Licensed, certified technicians only work with refrigerant gas. CFCs, or Chlorofluorocarbons, are the original refrigerant. They consist of Carbon, Chlorine, and Fluorine. When you hear someone say ‘Refrigerant,’ they are referring to CFCs. HCFCs, or Hydrochloroflourocarbons, are the close neighbor of CFCs.

MEDICAL GAS STORAGE & SYSTEM SOURCE A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and ozone (O 3).Without greenhouse gases, the average temperature of Earth's surface would be about Air monitoring study points finger at a major culprit in a 'global environmental crime' as provinces in northeastern China are identified as a source of an ozone-depleting CFC gas in contravention CFC meaning: 1.

Compressed gas: Colorless, strong pungent odor: Corrosive, non-flammable: III [Threshold Limit Values ppm: 25; Permissible Exposure Limit ppm: 50; Lethal Concentration ppm: 7338; Immediately Dangerous to Life or Health ppm: 500] Argon: Ar: 7440–37–1: Compressed gas: Compressed gas: Colorless, odorless: Simple asphyxiant: IV — Arsine: AsH3: 7784–42–1: Compressed gas A CFC (chlorofluorocarbon) refrigerant is a colorless, odorless gas that contains chlorine, fluorine and carbon. In use since the late 1920s, scientists discovered that CFCs were damaging the ozone layer of Earth's atmosphere, and their usage as propellants in aerosol sprays and coolants in refrigerators began to be phased out in the 1980s.

2019-02-07 2021-01-20 New data has revealed that an estimated half of all CFC gases from UK waste fridges could still be going into the atmosphere. The estimate has come from fridge recovery quality assurance association RAL after it was given figures by the Department for Environment, Food and Rural Affairs. 2020-09-14 Look at other dictionaries: gases — also See CFC gases exhaust gases greenhouse gases residual exhaust gases … Dictionary of automotive terms. CFC — (chlorofluorocarbon) type of greenhouse gas, one of the gases thought to be responsible for the hole in the ozone layer (Ecology) … English contemporary dictionary. CFC CFC Replacements The success of ozone protection has been possible because science and industry have been able to develop and commercialize alternatives to ozone-depleting chemicals. Substitutes for CFCs in electronics: carbon dioxide; Substitutes for CFCs foam-blowing: water, gases for CFC-12. - In 1993-1996, HFC-134a used as a replacement gas for CFC-12 in cars.
