to reduce solar radiation. The calculation of sunshade is very important



Conclusion: after reading this article, I believe you should already know something about the black dots of different sizes of these matrix designs on the edge of the front windshield. Such a black edge design not only improves the beautification effect of your car, but also plays a sunshade role for you when you are driving. When the sun is in direct light, it protects the windshield burst very well, such a small black dot, but it hides a lot of mystery.

First, the sunshade curtain of the car is exposed to sunlight in three dog days, and people sweat immediately in less than a minute in the sun. similarly, if you love a car for a long time, not only the fashion of people going in is as uncomfortable as a sauna, but it does a lot of harm to the car. And under the exposure of the sun, the temperature inside the car with closed windows will rise sharply to 50 or 60 degrees Celsius or even higher, and the high temperature will damage the dashboard and leather seats.

To make a simple list, the Tianyi co-creation version has the following configurations: yacht electronic shift lever + steering wheel shift dial, electric tail door with foot induction opening and closing, 360-degree panoramic parking image, standard four-probe reversing radar, 12.3-inch full liquid crystal color digital dashboard, integral panoramic skylight (with electric sunshade), rain sensor intelligent front wiper.

4. Greenhouse management: first, we should do a good job of anti-freezing. Freezable flowers can be equipped with an inner film in the greenhouse to form a two-layer film for heat preservation, and heating can also be carried out in the greenhouse if possible. Second, it is necessary to do a good job in strengthening the greenhouse. On snowy days, when there is snow in the greenhouse, we should remove the snow from the roof in time, increase the light transmission, prevent the greenhouse from being crushed by the snow, and reduce the freezing low temperature after the snow melts. When clearing the snow, you should avoid piercing the greenhouse film and transport the snow out of the nursery. The greenhouse with collapse and collapse deformation should be strengthened and repaired immediately, and if it cannot be repaired, the plants in the shed should be transferred in time, or covered with film, grass curtain or sunshade net to improve the heat preservation effect.

From the point of view of yield, it is mainly the anti-freezing damage of low temperature in winter. This technique is relatively easy for greenhouse loquat. For Jiangsu and Zhejiang areas, it is necessary to prepare double-film covering materials after entering December, and double-film mulching should be carried out when the cold air comes or the lowest temperature drops below 5 degrees Celsius. When the lowest temperature affected by cold air is below 0 degrees, further heat preservation work needs to be done on the basis of double film. The main measures are as follows: first, sprinkler irrigation should be carried out during the day to increase soil water content and humidity to increase heat capacity. the fog produced by the cooling of high humid air can slow down the temperature drop; second, build a sunshade net on the loquat tree. Third, the heating treatment is carried out in the shed, and the heating time is from the second half of the night to the morning. The prevention index of frost injury during flowering is to keep the temperature in the shed above 0 degrees.

In summer, the indoor air conditioning load mainly comes from the solar radiation heat of the windows entering the room, so taking effective shading measures is an effective way to reduce solar radiation. The calculation of sunshade is very important in the calculation of load and energy saving of air-conditioned buildings. Building shading methods can be divided into three categories: external shading, characteristic glass and internal shading. External shading can be constructed by sexual building shading, such as sunshade panels, sunshade panels, eaves, etc., or it can be movable and adjustable, such as louvers, movable baffles, rolling curtains and so on. These sunshade structures are commonly used in traditional buildings. Characteristic glass is the use of modern glass coating technology, so that the window glass can choose the incident sunlight, play as much as possible to introduce visible light, while reducing infrared light into the room.

More impressive than the appearance are the reborn carriages, where recycled cork, a material that absorbs carbon dioxide during production, has been used on top of dashboards, sunshades and doors as an alternative to traditional styrofoam. All other decorative panels are omitted, exposing the basic metal structure, which is painted blue here.

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.

Interior materials refer to single or laminated composite organic materials used for cab and passenger cabin parts, including cushions, seat backs, seat covers, seat belts, headrests, handrails, movable folding roofs. All decorative linings (including door inner panel, front panel, side panel, rear panel, roof lining, etc.), instrument panels, grocery boxes, indoor shelf panels (including rear windowsill panels), curtains, floor coverings, sunshade panels, wheel cover coverings, engine hood coverings and packing, cushioning devices used to absorb collision energy during a collision.
