Overview
Maintaining thermal comfort for building occupants is one of the most important goals of heating, ventilation and air conditioning (HVAC) design engineers. Psychrometrics is used to help select the proper air conditioning equipment and determine the environmental conditions that affect human thermal comfort.
Psychrometrics is a study of moist air. Air conditioning engineers use the psychometric chart to predict changes in the environment when the amount of heat and/or water in the air changes. A psychrometric chart provides a convenient way to look at the air conditioning processes, and it will answer why heated air can hold more moisture, and conversely, how allowing moist air to cool will result in condensation.
Once you understand the basic concepts, you will also understand how to mechanically manipulate the environment to achieve the desired space conditions.
This course introduces psychrometric charts and describes the interactions of air, moisture, and temperature for achieving desired space conditions. The course will benefit HVAC design engineers, energy engineers, HSE professionals, and facility operational and maintenance engineers.
