Greenhouse-type heliogreenhouse with solar energy heat collection and storage system and application of greenhouse-type heliogreenhouse

Abstract

The invention discloses a greenhouse-type heliogreenhouse with a solar energy heat collection and storage system and application of the greenhouse-type heliogreenhouse, and belongs to the technical field of solar energy utilization in agricultural engineering. The solar energy heat collection and storage system and a stereoscopic cultivation system are installed in the greenhouse-type heliogreenhouse; regarding the solar energy heat collection and storage system, a PE pipe fixed to a greenhouse framework is used as a heat collection and storage system, water serves as a heat storage medium in the pipe, and in the day, solar energy is absorbed by using water to be recycled to conduct heat exchanging in the PE pipe on the framework and stored in a heat-preservation impounding reservoir; the stereoscopic cultivation system serves as a cultivation frame to be used for producing vegetable crops, and also serves as the heat collection and storage system to store solar heat energy in the day in the greenhouse. The greenhouse-type heliogreenhouse is easy to maintain, and is energy-saving-type development tendency of the heliogreenhouse. The greenhouse-type heliogreenhouse can effectively reduce heat loss, increase the yield of fruits and vegetables in the heliogreenhouse and improve the quality of the fruits and vegetables. The greenhouse-type heliogreenhouse is simple in structure, low in cost, convenient to operate, and good in running effect. The greenhouse-type heliogreenhouse has the advantages of saving energy and being practical.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization in agricultural engineering, in particular to a greenhouse-type solar greenhouse with a solar energy collection and heat storage system and its application. Background technique [0002] The solar greenhouse is a unique cultivation facility in my country. It can be used for the overwintering production of fruits, vegetables and flowers without heating or a small amount of heating. After decades of development, the solar greenhouse has been widely used because of its good heat storage and heat preservation performance. The problems existing in the use of solar greenhouses have also become increasingly prominent, and the problem of poor temperature and humidity environment regulation is the most serious. Since the solar greenhouse only relies on the back wall for passive heat storage, the heat storage capacity and heat storage are limited. In the case of extremely low temperature in...

Problems solved by technology

[0004] In addition, the inherent defects of the main structure of the solar greenhouse greatly reduce the effective use of land

Compared with large-scale greenhouses, the effective land utilization rate of solar greenhouses is mainly restricted by the following three factors: ① small-span structure is adopted, so the marginal effect is relatively increased, resulting in a significant decrease in land effective area ratio; ② the phenomenon of land occupation by the back wall of the greenhouse is prominent , First, the wall itself has an obvious land occupation effect, which is more prominent when the wall is thicker; second, the marginal effect formed by the wall limits the effective use of the land near the wall; ③ in the greenhouse group with a certain scale , in order to avoid the mutual shading effect between the greenhouses, a fairly wide open space must be reserved between the front and rear greenhouses, and the phenomenon of land waste is also obvious
