  • Application
  • Description

Application

  • Ventilation and extract ventilation of rooms, preferably rooms with a depth up to 6 m
  • 2-pipe or 4-pipe heat exchangers enable good comfort levels
  • Supply air discharge from supply air slots
  • Energy-efficient solution since water is used as a medium for heating and cooling
  • For new buildings and refurbishment projects
  • Installation below the ceiling slab and near an external wall
  • Typical applications include classrooms in schools, playrooms in daycare facilities, smaller meeting rooms and offices with a high air change rate

Special characteristics

  • Air-water heat exchanger as 2-pipe or 4-pipe system, with G½" union nuts and flat seals
  • Cross flow heat exchanger for heat recovery, including bypass damper with electric actuator
  • Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows
  • The condensate drip tray is useful if the temperature temporarily falls below the dew point
  • Decentralised ventilation unit for high volume flow rates
  • Ceiling plate with height-adjustable frame (up to +29 mm) and integral supply and extract air slots
  • 2 energy-efficient and acoustically optimised EC fans with low specific fan powers, SFP = 1 according to EN 13779
  • Meets the hygiene requirements of VDI 6022
  • Compact construction, hence particularly suitable for refurbishment projects
  • Demand-based ventilation and extract ventilation is possible by means of monitoring the room air quality and with dedicated control equipment

Variants

  • SCHOOLAIR-D – volume flow rates: 150, 200, 250 and 320 m³/h, with cross flow plate heat exchanger for heat recovery

Useful additions

  • Modular control system X-AIRCONTROL, specially for decentralised ventilation systems
  • Connecting hoses

Construction features

  • 2 energy-efficient EC fans with low specific fan powers, SFP = 1 according to EN 13779
  • The supply air is discharged to the room as an inducing displacement flow from the supply air slots
  • The extract air is removed through slots

Materials and surfaces

  • Casing, ceiling plate, filter chamber cover, fans and hanging brackets are made of galvanised sheet steel
  • Heat exchanger with copper tubes and aluminium fins
  • Plate heat exchanger (heat recovery) made of aluminium
  • Casing is powder-coated RAL 9005, black, or in any other RAL colour; gloss level 70 %
  • Ceiling plate powder-coated pure white (RAL 9010), gloss level 50 %, or in any other RAL colour, gloss level 70 %
  • Supply and extract air slots made of aluminium, air control blades made of polystyrene
  • F7 filter medium made of moisture-resistant glass fibre paper (certified by Eurovent)
  • Mineral wool lining to DIN 4102, fire rating class A, faced with glass fibre fabric as a protection against erosion, effective with airflow velocities up to 20 m/s
  • Closed cell sealing strips

Functional description

Decentralised supply air and extract air units for room ventilation and extract ventilation and for dissipating cooling loads and heat loads.

An EC centrifugal fan takes in the fresh air which then flows through the motorised shut-off damper and the F7 filter.

Once the fresh air has passed the fan, it flows through the recuperative heat exchanger for heat recovery; it is possible to bypass the recuperative heat exchanger in order to protect it, or when it is sensible with regard to energy efficiency.

If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room from the supply air slot

The extract air is removed through an extract air slot, passes a filter, then flows through the heat exchanger (heat recovery), the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air.
