Solution
A chilled beam is a type of convection HVAC system designed to heat or cool large buildings.
Pipes of water are passed through a "beam" (a heat exchanger) either integrated into standard
suspended ceiling systems or suspended a short distance from the ceiling of a room. As the beam
chills the air around it, the air becomes denser and falls to the floor. It is replaced by warmer air
moving up from below, causing a constant flow of convection and cooling the room. Heating
works in much the same fashion, similar to asteam radiator. There are two types of chilled
beams. Some passive types rely solely on convection whilst there is a "Radiant"/convective
passive type which cools through a combination of radiant exchange (40%) and convection
(60%) which can provide higher thermal comfort levels, while the active type (also called an
"induction diffuser")[8] uses the momentum of ventilation air entering at relatively high
velocity to "induce" circulation of room air through the unit (thus increasing its heating and
cooling capacity).
The chilled beam is distinguishable from the chilled ceiling.The chilled ceiling uses water
flowing through pipes like a chilled beam does; however, the pipes in a chilled ceiling lie behind
metal ceiling plates, and the heated or cooled plates are the cause of convection and not the pipe
unit itself Chilled beams are about 85 percent more effective at convection than chilled ceilings.
The chilled ceiling must cover a relatively large ceiling area because it provides heating and
cooling mainly by radiant, rather than convective, heat transfe
