Looking Forward Tech Session - The Future of Refrigerants

October 20, 2020
12:00 PM - 2:00 PM


Safe non-flammable low toxicity F-gases allowed for an exponential increase in the standard of living of society through increased food productivity, reduction in heat related deaths, increased worker productivity and migration of people to cities and to hotter climates. Refrigerant safety was successfully maintained during the chlorofluorocarbon (CFC) refrigerant transition starting the 1990’s to lower ozone depleting refrigerants with the development hydrochlorofluorocarbons (HCFC’s) and hydrofluorocarbons (HFC’s) chemistries. 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 and minimize the societal safety impacts for everyone.

New societal environmental demands to control climate change are driving the development of new regulatory policies to restrict and lower the direct GWP (global warming potential) impact of F-gases. These regulatory activities have driven significant refrigerant technology development activities globally as a result of climate change concerns. Today designers are being asked to consider new lower direct GWP unsaturated hydrofluorocarbons (HFOs) refrigerants, some of which are slightly flammable under certain conditions, as well as revisiting the application of natural refrigerants, like carbon dioxide, ammonia, hydrocarbons and water. This presentation will cover a brief history of refrigerants, how much refrigerants contribute to global warming, update the current regulatory situation, how to name and explain the new ASHARE 2L flammable classification and discuss the future challenges with the new refrigerants. Insights will be shared into the impact on safety and other design considerations with the various refrigerants being proposed by application.
