Solar energy storage ventilated heating system

The invention discloses a solar energy storage, ventilation and heating system, which comprises a heat storage wall composed of a heat-insulation layer, a heat storage layer and an aluminum plate painted with black paint, a heat storage ventilation channel or a combination thereof, which are sequentially arranged on the outer side of the external wall of a building; a transparent cover plate arranged on the outer side of the heat storage wall or the heat storage ventilation channel; an air sandwich between the transparent cover plate and the heat storage wall; and an upper vent and a lower vent having valves and arranged on the transparent cover plate and the heat storage wall. The solar energy storage, ventilation and heating system can achieve intermittent ventilation and heating without consuming non-renewable energy by using the special heat absorption and release functions of a phase-change heat storage material and by controlling the valves of the vents. The system has the advantages of energy conservation, environmental protection, simple control and handsome structure, and can be widely used for common residential buildings and public buildings.
