UEERA0018 Design complex commercial refrigeration systems and select equipment

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 complex commercial refrigeration systems and select equipment. It includes applying processes and methods of complex commercial refrigeration systems, safety and relevant industry standards; developing alternative design schemes based on a design brief and customer requirements; and documenting system designs. 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.
