Overview

A disruptive change is currently underway in the heating, ventilation, air conditioning and refrigeration (HVAC-R) refrigerant market. Driven by environmental concerns, global promoters are advocating the phase-out of traditional refrigerants in favor of new alternatives with a lower global warming potential (GWP).

New regulatory guidelines mean that businesses face different requirements depending on where and how they operate.  A large number of new refrigerants have emerged, along with new technology to support them.

UL recently completed a landmark joint study with the Air-Conditioning, Heating and Refrigeration Institute (AHRI) investigating the use of these environmentally friendly refrigerants. 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 International Electrotechnical Commission (IEC) standards.
