Fluorinated gases, or F-gases, are a range of greenhouse gases widely used in refrigeration and air-conditioning, most notably hydrofluorocarbons (HFCs).

In April of this year, EPA finalized a rule that made changes to the SNAP list to include, for the first time, hydrocarbon refrigerants for limited equipment and sized charges. The four compounds are HFC-32, ethane, isobutene, propane, and R-441A. The phase-out schedule for HCFC and the phase-down schedules for HFC can be seen in the tables below. It is worth noting that the non-A5 countries rely on baselines that are frozen already while the A5 countries have a combination of the HCFC quota (already frozen) and a HFC … A ban came into operation in Northern Ireland on 1st January 2020 that prohibited certain types of fluorinated greenhouse gases ("F-gases") with a global warming potential ("GWP") greater than 2500 being used to service or refill refrigeration systems in NI. the Australian HVAC&R market has enjoyed a period of HFC use without legislative restriction. This is due to change at the end of 2017 with the introduction of HFC import quotas, which are the Australian government’s chosen mechanism for meeting its international obligation to phase down the use of HFC gases under the amended Montreal Protocol. The chemical industry’s own data on F-gas emissions shows 59% of all HFC 134a ever produced is already in the atmosphere, so this number could be much higher.

5 to 49.999 tonnes. At least every 12 months. If a fixed leak detection system is installed, the leak check frequency is halved, so a 3 monthly frequency becomes 6 monthly. A chiller with 25 kg R410A (2088) will require 6 monthly leak checks, whereas a chiller with 25 kg R134a (1430) needs 12 monthly leak checks. In addition, legislation is increasingly targeting refrigerant gases with high GWP. BOC offers a number of lower GWP HFC solutions, such as the use of R407A or R442A instead of R404A.

HFC gas was originally proposed as a viable replacement for CFCs, chemical compounds which scientists realized were having a profound impact on the ozone layer. In 1928 Thomas Midgley Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12). The name is a trademark name owned by DuPont (now Chemours) for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant.

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.

The future drastic phase-down of F-Gases, e.g. as part of the EU F-Gas Regulation, already leads to a demand for R404A/ R507A substitutes with GWP values clearly below 500. Although this is possible with an adequate composition of the blend (high proportions of HFO, R152a, possibly also hydrocarbons), the disadvantage will be its flammability (safety groups A2L or A2).

GWP values for ozone depleting substances can range, for example, from 2 up to about 14,000. The GWPs of commonly used HFCs can range from <1 to about 12,500. Global warming potential (GWP) is a measure of the relative global warming effects of different gases. It 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.
