Contribute to the design of heating systems

This unit of competency covers the skills and knowledge required to contribute to the design of appropriate heating equipment to provide optimum performance or for less complex systems to undertake the complete design. The unit includes determination of best piping configurations and system pipe sizes, taking into account thermal heat losses.

Application

The unit applies to manufacturing, servicing and maintenance enterprises incorporating refrigeration and air conditioning design, manufacture and installation.

WHS and environmental requirements relevant to heating systems

Evidence Required

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 heating systems

demonstrate competence within a timeframe typically expected of the discipline, work function and industrial environment

demonstrate the design of a heating system consistently for different applications.

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.
