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.

This course provides a foundational look at the design and selection of large-diameter ceiling fans, focusing on their role in modern HVAC strategies. Participants will examine the relationship between airspeed and thermal comfort based on ASHRAE Standard 55, learn to optimize duct design by utilizing fans for secondary air distribution, and evaluate the "cooling effect" that allows for higher thermostat setpoints without sacrificing comfort. From comparing direct-drive versus gear-driven technologies to understanding the resiliency benefits of air circulation during system failures, this session equips professionals with the tools to design more sustainable, lower-cost building environments.

This course explores the concept of "microclimate mastery" using High-Volume, Low-Speed (HVLS) fans to create adaptive, personalized comfort zones within large-scale facilities. You will learn how to solve chronic airflow challenges such as stratification, architectural barriers, and variable occupancy shifts that traditional HVAC systems struggle to address. The session highlights strategies for integrating HVLS technology with Building Management Systems (BMS) to drive sustainability, improve indoor air quality, and achieve a rapid ROI through energy savings and enhanced employee productivity.

This course provides a technical overview of how fans are tested under AMCA 210/211 standards and why those results can differ from field performance. Participants will learn to identify common "performance killers," such as poor aspect ratio inlet boxes and abrupt discharge elbows. The session highlights the physics of airflow and offers practical solutions like turning vanes and no-loss rain stacks to reclaim lost static pressure. Instructor: James Conway PDH: 0 Read more

This module explores the fundamentals of modern air curtain design, focusing on the critical balance between performance, energy savings, and acoustic comfort. Learners will discover what separates a highly effective air curtain from one that is ultimately turned off by occupants due to loud noise or uncomfortable air blasts. The course examines the three primary barriers air curtains create and details how these systems protect valuable conditioned air to reduce wear on primary HVAC equipment.  Instructors: Sami Aslam, Ramin Namvar PDH: 0 Read more
