Pollution exists in various forms it can be produced by the human metabolism as we go about our day-to-day lives, our activity or by constitutive dwelling materials.

Humidity: a determining factor for a healthy building and healthy occupants

In liquid or vapour form, water appears as the first cause of problems in the building sector. Small quantities of vapour are enough to cause a direct and indirect effect both on the occupants health and on the building. It is a fact that an amount of moisture ranging between 40% and 60% is essential for the correct functioning of the respiratory system, but too much moisture is harmful for the building and for its occupants. In new or thermally renovated buildings, the lack of ventilation associated with higher insulation and better airtightness can cause significant damage allowing condensation to form on thermal bridges, glazing, vapour control layer fitted on the insulation material, as well as deterioration of the inner walls insulation.

The main causes of excess moisture come from human activity: water vapour produced by breathing and evaporation from domestic activities (washing, cooking, drying clothes etc.), even a large quantity of indoor plants can contribute to raising the inner humidity rate.

A high moisture content generates the presence of bio-contaminators

High relative moisture content in the interior air increases the risk of infestation by dust mites and creates condensation on cold zones and surfaces, which are predisposing factors for fungal and bacterial proliferation. Certain viruses and bacteria, once released by humans or animals, do not survive a long time in the air, but others can remain for months and even years on wet surfaces.

Dust mites can proliferate only under optimal conditions of heat and moisture necessary for their development: 24C and 75% of relative humidity. A drop in the water content of just 5% divides by six the number of dust mites. They completely disappear with relative moisture lower than 45%.

More than 100.000 species of microscopic moulds exist which can generate a large quantity of malodorous volatile organic compounds (VOC). Toxic compounds are also emitted by the deterioration of materials due to excess moisture.

It is thus necessary to control effectively the relative humidity rate in a dwelling by an efficient ventilation system which takes all this into account, in order to stabilise it at a level between 40-50% of relative humidity.

Humidity: a determining factor


VOC: dangerous pollutants

Several studies carried out in various countries throughout the world show that, especially when ventilation is failing, many pollutants are present in our dwellings at thresholds significantly higher than existing standards and WHO recommendations. Products in question include paint, wallpapers, vitrifying products, laminated floor coverings, polishes, aerosol cans, kerosene stoves, and perfumes - among others.

We often associate pollution with the poor quality of the surrounding air, blaming it on industrial emissions and motor vehicles. More than half the time this is not so and it is actually necessary to examine the air quality of the place we live our home. It is regrettable to note that the environment in the house is seldom on the front page of the media, whereas its impact on health is even more important than that of the external environment.

Carbon dioxide (CO2) and other pollutants

The presence of CO2 in a dwelling is mainly due to people breathing.

Studies show that breathing is accompanied by water vapour emissions with a person emitting on average 19 l/h of CO

2 by breathing.

Among the various pollutants found in dwellings accompanied by various degrees of danger to health, let us quote carbon monoxide produced by heating systems and gas cooking and by smoking tobacco; radon, asbestos, nitrogen oxides (NOx) and nitrogen dioxide (NO

2) as the ones

to be particularly concerned about. Other high-risk contributors are bio-contaminants such as dust mites, microbes, mould, etc.

There is only one solution to effectively evacuate all these pollutants: ventilation. It is a vital need and an essential requirement for good health.

Various origins of indoor pollution

Ventilate to adapt to the new energy performances of the buildings

Because of new energy and acoustic requirements for dwellings, new constructions and renovated buildings are now basically an envelope with reinforced insulation and sealing (picture n.2), while older buildings are generally over-ventilated (picture n.1) due to windows and outside walls being leaky due to bad insulation.

Whereas the main thermal issues have been solved compared to older constructions (picture n.1), new problems have appeared. In new building and refurbishments, when ventilation is absent or insufficient, the new air cannot enter, which generates visible problems: air quality decreases (picture n.2) and the excess humidity condenses on the coldest parts of the dwelling.

It is therefore necessary to recreate openings for new air to circulate through the dwelling. To overcome problems, it is

necessary to recreate a ventilation circuit. Fresh new air is brought into the least polluted rooms and polluted air is extracted through wet rooms.

The steps to take:- place air inlets in habitable rooms to introduce air into the dwelling,

- ensure the circulation of the air inside the dwelling by leaving sufficient gap under interior doors,

- place grilles or extract units, connected to a vertical/horizontal duct or to a fan, in wet rooms (kitchen, bathroom and toilets). These will ensure the extraction of the air (the air is able to enter by the habitable rooms only because it is extracted in wet rooms).


Ventilate Right

This is the concept that underlines the design of all Aereco ventilation products. The passive* components of the ventilation system are controlled and activated in various ways according to the needs for each room and what is happening in them. Four principal action modes are distinguished:

Humidity sensitive airflow, created by Aereco in 1984

Manually activated airflow

Airflow activated by a presence detection sensor

Airflow activated by a movement detection sensor

* passive indicates here the components of the network not generating any mechanical energy to ensure ventilation, but simply acting on a bypass section to impose a flow. Fans are known as active components.

Humidity sensitive airflow

Principle: the air cross-section is modulated according to the local relative humidity rate.

As detector and motor of the humidity sensitive products, the V8 sensor exploits a well-known physical phenomenon: the properties of some fabrics lengthen when humidity increases in the air and shorten when the humidity level is lower. On this principle, the 8** polyamide bands of the V8 sensor activate one or more shutters, thereby determining the passage of the air according to the ambient relative humidity rate. The greater the humidity within the building, the more the shutters open. The V8 sensor is isolated from the incoming airflow; it only measures the interior moisture content. Moreover, thanks to a thermal correction, the opening of the shutters is carried out independently of the external climatic conditions.

** also exist in 16 bands (V16)

Aerecos humidity sensitive technology is applied to humidity sensitive air inlets; grilles and extract units located in rooms where the humidity reveals the level of interior pollution (lounge, bedrooms, bathrooms).

humidity sensitive mechanism of an Aereco air inlet

10

Manually activated airflow (1)

Principle: to allow the occupant to increase the extract airflow at times of intensive pollution.

When the humidity is not sufficient to reveal a state of high pollution (use of the kitchen, toilets) the occupant can manually activate peak airflow at the extract unit to quickly evacuate the foul air, bad smells and any excess moisture. This boost can be activated by means of a pushbutton (on-off switch) or by pulling a cord. This function can also supplement a humidity sensitive function on an extract unit. The manual airflow is applied to the extract units with manual boost, in rooms where the humidity is not sufficient to reveal the pollution level (toilets, kitchens, etc).

Airflow activated by a presence detection sensor (2)

Principle: to automatically increase the airflow when a presence is detected in the room.

The presence of somebody in the room is sufficient to automatically activate the Eyebooster presence detector. It then generates the opening of the shutters of the extract unit at maximum airflow. This process is used when moisture is not sufficient to reveal a high pollution level (use of the toilets, random occupation in offices, etc.). This technology makes it possible to carry out energy savings over the period of non-detection, while returning to the basic, or humidity sensitive, airflow.

The Eyebooster module is composed of a pyroelectric sensor that detects the convergent infrared rays through a Fresnel lens. With a 4m zone and a 100 angle of detection, this is very efficient. The infra-red rays concentrated on the sensor are continually analysed; as soon as a variation is perceived, a signal is sent to the electronic board which analyses it and then activates the motor controlling the opening of the extract unit shutters. The presence detection technology is used on extract units and mechanical ventilation terminals in rooms where humidity is not sufficient to reveal the pollution level (toilets, offices, etc).

Airflow activated by an agitation detection sensor (3)

Principle: to control the airflow automatically, proportional to the activity in the room.

The detection mode is the same as for presence (Eyebooster module). The difference is at the level of the analysis of the received signal. The greater zone of detection is divided in a multitude of small zones. The electronic card then analyses the signal received in order to deduct a movement quantity directly related to the number of variations in infra-red radiations registered from one zone to another by intervals of time. The movement detection technology is used to control special air inlets and outlets, or even the working of the fan in rooms where the humidity is not sufficient to reveal the level of pollution (rooms with a great variability of occupation like conference rooms, classrooms, etc.).

A technical response to each need


To achieve good ventilation means you must have a good choice of ventilation techniques. The selected technique depends on the objectives laid down in the project (reduction of heating costs, improvement of the air quality, reduction in running costs, simplicity of maintenance, etc.) but more specifically depends on the environment. This is particularly true in case of refurbishment since the technique must be adapted to existing architecture.

Controlled mechanical ventilation: collective treatment for apartments

Renewal of the air in buildings is ensured by the presence of a fan (3). This is located in the roof or other convenient outside location. In mechanical humidity sensitive ventilation, the air extracted through the extract units (2) from the wet rooms imposes the air renewal of the entire dwelling. Only humidity sensitive air inlets (1) are then able to distribute the new air according to the needs of each main room. The humidity sensitive/presence detection extract units make it possible to distribute the available airflow generated by the fan according to the needs of each wet room, in each dwelling. So rooms, or dwellings, with high requirements in new air promote greater airflow than empty ones.

Which ventilation system?

Controlled mechanical ventilation: individual treatment for apartments

In this case, the fan is placed inside the dwelling. This treatment is also applicable for individual houses as well as apartments. The localisation of the fan inside the dwelling provides the advantage of making it directly accessible, which is a welcome advantage when it comes to maintenance. As before, the air renewal in the dwelling is ensured by the presence of a fan (3). In mechanical humidity sensitive ventilation, the air extracted though the extract units (2) from the wet rooms imposes the renewal of air in the entire dwelling. Only humidity sensitive air inlets (1) are then able to distribute the new air according to the needs of each main room. The humidity sensitive/presence detection extract units make it possible to distribute the available airflow generated by the fan according to the needs of each wet room. So rooms with high requirements in new air promote greater airflow than the empty rooms.

Controlled mechanical ventilation: performance and control


Controlled mechanical ventilation - individual house

Here, air renewal is ensured by the presence of a single fan (3). When silent the fan can be placed in a cupboard/ceiling void, which allows for easy maintenance. Alternatively it can also be placed in the attic when the fan does not have any acoustic properties.

In humidity sensitive mechanical ventilation, the air extracted through the extract units (2) from the wet rooms imposes the air renewal of the entire dwelling. Only humidity sensitive air inlets (1) are then able to distribute the new air according to the needs of each of the main rooms. The humidity sensitive/presence detection extract units make it possible to distribute the available airflow generated by the fan according to the needs of each wet room. So rooms with high requirements in new air dispose of a more important pressure and airflow than the empty rooms.

Controlled mechanical ventilation: performance and control

Passive stack ventilation - collective treatment for apartments

Passive stack ventilation exploits the natural forces (wind and stack effect) in order to renew the air within the dwellings. These forces create a pres-sure in the ventilation duct (3) that starts air circulation from the inside of the dwelling towards the ventilation duct and then outside. The polluted air is then replaced via humidity sensitive air inlets (1) located above windows in habitable rooms (bedrooms and living room).

The air is evacuated through the wet rooms (toilets, bathroom, kitchen) through extract grilles (2): this principle is called sweeping. Depending upon natural forces (wind and stack effect) the passive stack ventilation may be random: it is therefore necessary to control it. The humidity sensi-tive process, while measuring the humidity rate in order to determine the necessary airflow, gives an appropriated answer to the variability of the natural forces. In addition to its energy saving attributes (no fan) the first qualities of this ventilation technique are its acoustics (low air speeds) and simplicity of maintenance.

Hybrid ventilation - collective treatment for apartments

Between passive stack ventilation and mechanical ventilation, the hybrid ventilation is a modern concept which consists in using the components and dimensioning of the passive stack ventilation ducts coupled to a nonpermanent low pressure mechanical assistance. The mechanical assistance is used only when the natural forces are not sufficient to ensure the required airflow. Its start-up is automatic; it can be activated by a temperature sensor or a pressure controller. The air is admitted by humidity sensitive air inlets in the main rooms (bedrooms and living rooms) ; it is evacuated through wet rooms (toilets, bathroom, kitchen) through humidity sensitive extract grilles (2). These components make it possible to control the airflows according to the needs for each room.

The hybrid ventilation aims at combining the advantages of easy maintenance, energy savings, acoustics and reliability of the passive stack ventilation with the airflow performances of the mechanical ventilation.

Hybrid ventilation - Individual house

With hybrid ventilation the stack and the natural forces of the wind in the vertical duct, which is supplemented by fan assistance when necessary, generate air circulation, as described on the previous page.

The air is admitted by humidity sensitive air inlets in the main rooms (bedrooms and living rooms); it is evacuated through wet rooms (toilets, bathroom, kitchen) through humidity sensitive extract grilles (2), which are connected to the assistance fan. These components make it possible to control the airflows according to the needs for each room.

The low energy consumption and low speed of the fan mixed with its nonpermanent use provide real advantages of easy maintenance, energy conservation, great acoustics, airflow performances and reliability.

Hybrid ventilation: the best of each technology for a new concept


3 Aereco process constant airflow ventilation2 Aereco process constant airflow ventilation

To meet this variable need the Aereco ventilation system offers an airflow directly depending on the level of inside pollution of each dwelling. So, the increase of the inner pollution rate, usually accompanied by a humidity rate increase, causes the opening of humidity sensitive air inlets and extract units. In less occupied residences, the reduced use of air bypass sections allows for energy savings.

Pressures and airflows are re-balanced (3)

In collective buildings using in passive stack ventilation, the stack effect naturally tends to support the lower floors at the expense of the higher floors. In order to compensate for the difference in pollution and airflow variations, humidity sensitive air inlets and extract units are open more at the higher levels than at ground floor level.

For similar occupation on each floor, the Aereco process attenuates the airflow variations, whereas the passive ventilation generates greater airflow disparities between the floors.

By offering airflow adapted moment by moment to the needs of the occupants inside the individual dwelling and collective buildings at every moment, Aereco demand controlled ventilation components decrease thermal losses due to ventilation, improve indoor air quality and limit moisture problems caused by condensation.

Invented by Aereco in 1984, humidity sensitive ventilation is considered as a major technological breakthrough among the demand controlled ventilation systems today.

Intelligent distribution of the airflow (1)

The Aereco process optimises air distribution within the dwelling: thanks to the humidity sensitive air inlets, it prioritises channelling of the air towards the rooms, which need it. Thus, it limits thermal losses in unoccupied rooms and it makes good ventilation possible where it is necessary.

Because the number of occupants and activity in the dwellings vary, so does the need for air renewal (2) vary from one moment to the next.

Comfort and energy savings: the secrets of the demand controlled ventilation

A protection against moisture

The rise of the inner humidity rate generated by breathing and human activity in the kitchen or shower can create destructive condensation, which in turn can grow moulds. When the humidity rate increases dangerously, humidity sensitive grilles and extract units open more quickly to evacuate the excess of moisture and eradicate the risk of condensation.

Reduced and controlled heating consumption

Ventilation is often considered to be responsible for a great part of the thermal losses within a dwelling, sometimes up to 50%. If that is true for the majority of traditional ventilation processes, the Aereco system makes it possible to preserve heat in less occupied rooms and dwellings by automatically reducing the airflow. Aerecos performance in this area is recognised by energy regulations in several countries around the world.

Better air renewal for greater comfort

By prioritising ventilation for the places that need it most, Aerecos demand controlled ventilation components largely contribute to the improvement of air quality in the dwelling.

When a main room is occupied, its relative humidity rate increases; air inlets then open more to generate greater airflow and to better evacuate the polluted air. Activity in wet rooms (kitchen, bathroom, toilets, etc.) is accompanied by water vapour emissions; the opening of the extract units increases with the relative humidity rate, increasing the airflow and thus evacuating more quickly polluted air.

Some direct advantages

Monitoring the performance

Continuing measurement, study and analysis of the behaviour of ventilation in order to optimise the performance of our systems is, and will always be, a major concern at Aereco. By comparing theory and practice, field experiments and studies conducted in many countries have helped to increase knowledge

about ventilation and confirm the performance of Aereco ventilation systems. Examples of large scale monitoring such as Performance and HR-VENT have allowed us to test Aereco Mechanical and Hybrid ventilation systems in-situ.

The Performance project, applied on two new buildings erected in Paris and near Lyon (France) in 2007, has given us the opportunity to measure precisely the efficiency of the humidity sensitive Mechanical Exhaust Ventilation in general, and of the Aereco DCV system in particular in a large set of dwellings.

A total of 30 occupied dwellings were monitored over two years from November 2007 to measure representative parameters for energy consumption and indoor air quality. The monitoring has enabled better understanding of the parameters, which can influence the ventilation performance.

CO2 concentrations

As illustrated by the histogram on figure 1, the measurements of CO

2 concentrations show that

the indoor air quality is ensured in a low occupied bedroom (one adult blue) as well as in a high occupied one (four adults pink). The peak of CO

2 concentration has shifted from 700 ppm in

the low occupied bedroom to 950 ppm in the highly occupied one, but even in that case, the 1500 ppm level was not exceeded more than a very few hours in the heating season.

On the chart, figure 2, the efficiency of the humidity sensitive air inlet is confirmed on a representative night time evolution when compared with a simulated fixed ventilation system: while the humidity sensitive air inlet maintains the CO

2 level below 1500 ppm, an

air inlet with a fixed airflow would have led to a CO

2 level of over 2200 ppm.

The monitoring gave, in addition, the opportunity to test the impact of the system in general on the indoor air quality: the fan was stopped during a short period (one month), and the results in terms of CO

2 concentrations were compared

with the other months (with ventilation) of the heating season. The histogram, figure 3, shows as evidence the interest of the ventilation and its positive impact on the IAQ. When the fan was stopped a strong rise in CO

2 concentrations

(above 1900 ppm most of the time) could be observed; moreover, no particular reaction came from the occupants to compensate for the lack of air renewal. This confirms the major role of ventilation on IAQ and shows that occupants are unaware of poor ventilation and dont compensate, for instance, by opening windows.

Thermal losses due to the air renewal

The chart, figure 4, presents the average measured equivalent airflow for energy for every dwelling in the monitoring sample during a complete heating season. The dwellings are sorted by type (number of main rooms). The disparity of measured equivalent airflows results from the adaptation of the ventilation system to various occupations, activities, occupant behaviours and dwelling sizes. The comparison with the French regulatory reference (fixed airflow, grey bars) shows the statistical airflow reduction thus the energy savings obtained by the DCV system. The measured savings on the airflow for this project are evaluated at 30%. But this good result actually hides a better one. A survey showed that most of these dwellings are over-occupied, especially on Paris site. When we extrapolate this result to the statistical average French occupancy for each type of dwellings, the result is around 55% energy savings on the ventilation heat losses. This statistical airflow reduction does not affect the IAQ; just the opposite, a better IAQ in terms of CO

2 and

humidity has been proved, as shown before.

ResultsThe large scale in-situ monitoring of the 30 dwellings has demonstrated the good performance of the tested DCV systems to reach a high level of indoor air quality compared to a fixed ventilation system. The condensation risks are negligible; the monitored system enabled 30% energy savings in comparison to the regulatory fixed airflow on these over-occupied dwellings. An extrapolation to the French average statistical occupancy leads to 55% energy savings on heat losses. Fan consumption has been decreased between 35% and 50% on the two sites. The monitored humidity sensitive ventilation components have shown in-situ

working characteristics in compliance with the laboratory tests, and seasonal airflow Vs RH behaviour favourable to the energy savings. This project has also presented the occasion to validate the hourly evaluation tool (SIREN) used in France by CSTB for Technical Agreements.

With this new complete in-situ monitoring, humidity sensitive ventilation and the Aereco system have shown a high performance in terms of indoor air quality as well as a huge potential for saving energy on ventilation heat losses.

~30% airflow reduction

Performed in France in Nangis (Paris area), HR-VENT was an experiment in occupied housing wherein its exceptional character lies in its size as well as in the implemented measuring tools.

With more than 700 million data recorded during two years from 55 dwellings in five buildings, the experiment has given the opportunity to measure the efficiency of a new concept: a natural humidity sensitive ventilation system assisted by a low pressure fan with intermittent operation. From January 2004 to December 2005, relative

humidity, temperature, pressure and extracted airflow data were recorded each minute, in each wet room of every dwelling, using specifically developed sensors.

Measurements confirmed the performances of the humidity sensitive ventilation system, in particular its capacity to improve indoor air quality, to decrease condensation risks and to limit thermal losses. Its stabilising role has been highlighted: it attenuates airflow imbalances between floors and limits airflow variations over the year by offering a real control of the natural engines (wind and stack effect). The mechanical assistance optimises passive stack ventilation performances: with a consumption of only 5W per dwelling, the fan increases the pressure levels and thus

ensures healthy airflows all year long, and avoids reverse airflow. Coupled with humidity sensitive ventilation, the low pressure mechanical assistance optimises the use of natural forces: average airflows are limited in winter, contributing to energy savings, and positive airflows are assured all year, in particular in hot season. In case of renovation, the hybrid humidity sensitive ventilation system offers comparable airflows with those required by the French regulations for new buildings. Carried out in collaboration with major French institutional partners such as the CSTB and Gaz de France with ADEME financial support, HR-VENT has opened the door to the development of innovative ventilation solutions for residential buildings.

Total airflow control

Not only does the AC external canopy protect the interior of the window from water infiltration when mounted face to an air inlet, it also keeps the airflow under a maximum level to avoid any over-ventilation. A patented internal device limits the maximum airflow when the pressure is too high, which makes the AC canopy particularly suitable for high buildings or windy locations.

The AC external canopy can be installed with fixed or humidity sensitive air inlets while an integrated grille makes it possible to keep flying insects from entering the dwelling.

Protects the internal structure of window against water infiltration.

Limits the air noise in windy conditions*.

Protects the dwelling from volatile insects.

It has the same screw spacing for direct replacement of the fix as AS, ASAM and A-EMM Aereco canopies.

Patented design to control the maximum airflow (1, 2)

The AC external canopy is designed to automatically limit the airflow in case of high pressure thanks to a patented device. The mechanism is composed of a silicon flap that moves according to the airflow. It automatically reduces the air section when the airflow becomes too high (see diagram in data sheet page 60).

Particularly suitable for the EFR manual setting air inlet (3)

Combined with the EFR manual setting air inlet (see technical data page 61), the AC allows the occupant to manage the airflow at every moment: 5 positions from 6 m3/h up to 30 m3/h @ 10 Pa can be set on the air inlet by the user according to need.

Mechanical extract unit


A multifunctional extract unit to provide indoor air quality and energy efficiency

The new BXC incorporates all the functions one could request from an air extract unit: various activation modes such as humidity sensitive, presence detection or switch are available to adapt ventilation to occupants needs. The exhausted airflow is then automatically modulated, in total silence. The range of variable airflows can be set at installation to adapt to special requirements, or to compensate for lack of pressure. Commissioning is also facilitated by the presence of a pressure plug, which enables measurement, and easy calculation of the airflow.

Settable airflow at installation (1)

BXC offers the possibility to set the airflow according to needs or to regulation requirements. The fixed shutter can be set in 6 positions, with an average step of + 10 m3/h (maximum = + 50 m3/h).

Pressure plug to help commissioning (2)

The integrated pressure plug enables measuring the pressure by means of a manometer, to calculate airflow via a table supplied on the installation instructions.

Advanced special versions

BXC is the first extract unit in the world to propose integrated sensors such as CO

2 and VOC. These

innovations are particularly adapted to applications such as schools, offices, gymnasium, mobile-homes, etc. A remote control version is also available. Please contact Aereco for availability, price and information of these models.

Extract unit with presence detection

Detecting presence in an office environment

TDA extract units directly adapt the extracted airflow to the presence detected in the room. A simple initial adjustment of the basic airflow according to the usual number of occupants is sufficient to ensure a permanent air quality. When the room is unoccupied, the airflow is automatically reduced, allowing savings of 50% on thermal losses due to ventilation.

Presence detection: starts the basic airflow as soon as a presence is detected.

Easy to maintain: removable grille for easy cleaning.

Smile: you have been detected (1)

The Eyebooster module is composed of a pyroelectric sensor that detects the convergent infrared rays through a Fresnel lens. With a 4 m zone of detection and a 100 angle of detection, this is very efficient. The infra-red rays concentrated on the sensor are continually analysed; as soon as a variation is perceived, a signal is sent to the electronic board which analyses it and then activates the motor controlling the opening of the extract unit shutters. The presence detection technology is used on extract units and mechanical ventilation terminals in rooms where humidity is not sufficient to reveal the pollution level (toilets, offices, etc). Note that the electronic board is able to tell the difference between human heat and heater or lights.

The basic airflow is started as soon as a presence is detected: the TDA returns to the reduced airflow 20 minutes after the last detection. So, when the room is empty, heating energy is saved (up to 50% compared to fixed ventilation with the same air quality).

Simple adjustment determines occupant numbers (2)

A cursor makes it possible at any time to set the number of people in the office, which determines the basic airflow activated during the detection process (from 25 to 100 m3/h).



Detecting movement in offices

The MDA module directly adapts the airflow according to the level of movement detected in the conference room, classroom, etc. Integrated in the duct network and located between a fan, a regulation module and a diffuser, the MDA is controlled by movement detectors covering the zones of activity in the room. So, the MDA adapts the airflow proportionally to detected movement. The resultant airflow is moment by moment perfectly adapted to the needs of air renewal and makes it possible to obtain important energy saving. According to the occupation scenario, it is easy to obtain up to 65% of energy saving in comparison with fixed airflow ventilation.

Movement detection: modulates the airflow according to the detected movement level.

Airflow is diffused (no nuisance of draughts).

Ventilate according to movement

The MDA module works according to the same principle as the Eyebooster module (see pages concerning TDA product). The difference is in the level of analysis of the received signal. The greater detection zone is cut into a multitude of smaller zones. The electronic board then analyses the received signal to deduct a movement quantity directly linked to the number of radiation variations registered from one zone to another by intervals of time.

Discreet integration

Hidden in the ductwork, the MDA is invisible and can be adapted to the existing dimensions of ventilation networks for office buildings such as conference room, classroom, etc. Only the connected diffuser and the lenses are visible.

Optimising passive stack ventilation performances

The VBP is easily installed in the outlet of passive stack ventilation ducts. Thanks to an astute adaptation box, the VBP very low-pressure fan can maintain satisfactory airflow all year long in a basic installation using passive stack ventilation. Combining efficiency and energy saving, it avoids reverse airflow particularly in mid-season and summer when the risks are more likely. Its airflow performances make it possible to equip apartments up to 7 levels using existing ducts as it works on low pressure.

Low energy consumption: efficient motor and electronic control.

Allows an operation in passive stack ventilation when stopped (no pressure losses).

Silent: only 46 dB (A)* thanks to its low speed working.

* Lw @ 8 V, r = 4 m.

Easy to install: by the mean of adaptable parts.

Controllable by temperature or wind speed.

Unique patent for operation in passive stack ventilation (1)

The singular design of the VBP means it will not create any additional pressure loss when stopped: its central blades are parallel to the airflow and static paddles located outside the vertical airflow generate the pressure under operation. This allows normal operation of the passive stack ventilation when the fan is off.

Electronic control per stack of dwellings (2)

In VBPms version (management system), the assistance fan is managed per stack of dwellings: A box controls the simultaneity of the operation and the power of several connected fans. The device also controls fan speeds according to the outside temperature or wind speed (different versions).
