Description
This unit of competency defines the skills and knowledge required to coordinate servicing and fault-finding of heating, ventilation, air conditioning and refrigeration (HVACR) environment control systems. It includes content about work health and safety (WHS) and related safety compliance requirements, performance analysis software and validation, and related thermodynamic concepts and laws. The control system can be a part of a building management system and may be a control system in industrial or commercial refrigeration, a hydronic system or food storage technology.This unit applies to technicians, system managers, designers and draftspersons, and others who are required to coordinate the servicing and fault-finding of HVACR control systems, including undertaking required technical analyses and coordinating and supervising tradespersons or other technicians. No licensing, legislative or certification requirements apply to this unit at the time of publication.
