New concept of balanced thermal dynamic system

Studies on buildings have shown that airtightness and insulation increased in family buildings and detached houses too, due to new thermal regulations. In the same time, studies concerning health and indoor air quality have shown that the need of fresh air will increase too. Ventilation becomes the only way to avoid booth moisture and a stuffy atmosphere: in urban areas, it becomes impossible to open the windows due to breaking and entering, filtering the air is needed, and inlet devices on windows are prohibited due to much outside noise.Therefore, ALDES developed a preheated and refreshed air balanced system witch assure the all part of the thermal lose, winter and summer, supported by the air without improving the air flow needed for indoor air quality and without recycling the indoor air .The objectives of this paper is to present both this new air quality and comfortable concept and measurementson an experimental building consisting of eight dwellings south of France. We present both summer and winter results recording each five minutes in each room. We analyse the performances of this concept in regard to comfort and spreading.Results are very heartening and better than French requirements .
