Description
Description
DESCRIPTION  
  • The air handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extract.
  • During operation the extract air heat is transferred to the supply air stream by the highly efficient plate heat exchanger.
  • The units are designed for energy efficient ventilation of cottages and flats and are compatible with round air ducts (Ø 125, 160 and 200 mm).
FILTER FANS
  • Supply and exhaust air flows are purified through panel filters with filtering class G4 and F7, respectively.
  • Supply airflows in the VUT/VUE 250 VB EC units are purified through G4 and F7 filters.
  • Exhaust airflows are purified through G4 filters.
  • The units are equipped with high-efficient EC motors with an external rotor with backward curved blades.
  • These state-of-the-art motors offer the very best in energy efficiency today.
  • The high efficiency (up to 90 %) is a definite advantage of EC motors.
HEAT EXCHANGER  
  • The VUT VB EC units are equipped with a counter-flow polystyrene heat exchanger.
  • In the cold season the extract air heat is captured and transferred to the supply air stream which reduces the ventilation-generated heat losses.
  • This can lead to formation of condensate that is collected in a special drain pan and discharged into the sewage system.
  • In the warm season the ambient air heat is transferred to the exhaust air stream.
  • This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load.

  • The VUE VB EC units are equipped with a counterflow enthalpy heat exchanger.
  • In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy membrane reducing the heat losses from ventilation.
  • The ambient air heat and moisture are transferred to the exhaust air stream through the enthalpy membrane in the warm season.
  • This allows for a considerable reduction of the supply air temperature and humidity which, in turn, reduces the air conditioning load.

CASING BYPASS
  • Made of high-quality polymer coated steel, internally filled with 20, 30 or 40 mm (depending on the unit model) mineral wool layer for heat and sound insulation.
  • The VUT VB EC and VUE VB EC models are equipped with a bypass which can be opened if there is a need to cool down the ventilated area with cool intake air without heat recovery.
CONTROL AND AUTOMATION  
  • The VUT/VUE VB EC A11 units have the LCD sensor control panel PU SENS 01.

  • Two ways of freeze protection are available: 
  • Supply fan stopping.
  • Preheating: when the outdoor air temperature drops below -3 °C, the heat exchanger freeze protection algorithm is activated by the NKP electric heater that heats the intake air.
  • The heater power is continuously adjusted by the automation system in order to prevent condensate freezing in the heat exchanger. 
MOUNTING  
  • The units are designed for wall or floor mounting.
  • The access for unit and filter maintenance is available from the front panel.
  • During mounting stage the front and the back panels can be reversed providing either left-handed or right-handed unit mounting.

Calculation of air temperature downstream of the heat exchanger:

t = toutd + khr * (textr - toutd) / 100,

where
toutd - outdoor air temperature [°C]
textr - extract air temperature [°C]
khr - heat exchanger efficiency (according to the diagram) [%]
