Tony Mormino, alongside Joe Naccarello and Mark Murray, clarifies the differences between manufacturers and assemblers in this HVAC Quick Take. They discuss how vertical integration affects quality, reliability, and supply chain control, offering invaluable insights for industry professionals. This discussion is part of the broader "How To Master Custom Air Handlers" event.

Join us for an exclusive behind-the-scenes look at the practical application of advanced dehumidification technology driving the recovery efforts in Biltmore Village after Asheville's devastating flooding. This video explores how desiccant dehumidifiers and generators are not just equipment but crucial tools in drying out buildings, showcasing resilience and determination in the face of disaster.

With unique access to one of the hardest-hit areas, watch as Gary Peterson from CDI illustrates dehumidifying spaces to 5-10% relative humidity, essential for high-capacity moisture removal and preventing long-term damage within flood-affected structures. This unique walkthrough highlights the destruction caused by the flood and demonstrates the climatic recovery techniques employed to restore the community rapidly. 

Does hot gas reheat dehumidify the air? In this HVAC Quick Take, we unravel the truth behind hot gas reheat systems and their impact on air humidity. Discover how these systems work and why they only heat the air sensibly without affecting moisture content. This episode is part of the August 2023 HVAC MythBusters event, clarifying a widely misunderstood concept in HVAC design.

In this special episode of HVAC-TV, host Tony Mormino and special guests Mike Singer and Kevin Quillinan explore the critical factors involved in solving humidity challenges in building environments. From construction type and infiltration to occupant activity, they highlight the importance of a whole-building approach to achieving optimal indoor air quality.

The episode dives into the nuances of controlling temperature versus humidity and explains the role of sensible heat ratios (SHR) and psychrometric charts in system design. The discussion also covers effective strategies for managing part-load conditions and implementing solutions like reheat systems, modulating compressors, and advanced HVAC technologies.

Whether you’re designing systems for commercial buildings or troubleshooting existing spaces, this episode provides valuable insights for HVAC professionals.
