The Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH), with support from the ARBS Foundation, is revising its DA17 application manual to improve the efficiency and safety of cooling tower systems.
Evaporative cooling towers play a crucial role in HVAC&R and industrial cooling. However, the existing DA17 manual, which is over a decade old, requires updates to reflect technological advancements and regulatory changes. The revised DA17 will continue to focus on wet-type evaporative cooling towers while also addressing hybrid, dry, and adiabatic pre-cooled systems, as well as alternative heat rejection methods such as air-cooled and natural heat sinks.
Key updates to DA17 will include:
- Industry-derived energy protocols to enhance efficiency in evaporative cooling towers.
- Revisions to align with current industry developments, including regulatory updates, risk assessment improvements, and advancements in tower technology and cloud-based system management.
- Updates to AS/NZS 3666 compliance to ensure adherence to the latest standards.
- Enhanced guidance on energy and water efficiency for both new and existing cooling towers.
The manual serves as a key resource for system manufacturers, designers, installers, maintenance providers, and end-users, including system owners and operators. With these updates, AIRAH aims to support best practices in cooling tower applications while promoting sustainability in the HVAC&R industry.
