AIRAH has released the third edition of its design application manual DA01: Centrifugal pumps. DA01 was originally published in 1979; it was updated in 1998 and again this year, to keep step with the ever-changing HVAC&R industry.

“This edition builds on previous editions, with a new focus on optimising pump system design and installation,” says AIRAH CEO Phil Wilkinson, M.AIRAH. “DA01 is the most comprehensive technical resource available for Australian HVAC&R pumping applications. It is an important reference for anyone involved in the design, selection, installation, operation, maintenance, and assessment of pumps and pumping systems.”

The most recent incarnation of DA01 was assessed by the industry and edited by a review panel before publication.

“The US Department of Energy estimates that of all the energy consumed by electric motors worldwide, at least 20 per cent is used by pumps, a substantial amount of which are associated with HVAC&R installations,” says DA 01 editor Vince Aherne, M.AIRAH.

“This energy aspect of pumping systems has become a crucial focus for our industry, as clients demand energy-efficient installations and cost-effective pumping solutions.”

The main purpose of DA01 is to standardise and promote best-practice design, installation and management of centrifugal pumps.

“DA01 aims to help improve the sustainability of centrifugal pump applications in the HVAC&R industry by addressing a range of issues, from pump selection to monitoring and maintenance,” Wilkinson says.

AIRAH’s series of design application manuals was created to assist mechanical engineering designers and maintenance engineers with their day-to-day tasks.

AIRAH is reviewing and updating DA09: Air Conditioning Load Estimation, and DA20: Humid Tropical Air Conditioning.

DA09, which is widely used within the industry and is considered one of AIRAH’s most popular manuals, was last updated in 1998. DA20 was updated in 2000. The DA reviews aim to update design information and data, include new energy-efficient technology and practices, and increase the accessibility of the manuals.
