The purpose of this presentation is to educate engineers, system designers, and fan application specialists on the calculations required to determine air or gas density. This webinar was originally broadcast on July 14, 2020. Speaker: Bill Howarth  Length: 60 minutes  PDH credits: 1 Read more

This session explores the replacement of bulky ductwork in parking structures with high-velocity jet fan systems. Participants will learn how to mitigate CO and NO2 levels using thrust-based induction, which reclaims overhead space and reduces construction costs. The course also quantifies the significant energy savings achieved through Demand Control Ventilation (DCV) and the use of CFD modeling to ensure code compliance and air quality.

The purpose of this presentation is to review the need for engineered controls to address environmental, "outdoor" sound propagation, as it affects neighboring communities. This webinar was originally broadcast on September 30, 2020. Speaker: John Sofra  Length: 60 minutes  PDH: 1 Read more

This webinar was originally broadcast on September 16, 2020. The purpose of this presentation is to inform industry professionals about the factors involved in designing a laboratory exhaust system. The presentation will outline the selection of the exhaust fans enhancing the highest potential turndown and the different laboratory control options that will affect the energy consumption of the laboratory.

This module provides a comprehensive overview of fan fundamentals, focusing on the critical relationship between fan speed, airflow, static pressure, and horsepower consumption. Learners will explore foundational fan laws, including how static pressure varies as a function of the change in speed squared, and how brake horsepower varies as a function of speed cubed. The course also covers the aerodynamic and physical considerations necessary for proper fan selection ensuring systems operate effectively in the field. Instructor: James Mathis PDH: 0 Read more

After a performance test is completed, the data is used to calculate the fan parameters such as flow, fan static pressure, fan static efficiency fan total pressure, and so on. This self-guided course uses two completely separate avenues to teach the calculation method. In the first, you learn the calculations and their order by navigating your way through the problem, which is presented as a learning puzzle. We have fondly named it "the labyrinth" because as you navigate the challenge, you are exploring the relationships between the variables. In the second approach you approach the calculations in linear order and learn how to program them into a pre-formatted spreadsheet that you can use on future projects. The second approach is optional. 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 IP - SI spreadsheet calculator for unit conversion. 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 and quiz questions keep you engaged in the topics. SI units only. Allow at least 2 or 4 hours in your schedule for completing this course, depending on which parts you choose to do. Instructor: Ron Wroblewski  Course length: 2 hours  PDH credits: 2   Read more
