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.
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.
Cixian County in the building to meet the design requirements of the premise, the addition of external sunshade, awning and appropriate increase in the length of the southward balcony can play 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.
Solutions: strengthen leek field management, control temperature and humidity, timely watering, pay attention to cooling and such work in summer, greenhouse planting can be cooled and protected from the sun by building a sunshade net. Pay attention to guard against cold snap in early spring and late autumn and reduce the occurrence of frost injury. Secondly, through the vents on both sides of the greenhouse to adjust the temperature in the greenhouse, it is best to control the temperature between 20 and 30 degrees. The greenhouse can be covered with grass to keep warm in winter.
The car key door can be pulled out in two different gears, one of which is powered by a CD player. I just got it and changed a battery when I ran out of power. When I first got it, there was a noise in the back of the rear seat, the right rearview mirror was loose, the electric adjustment of the rearview mirror failed, the speedometer did not work (the fault was cured after changing the battery), the CD machine did not read the disc smoothly, and the front fog light was not lit. The rearview mirror reading lights and sunshade make-up mirror lights are not lit (the front car owner did not connect the line when the roof was packed), the rising window of the right front window was slow, and the valve chamber cover and steering power tubing leaked oil.
