Application
This unit of competency defines the skills and knowledge required to evaluate thermodynamic systems and components including heat exchangers, heat engines, refrigeration, air conditioners and air compressors.
The evaluation can be undertaken as part of a design or system selection process or to assess system condition, sustainability or efficiency. It is suitable for people working as technicians or system designers and draftspersons, and for those pursuing careers and qualifications in engineering or related disciplines.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Pre-requisite Unit
