Building panel solar heat collector - incorporates fluid containing glass pipes with coating of varying translucency

摘要

The building panel component forms a solar heat collector, being heat-insulated. It contains a liquid, gaseous or solid medium for heat-recovery and heated by the sun. It can comprise evacuated glass tubes containing the various absorbent. The latter is separated from the vacuum in the tubes, the heat-transfer medium filling or flowing through it. There can be a coating on the tube inside, and whose transparency or light-absorption capacity is varied thermally or electrically. ADVANTAGE - Combines functions of supporting component, heat insulator, window of variable translucency, and adjustable ventilator.
