Unit of competency
Modification History
Release 1. Supersedes and is equivalent to MEM23146A Contribute to the design of industrial refrigeration systems.
Application
This unit of competency defines the skills and knowledge required to contribute to the design of industrial refrigeration systems or to undertake the complete design for less complex systems. It includes the determination of the specific type of system and selection of major system components and materials using manufacturer data to determine performance aspects of systems for a given application.
The unit applies to technicians in organisations that design whole refrigeration systems or design modifications to existing systems, including systems incorporating multiple evaporators and compressors, moderate and low temperature, indirect refrigeration and flooded systems.
It applies to design work undertaken as part of a design team comprising engineers and other technicians and to individual design tasks within the scope of the technician’s skill and knowledge.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Pre-requisite Unit
MEM23004 Apply technical mathematics
MEM23006 Apply fluid and thermodynamics principles in engineering

Performance criteria describe the performance needed to demonstrate achievement of the element.
|
|
1. Determine design specification and select components for an industrial refrigeration system
|
1.1 Obtain and implement work health and safety (WHS) and environmental requirements for the work area
1.2 Determine design requirements from client requirements, job specifications, briefings and/or discussions with appropriate personnel
1.3 Identify and interpret relevant codes and standards
1.4 Consult with appropriate personnel to ensure that work is coordinated effectively with others
1.5 Obtain equipment and resources needed for the task in accordance with organisational procedures and check for correct operation and safety
|
|
2. Design system
|
2.1 Select the most suitable design for an industrial refrigeration system to meet the specified requirements

2.3 Check system design draft for compliance with the design brief, regulatory requirements and environmental standards
|
|
3. Analyse and adjust system performance
|
3.1 Analyse system performance under variable conditions against client design brief and adjust component selection to meet performance criteria
3.2 Determine fulfilment of required capacity under full and partial load conditions using appropriate resources
|
|
4. Validate system design
|
4.1 Verify final design using organisational procedures for compliance and regulatory requirements
4.2 Document final system design for client approval, using appropriate equipment to industry standards
|
