Development of China 's Daylight Glass Intelligent Greenhouse Construction

    In recent years, the rapid development of facilities and horticulture to solve the northern region of winter fresh vegetable supply problems, the current winter vegetables are more than 90% by the facilities of horticultural production, greatly enriched the people's lives. In China's various forms of horticultural facilities, solar greenhouse as a result of simple equipment, low cost, high production efficiency, in northern China has been widely used.

    Taking the high latitude area in northern China as an example, the solar greenhouse is popular in the process of summer ventilation and winter energy consumption. Relevant data show that China's greenhouse for the year to heat and cooling the energy consumption of the total operating costs of 1/2, excessive energy consumption has become the bottleneck of the further development of the greenhouse. Solar greenhouse energy consumption is a direct factor affecting the greenhouse production efficiency, and improve the greenhouse insulation performance, it directly affects the greenhouse energy consumption. Under normal circumstances, by increasing the lighting area and take a reasonable point of view, to get the maximum solar radiation heat; night with the activities of insulation is covered to strengthen the greenhouse insulation. The energy-saving greenhouse due to the constraints of the lighting side, the former roof can change the space is small, so for the greenhouse greenhouse insulation design, in strengthening the greenhouse roof insulation design, based on the strengthening and improvement of the insulation structure of the envelope is essential The

    The solar greenhouse is an energy-efficient building that makes full use of solar energy, and the walls have a direct impact on the greenhouse thermal environment. Not only to make the wall with load-bearing and insulation function, but also has a good thermal insulation and thermal storage function, during the day to a lot of heat storage, the night to an endless stream to the indoor heat. Therefore, it is necessary to study the thermal insulation performance, structure and material properties of solar greenhouse wall, to find the combination of wall material and wall combination, to improve the thermal insulation effect of greenhouse, to reduce the winter heating and summer Cooling the loss, and thus improve production efficiency.
