Specifically, air pipe type air-conditioner when receiving airduct static pressure detection signal, air supply motor first in M minute with memory module in preset rotating speed A run, the span of M is 1 minute ~ 10 minutes, and preferably, the value of M is 3 ~ 5 minutes.
Further, power detection module detects the consumed power B of air supply motor automatically; Central processing unit calls this consumed power B and power-static pressure relation curve formula under substituting into the preset rotation speed that in memory module, matching is good or form, obtains current actual static pressure C.
Further, central processing unit calls maximum nominal static pressure D in memory module and compares with actual static pressure C, if C≤D, sends " OK " code to display unit; If C>D, send " NG " code to display unit; Display unit actual static pressure C and result of determination shows, and simple and clearly draws the conclusion whether installed airduct is qualified.
Wherein, in the step 402 shown in Fig. 4, receive static pressure detection signal, completed by dedicated remote control or line control machine button, also can be completed by combination button by common line control machine or remote controller.
Step 404 is specially central processing unit and sends instruction to air pipe type air-conditioner air supply motor, operates with the fixed rotating speed A preset in memory module.
Step 406 is specially power detection module and detects the current consumed power B of air pipe type air-conditioner air supply motor.Detection power will be carried out after air supply motor runs M minute with preset rotation speed A, and object guarantees that motor is stable, and the span of M is 1 minute ~ 10 minutes, and preferably, the value of M is 3 ~ 5 minutes.
Step 408 is specially and the air pipe type air-conditioner air supply motor power B that detects is substituted into power-static pressure relation curve formula under the preset rotation speed that in memory module, matching is good or form, obtains current actual static pressure C; Wherein, the power under preset rotation speed-static pressure relation curve formula or form are when air supply motor runs the rotating speed A preset in memory module, are obtained or directly list draws by the corresponding data matching of some groups of static pressure and power.Step 408 is called the testing result of power detection module, calls the power-static pressure relation curve formula in memory module or form simultaneously, by calculating current actual static pressure.Such as, as A=1450rpm, found through experiments static pressure and power exists corresponding relation as shown in table 1:
| Rotating 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 the data shown in table 1, matching obtains the curve shown in Fig. 5.Such as when air supply motor runs with preset rotation speed A=1450rpm, the power of motor B=108W detected, by the known current static pressure of table 1 between 20Pa ~ 30Pa, nearby principle can be selected, namely the power 106W that B is corresponding when 30Pa static pressure, think that current static pressure is 30Pa, also can between 20Pa ~ 30Pa select linear interpolation method, show that current static pressure is 26.67Pa.More accurate way is by the data in table 1, by data fitting, and power-static pressure relation curve when obtaining preset rotation speed A, preferred least square method carries out matching, such as, obtain following formula according to the data fitting shown in table 1:
y＝-0.0032x
2-0.8799x+158.25；
Wherein x is air supply motor power, and y is static pressure.The air supply motor power detected is substituted into above-mentioned formula, and can directly calculate current static pressure, precision is higher.Embodiments of the invention are not limited to this, such as can according to arranging 5 ~ 100 static pressures divided equally or do not divide equally between the maximum static pressure of air pipe type air-conditioner and 0 static pressure, and obtaining 5 ~ 100 groups of power-static pressure corresponding relation by above-mentioned experiment method, formation is similar to the parameter form of table 1 and then draws corresponding fitting formula.
Step 410 shown in Fig. 4 to step 414 refers to that central processing unit calls the numerical value of maximum nominal static pressure D in memory module, the actual static pressure C simultaneously calculated in invocation step 408, relatively the magnitude relationship of C and D, if C≤D, sends " OK " code to display unit; If C>D, send " NG " code to display unit." OK " coded representation airduct is installed static pressure do not exceed maximum nominal static pressure, installation qualification; " NG " represents that the static pressure that airduct is installed by institute has exceeded maximum nominal static pressure, installs defective, needs redesign airduct size or layout.It should be pointed out that " OK " or " NG " code is only used to represent the one mark judging whether the above results exceeds standard, the code of other any these results of expression is all within protection scope of the present invention.
Because the static pressure C calculated in step 408 shows by display unit, comparative result is shown, to the acceptance of work or designer's basis for estimation and result intuitively simultaneously.Display unit is generally line control machine, the remote controller or receiving panel etc. of air pipe type air-conditioner.
Those skilled in the art, it is to be appreciated that the above embodiment of the present invention has set forth for 1 preset rotation speed the scheme detecting air-conditioner installation specification, for more than 2 or 2 preset rotation speed, is equally applicable to the technical scheme of above-described embodiment.
Particularly, due to when the rotating speed of air supply motor is fixed, along with the increase of static pressure, the power of air supply motor can reduce gradually, when static pressure increases to a certain degree, the Changing Pattern that the power of air supply motor shows with static pressure change can be destroyed, and power collecting also likely can be caused inaccurate and cannot meet actual requirement.Therefore, when air supply motor runs with rotating speed A1, when the power B1 of air supply motor is less than the comparison power B1 ' stored in memory module, the rotating speed of air supply motor is adjusted to A2, now, if the power B2 of air supply motor is less than the comparison power B2 ' stored in memory module, then the rotating speed of air supply motor is adjusted to A3, and continue the power B3 of air supply motor to compare with the power B3 ' that compares corresponding to rotating speed A3 stored in memory module, and repeat above-mentioned steps, until when air supply motor runs with rotating speed An, its power Bn is more than or equal to when comparing power Bn ', Bn is substituted into the power-static pressure relation curve formula under the good rotating speed An of matching in memory module or form, obtain the actual static pressure C of air-conditioner, and then the maximum nominal static pressure D actual static pressure C and memory module to be stored compares, to draw comparative result.
More than be described with reference to the accompanying drawings technical scheme of the present invention, the present invention proposes a kind of scheme of detection air-conditioner installation specification newly, the actual static pressure of air-conditioner can be detected exactly, so can accurately judge air-conditioner airduct is installed actual static pressure whether meet specification.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
