R32 Refrigerant

  


R32, is a single component refrigerant that has zero ODP gas with a GWP of 675, and classified as A2L (flammable) under ISO 817 & ASHRAE Standard 34 classifications.

R410A Classified as A1 non-flammable refrigerant has Zero ODP with a GWP of 2088 is a mixture of R32 and R125 (R125 acts a suppresnt to R32's flammability).

Refrierants used in a DX (direct expansion cycle) are circulated to perform efficient energy transfer from inside to outside (cooling() and outside to inside (heaing). The only release to the atmosphere is due to accidental leaks where F-Gas regulation needs to be adhered to as it is primarily and Environmental qualifications for engineers ensuring Environmentally safe handling of refrigerant.

F-Gas CAN NOT cover any competencey on personal or project safety. Personal safety for A1 & A2L refrigerants require City & Guilds 2709 & 6187-21 or equivelent. Project safety need BSEN378 .


R32 Is it Flammable? YES Is it Permanent? NO (2023?)

Is it covered by Standard HSE? NO (Need DSEAR)

High GWP 2088 'IF LEAKED' BUT IT'S NON-FLAMMABLE. Class A1
 
Covered by HSE and Building & Fire codes
 
Currently R410A (non-flammable) refrigerant for all systems (Splits, Multi Split and VRF) since 2004.
 
No bans (except on sale of split systems with a total charge of less than 3kg by 2025 with 4 year extension if there are technical or safety issues) .[see F-Gas ban]
 

 

Low GWP of 675 'IF LEAKED' BUT IT'S FLAMMABLE. Class A2L
 
It is not covered by Building & Fire codes.
 
It is not covered under the currant non-flammable HSE. Risk Assesment must be carried out under UK DSEAR or European ATEX

Labeling is mandatory 
and helps awarenace

 


 

Installers / Employers / Owners carry the ultimate legal safety responsibility 


 

Internationa ISO 817 l & ASHRAE Refrigerant Classification


Important:  F-Gas have nothing to do with flammable or non flammable. It set targets to reduce GWP of refrigerants 

For A2L installer Personal Safety you need:  City & Guilds 6187-21 or equal and approved.

See F-gas Bans and LG Recommendations


It is the responsibility of the installer to ensure equipment have clear labeling and warning that are transparent to end-users, and emergency services. Building owners must ensure that their insurance providers are aware of the risks associated with flammable refrigerants. All are responsible under DSEAR regulations

FACTS :                                                           


the final solution? :

There two regulations that affect the reduction (phasing down not out) of ALL HFC refrigerants with high or low GWP.

The  European F-Gas and the International Kigali Amendments to Montreal Protocole.(also called Paris accord)
