A chilled beam is an air distribution device with an integral coil that may be installed within a space in the buildings in order to provide sensible cooling and heating.
Cooling only Passive Beam Applications
- No Fresh air supplied through beams -Libraries
- Beams are simply finned coils containing cold water – Shops
- Often used in conjunction with displacement – Atriums
- No control on air flow patterns in the room – Corridors
- Lower levels of occupant comfort
- Higher risk of draughts
- Not to be located directly over occupants
Active Chilled Beams
- Heating & Cooling
- 4 Pipe System
- Ducted Fresh Air

Energy Efficiency of Chilled Beam System
- Eliminates numerous small fans in fan-coils throughout building
- Increased inlet water temperature in cooling (14 OC or above)
- Improved chiller efficiency (Significantly higher COP)
- Easier to use free energy sources and heat pumps (Dry Coolers, Aquifer etc)
- Decreased inlet water temperature in heating (35…40 OC)
- Full, minimum fresh air system, typically:
- Small ducts
- Small AHU
- Lower duct pressure than in traditional induction units
