School in Kniazhychi: 6,000 m³/h shelter ventilation built from Aerostar components

Photo 01: Ventall completed a full scope of school ventilation works in Kniazhychi, installing outdoor supply and exhaust units with air-filtration sections. The mains are made of rectangular galvanized steel ducts mounted on reinforced brackets and provide the required air exchange in classrooms. Sealed wall penetrations and quality shut-off fittings improve energy efficiency and prevent heat loss in winter.

Photo 02: The photo shows the building of the general education school in Kniazhychi. Ventall completed a full package of engineering works in the school's shelter. The technical part of the project included installation of a supply and exhaust unit with high-capacity EC fans and aluminum plate heat exchangers for efficient heat recovery. The system is fully automated: pressure sensors monitor filter condition, ensuring clean air supply during long stays in the shelter.

Photo 03: The photo shows the internal communications of the ventilation system in the shelter of the Kniazhychi school. Ventall installed rectangular main ducts and flexible round branch lines. The entire network is covered with foil insulation, which is important for basement spaces: it prevents condensation on the metal surface and retains the temperature of supply air preheated by the heat-recovery unit. Secure ceiling mounting keeps the system stable, and its layout enables even air renewal in the desk areas.

Photo 04: The photo shows the internal duct network in the shelter classroom. Ventall implemented a mixed scheme: galvanized-steel main ducts are combined with sections wrapped in foil insulation. This configuration prevents supply air from cooling during transport from the heat-recovery unit and eliminates condensation indoors. The system operates together with a central supply and exhaust unit equipped with energy-efficient EC fans to maintain the required oxygen level even when the hall is full.

Photo 05: The photo captures a section of the supply ventilation in the school shelter. Ventall installed a rectangular galvanized-steel main duct with high mechanical strength and durability. A double-layer adjustable grille is integrated into the side of the duct, allowing precise control of airflow direction and throw for a comfortable microclimate without drafts. The system is securely fixed to the reinforced-concrete slab with reinforced threaded rods and traverses for stability under intensive use.
