FRB Chilled Beam

• FRB is a very compact passive chilled beam. The low build-in height, choice of two widths, plus the fact that water is used as an energy transfer medium, means that the system requires a minimum of space.
• The high performance of this chilled beam means that it maintains high cooling capacity even at low ∆T, which makes it possible to increase the temperature difference between the flow and return. This gives the product good operating properties and high output efficiency.
• FRB is specially designed for suspended installation. The softened form of the beam means that it blends into the room environments in a natural way.
• FRB particularly suitable for areas where heating and ventilation have already been installed, and require supplementary cooling.
• The system has no moving parts which will generate no noise and no maintenance is required.
• Water connections and valves are easily covered by a neat connection cover. The cover is mounted after the beam is hanged and connected.
• Cooling only function

The FRB passive chilled beam is designed to be exposed in the space.  The casing is finished and can be supplied in a range of standard colors. The FRB is well-suited for use in all types of rooms with waterborne climate cooling;

• Offices (Cellular and open)
• Hotels
• Classrooms
• Conference rooms
• Computer rooms
• Restaurants
• Banks
• Shops

The FRB is a passive chilled beam so there are no air connections. Passive chilled beams can only be used for cooling. If the beams are used for heating, the warm air will build up on the ceiling and there would be no air movement within the space. The water connections are 2 pipe only with 1/2 inch push on NPT fittings. The beam is suspended, pendant style below the ceiling. A spacing of 4 inches (100mm) is recommended to optimize capacity.

FRB Passive chilled beam performance can be calculated using Swegon’s Proselect Software. The Swegon application team can assist with your chilled beam applications ranging from selections to full system design review with our DesignEdge service.

Cooling

The cooling capacities have been measured in conformance with EN 1516 Standard. Detailed performance data are available in ProSelect with the following:

• The length of the climate beam (inches)
• The primary airflow (CFM)
• The noise level for an open damper, with ADC
• Nozzle pressure (inWG)
• Airborne cooling capacity (BTUH)
• Waterborne cooling Capacity (BTUH)

The total sensible cooling capacity is the sum of the airborne and waterborne cooling capacities.

Recommended limit values ensures that any air in the system can be expelled at the minimum water flow rate per circuit.

FRB is designed for suspended installation.  The distance below the ceiling should be 4 inches (100 mm) for best capacity.  As  an option, the FRB can be supplied without the casing  and fitted in ceiling plenum if there is open grid in the suspended ceiling.
