Production intruduction
Multi-span glass greenhouses are an excellent addition to agricultural environments.
The structure's ability to create the perfect environment for plant growth is a marvel of modern technology.
The biggest advantage of multi-span glass greenhouses is that they can accurately control the internal environment of the greenhouse.
Since the greenhouse is equipped with a heating system, cooling system, humidification system and automatic irrigation system,
it can provide a perfect growing environment for any planThis means farmers can grow a variety of different plants in greenhouses, from exotic flowers to high-yielding vegetable crops.
Another significant advantage of a multi-span glass greenhouse is its durability. Unlike traditional wood or plastic greenhouses, the structure of a multi-span glass greenhouse is made of high-quality glass and can withstand harsh weather conditions, including heavy rain, strong winds, and freezing temperatures. Farmers don’t have to worry about their crops being damaged by the weather.
Glass greenhouse ventilation
The purpose of Multi Span Glass Greenhouse ventilation is to remove the waste heat and moisture in the greenhouse, adjust the air composition in the greenhouse, and eliminate harmful gases, so that the ambient temperature, humidity and air conditions in the greenhouse are suitable for plant growth.
1. Natural ventilation: Most of the time, the glass greenhouse relies on natural ventilation to adjust the indoor environment. The structure of large-scale production glass greenhouses is generally a double-slope multi-span greenhouse, and the ventilation method is to set up ventilation windows on the side walls and roof ridges. The total area of ventilation is not less than 15% of the greenhouse area, preferably more than 30%. When the roof ridge window is opened, the window sash should preferably be inclined upward beyond the horizontal plane. When it is 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. When the total area of the ventilating windows is 27% of the indoor floor area, if only the ridge is ventilated, even if the outdoor wind speed reaches 10 km/h, the ideal air exchange rate of 0.75 times per minute will not be achieved; when the ridge ventilating windows and side walls When the ventilation windows are fully opened, the air exchange rate can reach 0.68 times/minute under almost no wind, which is close to the normal recommended air exchange rate of 0.75 times/minute.
2. Although the forced ventilation glass 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. And cooperating with other measures to cool down is a common method 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. The theoretical cooling limit of forced ventilation is that the indoor air temperature is equal to the outdoor air temperature. Because, at this time, the temperature difference between inside and outside the greenhouse is zero, and the ventilation is infinite, which is impossible in practical applications. Due to the physiological reasons of mechanical equipment and plants, the ventilation intensity of the general greenhouse is 0.75 air changes per minute to 1. 5 times, the temperature difference between inside and outside the greenhouse can be controlled within 5℃.
