Follow us       Contact us   

  


Space Air are under obligation to meet H&S 2016 No. 1107 Statutory Instrument to not supply equipment containing A2L flammable refrigerant without conforming to Part 2 of the Statutory Instrument. All equipment supplied by Space Air will contain A1 class non-flammable refrigerant. Classifications are in accordance with ISO 817 and ASHRAE 34 Standards.


 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.         (see Facts about Refrigerants)


Refrigerant Standards & Classifications There are THREE refrigerant Classifications (A1, A2/A2L, A3) with regards to  flammability, in accordance with ISO 817:2014 (E) & ASHRAE Standard 34 International Standards (click on images for more info..)

 

  


What is A2L class R32? When & who Indroduced it? Is it Safe? Is it Legal? (see did you know below)

When & Who Indroduced it? & Why?

HFC R32 is single component* A2L classified flammable refrigerant, introduced by Daikin Industries in Japan in 2012 and 2015 in Europe as a low GWP substitue for A1 class non-flammable R410A (Current legal & safe refrigerant) . A1 class refrigerants has been used in AC in Public and Residential1 Buildings since 1928.

Why introduced as a single component? The fales argument is that it has Low GWP if leaked!, but, forgeting!! to mention the possible consequances, being flammable, when leaked? (see is it safe). Intentional ignorance 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,

Daikin Industries manufacturers of AC equipment and Chemicals who 1st introduced flammable refrigerants A2L class R32 as a single component in 2015 and owned patents regarding R32, sold to other manufacturers  Business CartelAccording to Daikin Chemicals (page 12)  "under Japan‘s High Pressure Gas Safety Act, it is not classified as a flammable gas" chalanging   ISO 817 & ASHRAE 34, standard, hence refusing to obtain necessary certification to meet Directives such as ATEX 34/2014 and H&S Statutory InstrumentA2L class R32 is a  short term refrigerant and intended to be replace by 2023?!! (MUST WATCH VIDEO).


Is it Legal and Safe? NO unless you meet the following:

 A2L class R32 is a Flammable refrigerant and requires:  (click on any image for further details)

a) Manufacturer, Importer, Distributor legal obligations ,to meet  H&S 2016 no.1107 Stautory Instruments, and BEIS (Department for Business, Energy & Industrial Stratiegy) UK Statutory Guidance 2016 published August 2017. (both instrument & guidlines are in line with ATEX 34/2014/EU . 

  

b) Extra Engineer Safety qualifications in handling A2/A2L & A3 refrigerants 

c) Extra Installation Safety and material cost IF IT MEETS a) above:  components for A2L Flammable. (ventilation, alarms, pipe protection electrical installation and location of equipment). The following are manufacturers recomendation

  

d) Extra End Users awareness End users MUST be Informed of compliance and risks & ristrictions by giving them User Manual (example of various major manufacturers). It is the specifier and installer responsibility to insure compliance with a) above

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) Multiple Sytems within a Building needs to be of one type of refrigerant to insure compliance, life cycle security and reduce multiple dicipline maintenance.

e) AC equipment selection for any Building needs to take account the long term servicibility 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.

Authorised Installers who are manufacturers direct partners are part of the economic operator chain & must insure 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.

- Clearly, A2L or A3 class Flammable refrigerants have NO place in Public or Residential Buildings1..

- A1 class refrigerants have been available and used safely since 1928. Many options of A1 class available (see ASHRAE 34 & ISO817)

-The disaster of Grenfell Tower has highlighted the irresponsible behaiviour of manufacturers, suppliers and economic operators in supplying products containing flammables.

- Having flammable refrigerants in home refrigerators (A3 Class, such as Butane R600 of Isobutane R600a) or A2L class R32 in air conditioning and Heat Pump systems used in Public & Residential Buildings1 is illigal, unethical and criminal.

- Cartel manufacturers operating in the UK supply A1 class non-flammable R410A everywhere els in the world! ? but playing games and supply of equipment charged with UNCERTIFIED R32 A2L class  FLAMMABLE refrigerant!

 

UK Government view for not commiting to flammable refrigerants:

UK Government Study of the impact of high A1 class GWP 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, costs and uncertinity of A2L class flammable refrigerants (e.g. R32) as a viable long term refrigerant. 

The upcoming Building Health & Safety rivision (a result of Grenfell Tower disaster) will BAN the use of FLAMMABLE materials in Pub;ic & Domestic buildings. 


 Did you know?

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

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

- A2L class R32, 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 discahrge temperatures (20°C+) and high missability with oil, these forced manufacturers to a) Reduce refrigerant quantity, b) Inrease compressor speed & c) Adjust and limit operation due to the flammabilit and possibility of explosion (click Diesel effect) and d) To meet nominal standard capacities. (see Daikin Chemical documet)

    

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

 a) If air or moisture remains in the system ( in accurate vacumeing proccedure), 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

                        


 Space Air say: It is a shame that A2L R32 is being forced on the UK and some EU countries by a manufacturer, I promoted for 36 years as the true innovator and leader. Unfortunatly Daikin Industries under their chairman Mr. Inoue introduced R32 in Japan in 2012 & 2015 in EU. The introduction of R32 in Japan was done on the bases that R32 is not flammable (simply because Japan do not such regulations, and rely own honesty of leaders, a normal phenomena in Japan)? (see Daikin Chemical document page 12). Inoue, used Daikin Industry strength in innovation, monopolized the patents (180 no.) and deceptively sold them to other Japanese, Korean and Chinese manufacturers and forced them to follow Daikin patents guidelines creating a Business Cartel , Then manipulated the EU legislators to adapt the EU quota system (which is under revision by Dec 2020 due to abuse and not matching International environmental agreements such as Kigali amendment.The Business Cartel starved the UK and EU market by monopolising the EU Quota system to promote the sale  of uncertified equipment charged with flammable R32.That lead to the hicking of prices of A1 class non-flammable refrigerants (e.g. R410A from £14/kg to over £80/kg in 2017/ 2018)

Space Air will meet its Obligations as stated in H&S 2016 no.1107 as a distributor since 1980! eithicaly, and will not supply uncertified air conditioning equipment containg any flammable refrigerants. We have options and legal solutions to ensure safety of our customers and USERS. Space Air are also registered with BSI PAS 7100:2018 

We ask Goverment Departments, Legislators, Archetects, Specifiers, Associations (UK and world wide), Manufactures, Contractors, Building Owners & Operators, and Users to ask and demand answers to a simple quotion "Does the equipment or anything, uses A1, A2/A2L or A3 class REFRIGERANT ?". Simple, safe, responsible and lawful. Refuse to accept equipment charged with A2L or A3 class refrigerant unless it conformes with Part 2 of H&S 2016 no.1107. There are many safer A1 class  options Neil Afram F.M.Inst.R.

Life (in any form) is more important than commercial stunts.


 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,
