HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this comprehensive episode of the HVAC podcast, Bryan hosts an in-depth discussion about dehumidification technologies with two industry experts: David Schurk, National Sales Manager for Innovative Air Technologies, and Nikki Krueger from Santa Fe Products. The conversation explores the fundamental differences between compression refrigeration dehumidification and solid desiccant systems, providing valuable insights for HVAC professionals dealing with moisture control challenges.

David Schurk brings 44 years of industry experience and serves as an ASHRAE Life Member and Distinguished Lecturer, teaching humidity control professional development courses. His expertise focuses on solid desiccant dehumidification systems for industrial and heavy commercial applications. Nikki represents Santa Fe Products, pioneers of whole-house ventilating dehumidification technology since the mid-1990s, and discusses the growing residential and light commercial market demands driven by tighter building construction and stricter energy efficiency requirements.

The discussion delves into the critical importance of understanding dewpoint versus relative humidity measurements, a fundamental concept that often confuses technicians in the field. The experts explain how the dew point remains consistent throughout a space while relative humidity can vary dramatically based on temperature differences between rooms, floors, and ceilings. This understanding is crucial for proper system design, troubleshooting, and customer education, especially as homeowners become increasingly aware of indoor air quality concerns.

The conversation also addresses the intersection of building science and dehumidification technology, emphasizing that proper moisture control requires both well-designed building envelopes and appropriate mechanical systems. From residential applications dealing with tighter construction and mechanical ventilation requirements to industrial processes like lithium battery manufacturing requiring extremely low humidity levels, the experts highlight how different technologies serve specific market segments while sometimes overlapping in commercial applications.
