Heat recovery AHU VENTS VUT/VUE 180 P5

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 150 mm air ducts.

FILTER

CASING

The built-in G4 supply filter and G4 extract filter provide air filtration.
A F7 supply filter (specially ordered accessory) may be used for efficient supply air filtration.

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

FANS

Single-phase three-speed external rotor motors with centrifugal impellers and forward curved blades.

HEAT EXCHANGER

The VUT 180 P5 units are equipped with a counterflow 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 180 P5 units are equipped with a counterflow heat exchanger with an enthalpy membrane at the core.
In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy membrane.
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 membrane.
This enables considerable reduction of the supply air temperature and humidity which, in its turn, reduces the air conditioning load.

CONTROL AND AUTOMATION

The unit is equipped with integrated control system.
It can be supplied either with the mechanical threespeed speed controller P3-1-300 or the sensor threespeed speed controller SP3-1, power cable with Europlug XP mains plug.
The service side of the unit has a removable inspection door with hand screws to enable heat exchanger and filter cleaning and replacement.
The control unit is located inside of the unit casing.
The power cable and the ground cable are connected to the control unit via the cable glands on the side on the unit.

FREEZE PROTECTION

INSTALLATION

The freeze protection is realized by means of shutdown the supply fan as follows: in case of freezing danger communicated by the temperature sensor the supply fan is turned off to let the heat exchanger defrosting with the extract air heat.
After freezing danger is no longer imminent, the unit reverts to the standard operation mode.

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
