Building facade solar heating system - uses solar cells to operate liq. circulating pumps for internal and external heat exchangers

摘要

The solar heating system incorporated with the facade of a building, has heat collectors forming a grid on the wall, for heating a liquid which is circulated around the system, as in the main patent. On the outside of the collectors, are solar cells (8) which have connecting leads (9) passing inside, connected to pumps (12) which control the flow of the liquid. The cells are mounted close to or upon the heat exchanger portions (14) on the outside of the collectors. The pumps control the flow through the internal heat exchanger portions (16). The solar cells are enclosed by a glass panel (7) on the facade.
