WebGlobal warming potential values of hydrofluorocarbon refrigerants. Here are lists of HFCs and HFC blends, and their global warming potentials (GWP). For the purposes of the … WebR452B and R454B offer easier drop-in replacement, along with the flexibility of a multi-refrigerant system. R454B also has a lower GWP, which means it might remain in use for longer as standards advance. Refrigerant choice for each application should be made on a case-by-case basis. When replacing R410A, here's what you need to know:

WebHCFC refrigerants R-124 and R-142b were less stable but still superior to the incumbent R-12. R-123 was found to be the least stable refrigerant investigated in Huttenlocher’s … WebGWPs are calculated using a set time horizon. All GWPs used for GHG inventory purposes are considered over a 100-yr timeframe. GWPs are updated periodically with improvements to the underlying science. 100-yr GWPs from the IPCC second assessment report (SAR) and fourth assessment report (AR4) AR4 GWPs are used for the 2000-2024 emission … read box plots

XP10 was commercialized as a part of a broad portfolio of Opteon™ refrigerants, which represent a breakthrough line of low-GWP solutions. They were developed to help meet proposed … WebHCFC refrigerants R-124 and R-142b were less stable but still superior to the incumbent R-12. R-123 was found to be the least stable refrigerant investigated in Huttenlocher’s study; however, it was determined to be at least 10 times more stable than R-11, the refrigerant it was intended to replace in low-pressure chiller applications. how to stop mirroring on iphone camera
