ADRIATIC VF Chilled Beam

The ADRIATIC VF is a closed, active climate beam with two-way air discharge. Cooling and ventilation or cooling, heating and ventilation. The units do not contain a fan of its own but is driven by the pressure and flow generated by a centrally located air handing unit, which means low sound level and excellent comfort in the room. The ADRIATIC models are designed for dry systems, i.e. without condensation and therefore does not require any condensate drainage system or any filter. The minimum number of moving parts and lack of filter guarantees very little need for maintenance.

The ADRIATIC VF chilled beams operate according to the induction principle. A centrally located air handling unit distributes primary air via the duct system into the plenum of the unit and creates excess pressure. The plenum is equipped with a number of sliding strips that in turn contain a row of nozzles of various sizes. The excess pressure in the plenum forces the primary air through the nozzles at relatively high velocity. When the primary air is distributed at high velocity through the nozzles, negative pressure is created in the space above the built-in heat exchanger (coil). The negative pressure draws (induces) the room air up through the heat exchanger where the air is treated as required.

• The ADRIATIC VF has an attractive design and extremely low installation height that fits well in all types of room décor.
• Since the ADRIATIC VF is a closed climate beam with integrated recirculating air opening in the face plate, it can be mounted directly against the ceiling without affecting circulation air slots.
• The ADRIATIC VF combines the superior air discharge properties of ceiling units with the stringent design requirements of suspended climate beams. The discharge of air along the ceiling provides the optimal Coanda effect that is always the objective when it is desirable to maintain low air velocities in the occupied zone.
• The connection components, valves and dampers are concealed in a simple manner by an attractive connection casing. The casing installed after the climate beam has been suspended and connected.
• Swegon’s ADC air diffusers, which are standard, provide for the adjustment of the air throw performance of the climate beam.
• Integrated VariFlow airflow distribution for simple volume adjustment on-site. The airflow can be varied to suit the application by means of nozzle strips. The fixed nozzles guarantee that the airflow will be correct and all-in-all offers a flexible and simple solution.

To achieve the best thermal comfort and account for future changes in the space (repurposing) ADRIATIC VF Chilled beams include Flexible nozzle configuration by means of VariFlow and Anti Draught Control (ADC).

Each side of the nozzle strips can also be configured for asymmetrical airflows. The number of nozzle strips for a certain length of beam is always the same.

The goal of a well-designed and operated chilled beam system is to obtain even temperature distribution throughout the space and avoid drafting (too fast air movement). To achieve this, The Swegon ADRIATIC VF climate chilled beams contain ADC as a standard. ADC stands for Anti Draught Control, which enables the diffusion pattern of the distributed air to be set up to avoid the risk of draft.

A ADC consists of a number of sections with adjustable fins arranged in the outlet of the beam with a simple grip of the hand. The fins are adjustable from a straight setting to 40° air deflection to the right or left in increments of 10°. In this way, the fins can be set to an appropriate angle to direct the discharge air and create the desired air distribution pattern. The static pressure is not affected by ADC. The sound level increases slightly when the air deflectors are set for “V-shape”. For more information, see the Swegon Proselect program.

The standard setting for ADC is straight but the unit can be supplied factory-preset to a V-shape distribution pattern if desired.

The ADRIATIC VF with ADC offers many benefits:

• Shorter center to center distance between  climate beams when higher capacity is required
• Simple correction of the direction of air discharge
• Easy to adjust the comfort setting on site
• Great flexibility for future conversion

The ADRIATIC climate beam comes standard with the 5-inch diameter air and water connections stubbed out horizontally at one end.  Both 2 pipe and 4 pipe beams are available.

THE ADRIATIC VF can also come with an extended finished cabinet to cover the air and water connects turned up vertically into the ceiling providing a clean look with air-water connections hidden from view. Piping and elbows can be supplied by Swegon or field supplied.

Swegon’s T-KA connection casing can be mounted in the extended section of the ADRIATIC VF beam and beyond to a wall designed to conceal horizontal pipe and duct connections. The T-KA has the same finish as the climate beam providing a clean installation.

ADRIATIC VF 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 DesignEdge.

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

• 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 cooling capacity (sensible) is the sum of the airborne and waterborne cooling capacities.

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

The heating function is intended for use only as a supplement if surplus heat is available; however, during shorter periods (like in the evening and at night), a certain amount of surplus heat will be needed. The supply air fan must be in operation for the additional heat to reach the room. The supply air is used for mixing the warm air with chilled primary air, which is why the temperature distribution in the room is completely dependent on the ratio between supply air and the capacity taken from the chilled beam. The heat is conducted along the ceiling. A temperature gradient of 9.7 °F is normally obtained between floor and ceiling.
