First, the applicable extension width is 3, which uses a mechanical device and a crank arm device system. Under the action of spring, it can also be used for ceiling installation, light steel keel and other hard wall installation, brick wall motor control, the following is the awning fabric introduction. 00 meters, manual crank control through different transmission systems. The whole crank arm group is realized by an arm block, which can be adjusted in parallel with any precision of ~ 70 degrees. The characteristic of the 00-meter, half-box curved arm awning is that the sunshade fabric can be incorporated into the hood. Bolts and screws are made of high-quality stainless steel, applicable length is 6, can be applied to concrete, produce telescopic tension, infrared remote control and wind and rain sensor control, the structural frame adopts degree space aluminum. Wood. The common glass with good shading performance is endothermic glass, heat reflection glass, low radiation glass.
Of course, car owners can also choose to use sunshade gears. The most important thing is to block out the sun so that the sun cannot enter the car. To a certain extent, it reduces the combustion effect of the car and avoids the effect that the leather seat and dashboard are damaged by ultraviolet light.
The main contents are as follows: 1) the structural design of the window should be reasonable. In the design of the building window, it should not only reflect the control effect of the window on sunlight, but also limit the volume ratio of the window to the wall. If the window area of the building is relatively large, endothermic glass or heat reflection glass can be used, and other shading measures such as balconies, curtains and sunshades can also be taken. If the outdoor temperature is low, natural air can be used as a direct source of energy. Therefore, when designing the construction of the window, you can set a natural pass on it that can open the shoulder;
According to the management of medium-and long-term weather forecast, in case of continuous low temperature, the temperature of the mushroom house / shed should be kept above 8 °C ~ 10 °C. The main measures for heat preservation and warming include: thickening the roof cover at night; hanging blankets on doors; closing doors and windows for heat preservation in the morning and evening; opening doors and windows around noon in sunny days; opening only leeward vents for short-term ventilation in rainy and snowy weather; in cold or windy weather, close doors, windows and vents to prevent cold air from attacking. When the weather is fine, open the cover to increase the temperature of the light, when the light is strong, it is best to set up a sunshade net under the greenhouse film and above the bacterial stick to protect the light and heat. If there are heating facilities such as hot air stove, the temperature of the mushroom room / shed can be increased by heating, but attention should be paid to prevent the smoke from being discharged into the shed and cause poisoning. In addition, the ditch cleaning and drainage of the mushroom shed should also be done to reduce the humidity in the greenhouse in the rainy season and improve the mushroom quality.
The sun board integrates daylighting, thermal insulation and sound insulation, which 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.
In the case of ensuring good thermal insulation performance of doors and windows, we can also add external sunshade panels, awnings and appropriately increase the length of southward balcony, which can also play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which not only has a decorative effect, but also forms a poor mobility space layer with a thickness of about 50mm between the glass and the curtain. Of course, in order to ensure that the indoor lighting effect will not deteriorate as a result of the renovation of the facilities, these facilities should be mobile and can be changed according to the weather.
External shading mainly refers to covering the sunshade net on the outside of the greenhouse, which directly shields the solar radiation outside the greenhouse, which can effectively reduce the temperature in the greenhouse. At the same time, the external shading system can be active. with the continuous development of science and technology, there are more and more kinds of greenhouses, and greenhouses for cultivating all kinds of plants and organisms are also built, and a variety of methods are used to control the temperature in the heat preservation work. every week, when irrigation is carried out, the end of each drip irrigation pipeline is opened in turn, and the fine particles accumulated at the end of the eyedropper are flushed out with high-pressure water. The pipeline must be opened one by one to ensure sufficient pressure,
In order to prevent the car from being hurt by the sun, many people will buy sunshade for the car. As we all know, the main purpose of car shading is to block the scorching sun, which can reduce the temperature inside the car to a certain extent, and protect leather seats and dashboards from ultraviolet rays.
(2) strengthening the shading measures inside and outside the window on the premise of meeting the design requirements of the building, adding external sunshade panels, awnings and appropriately increasing the length of the southward balcony can play a certain shading effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.
A: the advantage of car sunshade is to block the sun, to a certain extent, to reduce the burning heat inside the car, to prevent leather seats and dashboards from being exposed to ultraviolet light, and to increase privacy, and it is not clear to see inside and outside the car. can increase safety factors.
