Solar heating system with heat accumulator - has three cycle capability matching heat supply and demand of building

摘要

In the first cycle the sun is shining and the building requires heat so the solar captor is connected to the generator with multiple motor driven valves that blows the hot air direct into the building. In the second cycle the sun shines but the building does not require heat so the generator pushes the hot air through the accumulator. In the third cycle the sun is not shining but the buidling requires heat so the generator takes warm air from the accumulator to heat the building.
