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

· Half cylinder heat accumulator (2x) · Fan unit with dust filter class

SYSTEM OVERVIEW VENTILATION DEVICE IV-TWIN+
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.
