EXPERTISE FROM THE START, FULL SUPPORT TO THE FINISH
UL has been involved in the HVAC/R industry since its inception. Similarly, we have been involved in the implementation of flammable refrigerants in the United States market since day one. Our deep technical expertise and involvement throughout the industry with organizations such as the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) allows us to keep pace with industry needs and global demands.
Though the global market has been using flammable refrigerants for over a decade, the U.S. is now entering the space, further bolstering demand. Concurrently, the larger industry is raising the maximum refrigerant charge while also evaluating new products (A2L refrigerants). In an effort to better understand the impacts of this implementation, UL recently completed a joint study with AHRI investigating the use of these new chemicals. To capture all current market changes, ease global market access and simplify testing, UL is also transitioning our traditional standards, including UL-1995 and UL-484, to harmonized IEC standards.
Flammable refrigerants offer promise to the U.S. market, but demands to keep charge limits low while meeting both EPA and DOE requirements challenge manufacturers. As an industry expert and EPA-recognized certification body for the ENERGY STAR® program, UL is well equipped to help you overcome complex design challenges associated with these new chemicals. UL’s technical experts are thought leaders in this space and can offer assistance from the earliest phases of product design to installation and market guidance. For added flexibility to meet your needs in this evolving space, our services are designed to be modular, allowing you to benefit from UL’s expertise when you need it most.
