Description
This unit of competency defines the skills and knowledge required to use air flow and distribution principles used in heating, ventilation, air conditioning and refrigeration (HVACR) systems and to identify different system configurations to design a single, one-air distribution system and service-related system components. The system is designed to meeting environmental and cost control requirements.A single zone duct distribution system is a basic central system which supplies a constant air volume, or a variable air volume, at low, medium or high pressure through a single duct.The unit is suitable for people working as supervisors, technicians and HVACR 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.
