Research & Development Roadmap: Next-Generation Low Global Warming Potential Refrigerants
You are here
Refrigerants are used in a wide variety of heating, ventilation, air conditioning, and refrigeration (HVAC&R) equipment. The current generation of refrigerants, hydrofluorocarbons (HFCs), have significant global warming potential (GWP) when released to the atmosphere. This research and development (R&D) roadmap for next-generation low-GWP refrigerants provides recommendations to the Building Technologies Office (BTO) on R&D activities that will help accelerate the transition to low-GWP refrigerants across the entire HVAC&R industry. Each recommendation is built on direct input from industry stakeholders on the key challenges that must be addressed to achieve widespread implementation of next-generation refrigerants. This roadmap reflects the current state of the industry in 2014 and builds upon a similar roadmap published by BTO in 2011.
