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。

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.

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 ...

（1）R134a的全球变暖潜能值 (GWP)为1300属于温室气体。 （2）R134a的消耗臭氧潜能值 (ODP)为0，这是R134a成为环保型制冷剂的理由。 （3）R134a的比容是R22的1.47倍，且蒸发潜热小，因此R134a机组的冷冻能力仅为R22机组的60%。 按单位制冷量价格计算，R22机组的价格约为R134a机组的60%左右。 （4）R134a的热传导率比R22下降10%，因此R134a机组的换热器的换热面积需要更大。 （5）R134a的吸水性很强，是R22的20倍，因此对机组系统中干燥器 …

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.

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）。

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.

Global Warming Potential (GWP) is a measure of how much a given mass of a gas contributes to global warming. GWP is a relative scale which compares the amount of heat trapped by greenhouse gas to the amount of heat trapped in the same mass of Carbon Dioxide. The GWP of Carbon Dioxide is by definition 1. Be aware that GWPs are highly controversial.

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.

2024年3月13日 · 全球变暖潜能（GWP）是评估物质对地球温室效应影响程度的指标。 它是相对于二氧化碳的一种比较值，表示在一定时间内（通常为100年）该物质对全球变暖的影响。
