The overhead ventilated roof is widely used in hot summer and cold winter areas in China, especially in the hot and rainy summer, which shows its superiority. The principle of the ventilated roof is to set up a ventilation room layer on the roof. On the one hand, the outer layer of the ventilation room layer is used to block the sun, such as a closed or ventilated air room layer, and the sunshade intercepts the sun directly shining on the roof. The radiant heat makes the roof heat transfer twice, avoiding the direct action of solar radiant heat on the enclosure structure, on the other hand, using the effect of wind pressure and hot pressure, especially natural ventilation, the solar radiant heat absorbed by the upper and lower surfaces of the sunshade in contact with the air is transferred to the air with the wind. The greater the wind speed, the more heat the roof takes away, and the better the thermal insulation effect is, the greater the thermal insulation capacity of the roof is. So as to reduce the effect of outdoor heat on the inner surface.
After emergence, sunshade and heat preservation should be used to ensure the suitability of the seedling bed temperature to prevent the seedlings from burning when the temperature is too high in sunny days. The film should be watered once when the film is opened after the second leaf stage, and the light available fertilizer should be watered once after the temple during the third leaf period. Do a good job of weed control and spray carbendazim 1 or 2 times to avoid sudden disease.
Century series, and more like German cars. However, the layout of the sub-dashboard is a part of saab. Almost nothing is the original. The Regal seat is said to have been redesigned based on Chinese body data. Regal changed the front seat of the vehicle to eight-direction adjustment on the left and four-direction adjustment on the right. It raises the level of luxury in the interior of the vehicle, especially the special design of the front right seat: two switches are designed on the upper left side of the seat back, so that the rear passengers can easily adjust the front seat to the right position, while the rear controllable devices are also added, such as air conditioning and audio and dvd rear passengers can be easily controlled in the rear. With regard to the price of the Junwei car, the degree of luxury is reasonable. However, the depth of the back row and waist support have not been improved. There are sunshade curtains on the Junwei rear window and the rear two doors and windows so that the scorching sun in summer no longer adds annoyance to passengers.
Secondly, the car sunshade protects the vehicle instrument equipment. Direct sunlight will make the temperature in the car as high as 70 degrees, not only the shell of the center console is easily deformed, but also the instruments and audio equipment on the dashboard will be damaged by high temperature, such as aging parts, unsoldering pins and so on. Sunshades can effectively avoid direct sunlight.
The simplest item in the high temperature test is the exposure test, in which the vehicle is parked in the hot sun with the front facing west, and a temperature display patch is affixed to the engine cover, dashboard, steering wheel and other key parts of the vehicle, and the temperature in the car is as high as 70 or 80 degrees. Then test the door handle, dashboard, sunshade, air conditioning outlet and other internal and external accessories for abnormal noise or functional failure.
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.
Dalian FRP lighting board quotation, the development prospect of sunlight board set daylighting, heat preservation, sound insulation in one, can block the sun and rain, but also heat preservation and light transmission, can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. Foreign countries even appeared in addition to the supporting structure, pure polycarbonate material of large transparent lighting house, a sunshine, crystal transparent, warm and pleasant. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; in terms of greenhouse efficacy, there are production-based greenhouses, trade greenhouses dominated by flower trading centers, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.
Early last Sunday morning, Ms. Yu got up early and went to the underground garage with a lot of online shopping gadgets-the newly bought Mazda 3 became the object she wanted to dress up today. She has a lot of gadgets in her hand, such as the dustbins used in the car, the small puppets placed on the car, and a row of small animals shaking their heads on the dashboard. In order to show that she is a novice, she posted stickers such as “I am a novice” and “you are the teacher, you go first” on both sides of the car, and knitted a tissue box on the sunshade. Before that, she also pasted explosion-proof film, laid floor mats, and installed an original GPS navigation. By rough calculation, she spent more than 6,000 yuan on the decoration of the car. “the car is like a clear water room. it has to be decorated.” Only in this way can I feel like the car is my own, Ms. Yu said.
Therefore, on the whole, it is not recommended to put sunshade pads in the car. Because its refraction ability is not strong, the protection of the center console can be said to be minimal, and even make the temperature of the center console rise. The temperature is relatively high, the car in the sun for a long time will make the car heat up quickly, through the front windshield, the temperature of the center console is hot to hot, many car owners are worried that the center console will be scrapped because of the high temperature. If the center console is broken, maintenance is also a large expense.
Office partition wall aluminum-for sale, built-in louver partition, the aluminum shutter is installed in the hollow cavity of hollow glass, through magnetic drag, to realize the folding and dimming function of the built-in shutter. The technology combines the hollow glass indoor curtains of the external sunshade device into one, which has the effect of all. The louver partition is a louver built in hollow glass, which can realize the rise and fall of the louver, reasonable structure and simple operation. It has good shading performance, improves the insulating performance of insulating glass, improves the indoor light environment, and is widely used in energy-saving building doors and windows.
Jinan District Holiday House Electric curtains how much to inquire, 6. Energy saving and environmental protection: electric shutter windows can achieve the appropriate indoor temperature by adjusting sunshade, which can effectively reduce the heat load of air conditioning, absorb solar radiation energy and reduce heating load in winter, thus playing the role of energy saving and consumption reduction. 5. Heat preservation and heat relief: electric curtains can effectively prevent strong outdoor light, maintain a steady state for indoor temperature, and are more suitable for work.
