R-114: Before its production phaseout in 1995, it was used in positive pressure centrifugal chillers for air conditioning and industrial process cooling, as well as for air conditioning in very high ambient temperature conditions. Its very good chemical stability made it useful in highly corrosive applications, such as for shipboard chillers. Good high temperature stability along with lower vapor pressures made it a good choice for high ambient air conditioning, for example in steel mill cranes. Some applications have converted to R-124.
