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.
FILTER FANS
  • Supply and exhaust airflows are purified through panel filters with filtering class G4 and F7, respectively.
  • Supply and exhaust airflows in the VUT/VUE 200 VB EC units are purified through G3 filters.
  • 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 and 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 counter-flow heat exchanger with an enthalpy membrane.
  • 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.
  • Consequently, it is the ambient air heat and moisture 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 a heat- and sound-insulated layer of mineral wool.
  • The VUT/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 units may be equipped with two types of automation: A14 or A11.
  • The VUT/VUE VB EC A14 models have the A14 sensor control panel with LED indication.
  • The VUT/VUE VB EC A11 units have the LCD sensor control panel PU SENS 01.

  • Two ways of freeze protection are available:
 
  1. Supply fan stopping. The heat exchanger freeze protection operates as follows: in case of freezing danger determined by the temperature sensor, the supply fan is turned off to let extract air warm up the heat exchanger. After freezing danger is no longer imminent, the unit reverts to the standard operation mode.
  1. Pre-heating. 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 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) [%]
