Event Information
AHRTI Flammable Refrigerants Research & Planning Conference
Date: October 8 — 9, 2018
Location: UL


Registration must be made online. On-site registration will not be available. Seating is limited to 150 attendees. Registration will be closed when the limit is reached.



This two-day event will focus on the findings of the AHRI-led flammable refrigerant research, which has been ongoing since 2016, following AHRI’s years-long low-GWP refrigerant research. The meeting will feature presentations on research projects, including the most recent flammable refrigerant testing results, and will allow time for attendees and presenters to discuss a path forward regarding necessary updates to safety standards and codes resulting from the research, as well as future research. The conference will cover the following subjects. 


•             Relevant standards and codes

•             Whole room scale testing

•             Refrigerant charge limit and leak rate characterization

•             Component testing


In anticipation of a global plan to phase down high-GWP refrigerants, the industry researched and identified potential alternatives, many of which are low toxicity and low-GWP, but are classified as mildly flammable or flammable. AHRI, ASHRAE, the California Air Resources Board, and the U.S. Department of Energy initiated a $5.6 million research program to develop the technical knowledge needed to facilitate and accelerate the safe use of flammable refrigerants for the industry, as well as for the standards and codes communities.


Join us October 8-9 at UL in Northbrook, Ill., to review the results of the program as well as additional results outside the program, and participate in a discussion of how the results could change and impact relevant standards and codes.



Who Should Attend


Technical experts who are/will be working with flammable refrigerants and individuals who are involved in products and applications, safety standards, and codes.

Regulators who work on refrigerant regulations.





$100 registration fee includes attendance at all technical sessions, lunch, and breaks.


Registration for the AHRTI Flammable Refrigerants Research & Planning Conference will close on Sunday, September 30.


Registration Cancellation


Cancellations will incur a $25 administrative fee. Refunds will be provided, less the $25 fee, if AHRI receives notice of cancellation via email to knord@ahrinet.org by September 30, 2018. After September 30, 2018, no refunds will be given; however, attendee substitutions will be allowed. Contact Katie Nord at knord@ahrinet.org.
