Induction & Chilled Beams

An Induction or Chilled Beam takes a source of primary air at an inlet static pressure ranging from 0.2″ to 0.8” of WC. It distributes this air through a bank of specially designed aerodynamic nozzles and discharges the air at a high velocity into a mixing chamber. This creates a differential pressure which enables a draw of room air across a coil. This imparts either cooling or heating to the induced air as it passes over the coil. The primary air and induced air are mixed and discharged through a grille in a coanda effect air distribution at the ceiling. This air circulates throughout the room and is gently drawn back up through the return section of the Induction or Chilled Beam grille.  The total room air circulation is created solely by the induction principle within the terminal.  This eliminates the need for an electric motor and its power source.  As a result, the Induction or Chilled Beam is a very quiet and efficient way to provide comfort in a space.

Chilled Beams Are Sensible Only Terminal Units

Chilled Beams are sensible only terminal devicves and do not have the ability to handle latent conditioning in the occupied space.  In Chilled Beam designs the latent load in the space must be handled by the primary air source.  Chilled beam systems offer energy savings for little additional costs over conventional systems. Since traditional (sensible only) chilled beams utilize water with temperatures that are above the dew point of the space, maximizing chiller efficiency becomes possible. Using dedicated chillers that produce water temperatures typically from 56 F to 60 F can increase efficiency dramatically in a building. These elevated water temperatures can also lead to other benefits, such as the option to use water-side economizer or free cooling.  In some moderate climates, electric chillers can even be eliminated and chilled water can be produced directly from a cooling tower with a storage tank.   For heating, the use of condensing boilers that produce lower water temperatures (i.e. 100 F to 120 F) can be used to efficiently and effectively meet the heating load in the space.

Induction Beams Are Sensible & Latent Terminal Units

Unlike a conventional Chilled Beam, Induction Beams have drain pans as a standard.  Induction Beams are most often referred to as a fan coil unit without the fan or motor.  The drain pan adds a number of advantages that include; reduced system first cost, less mechanical equipment, simplified controls, increased design flexibility, and greater liability control.  Induction Beams provide a lower first cost option when compared to a traditional sensible only chilled beam system.  Induction Beams can use much colder water temperatures thus providing much higher BTU/CFM ratio’s.  This usually equates to fewer beams being required to meet the room loads.  Less beams can also mean less primary air is required.  Induction Beams enhance the savings and effectiveness of primary air systems. When using Induction Beams, the primary air system, which includes the air handler and the supply and exhaust duct work, can be sized to handle only the required ventilation air. This reduces the size of the equipment and ductwork making it easier to fit into a building space. This also reduces the energy required to supply the ventilation to the building.  Induction beams do not require the elaborate controls associated with sensible only Chilled Beam systems to control condensation before it occurs.  Also, Induction Beams do not require an additional piping loop with heat exchangers, mixing valves, booster pumps or condensate sensors to maintain the water temperature above the dew point, which is required in traditional sensible only Chilled Beam systems.
