Objetivo

All the reports have been delivered. Some of them (performance testing reports) have shown important scientific breakthrough. Results obtained on the comportment of the wind or performance testing of the photovent system in the test house.
The project has also produced a number of prototypes that could be commercialised in the future. The following prototypes have been produced:
- New improved shape of roof cowl with performance testing in situ and in wind tunnels;
- More efficient sunspace fan with increased airflows
- PV energy supply of the ventilation grilles;
- Wireless communication system of the ventilation system;
- PhotoVent ventilation system - smart ventilation system supplied by PV element communicating via radio waves.
The airflow to realize in all the rooms is constantly calculated to respond to the needs of ventilation. The needs are established on basis of the presence in the rooms, the relative humidity, smoke detection and cooker hood working.
The major objective is to develop PV (photovoltaics) driven energy autonomous and intelligent natural ventilation devices allowing very substantial improvements in indoor air quality and energy use in dwellings and non-domestic buildings. The integration of PV cells in various types of ventilation devices allows the use of intelligent control strategies without grid connection nor use of batteries which have to be replaced. Moreover, it allows also fan assisted ventilation during certain periods of operation. The project will, on the one hand, generate general knowledge on the possibilities and limitations of PV driven smart natural ventilation and on the other hand (and this is for the industrial partners in the project the key issue) will result in the development of several products/systems to be commercialised at the end of the project (ventilation grilles for window use, cowls for roof extraction, sunspace ventilator,...).
Although there are differences in the technologies used in the various European countries, natural ventilation devices show at present a number of more or less common problems:
- variation of air flow rate as function of climatic conditions (wind, temperature difference);
- manual controlled devices are often not opened by users and therefore the IAQ is rather poor;
- often too high ventilation rates in relation to the needs, draught complaints, etc.
Adaptation of the ventilation rates as function of the needs can be achieved in various ways and with various levels of performances:
- on/off control by timer;
- on/off control by presence detectors;
- C02 control;
- others.
These various control strategies are today available for mechanical ventilation systems but not yet for natural ventilation systems. The major problems are:
- the need for wiring between the device and the grid which is difficult to implement and expensive;
- the need of one controller per device or the need of complex wiring in case of central control unit.
New technologies have emerged in other areas which allow to overcome these problems:
- PV cells for power generation in combination with efficient battery technologies;
- wireless control systems.
The project is structured around 6 tasks:
- task 1 is focused on estimating the potential benefits and challenges for PV driven smart natural ventilation designs;
- task 2 specifies for a number of selected systems the requirements to be realised;
- the technical translation is done in task 3 (PV energy support), task 4 (developing control unit) and task 5 (system integration);
- task 6 is focusing on prototype testing and product optimisation;
In order to gain confidence by the decision makers for such relatively complex components, a specific effort is planned for setting up a framework allowing to obtain a technical approval at EOTA level (European Organisation for Technical approval).
