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 extraction.
  • 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).
CASING  
  • Made of high-quality polymer coated steel, internally filled with 20, 25, 30 or 40 mm (depending on the unit model) mineral wool layer for heat and sound insulation.
FILTER  
  • Supply and exhaust air flows are purified through panel filters with filtering class G4 and F7, respectively.
  • Filters with G4 filtering class are used for supply and exhaust air purification in the VUT/VUE 250 VB EC units.
  • F7 filter is available as an option for supply air filtration.
FANS  
  • The units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with backward curved blades.
  • These state-of-the-art motors are the most advanced solution in energy efficiency today.
  • EC motors are characterised with high performance and optimum control across the entire speed range.
  • In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.
HEAT EXCHANGER  
  • The VUT V(B) 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 V(B) 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 heat exchanger reducing the heat losses from ventilation.
  • The ambient air heat and moisture are transferred to the exhaust air stream through the enthalpy heat exchanger 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.


BYPASS  
  • The VUT/VUE VB EC units are equipped with a bypass for summer ventilation (air cooling by the cool air from outside).
AUTOMATION  
  • The VUT/VUE V(B) EC A21 units are equipped with a built-in automation system.
  • The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
  • The remote control panel is not included in the delivery set (available separately).
  • To control the unit via Wi-Fi, download the VENTS AHU mobile app.

 

  • The VUT/VUE V(B) EC A14 units have an integrated control system with a wall-mounted control panel A14 with a LED indication.
  • The VUT 250 V EC units are available only with the A14 automation system.

FREEZE PROTECTION  
  • In the VUT/VUE 160/350/550 VB EC A21 units it is possible to connect a preheater to protect the unit from freezing.
  • The VUT 250 VBE EC A21 unit is equipped with a built-in preheater for frost protection.

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) [%]
