Leveraging Displacement Ventilation & Displacement Chilled Beams
There is a growing demand within North American school districts for their schools’ buildings to perform more efficiently within shrinking budgets, while simultaneously accommodating the introduction of new technologies into the classroom and operating for 50-70 years in an ever-changing environment.

Low temperature overhead air distribution (also called cold air distribution) supplies cooling air to the occupied space with an entering air temperature typically between 40°F and 50°F [4.4 and 10°C]. This contrasts to the “typical or conventional” overhead air distribution cooling supply air temperature between 50°F and 59°F [10 and 15°C].

Water condensation is easily the most common concern when discussing chilled beams and cooling panels. This concern comes from the personal experience many have had of seeing water droplets form on the surface of piping such as a water coil.

ACTIVE CHILLED BEAMS
In a chilled beam, the term “induction” is used to describe the process of injecting primary air under pressure through a nozzle, which in turn entrains return or plenum air at the discharge of the nozzle.
