Step 408, B is substituted into the corresponding power-static pressure relation curve formula of preset rotation speed or table, static pressure is calculated
Value C.
Step 410, judge whether C > D is true, if so, thening follow the steps 414；Otherwise, step 412 is executed.Wherein, D is
The nominal static pressure of maximum of air conditioner.
Step 412, display shows the numerical value of C, while showing OK.
Step 414, display shows the numerical value of C, while showing NG.
Specifically, for air pipe type air-conditioner when receiving air hose static pressure detection signal, air supply motor is first in M minutes
With revolving speed A preset in memory module operation, the value range of M is 1 minute~10 minutes, it is preferred that the value of M is 3~5 points
Clock.
Further, power detection module detects the consumption power B of air supply motor automatically；Central processing unit calls the consumption
Power B simultaneously substitutes into power-static pressure relation curve formula or table under the preset rotation speed being fitted in memory module, obtains current
Practical static pressure C.
Further, central processing unit calls in memory module maximum nominal static pressure D and compared with practical static pressure C, if C
≤ D then sends " OK " code to display device；" NG " code is sent if C > D to display device；Display device finally will be practical
Static pressure C and determine come out as the result is shown, it is simple and clear obtain installed air hose whether He Ge conclusion.
Wherein, static pressure detection signal is received in step 402 shown in Fig. 4, by dedicated remote control or line control machine key
It completes, can also be completed by common line control machine or remote controler by combination button.
Step 404 is specially that central processing unit air supply duct formula air conditioner air supply motor sends instruction, with pre- in memory module
If fixed rotating speed A operating.
Step 406 is specially the current consumption power B of power detection module detection air pipe type air-conditioner air supply motor.Detection
Power will carry out after air supply motor was with preset rotation speed A operation M minutes, it is therefore an objective to ensure that motor is stable, the value of M
Range is 1 minute~10 minutes, it is preferred that the value of M is 3~5 minutes.
Step 408 is specially to be fitted in the air pipe type air-conditioner air supply motor power B substitution memory module that will test
Preset rotation speed under power-static pressure relation curve formula or table, obtain currently practical static pressure C；Wherein, under preset rotation speed
Power-static pressure relation curve formula or table, be air supply motor operation memory module in preset revolving speed A when, if by
The corresponding data of dry group static pressure and power is fitted to obtain or directly list obtains.Step 408 is to call power by central processing unit
The testing result of detection module, while power-static pressure relation curve formula or table in memory module are called, by calculating
To currently practical static pressure.For example, static pressure is found through experiments that, and there are as shown in Table 1 corresponding with power as A=1450rpm
Relationship:
| Revolving speed A (rpm) | 1450 | 1450 | 1450 | 1450 | 1450 | 1450 | 1450 | 1450 | 1450 | 1450 | 1450 |
| Static pressure (Pa) | 0 | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 |
| Power (W) | 124 | 118 | 112 | 106 | 98 | 92 | 85 | 79 | 71 | 63 | 55 |
Table 1
According to data shown in table 1, fitting obtains curve shown in fig. 5.Such as when air supply motor is with preset rotation speed A=
When 1450rpm is run, the power of motor B=108W detected, through current static pressure known to table 1 between 20Pa~30Pa,
It can choose nearby principle, i.e. corresponding power 106W when B is close to 30Pa static pressure, it is believed that current static pressure is 30Pa, can also be
Linear interpolation method is selected between 20Pa~30Pa, show that current static pressure is 26.67Pa.More accurate way is by table 1
Data, be fitted by data, obtain power-static pressure relation curve, preferably least square method when preset rotation speed A and be fitted,
Such as the data according to shown in table 1 are fitted to obtain following formula:
Y=-0.0032x2-0.8799x+158.25；
Wherein x is air supply motor power, and y is static pressure.The air supply motor power that will test substitutes into above-mentioned formula, can be straight
It connects and calculates current static pressure, precision is higher.The embodiment of the present invention is not limited to this, such as can be according to air pipe type air-conditioner most
5~100 static pressures divided equally or do not divided equally of setting between big static pressure and 0 static pressure, and obtain 5 by above-mentioned experiment method~
100 groups of power-static pressure corresponding relationship form the parameter table for being similar to table 1 and then obtain corresponding fitting formula.
Step 410 shown in Fig. 4 to step 414 refers to that central processing unit calls maximum nominal static pressure D in memory module
Numerical value, while the practical static pressure C calculated in invocation step 408, compare the size relation of C and D, send if C≤D
" OK " code is to display device；" NG " code is sent if C > D to display device." OK " code indicates the static pressure of installed air hose
Without departing from maximum nominal static pressure, installation qualification；" NG " indicates that the static pressure of installed air hose has exceeded maximum nominal static pressure, peace
It fills unqualified, needs to redesign air hose size or layout.It should be pointed out that " OK " or " NG " code is used only to indicate to sentence
Determine a kind of whether exceeded mark of the above results, other it is any indicate the results codes protection scope of the present invention it
It is interior.
Since display device shows the static pressure C calculated in step 408, while comparison result being shown
Come, to the acceptance of work or the intuitive judgment basis of designer and result.Display device is usually the line traffic control of air pipe type air-conditioner
Device, remote controler or receiving panel etc..
Those skilled in the art is it is to be appreciated that the above embodiment of the present invention is illustrated by taking 1 preset rotation speed as an example
The scheme of detection air conditioner installation specification for 2 or 2 or more preset rotation speeds is equally applicable to above-described embodiment
Technical solution.
Specifically, since when the revolving speed of air supply motor is fixed, with the increase of static pressure, the power of air supply motor can be gradually
Reduce, when static pressure increases to a certain degree, the changing rule that the power of air supply motor changes with static pressure and showed can quilt
It destroys, it is also possible to will lead to power collecting inaccuracy and be unable to satisfy actual requirement.Therefore, when air supply motor is with revolving speed A1 fortune
When row, when the power B1 of air supply motor is less than the comparison power B1 ' stored in memory module, the revolving speed of air supply motor is adjusted to
A2, at this point, if the power B2 of air supply motor is less than the comparison power B2 ' stored in memory module, by the revolving speed of air supply motor
Be adjusted to A3, and continue by the power B3 of air supply motor with stored in memory module correspond to revolving speed A3 compared with power B3 ' into
Row compares, and repeats the above steps, and when air supply motor is with revolving speed An operation, power Bn is greater than or equal to and compares power
When Bn ', Bn is substituted into the power-static pressure relation curve formula or table under the revolving speed An being fitted in memory module, obtains sky
The practical static pressure C of device is adjusted, and then practical static pressure C is compared with the nominal static pressure D of the maximum that memory module stores, with
Comparison result out.
