Identifying and Evaluating Alternatives to CFC-114 for Navy Shipboard Chillers

摘要

The isomers HFC-236ea (1,1,1,2,3, 3-hexafluoropropane) and HFC-236fa (1,1,1,3,3,3-hexafluoropro-pane) are potential non-ozone depleting replacements for CFC-114 (1,1,2,2-tetrafluorodichoroethane); and have completed preliminary toxicity evaluations, flammability tests, material compatibility tests, and engineering performance tests. Many parties (e.g., chemical manufacturers, toxicity testing laboratories, chiller manufacturers, government, and national laboratories) have played a significant role in assisting in developing CFC-114 alternatives to replace CFC-114 in retrofitted Navy shipboard chillers.
