Air-conditioned buildings rely on refrigerators to move the indoor heat load to the outside in summer. Obviously, if the indoor heat load is reduced, the running time of the refrigerator will be reduced, and the energy consumption of the cooling tower system will be reduced. The indoor heat load comes from two aspects, one is the heat exchange caused by the indoor and outdoor temperature difference, and the other is the heat load caused by indoor lighting and equipment. Therefore, sunshade, airtight, thermal insulation and other methods can be used to reduce indoor heat load and achieve energy saving. 1, reduce indoor heat load (1) sunshade to reduce direct sunlight radiation roof, wall, window and through the window to enter the room, you can use eaves, sunshade panels (awnings), coated glass, etc.; reduce the heat radiation of the external walls and roofs, you can use light-colored exterior wall finishes to set the insulation layer on the outside of the external walls and roofs, or overhead roofs.
At present, spray-free plastic has been successfully used in automotive parts such as side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts. Bioplastics bioplastics are produced under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Commonly used plastics are generally synthesized from petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics are prepared into automobile interior parts with large amount of VOCs volatilization in the pulley because of the use of renewable raw materials with low toxicity and low harm. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
Two days ago, Sun Li also posted a photo of her sister modeling another handbag made by her mother. In the photo, many girls wear sunglasses and sunshade hats, a white shirt dress and a bag made by their mother, dressed in a fresh and stylish literary style.
Moreover, the hot weather will cause damage not only to the paint surface, but also to the car interior and dashboard. Therefore, car owners are advised to install sunshade curtains on their cars in summer. Has a very good thermal insulation effect, effectively isolate the sun, ultraviolet rays, but also can block the light and protect privacy.
3. The exterior ornaments of the car body mainly refer to decorative strips, wheel covers, signs and embossed words, etc., and accessories such as radiator masks, bumpers, lamps and rearview mirrors also have obvious decoration. 4. Car interior decorations include dashboards, ceilings, sidewalls, seats and other surface decorations, as well as curtains and carpets. Surface finishing materials such as natural fiber or synthetic fiber textiles, artificial leather or multilayer composite materials, skin foam and so on are widely used in cars. On the bus, there are a large number of decoration materials such as fibreboard, cardboard, engineering plastic board, aluminum board, pattern rubber board and composite decoration board. 5, body accessories door locks, door hinges, glass lifts, various seals, windscreen wipers, windwindow scrubber, sunshade, rearview mirror, handle, cigarette lighter and ash box, etc. Radio recorders and pole antennas are often installed in modern cars.

Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Jilin solar energy greenhouse needs the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied.
