A2L class 🔥 R32 Refrigerant (1)
Why flammable refrigerants? Facts needs answers?
Refrigerants (CFC, HCFC, HFC, HC & HFO’s, natural or man-made) are controlled substances due to high pressures 100 - 400 psi, and extreme temperatures -50°C to 140°C, flammability & toxicity as classified by ISO817 & ASHRAE34. They must only be handled by qualified & certified engineers to C&G 2079-11 for (A1 class non-flammable), plus C&G 6187-21 for (A2/A2L/A3 class flammable/explosive).

Who Introduced A2L Flammable R32 as a single component and WHY?
Did you know :
HFC32 (R32) (as a single component) IS THE ONLY A2L class 🔥 FLAMMABLE refrigerant in the HFC family in refrigeration (DX) systems used in Public & Domestic buildings since 1928.
Who Introduced - In 2015 Daikin Industries / DENV Europe re-introduced a range of AC & Heat Pumps equipment (small splits - previously/and still in use, A1 class non-flammable refrigerants since 1928) containing patented 🔥 HFC R32 an A2L class flammable.
By 2017/2018 Daikin and other licensed manufacturers (the Cartel) (such as Mitsubishi (both), Panasonic, LG, Samsung, Toshiba, etc) (withdrew small splits (charged with less than 3kg refrigerant) equipment that used A1 class non-flammable refrigerant R410A, a well established safe refrigerant for over 25 years, earlier than F-gas ban on >750 GWP)
Note: Daikin also controlled the EU quota (by having 28 out of 200+ licenses). (this is under revision due to abuse).
Why Introduced - Daikin introduced A2L class 🔥HFC (R32) as a single component?
Is it commercial suicide, or ignorance of the fact that non-flammables A1 class (CFC, HCFC, HFC Eexcept R32) have been around since 1928? They:
a) Falsely argue that it is environmentally better as it has Low GWP<750 if leaked!, BUT, intentionally avoid to mention of being flammable🔥,(see UL reports)., and can also be explosive💥 (Diesel effect)
b) Falsely claim: According to Daikin Chemicals page 12
"under Japan‘s High Pressure Gas Safety Act, HFC32 (R32) is not classified as a flammable gas?"
BUT It does not state it is non-flammable? (see ISO 817, ASHRAE 34, UL test reports of 1998, 2017 & 2021 & F-gas exemptions)
c) Daikin corporate news regarding R32 pledges, do not mention that HFC-32 (R32) is an A2L class, nor it is flammable?
d) A2L class flammable🔥 R32 as a single component, is falsely claimed (Greenwashing2) that it can carry more energy (aprox 1-4% depending on temperatures) per weight, than A1 class R410A? while Ignoring overall system performance (TEWi) which includes extra safety measures.

B) Refrigerants Engineer's Qualification
Refrigerants are controlled substances due to high pressures (up to 35 bar/500 psi) and extreme temperatures (-50 to 145°C) and must only be handled by qualified & certified engineers to C&G 2079 (A1 class non-flammable) & C&G 6187-21 (A2/A2L/A3 class flammable/explosive) (about C&G)
- F-Gas certification is no longer applicable since June 2021 and was ONLY applicable to A1 class non-flammable. Engineers certification are Environmental & Safety qualification for engineers who handles, install, maintain and service air conditioning, Heat Pumps and refrigeration equipment contain refrigerants. a controlled substance
"C) A2L Extra Installation Safety Materials & Recommendations
Manufactures guides for installation engineers?
Ventilation, Alarms, Pipe protection, equipment Location, Electrical installation, Service recommendations & Engineers extra certification (C&G 6817-21)
Important: The following manufacturers recommendations are not mentioned at point of sale or adverts or websites contravening ASA (Advertising Standards Authority) CAP code.
D) Extra End Users awareness when buying A2L 🔥 flammable R32 (are they?)
End Users MUST clearly be Informed of EXTRA precautionery restrictions & risks (e.g. not have an open fire, etc?),
A2L 🔥R32 is odourless , you cannot identify a leak, while,
1) Manufacturers do not mentioned at point of sale, adverts or web if A2L flammable or A3 explosive.
2) Manuals mixes A2L class 🔥 flammable R32 & A1 class non-flammable R410A without clear labelling on the indoor units for users to identify and to follow? (see how it is done in Hong Kong, Singapore & Australia)
(Notice the contents is similar with all manufacturers in the R32 Cartel? . A clear violation of competition, safety & ethical laws from so called professional manufacturers!)
E) Is equipment charged with A2L class 🔥 R32 LEGALLY Sold?
The answer is NO as it is deceptivley and ambiguously marketed as:
a) It does not meet H&S 2016 no.1107
b) It does not meet Advertising Standards Authority ASA / CAP code
c) It does not meet DSEAR, ATEX, or CE (UKCA) 3rd party certification.
d) Require extra safety precaution and 2 levels risk assesments per application. (Refrigerant Facts)
e) R32 Cartel (controlled by Daikin HFC32 patent) manufacturers do not display warnings on marketing & web materials and force the UK Supply Chain by stopping supply of legall A1 class.
f) It does not meet CCPI Code 11 clauses.
