Study of a Two-Pipe Chilled Beam System for both Cooling and Heating of Office Buildings

In this study the energy saving potential of the new two-pipe active chilled beam system is investigated.

Active chilled beam systems are used to provide heating and cooling in order to achieve comfortable thermal indoor climate. For heating and cooling applications, an active chilled beam has two water circuits comprising four pipes that supply warm and cold water respectively to the beam coil according to the space demand. Lindab Comfort A/S has introduced an active chilled beam system which has just one water circuit (two pipes) that is used for both heating and cooling. The concept is based on high temperature cooling and low temperature heating. In this study the energy saving potential of the new two-pipe active chilled beam system is investigated.
