What’s Next, and How Will It Affect Your Business?
Dr. Rajan Rajendran, V.P. of System Innovation Center and Sustainability at Emerson Climate Technologies, Inc. recently presented an E360 Webinar that addressed the details of the EPA’s final refrigerant delisting ruling. With more than 500 industry participants in attendance, the 14th Webinar in Emerson’s E360 Webinar series explored the final rule’s short- and long-term impacts on the commercial refrigeration industry. As a nationally recognized expert in refrigerants, Rajan began by demonstrating the global trend toward lower global warming potential (GWP) refrigerants — particularly noting the European Union’s target of phasing down to sub-150 GWP refrigerants in commercial refrigeration applications by 2022.Read more
Table 1: How R744 meets different conditions and criteria
Multiple factors need to be carefully considered when selecting any refrigerant, including its cooling capacity, safety, environmental impact, ease of use, cost, and availability of components and expertise. Table 1 summarizes these and other key criteria, and shows how well R744 meets them.
In general, the table shows that R744 offers a more superior cooling capacity than conventional refrigerants while meeting the demand for a natural refrigerant with low global warming impact, but presents challenges in both its application and handling.
In the next post, we’ll look at the properties of R744 as a naturally occurring substance.

AHRI has posted nine final test reports for its Low Global Warming Potential Alternative Refrigerants Evaluation Program (Low-GWP AREP). The reports contain drop-in test results of low-GWP refrigerants in several different types of systems:
Commercial ice machines
Residential heat pumps
This Low-GWP AREP was started over two years ago. The alternative refrigerants are not ranked, however. The goal of the program was simply to identify potential refrigerant replacements for high GWP refrigerants (such as R404A, R134a, and R410A) and present performance of these replacements in a consistent and standard manner.
