Unit of competency
Modification History
Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package. |
Application
This unit involves the skills and knowledge required to design commercial refrigeration systems and select components. It includes applying processes and methods of refrigeration and food storage technology, refrigeration system components and piping, and safety and regulatory requirements. It also includes following design specifications and customer requirements, documenting system designs and obtaining approval for engineering computer applications design. The skills and knowledge described in this unit may, in some jurisdictions, require a licence or permit to practice in the workplace subject to regulations for undertaking refrigeration and air conditioning work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations. No other licensing, legislative or certification requirements apply to this unit at the time of publication. |
