Delivery time: 8-12 business days (International)
Dans le contexte nergtique et environnemental actuel, il devient essentiel de dvelopper des technologies de production dnergie propre et moins coteuse. Parmi les solutions mettre en uvre dans le domaine de rfrigration solaire, les systmes adsorption, bnins visvis de l'environnement, sont parfaitement adapts aux rgions ensoleilles o la production de froid est vitale. Le prsent ouvrage constitue un document de recherche scientifique qui vise contribuer au dveloppement de la technologie de rfrigration solaire adsorption ; il propose ltude de deux systmes originaux : le premier est intermittent tandis que le deuxime fonctionne en cycle continu. Il prsente galement les principales notions et thories du phnomne dadsorption ainsi quun tat de lart sur les caloducs et les capteurs destins la conversion thermique de lnergie solaire. Cet ouvrage sadresse un large public (chercheurs, industriels, ingnieurs, techniciens, etc.) dsirant se pencher sur la question de rfrigration solaire. Esprons que le lecteur y trouvera quelques lments de rflexion profitables et des ides originales.
