Abstract:
A partir de una placa solar o fotovoltaica (3), con sus correspondientes conexiones PNT al circuito que alimenta eléctricamente, a la cara posterior de dicha placa solar y con la colaboración de separadores (se), se fija un captador termodinámico a base de una chapa metálica (1), con una embutición (C) participante en un serpentín para la circulación de gas, serpentín que se cierra mediante una segunda chapa metálica (2), lisa, convenientemente fijada a la chapa (1). De esta manera además de captar la energía lumínica solar para su transformación en energía eléctrica, se aprovecha el calor o frío ambiental, para calentar o refrigerar un fluido de transmisión térmica hacia un intercambiador.
Abstract:
Ce double vitrage peut comporter entre les deux plaques de verre , des lamelles (95) (figure 13a) de store vénitien, relevables ou non et inclinables dont la surface est noire. La lamelle est en métal recouvert d'un composite noir à base d' E.T.F.E (Ethylène Tétrafluor Ethylène) ou l'un de ses dérivés ou un produit équivalent, ou autre revêtement absorbant le rayonnement solaire et peu adhérent. Ce double vitrage peut être isolé de l'extérieur par une lame d'air (13) d'environ 28 mm, en rajoutant une troisième plaque de verre vers l'extérieur(15) De même une lame d'air située à l'arrière (101) l'isole de l'intérieur du local. La plaques arrière(102 peut soit être une plaque de verre fixe, soit une plaque de verre mobile(comme une porte coulissante), soit encore un film transparent de polycarbonates ou E.T.F.E. enroulable. Si cette plaque (102) est fermée, il y aura plus de production d'eau chaude et le local est isolé de la chaleur du soleil, ce qui est utile en été. Si cette plaque (102) est rétractée, le local profite de la chaleur du soleil et se réchauffe ce qui peut être utile en hiver. Les lamelles pouvant être fermées complètement, permettent d'occulter la vue de l'extérieur du local.
