1Refrigerant Legislation & Guidelines

Manufacturers do not decide what the 3Supply Chain or Consumers should or should not use including refrigerants & should be:
"clear, accurate, up-to-date, accessable and unambiguous"

 A) UK Gov & International Regs regarding F-Gas

  1. Bans on GWP >750 / Facts about Refrigerants (F Gas - fluorinated gases)

    EU/UK ban on 1st January 2025, the supply (not the use) of split system ONLY with less than 3 kg charge refrigerant having GWP >750 (e.g. R410A) 

    Clearly states that if there is no alternative that is SAFE & Compliant to meet exemptions in the ban:

    • The ban creates technical or SAFETY issues

    • Total greenhouse gas emissions over a specific products life cycle, including energy consumption, will be lower because of the excemption


    Note: The ban regarding Splits (Indoor + Outdoor + refrigeration pipe work) and should include package / Mono (Heat pumps) charged with less than 3 kg of refrigerant with GWP > 750

  2. UK Government Study in 2018,

    Gov Study: The impact of high GWP (above 750) A1 class  non-flammables refrigerants (e.g. R410A) in Heat Pumps, concluded that the carbon benefit of displacing fossil fuels was around 17 times higher than the impact of refrigerant leaks. without the risks, cost and uncertainty of A2L class 🔥 flammable refrigerants future (e.g. R32) 

    "Having low GWP but being A2L class 🔥 flammable (like R32 as a single component) defeats the objective reason of protecting the environment 
    IF leakedwhile creating a fire risk!!"

  3. UK Regulations and Statutory Instruments ASA, CCPI, Safety Bill, H&S: 


  4. Refrigerant handling, classification and regulations

  5. Kigali Amendment 2016    Click for more > >  

    In October 2016 the Kigali Amendment was adopted by all Parties to the Montreal Protocol. The Kigali Amendment brings the future production and consumption of hydrofluorocarbons (HFCs1) under the control of the Protocol and will make a major contribution towards the fight against climate change. Control of HFC production and consumption will add to the climate benefits already achieved by the Montreal Protocol through the phase-out of ozone depleting substances (ODS) including CFCs and HCFCs.

Response to Q&A


3Suuply Chain (AC & Refrigeration Industry): 

The supply chain in the AC & Refrigeration Industry includes any diciplne who handles any flammable materials, such as A2Lclass 🔥 flammable (R32) or A3 class flammable 🔥 / explosive 💥 (R290, R270, R600a) refrigerants, that requires extra risk assesment, extra safety & extra handling certification.

Refrigerant classification
There are over 300 types of refrigerants in THREE Safety Classifications with regards to flammability, in accordance with ISO 817:2014 (E) & ASHRAE34 International Standard clearly indicate that: 
               A1 class non-flammable, A2/A2L flammable🔥 & A3 Highly flammable/Explosive 🔥💥

2 Greenwashing
"Greenwashing is a deceptive form of marketing that claims a company's products, policies and goals are environmentally friendly and therefore do less damage to nature, with an underlying purpose to increase profits"

5Business Cartel ; Daikin Industries/ Chemical have patented (aprox3 00+ patents) A2L flammable 🔥R32 refrigerant and components used in small splits air conditioning equipment and licensed the patents to Japanese manufacturers (such as Mitsubishi Electric/Heavy, Fugitsu, Toshiba, etc), Korean manufacturers (LG & Samsung) & Chinese AC manufacturers, conditional on withdrawing current R410A non-flammable in small splits (refrigerant charge less than 3kg) and not mentioning that R32 is flammable 🔥 in their promotional materials or website?.
This has been applied to UK & and some EU but not the rest of the world. Daikin is an International manufacturer and claim meeting International standards & safety obligations & Code of Ethics: 


6 Public Buildings means any building having free entrance or permissible for entry to the common masses then that building will be called public buildings e.g. Offices, Restaurants, apartments, shops, Hospitals, Hotels, Supermarkets, Sports centres and Care homes.
