Now most cars are equipped with CD equipment, autumn affect the normal work of the car audio is mainly high and mild, because the car audio is more installed in the upper part of the dashboard, in order to avoid sunlight, the use of sunshade effect, if the doors and windows seal should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit burning host. Car consignment company information report according to Deutsche Welle, the market is becoming more and more important to the German automobile industry. Audi, BMW, Mercedes-Benz and other German cars are very popular with motorists. It is even said that Germany can get out of the economic crisis faster mainly due to the rapid development of the car market and the good reputation of the German car MadeinGermany. In addition to the automobile manufacturing industry, including the spare parts industry.

This trailer adopts European-style foamed passenger door with beautiful appearance and better thermal insulation and sound insulation performance. The door is equipped with insect-proof gauze curtain and privacy curtain to effectively avoid mosquito bites and enjoy private space. The door is equipped with trash can and portable step stool, which is made of European plastic to facilitate passengers to get on and off the bus. Overhead skylight, large size and lighting, equipped with anti-mosquito gauze curtain and privacy curtain to meet the car lighting and air circulation. External inflatable 3-meter sunshade, sunshade guide rail using full-car aluminum alloy edge card slot, lightweight and durable, effectively expand outdoor activity space, avoid ultraviolet interference, play more enjoyable. With storage, large space can be used for travel luggage and outdoor supplies.

Exposed to sunlight during the day, the largest heating area is the film coverage, and the largest heat dissipation at night is also the film coverage. Because the film coverage area is larger, so the thermal insulation effect of the film coverage is very important. Therefore, it is necessary to do a good job in the protection of film coverage. The shading system at the top of the greenhouse is divided into external shading, internal shading and internal heat preservation system, which are controlled by computer. The weather station system on the outside of the shed might as well monitor the wind direction and temperature at any time. The configuration of the greenhouse sunshade system is beneficial to the accumulation of reducing heat in the greenhouse, and the comprehensive temperature of crops under the sunshade is actually lower than that directly reflected by the open sun.

9. Blanket: A lightweight and versatile blanket serves multiple purposes. It can be used for warmth, as a makeshift sunshade, or even as a clean surface when needed.

Even more impressive is the compact interior. the recycled cork-a material that absorbs carbon dioxide during production-has been used on the tops of dashboards, sunshades and doors-as an alternative to traditional foam materials. all other decorative panels were omitted and the exposed basic metal structure was painted blue.

In May, take advantage of the holiday, choose a lawn with three or five friends, under the comfortable sunshade tent, you can put on a red and white plaid picnic mat and bamboo rattan snack basket, or you can sit at the online celebrity ins omelet table, eat barbecue, play vulgar wine table games, and come to Yunlan Bay to find the beautiful spring light missed this year in the sunshine, flowers, food and laughter.

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.

For example, a sunshade structure made of snow fence material can provide a shading rate of about 30-50%. But this kind of shadow can greatly reduce the heat load in extreme conditions. Another advantage of the snowboard material is the small wind and snow load, which reduces the cost of the structure. The demand for shadows also depends on the upper limit and duration of the summer temperature of the fattening area. Shading can obviously improve the production performance in the areas above 29.4 °C and 700h/ years. In the area where the sunshine is 500-700 hours a year, the influence is diverse, and the influence is different in different years. The factors to be considered in shadow design include the area of shadow, the position of shadow, the direction of shadow structure and the type of material to be used.

So we should adopt the form of deep ploughing. Only in this way can we compare the photosynthesis between plants. It can do a good job of topdressing and the dilution between fertilizers in the later stage. Why should sunshade net be covered in the construction of greenhouse? Prevent rain and release hail. Can reduce the impact of rainstorm and hail, its damage to crops in the shed, cooling in summer and autumn, sunshade net can effectively block the sun and reduce the temperature in the shed. Avoid the harm of strong light and high temperature to crops. (3) moisturizing and drought resistance, the communication speed between the air and the outside world becomes slower, and the relative humidity in the shed will become larger. (4) keep warm and prevent frost. Covering the sunshade net in winter can protect the ground temperature and frost, and do a good job in the overall heat preservation of the glass greenhouse. 1 where conditions permit. The construction of semi-underground border surface can be used for the temperature of the soil in the glass greenhouse. Play a good role of soil heat preservation;

6. the valid period of the beach epidemic prevention regulations is extended to July 31, including: statistics shall be carried out at the entrance of the beach, with a maximum of 40 people per 1,000 square meters; customers in line must keep at least a distance of 1.5 meters; sunshades are at least 4 meters apart. Except for families with children, a maximum of two recliners can share a sunshade; swimmers must bring their own towels on the recliner. Team sports with physical contact are prohibited. If crowds gather in the beach bar, it will be closed.

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 glass greenhouse in Tibet needs the cooperation of a variety of equipment, with the increasing temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system, window opener, fan, wet curtain and other equipment need to be applied.
