This section describes the skills and knowledge required for this unit.

Required skills 

Required skills include:

• interpreting client requirements and specifications
• determining performance aspects of heat exchanger
• interpreting current codes and regulations
• selecting major system components and materials using manufacturer's data
• using relevant software tools effectively
• interpreting drawings and specifications
• communicating effectively with others
• communicating technical and procedural requirements to others
• documenting technical information and designs
• dealing effectively with unexpected situations
• working in teams and with others

Required knowledge 

Required knowledge includes:

• thermodynamic principles
• heat transfer
• refrigeration/heat pump parameters
• airflow parameters and measurement of airflow
• calorimetric measurements
• measurement of temperature

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently:

• implement WHS workplace procedures and practices, including the use of risk control measures as specified in the performance criteria and range
• demonstrate essential knowledge and skills to design heat exchanger systems
• demonstrate competency within a timeframe typically expected of the discipline, work function and industrial environment
• demonstrate the design of heat exchanger systems consistently.

Context of and specific resources for assessment 

• This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations.
• The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

Method of assessment 

• Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
• Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
• Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
• Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
• Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
• Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

• elimination or control of excessive noise
• use and recycling of refrigerants
