HFC R32 Products
LG R32 A2L [ Mildly FLAMMABLE] refrigerant range of Splits, Multi & Commercial AC Equipment (Up to 12 kW)
R32 can only be used in small applications (max 12 kW or less than 3 kg SYSTEM [Outdoor, Indoor & Pipe work] charge,(see F-Gas equipment sale ban - NOT use) were mostly low-level installation skills required (small one or two-off splits in shops, restaurants, clinics, residential (homes and apartments, etc) [SEE F-GAS BANS] [See LG RECOMENDATIONS]
Space Air says: Air Conditioning that uses a refrigeration cycle or Refrigeration equipment (including domestic refrigerators) used in domestic or commercial applications do not leak (ONLY accidents, bad installation and servicing and rare equipment malfunctions).and, therefore, we are users of refrigerant, not consumers. The risks of a leak with flammable refrigerants will cause Health and safety issues (Fire or death) which defeats the Environmental reasons (low GWP) arguments!.
Hence more emphasise required from Manufacturers, legislators, and industry bodies to ensure safety is not compromised by commercial gains on the back of Environmental claim!. We need more stability and long term sustainability, not commercial consumer jargon.
R410A is considered HIGH GLOBAL WARMING POTENTIAL GWP 2088 IF LEAKED ... BUT Non-FLAMMABLE
R32 is considered LOW GLOBAL WARMING POTENTIAL GWP 675 IF LEAKED ... BUT FLAMMABLE It requires special risk assessment as it is considered by HSE as highly flammable. [See FETA assesment]. See FACTS

Important: F-Gas Regulations CANNOT cover any competence on SAFETY as it is primarily an Environmental qualification ensuring environmentally safe handling, NOT PERSONAL SAFETY.
This course covers all Hydrocarbon refrigerants, including handling of A3 hydrocarbons including R1270 Propylene, R290 Propane and R600a Isobutane. It is also suitable for engineers working with flammable HFO’s and HFC’s including R1234yf, R1234ze and R32
Protocols & Progress
Kigali Amendments UK Progress F-Gas AC Equipment Ban
- R32 is an HFC refrigerant Class A2L (A2L not Used in Large (greater than 3 kg system charge) Splits, Multi splits, VRF or Chiller systems ). It is not a long-term refrigerant, cannot be dropped in, requires Specific Risk Assesment unders DSEAR, require extra training (installer safety) to handle flammables e.g. City & Guilds 6187-21 and require specific guidelines (see LG installation recommendations).
- R410A or R134a or R407C are HFC refrigerants (common Air Conditioning refrigerants which are A1classified (non Flammable), used in Splits, Multi, Commercial, VRF, Chillers, Roof Tops ) - (See F-Gas 2014 Regulations Specifically point 3 (new HFC ban)
the final solution? :
There two regulations that affect the reduction of current HFC refrigerants with high GWP.
The European F-Gas and the Kigali Amendments to Montreal Protocole.
None of them is legally binding and there is no phase-out, and both rely on the future innovation of new Lo GWP refrigerants and equipment manufacturers ensuring no waste and better control on leakage (40 % of refrigerants used in AC/ Refrigeration is used in servicing). see links to both.
