AHRI Refrigerant Webinar Series

 

Determining Application Limits & Safety Requirements for Low-GWP Flammable Refrigerants

 

 

Mark your calendars and plan to join AHRI for this five-part series on research into low-global warming potential (GWP) flammable refrigerant research.

 


 

Background
Various governments around the world have been regulating hydrofluorocarbon (HFC) refrigerants for decades, and there now is a global treaty in effect – the Kigali Amendment to the Montreal Protocol – that establishes a global phase down structure for the chemicals.

 

 

In anticipation of just such a global agreement, AHRI in 2011 initiated a robust research program to identify suitable alternative refrigerants. Most of those identified have low toxicity, but in some cases have different flammability characteristics than those in use today. In a follow-on research program, AHRI, ASHRAE, and the U.S. Department of Energy have thus far invested nearly $7 million to study the safe use of those alternative refrigerants that are classified as flammable or mildly flammable.

 

Who Should Attend?
AHRI encourages manufacturers, channel partners, policy makers, fire service personnel, and building code and environmental experts to attend to learn the industry’s research experience on the safe use of flammable refrigerants.

Why Register?
Participants will gain an understanding of research related to low-GWP flammable refrigerants in this webinar series, examining research in collaboration with Department of Energy, California Air Resources Board, ASHRAE, AHRI, and others exploring fundamental questions regarding flammability as well as practical issues such as sensor evaluation.

Please plan to participate!


 

Webinar 1: Air Conditioning Applications
Wednesday, September 23, 2020 | 12:00 p.m. – 1:30 p.m.

 

 

AHRI Vice President of Regulatory Affairs Helen Walter-Terrinoni will lead a panel of experts to discuss leak and ignition testing of low-GWP refrigerants in air conditioning equipment under whole room scale conditions, as well as refrigerant leak characteristics in real-life applications.

 


 

Webinar 2: Commercial Refrigeration Applications
Wednesday, September 30, 2020 | 11:00 a.m. – 12:15 p.m.

 

 

This session will discuss IEC/UL Standard 60335-2-89 on refrigerant charge level requirements and will summarize the most recent test results on dispersion and ignition tests of low-GWP refrigerants in commercial refrigeration display cases. The testing has covered A2L and A3 refrigerants, and a comparison of A2L and A3 refrigerants on an equivalent basis for single-door and three-door reach-in coolers.

 

Watch for additional details and registration information the week of September 14.


 

Webinar 3: Understanding Refrigerant Sensors
Wednesday, October 7, 2020 | 11:00 a.m. – 12:15 p.m.

 

 

This session will introduce the flammability risk mitigation concept using refrigerant sensors and will review the major differences in sensor requirements across key safety standards. Researchers will present ongoing efforts to evaluate a number of sensors using different sensing technologies.

 

Watch for additional details and registration information the week of September 21.


 

Webinar 4: Predictive Tools for Refrigerant Behaviors
Wednesday, October 14, 2020 | 11:00 a.m. – 12:00 p.m.

 

 

Scientists with Oak Ridge National Laboratory and the National Institute of Standards and Technology will introduce their modeling tools and will discuss with industry members the tools’ applicability to simulating refrigerant dispersions and predicting the burning velocity of refrigerant blends.

 

Watch for additional details and registration information the week of September 28


 

Webinar 5: Refrigerant Ignition in Open Flame/Hot Surfaces: Has Anything Fundamentally Changed?
Wednesday, October 21, 2020 | 11:00 a.m. – 12:00 p.m.

 

 

This session will report on the ongoing research efforts and existing testing results to understand the implications of exposing fluorinated refrigerants to fire or hot surfaces as well as a comparison of legacy and low-GWP refrigerants relative to heat and gases generated in these events.

 

Watch for additional details and registration information the week of October 5.
