Controllable regenerative solar air collector combined with building

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of solar photothermal utilization and building integration, and in particular relates to a controllable thermal storage solar air heat collector combined with buildings. Background technique [0002] Solar thermal utilization technology is currently the most mature technology and the most widely used solar energy utilization technology in the market. In terms of solar air collectors, flat-plate collectors are one of the best choices for combining with buildings because of their simple structure and reliable operation. The setting of the flat-plate air collector can solve the problem of indoor heating during the day, but because the collector directly converts solar energy into hot air and transmits it indoors, and the heat supply of solar energy is intermittent and unstable, so the indoor temperature fluctuates too much , Even at night or on cloudy days, the heating function of the collector fails. Therefo...
