Abstract
An integrated solar thermal system for a building roof is provided. The system utilizes a plurality of fin pipes to collect solar energy as heat, and to transfer this heat to a working fluid conveyed in a parallel flow through the fin pipes. The heated working fluid is then used for productive energy conversion.
Claims20
A solar heat absorbing fin pipe assembly for use as a roof comprising:
- a plurality of fin pipes, each fin pipe comprising a pipe defining a flow channel, and two fins extending away from a top of the pipe such that the pipe extends downward from the fins, the fins integrally formed with the pipe and together forming a top face configured to receive a solar radiation, wherein the two fins are formed of an unglazed metal;
- wherein each fin pipe is arranged to be parallel to an adjacent fin pipe;
- and
- a quantity of piping attached to the fin pipe assembly, the piping comprising an inlet pipe, an inlet header splitting into a plurality of parallel inlet flows, each inlet flow connecting to one of the flow channels of the plurality of fin pipes, an outlet header connecting outlet flows from each of the flow channels, and an outlet piping.
