Description
This unit of competency defines the skills and knowledge required to identify psychrometric processes and determine system performance in a commercial building. It applies to those in organisations designing, manufacturing, installing, servicing or maintaining heating, ventilation, air conditioning and refrigeration (HVACR) equipment.It is suitable for people working as supervisors, technicians and HVACR draftspersons, and for those pursuing manufacturing engineering or related technical qualifications and careers.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Review psychrometric processes
  • 1.1 Obtain and implement work health and safety (WHS) and environmental requirements for the work area
  • 1.2 Apply knowledge of psychrometric processes to analytical solutions to HVACR systems in accordance with organisational procedures
  • 1.3 Diagnose air temperature and humidity problems using psychrometric charts
  • 1.4 Consult appropriate personnel to ensure that work is coordinated effectively with others
2. Analyse the psychrometric and system performance of HVACR systems
  • 2.1 Determine plant or system capacity and airflow requirements for effects of coil bypass factor, apparatus dew point (ADP) and partial load control
  • 2.2 Calculate dehumidified air quantity using both target superheat (TSH) and effective room sensible heat (ERSH) methods
  • 2.3 Establish plant capacity and air flow rates for the system and/or building
  • 2.4 Establish airside systems and determine system performance
  • 2.5 Determine systemic performance parameters
  • 2.6 Consult on any contingencies and unexpected situations and take appropriate action based on specifications, codes and standards, and organisational procedures
3. Document and report on psychrometric and HVACR system performance
  • 3.1 Evaluate solutions to psychrometric and system performance to determine their effectiveness
  • 3.2 Report and document analysis in accordance with organisational procedures, incorporating details of all findings, calculations and assumptions
  • 3.3 Prepare and justify recommendations for any required actions in relation to HVACR equipment
