The main purpose of heating, ventilation, and air conditioning (HVAC) systems is to maintain a comfortable environment within a building. This is achieved by supplying air at an appropriate temperature, humidity, and airflow rate.

In the design and analysis of HVAC systems, the fundamental requirement is to first calculate the total heating and cooling loads incident on the building and then establish the most efficient process to bring the air conditions to the comfort zone with the aid of psychometric analysis. A psychrometric chart is an industry-standard tool to visualize the air conditioning processes and to select the most appropriate air conditioning equipment for the job.

In this course, you will learn how to apply several psychrometrics processes to design practical heating and air conditioning systems. This course provides an intensive understanding of the very essential psychrometric principles and includes a lot of practical calculations and examples to give you a thorough grounding in this area.

If you are responsible for the design or maintenance of any aspect of air-conditioning in buildings, a clear and comfortable understanding of the chart will make your job easier. The course will benefit HVAC design engineers, energy engineers, HSE professionals and facility managers, O&M engineers, architects working with contractors, and anyone interested in learning HVAC and Refrigeration Systems.

Prerequisite: Before studying this course module, it is expected that you have the basic fundamental knowledge of air properties, psychrometric charts, and air conditioning processes. For beginners and novice engineers, it is strongly recommended to first undertake Level 1 course “Application of Psychrometrics to Heating and Cooling.”
