What is the difference between ODP and GWP?
The difference between an ODP and GWP is: Not every refrigerant has an ODP, The ODP is a number given to a refrigerant that says how strong a refrigerant causes ozone depletion in the stratosphere, whereas all refrigerant have a GWP, CFC HCFC and HFC as well as CO2 water vapor and may other chemicals absorb reflect and …
Is CFC banned in India?
India has successfully achieved the complete phase out of Hydrochlorofluorocarbon (HCFC)-141 b, which is a chemical used by foam manufacturing enterprises and one of the most potent ozone depleting chemical after Chlorofluorocarbons (CFCs) .
Where is the ozone layer strongest?
Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.
Where is the ozone hole the worst?
Most of the ozone that is destroyed is in the lower stratosphere, in contrast to the much smaller ozone depletion through homogeneous gas-phase reactions, which occurs primarily in the upper stratosphere.
Is r22 ban in India?
This is because production of chlorofluorocarbon (cfc) based products has been banned in India from January 1, 2003. Earlier, ac manufacturers were using cfc as a refrigerant gas. Though r22 is also an ozone-depleting gas, it is considered less damaging than cfc.
Which AC gas is best?
The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming….
| Refrigerant | Global Warming Potential | Ozone Depletion Potential |
|---|---|---|
| R-134A | 1430 | Zero |
| R-290 | 3 | Zero |
| R-600A | 3 | Zero |
