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 is purified in panel filters with filtering class G4 and F7, respectively.
Filters with G3 filtering class are used for supply and exhaust air purification in the VUT/VUE 200 VB EC units.
Supply air in the VUT/VUE 250 VB EC units is purified by the G4 and F7 filters.
Exhaust air is purified by the G4 filters.

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.

CASING

BYPASS

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.

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 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 200 V(B) EC, VUT 250 V EC units are available only with the A14 automation system.

FREEZE PROTECTION

Freeze protection is provided by the shutdown of the supply fan.

In the VUT/VUE VB EC A21 units it is possible to connect a preheater to protect the unit from freezing.

t = t_outd + k_hr * (t_extr - t_outd) / 100,

where
t_outd - outdoor air temperature [°C]
t_extr - extract air temperature [°C]
k_hr - heat exchanger efficiency (according to the diagram) [%]
