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.
The extract air heat is used for warming up of the supply air stream in the high-efficient plate heat exchanger.

The units offer energy-efficient ventilation for cottages and flats and are compatible with round Ø 125 mm air ducts.

FILTER

Supply and extract air flows are purified through G4 panel filters.
For extra supply air filtration a F8 filter is available as a specially ordered accessory.

CASING

The casing is made of 15-26 mm thick expanded polypropylene (EPP) sheets, possessing high heat- and sound-insulating properties.

FANS

High-efficient electronically commutated motors with external motor and impeller with backward curved blades.
Such motors are the most state-of-the-art energy saving solution.

EC motors are featured with high performance and total speed controllable range.
High efficiency reaching 90 % is the premium advantage of the electronically commutated motors.

HEAT EXCHANGER

The VUT 270 V5(B) EC units are equipped with a counter- flow polystyrene heat exchanger.
In the cold season the extract air heat is transferred to the intake air stream which reduces 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 outside air heat is transferred to the exhaust air stream.
This allows for a considerable reduction of the supply air temperature which, in its turn, reduces the air conditioning load.

The VUE 270 V5(B) EC units are equipped with a counter-flow heat exchanger with an enthalpy at the core.
In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy.
Heat recovery minimises heat losses from ventilation.
In the warm season the outdoor air heat and moisture are transferred to the exhaust air stream through the enthalpy.
This enables considerable reduction of the supply air temperature and humidity which, in its turn, reduces the air conditioning load.

BYPASS

The VUT/VUE 270 V5B EC units are equipped with a bypass for summer ventilation (cooling of the premise with a cool outside air).

AUTOMATION

The VUT/VUE 270 V5B EC A21 units are equipped with control system.
The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
Remote control panel is not included in the delivery set and is available as specially ordered accessory.
The unit is controlled via Wi-Fi by means of the VENTS AHU mobile application that must be downloaded.
The VUT/VUE 270 V5B EC A14 units are equipped with integrated control system and wall-mounted sensor control panel A14 with LED indication.

FREEZE PROTECTION

INSTALLATION

For VUT/VUE 270 V5B EC A14 the freeze protection is realized by means of shutdown the supply fan.
For VUT/VUE 270 V5B EC A21 the freeze protection is realized by means of turning the preheater on.

The units are designed for wall and floor mounting.
The access for unit and filter maintenance is available on the right and left side.

Calculation of air temperature downstream of the heat exchanger:

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) [%]
