Modification History
Release 1 (MEM05v9).
Unit Descriptor
This unit of competency covers the knowledge and skills required to contribute to the design of hydronic systems or for less complex systems to undertake the complete design. The unit includes analysis of characteristics of water flow in a given pipework system; selection and sizing of pipes, fittings, suitable pumps, and associated fittings and valves.
Application of the Unit
The unit applies to heating, ventilation, air conditioning and refrigeration (HVAC/R) technicians in manufacturing, servicing and maintenance enterprises required to undertake design work on hydronic systems. The unit applies to design work undertaken as part of a design team comprising engineers and other technicians and to individual design tasks within the technician’s skill and knowledge.
Licensing/Regulatory Information
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
