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.
Prevention Tips:? Reasonable increase and decrease of clothes for children, try to change into cotton clothes that absorb sweat as much as possible; encourage children to drink more warm water, can drink a small amount of light salt water, supplement electrolytes lost by sweating in the body; and avoid two hours before and after noon in outdoor activities. Children can wear sunshade hats. In case of mild heatstroke, you can use a cold towel to cool the child physically, but be careful not to apply cold compress on the front chest and abdomen.
Generally speaking, the outer sunshade can keep most of the solar radiation out of the window, while the inner sunshade only partially reflects the solar radiation that has entered the room. Although the effect of external shading is much better than internal shading, internal shading is still widely used, mainly in the form of curtains and blinds. The main forms of external shading are sunshades and sunshades and so on.
This category mainly refers to the use of manually adjustable (including manual adjustment and manual control of electric adjustment) shading facilities (sunshade panels, blinds, curtains, etc.) or selection of transparent materials (such as photoelectric glass, sunshade type Low-e coated glass, etc.) to adjust the angle and length of shade blades according to sunshine angle, sunshine time and environmental conditions in different areas and seasons in order to control light. Keep the strong light outside in summer to reduce the cooling energy consumption, and the warm sunshine in winter into the indoor to reduce the heating load.
Each RV has more than 600 square lawns, wide space and a camping tent platform in front of the RV. The big sunshade does not have to worry about the sun exposure, a few friends get together for barbecue, small hot pot or picnic, and the children gather on the grass to play in the game area, which is an excellent choice to be close to nature and bring their families.
Multi-span greenhouse is a transformation mode of single-arch greenhouse, due to the high utilization rate and the level of mechanization and automation of multi-span greenhouse. From the multi-greenhouse environmental control system electric sunshade electric film coil (window ventilation, electric insulation, quilt, electric fan, water curtain cooling greenhouse environmental control ability is stable, reasonable, high efficiency does not need too much manual operation, just press the switch of the distribution cabinet.
