Demand Controlled Ventilation

Marc Jardinier, CEO of Aereco S.A. Innovation that excels in air quality and energy savings Everyone knows that air quality is a determining factor when it comes to comfort at home and in the office. Additionally, modern building regulations make cutting energy costs a major priority. Aereco has been meeting these demands by designing and manufacturing innovative demand controlled ventilation units for more than 25 years when the company proved itself to be a forerunner by inventing the humidity sensitive ventilation system. Today, it continues to pursue its research, consistently offering new...

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,...

Humidity: a determining factor A high moisture content generates the presence of biocontaminators 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:...

Various origins of indoor pollution Carbon dioxide (CO2) and other 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...

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. necessary to recreate a ventilation circuit. Fresh new air is brought into the least polluted rooms and polluted air is extracted through wet rooms. Whereas the main thermal issues have been solved compared...

humidity sensitive mechanism of an Aereco air inlet ‘Ventilate Right’ Humidity sensitive airflow 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: Principle: the air cross-section is modulated according to the local relative humidity rate. Humidity sensitive airflow, created by Aereco in 1984 Manually activated airflow Airflow activated by a presence detection...

A technical response to each need 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...

Which ventilation system? 1. Air inlets 2. Extract units 3. Fan 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.
