Chilled Beams

Chilled beams are convective cooling systems with (active) or without (passive) forced ventilation, which are normally mounted on the ceiling. Chilled beams with forced ventilation are special, as only the secondary air flows via the heat exchanger, which is induced by the primary air flow. Passive chilled beams are tested according to EN 14518, and active chilled beams according to EN 15116. The measurement methods described in the European standard can be carried out both in an adiabatic test room (with internal cooling load) and in a test room where the cooling load is inserted via the walls. The tests according to the European standards comprise the determination of the standard cooling capacity and the characteristic equation of the cooling capacity for at least two different cooling water flows. Active chilled beams require measurements with nominal primary air flow rate as well as with a 20% lower and 20% higher air flow rate.

EUROVENT set up a European certification system for chilled beams. The test concept is based on the European standards mentioned above. WSPLab is the only test laboratory that carries out chilled beam tests for EUROVENT.
