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.

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 …

在碳盤查的實務中，不同類型的冷媒是否需要計入溫室氣體排放量，取決於其全球暖化潛勢（gwp）數據以及所屬的管控範圍。 本篇將聚焦於 R-600a 與 R-22 冷媒，並解析其在 ISO 14064 碳盤查中的處理方式。

The most common refrigerant today, R-22, has a 100-year GWP of 1,810, almost 2,000 times the potency of carbon dioxide, so just one pound of R-22 is nearly as potent as a ton of carbon dioxide.

As an additional environmental concern, R-22 is a powerful greenhouse gas with a GWP equal to 1810 (which indicates 1810 times as powerful as carbon dioxide). Hydrofluorocarbons (HFCs) are often substituted for R-22 because of their lower ozone depletion potential, but these refrigerants often have a higher GWP.

Common refrigerants and their Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are indicated below. Global Warming Potential (GWP) is a measure of how much a given mass of a gas contributes to global warming.

2) GWP - The GWP, or Global Warming Potential. A measurement (usually measured over a 100-year period) of how much effect a refrigerant will have on Global Warming in relation to Carbon Dioxide. CO 2 has a GWP of 1. The lower the value of GWP - …

May 15, 2019 · 目前在家用空调和热泵中广泛应用的制冷剂是r22，它属于臭氧消耗物质hcfc，根据蒙特利尔议定书，我国到2030年将淘汰所有制造业hcfc的生产与消费[1]。 R22的替代制冷剂大体可分为三类：

R32的ODP=0，GWP=675，属于绿色环保制冷剂，是R22的一个重要替代品，目前在欧美、日本等国家的家用空调中已有大量应用。 R290的化学成分为丙烷（CH 3 CH 2 CH 3），毒性很小，有可燃性，安全等级为A3。 R290的爆炸极限为2.1% ~ 10.0% [3]，爆炸点比R32要低得多。 R290的ODP=0，GWP=20对全球变暖的促进作用非常小，它属于天然有机物，可以从石油液化气直接获取，价格低。 R290热力性能好，气化潜热大，系统充液量少，相同工况下排气温度可比R22 …

Aug 9, 2023 · 由大金研发，主要用于替代空调和热泵领域的r22和r410a制冷剂，r32较r22可以提升约10% 能效，较 r410a的gwp值，r32是其1/3。 在此之前，制冷剂在可燃性方面非黑即白，即不可燃和易燃易爆，R32在此之前属于易燃易爆，通过修订标准，A2L即弱可燃制冷剂诞生，R32位列 ...
