Ventilation form of glass smart greenhouse

The glass smart greenhouse is what we often hear or see. With the development of modern agricultural technology, our agricultural technology has been compared. The glass smart greenhouse is a relatively successful application. Whether it is in vegetable planting or flower garden crop planting, the application is relatively accurate and successful. The emergence of off-season vegetables is the use of glass smart greenhouse technology. Next, through this article, I will give you a specific introduction to the ventilation form of the glass smart greenhouse.

1. Natural ventilation

The glass smart greenhouse relies on natural ventilation to adjust the indoor environment most of the time. The structure of large-scale productive glass intelligent greenhouses is generally a double-slope multi-span greenhouse, and the ventilation form is to set up ventilation windows on the side walls and roof ridges. The total ventilated area is not less than 15% of the greenhouse area and greater than 30%. When the roof ridge window is opened, the window sash can be tilted upward across the horizontal plane. When fully opened, it forms an angle of 100 with the horizontal plane to obtain a good ventilation effect. The amount of natural ventilation is related to wind speed, wind direction, position of ventilating window, area of ventilating window, and temperature difference between inside and outside the greenhouse.

2. Forced ventilation

Although the glass smart greenhouse relies on natural ventilation to adjust the environment most of the time, when the temperature in summer is high, especially when the outdoor temperature * exceeds 33 ℃ in hot weather, it is difficult to meet the cooling requirements of the greenhouse by natural ventilation alone, use forced ventilation and cooperate with it. Other measures to cool down are commonly used methods in production. Forced ventilation is the use of fans to convert electrical or other mechanical energy into wind energy, forcing air to flow to ventilate the greenhouse and achieve a cooling effect.
