Description
Technical Field
The invention relates to the technical field of teaching equipment, in particular to a teaching demonstration device for building shape coefficient energy consumption.
Background
Along with the improvement of the urbanization process and the living standard of people in China, the building energy consumption still has a rigid growth trend, the building energy conservation becomes an important field of the strategy of coping with climate change and energy conservation and emission reduction in China, the problem of high energy consumption index of buildings in China generally exists, especially, the public building energy consumption level with large building space and various shapes is 7-22 times higher than that of a common residential building, the energy consumption in the building operation stage is more than 3/4 of the energy consumption in the whole life stage, and the parameters of the building space, the shape and the like determined in the building design stage are the key for determining whether the energy conservation is realized in the building operation stage. The building build factor refers to the ratio of the external surface area of the building in contact with the outdoor atmosphere to the volume enclosed by the building. The external surface area does not include the ground, the inner wall of the non-heating staircase and the area of the door. The building shape factor is one of the common parameters reflecting the plane shape, building shape and space of the building. Building shape factor is a common control parameter in building energy saving design. Namely:
wherein S is the building shape coefficient; sExternal surface areaThe external surface area (m) of the building in contact with the outdoor atmosphere2) (ii) a V is the building volume (m)3)；sRoof coveringIs the area of the building roof (m)2) (ii) a h is the building height (m); c is the building perimeter (m).
Aiming at comparing the energy consumption of buildings under different form factors in the building energy-saving design, a qualitative analysis method and a quantitative analysis method can be adopted in the prior public reports, and the qualitative analysis generally considers that the building energy consumption tends to be less when the building form factor is lower; the building shape is close to a square, and the building energy consumption tends to be less because the external surface area of the building under the same building volume is less when the building shape coefficient is lower, and the cold and heat loads caused by the heat exchange between the building envelope structure and the outdoor environment are lower. However, the building energy consumption not only includes the energy consumption of heating, ventilating and air conditioning equipment generated by cold and heat loads of the building enclosure, but also includes energy consumption of building illumination, sockets, ventilation, power, special energy consumption and the like, and partial buildings have inner areas, and also include energy consumption of heating and air conditioning of the inner areas of the buildings. The results of actual measurement and simulation data of building energy consumption of some large public buildings show that the relationship between the building energy consumption and the building form factor does not completely accord with the conventional qualitative rule that the building energy consumption tends to be less when the building form factor is lower. The building shape space design is an important content of building energy saving design and an important link of building energy saving design teaching of building colleges and universities, but in the prior art, the demonstration of a data physical method and an energy consumption simulation software modeling analysis method adopted in the teaching demonstration process is too long in time consumption, is only limited to show and demonstration results, and is not beneficial to students to intuitively master the relationship between the building shape coefficient and the energy consumption and the change trend of the building shape coefficient and the energy consumption.
