X-CUBE SCHOOLAIR-V  

Supply and extract air unit with heat exchanger and heat recovery unit, secondary air option, for vertical installation on an external wall, e.g. adjacent to a window

Ready-to-operate decentralised ventilation unit that provides good comfort levels, used for the ventilation and extract ventilation of rooms such as classrooms in schools

  • Acoustically optimised EC fans with low specific fan powers, SFP-1 according to EN 13779
  • Recuperative plate heat exchanger (air/air), including bypass damper with electric actuator (open-close)
  • Alternatively: Rotary heat exchanger for heat recovery (air/air), including bypass with electric actuator (modulating or open-close)
  • Heat exchanger for heating and cooling as 2-pipe or 4-pipe system
  • Unit base of approx. 0.24 m²
  • Easy filter change, no tools required
  • Condensate drip tray with or without condensate drain
  • Motorised shut-off dampers, normally closed (NC)
  • Automatic switching to secondary air mode (based on air quality)


Optional equipment and accessories

  • Modular control system FSL-CONTROL II, specially for decentralised ventilation systems
  • Demand-based fresh air volume, free cooling and night purge, depending on control strategy
  • Variable heat recovery
  • Powder-coated RAL 9005 (black)

Application

Application

  • Ventilation and extract ventilation of rooms with a depth up to approx. 6 m
  • 2-pipe or 4-pipe heat exchangers enable good comfort levels
  • Inducing displacement flow
  • Energy-efficient solution since water is used for heating and cooling
  • For new buildings, refurbishment projects and revitalisation projects
  • Vertical installation on the façade system or an external wall
  • Typical applications include classrooms in schools, playrooms in daycare facilities, meeting rooms and offices with a high air change rate

Special characteristics

  • Decentralised ventilation unit for high volume flow rates
  • Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows
  • Demand-based ventilation and extract ventilation is possible by means of monitoring the room air quality and with dedicated control equipment
  • The type of heat recovery unit depends on the unit variant: cross flow plate heat exchanger, cross counter flow plate heat exchanger including bypass damper with electric actuator (open-close or modulating) or rotary heat exchanger
  • Heat exchanger as 2-pipe or 4-pipe system, with G½" union nuts and flat seals
  • Meets the hygiene requirements of VDI 6022
  • Filter class: F7 for fresh air, G3 for extract air
  • Easy filter change with quick release fasteners, no tools required
  • Condensate drip tray with or without condensate drain
  • Compact construction, hence particularly suitable for refurbishment projects
  • Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality (measured with the integral VOC sensor, for example) is between the previously defined range. The unit always starts in secondary air mode, which is more energy efficient.
  • Depending on the unit, an enthalpy heat recovery unit may be used

Functional description

Decentralised supply and extract air units for room 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 heat exchanger for heat recovery; it is possible to bypass the heat exchanger in order to pect 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 as a displacement flow.

The extract air first passes a G3 filter, then flows through the heat exchanger, the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air.

If the room air quality is good, the unit can be operated in secondary mode only.
