Essentials of Air Conditioning

Work confidently on HVAC projects


The AIRAH Essentials of Air Conditioning in-house training resources provide the key knowledge required to work confidently on HVAC projects. These interactive training packages offer a range of knowledge and perspectives and can be delivered in-house using a 'mentor' approach, or they are available as face-to-face delivery with trainer.

The Essentials of Air Conditioning are designed for:

  • Graduate design engineers
  • Contractors/installers
  • Sales engineers
  • Engineering students
  • Facility managers




Psychrometric Theory & Psychrometric Processes

Length: 1 day

Psychrometric Theory

Learn how human comfort fits in with the psychrometric chart, how to read the chart, how to plot basic air conditioning processes and calculate supply air quantities and temperatures.

Psychrometric Processes

Use the psychrometric chart to understand a range of air conditioning processes and considerations including equipment heat gains, mixing air streams, sensible heat ratios and calculations for typical air conditioning systems.

Filters, Fans & Duct Sizing

Length: 1 day

Energy efficiency is becoming increasingly important. Filters, fans and sizing of ductwork systems can all impact efficiency as well as the quality of the indoor environment.

Find out how to avoid problems before they show up.


Identify different types of air filters and their uses, select the appropriate air filter for an application, and learn how to interpret air filter test reports.


Select fans and design for their use in air conditioning systems. The course will cover fan types and characteristics, fan control strategies, noise issues and gives an overview of pressure measurements.

Duct Sizing

An introduction to efficient sizing and laying out of ductwork systems. Looks at factors affecting ductwork system design, pressure loss calculation, pressure loss of fittings and procedures for sizing duct systems.

Cooling Towers

Cooling Tower selection

A solid introduction to selection of cooling towers, including an overview of the workings of a cooling tower, identification of different types of cooling towers - and their materials and components, and the considerations for selection of the appropriate cooling tower for an application.

An introduction to what a cooling tower is, and its advantages, the evolution of cooling towers, types of towers, components and materials, and considerations for selecting a tower.

Cooling Towers - Installation, Operation and Maintenance

Follows the ‘Cooling Tower selection’ course and provides an overview of standards, best practices and other legislation governing cooling towers which involve Legionella risk, trade waste processes and water treatment.

Topics covered include: Legislative requirements, principles for installation, pipework, risk, capacity testing, commissioning and testing, maintenance, water quality and water treatment.



Pumps - General Characteristics

Provides an introduction to the workings of a pump, how to identify different types of pumps and their materials and components and the calculations required prior to selection.

Topics include why pumps are used, types and classifications, pressure and head characteristics, basic pump laws and other pump characteristics.

Pumps - Selection and Application

Follows the ‘General characteristics’ course and covers calculating system requirements, matching a pump to the specified duty, looking at pump arrangements and configurations as well as an overview of testing and troubleshooting.

Topics include factors affecting selection, how to select a pump, performance curves, various applications, testing and trouble shooting.
