Description
General
• OptimAir M-L is a two-way induction type active chilled beam, designed for integration in false ceilings.
• OptimAir is primarily designed for
supply air, cooling and/or heating in buildings, where a comfortable indoor climate with individual room control is required.
• The unit is available with two plenum box options for either medium (M) or large (L) airflow requirements.
• The unit also offers two coil (heat exchanger) options to best suit cooling and/or heating
demands of the occupancy zone.
• The unit is designed to fit standard 600 mm suspended ceiling frameworks, with additional adaptation possibilities to fit most suspended ceiling systems on the market.
• OptimAir comes with either one or two air duct connections, positioned lengthwise along the the beam. The number of duct conections are dependent of product length, primary airflow and pressure requirements of the selected beam.
• The requested airflow is factory pre-set
and can also easily be changed on-site.
• OptimAir is equipped with AirFlex supply air deflectors. Each deflector can be individually adjusted, providing for a variety of easily adjusted spread pattern settings in order to achieve a draught-free indoor climate.
Functionality
• The primary air flow is injected into the
plenum box of the beam and distributed
through the supply air nozzles.
• The air is discharged through the nozzles above the coil which creates a low-pressure zone. This low-pressure zone draws ambient room air through the return air grille and into the coil.
• As the return air passes the coil fins, the air is conditioned (i.e.cooling alt. heating), according to the water temperature flowing through the coil.
• The conditioned air then mixes with the injected supply air before it is discharged back into the occupied zone.
• The mix of supply air with conditioned return air is discharged along the ceiling provides an optimal Coanda effect that is always the objective when the occupied zone requires low air velocities.
• The standard version of OptimAir is supplied with adjustable nozzles. With the use of an Allen key the airflow can be adjusted in five steps on each side of the beam. This feature simplifies setting and re-adjustment of the nozzle positions in the event of changed flow requirements.
• This version of OptimAir is intended for applications requiring supply air connection from the long side of the unit, please see OptimAir NF/HF for connection from the short side.
Material options and finishes
• Powder coated finish.
Sizes (mm)
• Supplied in 4 different lengths:
1200/1800/2400/3000
• Supplied with 1 or 2 duct connections placed along the lengthside of product in dimensions Ø100 or Ø125, depending on required air flow and nozzle pressure and in some cases, product size.
Configuration alternatives
• Version for cooling or cooling and heating.
• 2 different battery options: standard battery (M) / high-efficiency battery (L).
• Selectable water connection side: same as the air duct or opposite side.
• Available in versions with 1 or 2 water circuits.
• Adjustable nozzle strips, 5 different positions, 1 per side lengthwise.
Options and accessories
• Integrated control for stand-alone operation or connectivity to parent BMS.
• Complete selection of connection accessories:
– Adjustment damper type ZMC
– Setpoint changer.
– Connection hoses.
– Control valves for water supply.
– Coanda 'cape'.
– Valve actuators.
• Device housing and duct connection made of hot-dip galvanized sheet steel with EPDM rubber gasket.
• Visible parts: casing, frame and perforated front grille made of sheet steel, powder coated in white RAL standard colour. Other colours are available.
• Coil made of copper tubes with aluminum slats.
• Plastic details of Polyethylene.
• For more information about standard materials and colors, see the separate document Product specification which can be downloaded from our website.
• The following information is only a general overview of the of assembly, installation and adjustment procedure. Always refer to the product's operation and maintenence documention (DU-SE/DV-DK) for detailed installation instructions.
• The product is connected to a circular supply air duct. Connection to a straight mounted flexible duct is not recommended.
• Heating and cooling water pipes are installed by a plumbing contractor.
• The unit is supplied with 4 factory-fitted suspension brackets for pendants (one in each corner). Fittings with pendants can be adjusted separately in four directions.
• The product can be suspended using a threaded rod or mounted directly against the ceiling.
• Ensure that no damage occurs to the cooling/heating coil when tightening valves and connections. To avoid this, always use a suitable wrench as counterweight.
• When installing the beam, space should be reserved for opening the front grille and accessing the device for cleaning, inspection and service.
• In order to be able to adjust the operating pressure, the product should be preceded by an comissioning damper mounted in the duct before the unit, e.g. ZMC or SPD, but not an iris-type damper.
• When installing the commissioning damper, requirements for the preceding straight section should be taken into account, see the specific damper's documentation for detailed information.
• The supply air flow, q (l/s or m3/h) is checked by measuring the operating pressure P (Pa) in any nozzle over the nozzle strips or over the measuring rail of the commissioning damper. When the prescribed operating pressure has been measured, the required air flow has been achieved.
• For calculation of K factors, see tables and calculation formula in the operation and maintenance document (DU/DV) of the beam. For K factors with a commissioning damper, please refer to the documentation of the specific damper to be used.
• When the unit is supplied with control options, the product is delivered internally pre-wired from the factory. See separate documentation depending on the current option regarding wiring, commissioning and operation of control and powering components.
