Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

MEM23142 - Determine psychrometric processes and system performance

What evidence can you provide to prove your understanding of each of the following citeria?

Review psychrometric processes

  1. Obtain and implement work health and safety (WHS) and environmental requirements for the work area
  2. Apply knowledge of psychrometric processes to analytical solutions to HVACR systems in accordance with organisational procedures
  3. Diagnose air temperature and humidity problems using psychrometric charts
  4. Consult appropriate personnel to ensure that work is coordinated effectively with others

Analyse the psychrometric and system performance of HVACR systems

  1. Determine plant or system capacity and airflow requirements for effects of coil bypass factor, apparatus dew point (ADP) and partial load control
  2. Calculate dehumidified air quantity using both target superheat (TSH) and effective room sensible heat (ERSH) methods
  3. Establish plant capacity and air flow rates for the system and/or building
  4. Establish airside systems and determine system performance
  5. Determine systemic performance parameters
  6. Consult on any contingencies and unexpected situations and take appropriate action based on specifications, codes and standards, and organisational procedures
