AIRAH refrigeration resources

AIRAH is recognised by industry and government – in Australia and internationally – as an authoritative source of information about refrigeration and refrigerants.

Gathering independent scientific and technical knowledge in every sector of refrigeration, AIRAH advocates proactively with bodies that develop associated regulations, codes, and standards.

AIRAH and our international partners share their collective knowledge and experience on committees and task forces to educate members and the wider industry on various aspects of refrigeration.

With a commitment to disseminating knowledge of refrigeration to improve the quality of life for all, AIRAH does this while respecting the environment, considering economic imperatives, and taking action to implement sustainable refrigeration in all its applications.

We invite you to explore these refrigeration resources below and to get involved with our Refrigeration Special Technical Group (STG).
