What is a Chilled Beam?
A chilled beam is a type of convection system designed to cool cubicles and the like. Often, they are integrated into the suspended ceiling system. Chilled water is piped to the beam and provides convective cooling. Pipes of water are passed through the beam and the circulated cold water will chill the air around the beam. The air becomes denser and falls to the floor. It is replaced by warmer air moving up from below, causing a constant passive air movement called convection, which cools the room.
The chilled beam is distinguishable from the chilled ceiling. They both uses water flowing through pipes, but in a chilled beam it is the thermal transfer from the pipes which cools the air. This makes chilled beams up to 85% more effective at convection than chilled ceilings.
Chilled beams are commonly seen in office facilities and common areas in office blocks, hospitals and other similar facilities and both pipe size and flow rates are normally in the lower end.
How is a Chilled Beam Application Optimized?
A chilled beam will - with proper balance on the water - reduce flow to design requirements and save energy. FlowCon recommends three different solutions to a chilled beam installation:
1. Chilled Beams with Pressure Independent Control (PICV)
The PICV will react to system pressure changes and regulate the flow of water to required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.
FlowCon recommends the following PICVs:
2. Chilled Beams with Temperature Control (TCV)
The TCV will react to system pressure changes and automatically provide the selected max. flow independent of pressure changes. In addition, the actuator will provide ON/OFF control, securing proper thermal performance always, even at partial loads.
FlowCon recommends the following TCV:
3. Chilled Beams with Automatic Balancing (ABV)
The automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to required max. flow helping the system to be accurately controlled even with pressure changes. This solution may be installed with the separate control valve.
FlowCon recommends the following ABVs:
