Description
This unit involves the skills and knowledge required to select commercial refrigeration system equipment, components and accessories.It includes selecting commercial refrigeration system equipment and components, pipe work and controls. It also includes selecting refrigerant, condensing unit, evaporator, refrigerant controls, accessories, refrigerant and condensate pipe work, and system controls based on specifications, industry standards and manufacturer catalogues to determine calculated and deemed-to-comply solutions and documenting all selection information.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.
