Novel south and north dual-shed sunlight greenhouse and operating method

Abstract

The present invention discloses a structure of a novel south and north dual-shed sunlight greenhouse with a middle wall and an operating method. Structurally, the sunlight greenhouse mainly comprises a sunlight greenhouse foundation (1), a south and north shed steel frame prefabricated part connector (2), the middle wall (3), a side wall (4), a cushion working room (5) and a heat exchange control system (6). A sliding door type movable structure of the middle wall (3) plays an important role of regulating the illumination distribution, temperature conditioning and ventilation of a south shed and a north shed. A vertical splitter plate water heat exchange automatic control structure of the heat exchange system (6) is combined with the movable middle wall (3), so that the heat exchange ability of the sunlight greenhouse is improved. The operating method of the sunlight greenhouse mainly comprises the following steps: insulating heat, storing heat, releasing heat and lowering humidity in winter; and ventilating, shading, radiating and cooling in summer, and has the advantages of saving cultivated land, producing all the year, being low in construction cost and the like.

Description

1. Technical field [0001] The patent of the present invention relates to the greenhouse structure and its construction and operation method, especially the structure and construction and operation method of the agricultural solar greenhouse with north and south double sheds. 2. Technical background [0002] The energy-saving solar greenhouse is the agricultural production facility with the largest development area in my country. It plays a vital role in off-season planting and breeding, and in enriching the supply of fresh agricultural products in winter. However, there are still many problems in the structure of the solar greenhouse at present. One of them is that the single shed occupies a large area, and the land utilization rate is only about 30%; the second is that the back wall and gable wall use soil or bricks as building materials, which consumes soil resources; difficulty. People have also researched and constructed north-south sheds, also known as yin and yang sh...

AI Technical Summary

Problems solved by technology

However, the above-mentioned rear wall and the removed light-weight wall have a large volume and area, are difficult to carry and store, and require high maintenance costs. The heat storage capacity of this rear wall is also very poor.

Another big problem is that the solar greenhouses with non-soil back walls have poor heat storage capacity. In the early morning or even cloudy days in winter, the temperature is much lower than that of the solar greenhouses with soil back walls, which makes the production in deep winter affected to a certain extent. Negative Effects

For this reason, someone uses bricks to build a complex heat-absorbing structure, the effect is poor and the construction cost of the earth back wall is high; someone (patent application number: 2012104191403) tries to absorb heat with phase-change materials, the effect is good, but the heat release temperature is high and the construction cost is also high. Too high; someone (patent application number: 2014100400589) sealed air or air driven by a fan is used as a heat storage material, and the heat storage capacity is very poor; someone uses hanging multiple small water bags to store heat with water, which improves the heat storage capacity and low water cost. However, the timing of heat absorption and heat release cannot be controlled and it is easy to leak; someone (application number: 2013107231163) designed a large water bag. Although the heat output increases, it also increases the disadvantages of water bag manufacturing, difficulty in hanging, easy water leakage, and inconvenient use. Some people install solar panels and use glass solar hot water pipes with higher cost; some people (patent application number: 201310237175X) use thin film hot water pipes with lower cost, but the thin film pipes are fragile and difficult to build

Someone (patent application number: 2013100346062) used water as the heat storage medium in a single-shed solar greenhouse and used a solar panel as a light transmission and water flow control component. It is convenient to obtain materials and low in construction costs, but the horizontal use of the solar panel is easy to bend under pressure and the water flow is parallel. flow restriction
