 Why flammable refrigerants? Facts needs answers?

About refrigerants?

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 (Greenwashing2that 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.

  Is A2L class flammable   🔥R32 safe? and is it legal?

Duties, responsibilities and obligations when dealing/handling or specifying A1, A2L or A3 class refrigerants

A)    Manufacturer, Importer, Distributor legal OBLIGATIONS

                                                                                                                                          1Back to menu     
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,
Note: 
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 DSEARATEX, 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.

Reference

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 - fire Supressor (such as R134a, R410A,R12, R22,etc), A2/A2L flammable🔥 (such as R32, R454B) - fire Propogator & A3 Highly flammable🔥💥- fire Propogator & Explosive (such as Butane R270, Isobutane R600a). 


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"

**Suuply 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) & A3 class flammable 🔥 / explosive 💥 (R270, R600a) refrigerants, that requires extra risk assesment, extra safety, extra handling certification (C&G 6187-21), Supply Chain diciplines includes:
Local Authorities, Trade & Industry Associations (ACRIB, BRA, HEVAC, BESA, IOR, CIBSE, RIBA, HHIC, ACTUATE), Distributors & Wholesalers, Publishers, Advertising Agencies, Insurance companies, Government Departments,Transport, Building Users & Owners, all need to ONLY use, specify or support manufacturers who comply and abide by the 11 clauses of the CCPI code, to ensure their customer's safety and the Supply Chain credibility & integrity. 
Manufactures should & must  embrace The Code to confirm their published or unpublished corporate ethical claims to gain the confidance of the Supply Chain.

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?. 

R410A is an A1 class non-flammable refrigerant is the dominant refrigerant in the world while 🔥 R32 has been since 2015   

  
6Public 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, etc
