Description

A lightweight prefabricated solar greenhouse shaped phase change heat storage wall

Field of study

The utility model relates to an agricultural building wall structure, which belongs to the technical field of agricultural building structures.

Background technique

Solar greenhouse is a unique type of greenhouse in northern my country. It absorbs heat energy through the wall to achieve heat storage and release, maintains a stable indoor temperature, meets the needs of crop growth, and realizes the efficient production of crops that are off-season in winter. It has excellent performances such as low cost, high energy saving and high efficiency, and has become an important facility to ensure off-season crop production. Clay brick walls and earth walls are the most common thermal insulation and heat storage walls in solar greenhouses. Clay brick walls are expensive and have poor thermal insulation performance. In addition, the production of clay bricks is seriously damaging to the environment, and its application has been restricted by the state. The soil wall has high construction efficiency and good thermal insulation performance, but the soil wall is thicker, consumes a lot of soil, and has certain damage to the cultivated land.

At present, phase change materials are widely used in solar greenhouses, which can absorb excess heat in the greenhouse during the day and release the heat stored during the day at night to ensure that the night temperature of the solar greenhouse is not too low; Therefore, this patent designs a lightweight prefabricated solar greenhouse wall with a shaped phase change heat storage material as the base.
