The invention discloses a controllable regenerative
solar air collector combined with a building. The controllable regenerative
solar air collector comprises a tile-shaped cover plate, a
flat glass cover plate, a collecting plate,
copper pipes, an air runner, an air inlet, an air outlet, a water inlet, a water outlet, a tee valve, a circulating water pump and a water tank, an air interlayer is formed between the
glass cover plate and the collecting plate, the air inlet and the air outlet are formed in the water tank below the bottom of the collecting plate in the height direction respectively to form the air runner, one row of
copper pipes and fins are arranged in the air runner, one row of
copper pipes and fins are also arranged at the bottom of the collecting plate, and two copper pipes are communicated with the water tank through the circulating water pump, the air inlet, the air outlet and the tee valve. Hot air is prepared as needed by controlling opening and closing of the air inlet, the air outlet, the water inlet and the water outlet and switching of the circulating water pump, the problem of difference between
irradiation intensity and thermal requirement time is solved, and solar photo-thermal sufficient use is realized. The controllable regenerative
solar air collector has the advantages that the collector is simple to manufacture and stable in running, and integration degree between the collector and the building is high. The collector has a wide application prospect and a popularization value in integral application of the solar building.
