R123 has been used successfully as a low ODP replacement for R11 since the ban on R11’s production after December 31, 1995, imposed by the Montreal Protocol. However, the Montreal Protocol ban on use of R123 after December 31, 2019, in developed countries is becoming imminent. This paper provides a description of the environmental and thermodynamic characteristics of R514A as a replacement for R123. The thermodynamic properties of R514A result in comparable performance to R123. The performance of two centrifugal compressor-based chillers was measured in laboratory tests with R123 as a baseline and with R514A as a replacement.
