This course is designed for engineers and technicians from a wide range of abilities and backgrounds. It will provide an excellent introduction to the fundamentals of heating, ventilation, and air-conditioning. It begins with a review of psychrometric charts and then examines the factors that influence design choices, indoor air quality, load calculations, and heating, ventilation and air-conditioning systems.
The course is composed of 12 modules, covering topics such as understanding and applying the psychometric chart, designing for good air quality, performing basic load calculations, and initiating an effective inspection and maintenance program.
