Capteur solaire thermique

Résumé

Un capteur solaire thermique (ou capteur solaire, ou capteur hélio-thermique, ou encore panneau solaire) est un dispositif conçu pour recueillir l'énergie solaire transmise par rayonnement et la transférer à un fluide caloporteur (gaz ou liquide) sous forme de chaleur. Cette énergie thermique peut ensuite être utilisée pour le chauffage de bâtiments, pour la production d'eau chaude sanitaire ou encore dans divers procédés industriels. Cette technologie est différente de celle des panneaux photovoltaïques, qui transforment la lumière (les photons) en électricité. Les deux peuvent toutefois être combinées dans des panneaux photovoltaïques et thermiques. Principes généraux de fonctionnement Un capteur solaire thermique est un échangeur de chaleur qui transforme le rayonnement solaire en énergie thermique. Il se distingue d'un échangeur classique sur plusieurs points. La densité surfacique du flux énergétique solaire (irradiance) à la surface de la Terre est variable et fa

The paper presents selected results of an investigation over possible ways to improve Building Integrated Solar Thermal systems (BIST) on the formal level. It shows the results of a European survey intended to help defining quality in the architectural integration of BIST. A few criteria of integration are derived and presented as guidelines intended to support architects in their integration design work. Finally the paper describes a methodology for the formal development of solar thermal collectors responding to both energy and architectural needs.

Architectural Integration and Design of Solar Thermal Systems

Maria Cristina Munari Probst, Christian Roecker

Although solar thermal systems are technologically mature and cost effective, they have not yet been sufficiently used in building design, where they should be playing a greater role in the reduction of fossil-fuel consumption. One main hindrance to adoption is the generally low architectural design quality of the building integration of these thermal systems. As confirmed by the application of photovoltaic elements in buildings, improving the architectural quality of building integrated system leads to the adoption of a given solar technology even more than price reduction or technical advances. And in the case of solar thermal collectors, which for technical reasons have to be mounted very close to the point of consumption, the architectural integration issue becomes determining. Starting from a definition of architectural integration quality and related criteria, this book will help both architects and manufacturers improve their design work. Architects will find recommendations to optimize the integration quality, thus making the best out of the generally limited flexibility and low formal quality of presently available collectors; and examples of inspiring integration and innovative products are presented. For manufacturers, the book will provides a set of guidelines for the development of new multifunctional and flexible products conceived from the outset for building integration, thus improving the market offer.

Development of solar ventilated façade system for building energy retrofit

Alessia Giovanardi, Maria Cristina Munari Probst, Christian Roecker

In the perspective of setting ambitious targets for new buildings energy performance and of introducing new approaches to retrofit existing buildings, the implementation of solar thermal collectors into façade becomes very interesting Several research activities are currently pursued to facilitate the architectural integration of collectors in the building skin, , mainly in the glazed flat plate collectors’ domain. This paper presents a new approach for unglazed flat plate collectors,. The idea is to develop a new collector conceived from scratch as a building element, either façade metallic cladding or roof covering. The base element is an absorber whose hydraulic circuit is made using the “roll bond” technique. The building element chosen can then be formed by bending a non active band left around the absorber area in the roll bond process. Insulation can finally be added on the back of the module or in the mounting process. Selectivity and colours can be obtained spraying TISS (Thickness Insensitive Spectrally Selective) paints, or using vacuum deposition. Simulations have been carried out to better analyse possible applications on different buildings and drive the prototype realisation. The whole project arises from a constructive cooperation between research institutes and industry of solar collectors and façade systems.
