Pressure Enthalpy ... chilled beam system with site recovered energy Johnson Controls - Proprietary. The performance of a particular chilled beam will be determined by the coil-to-air heat transfer; the free area for room air flow; the temperature and flow rate of the coil water; and, in the case of an active unit, the quality, volume flow and induction capability of the primary air supply, and the resulting throw/diffusion of the air. It is made of convective coils that are placed in the ceiling of a thermal zone to provide sensible cooling and/or heating. Recessed Passive Chilled Beam. Beams should be mounted no more than 20 feet above the occupied level. What are Chilled Beams?

Since large buildings require large amounts of energy to keep cool, the idea of a chilled beam system is to use natural convection (warm air rises, cool air falls) and the superior energy capacity of water to make cooling much more economical. 0000005834 00000 n Chilled Beams originated in 1986 with the first passive chilled beam being installed in Stockholm, Sweden. This week's podcast is the question I was asked most at the ASHRAE show this week, "How do active chilled beams work?" The forced primary air can force the heated air down to the occupied space. 0000003851 00000 n Chilled Beam Systems are quieter than forced-air systems (fan coil units, water source heat pumps, etc.) It is made of convective coils that are placed in the ceiling of a thermal zone to provide sensible cooling and/or heating. The difference between passive and active beams revolves around the way airflow and fresh air are brought into the space. At the time of order, a number of items would have to be coordinated for the beams to be fabricated for successful installation. Active beams may be used for both cooling and heating applications.
