As 2014 winds down, the end of new and imported hydrochlorofluorocarbons (HCFCs) is in sight and limitations on certain hydrofluorocarbons (HFCs) seem more and more likely.
So to continue to meet refrigeration needs, f-gas proponents are turning to low-global warming potential (GWP) HFCs and hydrofluoroolefins (HFOs) while advocates of so-called natural solutions — hydrocarbons (HCs), CO2, and ammonia — continue to build their cases.
