Hello EMTF Colleagues! Introducing from Trane Technologies, Director of Next Generation Refrigerants Research Steve Kujak.

Refrigerant Transition Update – Impact of Refrigerant Choice on the Design Sustainability
- The orderly transition from CFCs to HCFCs and HFCs achieved a balance between the societal environmental demands for reduced ozone depletion while continuing to improve the standard of living in developing countries while balancing the need for safe (nonflammable) and efficient HFC (hydrofluorocarbon) refrigerants. The next refrigerant transition underway is driven by additional societal environmental demands to reduce the global warming impacts of HFCs. The challenge continues to find refrigerants that are Safe, Efficient that balance Environmental and Equity for consumers (SEEE). Today designers are being asked to consider new lower direct GWP unsaturated (olefins) hydrofluorocarbons (HFOs) refrigerants, some of which have lower flammability (2L’s) under certain conditions. After viewing the presentation, attendees will be able understand the following;

• Drivers behind the new regulations and legislation for HVAC refrigerants
• Actions being taken regionally via the Canada and Cross Border Stakeholders (U.S. EPA, Climate Alliance States, CA, NYS)
• Understand A2L Flammability
• Discuss the HVAC refrigerants choices
• Describe the safety requirements for A2L refrigerants in CSA B52

Steve Kujak - is the director of Next Generation Refrigerants Research for Trane Technologies Over the past 33 years, he has been involved in technology development of new refrigerants, lubricants and HVACR system designs. Steve has been an author or co-author on 60+ publications related to refrigerants and has 40+ patents related to HVAC products.

Steve is a distinguish and exceptional service member of ASHRAE and is involved with global refrigerant safety and use standards used by the HVACR industry.

• Member of the United Nations Environment Program (UNEP) - RTOC (Refrigeration, Air-Conditioning and Heat Pumps Technical Options Committee)
• In coming Director at Large for ASHRAE Board
• Past chair of ASHRAE Standard 34 Designation & Safety Classification of Refrigerants
• Past chair of the Refrigeration Committee Technology Committee for Comfort, Process, and the Cold Chain (REF-CPCC).
