Overview

This unit covers the determination of basic operating conditions of air conditioning systems. It encompasses working safely, determining air temperature, air flow rates and relative humidity using measurement and basic calculation methods.

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

  • terms used in the study of air;
  • sensible heat, latent heat and total heat;
  • sensible heat ratio;
  • plotting basic points on a chart;
  • reading additional information, and;
  • values relevant to a plotted process and plotting a simple process on a psychrometric chart.

T6 Basic air conditioning processes

  • factors effecting human comfort;
  • industry recognised human comfort conditions;
  • the comfort zone, and;
  • basic processes used to obtain comfort conditions.

T7 Ventilation

  • basic needs for ventilation;
  • methods used to ventilate an area, and;
  • typical applications for ventilation systems.

T8 Regulations

  • covering ventilation;
  • common council requirements/regulations, and;
  • fresh air requirements for typical situations.

T9 Heat loads

  • sources of sensible heat in an air conditioned space;
  • sources of latent heat in an air conditioned space;
  • changes in sensible/latent ratios and their effect on operating system capacity;
  • industry check figures;
  • basic room heat load calculation using check figures, and;
  • basic RAC/split system unit selection.
