Detailed description of the preferred embodiments
The terms "first," "second," "third," "fourth," and the like (if any) of the herein are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," or "having," and any variations thereof, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For convenience of understanding, a specific flow of an embodiment of the present invention is described below, and referring to fig. 1, a first embodiment of a method for setting a sunshade of a substation building according to an embodiment of the present invention includes:
s101, presetting a maximum sunshade coefficient threshold value and a minimum lighting coefficient threshold value of a substation building.
It should be noted that it is the current development trend to reasonably use outdoor sunshade of the window and realize the energy-saving and consumption-reducing technology of the air conditioning system. Practice proves that the external sunshade of the window is more effective in reducing the solar radiation amount of a room than the internal sunshade, and if a building window considers a proper external sunshade measure, the solar radiation heat can be reduced by even 80%, so that the energy consumption of an indoor air conditioner of the building can be reduced, and the aims of saving energy and reducing consumption are fulfilled.
The solar radiation energy consumption of the outer window is caused by the cold load formed by the solar radiation of the outer window, the cold load formed by the solar radiation of the outer window is reduced, and the energy consumption of the air conditioner can be effectively reduced.
The shading coefficient is the ratio of the amount of solar radiation penetrating into the outer shading window to the amount of solar radiation penetrating into the outer shading window in the time of direct sunlight irradiation. The smaller the shading coefficient is, the smaller the amount of solar radiation entering the room through the window is, and the better the heat-proof effect is.
Therefore, in order to reduce the energy consumption of the air conditioner of the substation building, it is necessary to reduce the sun-shading coefficient of the building, and in order to achieve a better effect, the maximum threshold value of the sun-shading coefficient is 0.35, that is, the sun-shading coefficient is less than or equal to 0.35.
In general, "light factor" (daylight factor) is commonly used as an evaluation index of natural light. The lighting coefficient is the ratio of the illuminance generated by directly or indirectly receiving the sky diffused light from the assumed and known sky brightness distribution at a point on a given plane in the room to the illuminance of the sky diffused light generated by the hemisphere of the sky at the same time on an outdoor unobstructed horizontal plane. The lighting coefficient used is the total cloudy model, and the result under the most adverse condition is considered.
The lighting coefficient takes into account the influence of three light components, which are a skylight component, an outdoor reflected light component, and an indoor reflected light component.
Research shows that when the lighting coefficient C is less than 2%, the illumination is insufficient; 2% < C <7%, bright; 7% < C <10%, very bright; c >10%, glare may be caused, and therefore, in the present embodiment, the minimum threshold value of the lighting coefficient is 2%, that is, the lighting coefficient is greater than or equal to 2%.
Therefore, in the embodiment, the sun-shading coefficient is less than or equal to 0.35, and the lighting coefficient is more than or equal to 2%.
S102, selecting a sun-shading device of the transformer substation building according to a preset maximum threshold value of the sun-shading coefficient and a preset minimum threshold value of the lighting coefficient.
It can be understood that solar protection devices include horizontal solar protection structures, perpendicular solar protection structures, synthesize solar protection structures and baffle solar protection structures, wherein, horizontal solar protection structures is for can sheltering from the mode that penetrates from the window top, and perpendicular solar protection structures is for can sheltering from the sunshine that penetrates from the window both sides, synthesizes two kinds of solar protection structures including horizontal and perpendicular simultaneously, and baffle solar protection structures is for can sheltering from the sunshine that level arrives the window, for example, fixed tripe, lattice sunshade etc.. Because the baffle sunshade structure influences the daylighting effect easily, therefore, in this embodiment, do not consider baffle sunshade structure, only consider horizontal sunshade structure, perpendicular sunshade structure and comprehensive sunshade structure.
Specifically, the sunshade device for selecting the transformer substation building according to the preset maximum sunshade coefficient threshold value and the preset minimum daylighting coefficient threshold value comprises: acquiring a relation table of the cantilever coefficient, the shading coefficient and the lighting coefficient of the horizontal shading structure, a relation table of the shading coefficient, the shading coefficient and the lighting coefficient of the vertical shading structure and a relation table of the cantilever coefficient, the shading coefficient and the lighting coefficient of the comprehensive shading structure; comparing a preset maximum sunshade coefficient threshold value and a preset minimum daylighting coefficient threshold value with a sunshade coefficient and a daylighting coefficient of a horizontal sunshade structure, a sunshade coefficient and a daylighting coefficient of a vertical sunshade structure and a sunshade coefficient and a daylighting coefficient of a comprehensive sunshade structure respectively; if the preset maximum threshold value of the sun-shading coefficient and the preset minimum threshold value of the lighting coefficient are met, selecting the corresponding sun-shading structure as a preselected sun-shading device; judging the number of the preselected sun-shading devices, and if the number of the preselected sun-shading devices is one, selecting the preselected sun-shading devices as sun-shading devices of the transformer substation building; and if the number of the preselected sun-shading devices is more than two, comparing the sun-shading efficiency of the preselected sun-shading devices, and selecting the preselected sun-shading device with the minimum sun-shading efficiency as the sun-shading device of the transformer substation building.
