Modification History

Release 1. Supersedes and is equivalent to MEM23140A Determine operational parameters for building HVAC hydronic systems.

Application

This unit of competency defines the skills and knowledge required to identify fluid flow and distribution characteristics of hydronic systems and measure system component performance, including chillers, boilers and flow control devices.

The unit applies to technicians required to determine features and performance of heating, ventilation and air conditioning (HVAC) hydronic systems, including performance and characteristics of components, piping and the overall system. It applies to design, manufacture, installation or servicing work in HVAC enterprises.

The unit is suitable for people working as, supervisors, technicians, and HVAC draftspersons, and for those pursuing manufacturing engineering or related technical qualifications and careers.

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

Pre-requisite Unit
