Description
This unit of competency defines the skills and knowledge required to evaluate thermal load estimates for heating, ventilation, air conditioning and refrigeration (HVACR) systems in multiple zone commercial/industrial buildings and engineering facilities, commercial refrigeration systems and related installations. It includes consideration of work health and safety (WHS) and related safety compliance requirements, and system evaluation, including the use of software and validation, thermodynamic concepts and laws.It is suitable for people working as technicians, system designers, draftspersons, maintainers, and 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.
