As we all know, the main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, to a certain extent, it can reduce the burning inside the car, and prevent leather seats and dashboards from being damaged by ultraviolet rays. But there are still some car owners who doubt whether sunshade really has the above effect.
The annual solar radiation analysis provides a basis for the design width of the outdoor terrace for self-shading of the building, and also becomes the basis for the use of external perforated aluminum sunshades to optimize and reduce solar thermal gain. These measures, together with double-layer insulated low-E glass, provide efficient shading and thermal insulation, ensuring adequate natural light throughout the building while reducing solar heat gain and energy consumption.
McDonnell Douglas 001 is equipped with a suspended McDonnell Douglas 001LED display dashboard and a small solar panel on the front sunshade, which can power the dashboard and body lighting parts or batteries. This greatly improves the durability of the car.
The main factors that affect the normal work of car audio in autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine.
In the hot summer sun, the temperature in the car can rise to the point where it is impossible to enter, and car shading is a convenience that can slow down the warming rate. But even if they are all called car umbrellas, car sunshades, some are suitable for affixing on the outside of the car, and some can be fixed inside the car; they can also be subdivided into front windshields or side windows, plus the size and function are not the same, how to choose and buy is also a perplexing problem.
If the car sunshade, the protection of the car is still very effective, from the perspective of protecting the car interior, hanging the car sunshade can avoid direct sunlight on the car interior, resulting in unnecessary losses of car owners. The foam of the car sunshade is a poor conductor of thermal energy, and the aluminum foil is affixed to form a specular reflection of sunlight, so the windshield and the car form a thermal insulation layer, which in principle can protect against the sun and cool down.
In addition, the multi-layer umbrella also has a very good UV shielding effect, tested with a detector, the UV value is 3605 without a sunshade, and the value drops to 009 after using a sunshade, and the insulation effect is also very good. Without shelter, the dashboard temperature is nearly 60 degrees, while after using a sunshade, the temperature drops to more than 20 degrees.
So as to provide good indoor work when it is cold at night in winter, the closure of the sunshade can effectively prevent the loss of heat in the greenhouse and play the role of energy saving and heat preservation. According to the planting of crops. To ensure the reasonable function of sunlight, the name shading rate, energy saving rate, standard width, aluminum foil, inner shade, heat preservation type, aluminum foil inner shade, air permeable type, external shade, longevity, external shade, folding, folding,%% window system, gear and rack continuous window opening system is a window starting form often used in large multi-span greenhouse. The system runs smoothly, safely and reliably. In this system, the deceleration motor drives the gear to rotate through the drive shaft, the gear meshes the rack to make it move back and forth in a straight line, and the end of the rack is connected to the support of the ventilation window. So as to realize the opening and closing of the ventilation window. Choose the outer shading screen with different shading rates, which can make the sunlight diffuse in the greenhouse.
