MEM23147 Contribute to the design of hydronic systems

Modification History

Release 1. Supersedes and is equivalent to MEM23147A Contribute to the design of hydronic systems.

Application

This unit of competency defines the knowledge and skills required to contribute to the design of hydronic systems or to undertake the complete design for less complex systems. It includes analysis of characteristics of water flow in a pipework system, and selection and sizing of pipes, fittings, suitable pumps, and associated fittings and valves.

The unit applies to heating, ventilation, air conditioning and refrigeration (HVACR) technicians in manufacturing, servicing and maintenance enterprises required to undertake design work on hydronic systems.

It applies to design work undertaken as part of a design team comprising engineers and other technicians and to individual design tasks within the scope of the technician’s skill and knowledge.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Pre-requisite Unit

MEM23004 Apply technical mathematics

MEM23006 Apply fluid and thermodynamics principles in engineering

MEM23140 Determine operational parameters for building HVAC hydronic systems

Competency Field
