Cooling water temperature in chilled beam systems!

Cooling water temperature in chilled beam systems!

Chilled beam coils are “intended to remain dry, the chilled water supply temperature should be maintained at our above the room dew-point temperature. The primary air delivered to the beam is the sole source of room dehumidification.”  (Loudermilk & Alexander, 2012)

Due to higher cooling water temperatures there is no need for condensate drain pan, since the cooling process is not followed by dehumidification or condensation. (Ventura, 2013)

Because chilled beams are ceiling mounted and don’t use drain pans, the chilled water supply temperatures must be above the ambient dewpoint. (Cuniff, 2013)
