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 evaluate thermodynamic and fluid parameters of refrigeration systems. It includes working safely, setting up and conducting evaluation measurements, evaluating thermodynamic and fluid parameters from measured parameters, and reporting results for use in design work. 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. Permits may also be required for some work environments, such as confined spaces, working aloft, near live electrical apparatus and site rehabilitation. No other licensing, legislative or certification requirements apply to this unit at the time of publication. |
