Already listed as acceptable as a foam blowing agent, HFO1336mzz(Z) is determined to be acceptable in new centrifugal chillers, positive displacement chillers and industrial process air conditioning. It has a GWP of about 9.
Another potential replacement for R123 in centrifugal and positive-displacement chillers, R514A is deemed acceptable as a retrofit gas as well as in new equipment.
The EPA has also extended the acceptability of R513A as a substitute for R134a in both new and retrofit retail food refrigeration, refrigerated food processing and dispensing equipment.
Previously listed as an acceptable refrigerant in a number of refrigeration and air conditioning end-uses, the acceptability of CO2 (R744) has also been extended for use in ice skating rinks, centrifugal chillers, positive displacement chillers and industrial process air conditioning.
