Description

检测空调器安装规范性的方法、装置和空调器Method, device and air conditioner for detecting air conditioner installation norm 技术领域Technical field
本发明涉及空调器技术领域，具体而言，涉及一种检测空调器安装规范性的方法、一种检测空调器安装规范性的装置和一种空调器。The present invention relates to the technical field of air conditioners, and in particular to a method for detecting the installation norm of an air conditioner, a device for detecting the installation norm of an air conditioner, and an air conditioner.
背景技术Background technique
风管式空调器主要应用在楼宇工程领域，大部分是通过安装风管将空调器出风输送到需要的位置。通常情况下，空调器生产厂家会针对产品的性能，给出最大标称静压，如果实际安装的风管选型不合适，可能会超出最大标称静压，导致出风量偏小、输出制冷量和制热量不足的问题，进而影响房间舒适性。因此，判断风管选型是否合适，在工程验收环节尤为重要。Duct air conditioners are mainly used in the field of building engineering. Most of them are installed by air ducts to transport air conditioners to the required locations. Normally, the air conditioner manufacturer will give the maximum nominal static pressure for the performance of the product. If the actual installed air duct is not properly selected, it may exceed the maximum nominal static pressure, resulting in a small air volume and output cooling. The problem of insufficient quantity and heat production, which in turn affects the comfort of the room. Therefore, judging whether the selection of the duct is appropriate is particularly important in the project acceptance.
目前，判断风管选型是否合适的做法一般是根据经验公式计算风管静压，但是这种方法精确度不高，尤其是计算结果和最大标称静压接近时，很难做出最终的判断。还有的做法是在安装完成后，检测出风口的风速来进行判断，这种方法可以在一定程度上对风管安装的合理性做出判断，但是由于受到出风口风速分布不均匀的影响，同样难以进行精确判定。At present, the judgment of whether the selection of the duct is appropriate is generally based on the empirical formula to calculate the static pressure of the duct, but the accuracy of this method is not high, especially when the calculation result and the maximum nominal static pressure are close, it is difficult to make the final Judge. Another method is to detect the wind speed of the tuyere after the installation is completed. This method can judge the rationality of the installation of the duct to a certain extent, but due to the uneven distribution of the wind speed of the outlet, It is also difficult to make an accurate decision.
因此，如何能够使工程人员直观地确定空调器所安装风管的实际静压是否符合规范成为亟待解决的技术问题。Therefore, how to enable the engineer to intuitively determine whether the actual static pressure of the air duct installed in the air conditioner conforms to the specification has become a technical problem to be solved.

为此，本发明的一个目的在于提出了一种新的检测空调器安装规范性的方案，使得工程人员能够直观地确定空调器所安装风管的实际静压是否符合规范，极大地方便了工程人员的验收过程。To this end, an object of the present invention is to propose a new scheme for detecting the installation of air conditioners, so that the engineer can intuitively determine whether the actual static pressure of the air duct installed in the air conditioner conforms to the specifications, which greatly facilitates the engineering.

Wherein, the manner of prompting the user whether the air conditioner is installed with the specification may be a manner of displaying and/or broadcasting by means of display. The designated mode may be an existing mode of the air conditioner, such as a cooling mode, a heating mode, or the like, or may be a new mode defined to detect the air conditioner installation normability.
根据本发明的上述实施例的检测空调器安装规范性的方法，还可以具有以下技术特征：According to the above embodiment of the present invention, the method of detecting the air conditioner installation normability may further have the following technical features:
根据本发明的一个实施例，根据所述实际静压与所述空调器的最大标称静压，确定所述空调器是否安装规范的步骤，具体包括：在所述实际静压大于所述空调器的最大标称静压时，确定所述空调器安装不规范；在所述实际静压小于或等于所述空调器的最大标称静压时，确定所述空调器安装规范。According to an embodiment of the present invention, the step of determining whether the air conditioner is installed with a specification according to the actual static pressure and the maximum nominal static pressure of the air conditioner, specifically comprising: the actual static pressure is greater than the air conditioner When the maximum nominal static pressure of the device is determined, it is determined that the air conditioner is not installed properly; and when the actual static pressure is less than or equal to the maximum nominal static pressure of the air conditioner, the air conditioner installation specification is determined.
根据本发明的一个实施例，检测所述空调器当前的实际静压的步骤，具体包括：控制所述空调器的送风电机以预设转速运行；检测所述送风电机的当前功率，并判断所述送风电机的当前功率是否大于或等于与所述预设转速相对应的预定功率值；在判定所述送风电机的当前功率大于或等于与所述预设转速相对应的预定功率值时，根据所述预设转速和所述当前功率确定所述空调器当前的实际静压；在判定所述送风电机的当前功率小于与所述预设转速相对应的预定功率值时，逐步改变所述送风电机的转速，直到所述送风电机的当前功率大于或等于与所述送风电机的当前转速相对应的预定功率值；在所述送风电机的当前功率大于或等于与所述送风电机 的当前转速相对应的预定功率值时，根据所述送风电机的当前转速和当前功率确定所述空调器当前的实际静压。According to an embodiment of the present invention, the step of detecting the current actual static pressure of the air conditioner specifically includes: controlling a blower motor of the air conditioner to operate at a preset speed; detecting a current power of the blower motor, and Determining whether the current power of the blower motor is greater than or equal to a predetermined power value corresponding to the preset speed; determining that the current power of the blower motor is greater than or equal to a predetermined power corresponding to the preset speed And determining, according to the preset rotation speed and the current power, an actual static pressure of the air conditioner; and determining that the current power of the air supply motor is less than a predetermined power value corresponding to the preset rotation speed, Stepwise changing the rotational speed of the blower motor until the current power of the blower motor is greater than or equal to a predetermined power value corresponding to the current rotational speed of the blower motor; the current power of the blower motor is greater than or equal to And the blower motor When the current rotational speed corresponds to a predetermined power value, the current actual static pressure of the air conditioner is determined according to the current rotational speed of the air supply motor and the current power.
根据本发明的实施例的检测空调器安装规范性的方法，由于在送风电机的转速固定时，随着静压的增大，送风电机的功率会逐渐减小，当静压增大至一定程度时，送风电机的功率随静压变化而表现出来的变化规律会被破坏，也有可能会导致功率采集不准确而无法满足实际要求。因此，当送风电机以预设转速运行时，若送风电机的当前功率小于与预设转速相对应的预定功率值，则可以通过改变送风电机的转速，以使送风电机的当前功率大于或等于与送风电机的当前转速相对应的预定功率值，进而能够确保根据送风电机的当前转速和当前功率计算出的实际静压具有更高的精度，从而能够准确判断空调器所安装风管的实际静压是否符合规范。According to an embodiment of the present invention, a method for detecting the installation accuracy of an air conditioner is provided. When the rotational speed of the blower motor is fixed, as the static pressure increases, the power of the blower motor gradually decreases, and when the static pressure increases to To a certain extent, the variation of the power of the air supply motor as a function of static pressure will be destroyed, and the power collection may be inaccurate and cannot meet the actual requirements. Therefore, when the blower motor runs at the preset speed, if the current power of the blower motor is less than the predetermined power value corresponding to the preset speed, the current power of the blower motor can be changed by changing the speed of the blower motor. It is greater than or equal to a predetermined power value corresponding to the current rotational speed of the blower motor, thereby ensuring higher accuracy of the actual static pressure calculated according to the current rotational speed of the blower motor and the current power, thereby accurately determining the installation of the air conditioner.

方案一：通过检测送风电机的功率来检测空调器的实际静压。Solution 1: The actual static pressure of the air conditioner is detected by detecting the power of the air supply motor.
具体地，检测所述空调器当前的实际静压的步骤，具体包括：控制所述空调器的送风电机以预设转速运行；检测所述送风电机的当前功率，并判断所述送风电机的当前功率是否大于或等于与所述预设转速相对应的预定功率值；在判定所述送风电机的当前功率大于或等于与所述预设转速相对应的预定功率值时，根据所述预设转速和所述当前功率确定所述空调器当前的实际静压；在判定所述送风电机的当前功率小于与所述预设转速相对应的预定功率值时，逐步改变所述送风电机的转速，直到所述送风电机的当前功率大于或等于与所述送风电机的当前转速相对应的预定功率值；在所述送风电机的当前功率大于或等于与所述送风电机的当前转速相对应的预定功率值时，根据所述送风电机的当前转速和当前功率确定所述空调器当前的实际静压。Specifically, the step of detecting the current actual static pressure of the air conditioner specifically includes: controlling a blower motor of the air conditioner to operate at a preset speed; detecting a current power of the air blower motor, and determining the air supply Whether the current power of the motor is greater than or equal to a predetermined power value corresponding to the preset rotation speed; when it is determined that the current power of the air supply motor is greater than or equal to a predetermined power value corresponding to the preset rotation speed, Determining a current actual static pressure of the air conditioner according to the preset rotation speed and the current power; and gradually changing the delivery when determining that the current power of the air supply motor is less than a predetermined power value corresponding to the preset rotation speed The rotational speed of the wind motor until the current power of the blower motor is greater than or equal to a predetermined power value corresponding to the current rotational speed of the blower motor; the current power of the blower motor is greater than or equal to the air supply When the current rotational speed of the motor corresponds to a predetermined power value, the current actual static pressure of the air conditioner is determined according to the current rotational speed of the air supply motor and the current power.
由于在送风电机的转速固定时，随着静压的增大，送风电机的功率会 逐渐减小，当静压增大至一定程度时，送风电机的功率随静压变化而表现出来的变化规律会被破坏，也有可能会导致功率采集不准确而无法满足实际要求。因此，当送风电机以预设转速运行时，若送风电机的当前功率小于与预设转速相对应的预定功率值，则可以通过改变送风电机的转速，以使送风电机的当前功率大于或等于与送风电机的当前转速相对应的预定功率值，进而能够确保根据送风电机的当前转速和当前功率计算出的实际静压具有更高的精度，从而能够准确判断空调器所安装风管的实际静压是否符合规范。Since the static pressure increases as the speed of the blower motor is fixed, the power of the blower motor will Gradually decrease, when the static pressure increases to a certain extent, the variation of the power of the air supply motor as a function of static pressure will be destroyed, and the power collection may be inaccurate and cannot meet the actual requirements. Therefore, when the blower motor runs at the preset speed, if the current power of the blower motor is less than the predetermined power value corresponding to the preset speed, the current power of the blower motor can be changed by changing the speed of the blower motor. It is greater than or equal to a predetermined power value corresponding to the current rotational speed of the blower motor, thereby ensuring higher accuracy of the actual static pressure calculated according to the current rotational speed of the blower motor and the current power, thereby accurately determining the installation of the air conditioner. Whether the actual static pressure of the air duct meets the specifications.
根据本发明的一个实施例，根据所述送风电机的当前转速和当前功率确定所述空调器当前的实际静压的步骤，具体包括：根据所述送风电机的当前功率，以及对应于所述当前转速的功率与静压的关系，确定所述空调器当前的实际静压。According to an embodiment of the present invention, the step of determining the current actual static pressure of the air conditioner according to the current rotational speed and the current power of the air supply motor specifically includes: according to the current power of the air supply motor, and corresponding to the The relationship between the power of the current rotational speed and the static pressure is determined, and the current actual static pressure of the air conditioner is determined.
其中，功率与静压的关系可以通过以下方式确定：在送风电机以所述当前转速运行时，检测送风电机在多个不同静压中每个静压条件下的功率，进而对多个不同静压与检测的每个静压条件下送风电机的功率进行拟合，以得到功率与静压的关系曲线，或者直接得到相应的对应列表。Wherein, the relationship between the power and the static pressure can be determined by: when the blower motor is operated at the current speed, detecting the power of the blower motor under each static pressure condition of the plurality of different static pressures, and then Different static pressures are fitted to the power of the blower motor under each static pressure condition to obtain a relationship between power and static pressure, or directly obtain a corresponding corresponding list.
方案二：通过检测送风电机的工作电流来检测空调器的实际静压。Option 2: Detect the actual static pressure of the air conditioner by detecting the operating current of the air supply motor.
具体地，检测所述空调器当前的实际静压的步骤，具体包括：控制所述空调器的送风电机以预设转速运行；检测所述送风电机的当前工作电流，并判断所述送风电机的当前工作电流是否大于或等于与所述预设转速相对应的预定电流值；在判定所述送风电机的当前工作电流大于或等于与所述预设转速相对应的预定电流值时，根据所述预设转速和所述当前工作电流确定所述空调器当前的实际静压；在判定所述送风电机的当前工作电流小于与所述预设转速相对应的预定电流值时，逐步改变所述送风电机的转速，直到所述送风电机的当前工作电流大于或等于与所述送风电机的当前转速相对应的预定电流值；在所述送风电机的当前工作电流大于或等于与所述送风电机的当前转速相对应的预定电流值时，根据所述送风电机的当前转速和当前工作电流确定所述空调器当前的实际静压。Specifically, the step of detecting the current actual static pressure of the air conditioner specifically includes: controlling a blower motor of the air conditioner to operate at a preset speed; detecting a current working current of the air blower motor, and determining the sending Whether the current operating current of the wind motor is greater than or equal to a predetermined current value corresponding to the preset rotational speed; when it is determined that the current operating current of the air supplying motor is greater than or equal to a predetermined current value corresponding to the preset rotational speed Determining a current actual static pressure of the air conditioner according to the preset rotation speed and the current working current; and determining that a current operating current of the air supply motor is less than a predetermined current value corresponding to the preset rotation speed, Stepwise changing the rotational speed of the air supply motor until the current operating current of the air supply motor is greater than or equal to a predetermined current value corresponding to the current rotational speed of the air supply motor; the current operating current of the air supply motor is greater than Or equal to a predetermined current value corresponding to the current rotational speed of the air supply motor, determining the air according to the current rotational speed of the air supply motor and the current operating current It is the current actual static pressure.
由于在送风电机的转速固定时，随着静压的增大，送风电机的工作电流会逐渐减小，当静压增大至一定程度时，送风电机的工作电流随静压变 化而表现出来的变化规律会被破坏，也有可能会导致工作电流采集不准确而无法满足实际要求。因此，当送风电机以预设转速运行时，若送风电机的当前工作电流小于与预设转速相对应的预定电流值，则可以通过改变送风电机的转速，以使送风电机的当前工作电流大于或等于与送风电机的当前转速相对应的预定电流值，进而能够确保根据送风电机的当前转速和当前工作电流计算出的实际静压具有更高的精度，从而能够准确判断空调器所安装风管的实际静压是否符合规范。Since the operating current of the blower motor gradually decreases as the static pressure increases when the rotational speed of the blower motor is fixed, the operating current of the blower motor changes with the static pressure when the static pressure increases to a certain extent. The changing laws that are manifested by the transformation will be destroyed, and the working current collection may be inaccurate and cannot meet the actual requirements. Therefore, when the blower motor runs at the preset speed, if the current operating current of the blower motor is less than a predetermined current value corresponding to the preset speed, the current speed of the blower motor can be changed to make the current of the blower motor The working current is greater than or equal to a predetermined current value corresponding to the current rotational speed of the blower motor, thereby ensuring higher accuracy of the actual static pressure calculated according to the current rotational speed of the blower motor and the current operating current, thereby accurately determining the air conditioner Whether the actual static pressure of the air duct installed is in compliance with the specifications.

方案三：third solution:

步骤414，显示器显示C的数值，同时显示NG。In step 414, the display displays the value of C while displaying NG.
其中，空调器是风管式空调器，风管式空调器在接收到风管静压检测信号时，送风电机首先在M分钟内以存储模块304中预设的转速A运行，M的取值范围是1分钟～10分钟，优选的，M的取值为3～5分钟。Wherein, the air conditioner is a duct type air conditioner, and when the duct type air conditioner receives the air duct static pressure detection signal, the air supply motor first runs in the M minute at a preset speed A in the storage module 304, and the M is taken. The value ranges from 1 minute to 10 minutes. Preferably, the value of M is 3 to 5 minutes.
进一步的，功率采集模块302自动检测送风电机的消耗功率B；中央处理器306调用该消耗功率B并代入存储模块304中拟合好的预设转速下的功率-静压关系曲线公式或表格，得到当前实际静压值C。Further, the power collection module 302 automatically detects the power consumption B of the air supply motor; the central processor 306 calls the power consumption B and substitutes the power-static pressure relationship curve formula or table at the preset rotation speed fitted in the storage module 304. , get the current actual static pressure value C.
进一步的，中央处理器306调用存储模块304中最大标称静压D并与实际静压值C比较，若C≤D则发送“OK”代码给显示装置308；若C>D则发送“NG”代码给显示装置308；显示装置308最终将实际静压值C和判定结果显示出来，简单明了得出所安装风管是否合格的结论。Further, the central processing unit 306 calls the maximum nominal static pressure D in the storage module 304 and compares it with the actual static pressure value C. If C≤D, an "OK" code is sent to the display device 308; if C>D, the "NG" is sent. The code is given to the display device 308; the display device 308 finally displays the actual static pressure value C and the determination result, and simply concludes that the installed air duct is qualified.
其中，图4中所示的步骤402中接收到静压检测信号，由专用遥控器或线控器按键完成，也可由普通线控器或遥控器通过组合按键完成。Wherein, the static pressure detection signal is received in step 402 shown in FIG. 4, and is completed by a dedicated remote controller or a line controller button, and can also be completed by a combination of a common line controller or a remote controller.
步骤404具体为中央处理器306给风管式空调器送风电机发送指令，以存储模块304中预设的固定转速A运转。Step 404 is specifically that the central processing unit 306 sends an instruction to the air duct air conditioner air supply motor to operate at a fixed rotation speed A preset in the storage module 304.
步骤406具体为功率采集模块302检测风管式空调器送风电机当前的消耗功率B。检测功率要在送风电机以预设转速A运行M分钟后进行，目的是确保电机已经运行稳定，M的取值范围是1分钟～10分钟，优选的，M的取值为3～5分钟。Step 406 is specifically for the power collection module 302 to detect the current power consumption B of the air duct air conditioner. The detection power is to be performed after the air supply motor is operated at the preset speed A for M minutes. The purpose is to ensure that the motor has been running stably. The value of M ranges from 1 minute to 10 minutes. Preferably, the value of M is 3 to 5 minutes. .
步骤408具体为将检测到的风管式空调器送风电机功率B代入存储模块304中拟合好的预设转速下的功率-静压关系曲线公式或表格，得到当前实际静压值C；其中，预设转速下的功率-静压关系曲线公式或表格，是在送风电机运行存储模块304中预设的转速A时，通过若干组静压和功率的对应数据拟合得到或直接列表得出。步骤408是由中央处理器306调 用功率采集模块302的检测结果，同时调用存储模块304中的功率-静压关系曲线公式或表格，通过计算得到当前实际静压。例如，当A＝1450rpm时，通过实验发现静压与功率存在如表1所示的对应关系：Step 408 is specifically to replace the detected duct air conditioner air supply motor power B into the power-static pressure relationship curve formula or table in the storage module 304 at a preset preset speed to obtain the current actual static pressure value C; Wherein, the power-static pressure relationship curve formula or table at the preset speed is obtained by fitting or directly listing the corresponding data of the static pressure and the power when the preset speed A is set in the air supply motor running storage module 304. inferred. Step 408 is adjusted by the central processing unit 306. Using the detection result of the power collection module 302, the power-static pressure relationship curve formula or table in the storage module 304 is simultaneously called, and the current actual static pressure is obtained by calculation. For example, when A=1450rpm, it is found through experiments that the static pressure and power have the corresponding relationship as shown in Table 1:
转速A(rpm)Speed A (rpm) 14501450 14501450 14501450 14501450 14501450 14501450 14501450 14501450 14501450 14501450 14501450
静压(Pa)Static pressure (Pa) 00 1010 2020 3030 4040 5050 6060 7070 8080 9090 100100
功率(W)Power (W) 124124 118118 112112 106106 9898 9292 8585 7979 7171 6363 5555
表1Table 1
根据表1中所示的数据，拟合得到图5所示的曲线。例如当送风电机以预设转速A＝1450rpm运行时，检测到的电机功率B＝108W，通过表1可知当前静压值在20Pa～30Pa之间，可以选择就近原则，即B靠近30Pa静压时对应的功率106W，认为当前静压是30Pa，也可以在20Pa～30Pa之间选择线性插值法，得出当前静压值为26.67Pa。更精确的做法是基于表1中的数据，通过数据拟合，得到预设转速A时功率-静压关系曲线，优选最小二乘法进行拟合，例如根据表1中所示的数据拟合得到下述公式：According to the data shown in Table 1, the curve shown in Fig. 5 was obtained. For example, when the air supply motor is running at the preset speed A=1450rpm, the detected motor power B=108W. It can be seen from Table 1 that the current static pressure value is between 20Pa and 30Pa, and the principle of proximity can be selected, that is, B is close to 30Pa static pressure. When the corresponding power is 106W, it is considered that the current static pressure is 30Pa, and the linear interpolation method can be selected between 20Pa and 30Pa, and the current static pressure value is 26.67Pa. More precisely, based on the data in Table 1, by data fitting, the power-static pressure relationship curve at the preset speed A is obtained, preferably by least squares fitting, for example, according to the data fitting shown in Table 1. The following formula:
y＝-0.0032x2-0.8799x+158.25y=-0.0032x 2 -0.8799x+158.25
其中，x为送风电机功率，y为静压值。将检测到的送风电机功率代入上述公式，可直接算出当前静压值，精度更高。Where x is the power of the blower motor and y is the static pressure value. Substituting the detected power of the blower motor into the above formula, the current static pressure value can be directly calculated, and the accuracy is higher.
本发明的实施例并不限于此，例如可根据风管式空调器的最大静压与0静压之间设置5～100个均分或不均分的静压值，并通过上述实验方式得到5～100组功率-静压对应关系，形成类似于表1的参数表格进而得出相应的拟合公式。The embodiment of the present invention is not limited thereto. For example, a static pressure value of 5 to 100 equalization or unevenness may be set according to the maximum static pressure and the zero static pressure of the air duct type air conditioner, and obtained by the above experimental method. 5 to 100 sets of power-static pressure correspondence, forming a parameter table similar to Table 1 to obtain the corresponding fitting formula.
图4所示的步骤410至步骤414是指中央处理器306调用存储模块304中最大标称静压D的数值，同时调用步骤408中计算出来的实际静压值C，比较C和D的大小关系，若C≤D则发送“OK”代码给显示装置308；若C>D则发送“NG”代码给显示装置308。“OK”代码表示所安装风管的静压没有超出最大标称静压，安装合格；“NG”表示所安装风管的静压已经超出最大标称静压，安装不合格，需要重新设计风管尺寸或布局。应当指出的是，“OK”或“NG”代码只是用来表示判定上述结果是否超标的一种标志，其他任何表示该结果的代码均在本发明的保护范围 之内。 Steps 410 to 414 shown in FIG. 4 refer to the central processor 306 calling the value of the maximum nominal static pressure D in the storage module 304, and simultaneously calling the actual static pressure value C calculated in step 408, and comparing the sizes of C and D. The relationship, if C ≤ D, sends an "OK" code to display device 308; if C > D, an "NG" code is sent to display device 308. The “OK” code indicates that the static pressure of the installed duct does not exceed the maximum nominal static pressure, and the installation is qualified; “NG” indicates that the static pressure of the installed duct has exceeded the maximum nominal static pressure, the installation is unqualified, and the wind needs to be redesigned. Tube size or layout. It should be noted that the "OK" or "NG" code is only a sign indicating whether the above result is exceeded, and any other code indicating the result is within the scope of the present invention. within.
由于显示装置308将步骤408中计算出来的静压值C显示出来，同时将比较结果显示出来，给工程验收或设计人员直观的判断依据和结果。显示装置308通常为风管式空调器的线控器、遥控器或接收面板等。Since the display device 308 displays the static pressure value C calculated in step 408 and displays the comparison result, the engineering acceptance or the designer intuitively judges the basis and the result. The display device 308 is typically a wire controller, a remote control, or a receiving panel of a ducted air conditioner.
本领域的技术人员需要理解的是，该实施例以1个预设转速为例阐述了检测空调器安装规范性的方案，对于2个或2个以上的预设转速，同样适用于上述实施例的技术方案。It should be understood by those skilled in the art that the embodiment illustrates a scheme for detecting the installation accuracy of the air conditioner by taking one preset rotation speed as an example. For two or more preset rotation speeds, the same applies to the above embodiment. Technical solution.
具体地，由于在送风电机的转速固定时，随着静压的增大，送风电机的功率会逐渐减小，当静压增大至一定程度时，送风电机的功率随静压变化而表现出来的变化规律会被破坏，也有可能会导致功率采集不准确而无法满足实际要求。因此，当送风电机以转速A1运行时，送风电机的功率B1小于存储模块304中存储的比较功率B1’时，将送风电机的转速调为A2，此时，若送风电机的功率B2小于存储模块304中存储的比较功率B2’，则将送风电机的转速调为A3，并继续将送风电机的功率B3与存储模块304中存储的对应于转速A3的比较功率B3’进行比较，并重复上述步骤，直到送风电机以转速An运行时，其功率Bn大于或等于比较功率Bn’时，将Bn代入存储模块304中拟合好的转速An下的功率-静压关系曲线公式或表格，得到空调器的实际静压值C，进而将实际静压值C与存储模块304存储的最大标称静压D进行比较，以得出比较结果。Specifically, since the power of the blower motor gradually decreases as the static pressure increases when the rotational speed of the blower motor is fixed, the power of the blower motor changes with the static pressure when the static pressure increases to a certain extent. The changes in the performance will be destroyed, and the power collection may be inaccurate and cannot meet the actual requirements. Therefore, when the blower motor runs at the rotational speed A1, when the power B1 of the blower motor is less than the comparison power B1' stored in the storage module 304, the rotational speed of the blower motor is adjusted to A2, and at this time, if the power of the blower motor is B2 is smaller than the comparison power B2' stored in the storage module 304, and the rotation speed of the blower motor is adjusted to A3, and the power B3 of the blower motor and the comparison power B3' corresponding to the rotation speed A3 stored in the storage module 304 are continuously performed. Compare and repeat the above steps until the power supply Bn is greater than or equal to the comparison power Bn' when the blower motor is running at the rotation speed An, and substitute the Bn into the power-static pressure relationship curve of the fitted rotation speed An in the storage module 304. The formula or table obtains the actual static pressure value C of the air conditioner, and then compares the actual static pressure value C with the maximum nominal static pressure D stored by the storage module 304 to obtain a comparison result.

其中，空调器是风管式空调器，风管式空调器在接收开机运行信号时，送风电机首先在M分钟内以存储模块604中预设的第一预设转速R1运行，M的取值范围是1分钟～10分钟，优选的，M的取值为3～5分钟。Wherein, the air conditioner is a duct type air conditioner, and when the duct type air conditioner receives the start running signal, the blower motor first runs in the M minute within the first preset speed R1 preset in the storage module 604, and the M is taken. The value ranges from 1 minute to 10 minutes. Preferably, the value of M is 3 to 5 minutes.
进一步的，电流采集模块602自动检测送风电机的消耗工作电流L1；中央处理器606调用该消耗工作电流L1并与存储模块604中预设的比较电流L1’比较，若L1≥L1’，则将此工作电流代入存储模块604中拟合好的第一预设转速下的电流-静压关系曲线公式或表格，得到当前实际 静压值A；若L1<L1’，中央处理器606给送风电机发出指令以存储模块604中预设的第二预设转速R2运行。Further, the current collecting module 602 automatically detects the consumed operating current L1 of the blower motor; the central processing unit 606 calls the consumed operating current L1 and compares with the preset comparison current L1' in the storage module 604. If L1≥L1', then Substituting the working current into the current-static pressure relationship curve formula or table at the first preset speed in the storage module 604 to obtain the current actual The static pressure value A; if L1 < L1', the central processing unit 606 issues an instruction to the air supply motor to operate at a second preset rotational speed R2 preset in the storage module 604.

进一步的，电流采集模块602自动检测送风电机的消耗工作电流L2，由于该实施例中以预设两个转速值为例进行说明，故在此假设当送风电机以第二预设转速R2运行时，送风电机的消耗工作电流L2大于或等于存储模块604中预设的比较电流L2’。中央处理器606调用该消耗工作电流L2并将L2代入存储模块604中拟合好的第二预设转速下的工作电流-静压关系曲线公式或表格，得到当前实际静压值A。Further, the current collecting module 602 automatically detects the operating current L2 of the air-sending motor. Since the preset two speed values are used as an example in the embodiment, it is assumed here that the air-sending motor has a second preset speed R2. In operation, the consumption operating current L2 of the blower motor is greater than or equal to the preset comparison current L2' in the storage module 604. The central processing unit 606 calls the consumption operating current L2 and substitutes L2 into the operating current-static pressure relationship curve formula or table at the second preset rotation speed fitted in the storage module 604 to obtain the current actual static pressure value A.
进一步的，中央处理器606调用存储模块604中最大标称静压D并与实际静压值A比较，若A≤D则发送“OK”代码给显示装置608；若A>D则发送“NG”代码给显示装置608；显示装置608最终将实际静压值A和判定结果显示出来，简单明了得出所安装风管是否合格的结论。Further, the central processing unit 606 calls the maximum nominal static pressure D in the storage module 604 and compares it with the actual static pressure value A. If A≤D, an "OK" code is sent to the display device 608; if A>D, the "NG" is sent. The code is given to the display device 608; the display device 608 finally displays the actual static pressure value A and the determination result, and simply concludes that the installed air duct is qualified.

步骤704具体为中央处理器606给风管式空调器送风电机发送指令，以存储模块604中预设的第一预设转速R1运转。Step 704 is specifically that the central processing unit 606 sends an instruction to the air duct air conditioner air supply motor to operate at a first preset rotation speed R1 preset in the storage module 604.
步骤706具体为电流采集模块602检测风管式空调器送风电机当前的消耗工作电流L1。检测工作电流要在送风电机以R1运行M分钟后进行，目的是确保送风电机已经运行稳定，M的取值范围是1分钟～10分钟，优选的，M的取值为3～5分钟。Step 706 is specifically for the current collecting module 602 to detect the current operating current L1 of the air blower of the air duct type air conditioner. The detection working current should be performed after the air supply motor runs for R minutes for R1. The purpose is to ensure that the air supply motor has been running stably. The value of M is from 1 minute to 10 minutes. Preferably, the value of M is 3 to 5 minutes. .
步骤708和步骤710具体为将检测到的风管式空调器送风电机工作电流L1与存储模块604中预设的比较电流L1’对比，若L1≥L1’则将此工作电流代入存储模块604中拟合好的第一预设转速下的电流-静压关系曲线公式或表格，得到当前实际静压值；其中，比较电流L1’是事先存储在存储模块604中的数值，当送风电机运行R1时，随着静压的增大，电机工作电流逐渐减小，当静压大到一定程度时，电机工作电流随静压变化而表现出来的变化规律会被破坏，或者工作电流采集不准确而无法满足实际要求，因此设置比较电流L1’这个参数，用来判断是否需要变更预设转速。 Step 708 and step 710 are specifically: comparing the detected airflow fan air supply operating current L1 with the preset comparison current L1' in the storage module 604. If L1≥L1', the working current is substituted into the storage module 604. The current-static pressure relationship curve formula or table at the first preset speed is fitted to obtain the current actual static pressure value; wherein the comparison current L1' is a value previously stored in the storage module 604, when the air supply motor When R1 is operated, the working current of the motor gradually decreases with the increase of static pressure. When the static pressure is large to a certain extent, the change law of the working current of the motor with the change of static pressure will be destroyed, or the working current collection will not be Accurate and can not meet the actual requirements, so set the comparison current L1 'this parameter to determine whether the preset speed needs to be changed.
其中，第一预设转速下的工作电流-静压关系曲线公式或表格，是在送风电机运行存储模块604中预设的第一预设转速R1时，通过若干组静压和工作电流的对应数据拟合得到或直接列表得出。步骤708是由中央处理器606调用工作电流采集模块602的检测结果并进行工作电流比较，同时调用存储模块604中的电流-静压关系曲线公式或表格，通过计算得到当前实际静压。例如，当R1＝1200rpm时，通过实验发现静压与工作电流存在如表2所示的对应关系：The operating current-static pressure relationship curve formula or table at the first preset speed is a set of static pressure and working current when the first preset speed R1 preset in the air supply motor running storage module 604 Corresponding data fitting is obtained or directly listed. Step 708 is to call the detection result of the working current collecting module 602 by the central processing unit 606 and compare the working current, and simultaneously call the current-static pressure relationship curve formula or table in the storage module 604, and obtain the current actual static pressure by calculation. For example, when R1=1200 rpm, it is found through experiments that the static pressure and the working current have the corresponding relationship as shown in Table 2:
转速R1(rpm)Speed R1 (rpm) 12001200 12001200 12001200 12001200 12001200 12001200 12001200 12001200 12001200 12001200 12001200 12001200
静压(Pa)Static pressure (Pa) 00 1010 2020 3030 4040 5050 6060 7070 8080 9090 100100 110110
工作电流(A)Working current (A) 2.82.8 2.712.71 2.572.57 2.442.44 2.312.31 2.182.18 2.072.07 1.931.93 1.781.78 1.641.64 1.31.3 0.820.82
表2Table 2
根据表2中所示的数据，拟合得到图8所示的曲线。假设当存储模块604中存储的比较电流L1’＝1.6A，送风电机以预设转速1200rpm运行时，检测到的电机工作电流L1＝2.35A，比较L1和L1’的大小可知L1≥L1’，故可采用第一预设转速R1时的工作电流-静压对应关系来计算当前静压值。通过表2可知当前静压值在30Pa～40Pa之间，可以选择就近原则，即L1靠近2.31A，认为当前静压是40PA，也可以在30Pa～40Pa之间选择线性插值法，得出当前静压值为36.92Pa。更精确的做法是基于表2中数据，通过数据拟合，得到预设转速R1时工作电流-静压关系曲线，优选最小二乘法进行拟合，例如根据表2中所示的数据拟合得到下述公式：According to the data shown in Table 2, the curve shown in Fig. 8 was obtained. It is assumed that when the comparison current L1'=1.6A stored in the storage module 604 and the blower motor is operated at the preset rotation speed of 1200 rpm, the detected motor operating current L1=2.35A, and the magnitudes of L1 and L1' are compared to know that L1≥L1' Therefore, the current static pressure value can be calculated by using the working current-static pressure correspondence relationship at the first preset rotation speed R1. It can be seen from Table 2 that the current static pressure value is between 30Pa and 40Pa, and the principle of proximity can be selected, that is, L1 is close to 2.31A, and the current static pressure is 40PA. Linear interpolation can also be selected between 30Pa and 40Pa to obtain the current static. The pressure is 36.92 Pa. More precisely, based on the data in Table 2, the data is fitted to obtain the operating current-static pressure relationship curve at the preset speed R1, preferably by least squares method, for example, according to the data fitting shown in Table 2. The following formula:
y＝-77.031x+217.8y=-77.031x+217.8
其中，x为送风电机的工作电流，y为静压值。将检测到的送风电机的工作电流代入上述公式，可直接算出当前的静压值，计算精度更高。Where x is the operating current of the blower motor and y is the static pressure value. By substituting the detected operating current of the blower motor into the above formula, the current static pressure value can be directly calculated, and the calculation accuracy is higher.
本发明的实施例并不限于此，例如可根据风管式空调器的最大静压与0静压之间设置5～100个均分或不均分的静压值，并通过上述实验方式得到5～100组电流-静压对应关系，形成类似于表2的参数表格进而得出相应的拟合公式。The embodiment of the present invention is not limited thereto. For example, a static pressure value of 5 to 100 equalization or unevenness may be set according to the maximum static pressure and the zero static pressure of the air duct type air conditioner, and obtained by the above experimental method. The current-static pressure correspondence of 5 to 100 sets forms a parameter table similar to Table 2 to obtain a corresponding fitting formula.
从表2和图8可以发现，当静压在0～90Pa之间时，数据存在良好的变化规律；当静压在100Pa以上，工作电流随静压的变化规律明显发生改 变；当静压在110Pa以后已经很难准确测出工作电流值，因此需要提高送风电机的转速，以重新寻找工作电流随静压的变化规律，从而判断当前静压值。It can be found from Table 2 and Figure 8 that when the static pressure is between 0 and 90 Pa, the data has a good change rule; when the static pressure is above 100 Pa, the working current changes with the static pressure. When the static pressure is 110Pa, it is difficult to accurately measure the working current value. Therefore, it is necessary to increase the rotational speed of the blower motor to find the change law of the working current with the static pressure, so as to judge the current static pressure value.
图7中所示的步骤712具体为中央处理器606给风管式空调器送风电机发送指令，以存储模块604中预设的第二预设转速R2运转，其中R2数值要大于R1。The step 712 shown in FIG. 7 is specifically that the central processing unit 606 sends an instruction to the air duct air supply motor to operate at a second preset speed R2 preset in the storage module 604, wherein the value of R2 is greater than R1.
步骤714具体为工作电流采集模块602检测风管式空调器送风电机当前的消耗工作电流L2。检测工作电流要在送风电机以R2运行N分钟后进行，目的是确保电机已经运行稳定，N的取值范围是1分钟～10分钟，优选的，N的取值为3～5分钟。Step 714 is specifically for the working current collecting module 602 to detect the current consumption operating current L2 of the air duct of the air duct type air conditioner. The detection working current is to be performed after the air supply motor is operated for R minutes for R minutes. The purpose is to ensure that the motor has been running stably. The value of N ranges from 1 minute to 10 minutes. Preferably, the value of N is 3 to 5 minutes.
步骤716具体为将检测到的风管式空调器送风电机工作电流L2代入存储模块604中拟合好的第二预设转速下的电流-静压关系曲线公式或表格，得到当前实际静压值。例如，当R2＝1450rpm时，通过实验发现静压与工作电流存在如表3所示的对应关系：Step 716 is specifically: substituting the detected air duct air supply operating current L2 into the current-static pressure relationship curve formula or table at the second preset speed in the storage module 604 to obtain the current actual static pressure. value. For example, when R2=1450rpm, it is found through experiments that the static pressure and the working current have the corresponding relationship as shown in Table 3:
转速R2(rpm)Speed R2 (rpm) 14501450 14501450 14501450 14501450 14501450
静压(Pa)Static pressure (Pa) 100100 110110 120120 130130 140140
工作电流(A)Working current (A) 3.133.13 3.003.00 2.862.86 2.712.71 2.582.58
表3table 3
例如，当送风电机以预设转速1450rpm运行时，检测到的电机工作电流为2.9A，通过表3可知当前静压值在110Pa～120Pa之间，可以选择就近原则，即L2靠近2.86A，认为当前静压是120Pa，也可以在110Pa～120Pa之间选择线性插值法，得出当前静压值为117.1Pa。更精确的做法是根据表3中的数据，通过数据拟合，得到预设转速R2时电流-静压关系曲线，优选最小二乘法进行拟合，例如根据表3中的数据拟合得到下述公式：For example, when the air supply motor is operated at a preset speed of 1450 rpm, the detected motor operating current is 2.9 A. It can be seen from Table 3 that the current static pressure value is between 110 Pa and 120 Pa, and the principle of proximity can be selected, that is, L2 is close to 2.86 A. It is considered that the current static pressure is 120 Pa, and the linear interpolation method can also be selected between 110 Pa and 120 Pa, and the current static pressure value is 117.1 Pa. More precisely, according to the data in Table 3, by data fitting, the current-static pressure relationship curve at the preset rotation speed R2 is obtained, and the least squares method is preferably used for fitting, for example, according to the data fitting in Table 3, the following is obtained. formula:
y＝-71.902x+325.4y=-71.902x+325.4
其中，x为送风电机工作电流，y为静压值。然后将检测到的送风电机工作电流代入该公式可直接算出当前静压值，精度更高。Where x is the operating current of the blower motor and y is the static pressure value. Then, the detected working current of the blower motor is substituted into the formula to directly calculate the current static pressure value, and the precision is higher.
本发明的实施例并不限于此，例如可根据风管式空调器的最大静压与0静压之间设置5～100个均分或不均分的静压值，并通过上述实验方式得到5～100组电流-静压对应关系，形成类似于表3的参数表格进而得出 相应的拟合公式。The embodiment of the present invention is not limited thereto. For example, a static pressure value of 5 to 100 equalization or unevenness may be set according to the maximum static pressure and the zero static pressure of the air duct type air conditioner, and obtained by the above experimental method. 5 to 100 sets of current-static pressure correspondence, forming a parameter table similar to Table 3 and then The corresponding fitting formula.
图7所示的步骤718至步骤722是指中央处理器606调用存储模块604中最大标称静压D的数值，同时调用步骤710或步骤716中计算出来的实际静压值A，比较A和D的大小关系，若A≤D则发送“OK”代码给显示装置608；若A>D则发送“NG”代码给显示装置608。“OK”代码表示所安装风管的静压没有超出最大标称静压，安装合格；“NG”表示所安装风管的静压已经超出最大标称静压，安装不合格，需要重新设计风管尺寸或布局。应当指出的是，“OK”或“NG”代码只是用来表示判定上述结果是否超标的一种标志，其他任何表示该结果的代码均在本发明的保护范围之内。 Steps 718 to 722 shown in FIG. 7 refer to the central processor 606 calling the value of the maximum nominal static pressure D in the storage module 604, and simultaneously calling the actual static pressure value A calculated in step 710 or step 716, comparing A and The magnitude relationship of D, if A ≤ D, sends an "OK" code to display device 608; if A > D, an "NG" code is sent to display device 608. The “OK” code indicates that the static pressure of the installed duct does not exceed the maximum nominal static pressure, and the installation is qualified; “NG” indicates that the static pressure of the installed duct has exceeded the maximum nominal static pressure, the installation is unqualified, and the wind needs to be redesigned. Tube size or layout. It should be noted that the "OK" or "NG" code is only a sign indicating whether the above result is exceeded, and any other code indicating the result is within the scope of the present invention.
由于显示装置608将步骤710或步骤716中计算出来的静压值A显示出来，同时将比较结果显示出来，给工程验收或设计人员直观的判断依据和结果。显示装置608通常为风管式空调器的线控器、遥控器或接收面板等。Since the display device 608 displays the static pressure value A calculated in step 710 or step 716, and simultaneously displays the comparison result, the engineering acceptance or the designer intuitively judges the basis and the result. The display device 608 is typically a wire controller, remote control or receiving panel of a ducted air conditioner.
本领域的技术人员需要理解的是，该实施例以2个预设转速为例阐述了检测空调器安装规范性的方案，对于2个以上的预设转速，同样适用于上述实施例的技术方案。即在送风电机以转速R1运行时，送风电机的工作电流L1小于存储模块604中存储的比较电流L1’时，将送风电机的转速调为R2，此时，若送风电机的工作电流L2小于存储模块604中存储的比较电流L2’，则将送风电机的转速调为R3，并继续将送风电机的工作电流L3与存储模块604中存储的对应于转速R3的比较电流L3’进行比较，并重复上述步骤，直到送风电机以转速Rn运行时，其工作电流Ln大于或等于比较电流Ln’时，将Ln代入存储模块604中拟合好的转速Rn下的电流-静压关系曲线公式或表格，得到空调器的实际静压值A，进而将实际静压值A与存储模块604存储的最大标称静压D进行比较，以得出比较结果。It should be understood by those skilled in the art that the embodiment illustrates the scheme for detecting the installation accuracy of the air conditioner by taking two preset rotation speeds as an example.

That is, when the blower motor is operated at the rotational speed R1, when the operating current L1 of the blower motor is smaller than the comparison current L1' stored in the storage module 604, the rotational speed of the blower motor is adjusted to R2, and at this time, if the blower motor operates When the current L2 is smaller than the comparison current L2' stored in the storage module 604, the rotation speed of the air supply motor is adjusted to R3, and the operating current L3 of the air supply motor and the comparison current L3 corresponding to the rotation speed R3 stored in the storage module 604 are continued. 'Comparison, and repeat the above steps until the operating motor Ln is greater than or equal to the comparison current Ln' when the blower motor is running at the rotational speed Rn, and the Ln is substituted into the current at the fitted rotational speed Rn in the storage module 604. The pressure relationship curve formula or table obtains the actual static pressure value A of the air conditioner, and then compares the actual static pressure value A with the maximum nominal static pressure D stored by the storage module 604 to obtain a comparison result.
