Abstract:

A solar energy conversion apparatus having two phases of operation which, in one phase, absorbs thermal energy from sunlight incident on the device, and in a second phase, absorbs energy from air in an attic-type space heated by solar radiation. The two phases may be utilized independently or in concert dependent upon conditions. A solar energy collector is disposed to collect and transfer incident solar energy to a fluid, such as water, flowing through the collector. A heat exchanger is disposed to permit flow of heated air therethrough from an attic-type space in a building, such air having been heated by solar energy incident on the roof of the building. The heat exchanger transfers heat from the air to a fluid, such as water, flowing therethrough. The solar collector and heat exchanger are connected via a plurality of valves and a pump to a water storage tank. Temperature sensors associated with the solar collector, the heat exchanger, and the water storage tank operate a control system which controls the valves and pump to determine the phases of operation of the system.
