REF-TALK 2: HFOs; will it substitute the HCFC & HFC as long-term solutions?

Over the last few years, technology providers surprised the HVAC&R industry with the development and introduction of fluorinated refrigerants that has low-GWP characteristics close or similar to natural refrigerants. With start in deploying those refrigerants commercially in automobile industry for Vehicles air-conditioning particularly in Europe, people start to wonder if HFOs can also be considered as long-term solutions in different HVAC&R applications other than MAC.

Availability, cost, blend composition considerations and safety are questions being raised lately by the industry to the newly developed HFOs that started to be promoted as alternative for commercial refrigeration and Air-Conditioning applications. Availability of compressors designed for HFOs is another concern that also being raised.

This Webinar will try to shed light on those concerns through presenting feedback from industry and end users worked with HFOs and what are potentials, challenges and expectations associated with its use. The Webinar should allow experts from the field to discuss and seek clarifications directly from the technology providers and end-users.

This Webinar is the second of a series titled “REFTALK” aiming at presenting in depth the new commercially or potentially available refrigerants in different sectors.
The OzonAction Webinar aims at providing a platform to share your expertise engaging with worldwide participants in an informal atmosphere.

Mr. Mark W Spatz, Global Refrigerant Technology Leader, Honeywell’s Fluorine Products
Mark W Spatz is the Global Leader for Refrigerant Technology with Honeywell Fluorine Products and for over twenty years was responsible for assisting the air conditioning and refrigeration industries in the transition to environmentally friendlier refrigerants His extensive background includes nearly forty years of experience in the research, development, and design of refrigeration, cooling, energy, and heat transfer systems. In addition to vapor compression technology, conducted research and development on other technologies such as desiccant cooling, absorption, heat pipe technology, Stirling, and Vuilleumier cycles. Mr. Spatz received a Masters Degree in Mechanical Engineering from Union College and a Bachelor degree from City College NY. He is an active member of ASHRAE and SAE.

Dr. Thomas J. Leck, Sr. Principal Investigator New Refrigerant Development DuPont Fluorochemicals
Thomas Leck has 34 years of R&D and Technical work at the DuPont Laboratories. He has worked in refrigeration, lubricants, fluoropolymers, coatings, and chemical catalysis. He joined the DuPont Refrigerants technology organization in 1991 and worked on technical issues necessary to bring non ozone depleting refrigerants to the commercial markets. For the past seven years he has been working with fluoroolefin refrigerant compositions with goals of identifying more environmentally sustainable refrigerants for use in stationary AC and refrigeration work, and evaluation of fluids for high temperature energy recovery applications. Dr. Leck received his PhD from the University of Illinois for research to elucidate mechanisms and quantify reaction rates of ozone depletion by chlorine and hydroxyl free radicals in the stratosphere, related to leakage of CFC and HCFC refrigerants.
