When I first started writing about the HVACR industry more than 25 years ago, the term used to describe the harmful effects of refrigerant emissions in the atmosphere was ODP. After scientists discovered the hole in the ozone layer, they determined that it was caused by the chlorine in chemical compounds like CFCs, which were widely used in aerosols and refrigerants. They needed a measurement to describe the amount of ozone depletion caused by various substances, thus the term ODP was born.

Last December, EPA proposed to modify the use conditions required for use of three flammable refrigerants — isobutane (R-600a), propane (R-290), and R-441A — in new household refrigerators, freezers, and combination refrigerators and freezers under the Significant New Alternatives Policy (SNAP) program to reflect an updated standard from Underwriters Laboratories (UL).

Attendees will hear from experts on refrigerant regulations and policy, as well as those from leading engineering and manufacturing firms that specialize in natural refrigerant technologies. Together, attendees will map refrigerant choices and see what the future holds for each option.

Danfoss will host live webinars that will explain the impact of new regulations and offer support for how to comply with them.
