All About Dehumidification

Indoor Air Quality specialist Nikki Krueger explains the importance of dehumidification and best practices for optimal conditions

In this episode of the BS* + Beer Show, Nikki Krueger explains why dehumidification is so critical—particularly during the shoulder seasons, “when dehumidifiers shine.” Her superb presentation includes high dew point (DP), relative humidity (RH), and temperature (T) maps of the country and what they mean for dehumidification best practices. (Nikki recommends DPCalc for calculating combinations of T, RH, and DP.) We learn why HVAC equipment is commonly oversized—because it is designed for peak conditions, which occur 1% of the time—and how partial loads (and 55% dew point) should be used for most HVAC designs. Nikki explains why it is critical to know the sensible heat factor of equipment for right-sizing, the value of dedicated dehumidification, the meaning behind “A.C. is King, Dehumidifier is Queen,” and why dehumidifiers in encapsulated crawlspaces are a good strategy—among many other valuable building science lessons. She also references Joe Lstiburek’s “Built Wrong from the Start.” So, get ready to take some notes.

Enjoy the show!

    I'm sorry I wasn't able to be on screen but glad it was a good show! Our next show is November 2 with Gary Klein talking about hot water distribution. I doubt anyone in history has thought more about how to get hot water where it needs to be as quickly and efficiently as possible.
