If you want to know what GWP a refrigerant has, you have to check the refrigerant GWP chart. We have prepared a list of 61 refrigerants and their corresponding GWP values , all summarized in a neat chart you can find further on.

Common refrigerants and their Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are indicated below. Global Warming Potential (GWP) is a measure of how much a given mass of a gas contributes to global warming.

R-12 has the highest ozone depletion potential among chlorocarbons due to the presence of 2 chlorine atoms in the molecule. R-12 also has intense global warming potential (GWP) with the 20yr, 100yr and 500yr GWP being 11400, 11200 and 5100 times greater than CO2. [9]

Table 1 shows the environmental impacts of refrigerants R12 and R22 through the Global Warming Potential (GWP) and the Ozone Depleting Potential (ODP). These indexes characterize the action...

2024年12月15日 · GWP: R134a has a relatively high GWP, which has led to its increased scrutiny as environmental regulations tighten. Pressure Differences: R134a operates at higher pressures than R12, requiring careful management to avoid system leaks.

In general, all refrigerant types are characterised by two numbers: Ozone Depletion Potential (ODP) and Global Warming Potential (GWP).

2018年5月28日 · The refrigerating effect per pound for R12 is comparatively low as compared to other refrigerants. A Halide torch is used for leak detection. R12 was completely phased out due to its ozone depleting potential (ODP) = 1 and Global Warming Potential (GWP) = 10000. – r22 refrigerant properties

Specific volume (v), specific internal energy (u), enthalpy (h), and entropy (s) of saturated and superheated Dichlorodifluoromethane (CF 2 Cl 2) - also known as refrigerant 12 R-12. For full table with Entropy and Superheated properties - rotate the screen!

2025年1月18日 · R134a has long been a popular substitute for R12 due to its zero ozone depletion potential (ODP) and convenience. Although it has a higher global warming potential (GWP), its efficiency makes it suitable for many applications, particularly in automotive air conditioning systems.
