Courtesy: Swegon 47 Active and Passive Beam Application Design Guide Figure 10-7 illustrates the use of a heat exchanger and separate, closed water loop. The primary water flow in the heat exchanger is modulated to maintain the beam chilled-water supply temperature; this is used when there are several uses of the primary chilled-water circuit. Beam chilled-water temperature control is a closed-loop control system in which the supply water temperature is controlled via adjustment of the water flow through a two- or three-way control valve or heat exchanger installed on the suction side of the pump.

Condensation detected on the supply pipework does not mean that the chilled beam will start to condensate and then drip. Condensation can remain on the supply pipe for a very long time, and still no condensation will be present of the chilled beam. The protection provided by these devices must be weighed against the probability that more thermal complaint calls may arise when and if the chilled-water supply is discontinued during periods where an inconsequential amount of moisture is detected by the contact switch.
