What is the GWP of Freon 12?
about 8500
CFC-12 has a GWP100 Years of about 8500 [8, 21], so R-134a is probably a good trade in terms of environmental impact.
What is the GWP of refrigerant?
Global Warming Potential
The Global Warming Potential (GWP) of a refrigerant is its global warming impact relative to the impact of the same quantity of carbon dioxide over a 100 year period.
What is the global warming potential value of CFC?
2.15. CFC-12 has a GWP of 8500, while CFC-11 has a GWP of 5000. Various HCFCs and HFCs have GWPs ranging from 93 to 12,100.
What is the GWP for R134a?
1300
The aim of this paper is to present the main operating and performance differences between R513A (GWP of 573) and R134a (GWP of 1300), the most used refrigerants for medium evaporation temperature refrigeration systems and mobile air conditioners.
Which is the correct formula of Freon-12?
CCl2F2
Dichlorodifluoromethane/Formula
What is GWP value?
Global Warming Potential, or GWP, is a measure of how destructive a climate pollutant is. The GWP of a gas refers to the total contribution to global warming resulting from the emission of one unit of that gas relative to one unit of the reference gas, CO2, which is assigned a value of 1.
Which is very ideal refrigerant?
Refrigerants
| Refrigerant | Type | Atmospheric lifetime (years) |
|---|---|---|
| R134a | HFC | 14 |
| R407C | HFC blend | 36 |
| R410A | HFC blend | 36 |
| Ammonia (R717) | Natural compound | < 1 |
What is ODP and GWP?
Ozone Depletion Potential (ODP) of a chemical compound is the relative amount of degradation it can cause to the ozone layer. Global Warming Potential (GWP) is a measure of how much a given mass of a gas contributes to global warming.
What is the global warming potential of NOX?
The catalytic role of NOX in the production of tropospheric ozone provides the most prominent contribution. The global waming potential is estimated as GWP (NOX = 30 – 33 and 7 – 10 for the respective time horizons of 20 and 100 years, and is thereby comparable to that of methane.
Which gas has higher global warming potential?
Table 1: High Global Warming Potential Gases
| Global Warming Potentials of Greenhouse Gases | ||
|---|---|---|
| Greenhouse Gas | GWP After 20 Years | GWP After 100 Years |
| Carbon Dioxide | 1 | 1 |
| Methane | 72 | 25 |
| Nitrous Oxide | 289 | 298 |
