New DA manuals focus on commissioning

The Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH) is releasing two Design Application (DA) manuals focusing on air distribution systems and hydronic water systems.

DA04 Air System Balancing – in HVAC is a new release in AIRAH’s collection of technical resources. The manual discusses the testing, adjusting and balancing (TAB) of air distribution systems in HVAC&R applications. It also promotes best practice for the balancing of air distribution systems in the industry.

DA24 Hydronic System Balancing – in HVAC is a revised and updated Design Application manual, which focuses on the testing, adjusting and balancing of hydronic water systems. The previous version of this technical resource was titled DA24 Water Systems Balancing.

“A number of AIRAH members made these manuals possible with their contributions,” says AIRAH’s Education and Technical Services Manager, Brendan Pejkovic, “including the lead author, William Lane, F.AIRAH, and editor Vince Aherne, F.AIRAH,”
