52. VRF Systems in an A2L World

Join ASHRAE Journal's Linda Rathke and Allison Hambrick live from the AHR Expo with Women in ASHRAE Leadership Symposium co-chairs Nancy Kohout and Karine Leblanc for a discussion about leadership in STEM—where emotional intelligence, communication and human connection matter just as much as technical expertise.

Join host Justin Seter, along with guests David Quirk and Dustin Demetriou, live from the 2026 AHR Expo for all the latest on liquid cooling in data centers, including rapid IT advancements, the need for quality and speed in the evolving tech landscape, and industry-wide updates on best practices. 

Join Alex and Colin McQuade for a lively interview with their father, 2025-2026 ASHRAE President Bill McQuade, about his career in the HVAC&R industry, this term’s ASHRAE Society theme “Healthy Buildings: Designing for Life,” and how to be an effective leader.

Join host Badri Patel along with guests Fernando Dutra Del Castillo, Kimberly Pierson and Patricia Young as they discuss the process behind ASHRAE certifications and the value of these certifications in advancing careers and setting industry standards in the HVAC industry.

Join ASHRAE Journal assistant editor Allison Hambrick and Max Rohr, Member ASHRAE, as they discuss zero energy buildings, biomimicry and designing for energy efficiency.

Join host Jamie Kono, P.E., Associate Member ASHRAE, along with guests Robert Hart, P.E., and Laura Van Rietema, P.E., Associate Member ASHRAE, as they discuss the impact retrofitting windows can have on energy efficiency in commercial buildings, using One Maritime Plaza as a case study.

Join host Badri Patel, P.Eng., Member ASHRAE, along with industry veterans Christopher Williams, Member ASHRAE, and Scott McGinnis, P.E., Member ASHRAE, as they explore the impact of A2L refrigerants, ASHRAE Standard 15 and its implications, the future of VRF technology, and how ASHRAE members can get involved in the conversation surrounding refrigerants. 

Join ASHRAE Journal Assistant Editor Allison Hambrick and guest Gursaran Mathur, Ph.D., P.E., Fellow/Life Member ASHRAE, as they discuss the circulation and management of carbon dioxide (CO2) in automotive vehicles, and how high levels of CO2 concentrations that can impact the safety and health of vehicle occupants can be controlled.

Join ASHRAE Journal Editor Drew Champlin as he interviews Max Sherman, Ph.D., Fellow/Life Member ASHRAE, about his award-winning article "IAQ Paradigms—The Next Generation.”  The conversation delves into the evolution of IAQ paradigms from ancient ventilation practices to modern standards, the role of ASHRAE in setting these standards, and the current paradigm shift focused on controlling infectious aerosols.

Join host Justin Seter, Associate Member ASHRAE, along with guests David Quirk, Member ASHRAE, Tom Davidson, Member ASHRAE, and Dustin Demetriou, Member ASHRAE, as they provide an update on the state of liquid cooling in data centers. Topics of discussion include research on liquid cooling resiliency, S classes and their importance, and standardization as it pertains to the rapidly evolving data center industry.
