Solar greenhouse wall of composite structure

Abstract

The invention discloses a solar greenhouse wall of a composite structure. The solar greenhouse wall of the composite structure comprises an inner wall body, a ring beam, an outer wall body, a heat insulation layer, a ground and an air layer structure. Ventilators are arranged on the inner wall body, the heat insulation layer is mounted on the outer side of the outer wall body, and a connecting brick wall is built in the air layer along the wall body extension direction. The solar greenhouse wall of the composite structure is reasonable in structural design, easy to build and construct, low in construction cost, high in wall body stability, excellent in heat storage performance and long in service life and can be widely applied to the fields of agriculture and livestock husbandry.

Description

technical field [0001] The invention belongs to the field of greenhouses, and in particular relates to a solar greenhouse wall with a composite structure. Background technique [0002] The solar greenhouse wall has the functions of load bearing, heat collection, heat storage and heat preservation. It is an important heat source for the greenhouse at night in winter. The stronger its ability to store solar energy during the day, the more heat it provides to the greenhouse at night. Studies have shown that the heat storage and heat preservation performance of the solar greenhouse composite structure wall is better than that of the single structure wall. However, since traditional solar greenhouse wall materials are usually sensible heat storage materials (such as clay brick walls and earth walls), only sensible heat storage limits the utilization of solar energy by greenhouse walls. In current agricultural production, the protection facilities with the largest area are solar ...

AI Technical Summary

Problems solved by technology

However, because the wall materials of traditional solar greenhouses are usually sensible heat storage materials (such as clay brick walls and earth walls), the use of solar energy by the greenhouse walls is limited only through sensible heat storage.

In current agricultural production, the protection facilities with the largest area are solar greenhouses and large sheds. Solar greenhouses have the best protection conditions and can carry out agricultural production throughout the year. Therefore, in most parts of northern my country, solar greenhouses are the main way to cultivate vegetables in winter , but at the same time, due to technical defects and excessive input costs, many low-cost greenhouses cannot maintain a suitable temperature, and often make plants unable to adapt to low temperatures, resulting in large-scale production reduction or even failure.
