High Global Warming Potential Refrigerant Gases And Climate Change
The global warming potential (GWP) of a chemical would refer to its global warming impacts at a given period of time. Refrigerants have very high GWP which means that these cause larger damage to the atmosphere. To illustrate, carbon dioxide has a GWP pf 1. 0, in comparison to refrigerants having hundreds or even thousands of GWP, which means that such stay longer in the atmosphere, causing greater damage to the ozone layer in a given period of time.
All greenhouse gases are assigned with global warming potential values. Scientists use this number in determining how refrigerant gases will bring impact to global warming in 20, 100,
nike airmax tn, and 500 years. Most greenhouses gases stay in the atmosphere longer than 20 years, with many as high as 100 years. Unless action is taken to control carbon emissions and dangerous refrigerant gases, considerable harm will be done to the Earth.
There are three factors which are considered in the process of determining the global warming potential of substances. They are the amount of absorption of infrared radiation, the atmospheric location of where absorption takes place,

To maintain a healthy environment, the lower the global warming potential of a substance or chemical,

Chemicals with the highest global warming potential are hydrochlorofluorocarbons (HCFCs), such as those found in refrigeration and cooling systems or HVAC-R equipment. Hydrochlorofluorocarbons have GWPs ranging from 120 to 12,

Refrigerant R-114 or dichlorotetrafluoroethane has one of the lowest GWP value at 3, while R-113 or trichlorotrifluoroethane has one of the highest at 4800. 9. The alternative SNAP refrigerants being developed by the EPA and various refrigerant gas manufacturers have no impact on global warming and are being used in the production of all types of new refrigeration and air conditioning systems.
Because refrigerants used in commercial refrigeration and air-conditioning systems, as well as heating, ventilation and air conditioning systems, have a high global warming potential, facilities with this equipment in use are required to follow guidelines set forth by the U. S. International protocols and treaties mandate the reporting of refrigerant gas usage to environmental regulation authorities.
New regulations are helping in the reduction of refrigerant emissions with high global warming potential, though there are still reports of refrigerant leaks from systems which are poorly maintained.
By implementing leak reporting regulations and guidelines for fixing leaks, the U. S. is controlling the problem. The U. S. Clean Air Act is also well underway to phasing out harmful refrigerant gases by 2015 to ensure our environment remains healthy for years to come. Facilities should comply with these regulations in order to avoid penalties and sustain the future of the environment.
