Different types of chilled beams

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

• 14°C water does not overcool air
• No fan –low air velocities
• Uniform Temperatures
• Small vertical temp gradient
• Well mixed airflow
• Easy installation
• Flexible layouts
• No noise
• No fan breakdowns
• No fan electrical consumption
• No fan maintenance
• No Filters
• No filter maintenance
• No Condensation
• No wet coil
• No condensate drains
• No condensate leaks

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
