APPLICATION
The VAV units with integrated silencer are used in ventilation systems to improve comfort and reduce energy consumption. The integrated silencer ensures a low noise level in the room and these units are insulated so that no condensation occurs with cold primary air and reduces the radiated noise. Another advantage of these units is that the measuring reticle is in the interior of the units, so the unit does not need a straight flow. The unit is controlled by a room sensor with temperature and/orCO2 or from the building management system and varies the air volume based on cooling demand and/or ventilation requirement.
This results in significant savings in fan energy because, when there is little or no cooling demand, the valve can be partially or even completely closed.
FEATURES AND BENEFITS
- Air flow sensor: the FloXact™ has a linear gain factor of at least 2.5x, and measures the average over a large number of measuring points according to the Log-Tchebycheff method. These units do not require straight flow and can accurately control from 0.4 m/s inlet speed.
- Housing: Magnelis steel (S235+ZM310). This steel with a modern surface treatment with a very high corrosion resistance. It is less harmful to the environment and has a beautiful appearance (comparable to anodized aluminum). Airtightness Class-D according to LUKA and EN-1751.
- Insulation: sandwich construction consisting of mineral wool with woven fiberglass cover and closed cellular rubber against the inside of the metal jacket.
- Valve blade: Extruded aluminum sheets 100 mm. Airtightness Class-4 according to LUKA and EN-1751
- Controller: As standard, we supply the VAV units without control equipment or complete with Belimo controllers. Air-Concepts also installs control equipment supplied by third parties such as Priva, Johnson Controls, EasyIO, Distech, KMC, Sauter, Siemens, Honeywell, etc.
