For me, having passed the age of several convenience store sandwiches and a dozen cold beers to lie on the grass all afternoon, it is not a waste of time for a picnic to meet at least four points: “sitting comfortably, sunshade in place, room for things, and drinks and beer cold enough”.
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;
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 Zhuzhou conjoined greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied. For more information about the cost of Zhuzhou conjoined greenhouse, please contact Minghao greenhouse Engineering Construction Company directly.
In addition to selecting appropriate insulation materials, the correct insulation treatment technology is adopted to form a complete protective layer on the insulation exterior. For protection against sunlight, a sunscreen can be installed at the top of the shell, and there should be a certain distance between the sunshade and the shell to avoid direct heat transfer. In recent years, the cooler is often put on the stator. In order to avoid the condensation of the motor, a moisture-proof heater can be installed. Outdoor motors can be treated similarly according to tropical motor insulation.
The weekend was sunny and sunny, and the time was just right for the family of three to come by themselves. First sign in, familiarize themselves with the venue, and then move freely. As a photography enthusiast, you must take pictures when you see the beauty of the outdoors. Have to praise the staff, the venue is very well arranged, wooden seats, sunshade cloth, drinks, snacks, really satisfy all my imagination for a picnic.
As we all know, temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.
In addition to the outdoor camping folding car, GAC MOTOR APP also has a lot of equipment necessary for outdoor camping. For example, outdoor sunshade canopy, outdoor folding seats, outdoor camping tableware sets and outdoor picnic mats and so on. For those of you who like camping, come and buy it on GAC MOTOR APP.
4. To prevent heat and cool down, many pickup trucks do not have air conditioning, and the dashboards are often scorched in the summer sun. At this time, some drivers will spread wet towels on them, which can play a cooling role. In fact, it is hard to say how much the temperature can be reduced, but at least there is a towel full of cold water in front of you, which will make you feel more comfortable psychologically. Some car owners will also put sunshade pads on the workbench, which can not only improve the appearance of the car, but also cushion the light and make the light look softer, thus reducing the unnecessary danger caused by weak light.
(2) adjustable shading facilities should be used in ultra-low energy consumption buildings. The heat absorbed by the sun absorbed by the external sunshade surface can be adjusted automatically or manually according to the sun height angle and outdoor weather conditions, and the proportion of the sun absorbed by the external sunshade surface is smaller than that of the inner or middle shade. It is the most suitable shading form for ultra-low energy consumption buildings. The schematic diagram of the adjustable external shade and adjustable sunshade of the lifting louver is shown in figure 10;
However, the effect of indoor shading is not as good as external shading, it only blocks the light, but not the heat. When the light encounters the inner shading facilities, the radiant heat has already entered the room through the glass, and the glass temperature will rise very high. As for the external sunshade, only that part of the sunlight will reach the outer surface of the glass window directly. In general, bright indoor blinds can only block 17% of the solar radiation heat, while the outdoor horizontal sunshade with an elevation of 45 °south can block 68% of the solar radiation heat. The shading effect of the two is very different.
From the analysis of the environmental factors closely related to plant growth in greenhouse project, different temperature and humidity will have a direct impact on plant growth. Therefore, how to meet the requirements of different crop growth environment has become the main way to improve the production potential of greenhouse and realize factory planting. The intelligent greenhouse control system can not only monitor the internal environmental data of the greenhouse, set the upper and lower values of various environmental indicators, and remind managers of the abnormal situation of the greenhouse environment, but also work together by controlling the external sunshade, internal shading, internal thermal insulation, top natural ventilation system, fan water curtain forced cooling system, heating system and so on, so as to make the internal environment of the greenhouse within the scope of our design.
