SYSTEM OVERVIEW VENTILATION DEVICE IV-TWIN+
2 System overview Ventilation device iV-Twin+
The iV-Twin+ ventilation system was developed as a single room unit with heat recovery for separate ventilation of separate rooms or as a supplementary unit to existing ventilation devices. It is designed for the ventilation of living rooms and bedrooms in detached houses and apartment buildings, hotels and guesthouses, rooms in public facilities and workrooms in office buildings.
As a single room device, the iV-Twin+ does not require paired operation. The
creation of a spatial connection through overflow measures is not necessary.
The iV-Twin+ can therefore also be used in classic extract air rooms such as
kitchens, utility rooms, bathrooms and bathrooms. It is
suitable for installation in new buildings as well as for retrofitting in old
buildings. The installation is generally carried out in the outer wall.
A lockable inner panel discreetly covers the iV-Twin+ visually from the
interior. In the outdoor area, a freely selectable cover conceals the
components of the ventilation unit. The air volume
flow separators integrated into the inner panel and the outer cover ensure
that there is no mixing of different air flows outside the wall sleeve.
The standard lenght of the separating element is 765mm.The standard length of the wall sleeve is 495 mm. For larger wall thicknesses, a wall sleeve with a length of 745 mm or 495 can be ordered. Both versions can be shortened on site.
The ventilation unit is controlled via one of the following controllers1) of the inVENTer system:
· Pure
· MZ-Home
· sMove
Components · Separating element for the wall sleeve · Wall sleeve · External termination · Pollen and activated carbon filter (optional) · Inner panel

2.2 Functions
Ventilation device iV-Twin+
The iV-Twin+ ventilation device is used to ensure the ventilation of living
spaces. In addition, installation in classic extract air rooms is possible.
The integrated heat accumulator ensures optimum heat recovery at maximum air
volume flow.
As a single room device, the iV-Twin+ combines a supply air and extract air
device in one. To ensure that the ventilation system functions correctly and
that the pressure stability in the room is guaranteed, the supply air volume
must correspond to the exhaust air volume at all times. A separating element
vertically divides the wall sleeve into two airtight chambers. Each chamber
contains a fan unit and a heat accumulator in half-cylinder geometry.
Due to a high pressure build-up and the active speed control of the motor
(integrated wind pressure stabiliser) in the Mini-Xenion reversing fan, the
air volume flow in the system is kept almost constant even in the event of
pressure fluctuations caused by the weather.
In order to ensure the full functionality of the ventilation unit throughout
the year, a temperature monitor is integrated in the Mini-Xenion reversing
fan. This measures the temperature of the air flow at the fan. If the
temperature at the fan falls below + 5 °C, the reversible fan is automatically
switched to extract air mode for 4 cycles. This allows the thermal accumulator
to heat up again and prevents cooling of the interior due to cold supply air.
During this phase, the operating mode that has been set on the controller is
ineffective. Subsequently, the controller switches the ventilation device back
to the originally selected mode.
The most important components of the iV system are the ceramic thermal
accumulator, the reversing fan, air guiding vanes for straightening the air
volume flow, filters for different requirements, a closable inner panel and an
outer cover. A control device (controller) completes the system.
The operation of the iV ventilation systems is intuitive with the matching
inVENTer controllers. Different operating modes or air volume flows can be set
individually. The iV-Twin+ must be equipped with its own sMove or Pure
controller. It is also recommended to consider the MZ-Home Controller as a
separate zone.
The iV-Twin+ ventilation unit can be installed in area 1 according to VDE
0100. It meets the requirements of protection class IPX4. Please note the
different installation situations (chapter 4.8). If installed incorrectly, the
requirement will not be met.
In rooms with humidity entry, it is suggested to install a separate hygrostat
(sMove, Pure) or the humidity sensor (MZ-Home) in the room.
SYSTEM OVERVIEW VENTILATION DEVICE IV-TWIN+
Function of the iV-Twin+ in reverse mode In
70 s
Figure 2: Function of the iV-Twin+ in reverse mode The ventilation system
works according to the principle of regenerative heat recovery. The integrated
thermal accumulator is charged with the thermal energy of the room air as it
flows externally (extract air). After 70 seconds, the reversing fan changes
the direction of rotation each time. After the direction of rotation has
changed, the heat accumulator releases the stored heat energy to the incoming
fresh air (supply air). The two fans are each operated as a pair in push-pull
mode: One reversing fan conveys supply air into the interior, while the other
reversing fan conveys stale exhaust air out of the interior at the same time.
Function of the iV-Twin+ in exhaust air mode
If the ventilation mode is selected on the controller, the iV-Twin+
ventilation unit operates in extract air mode. Both reversing fans are
switched to extract air mode at the same time, i.e. both fans simultaneously
convey used extract air from the interior to the outside. In this operating
mode, there is no heat recovery. It is particularly recommended for the rapid
removal of moisture and odour load peaks.
