Comparison of HFC-134a and the Ternary Blend, SUVA MP39, as Replacements for theRefrigerant, CFC-12

摘要

The refrigerant gas CFC-12 has been widely used in Royal Australian Navy (RAN)equipment. With the Montreal protocol phase-out of this and other ozone depleting substances, alternative refrigerant gases must be identified. These replacements would ideally have the same efficiency as CFC-12, cause no health and safety risks and allow changeover to proceed with minimal costs. This paper reviews the attributes of two refrigerant gases, HFC-134a and Suva MP39, which are being considered by the RAN.
