |
