• (On Demand) Duct Fundamentals – The Magic of Duct

    On Demand Webinar

    Provided by CaptiveAir 1 CEU available Speaker: Bill Griffin German Tabor Course Description: No matter how perfect your HVAC unit conditions the air, it can all go awry if the delivery method is not well thought out. The first step is understanding exactly how air behaves in a duct. From Bernoulli’s Theorem to friction, dynamic losses, system effect, we’ll visualize every step of the way to make the concepts intuitive and fun. Prerequisite Knowledge:  None. Learning Objective 1:  Understanding Total, Static, and Dynamic Pressures within the context of ductwork. Learning Objective 2:  Understanding friction losses and the factors at play in a duct. Learning Objective 3:  Understanding dynamic losses and pressure loss coefficients within duct fittings. Learning Objective 4:  Understanding system effect and its impact on duct losses To access, click this link - https://www.youtube.com/watch?v=AXJ79HH3wi0

  • (On Demand) Parallel Ducts – A Balancing Act

    On Demand Webinar

    Provided by CaptiveAire 1 CEU available Speakers: Bill Griffin, German Tabor Kyle Thompson Course Description: Nature does what it wants, which means air in parallel duct branches doesn’t always behave how me might expect. In this video we’ll explain how we can predict and model complex airflows using simple calculations, and how software does it in an efficient, intuitive way. Prerequisite Knowledge: Duct Fundamentals Learning Objective 1: Understand loss coefficients for diverging tees. Learning Objective 2: Understand how to balance a duct system using the Equal Friction method. Learning Objective 3: Understand how to balance a duct system using the Static Regain method. Learning Objective 4: Understand how software may be used as an alternative to hand calculations, including general advantages and limitations.

  • (On-Demand) Ductwork – The Most Overlooked Aspect of HVAC

    On Demand Webinar

    Provided by CaptiveAire 1 CEU provided Speakers: Bill Griffin, German Tabor, Kyle Thompson, Nick Perry Course Description: Nobody cares about ductwork. Should you? Absolutely.  We’ll show you why as we explain proper air diffusion, leakage, condensation, and the impact ductwork has on equipment selection and performance. If you’re still thinking of airflow in terms of 400 CFM per ton and traditional diffusers, this is the video for you. Prerequisite Knowledge: None Learning Objective 1: Understand the purpose of air diffusers, how air moves in a space, as well as the distinction between traditional and high induction systems. Learning Objective 2: Understand the importance of thorough duct design in a building and the negative impact of field changes and leaks in a duct system. Learning Objective 3: Understand how duct design can affect airflow requirements and equipment selection. Learning Objective 4: Understand duct condensation and how smart HVAC controls can prevent it. Video link: https://youtu.be/7uQtCyIHIJ4

  • (On Demand) Fundamentals of Refrigeration

    On Demand Webinar

    Presented by Utility Refrigerator Fundamentals of Refrigeration (1.0 CEU) - A discussion of the basics of refrigeration, applicable to all refrigeration systems ranging from a small dorm refrigerator up to a refrigerated warehouse. Participants will have a thorough understanding of what makes refrigeration works after attending this session. We also discuss newer hydrocarbon refrigeration systems, such as those operating on R-290 and R-600a. Contact Marcella Zavala for On Demand access
