Psychrometrics unveils the physical and thermodynamic properties of gas-vapour mixtures.

Do you rely on your computer output for this information? Understanding psychrometrics and its application is a crucial component of good HVAC design.

Use the chart to understand a range of air conditioning processes and considerations. Use that understanding to verify computer modelling and heat load calculations.

This practical course will teach you how to read a psychrometric chart, plot air conditioning processes, and calculate supply air quantities and temperatures.  Real world examples will be analysed and worked through.

This course is provided face-to-face, as well as online, with the option online to study either Psychrometric Theory and Psychrometric Processes, or both.



Psychrometrics (Face-to-face)

Key topics

  • Basic calculations and chart plotting
  • Mixing of air streams
  • Typical air conditioning systems
  • Use of ratios for plotting SH/LH/TH
  • Psychrometrics and human comfort
  • Real world examples

Designed for

  • Graduates who need to learn psychrometric principles
  • Engineers to refresh their knowledge


               John Bosci, F.AIRAH, worked in the building services industry for close to 40 years. John began in contracting as a draftsman, moving to site engineer, construction supervisor, design and construct tendering, and building. He then moved to an engineering consultancy and progressed from design engineer to office manager and finally to CEO, with responsibility for 17 offices throughout Australia and South-East Asia.

John’s personal experience includes a wide range of projects, including hotels, hospitals, high-rise offices and casinos. The diversity of John's business and cultural experiences, together with the often disparate geographical locations, required broad knowledge in a range of air conditioning approaches, together with a detailed exposure to specific psychrometric needs.

Cancellation and refund policy

Registration may be cancelled up to five working days prior to commencement of the course with participants either transferring to another course / event or receiving a refund less a 20% administration fee. No refund will be given where cancellation is 24 hours or less. In all other cases of cancellation the extent of any refund will be at the discretion of AIRAH.

You may substitute another participant at any time prior to the event date should the nominated person be unable to attend. Where the course has entry requirements these must be met by any substitute participant. Where a non member replaces a member the difference between member and non member rates will be charged.
