Cost versus energy in traditional chilled beams systems!

Most cost effective use of chilled beam system design decouples latent cooling from the room unit, providing latent cooling centrally at the AHU coil. (Rumsey & Weale, 2006)

  • 25% savings from centralized latent cooling
  • 46% savings from total cooling energy generation.
  • Greater chiller efficiency
  • More available hours of free-cooling, water-side economizer.  (Rumsey, Bulger, Wenisch, & Disney, 2009)
