The typical air-conditioned car carries two to three pounds of chlorofluorocarbons
as a refrigerant, commonly called R12.
Both awards were presented by EPA officials in Baltimore, during the 1991 International Chlorofluorocarbon
(CFC) and Halon Alternatives Conference.
That's thanks to a law in 1987 banning chlorofluorocarbons
(CFCs), or ozone-chewing chemicals, from aerosol cans and refrigerators.
A magnetic-cooling system could also be less polluting than current systems because it wouldn't use environmentally harmful chemicals, such as ammonia or chlorofluorocarbons
The heater uses carbon dioxide as a refrigerant instead of chlorofluorocarbons
, which are commonly used in such devises.
China and Venezuela have pledged to phase out the use and production of chlorofluorocarbons
(CFCs) by the end of 2007, two years earlier than required by the Montreal Protocol on Substances that Deplete the Ozone Layer.
Another SDPI expert Kashif Salik said Chlorofluorocarbons
(CFCs) are greenhouse gases.
As part of its commitment by Montreal Protocol concerning the non-use of substances that cause ozone depletion, in the beginning of this year the ministry limited the use of chlorofluorocarbons
by setting specific rations for the companies that use this substance.
ISLAMABAD, 06 June, 2009 (Balochistan Times) --Ministry of Environment, in collaboration with its partners is holding a Stakeholders Workshop on Hydro Chlorofluorocarbons
(HCFC) on Monday.
These contain gases such as Chlorofluorocarbons
(CFCs) and HCFCs, used for the coolant and insulation.
The most common chemicals include chlorofluorocarbons
(CFCs), halons and chlorine-based solvents that have been used for more than 30 years as refrigerants, cleaning agents, spray propellants, foams and fire extinguishers.
Coolex manufactures patented multistage cooling systems that use no refrigeration or chlorofluorocarbons
More uniquely, when mechanical power is supplied to the heat engine, it could become a cooling device without the use of a compressor and chlorofluorocarbons
The chemicals emitted include trace amounts of ozone-destroying chlorofluorocarbons
, perfluorocarboxylates (which accumulate in animal tissues), and trifluoroacetic acid (which has unknown effects on animals and humans).
Moreover, Mabury says the team was surprised to find ozone-depleting chlorofluorocarbons
(CFCs) and greenhouse gases known as fluorocarbons coming from the heated materials.
