Abstract

The goal of this study was to identify non-flammable, non-toxic, low global-warming-potential (GWP) replacements for HFC-134a in an air-conditioning system that would maintain the energy efficiency and capacity. A prior exhaustive work demonstrated that all single-component refrigerants that could serve—from the performance stand-point—as a replacement for HFC-134a are at least mildly flammable. For this reason, this study undertook an evaluation of refrigerant binary and ternary blends to explore the possibility of formulating a non-flammable blend that would satisfy the requirements of military systems.
