Fluorinated gases have a potent greenhouse effect and are widely used as refrigerants at end of life, both after the adoption of alternatives to HFC refrigerants.

The HFC phase-down – What are the solutions and how should the industry plan ahead? Graeme Dewerson BSC, Affil.AIRAH, Commercial Manager – A-GAS Australia Pty Ltd ABSTRACT The introduction of an HFC import quota as the mechanism for the HFC phase-down will impact the availability of high-GWP refrigerants over time.

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. GWP of refrigerant R404A: 3922. This means that every kg of R404A released into the atmosphere has the same greenhouse effect as 3922 kg CO 2. HFC Phase-down For example, the release of one tonne of HFC 23 is equivalent to releasing 14,800 tonnes of carbon dioxide into the atmosphere.

CARB maintains a list of GWPs for some common refrigerants. For more information, please visit the IPCC website . 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.

Leak Checking Requirements The new F-Gas regulation sets leak checking requirements based upon 5, 50 and 500 CO2 Equivalent Tonnes.

Hydrofluorocarbons (HFCs) such as R-134a, R-143a, R-407c, R-404a and R-410a (a 50/50 blend of R-125 / R-32) were promoted as replacements for CFCs and HCFCs in the 1990s and 2000s.

Multiple gases contribute to the greenhouse effect that sets Earth’s temperature over geologic time. Small changes in the atmospheric concentration of these gases can lead to changes in temperature that make the difference between ice ages when mastodons roamed the Earth, and the sweltering heat in which the dinosaurs lived. Among the HFCs and HFC-blend refrigerants affected by the regulations are several that are familiar to facility managers: R-404A, R-134a, and R-410A and R-407C, used to replace R-22. Under the rules, new chillers would no longer be produced using these refrigerants after Jan. 1, 2024. HFC Gas Fill Valve for HG-199 M9 Green Gas Magazine SKU: HG-199-001. $6.95 Qty Add to Cart.

HFCs (hydrofluorocarbons) are the third generation of fluorine-based gases. These products are categorised as having zero ODP (Ozone Depleting Potential) and medium to high GWP (Global Warming Potential) and so offer a more environmentally friendly alternative to CFCs and HCFCs.HFCs are used in a wide range of refrigeration and air conditioning equipment specifically designed for them, and as

A small proportion of large refrigerators and freezers, particularly imported models, still use HFC 134a. Under the 2014 F-Gas Regulation the use of any HFC with a GWP above 150 will be banned in this market from January 2015.
