Analyse and service HVACR systems

Assessment tool

Version 1.0
Issue Date: May 2024


The unit applies to HVAC/R technicians in manufacturing, servicing and maintenance enterprises. The unit applies to existing HVAC/R control systems and does not cover the design of new HVAC/R systems.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

This unit of competency covers the skills and knowledge required to analyse and evaluate heating, ventilation, air conditioning and refrigeration (HVAC/R) control system requirements for a specific application.

This includes evaluation of existing automatic control systems; interpreting and producing control diagrams; commissioning, fault-finding and repairing a HVAC/R control system.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

MEM23004A

Apply technical mathematics

MEM23006A

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

demonstrate essential knowledge and skills to analyse and service HVAC/R control systems

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

demonstrate analysing and servicing HVAC/R control systems consistently in 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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
