Induction or Chilled Beam systems are HVAC systems. They take primary air at a static inlet pressure ranging between 0.2″ to 0.8” of WC.
The air is distributed through specially designed aerodynamic vents. They discharge the air into a mixing chamber. The differential pressure thus induces movement of air across the coil, thus heating or cooling the induced air.
The primary and the induced air are mixed and discharged through a grille on the ceiling. After circulation throughout the room, the air is drawn back through the return section of the Induction or Active Chilled Beam system.
As the total air circulation is a result of the induction principle within the terminal leading towards the elimination of the electric motor and its power source. This results in a quiet and effective air system.
Chilled Beam System
Active Chilled Beam is a sensible terminal device that cannot handle latent conditioning in the occupied area. The latent heat in the area is managed by the primary air source. It utilizes water above the dew point temperature of the space, thus helping to increase the chiller efficiency.
Dedicated chillers producing water temperatures in the range of 54 F to 60 F can increase the efficiency of the system in any facility. These water temperatures can be used for other options, such as using a water-side economizer for free cooling.
Similarly, for heating, the use of condensing boilers that produce lower water temperatures can be used to efficiently and effectively meet the heating load in any facility.
Benefits
- The height can be reduced to maximize space because active chilled beam don’t need much room for equipment or ducts
- As per chilled beam manufacturers, the chilled beam has the potential for great thermal comfort as these systems create a better air-distribution channel
- Lower fan use helps to minimize the usage of energy
Induction Chilled Beam System
The standard design of Induction Beams has drain pans which are not present in the Chilled Beams. The drain pan helps to reduce system first cost, reduce mechanical equipment, easy controls, design flexibility, and greater liability control. Induction Beams are referred to as a fan coil unit without the fan or motor.
They provide a high BTU/CFM ratio since they can use much colder water. This leads to fewer beams per room and also less primary air usage.
They do not need any additional piping loop with heat exchangers, valves, pumps or
condensation sensors to maintain the water temperature, unlike the traditional Chilled Beam systems.
Induction Chilled Beam does 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.

Benefits
- Cooling operates when needed and doesn’t require a safety switch to turn off the chilled water, unlike a conventional chilled beam
- A building can have multiple water loops with different water temperatures to manage specific requirements of each zone of any facility.
Chilled beam systems are perfect for regulating the temperature of the space they are installed in. By understanding the design and benefits of both chilled and induction chilled beam systems, you will be better able to make the decision about which one to install. While induction beams can work well for a lot of space, chilled beams are highly preferred by large areas like laboratories, hospitals, and others that need to maintain the perfect temperature for their operations.
