Experts say that water shading should be used in the south and north directions of buildings; vertical shading should be used in northeast, north and northwest directions; comprehensive shading should be used in southeast and southwest directions; and baffle shading should be adopted in east and west directions. In architectural design, it is appropriate to combine exterior corridors, balconies and eaves to achieve sunshade in hot summer and warm winter areas, with long summer heat and strong solar radiation

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.

As we all know, the main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, to a certain extent, it can reduce the burning inside the car, and prevent leather seats and dashboards from being damaged by ultraviolet rays. But there are still some car owners who doubt whether sunshade really has the above effect.

The interior decoration and decoration building materials of this project are strictly selected as environmental protection building materials; the natural lighting of the interior is improved by using the daylighting atrium and sunken square, the outer glass curtain wall can be opened, and the interior gets good natural ventilation in the transition season. Horizontal fixed external sunshade and indoor high reflection activity curtains to reduce indoor solar radiation heat gain in summer. Centralized fresh air system is set up in each layer, and CO2 concentration sensor is set in densely populated area. Fresh air volume can be adjusted in linkage. The underground garage is equipped with a CO concentration sensor and is linked with the exhaust equipment.

In addition to personalized needs, the new car also accurately locates the pain points for women, adding a number of female exclusive configurations. These include rear reversing radar, SEK certified antibacterial fabric seats, Nanoyi water ion generator, tissue bags, sunshade cosmetic mirrors and other configurations.

4. generally speaking, indoor louvers can only block 17% of the solar radiation heat, while the horizontal sunshade with an outdoor south elevation of 45 degrees can easily cover 68% of the solar radiation heat, and the shading effect between the two is very different. Installed in the window inside the curtain, soft 100 pages and other sunshade facilities, most of the solar radiation heat absorbed will be distributed to the indoor air. If installed on the outside of the sunshade, most of the radiant heat absorbed will be distributed to the outdoor air, thus reducing the effect of indoor temperature. Therefore, the use of external sunshade (sunshade) is the best way to save energy in buildings.

Mugaodi is a big brand in the camping circle. this one is more suitable for going out to party and camping, with a larger sunshade area, only a piece of cloth above, not very windproof, suitable for barbecue and picnic, and the price is not expensive. Party activities can be recommended.

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. For more information about the cost of glass greenhouse in Tibet, please contact Minghao greenhouse Engineering Construction Company directly.

In terms of temperature management, the early growth stage of spring cauliflower cultivation was in the low temperature season, and the growth was small, while the plant size of broccoli was closely related to the flower head yield, and the temperature increased rapidly in the later growth stage, which was disadvantageous to the flower bud differentiation and flower ball formation of broccoli. Therefore, in the field management, it is required to do a good job of heat preservation in the early stage of growth to prevent freezing. Those cultivated in greenhouse should be closed in time to keep warm, those cultivated in open field should be trenched and drained as soon as possible to prevent freezing, and the remedial method of covering the floating surface of sunshade net should be adopted in case of sudden frost or freezing weather. In the later stage of growth, after the temperature rises in April, the protected cultivation should do a good job of ventilation and cooling in time, and the flower heads should be harvested in time after maturity.
