Glass greenhouse is a kind of greenhouse, mainly glass as a lighting material greenhouse. The main purpose of glass greenhouse ventilation is to eliminate the water in the greenhouse and the waste heat in the greenhouse, to eliminate harmful gases to the human body, and to better regulate the air composition in the greenhouse, so that the air and humidity in the greenhouse are more suitable for plant growth. Glass greenhouse ventilation generally takes two forms:

Natural ventilation
Glass greenhouse mostly depends on natural ventilation to adjust the indoor environment. The structure form of large productive glass greenhouse is generally double slope continuous greenhouse, and ventilation form is to set ventilation window on side wall and roof. Its total ventilation area is not less than 15% of the greenhouse area, more than 30. When the roofwindow is opened, the window sash can be tilted above the horizontal direction, when all open and horizontal
The surface forms 100 angles, then can obtain the good ventilation effect. The ventilation volume of natural ventilation is related to wind speed, wind direction, ventilation window position, ventilation window area and temperature difference inside and outside greenhouse.

Forced ventilation
Although glass greenhouses rely mostly on natural ventilation to regulate the environment, when the summer temperature is high, especially when the outdoor temperature exceeds 33℃ or more, it is difficult to meet the cooling requirements of greenhouses by natural ventilation alone. Forced ventilation and other measures are commonly used in production. Forced ventilation is the use of fans to convert electric energy or other mechanical energy into wind energy, forced air flow to carry out greenhouse ventilation and achieve cooling effect.
our main business is processing intelligent greenhouse, ecological restaurant greenhouse, continuous greenhouse, glass greenhouse, thin film arched greenhouse, PC sun panel greenhouse, horticultural greenhouse, modern flower market greenhouse, intelligent flower greenhouse, steel structure flower exhibition hall greenhouse, aquaculture greenhouse and various greenhouse greenhouses, etc. we can also produce all kinds of ecological restaurant types with high roof, large span and large open space. the appearance is beautiful, the internal vision is wide and spacious and bright.
