What is Refrigerant? What are Refrigerant Specification & Safety Classifications?

Refrigerants are chemicals with unique thermodynamic properties advantages, have very low boiling temperatures, and can carry 10 times more energy per weight than water and 50 times more than air.

There are over 300 types of refrigerants in THREE flammability classifications Classifications (A1, A2/A2L, A3) in accordance with ISO 817:2014 (E) & ASHRAE Standard 34 International Standards.

          

What is A2L class R32? & Who introduced it?  

HFC R32, as a  "SINGLE COMPONENT** is an A2L class flammable refrigerant, introduced by Daikin Industries*1 in Japan in 2012 and 2015 in Europe as a low GWP TEMPORARY short term substitute for A1 class non-flammable HGWP Refrigerants for small splits with up to 3 kg system charge ONLY. *1Note: Daikin hold 180 Patents relating to R32 which licensed to other manufacturers (Japanese, Korean, Chinese etc manufacturers) (see Cartel)

**Note:    R32 is an important component in many A1 class non-flammable  Zeotropic mixture such as R410A (50% R32, 50% R125). R407C and many existing & future. A1 class refrigerants has been used in AC in public and residential buildings since 1928.

Manufacturers,

Distributors,

 & Importer's

OBLIGATIONS

 

a) Manufacturers, Authorised Representatives, Importers and Distributors are under Duty & Obligations to meet the following, including CE marking (and upcoming UKCA) and Labelling.

  

b) Manufacturers & Economic Operators must follow Code of Practice for consumer Products Safety related Recalls and Other corrective actions. 

 

c) Marketing materials ( Sales leaflets, advertising, websites etc) must follow Advertising Standards "The CAP Code".

  

Specifiers &

Building Manager's

Obligations

 

a)  Specifiers, designers of building services, needs to take into account H&S 2016 no.1107 Statutory Requirements when using A2L or A3 class refrigerants in Public Buildings1 & request certificates from manufacturers.

b) Managers and Owners of Public Buildings1 responsibilities to the occupiers fall under strict compliance with the new Building Safety Regulations and BSI Standards. Risk Assesments to take into account the PROXIMITY of Equipment in a fire zones.

c) End Users Need to be MADE aware of the restrictions in the use and operation of equipment containing A2L class flammable refrigerants and given a choice.

d) AC equipment selection for any Building needs to take account the long term serviceability and availability of spares and refrigerant availability.. e.g. A1 class R410A non flammable willl be at least till 2040

 

Installer's

Obligations

 

Installers, Designers, Building Managers and Owners of Public Buildings1 responsibility fall under 

     a) Written confirmation from Manufacturers, Distributors, importers that products containing flammable R32 meets H&S 2016 no.1107 & meets Code of Practice PAS 7100:2018

 

    b) Installation & maintenance companies  meets manufacturers recommendations

  

    c) Installer should be qulified and certified to handle (A2/A2L) flammable refrigerants e.g. City & Guilds 6187-21   in addition to City & Guilds 2079-11,12) & F-Gas certification

 

Important:  F-Gas certification of engineers does not cover any competency on personal or project safety. It sets targets to reduce GWP of refrigerants by safe practice.(worthy to note that F-Gas certification is NOT the EU F-Gas Regulation)
 

Authorised Installers who are manufacturers direct partners are part of the economic operator chain & must ensure the project meets H&S and F-Gas installation legal & safety requirements as they could be liable for damages for the  loss of life or property.

End Users

 

End users and occupiers must be clearly be informed of the class of refrigerant (A1, A2L, A3), to be made aware of risks associated with flammable A2L class or explosive A3 class refrigerant before installation and at the quotation stage.

  


 Did you know?

- A2L class flammable R32 is a component of some A1 class non-flammable refrigerants (e.g. R407C [R32+R134a+R125], R410A [R32+R125]), and has been around more than 20 years to replace A1 class non-flammable  HCFC22 due to its ODP( Ozon Depletion Potential). The mixture with R125 for example is to suppress the flammability of R32 to qualify as an A1 class non-flammable, for safe use in Public & Residential Buildings1.

- A2L class flammable R32 is a  short term refrigerant with a low GWP of 675 (if leaked), introduced by Daikin with the intention (falsley?),to replace, according to (EU Rule)the current A1 class non-flammable R410A (GWP 2088) in small Split Systems,with a charge of less than 3kg. This is not until 2025 & with exemptions. (This will change after the 1st January 2021 as the UK is following Montrael / Kigali international protocole the the revision of F-Gas Regulations )

- A2L class flammable R32, It is claimed that as a single component, per weight can carry more energy (aprox 5% depending on temperatures) than R410A is not true as in practice due to the high discharge temperatures (20°C+) and high missability with oil, these forced manufacturers to a) Reduce refrigerant quantity, b) Increase compressor speed & c) Adjust and limit operation due to the flammability and possibility of explosion (click Diesel effect). These measures to meet nominal standard capacities. (see Daikin Chemical document)

 

        

- A2L HFC R32 charged refrigeration cycle can explode? YES If (Called Diesel Effect) watch video

         a) If air or moisture remains in the system ( inaccurate vacuuming), that might ignite the oil during compression cycle.  [R32 discharge temp is 20°C higher than R410A].  b) If the system is in the proximity of a fire         

                   

             


UK Government view for not committing to flammable refrigerants:
 

UK Government Study of the impact of high GWP 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)

The upcoming Building Health & Safety revision (a result of Grenfell Tower disaster) will BAN the use of FLAMMABLE materials in Public & Domestic buildings1.


Why & Who Indroduced A2L R32 as a single component?

Why, introduced as a single component? The false argument is that it has Low GWP( Greenwash*) if leaked!, but, forgetting!! to mention the possible consequences, being flammable, when leaked?. Intentional Greenwashing* of the fact that flammables (A2 or A2L) never been used in Public or Residential Buildings since 1928. A2L R32 does not meet UK or International safety regulations,

Who,  Daikin Industries manufacturers of AC equipment & Chemicals 1st introduced flammable refrigerants A2L class R32 as single component in 2015 in Europe and registered 180  patents regarding R32, which they licenced to other manufacturers  Business Cartel

Note: According to Daikin Chemicals page 12  "under Japan‘s High Pressure Gas Safety Act, it is not classified as a flammable gas?"(It does not however states it is non-flammable?!) challenging   ISO 817 & ASHRAE 34, standards
 

Daikin and other manufacturers in the Cartel are refusing to supply/confirm necessary certification to comply with Directives such as ATEX 34/2014 or H&S 2016 no.1107 and Statutory Instrument or meet Advertising Standards "CAP Code" ?

 

 Space Air say: It is a shame that A2L R32 is being forced on the UK and some EU countries by a manufacturer, Space Air promoted for 36 years as the true innovator and leader. Unfortunatly Daikin Industries under their chairman Mr. Noriyuki Inoue deceptivley introduced R32 in Japan in 2012 & 2015 in EU. 

The introduction of R32 in Japan was done on the basis that R32 is not flammable (simply because Japan Gas regulations do not classify R32 as flammable, but it does not consider R32 is non-flammable! either?). The system in Japan simply (which worked for their success over decades) rely on honesty of leaders, a normal phenomena in Japan)? (see Daikin Chemical document page 12).

Mr. Inoue, used Daikin Industry strength in innovation and trust (Space Air supported and promoted since 1980), to monopolize the patents (180 no.) in the use of R32 as a single component and deceptively promoted them to other Japanese, Korean and Chinese manufacturers and forced them to follow Daikin patents guidelines creating a Business Cartel , Greenwash*

 

Daikin under Mr Inoue's vision, continued with the deception, not only in Japan but Europe also, taking advantage of the fact no one will ask if A2L class is flammable or not?, (AC industry never used flammables in domestic AC since 1928) and the fact that Daikin is no. 1 and have Chemical Interest manupilated EU legistlators to adapt & monopolised the EU quota (Daikin have 28 quota out of 200) system which is under revision as it has been abused and the EU wants to alline its policies with the Kigali amendment to the Montrael Protocol..

The Business Cartel starved the UK (while part of the EU) and EU market in order to promote the sale of uncertified equipment charged with A2L class flammable R32, which lead to the hiking of prices of A1 class non-flammable refrigerants in 2017/2018 (e.g. R410A from £14/kg to over £80/kg) knowing very well that any EU ban will not apply till 2025 and only for splits systems charged with upto 3kg (click for details)

Life (in any form) is more important than commercial deception and false claims


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

Public Buildings1 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, Care homes,
