Fig. 1 is a kind of flow chart of air duct air leak test method according to the ... of the embodiment of the present invention, as shown in Figure 1, this method
Include the following steps：
Step S102 acquires the wind speed that sensor acquires the monitoring point in air duct by wind speed；
Step S104 judges whether air duct leaks out according to wind speed.
Through the above steps, the wind speed that sensor acquires the monitoring point in air duct can be acquired by wind speed；Sentenced according to wind speed
Determine whether air duct leaks out, achieved the purpose that leak out to air duct and detected in time, leak out when air duct can to realize
Effectively to detect the technique effect found in time, and then solves and cause to leak since air duct leakproofness can not be detected in the related technology
Air-conditioning effect caused by wind cannot be found in time is deteriorated, and the technical issues of condensation causes security risk is easy tod produce in refrigeration.
Since the equipment of application is different, the detection whether air duct leaks out may also be specific different, but this hair may be used
Air duct air leak test method described in bright embodiment.In embodiments of the present invention, it is illustrated by taking the air duct of air-conditioning as an example.Air-conditioning
Air duct be pipeline for the outlet air of air conditioner indoor unit being guided to different location in room, what it is due to pipeline transportation is air,
Therefore more demanding to the air-tightness of pipeline, if air duct is leaked out, the air pressure in pipeline can be impacted, to influence wind
Air velocity in road reduces the conevying efficiency in air duct.Even air duct is leaked out, therefore the wind speed in air duct can change, because
This acquires sensor by wind speed and is detected to the wind speed in air duct, and according to the wind speed of detection in embodiments of the present invention
It is compared with the wind speed under the fine status of air duct, to judge whether air duct leaks out, can leak out to air duct timely detection, keep away
Exempted from air duct leak out generation harmful effect and the security risk that subsequently generates.
It should be noted that wind speed acquisition sensor is mounted on the monitoring point in air duct, which can be in air duct
Any point, but in actual monitoring point selection course, the wind speed of the monitoring point will be stablized, which is in air duct position
It is too big that maximum wind velocity and minimum windspeed under the same operation conditions of air-conditioning are unable to deviation.Since the shape in air duct needs basis to build
The actual conditions built are adjusted, therefore when air duct works, some positions in air duct have turbulent flow, are located in turbulent range
The variation of location point wind speed, which more should not acutely be selected, does monitoring point, for example, at duct dimension variation, the corner in air duct etc. is held
The position of turbulent flow easily occurs.In addition, place's monitoring is leaked out accurately in the monitoring point in air duct to the wind upwind road of the monitoring point, it is right
In the wind upwind road of the monitoring point, the leak out accuracy rate of place's monitoring substantially reduces, therefore in the present embodiment, monitoring point it is upper
Wind direction, which leaks out, to be detected, the lower wind direction of monitoring point, which leaks out, to be needed to set up other monitoring point and go to detect.
Judge whether air duct leaks out according to wind speed, can be various ways, the detection wind speed of monitoring point and this can be passed through
Wind speed of the monitoring point in the case where air duct is intact directly compares, if detection wind speed exceeds the threshold value of the wind speed, judges the inspection
It is wind speed caused by leaking out to survey wind speed, but the threshold value of the method generally requires a large amount of experimental data, and wind speed by shadow
The factor of sound is more, often there is larger unstability.Therefore in the present embodiment, it is preferred that whether judge air duct according to wind speed
Leak out including：The sea land distribution ratio of monitoring point is determined according to wind speed；In sea land distribution ratio of the sea land distribution than exceeding monitoring point
In the case of threshold value, determine that air duct is leaked out.
It should be noted that sea land distribution ratio X=(Vi-Vn)/Vi* 100%, wherein ViFor develop design when, in wind
The design wind speed that air-conditioning different mode, different wind shelves air outlet wind speed are tested, demarcated under road sealing serviceable condition, VnFor
The air outlet wind speed of acquisition.It is detected using sea land distribution ratio, is detected compared to using wind speed, detection robustness is apparent
It improves, reduces the error rate of detection.
Optionally, monitoring site is at the air outlet position in air duct.
It should be noted that the position of the monitoring point can be any position in air duct, and in the present embodiment, the monitoring point
At the air outlet position in air duct, not only facilitate repair, but also any position in entire air duct is leaked out, air duct outlet air
The wind speed of mouth can all change, and the air outlet that monitoring point is arranged in air duct can be monitored entire air duct, greatly
Reduce cost.
Optionally, according to wind speed judge air duct whether leak out including：In the case where the number of monitoring point is multiple, according to
Whether leak out in the wind speed judgement air duct of multiple monitoring points.
It should be noted that in the case where air duct is longer and/or air channel structure is complicated, only it is arranged in the air outlet in air duct
Monitoring point is the situation of leaking out that can not accurately detect entire air duct.Therefore longer and/or air channel structure is complicated in air duct
In the case of, the present embodiment in air duct using multiple monitoring points are arranged, if air duct is divided into stem portion by multiple monitoring points,
Not only leaking out for the various pieces in air duct can accurately be detected, greatly promote the accuracy rate for detecting situation of leaking out, and
And can be as accurate as leaking out and a little be located near which monitoring point, it constructs convenient for later period maintenance, effectively promotes the maintenance construction to leak out
Efficiency.It should be noted that the set-up mode of multiple monitoring points can be diversified forms, can be generally evenly distributed in air duct it
In, it can also be the specific trend according to air duct, determine the position of monitoring point, it mainly will be complicated superfluous by the laying of monitoring point
Long air duct is divided into several detection sections for facilitating detection, leaks out a little convenient for detection, improves the accuracy rate that detection is leaked out.
Optionally, according to the wind speed of multiple monitoring points judge air duct whether leak out including：At least one in multiple monitoring points
The sea land distribution ratio of a monitoring point be more than sea land distribution than threshold value in the case of, determine that air duct is leaked out；Determining that air duct leaks out it
Afterwards, further include：According to the sea land distribution of multiple monitoring points than judging a position of leaking out, wherein point of leaking out declines setting in wind speed
Subtract than being differed between the adjacent monitoring point in maximum monitoring point and monitoring point than threshold value with sea land distribution.
When it is implemented, the sea land distribution ratio of at least one monitoring point compares threshold value more than sea land distribution in multiple monitoring points
In the case of, determine that air duct is leaked out, some leaks out situation since inleakage is larger or the building mouth that leaks out is special (for example, long gap-like
Leak out mouth) the sea land distribution ratio of multiple monitoring points may be caused to change, but ordinary circumstance is all to cause this to leak out under place
First monitoring point wind speed of wind direction changes, and in the simple air duct of framework, all monitorings of wind direction under the mouth that leaks out
Point can all change, but in the complicated and longer air duct of length, the wind of at least one monitoring point after generation of leaking out
Fast attenuation ratio meeting superthreshold, as long as therefore it is more than the case where sea land distribution is than threshold value to have the sea land distribution ratio of any one monitoring point
Under, it can determine that air duct is leaked out.
Judge a position of leaking out according further to the sea land distribution ratio of multiple monitoring points, the position estimating of monitoring point can be passed through
The position leaked out a little, this leaks out the affirmative of position a little near monitoring point, if only there are one the sea land distributions of monitoring point than super
Sea land distribution is crossed than threshold value, then this leaks out range a little between two adjacent monitoring points of the test point, if there are multiple prisons
For the sea land distribution ratio of measuring point more than sea land distribution than threshold value, then point of leaking out compares threshold value setting in sea land distribution ratio and sea land distribution
It differs between the monitoring point adjacent with monitoring point of maximum monitoring point.
Optionally, in the case where sea land distribution is than exceeding the sea land distribution of monitoring point than threshold value, determine that air duct is leaked out
Before, further include：In the state that air duct seals, the wind speed that monitoring point is under the predetermined running pattern of air duct corresponding device
It is measured, obtains measurement result；According to measurement result, determine that design wind speed and sea land distribution compare threshold value, wherein design wind
Speed is for determining sea land distribution ratio.
It should be noted that in the case where sea land distribution is than exceeding the sea land distribution of monitoring point than threshold value, wind is determined
Before road leaks out, need that sea land distribution is monitored and is determined than therewith, the air duct of different length and shape is in different mode
The degree of the sea land distribution of lower generation is different, therefore for the monitoring point in a completely new air duct or new position, is needed
First the sea land distribution threshold value under the different mode of the test point is detected and is recorded, could be used to leak out progress to air duct
Detection.
Optionally, after determining that air duct is leaked out, further include：Transmission is used to indicate the alarm command that air duct is leaked out, wherein
Alarm command includes the air duct parameter leaked out, wherein air duct parameter is for formulating solution of leaking out.
After determining that air duct is leaked out, needs to notify user or operating personnel, be generally used the mode of alarm, pass through control
Device processed sends alarm command, so that warning device is worked, to notify user, it should be noted that the mode of alarm can
It to take alarm, makes a sound, sends out the modes such as light, it can also be short by being sent to the remote port of user operating personnel
Letter, the modes such as information notify user or operating personnel.
Optionally, after determining that air duct is leaked out, further include：Judge whether air duct corresponding device is in refrigeration mode；
Judging result is in the case of being, control air duct corresponding device turns air supply pattern.
Need to illustrate still, after determining that air duct is leaked out, need to leak out there may be or caused security risk into
Row prevents, such as in the case where air-conditioning belongs to refrigeration mode, air duct, which is leaked out, easy tos produce dew condensation phenomenon, so as to cause line is increased
The possibility of road conduction, thus detect leak out after the refrigeration mode of air-conditioning is automatically converted to air supply pattern, not only effectively
It prevents security risk and can alarm in this way to user.
