Title
(EN) NONIMAGING ASYMMETRIC SHADELESS COLLECTOR
(FR) CAPTEUR SOLAIRE SANS OMBRAGE ASYMÉTRIQUE PAR RÉFLEXION
Abstract
(EN) A solar collector comprising a wide-angle, nonimaging asymmetric optical reflector comprising a reflective film, an absorber assembly positioned within the optical reflector having a transparent tube evacuated to a vacuum or partial vacuum and at least two pipes with fluid flowing through the pipes, the pipes arranged in a flow-through configuration, wherein the solar acceptance angle of the collector is about 40 degrees, allowing for passive (stationary) solar tracking, and where the solar energy collected is transferred to the fluid in the form of heat. The fluid exiting the solar collector is in the range of 100 °C to 250 °C, and the thermal energy of the fluid may be used to generate high-quality steam for solar industrial process heat applications.
(FR) L'invention concerne un capteur solaire comprenant un réflecteur optique asymétrique par réflexion à grand angle comprenant un film réfléchissant, un ensemble absorbeur positionné à l'intérieur du réflecteur optique ayant un tube transparent mis sous vide ou vide partiel et au moins deux conduits avec un fluide s'écoulant à travers les conduits, les conduits étant agencés dans une configuration d'écoulement traversant, l'angle de réception solaire du capteur solaire étant d'environ 40 degrés, permettant une poursuite solaire passive (stationnaire), et l'énergie solaire captée étant transférée au fluide sous la forme de chaleur. Le fluide sortant du capteur solaire est dans la plage de 100 °C à 250 °C et l'énergie thermique du fluide peut être utilisée pour générer de la vapeur de haute qualité pour des applications de chaleur de processus industriels solaires.
