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.”

Learning Objectives

Upon completion of this course, participants will be able to:

• Interpret the properties of moist air using a psychrometric chart.
• Calculate energy content, heat- and mass-transfer rates, and required airflow rates for spaces.
• Determine the environmental control required to bring air into the comfort zone.
• Interpret air state points through different psychrometric processes and explain the cause of each directional movement on the chart.
• Distinguish among room sensible heat factor (RSHF), grand sensible heat factor (GSHF), and effective sensible heat factor (ESHF).
• Describe cooling and dehumidification systems for hot and humid climates.
• Size cooling coils and calculate the required airflow rate for air-handling units.
• Explain humidification systems for cold and dry climates.
• Describe the application of energy recovery and the economizer cycle to ventilation systems.
• Apply psychrometric analysis to environmental-control systems using practical calculations and examples.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 35 questions. PDH credits are not awarded until the course is completed and quiz is passed.
