About HVAC&R Resources

Compiling a list of the HVAC&R industry's companies, brands, products and services for the annual Industry Directory is a big job, but AIRAH does a lot of good work beyond this. With an aim of facilitating professional development, and promoting best practice, safety, and technical integrity, AIRAH produces a swathe of technical resources each year.

These resources cover everything from best-practice and safety guides, to government communications and useful documents - you'll find it all here.

Safety guides

AIRAH Flammable Refrigerants Safety Guide

Blank Image

This is an industry guide on managing the health and safety risks associated with the safe design, manufacture, supply, installation, conversion, commissioning, operation, maintenance, decommissioning, dismantling and disposal of refrigeration and air conditioning equipment and systems that use a flammable refrigerant. This industry guide is required because of the increasing demand for flammable refrigerants due to their low-GWP characteristics. Hydrocarbon refrigerants are broadly available in Australia and various flammable synthetic fluorocarbon refrigerants are available, or are expected to be available, in the near future.


Best practice guides

AIRAH Methods of calculating Total Equivalent Warming Impact (TEWI) Best Practice Guideline

Blank Image

This guide provides a standardised method of calculating Total Equivalent Warming Impact (TEWI) for new, stationary refrigeration and air conditioning systems at the design stage. Its aim is to assist facility operators, designers and industry practitioners to compare the environmental implications of different technical options available to meet their HVAC&R requirements.

AIRAH Water Conservation in Cooling Towers Best Practice Guideline

Blank Image

This document was prepared to assist the owners and operators of cooling towers and evaporative cooling systems in reducing the water consumption of cooling systems while retaining required performance.

The intention is to identify the ways in which a cooling tower consumes water and outline a series of best practice recommendations to assist the tower operator or water treatment service provider in the reduction of overall tower water consumption.

Useful resources
