   As refrigerant blends are formed simply by mixing two or more single component refrigerants, the GWP of a refrigerant blend is the mass-weighted average of GWPs of individual components in the blend. That is, to calculate the GWP of a blend, one simply adds the GWP of the individual components in proportion to their mass. The GWP of blends are ...

   Jun 27, 2012 · The global warming potential of a blended refrigerant gas can be easily calculated by using the blend composition and the known GWPs for each gas contributing to the blend. An example of this calculation is shown below using R410A, a common refrigerant in air conditioning systems that has replaced the phased-out R22 in residences and businesses in many places, including Europe and the USA.

   the GWP values in the Montreal Protocol text (Annexes A, C and F) to calculate these. The GWP values in Table 2 are for single component refrigerants. In the case of refrigerants which are mixtures (or blends) of more than one refrigerant, the GWP is calculated as a mass-weighted average of the individual components.

   Sep 15, 2023 · The Global warming potential (GWP) is the metric most commonly used to indicate the climate impact potential of a refrigerant emission. [1] According to UNEP, GWP can be defined as a measure of the relative global warming effects of different gases (in this case, refrigerants). It assigns a value to the amount of heat trapped by a certain mass ...

   Decafluoropentane. CF 3 CHFCHFCF 2 CF 3. 1,640. Some refrigerants are not single chemicals but a mixture of two or more chemicals, called blends. HFC blends may contain only HFCs, or HFCs mixed with other chemicals. For example, R‑410A is made up of 50% R‑32 and 50% R‑125.

   What is the GWP value of a refrigerant?

   • The GWP value of a refrigerant defines its global warming potential relative to CO₂ (also known as CO₂ equivalent). The value describes the global warming effect over a certain period of time, which for refrigerants is usually 100 years. The higher the GWP value, the more harmful the corresponding substance is to the climate.

   • Each has a GWP value of less than 5. Here are lists of HFCs and HFC blends, and their global warming potentials (GWP). These GWP values apply under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 (the Act). They are the 100-year GWP's from Intergovernmental Panel on Climate Change (IPCC) fourth assessment report, 2007 (AR4).

   What is a mixture of PFCs and HFCs?

   • However, many combinations of PFCs and HFCs, colloquially known as ‘refrigerant gases’, are actually mixtures of several different gases in set proportions. While the IPCC reports don’t publish GWPs for blends, Defra and DECC present a selection of common refrigerant blends in their “Guidelines to GHG Conversion Factors for Company Reporting”.
