MAKING SENSE of New Refrigerants

Today, the refrigeration industry is in the throes of transition. As governments around the globe look at curtailing the use of refrigerants with high global warming potential (GWP), retail refrigeration operators and equipment manufacturers are anticipating the next generation of refrigeration system architecture. In response to these increasing regulations, many equipment manufacturers are actively developing refrigeration systems based on natural refrigerants such as ammonia, propane and CO2. While these natural alternatives promise significantly lower GWP compared to current HFC-based systems, they will require operators to update system architectures and service practices to accommodate their unique temperature and pressure requirements.

And in case you’re of the opinion that these impending regulations are a far-off future event, think again. In Europe, the parliament recently unanimously passed a vote in favor of new legislation that will significantly reduce fluorinated gas (F-gas) in new commercial refrigeration equipment by 2020. In the United States, the Environmental Protection Agency’s (EPA) Clean Air Act placed the reduction of HFC refrigerants directly in its sights, with promises of new regulations that reduce HFC use as soon as the summer of 2014.

Our next Making Sense webinar will explore the implications of these new refrigerants on system architecture, equipment selection and service. Some larger supermarket refrigeration systems in North America have already begun the transition to natural refrigerants, especially with the use of CO2-based transcritical systems that perform well in colder climates. But for other operators, in particular smaller retailers, this transition poses more questions than answers. That’s precisely the reason we’re offering this complimentary webinar.

In this complimentary webinar, you’ll learn:

  • Background on new alternative and natural refrigerants
  • Why propane and ammonia are gaining popularity
  • Differences between CO2 and HFCs
  • Three system architectures that utilize natural refrigerants

The webinar will be presented by Andre Patenaude, Director — CO2 Business Development, Emerson Climate Technologies. Andre’s extensive experience with various refrigeration system architectures and alternative, emerging refrigerant technologies makes him well-suited to lead this discussion. He’s currently responsible for developing a global strategy that incorporates the company’s CO2 industry stewardship, marketing initiatives, communication/messaging activities, channel training and educational programs as they relate to utilizing CO2 in refrigeration systems.
