Lower GWP Alternatives for R-404A in Commercial and Transport Refrigeration

Track: Refrigeration

Room: Grand Ballroom C

Sponsor: 10.07 Commercial Food and Beverage Cooling Display and Storage, TC 10.06, TC 03.01 and MTG LowGWP

Chair: Brian Fricke, Ph.D., Member, Oak Ridge National Laboratory, Oak Ridge, TN

When commercial and transport refrigeration systems began shifting away from HCFC refrigerants to HFC refrigerants, R-404A became the refrigerant of choice and the industry standard HFC. However, with an extremely high GWP, there is now an industry-wide demand for R-404A replacement refrigerants, driven by recent and proposed changes in regulations, such as the EU F-Gas Regulations and EPA SNAP. Beyond suitable replacement refrigerants, there is a need to understand how these new refrigerants will behave in existing systems and what changes will be required in design practice, construction and commissioning for all systems. This seminar presents experimental results for new lower GWP refrigerant alternatives and discusses how characteristics such as temperature glide and mild flammability may be managed.

1. Challenges in Retrofitting R-404A with Lower GWP Refrigerants

New Refrigerants and Analytics for Refrigeration

Track: Refrigeration

Room: Grand Ballroom C

Some of the greatest advancements in our industry continue to be in refrigerants, particularly with regard to global warming potential. These presentations cover regulatory actions, modeling of household refrigerators, how to achieve safety through management and how to save energy through refrigerant selection.

Retrofit or Not? Life-Cycle Strategy for Systems with R-22 and High-GWP Refrigerants

Track: Refrigeration

Room: Grand Ballroom C

Sponsor: Refrigeration Committee, TC3.1, TC8.01, 10.07 Commercial Food and Beverage Cooling Display and Storage

Chair: Georgi S. Kazachki, Ph.D., Fellow ASHRAE, Dayton Phoenix Group, Inc., Dayton, OH

The approaching deadline for discontinuing R-22 production creates anxiety among end-users of refrigeration and air-conditioning equipment about relevant actions they need to take. The presentations on R-22 alternatives do not emphasize that no regulation mandates R-22 replacement in existing units. This seminar will introduce the most recent information on R-22 and other high-GWP alternatives and will clarify that as long as the refrigerant in the system or unit doesn't leak, it can be there for the life of the equipment and that the decision on refrigerant retrofit or a new system has to be based on a life-cycle cost analysis.

1. Volatility and the Hidden Business Risk

Jason Robbins, P.E., Member, Walgreens, Inc., Deerfield, IL

2. R22 and R404A Servicing Options: Service, Retrofit, or Replace

Brett Van Horn, Ph.D., Member, ARKEMA, King of Prussia, PA

3. Retrofit or Not? Decision Making for R-22 Systems

Robert W. Yost, Member, National Refrigerants, Rosenhayen, NJ

4. Evaluations of R22 Replacements for Refrigeration and Air Conditioning

Samuel Yana Motta, P.Eng., Member, Honeywell - Buffalo Research Laboratory, Buffalo, NY
