Control and windows in chilled beam systems!

Control and windows in chilled beam systems!

Areas with operable windows have dew-point monitors to ensure that HVAC system operational parameters are adjusted as necessary to avoid condensation on the chilled beams.  (Guttman & Tiffany, 2013)

Rooms with operable windows have been shown to lower the dew point and dry bulb temperature quickly after closing the window. Research into hotel room recovery times has shown that after an operable window is closed the supply air alone decreases the dewpoint to a level permitting safe operation of the cooling coil in approximately 20 minutes.  (Johnsson, 2010)
