Review of ultra-low GWP molecules – thermodynamics properties and their characteristics for use in HVAC&R.
Number: 1118
Author(s) : KUJAK S., SCHULTZ K., SORENSON E.
Summary
This paper provides a review of current, proposed and potential future molecules with ultra-low GWP suitable for use as refrigerants in vapor compression (e.g., HVAC&R) or expansion (e.g., ORC) applications. A summary of thermodynamic properties and cycle performance, along with flammability, stability, and toxicological properties is provided for a variety of single molecules (in pure form), including descriptions of potential application areas.
This paper summarizes information on the olefin-based refrigerants currently in use, such as R-1130(E), R-1336mzz(Z), R-1233zd(E), R-1234ze(E), and R-1234yf. It also includes several “new” molecules recently brought forward to serve as potential low GWP refrigerants by themselves or as components to create new low GWP refrigerant blends. These include R-1224yd(Z), R-1336mzz(E), R-1123, R-13I1 (CF₃I) and R-1132a. In addition, potential future molecules suggested by McLinden (2017) are reviewed, such as R-1132(E) and trifluoropropyne.
