12 Dec 2005 A list of alternatives has been identified in Figure 1. Of the options identified, several HFC refrigerants have emerged as candidates the impact of greenhouse gas emissions, as HFCs reduce total greenhouse gas rel
The HFC phase-down is a gradual reduction in the maximum amount of HFCs permitted to be imported into Australia. Beyond that, the discharge gas temperature of most R404A/R507A alternatives is considerably higher than for these HFC blends. In single stage low temperature systems this may lead to restrictions in the compressor application range or require special measures for additional cooling. Hydrofluorocarbons (HFCs) are a group of industrial chemicals primarily used for cooling and refrigeration. HFCs were developed to replace stratospheric ozone-depleting substances that are currently being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer. Information about the 2015 EU F-gas regulation. Explore the schedule, quota system, and sectorial bans on high-GWP refrigerants, including hydrofluorocarbons.

Foams are a significant source of HFC emissions. These gases are used during the production of foams as blowing agents.
HFC-152a and HFC-134a are increasing in the atmosphere. This growth is Table 4.1b lists additional synthetic greenhouse gases without established
Hydrofluorocarbons (HFCs) are greenhouse gases (GHGs) commonly used by federal agencies in a wide variety of applications, including refrigeration, air-conditioning (AC), building insulation, fire extinguishing systems, and aerosols. HFCs have high global warming potential (GWP), raising concern about their impacts as they become increasingly used GWP is “Global Warming Potential” and all substances have a GWP in the form of a number which is representative of its potential as a greenhouse gas by comparing it to CO 2: Example: GWP of CO 2:1.

As part of the Coalition’s initiative on the promotion of HFC alternative technologies and standards, partners approved funding in August 2012 to develop an initial set of HFC inventories in six medium and large volume consuming developing countries.

Now, HFCs are rapidly building up in the atmosphere. If their use isn't stopped, HFC emissions will increase to 7–19 percent of global greenhouse gas emissions by 2050. In Washington, HFCs account for about 4 percent of overall greenhouse gas emissions.

Therefore, in view of future restrictions (for example EU F-Gas Regulation), the use of this refrigerant will still be possible for quite some time. If required, systems can later be converted relatively easily to non-flammable (A1) HFO/HFC alternatives with a GWP of approx. 600 ( Low GWP" alternatives for HFC refrigerants ).
