Description
Technical Field
The utility model relates to a warmhouse booth sunshade technical field specifically is heat pipe-PV/T integration sunshade technology.
Background
Domestic research shows that when the greenhouse film is closed in a sunny day in summer, the temperature in the greenhouse is higher than that outside the greenhouse by more than 20 ℃ and even can reach 30 ℃. In winter, the temperature in the greenhouse can reach more than 40 ℃ within one hour. The foreign scholars Castellano S finds that in high radiation areas in summer, greenhouses are usually exposed to crop withering and even death caused by excessive temperature rise. Transient or sustained high temperature causes morphological anatomical and physiological changes in plants, which affect the growth and development of plantsThe greenhouse is developed, the economic yield of the greenhouse is reduced sharply, and the temperature, the humidity and the illumination intensity in the greenhouse can be effectively adjusted through reasonably shading the sun. Liuchun incense states that temperature and humidity may be one of the reasons for "noon break" in crops. The sun-shading reduces illumination and relieves high-temperature hazard to a certain extent. In addition, CO in the greenhouse2The concentration fluctuates with respiration and photosynthesis of the greenhouse crop. With the photosynthesis of plants in the daytime and the ventilation of the greenhouse being limited, CO in the greenhouse2The concentration tends to drop to a lower level than the outside. Cossu M states that the sun shade most affects solar radiation in the fall (71% on average), followed by the winter (69%), spring (66%) and summer (60%). Research by scholars in China, Wu Xuejiexia and the like finds that the illumination intensity has direct influence on the photosynthesis capability and the disease and insect resistance capability of crops in a greenhouse. Therefore, the control of the change of the illumination intensity in the greenhouse is in an appropriate range, and the improvement of the crop yield and quality is positively promoted.
Traditional sun-shading modes such as sun-shading nets (cloth) and coating reflecting layers are widely applied to remote rural areas in China, and although the modes slow down the environmental temperature in a shed in the daytime to a certain extent, the modes do not realize effective utilization of energy, namely power generation and heat generation. Meanwhile, due to regional characteristics, there are places where there is no power supply. In summer, most farmers only adopt the natural ventilation and sunshade net mode to reduce the temperature in the greenhouse; in winter, the heat dissipation in the greenhouse is slowed down by adding the heat preservation quilt. These measures were clearly somewhat debilitating when in the three-volt day and winter solstice. Partial farmers fix the photovoltaic modules on the surface of the greenhouse to plant yin-loving crops such as mushrooms and effectively convert solar energy into electric energy, but the planting permission of the greenhouse is obviously reduced by the method. The change of the photovoltaic array mode (linear mode and chessboard mode) can effectively improve the illumination distribution in the shed, but the surface temperature of the solar cell panel is increased along with the integral increase of the temperature in the shed, and the power generation efficiency is reduced along with the increase of the temperature. Therefore, the heat pipe-PV/T integrated sun shading device is designed, is applied to a greenhouse for shading sun, effectively reduces the surface temperature of the solar cell panel through the photo-thermal module, improves the power generation efficiency, converts solar energy into heat energy, and realizes effective utilization of energy while shading sun.

The automatic operation management of the sunshade net is realized according to the illumination requirements of different crops, and the automatic operation management system has the characteristics of simplicity in operation and the like. However, there are some disadvantages: the sunlight is shielded only by the automatic contraction of the sunshade net, and the solar energy is not effectively utilized to carry out heat utilization or power generation. The Chinese invention has the patent names: the utility model provides a foldable diffusion glass greenhouse photovoltaic of illumination adjustable, application number is: CN201610918523.3, the invention discloses a folding type diffusion glass greenhouse photovoltaic sunshade curtain with adjustable illumination, which comprises a central system and a sunshade curtain device which are arranged in a greenhouse, and has the characteristics of automatically stretching a photovoltaic film sunshade mechanism and finely adjusting the light transmission area of photovoltaic power generation equipment according to the change of the illumination environment in the greenhouse, but the defects exist, firstly, the system is complex, the manufacturing cost is high, and the generation efficiency of the device is seriously influenced as the surface temperature of a photovoltaic cell rises along with the rise of the indoor temperature.
