A Study on the Refrigerant Performance Characteristics of a Refrigeration Cycle to Reduce Greenhouse Gases

Many countries are trying to figure out the development of friendly refrigerant according as recently environment contamination and global warming are becoming a main international issue. As CFC-12 refrigerant having been used for a long time is prohibited, R-134a, alternative refrigerant, which the index Ozone Depletion Potential, ODT is nearing zero has widely been used, but R-134a is regulated by Kyoto protocol because its GWP(Global Warming Potential) comes to 1300. Accordingly, the study shows the result of experimental comparison with characteristics between outdoor air temperature and compressor speed change by using aircondition system to know the usefulness probability of OS12a alternating R-134a.
