Detailed Description

For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present invention and the descriptions thereof are for illustrating the present invention only and are not to be construed as limiting the present invention.

It is noted that the terms "comprises" or "comprising" when utilized in various embodiments of the present application are indicative of the existence of the claimed function, operation or element and do not limit the addition of one or more functions, operations or elements. Furthermore, as used in various embodiments of the application, the terms "comprises," "comprising," and their cognate terms are intended to refer to a particular feature, number, step, operation, element, component, or combination of the foregoing, and should not be interpreted as first excluding the existence of or increasing likelihood of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing.

In various embodiments of the application, the expression "or" at least one of B or/and C "includes any or all combinations of the words listed simultaneously. For example, the expression "B or C" or "at least one of B or/and C" may include B, may include C or may include both B and C.

Furthermore, terms such as "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Firstly, an enclosure structure is described, wherein the enclosure structure refers to an enclosure structure of each side of a building and a room, and is divided into a transparent enclosure structure and an opaque enclosure structure, wherein the opaque enclosure structure comprises walls, roofs, floors, ceilings and the like, and the transparent enclosure structure comprises windows, skylights, balcony doors, glass partitions and the like. The outer enclosure structure and the inner enclosure structure can be used according to whether the outer enclosure structure is in direct contact with outdoor air or not. The enclosure structure in this embodiment refers to a peripheral enclosure structure of a building, including an outer wall surface, a roof, a window, a balcony door, an outer door, and a partition wall and a door of a non-heating stairwell.

Secondly, the energy interaction between the outer surface of the building and the climate is described, the outer surface of the building is provided with a transparent enclosing structure and a non-transparent enclosing structure, the transparent enclosing structure conducts heat transfer or radiation heat exchange with the outside, the non-transparent enclosing structure conducts energy interaction mainly through heat transfer, the transparent enclosing structure and the non-transparent enclosing structure jointly form the energy consumption of refrigerating and heating of the building, but the heat exchange mechanism and the heat exchange quantity of the transparent enclosing structure and the non-transparent enclosing structure are greatly different. The solar radiation heat gain of the transparent enclosure structure in the south, east and west directions can obviously reduce heating energy consumption, the heat loss of the transparent enclosure structure in the adverse direction increases heating energy consumption, the solar radiation heat gain and the heat transfer heat gain of the transparent enclosure structure in summer both increase refrigeration energy consumption, and the solar radiation heat gain is far greater than the heat transfer heat gain of the transparent and non-transparent enclosure structure. The heat transfer of the non-transparent enclosure structure is achieved in summer, the refrigeration energy consumption is increased, the heating energy consumption is increased due to heat loss in winter, and the influence on the heat transfer is small.

As described above in the background art, the basis of the conventional building body design method is to consider that all the outer enclosure structures are unfavorable surfaces for increasing the cold/heat consumption of the building, but for the solar energy enrichment region, the south transparent enclosure structure can obtain a large amount of solar radiation heat in daytime, and the heat loss of the building is compensated, so that the heat consumption of the building is reduced, and the long-strip building adopting the large-area transparent enclosure structure in the south of the severe cold region is beneficial, and the body energy saving coefficient is larger than that of the point-type building, but the building energy consumption is greatly reduced. The traditional building body design method considers that all external surface areas of the building are adverse surfaces, heat loss in winter and heat acquisition in summer are linearly related, and the beneficial influence generated by solar radiation is ignored. Meanwhile, in the analysis of the traditional technology, the heat consumption or the cold consumption of the transparent enclosure structure in unit area is equal to the heat consumption or the cold consumption of the non-transparent enclosure structure in unit area, and the heat consumption or the cold consumption of the transparent enclosure structure in unit area is different from the heat consumption or the cold consumption of the non-transparent enclosure structure in unit area, so that the load utilization of heat supply equipment or summer cold supply equipment of a building in winter cannot be realized to the greatest extent, and the energy consumption of energy consumption equipment in the building is increased.

Therefore, in order to solve the problem that the existing building shape design calculation method ignores the interaction between the building and the climate energy and further cannot maximally realize the load utilization of the heat supply equipment or the cold supply equipment in summer, which results in the increase of the energy consumption of the heat supply equipment or the energy consumption of the heat supply equipment in winter, the embodiment provides a building design method, a system and equipment based on the interaction between the building and the climate energy, the invention combines the outer surface area of the non-transparent enclosure structure of the building, the outer surface area of the transparent enclosure structure, the building orientation and the energy consumption parameter to obtain a novel building body energy-saving coefficient, improves the correlation between the body of the building and the energy consumption of the energy consumption equipment based on the body energy-saving coefficient, and can be applied to the energy consumption analysis of the building in various climatic regions so as to guide building designers to adjust the design in aspects of building body, space, material, structure and the like and reduce the energy consumption of the energy consumption equipment in the building.

Correspondingly, the energy consumption equipment installed in the building can comprise cooling equipment and/or heating equipment, wherein the cooling equipment mainly comprises a water chilling unit, a split air conditioner, a multi-split air conditioner and the like, and the heating equipment mainly comprises an air-cooled heat pump unit, a ground source heat pump unit, a water source heat pump unit, a gas boiler and the like.

Referring to fig. 1, fig. 1 is a schematic flow chart of a building design method based on interaction of building and climate energy, as shown in fig. 1, the method includes the following steps:

S110, acquiring a first outer surface area and first energy consumption of the non-transparent enclosure structure of the building, and outer surface areas and second energy consumption of the transparent enclosure structure of the building in a plurality of directions.

In this embodiment, as a common sense of a person skilled in the art, heat transfer indexes of walls and roofs of the non-transparent enclosure structures of the building in each direction per unit area are close, so that energy consumption of the non-transparent enclosure structures in different directions is not considered in this embodiment. But for transparent structures, based on what is described in the above embodiments: the solar radiation heat gain of the transparent enclosure structure in the favorable directions (south, east and west) in winter can obviously reduce heating energy consumption, the heat loss of the transparent enclosure structure in the unfavorable directions increases heating energy consumption, the solar radiation heat gain and the heat transfer heat gain of the transparent enclosure structure in summer both increase refrigeration energy consumption, and the solar radiation heat gain is far greater than the heat transfer heat gain of the transparent and non-transparent enclosure structure. Therefore, the embodiment considers the heat obtaining characteristic and the heat losing characteristic of the non-transparent enclosure structure and the transparent enclosure structure all the year round, and solves the problem that the building body design method is seriously not adapted because the heat consumption/cold consumption of the transparent enclosure structure in unit area is consistent with the heat consumption/cold consumption of the non-transparent enclosure structure in unit area considered by the prior art.

The building refers to a house, namely, an engineering building for people to live, work, learn, produce, manage, entertain, store articles and perform other social activities. In this embodiment, the plurality of orientations are based on the shape of the building, such as a quadrilateral house, with the roof of the house being a non-transparent enclosure, i.e. the house comprises four orientations.

S120, determining third energy consumption of the orientation of the transparent enclosure structure according to the outer surface area and the second energy consumption.

In particular, a building may include a variety of shapes, such as a building perimeter including a quadrilateral, a circle, a pentagon, a hexagon, and the like. The roofs of buildings can be broadly divided into four categories in terms of roofing: flat roofs, pitched roofs, curved roofs, and multi-wave folded roofs.

Flat roof: the maximum gradient of the roof is not more than 10%, and the common gradient of civil buildings is 1-3%. Slope roof: the roof gradient is larger and is more than 10 percent. There are various forms such as single slope, double slope, four slope and hill rest. Single slopes are used for small spans of houses and double and four slopes are used for larger spans of houses. Curved roof: the roof is shaped into various curved surfaces, such as spherical surface, hyperbolic paraboloid, etc. Multi-wave folded plate roof: is a multi-wave roof made of reinforced concrete thin plates. The folded plate has a thickness of about 60 mm, a wavelength of 2-3 m, a span of 9-15 m, and an inclination angle of 30-38 degrees. The cross-sectional shape of each wave is triangular and trapezoidal.

Because the shapes of the periphery and the top of the building are more, the heat obtaining characteristic and the heat losing characteristic of the building are different under the climatic conditions, and therefore, the third energy consumption of the unit area corresponding to the orientation of the transparent enclosing structure is required to be determined according to different orientations of the building.

S130, determining fourth energy consumption of the non-transparent enclosure structure according to the first outer surface area and the first energy consumption.

The energy consumption device is determined as an air conditioner in this embodiment, and the air conditioner has a cooling or heating effect, is very common energy consumption device installed in a building, and as a whole, the air conditioner is used for refrigerating in summer and heating in winter all the year round. For example, in summer, the transparent enclosure structure can consume a lot of cold energy generated by the air conditioner, and in winter, the transparent enclosure structure can consume a lot of heat energy generated by the air conditioner. Therefore, the energy consumption is the sum of the heat consumption and the cold consumption of the non-transparent enclosure structure or the transparent enclosure structure.

And S140, determining an equivalent coefficient corresponding to the orientation of the transparent enclosure structure according to the third energy consumption and the fourth energy consumption.

In this embodiment, based on the third energy consumption of the transparent enclosure structure in the unit area and the fourth energy consumption of the non-transparent enclosure structure in the unit area, the equivalent coefficient of the non-transparent enclosure structure and the difference of the orientation of the transparent enclosure structure in the unit area can be determined, and the equivalent coefficient characterizes the association relationship between the energy consumption of the transparent enclosure structure in the unit area and the energy consumption of the non-transparent enclosure structure in the unit area under the influence of the heat obtaining characteristic or the heat loss characteristic.

S150, determining the equivalent external surface area of the transparent enclosure structure, which is in contact with the outdoor atmosphere, according to the equivalent coefficient and the external surface area.

The meaning represented by the equivalent coefficient can determine the equivalent external surface area of the transparent enclosure structure in contact with the outdoor atmosphere, so as to define the equivalent relationship between the transparent enclosure structure and the energy consumption of the energy consumption equipment under the unit area of the non-transparent enclosure structure.

And S160, calculating the energy-saving coefficient of the building body according to the first external surface area, the equivalent external surface area and the volume surrounded by the building.

In this embodiment, the calculation of the volume enclosed by the building is common knowledge to the person skilled in the art, and redundant explanation is not made here. F represents the outer surface area of the building in contact with the outdoor atmosphere, and V represents the volume enclosed by the building. The energy saving coefficient of the building body is calculated by dividing the transparent enclosure structure into a non-transparent enclosure structure, dividing the transparent enclosure structure into different directions, calculating the transparent enclosure structure in different directions as a non-transparent enclosure structure area in an equivalent coefficient mode, and determining the energy saving coefficient of the building body by using the external surface area of the equivalent enclosure structure and the volume surrounded by the building.

S170, analyzing the load of energy consumption equipment installed in the building according to the building body energy-saving coefficient to obtain the building energy consumption analysis result.

In this embodiment, according to the building form energy saving coefficient determined in the above step S160, a designer of a building may simulate the energy consumption of the energy consumption device under different window wall ratios by changing the window wall ratio of the building, observe whether the annual load of the energy consumption device per unit area of the building is in a linear relationship with the building form energy saving coefficient, so as to analyze the load of the cooling or heating device installed in the building, and use the final linear relationship diagram as the energy consumption analysis result of the energy consumption device in the building, for example, when the form energy saving coefficient is smaller, the energy consumption of the energy consumption device is smaller.

Therefore, the building design method based on interaction of building and climate energy provided by the embodiment separately calculates the heat obtaining or losing conditions of the transparent enclosure structure in different directions to obtain the equivalent coefficients of the transparent enclosure structure in different directions, and uses the equivalent coefficients to perform the equivalent on the outer surface areas of the transparent enclosure structure in different directions, and distinguishes the heat consumption or cold consumption of the transparent enclosure structure in unit area from the heat consumption or cold consumption of the non-transparent enclosure structure in unit area, so as to determine the equivalent outer surface area of the transparent enclosure structure, and finally, the building shape energy-saving coefficient is calculated through the outer surface area of the non-transparent enclosure structure, the equivalent outer surface area of the transparent enclosure structure and the enclosed volume of the building, and further, the load of the cooling or heating equipment installed in the building is analyzed based on the building shape energy-saving coefficient, namely, the window wall ratio is changed, the building energy consumption under different window wall ratios is simulated, the annual load of the building air conditioner in unit area is observed, and the energy consumption result of the cooling or heating equipment in the building is simulated, and the energy consumption of the cooling or heating equipment in the building can be applied to the energy consumption of various climate areas of the building, so that the design personnel can conveniently guide the design space, the energy consumption of the building, the design personnel can be reduced, and the energy consumption of the design equipment is convenient.

In one embodiment, before the step of obtaining the first external surface area and the first energy consumption of the non-transparent enclosure of the building, and the second energy consumption of the transparent enclosure of the building in the plurality of orientations, the method further comprises:

and carrying out dynamic heat transfer analysis on the three-dimensional geometric model of the building to obtain a dynamic heat transfer calculation result, and calculating the first energy consumption of the non-transparent enclosure structure and the second energy consumption of the transparent enclosure structure in a plurality of directions according to the dynamic heat transfer calculation result.

Specifically, a three-dimensional geometric model of the full size of the building can be created by SCetthUp software. Since the full-size three-dimensional geometric model is determined, the outer surface areas of the transparent enclosure of the building in a plurality of directions and the first outer surface areas of the non-transparent enclosure can be determined through corresponding calculation.

Further, the three-dimensional geometric model is imported into Energyplus software to conduct dynamic heat transfer analysis of typical weather year round, and the sum of reference heat consumption and cold consumption of the non-transparent enclosure structure, namely the sum of accumulated heat consumption and cold consumption of the non-transparent enclosure structure in unit area year round is calculated based on the annual dynamic heat transfer calculation result.

In one embodiment, the determining the third energy consumption of the transparent enclosure according to the outer surface area and the second energy consumption specifically includes: summing the second energy consumption of the transparent enclosure structures in each direction, and determining the second energy consumption sum of the transparent enclosure structures in each direction; summing the outer surface areas of the transparent enclosing structures in each direction, and determining a second outer surface area of the transparent enclosing structures in each direction, which is in contact with outdoor atmosphere; taking the ratio of the sum of the second energy consumption of each direction to the second external surface area as the third energy consumption of the unit area of the transparent enclosure structure in each downward direction;

In one embodiment, the fourth energy consumption of the non-transparent enclosure is determined according to the first external surface area and the first energy consumption, specifically: taking the ratio of the first energy consumption of the non-transparent enclosure structure to the first external surface area of the non-transparent enclosure structure as fourth energy consumption of the unit area of the non-transparent enclosure structure;

Wherein the calculation formula of the fourth energy consumption is Wherein, Q _{n,i, Summer with air conditioner} is the annual cumulative cooling consumption of the unit area non-transparent enclosure when facing i, and Q _{n,i, Winter} is the annual cumulative cooling consumption of the unit area non-transparent enclosure when facing i, i.e. the first energy consumption; Indicating the first external surface area of the non-transparent enclosure structure with the direction i, COP indicating the heating performance coefficient, EER indicating the cooling performance coefficient, and n indicating the non-transparent enclosure structure.

In this embodiment, since the heat transfer index of the non-transparent enclosure structure is relatively close in each direction of the unit area, the fourth energy consumption is calculated by using an average value, and the directions include, for example, a plane direction of east, south, west, north, etc. of the building and a three-dimensional direction of a roof, etc.

Accordingly, when the power consumption is calculated, the COP/EER (heating/cooling cost) of the heating season and the cooling season is different, so that the absolute value summation is required to be carried out after the heating season and the cooling season are calculated separately, and the annual accumulated power consumption of the transparent enclosure structure in unit area is obtained.

In one embodiment, determining the equivalent coefficient corresponding to the orientation of the transparent enclosure structure according to the third energy consumption and the fourth energy consumption specifically includes: the ratio of the third energy consumption of the unit area of the transparent enclosure structure in each direction to the fourth energy consumption of the unit area of the transparent enclosure structure is used as the equivalent coefficient of each direction of the transparent enclosure structure; wherein, the calculation formula of the equivalent coefficient is: in which, in the process, To accumulate power consumption throughout the year for a unit area transparent enclosure with an orientation of i, i.e. the third energy consumption is performed,The reference power consumption of the non-transparent enclosure structure, namely fourth power consumption, and t represents the transparent enclosure structure.

In this embodiment, the energy saving coefficient of the building body is calculated by splitting the transparent enclosure and the non-transparent enclosure, distinguishing the transparent enclosure with different directions, and equivalent the transparent enclosure with different directions into the non-transparent enclosure area in the form of equivalent coefficient, and calculating the ratio of the final equivalent external enclosure area to the building volume.
