Roof structure for collecting solar energy for heat exchange.

摘要

The roof structure 10 comprises a metal cladding layer, preferably made from tiles 12, a support structure 14 and a metal backing layer 16 in contact with the lower portion of cladding layer and mounted to the support structure and including at least one pipe 18 for heat exchange fluid. The backing member is preferably a plate member. The backing layer may be in contact with between 50% and 75% of the cladding layer. The support structure may comprise a series of battens 20 which the backing layer preferably spans between. The backing member may comprise a sheet which defines a number of channels 36 parallel to each other for receiving the pipes. The heat exchange pipe may be connected to heat exchangers located within ground piles or bore holes for heat exchange with the ground.
