Zusammenfassung: | The inner chamber (6) filled with filler gas is connected to a volume compensation container formed as a gastight balloon (7). The balloon is made of at least two alternating layers of plastics and metal. It is connected via a connector (5) with the inner chamber of the thermic solar energy collector, to which it is welded, the welding seam being additionally sealed with an adhesive. The balloon is so dimensioned in its size, that with maximum volume expansion of the filler gas there is no excess pressure. The balloon is integrated in the thermic solar energy collector and the filler gas is inert eg. crypton, xenon, argon and carbon dioxide. |
