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.

This document provides 100-year time horizon global warming potential (GWP) values from the Intergovernmental Panel on Climate Change (IPCC). The table below is adapted from the IPCC Sixth

Anyone working with refrigerants must independently check the safety classification of any refrigerant. This page lists hydrofluorocarbon (HFC) and HFC blend refrigerants, and some non-HFC refrigerants.

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 Climate Change)之第四次評估報告(簡稱AR4,Fourth As.

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.

Table 1 (overleaf) provides some sample GWP values. Examples of CFC-12, HCFC-22 and HFC-134a have been selected to illustrate the progression in knowledge over time leading to the updating of the GWP values. The examples also indicate some of the different sources of values. WHAT IS GWP? INTRODUCTION

HFC-23 has a global warming potential (GWP) that is 14,800 times higher than carbon dioxide over 100 years. Cooling equipment contributes additional climate emissions through its high energy consumption.

2024年5月25日 · HFCs, depending on their specific composition, can have a GWP several thousand times greater than CO 2, making even small quantities significant contributors to global warming. HFC-134a: Commonly used in automotive air conditioning, HFC-134a has a GWP of 1,430 over a 100-year period.

2021年9月10日 · IPCC AR6 in - Climate Change 2021, The Physical Science Basis- Chapter 7.SM [1] provides updated GWP values for relevant substances. EFCTC has updated its data tables to include the values from the most recent IPCC …
