Design of plantrooms for A2L refrigerants

The uptake of equipment using flammable A2L refrigerants raises questions that plantroom designers, familiar with HFCs and other non-flammable refrigerants, have not previously faced.

Risks of an A2L installation must be considered, using the AS/NZS 60079 family of standards, in the same way as for other flammable refrigerants. Failure to undertake a proper hazard assessment, or to ignore the flammability of A2Ls at the design stage, may lead to dangerous or illegal installations requiring expensive rectification.

This presentation will highlight issues that plantroom designers may not previously have faced, and approaches to achieving an economical and safe design.
