Generally speaking, the horizontal sunshade with an outdoor south elevation of 45 °can easily cover 68% of the solar radiation heat. Installed in the window inside the curtain, soft 100 pages and other sunshade facilities, most of the solar radiation heat absorbed by it is distributed to the indoor air. The sun visor installed on the outside absorbs most of the radiant heat and distributes most of the outdoor air, thus reducing the impact on indoor temperature. Therefore, the use of external sunshade (sunshade) is a better way of building energy saving. Intelligent design of sunshade system.
For a long time, Emperor Chen Yu doors and windows have always been committed to home doors and windows heat preservation and energy conservation, sunshade and thermal insulation work. The broken bridge window system selects scientific and reasonable sealing profile, flexible adhesive strip seamless sealing lap joint, super-large glass hollow layer by layer protection, which can greatly improve the thermal insulation performance of the house, reduce the temperature of the room exposed to the sun, and reduce the influence of western sunlight.
Therefore, in the structure of the window, in order to be able to control the illuminating effect of sunlight, the area of the window wall should not be too large. If the window area is relatively large, it should be considered to choose heat reflection glass, endothermic glass or other shading methods, such as eaves, eaves, sunshade panels, window cloths and so on to block the absorption of heat. Improve the airtightness of doors and windows and reduce the number of ventilation in the room. For example, the selection of outstanding airtight doors and windows, or the addition of closed bars on doors and windows can improve the airtightness of doors and windows. Choose the automatic control system. The automatic control system includes energy control of cold and heat source, fresh air volume control, quantity control of air conditioning system, start and stop time and operation mode of equipment, supply air temperature control, temperature and humidity setting control and so on. The automatic control system can complete the convergence management and good control of the air conditioning system, and guess the air state parameters (temperature, humidity, enthalpy, concentration, etc.) in the room surface to keep the indoor environment comfortable.
Car sunshade is currently used more sunshade products, now the market is more commonly used is aluminum film PVC material, this material can better refract light, and PVC internal bubbles have a better insulation heat transfer, can effectively play the role of thermal insulation, then a series of down can be concluded, we choose the material is good or bad to determine the use effect, so we choose the sunshade board Choose a model that can have a sucker, although it is more difficult to place it, but without a sucker, it will easily fall off the windshield, thus losing the meaning of shading and wind shielding. so when we buy this product, try to choose a thicker one, so the effect will be better than the ordinary one.
The heat preservation work in the greenhouse can be completed by side insulation and top insulation curtain, as well as internal and external sunshade curtain and top skylight. The heat preservation work can be carried out 2 hours before sunset. Close the top skylight 2 hours before sunset, expand the internal heat preservation, and then gradually expand the internal sunshade and side insulation. All the internal heat preservation, inner sunshade and side heat preservation will be carried out before sunset. If necessary, external shading can also be fully carried out for thermal insulation. When the external solar radiation is less than 300W/m2 (blade stomata closed) and need heat preservation, you can directly turn on internal heat preservation, side heat preservation and internal shading, and close the top skylight at the same time.
In addition to choosing the right venue, the items needed for camping are also very important, for example, clothes should be as comfortable as possible. In addition, suitable tents are a must, and air mattresses, picnic mattresses and folding tables and chairs should be chosen as easily as possible to achieve a comfortable reception. In addition, the canopy is a good sunshade, it is recommended that one step in place, to be durable and windproof.
Under the premise of meeting the design requirements of the building, adding external sunshades, awnings and appropriately increasing the length of the southward balcony can have a certain sunshade 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.
Chengmai County, Hainan-supplying diesel oil (Lingshui County News) at present, spray-free plastic has been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, dashboards and other auto parts in the automotive field. Bioplastics bioplastics are produced by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics are generally synthesized from petroleum products, which are often harmful to small molecules that do not fully react, while bioplastics are prepared into automobile interior parts for VOCs volatilization in large vehicles because of the use of renewable raw materials with low toxicity and low harm. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic.
