So as to provide good indoor work when it is cold at night in winter, the closure of the sunshade can effectively prevent the loss of heat in the greenhouse and play the role of energy saving and heat preservation. According to the planting of crops. To ensure the reasonable function of sunlight, the name shading rate, energy saving rate, standard width, aluminum foil, inner shade, heat preservation type, aluminum foil inner shade, air permeable type, external shade, longevity, external shade, folding, folding,%% window system, gear and rack continuous window opening system is a window starting form often used in large multi-span greenhouse. The system runs smoothly, safely and reliably. In this system, the deceleration motor drives the gear to rotate through the drive shaft, the gear meshes the rack to make it move back and forth in a straight line, and the end of the rack is connected to the support of the ventilation window. So as to realize the opening and closing of the ventilation window. Choose the outer shading screen with different shading rates, which can make the sunlight diffuse in the greenhouse.
A part of the diaphragm is coated with a transparent reflective film, and the image and data on the dashboard transmitted from the projector can be displayed on the diaphragm as needed, which is convenient for the driver to observe, and the driver does not need to look down at the instrument when driving. The image shows that if the intelligent glass cooperates with the infrared image display system, the driver can see clearly the objects around the 2km in front of him on a foggy day. The photoelectric sunshade roof glass can automatically absorb, accumulate and use solar energy to drive the car fan when the car is driving or parking, and it can also continuously recharge the car battery.
The summer sun is fierce, many private cars are parked in the sun, as long as 10 minutes, the steering wheel, seats will be particularly hot, and the car temperature rises sharply. Today we recommend a good thing, the ingenious car front windshield sunshade umbrella, which can improve this problem. This umbrella can insulate heat and block the sun, so you can stop in the sun with peace of mind. The sunshade itself can be taken in and put into the glove box. When unfolded, the size is so large that both the car and the SUV can cover the entire front windshield. In addition, now, this front windshield sunshade is on sale in JD.com, and the current price is 34.9 yuan.
Raise the level of mechanized production and liberate labor productivity. First of all, from the environmental control system of multi-span greenhouse, electric sunshade, electric film (window opening) ventilation, electric thermal insulation quilt, electric fan water curtain cooling have been realized, and the environmental control ability of greenhouse is more stable and reasonable. work efficiency is higher, do not need manual operation, just press the switch of the distribution cabinet. Looking at the agricultural production in some backward areas ten years ago and even now, this is a great progress for facility agriculture in our country. Secondly, the interior of our multi-span greenhouse can be equipped with mechanized automatic sprinkler irrigation, integrated water and fertilizer machine, automatic seeder, and even Internet of things control software are now very common systems. greatly improve the production efficiency and achieve precision irrigation and fertilization, water-saving and fertilizer-saving, soilless cultivation and other protection of soil from pollution.
The key points of the building ecological energy strategy and design for the renovation of the new German parliament building lie in the technical application and energy strategy of ventilation and lighting. After the reconstruction, the output of carbon dioxide in the building has been reduced by nearly 94%. Through the set path, the air is filtered and cooled into the building, and then the hot air and waste gas are discharged upward by the two-story dome through the building technology; natural lighting is realized by an inverted cone light reflector and a 360-degree tongue-shaped sunshade device, which is equipped with an air pipe and a heat converter, and the tongue-shaped device can rotate according to the change of the solar height angle during the day. The energy strategy adopted in the reconstruction of the building is more radical, including not only the use of solar power, but also the use of renewable “biodiesel” generators to generate electricity, coupled with the storage and recycling of geothermal heat.
The concentrated display area of the curtain wall technology is also rich in bright spots, in which the tower curtain wall adopts the external sunshade technology, and the sunshade board is designed at the angle of the west sun on the outside of the curtain wall, which can prevent the solar radiation heat from entering the room from the glass window in summer and prevent the indoor heat from escaping from the glass window in winter, saving about 10% of the building heating energy consumption.
