The fan power law defines the fundamental engineering relationship between four key indicators of fan performance: fan flow rate; fan static (or total) pressure, fan power, and fan static (or total) efficiency. In this self-guided course, you will work with the elements of the fan power law equation and explore how they interact. You will also practice calculating the compressibility factor and the fan electrical and mechanical power.

At a given rotational speed and fan pressure, centrifugal fans will develop a constant volume of airflow. Due to uncertainties in the final layout and construction of the ductwork, combined with the prospect of critical or changing process needs, many fans are selected to deliver more pressure and flow than what the industrial process or air-conditioning system actually requires. Some sort of control must then be employed to reduce the airflow to the desired level. In this self-guided course, you will explore common methods used for varying the flow capacity of the fan, such as speed control, outlet dampers, inlet dampers and inlet vane control. Your knowledge of these methods will allow you to accurately estimate and compare the power among the different methods. With this skill you can accurately predict the possible savings of changing to a more efficient method.

Psychrometrics is the study of the properties of mixtures of air and water vapor. A general knowledge of psychrometrics is very useful in fan application engineering, mainly because the performance of the fan is directly related to the density of the gas. Knowledge of psychrometric principles allows the fan application engineer to measure the amount of water vapor in the air, determine the density of the mixture, and thus accurately predict changes in fan performance. In this self-guided course, you will graphically explore psychrometric properties, such as dry bulb, wet-bulb, relative humidity, dew point, and humidity ratio as they are plotted on the psychrometric chart. Your knowledge of these properties will allow you to accurately calculate density and give you other skills useful in fan application engineering, such as the ability to predict whether condensation will occur in the system.

Developed by Air Movement and Control Association (AMCA) International, fan energy index (FEI) is the ratio of the electrical power of a reference fan to the electrical power of an actual fan, both calculated at a given airflow and pressure duty point, so that specifiers can make meaningful comparisons of fans. This training explores the engineering methods used to determine FEI ratings, plus an explanation of how to calculate the reference fan electrical power (FEPref), the actual fan electrical power (FEPact), and the fan energy index (FEI). Includes free copy of AMCA Standard 208 Calculation of the Fan Energy Index and AMCA Standard 207 Fan System Efficiency and Fan System Input Power, Calculation normally sold separately for $90 each - a $180 value. FSO310a Introduction to FEI is a mandatory prerequisite for this course. Includes pdf course notes that are handy for future reference, and make it easier for you to follow along, especially if English is not your first language. Includes FEI spreadsheet calculator for you to compare energy usage among 3 fans. You can leave the course and the system will save your progress for when you come back. Explore or re-visit topics in the sequence you desire. Learning activities, quiz questions and over 40 equations to solve keep you engaged in the topic.

Developed by Air Movement and Control Association (AMCA) International, fan energy index (FEI) is an efficiency metric designed in part to drive significant and quantifiable energy savings through use in codes, utility rebate programs, and regulations. This self-guided course examines FEI as it applies to stand-alone fans. It describes the concepts behind FEI, advantages of FEI compared with the fan-efficiency-grade (FEG) metric it is replacing, how to use FEI to estimate lifetime fan energy savings, and methods for applying FEI in building codes and efficiency programs. Includes free copy of AMCA Standard 208 Calculation of the Fan Energy Index normally sold separately for $90.
