Ammonia has no greenhouse gas or ozone-depleting potential. Ammonia also stays in the atmosphere for only a few days, as opposed to HFC, which stays in the atmosphere for multiple decades. Interestingly enough, ammonia has also been used to reduce pernicious gas stack emissions when injected into boiler and gas exhaust.

Hfc gas meaning

In 1928 Thomas Midgley Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12). The name is a trademark name owned by DuPont (now Chemours) for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant. HFC emissions (excluding HFC-23 by-product) currently account for around 1% of global greenhouse gas emissions and as much as 3% in many developed countries. If left unchecked, these emissions will increase to 7-19% of all greenhouse gas emissions by 2050 and off-set most if not all mitigation actions pledged by countries to date.

Hydrofluorocarbon (HFC), any of several organic compounds composed of hydrogen, fluorine, and carbon. HFCs became widely used as refrigerants in the late 1980s, but their status as potent greenhouse gases led to their manufacture and use becoming increasingly regulated in the 21st century.

HFC-134a: a Potent Greenhouse Gas. Most common refrigerant used in MVAC systems since the 1990s; Potent greenhouse gas with a global warming potential that is 1,430 times that of CO 2; Use of HFC-134a in MVAC systems accounts for an estimated 24% of total global HFC consumption. It is the most abundant HFC in the atmosphere.
