Key Areas

  • An Overview of the Makeup and Properties of Dry and Moist Air
  • The relationship between the Mollier Diagram and Psychrometric Chart
  • Measurement of psychrometric parameters
  • Psychrometric processes (including energy and power)
  • Basic system psychrometrics
  • Psychrometric development of common HVAC systems
  • Applying systems psychrometry for component selection and energy assessment

Course Content

To properly design, commission or operate air systems for environmental control (e.g. air conditioning or ventilation systems) it is essential to appreciate the underlying processes that characterise the changes in the air - the psychrometric processes.

  • The basic psychrometric processes (including assessment of energy and power) for heating, cooling, drying and humidifying
  • Step by step development of the psychrometric chart to ensure all lines and curves are understood
  • How room air and simple air systems are plotted on a psychrometric chart
  • The psychrometry of simple air conditioning systems
  • Development and analysis of combined psychrometric processes (such as thermal wheels and heat recovery)
  • Examples of applying the psychrometric chart to full air conditioning and ventilation systems

Learning Outcomes

At the successful completion of the course the delegate should be able to:

  • List out the key factors that are needed to describe air's condition
  • Explain how the condition of the air may be reliably measured
  • Describe and sketch an outline of a psychrometric chart
  • Use a psychrometric chart to plot individual points and processes
  • Undertake energy and power calculations for air processes
  • Apply the chart to identify the requirement for air heating, cooling, humidification and de-humidification
  • Show complete connected air conditioning processes on a psychrometric chart
  • Analyse the operation and energy use of example air conditioning systems using a psychrometric chart and simple calculations

Who Should Attend

This course is aimed at both new and experienced practitioners who need to understand the basis and application of the psychrometric chart for the analysis and design of air-conditioning and ventilation systems to give a thorough grounding in this essential area.
