Unit of competency
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

Assessment requirements
Modification History
Release 1. Supersedes and is equivalent to MEM23147A Contribute to the design of hydronic systems.
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:
- identifying and interpreting drawings, client requirements and specifications appropriate to the design task
- implementing work health and safety (WHS) procedures and practices including the use of risk control measures
- demonstrate the use of software tools related to designing a hydronic system
- contributing to the design of a hydronic system on at least two occasions including determining performance aspects of the systems, sizing pipes, selecting optimum pump performance, minimising system friction losses and selecting major components and materials using manufacturer data
- communicating technical and procedural requirements to others
- dealing with unexpected situations
- documenting technical information and designs in accordance with procedures.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.
Knowledge Evidence
Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:
- WHS requirements
- appropriate personnel to consult
