Retrofitting vehicles with R134a: a global perspective.

Author(s) : COLMERY S. H., LINDLEY A. A.

Summary

The most recent information suggests that the technical barriers to R134a retrofit have been substantially reduced. With proper attention to recovery and evacuation procedures, residual R12 can be controlled to levels at which their effects are minimal. Further, materials compatibility research using laboratory and vehicle fleet studies shows that most original equipment manufacturer hoses, elastomers, and gaskets can effectively contain R134a under demanding use scenarios. Studies have also indicated that existing desiccants can be used without catastrophic failures in retrofitted R134a systems and in some parts of the world existing R12 desiccants have been used extensively with R134a retrofitted systems.
