    Description

    Fan and System Curves

    Fan and system curves are graphical tools used to analyze performance and understand a fan’s response in a particular system. This webinar defines the common language used to explain and discuss all aspects of fan performance. Also, it introduces the U.S. Department of Energy's MEASUR software tool and explains how it can be used to analyze fan systems.

    70-minute webinar

    Pressure Considerations in Fan Systems This session provides valuable insights into standard air calculations, the role of pressure in fan systems, identification of pressure sources and losses, and techniques for calculating velocity pressure. Whether you are involved in fan manufacturing, fan-system design, operation, or maintenance, this webinar will enhance your understanding of pressure dynamics and help you optimize the performance and efficiency of your fan systems.

    30-minute webinar
    Fan Affinity Laws Simplified The performance of a fan is defined by the flow, pressure, and power draw of the fan. The fan affinity laws (also called the fan laws, for short) are a set of interrelated equations that predict the performance of a fan under varying designs and conditions. In this self-guided course, you will apply a simplified set of affinity laws to predict fan-performance changes attributed to changes in rotational speed and changes in density compared with catalog conditions and predict changes in fan performance attributed to speed and density changes.

    Allow at least 45 minutes for completing this course.

    Motors

    The motor is a key part of any fan system. This short self-guided course examines critical characteristics of NEMA motors to give you a foundation of knowledge for applying motors in fan, pump, and blower systems.

    Allow at least 45 minutes for completing this course.

    Centrifugal- and Axial-Fan Characteristics

    Different styles and types of fans are designed to serve different purposes and different end uses. This webinar explains the major types of fans and common applications for which they are best suited.

    60-minute webinar

    Losses in Elbows and Ducts Understanding the dynamics of airflow is crucial for the design of efficient duct systems. This session will explore velocity-pressure calculation, loss coefficients, equivalent duct diameter, and turbulent flow. Learn practical techniques for calculating duct pressure loss and identifying efficient elbow design based on radius-to-diameter ratio and the impact of multiple elbows on pressure loss. Join us to enhance your understanding and optimize duct-system performance.

    30-minute webinar
    Fan-System Controls

    At a given rotational speed and fan pressure, centrifugal fans develop a constant volume of airflow. Because of uncertainties in the final layout and construction of ductwork, combined with the prospect of critical or changing process needs, many fans are selected to deliver more pressure and flow than what an industrial process or air-conditioning system 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 to vary the flow capacity of a 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.

    Allow at least two hours for completing this course.
    Pressure Losses and Duct Systems

    Losses in ductwork are only one aspect of the pressure a fan must overcome to perform successfully. In this webinar, the instructors will estimate losses in ductwork, introduce special considerations for estimating losses across filters and cooling coils, and demonstrate the ASHRAE tool for estimating losses in duct fittings. Losses for an entire system, including acceleration losses and hood losses, will be introduced.

    60-minute webinar
    System Effect in Fan Systems

    Sometimes, good fans end up being installed poorly, resulting in deficient fan performance. In this webinar, the instructors will describe system effect, explore situations that can cause system effect, and look at some analytical tools to quantify the impact on fan performance.

    90-minute webinar

    Power and Compressibility of Fans

    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 also will practice calculating compressibility factor and fan electrical and mechanical power.

    Allow at least 75 minutes for completing this course.

    Fan Affinity Laws Advanced

    Building off the simplified affinity-laws course, this module explores the subtleties of analyzing the affinity laws with high-pressure (over 3000 Pa or 12 in. w.g.) systems. In high-pressure systems, compressibility factor must be calculated. Usually, when rotational speed or density changes, compressibility factor also changes. In this course, changes to compressibility factor are considered and a method from ANSI/AMCA Standard 210/ASHRAE Standard 51, Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating, for calculating compressibility factor is presented.

    Allow at least 50 minutes for completing this course.

    Certified Ratings and Fan Selection

    In this session, the instructors discuss tips for selecting proper fan size, giving examples from manufacturers' selection programs. To achieve desired airflow and pressure rating without exceeding a power specification or allowable noise, the session goes over the importance of specifying an AMCA-rated fan and what it means when a fan is AMCA-rated.
