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.

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  Upon completion, you will earn: 2 Professional Development Hour (PDH) with AMCA completion certificate The AMCA Air Systems Foundations digital badge (issued via Credly) Note: This micro-credential serves as your official entry point and foundational baseline for AMCA’s stackable credentialing pathways.

In many fan systems, the amount of electrical energy used to drive the motor is a small fraction of the thermal energy carried by the air or gas. When this thermal energy is wasted, or dumped to atmosphere, it can represent a huge opportunity for energy savings through heat recovery. In new commercial air conditioning applications where there is a high demand for outdoor air, recovering the "cool" energy in the air that is spilled is often immediately cost effective, without any payback period. Industrial thermal processes such as boilers, foundry dust exhaust, and steel mill ovens, (among others) are often great candidates for heat recovery. In this course you will be introduced to 5 different strategies for thermal energy recovery, including the use of: heat wheel, air-to-air, air-to-water, water-to-air, and glycol run-around heat recovery systems. The course also includes a method for estimating the potential energy savings, so you can see if the project has enough value to proceed with the design and implementation.
