2024年12月27日 · The Technology Transitions Rule specified global warming potential (GWP) values of common substitutes for purposes of implementing this rule. These values are listed in 40 CFR 84.64 and are provided here as reference.

2023年9月15日 · Using the latest updated data from UNEP’s RTOC 2022 report, we have compiled the 100-year GWP and 20-year GWP values of hydrofluorocarbon-based (HFC) refrigerants. Our table includes single component HFCs as well as blends that include at least one HFC in their composition.

空調工程師學會(簡稱ASHRAE,American Society of Heating, Refrigerating, and Air-Condition. Engineers )公告其認可冷媒編號之HFCs 種類,包括純物質與混合物,以及國內常見之HCFCs 種類等之GWP值,此值目前是依據蒙特婁議定書以政府間氣候變遷專門委員會(簡稱IPCC,Intergovernmental Panel on ...

GWP是温室气体排放所产生的气候影响的指标，表示在一定时间内（20年、100年、500年），某种温室气体的温室效应对应于相同效应的CO 2 的质量，CO 2 的GWP=1.0。

2024年8月16日 · Use of HFC-134a in MVAC systems accounts for an estimated 24% of total global HFC consumption. It is the most abundant HFC in the atmosphere. The restriction of HFC-134a will occur under a broader prohibition of any substances with a Global Warming Potential (GWP) higher than 150 in the MVAC sector.

2024年1月31日 · 美国环保署最终规则（Final rule）于2023年10月5日签署，该规则限制在气雾剂、泡沫以及制冷、空调和热泵产品和设备中使用全球升温潜能值（GWP值）较高的氢氟碳化物（HFC）。

Most common refrigerants like R410A, R22, and R134A have a GWP of about 2,000. That means they are about 2,000 worse greenhouse gas than carbon dioxide. GWP of the most commonly used refrigerants in HVAC like R410A, R134A, and R32 is about 2,000. Methane GWP is within the 27 to 30 GWP range.

1,1,1,2-Tetrafluoroethane (also known as norflurane (INN), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion ...

This page lists hydrofluorocarbon (HFC) and HFC blend refrigerants, and some non-HFC refrigerants. The lists provide: global warming potential (GWP) refrigerant safety classification blend composition (where applicable). For completeness, some HFCs that are not commonly used as refrigerants are listed.
