Each year, hydrofluorocarbon
sources emit the carbon-dioxide equivalent that is released by 300 coal-fired power plants.
They must reach a goal that includes a cut of methane emissions by 40 percent, hydrofluorocarbon
gases by 40 percent and anthropogenic black carbon by 50 percent below 2013 levels by 2020.
Conventional supermarket refrigeration systems use hydrofluorocarbon
(HFC) refrigerants such as R-404A or R-407A, which have high global warming potentials (GWPs), about 2,100 and 3,900, respectively.
Greenhouse gases are carbon dioxide, methane, nitrous oxide, hydrofluorocarbon
, perfluorocompounds, and sulfur hexafluoride.
These gases are also related to HFC- 134a, a hydrofluorocarbon
and one of the greenhouses gases slated to be banned across Europe from January 2011.
However, many of these first-generation systems rely on hydrofluorocarbon
(HFC) refrigerants, which are thousands of times more potent as global warming gases than carbon dioxide when emitted into the atmosphere.
Coke's Chief Executive Muhtar Kent said that the company, which sells everything from soda and juice drinks to water, will replace hydrofluorocarbon
, also known as HFC, in its new vending machines and coolers by 2015.
CO2 fridges are far less harmful to the environment than the hydrofluorocarbon
units in general use.
Summary: DuPont announced significant progress toward the development and commercialization of a new refrigerant for automotive air conditioning that offers a considerably lower global warming potential than hydrofluorocarbon
(HFC) R-134a, which is used today.
The companies based in China will manufacture and distribute hydrofluorocarbon
125 and other fluid blends, which can be used as coolants in air conditioners without depleting the ozone layer.
Also, while a traditional hydrofluorocarbon
air conditioner requires a heater core to transform engine heat into warm cabin air, Denso's A/C unit can quickly raise cabin temperature through the heat exchange between the [CO.
Convert to a hydrofluorocarbon
(HFC), such as R-134a or HP 62.
