Résumé

This paper will focus on the developments of new molecules that have low global warming potential, high thermal performance, and favorable safety characteristics, to name only a few required characteristics. Several new molecules that have very short atmospheric lifetimes, as well as refrigerant blends utilizing these molecules, have been developed and will be evaluated for use in various types of water chillers ranging from smaller capacity systems that currently use R-410A or R-407C refrigerants to larger centrifugal compressor chillers that have currently used R-134a or R-123. Thermodynamic and system simulations were carried out using low GWP refrigerant properties and compared against the baseline refrigerants. These new LGWP refrigerants show promise in these applications and warrants further development.
