The group of gases detailed above are naturally produced, but their increasing atmospheric concentration is man-made. In contrast, the three industrial fluorinated gases –hydrofluorocarbons (HFC),perfluorocarbons (PFC)andsulphur hexafluoride (SF6)– are solely man-made during industrial processes and...
Crucial debates in the EU's review of F-gases focus on the "phase-out" versus "phase-down" approaches to HFC's, and also on timeframes for implementation. Which pathways can benefit climate and sustain European industry? What would be the optimal result of the EU's review in terms of...
Since no upgrade is required, MULTICOOL refrigerants are the perfect solution for any system that previously used gases such as CFC R12, HFC R134a, HCFC R22, R502, R11 and others. Because of this compatibility, it is easy for companies to move away from the harmful and destructive products...
HFCemissionmitigationThe use of CFCs and HCFCs in foams has been driven by a combination of properties. In some areas the key driver has been their low thermal conductivity as cell gases, whereas, in others, the low toxicity, flammability and boiling point convenience have been the major ...
Her are the greenhouse gases whose emissions should be limited: – Carbon dioxide – CO2 – Methane (CH4) – Nitrogen oxide (N2O) – Hydrofluorocarbon (HFC) – Perfluorocarbons (PFC) – Sulfur hexafluoride (SF6). Scientists refer to these gases as “CO2 equivalents” for their ability to ...
aTemperature-controlled warehouses (and vehicles) present a particular decarbonisation challenge as the refrigerant gases theyuse can have a global warming potential thousands of times higher than that of CO2. HFC123, forexample, has a global warming effect 11,700 times greater 温度控制的仓库(和...
Climate-friendly HFC Alternatives To reduce emissions of HFCs, a variety of climate-friendly, safe and proven alternatives are available. These include natural refrigerants and blends, CO2 and hydrocarbon. As with any change, operators will need to plan accordingly—but this change has been all but...
Researchers at Massachusetts General Hospital for Children (MGHfC) have invented a new term that describes dangers associated with cigarette smoke: third-hand smoke. Study results published in January, 2009 discuss how third-hand smoke is especially dang

(HFC) alternative. It belongs to a family of chemicals called halocarbons, a group which includes HFCs and fluoroketones. Novec 1230 fluid is a fluoroketone, while chemical clean agents like FM-200™ and ECARO-25® are HFCs (HFC-227ea, HFC-125). Novec 1230 fluid has a global ...
