How The System Works
A passive chilled beam system works by passing chilled water through a casing suspended from the ceiling. As warm air naturally rises, it is then cooled by the beam, and begins to naturally lower the cool air back toward the floor. This system cools the air by convection, and thus eliminates the need for a fan. However, in an active system, an air supply pushes the room’s air toward the beam, cooling it more efficiently. The active type of system can also use a two pipe team to provide cool water cooling in warm months and hot water heating in cool months. However, this system has less heating capacity than other options and may often need to be supplemented with another option such as baseboard heating. Due to US building codes, each system must provide an outside air source to ventilate the space, and also provide air that is below the dew point of the chilled beam’s surface temperature to prevent excessive condensation and thus dripping of water into the cooling space.
Common Disadvantages To Consider
An active chilled beam system can often have a higher installation cost because the beams have a lower cooling capacity than other options. Items used to offset the cost of installation, such as pumps and fans, increase energy use, and thus overall cost. The surrounding air may often need to be dehumidified to prevent the condensation forming on the coils as water runs through the beams. A natural ventilation source, such as an open window, may be used, but there can be less control over the amount of condensation possibly formed. Another disadvantage is the possibility of water leaks occurring throughout the pipe system.
