Rear-wall heat-storage and heat-release integrated solar greenhouse

Abstract

The invention relates to the technical field of agricultural engineering, and discloses a rear-wall heat-storage and heat-release integrated solar greenhouse. The rear-wall heat-storage and heat-release integrated solar greenhouse comprises a rear wall and side walls which form a greenhouse; the interior of the greenhouse is provided with a heat-storing assembly and a transparent rolling curtain assembly. The rear-wall heat-storage and heat-release integrated solar greenhouse provided by the invention has the following advantages: the rear wall adopts a structure of a stainless steel pipe framework and a solar heat-collecting panel arranged on the framework, so the heat-storage and heat-release integrated design of the rear wall is realized; meanwhile, through arrangement of the transparent rolling curtain assembly, when the solar heat-collecting panel of the rear wall starts operation during the day, a transparent film is completely covered at one side of the inner surface of the solar heat-collecting panel, and a cavity is formed at the front of the solar heat-collecting panel, so the heat loss of the heat-collecting panel is isolated, and the heat energy storage amount of circulating water is improved; and when the heat is needed to be released at night, the transparent film is opened, and the circulating water continues circulation in the stainless steel framework, so heatrelease is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural engineering, in particular to a solar greenhouse with a rear wall integrating heat storage and release. Background technique [0002] In the solar greenhouse, the indoor ambient temperature is low at night in winter, which seriously affects the quality and output of vegetables and fruits in the greenhouse. Solar greenhouses have always used the passive heat storage method of the wall to increase the temperature at night in winter. Due to the limitation of the heat capacity of the wall material, the temperature of the greenhouse in winter often cannot meet the needs of plants. In some places, the thickness of the wall is even blindly increased. The waste of resources is serious, and the warming effect is extremely limited. Most of the other existing solutions are heating by burning traditional energy sources (coal, oil, natural gas, etc.). Such heating devices pollute the environment and are ...
