SVALBARD-F-VAV 

CHILLED BEAM WITH INTEGRATED VAV FUNCTION FOR EXPOSED INSTALLATION

  • Exposed (free-hanging) installation
  • Length from 1200 to 2400 mm
  • Pressure-independent VAV solution integrated
  • Optional bus protocol for VAV control

General information

Application
Svalbard-F VAV is used for demand-controlled ventilation as well as hydronic cooling and heating of offices, meeting rooms, and educational facilities. The unit is specifically developed to provide high cooling and heating capacity without causing draught in the occupied zone. Svalbard-F VAV is designed for exposed installation directly to the ceiling or slab.


Functional description
Svalbard-F VAV features an integrated, pressure-independent VAV damper at the inlet that regulates the primary airflow to the desired setpoint. Supply air is introduced into the room via fixed nozzles. The primary air flowing through the nozzles induces (draws along) room air through the coil, where it is either cooled or heated before being supplied to the room together with the supply air. The damper solution ensures a low sound level even when throttling high pressures. Svalbard-F VAV can be supplied with several different bus
communication options for connection to BMS systems. The control range of Svalbard-F VAV is shown in Table 2.
Measurement deviation by range:
10–20% of nominal: ±25%
20–40% of nominal: <±10%
40–100% of nominal: <±4%
In T-duct situations, a straight duct length of at least 5 x ØD is recommended to maintain the same measurement accuracy.


Design
Svalbard-F VAV is designed as a complete measurement and control unit for demand-based airflow control.
• VAV control: Integrated damper solution at the beam inlet, corresponding to the functionality of other TROX products.
• Nozzles: Supplied with fixed nozzle configuration. The nozzles are factory preset but can be manually adjusted on site if required.
• Motor options: Supplied with external rotary actuator from Belimo or Siemens for easy access via the ceiling. Regulator specifications are shown in Table 1. Complete technical documentation can be downloaded from www.belimo.eu and www.siemens.com.
• Water side: Coils are supplied as standard cooling coil (SKB), high-capacity coil (HKB), or combined heating and cooling coil (VKB). Connection via Ø15 mm copper pipes.
• Air side: Ø125 mm connection with integrated measuring cross for differential pressure measurement.
• Flexibility: The front panel is hinged for inspection, and the air distribution pattern can be manually adjusted with Jet Split vanes.


Material and surfaces
Svalbard-F VAV is manufactured in galvanized steel and supplied as standard painted white RAL 9003, gloss level 30. The coil consists of copper tubes with aluminum fins. The measuring cross in the inlet is made of aluminum, while hoses and nipples are made of plastic.


Size
For accurate calculation of cooling and heating capacities, sound power level, and pressure drop, the AURASIM simulation program is used


Commissioning
Svalbard-F VAV is delivered factory preset according to the order. If nozzle opening adjustment is required on site, a locking screw is loosened so that the nozzle slide can be manually adjusted. For damper motor commissioning, service tools such as Belimo ZTH-VAV or Siemens AST20 are used.


Maintenance
Full access to the coil and control unit is achieved by swinging down the bottom panel of the beam. Maintenance is normally limited to vacuum cleaning of the coil or cleaning with a damp cloth as required.
