Description

DESCRIPTION

CASING

The air handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extract.

The casing is made of expanded polypropylene (EPP) possessing high heat- and sound-insulating properties.

FILTER

FANS

Two built-in G4 and F7 filters provide efficient supply air filtration.
The G4 filter is used for extract air filtration.

Efficient electronically commutated motors with external rotor and impeller with forward curved blades.
Such motors are the most state-of-the-art energy saving solution.

HEAT EXCHANGER

The VUT 180 P5B EC units are equipped with a counter-flow polystyrene heat exchanger.

The VUE 180 P5B EC units are equipped with an enthalpy counter-flow heat exchanger.

BYPASS

AUTOMATION

The VUT/VUE 180 P5B EC A14/A21 units are equipped with a bypass for summer cooling.

FREEZE PROTECTION

For VUT/VUE 180 P5B EC A14 the freeze protection is realized by means of shutdown the supply fan.
For VUT/VUE 180 P5B EC A21 the freeze protection is realized by means of turning the preheater on (available as an accessory).

MOUNTING

The unit is designed for suspended ceiling, wall horizontal or vertical installation using the fixing brackets.
The mounting position of the unit must provide service access for maintenance and repair.

The VUT/VUE 180 P5B EC A21 units are equipped with integrated control system.
The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
The unit is controlled via Wi-Fi by means of the VENTS Home mobile application that must be downloaded.

The VUT/VUE 180 P5B EC A14 units are equipped with integrated control system and the A14 wall-mounted control panel with LED indication.

Calculation of air temperature downstream of the heat exchanger:

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

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