Solar greenhouse with heat storage and dehumidification wall and functions of self-heating and convective circulation

A solar greenhouse with a heat storage and dehumidification wall and functions of self-heating and convective circulation comprises a north rear wall, a north rear roof (12), gable walls at the two ends and a lighting roof supported by an arch-shaped roof truss (6). The north rear wall is of a hollow composite structure and is composed of an internal wall body (2), an external wall body (4), a wall crown (14) and a hollow part (5), a greenhouse inner portion (10) and the hollow part (5) of the wall are communicated through an upper horizontal vent hole (1) and a lower horizontal vent hole (3) which are respectively arranged in the upper portion and the lower portion of the internal wall body (2) in the length direction of the greenhouse. According to the solar greenhouse, through the natural force function of the air temperature difference and gravity difference in the greenhouse and the hollow part of the wall, air enters the wall for heat exchange, and under the condition of not consuming electric power and other energy, the solar utilization rate of the solar greenhouse and the regulation and control capacity on temperature and humidity in the greenhouse are effectively improved.
