Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to a ventilation structure for glass greenhouses used in facility agriculture. Background Technology

[0002] Greenhouses are widely used for the cultivation or seedling raising of vegetables, flowers, trees and other plants because they have the advantages of regulating environmental conditions such as temperature, humidity and light, and can withstand natural disasters such as wind, rain, hail and frost, thus meeting the diverse needs of the market.

[0003] Greenhouses mainly include plastic greenhouses and glass greenhouses. Except for their lower cost, plastic greenhouses are far inferior to glass greenhouses in other aspects. The smooth surface of glass results in low light scattering and more uniform light distribution inside, reducing uneven growth of crops caused by light differences.

[0004] Glass greenhouses are further divided into ordinary glass greenhouses and double-glazed greenhouses. The heat transfer coefficient of double-glazed glass is as low as 2.0-3.0 W / (㎡·K), which is lower than the heat transfer coefficient of single-glazed glass of 5.0 W / (㎡·K). In winter, it can reduce heat loss and reduce heating energy consumption. In summer, with the help of external shading systems (shading rate of 70%-80%) and ventilation equipment, the indoor temperature can be effectively controlled and high temperature stress can be avoided.

[0005] Traditional glass greenhouse ventilation structures mainly rely on a combination of side wall ventilation windows and top ventilation windows, but they have problems such as limited ventilation range and significant influence from external wind direction, which can easily lead to uneven airflow distribution inside the greenhouse and localized stuffiness or cold damage.

[0015] Compared with the closest existing technology, the beneficial effects of this utility model are as follows:

[0016] 1. The first ventilation group of this utility model provides horizontal air supply to cover the central horizontal area of ​​the greenhouse, the second ventilation group provides vertical air supply to drive air exchange between the upper and lower layers, and the third ventilation group provides lateral air supply to enhance ventilation in the edge area.
