Description

The assay method of Architectural Atrium exterior window inleakage
Technical field
The present invention relates to the assay method of field of air conditioning, more particularly to Architectural Atrium exterior window inleakage.
Background technology
Traditional assay method that building room exterior window leaks out mainly includes pneumatic process and tracer gas technique, above two method Application be small room in building, such room feature is that small volume, indoor air flow are relatively stable.Compared to small-sized room Between, the volume of Architectural Atrium is larger, indoor air flow is complex, is that indoor each position can not be ensured using the difficult point of pneumatic process Indoor and outdoor 60Pa pressure difference is kept, is not ensureing that search gas is scattered equal using the difficult point of search gas assay method It is even, in a word, the degree of accuracy of Architectural Atrium exterior window Calculation of Air Leakage result is difficult to ensure that based on existing assay method.
The content of the invention
The present invention provides a kind of survey of Architectural Atrium exterior window inleakage to solve technical problem present in known technology Determine method, this method can greatly improve the measurement accuracy of Architectural Atrium exterior window inleakage.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：Outside a kind of Architectural Atrium Window leaks out quantity measuring method, using following steps：1) type of Zhongting exterior window is determined, counts and obtains each direction of Zhongting exterior window Gap length, LE、LW、LSAnd LNRespectively the four corners of the world to exterior window gap length, unit m；2) one is selected in same building Small room, the exterior window type of the small room is identical with Zhongting exterior window type；3) the exterior window leakage of the small room is determined Air quantity AL and indoor and outdoor pressure differential deltap P, Δ P unit Pa, AL unit m3/(m.h)；4) measuring point of Zhongting, the survey of Zhongting are arranged Point arrangement principle is as follows：A) exterior window of each direction is both needed to arrange measuring point；B) exterior window of each floor is both needed to arrange measuring point；C) survey The height of point is highly identical with the centre position of corresponding exterior window, and indoor and outdoor measuring point is 0.5m with the distance of corresponding exterior window；5) obtain The indoor external differential of each measuring point is taken, and calculates each average pressure difference towards exterior window of acquisition, Δ PE、ΔPW、ΔPSWith Δ PNRespectively The four corners of the world to average pressure difference, unit Pa；6) inleakage of Zhongting exterior window is calculated, formula is as follows：
In formula：
SL --- Zhongting exterior window inleakage, unit m3/h。
The present invention has the advantages and positive effects of：
1) measurement accuracy is high, in continuous mode, takes into full account the influence of direction and the discrepancy in elevation to exterior window inleakage, measure Precision can be guaranteed.
2) assay method is simple, on the basis of traditional assay method, and the indoor external differential for being only additionally arranged some exterior windows is surveyed Point.
3) it is applied widely, the limitation of conventional method is overcome, revised assay method can be widely used in greatly In space buildings.
Brief description of the drawings
The small room point layout figure that Fig. 1 uses for the present invention；
The Zhongting point layout figure that Fig. 2 uses for the present invention.
Embodiment
In order to further understand the content, features and effects of the present invention, hereby enumerating following examples, and coordinate accompanying drawing Describe in detail as follows：
A kind of Architectural Atrium exterior window leaks out quantity measuring method, using following steps：
1) type of Zhongting exterior window is determined, the gap length of each direction of Zhongting exterior window, L is counted and obtainE、LW、LSAnd LNPoint Not Wei the four corners of the world to exterior window gap length, unit m.
2) small room is selected in same building, it is desirable to：The exterior window type of the small room and Zhongting exterior window class Type is identical.
3) the exterior window inleakage AL of the small room and indoor and outdoor pressure differential deltap P, Δ P unit Pa, AL unit are determined m3/(m.h)。
In the present embodiment, exterior window inleakage AL is obtained based on tracer gas technique.Fig. 1 is referred to, 1~4 is interior Gas measuring point, related test reading is carried out based on tracer gas technique, while entering to the gap length of exterior window to above-mentioned 4 measuring points Row measurement count, you can obtain the exterior window inleakage of the small room.Calculation formula is as follows：
In formula：
AL --- window inleakage, m3/(m.h)；
Ct--- the trace gas concentration (vpm) during test；
C0--- trace gas concentration (vpm) when test is initial；
T --- the testing time (h)；
The gap length of L --- exterior window, m；
V：Room volume, m3。
In Fig. 1, P1~P2 is indoor external differential measuring point, while air parameter is determined, to the interior of small room External differential is measured counting, and it is 0.5m, height to obtain indoor and outdoor the pressure differential deltap P, P1, P2 of small room apart from the distance of window Positioned at the centre position of window.
4) measuring point of Zhongting is arranged, the point layout principle of Zhongting is as follows：
A) exterior window of each direction is both needed to arrange measuring point；
B) exterior window of each floor is both needed to arrange measuring point；
C) height of measuring point is highly identical with the centre position of corresponding exterior window, and indoor and outdoor measuring point and the distance of corresponding exterior window are equal For 0.5m；
Fig. 2 is referred to, Fig. 2 is a longitudinal profile of Architectural Atrium, if Architectural Atrium horizontal section has exterior window, its Point layout principle is identical with longitudinal profile.Wherein 1~2 is the pressure difference measuring point of north orientation, and 3~12 be the pressure difference measuring point of south orientation, often Individual measuring point is 0.5m, is highly located at the centre position of this layer of window apart from the distance of window；
5) the indoor external differential of each measuring point is obtained, and calculates each average pressure difference towards exterior window of acquisition, Δ PE、ΔPW、ΔPS With Δ PNRespectively the four corners of the world to average pressure difference, unit Pa；
6) inleakage of Zhongting exterior window is calculated, formula is as follows：
In formula：
SL --- Zhongting exterior window inleakage, unit m3/h。
In summary, the present invention takes into full account that Zhongting is each towards due to outdoor using the small room of some in building as reference Indoor external differential is inconsistent caused by the difference of wind speed, and measuring point is arranged inside and outside the exterior window of each direction.It is of the invention first Test record first is carried out to each gap length towards exterior window, is then based on above-mentioned measuring point to measure the room corresponding to each direction Inside and outside differential pressure, is finally based on the indoor external differential, the pressure difference of exterior window inleakage and each direction of Zhongting and gap of small room Length, obtains the exterior window inleakage of whole building Zhongting.
According to the present invention it is possible to realize the measure of the large space exterior window inleakage such as Architectural Atrium, it is based on measurement result The inleakage and air-tightness of Architectural Atrium can be evaluated, and further instruct the Remodeling of atrium of next step.
Although the preferred embodiments of the present invention are described above in conjunction with accompanying drawing, the invention is not limited in upper The embodiment stated, above-mentioned embodiment is only schematical, be not it is restricted, this area it is common Technical staff in the case of present inventive concept and scope of the claimed protection is not departed from, may be used also under the enlightenment of the present invention To make many forms, these are belonged within protection scope of the present invention.
