Ammonia in most refrigeration systems is a clear liquid and gas with nearly zero means that it stays in the atmosphere for only a few days, as opposed to HFC,
HFC refrigerants These are substances containing HYDROGEN, FLORINE and CARBON chemicals. The HFC gases are used extensively in every day RAC systems. There is no current ban upon these gases but responsible use and equipment inspections is mandatory under the "F gas" regulations.

© 2003-2012 Princeton University, Farlex Inc. Hydrofluorocarbons or 'HFCs' have been increasingly used in the last decade or so as an alternative to ozone damaging CFCs in refrigeration systems. Unfortunately, though they provide an effective alternative to CFCs, they can also be powerful greenhouse gases with long atmospheric lifetimes. Hydrofluorocarbon (HFC) clean agent is a chemical compound that suppresses Classes A, B and C fires without water or harmful chemical residue. In 1994, HFC clean agents largely replaced chlorofluorocarbon (CFC) halon agents, which cause ozone damage. Hydrofluorocarbons are organic compounds that contain hydrogen (hydro) and fluorine (fluoro), and can damage the environment. In 1928 Thomas Midgley Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12).

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.

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.

Freon can be in a liquid and/or gas form. For each temperature it's at it Freon has a high affinity for mineral oil, meaning that it carries oil with it every where it goes. R134a (HFC-134a) (Suva) (Klea) Suva is DuPont's brand
2021-04-09 · For example the global warming potential of HFC 404A is 3,922. Therefore the tonnes CO 2 equivalent of 10kg of HFC 404a is calculated as follows: Mass (in tonnes) of F gas multiplied by GWP of F gas Derzeit ist HFC-134a das einzige bekannte fluorierte Gas mit einem GWP-Wert über 150, das in mobilen Klimaanlagen verwendet wird. eur-lex.europa.eu The EU Commission is preparing to publish its proposals for these exemptions at HFC definition: HFC is a type of gas used in refrigerators and aerosols.
