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.

GWP stands for Global Warming Potential. It is a metric that denotes how harmful greenhouse gas a refrigerant is. Carbon dioxide (CO 2) is the benchmark greenhouse gas with a designated GWP of 1. 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.

High-global warming potential (high-GWP) refrigerants include all ozone-depleting substances and any refrigerant with a GWP of 150 or higher. What is Global Warming Potential? Global Warming Potential, or GWP, is a measure of how destructive a climate pollutant is.

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 Assessment Report, 2020 (AR6).i.

WHAT IS LOW GLOBAL WARMING POTENTIAL (GWP) CLASSIFICATION? – GWP numbers for a refrigerant are calculated and published by the United Nations Intergovernmental Panel on Climate Change (IPCC). The GWP number is based on the refrigerant’s properties, such as lifetime, radiative forcing effect, and current

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。 通常基于100年计算GWP，记作GWP 100，《蒙特利尔议定书》和《京都议定书》都是采用GWP 100。 制冷剂应具有可接受的安全性，安全性主要包括毒性和可燃性，国家标准《制冷剂编号方法和安全性分类》GB/T 7778-2017将制冷剂的毒性分为A类（低慢性毒性）、B类（高慢性毒性），将可燃性分为第1 …

A key property of R-454B refrigerant is its low global warming potential (GWP). Compared to older refrigerants, R-454B has a significantly lower GWP, meaning it has a reduced impact on climate change. This makes it a more sustainable choice for HVAC systems, aligning with the growing focus on environmental responsibility.

Our GWP calculator makes it extremely easy to find out the GWP value (global warming potential) of the refrigerant used in your equipment. All you have to do is enter the name of the refrigerant you use and how much of it you load into your equipment.

• R-290 and R-441A are listed acceptable substitutes (subject to use conditions) in room AC units by the U.S. EPA Significant New Alternatives Policy (SNAP) program • Efficiency and performance expected to be equal to or better than R-410A, particularly in regions with warmer climates • Safety concerns for flammable refrigerants require

2025年2月13日 · r-290等低gwp制冷剂在减少lccp方面显示出巨大前景。 瑞典：通过优化系统设计和减少制冷剂充注量，显着降低了LCCP。 德国：开发了将建筑模拟与热泵负载动态结合的整体概念，提出了在住宅热泵中使用R-290的建议。
