[0044]图2是本发明除湿机压缩机保护控制方法较佳实施例的流程示意图。 [0044] FIG. 2 is a schematic flow chart of a control method of a compressor protection dehumidifier preferred embodiment of the present invention.

[0045]为了使本发明的技术方案更加清楚、明了,下面将结合附图作进一步详述。 [0045] In order to make the technical solutions of the present invention more clearly understood, will be described in detail further below in conjunction with the accompanying drawings.

具体实施方式 Detailed ways

[0046]应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。 [0046] It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention. [0047]本发明实施例的解决方案主要是:通过监测除湿机的压缩机的电流,根据监测到的压缩机的电流,对除湿机的风机的转速进行控制,防止由于系统压力过高而烧毁压缩机, 提高压缩机的使用安全性和系统稳定性。 [0047] The solution according to an embodiment of the present invention are: the compressor according to the monitored current, the rotation speed of the fan is controlled dehumidifier compressor current monitored by the dehumidifier, and prevent the system pressure is too high and burning compressors, improve the safety and stability of the compressor.

[0048]如图1所示,本发明较佳实施例提出一种除湿机,包括相互连接构成主回路的压缩机1、蒸发器3、节流装置4、冷凝器5,冷凝器5上设有风机6,所述压缩机1上设有储液罐2,本实施例除湿机还包括用于监测所述压缩机1电流的互感器,以及用于根据所述互感器监测到的压缩机1的电流,对风机6的转速进行控制的控制器,当然该控制器可以使用除湿机中用来控制主回路正常工作的控制器。 [0048] As shown in FIG 1, the preferred embodiment of the present invention provides a dehumidifier, including a compressor connected to one another constituting the main circuit 1, an evaporator 3, 4 is provided, condenser 5, expansion device condenser 5 there fan 6, the compressor 1 is provided on the tank 2, the dehumidifier according to the present embodiment includes a further embodiment of a current transformer monitoring said compressor, and a compressor for monitoring according to the transformer 1 current, the fan rotational speed controller 6 is, of course, the controller may use the controller for controlling the dehumidifier main circuit normal operation.

[0049]压缩机1作为除湿机的重要组成元件,其使用安全性尤为重要。 [0049] As an important element of the compressor 1 dehumidifier, which is particularly important safety in use. 而环境温度过高是导致系统压力过高的主要原因之一,当环境温度升高时,冷凝器5的压力将会升高,压缩机1 的压力上升,此时压缩机1的排气温度以及电流也会不断的升高,当电流达到一定值时,压缩机1的接线端子处容易产生打火现象,导致火灾的产生。 Ambient temperature is too high and is one of the main causes of the high pressure system, when the ambient temperature rises, the pressure of the condenser 5 will rise, the pressure of the compressor 1 is increased, the exhaust temperature of the compressor case 1 and a current will continue to rise, when the current reaches a certain value, at the terminals of the compressor 1 is prone to ignition phenomena, resulting in a fire.

[0050] 本实施例方案通过对电流的监控来调节风机6转速,进而对压缩机1的运行状态进行调整,可以达到降低系统压力,最终降低压缩机1电流的目的。 [0050] Example embodiment of the present embodiment is adjusted by monitoring the current fan speed 6, further operating state of the compressor 1 is adjusted, it is possible to reduce the system pressure, the ultimate purpose of reducing a current of the compressor.

[0051] 本实施例风机6的转速的控制第一种实施方式是通过预先设置多个档位来实现, 比如低风档和高风档(普通档和强力档)两个档位,或者高、中、低风三个档位,或者更多档位。 [0051] The speed control of the present embodiment, a first embodiment turbine in Example 6 is achieved by presetting a plurality of gears such as low and high wind speed the wind speed (normal speed and power range) two gears, or high , in low wind three positions, or more gear positions. 本实施方式将分别以两个档位和三个档位进行举例说明。 In the present embodiment, respectively three and two gear shift be exemplified.

[0052] 为了监控压缩机1运行中的电流,本实施例在控制电路上增设了互感器,通过互感器实时或间隔时间监控压缩机1运行中的电流,并对风机6的电流设定了两个电流警戒值, 第一预设阈值A和第二预设阈值B,其中B>A,然后由控制器根据互感器监测到的压缩机1的电流对风机6的转速进行控制。 [0052] In order to monitor the current operation of the compressor 1 in the present embodiment, the addition of a control circuit in the transformer, the transformer by monitoring the current in real time or time interval in the operation of the compressor 1, and set the current fan 6 two current guard value, the first threshold value a and the preset second preset threshold value B, where B> a, and monitored by the controller of the compressor in accordance with a current transformer 1 of 6 of the fan speed is controlled.

[0053] 具体控制过程如下: [0053] The specific control process is as follows:

[0054] 当除湿机接收到开启命令时,先判断室内湿度是否低于设定湿度(室内湿度可以通过相应的传感器来检测),如果室内湿度低于设定湿度,则不开启除湿机,反复监控直到室内湿度高于设定湿度时,开启除湿机的压缩机1以及风机6,并默认除湿机开启后,风机6 以低风档(普通档)运行。 [0054] When the dehumidifier open command is received, first determine whether the indoor humidity is lower than the set humidity (indoor humidity can be detected by the corresponding sensor), if the indoor humidity is lower than the set humidity, the dehumidifier is not turned on, repeated monitored until the indoor humidity is higher than the set humidity, turning on a compressor and a dehumidifier fan 6, and is turned on by default after the dehumidifier, fan 6 operating at low wind speed (normal speed).

[0055] 如前所述,环境温度过高是导致系统压力过高的主要原因之一,因此,本实施例方案还需要对环境温度T进行检测,该环境温度T为室内环境温度,可以通过设置在蒸发器3进风口位置上的温度传感器测量获得。 [0055] As described above, the ambient temperature is too high, one of the main causes the system pressure is too high, and therefore, embodiments of the present embodiment needs to detect the environmental temperature T, T is the temperature of the ambient room temperature, by a temperature sensor disposed in the air inlet of the evaporator 3 on the position obtained by the measurement.

[0056]这样根据检测的环境温度T判断系统是否是由于环境温度高导致压缩机1的电流高,还是压缩机1异常导致的压缩机1电流高。 [0056] Thus, according to the ambient temperature T detected by the system determines whether the ambient temperature is high resulting in a high current of the compressor 1, the compressor 1 or compressor 1 due to abnormal high currents.

[0057]由此,本实施例方案还设置有一环境温度阈值M(M的取值范围可以为27-35°C),并针对环境温度的不同取值,对风机6的转速及压缩机1的运行状态进行控制。 [0057] Thus, embodiments of the present embodiment is also provided with a temperature threshold value M (M may be in the range of 27-35 ° C), and for different values ​​of the ambient temperature, the fan speed and the compressor 16 is running state control.

[0058]具体地,首先监测环境温度T是否达到预设值M,当监测到环境温度T达到预设值M, 即T>=M时,压缩机1电流的互感器监测除湿机的压缩机1的电流。 [0058] Specifically, first monitor the ambient temperature reaches a preset value T M, when the monitored temperature reaches a preset value T M, i.e., the compressor T> time = M, 1 current transformer monitoring compressor dehumidifier current 1.

[0059] 压缩机1电流的互感器可以实时监测除湿机的压缩机1的电流,也可以间隔预定时间(比如0.2s)监测压缩机1的电流。 [0059] The current transformer of the compressor 1 can be monitored in real time dehumidifier current compressor 1 may be a predetermined time interval (for instance 0.2s) monitoring current of the compressor 1.

[0060] 一、以风机6具有低风档和高风档两个转速档位为例,当监测到压缩机1的电流未达到苐一预设阈值A时,将风机6的转速保持默认的低风档。 [0060] First, a low gear and a high wind speed the wind turbine 6 has a two speed gear as an example, when the monitored current of the compressor 1 does not reach a preset threshold value Ti A, the fan speed to keep the default 6 low windshield. 当监测到压缩机丨的电流〗高于第一预设阈值^但没有超过压缩机i第二预设阈值B时,控制器控制风机6的转速由默认的低风档切换成高风档,以增大冷凝器5的散热风量,降低冷凝器5的压力,从而降低压缩机1 的压缩比以及电流,其中本实施方式中B>A。 When the compressor Shu the monitored current is higher than a first predetermined threshold〗 ^ i, but the compressor does not exceed a second predetermined threshold value B, the controller controls the rotational speed of the fan 6 is switched from the default low speed to a high wind speed the wind, to increase the amount of cooling air of the condenser 5, reducing the pressure in the condenser 5, thereby reducing the compression ratio of the compressor 1 and the current, wherein the present embodiment, B> a.

[0061]之后,互感器继续监控压缩机i电流。 After [0061], i compressor continues to monitor the current transformer.

[0062] _除湿机在风机6采用高风档运行后,系统压力会下降。 [0062] _ dehumidifier fan 6 after high operating windshield, the system pressure will drop. 在除湿机以调节风机转速后持续运行预定时间后,控制器判断压缩机1的电流是否小于第一预设阈值A且持续预设时间;若是,则将风机6的转速调整为低风档;若否,则除湿机继续运行,直到判断压缩机丨的电流低于第一预设阈值且持续预定时间,并将所述风机6的转速调整为低风档。 After continuous operation for a predetermined time after the dehumidifier to adjust the fan speed, the controller determines the current of the compressor 1 is less than a first predetermined threshold value A and the predetermined time duration; if, then the fan speed 6 is adjusted to a low wind speed; If not, the dehumidifier continue to run until the compressor Shu determination current is below a first predetermined threshold for a predetermined time, and the fan speed 6 is adjusted to a low wind speed.

[0063]此外,当监测到压缩机1的电流达到第二预设阈值B时,停止压缩机1运行,并将风机6的转速调整为高风档;在压缩机1关闭设定时间后,重新启动压缩机丨,同时监测压缩机1 的电流,重复上述根据压缩机1的电流控制风机6的转速的过程。 [0063] Further, when the monitored current of the compressor 1 reaches the second preset threshold value B, to stop operation of the compressor 1, and the fan speed 6 is adjusted to a high wind speed; 1 compressor off after a set time, Shu compressor is restarted, while monitoring the current of the compressor 1, the above process is repeated according to the current fan speed control of the compressor 1 6.

[0064]例如,当监测到压缩机1的电流I高于第一预设阈值A,但没有超过压缩机i第二预设阈值B时,控制器控制风机6的转速由默认的低风档切换成高风档。 [0064] For example, when the monitored current I of the compressor 1 is higher than a first preset threshold value A, but the compressor does not exceed a second predetermined threshold value B i, the controller 6 controls the fan speed by default low windshield switched to the high speed wind. 之后,当控制器监控到压缩机1的电流低于第一预设阈值A并持续5分钟后,控制器控制风机6切换成低风档。 Thereafter, when the controller monitors the current to the compressor 1 is lower than a first predetermined threshold value A for 5 minutes, the controller controls the fan 6 is switched to the low air speed. 当监控到压缩机1的电流达到第二预设阈值B,且持续5秒时,强行关闭压缩机1,控制器控制风机6切换成高风档运行。 When the current reaches the compressor 1 is monitored second preset threshold value B, and the time for 5 seconds, the compressor 1 is forcibly closed, the controller controls the fan 6 is switched to the high wind speed operation. 压缩机1关闭30分钟后,启动压缩机1,同时监控压缩机1的电流,重复上述根据压缩机1的电流控制风机6的转速的过程。 After 30 minutes turn off the compressor 1, the compressor 1 starts, while monitoring the current of the compressor 1, the above process is repeated according to the current fan speed control of the compressor 1 6.

[0065]通过上述控制操作,可有效避免由于压力过高导致压缩机1堵转烧压缩机丨以及其它导致压缩机1电流高起火事故的发生。 [0065] By the above-described control operations, can effectively avoid the high pressure of the compressor 1 leads to a compressor stall burn Shu cause the compressor 1, and other high current fire accidents.

[0066]二、下面以风机6具有高、中、低三档转速为例,对本实施方式中根据监测到的压缩机1的电流,对除湿机的风机6的转速进行控制的原理进行详细阐述: [0066] Second, the fan 6 below to have a high, medium and low speed, for example, according to the present embodiment, the current monitoring to the compressor 1, the rotational speed of the fan 6 dehumidifier control principle is explained in greater detail :

[0067]根据监测的压缩机1的电流值区域,确定风机6对应的转速并将其切换到对应的转速来实现降低冷凝器5的系统压力,达到降低压缩机1负荷的目的,同时在切换风机6的转速后,持续运行一段时间然后再判断电流的范围是否仍在安全电流值以下,若不是,则按照之前的风速进行运转,直到达到预设值时才将其切换到低风档,这样能防止风机6经常切换风速而带来的电流的波动,增加系统的稳定性。 [0067] The current value of the monitored region of the compressor 1, the fan 6 is determined corresponding to the rotational speed and the switching speed corresponding to achieve a reduction in pressure in the condenser system 5, to reduce a load of the compressor, while the switching after 6 fan speed, continuous operation for some time and then determines whether the current range is still safe current value, if not, the operation is performed in accordance with the previous wind speed, until it reaches a preset value when switching to the low windshield, this prevents frequent fluctuation of the fan 6 is switched to bring the current wind speed, increase the stability of the system.

[0076] 此外,当监测到压缩机1的电流达到第二预设阈值B(B>A+2Q)时,停止压缩机1运行,并将所述风机6的转速调整为高风档;在压缩机1关闭设定时间后,重新启动压缩机1,同时监测压缩机1的电流,重复上述具有三档过程中根据压缩机1的电流控制风机6的转速的过程。 [0076] Further, when the monitored current of the compressor 1 reaches the second preset threshold value B (B> A + 2Q), to stop operation of the compressor 1 and the fan speed 6 is adjusted to a high wind speed; in after a set time the compressor 1 is turned off to restart the compressor 1, while monitoring the current compressor 1 to repeat the above processes in which the third gear with a current speed of the compressor 1 is controlled fan 6.

[0077]另外,当监测到环境温度未达到预设值时,若监测到压缩机1的电流A<I<B,将所述风机6的转速调整为中风档或高风档,持续预定时间后,若监测到压缩机1的电流不低于A, 则停止压缩机1运行;若监测到压缩机1的电流KA,将所述风机6的转速保持默认的低风档。 [0077] Further, when the monitored temperature does not reach the predetermined value, when the monitored current compressor A <I <B 1 of the fan speed is adjusted to 6 or higher stroke speed windshield, for a predetermined time after, if the monitored current is less than the compressor 1 is not a, then stop the operation of the compressor 1; if the monitored current KA the compressor 1, the rotational speed of the fan 6 is kept low windshield default. [0078] 具体实例如下: [0078] Specific examples are as follows:

[0079]当环境温度T>=M度时,发现压缩机1电流I高于警戒值A但没有超过压缩机1极限值B时,其中A和B的取值可以根据实际情况进行定义,如:A为[6,15],B为[10,20],具体可为A = 6,B = 10;SA=11,B = 17;SA=15,B = 20: [0079] When the ambient temperature T> = M degrees, I found that the compressor 1 is higher than the current guard value A, but the compressor does not exceed a limit value B, wherein A and B values ​​can be defined according to the actual situation, such as : A is [6,15], B is [10,20], may be particularly A = 6, B = 10; SA = 11, B = 17; SA = 15, B = 20:

[0080] 步骤1、电流在A<I<A+Q【Q的取值范围为[1,3]】时,本实施例中Q=2,启动控制器控制风机6切换成中风档,实时监控压缩机1电流,连续预定时间一C【C的取值范围为[10,18]】 分钟内电流小于A+Q,且每隔一分钟将监控电流与上一分钟电流比较,C分钟内,后者都比前者小,则C分钟后判断电流是否到达A以下,如果到达则运行上述C分钟后再次判断是否连续预定时间一D分钟【D的取值范围为[2,5]】分钟内低于A电流。 When [0080] Step 1, a current A <I <A + Q Q ranges [[1,3]], in the present embodiment, Q = 2, the controller starts the fan 6 is switched to the stroke control gear, real-time monitoring current compressor 1, a continuous predetermined time range {C C is [10, 18] min] within the current of less than a + Q, every one minute and the monitoring current is compared with a minute current, the C min , which are smaller than the former, the C min is determined whether the current reaches a or less, if the arrival run above C min is determined again whether a continuous predetermined time D min {D is in the range [2,5] min] A current is less than the inner. 低于则切换成低风档运行,高于则重复运行预定时间C分钟,直到低于A电流,切换成低风档运行;若C分钟内后者都比前者大或者C分钟内有电流超过A+Q,则C分钟后风机6切换成高风档持续运行,然后每隔一分钟将监控电流与上一分钟电流比较,如果C分钟内后者都比前者小,则C分钟后判断电流是否到达A以下,如果到达则运行C分钟后,再次判断是否连续D分钟内低于A电流。 Below is switched to a low speed operation of wind, a predetermined time is higher than the C min run repeatedly, until the current is less than A, the switching operation to the low wind speed; C within minutes if the latter are larger than the former or current than the C min a + Q, then C 6 minutes after the fan is switched to the high windshield continuous operation, and then every minute to monitor a minute current is compared with the current, if the latter are smaller than the former C min, C min is determined the current A reaches the following, if, after reaching C min run, again determines whether the current is less than A min D continuously. 高于A且小于B则重复运行C分钟,直到连续D分钟内低于A电流,切换成低风档运行,若高于B,则进入步骤4。 A greater than B and less than the C min run repeatedly until the continuous current is less than D A min, operation is switched to the low air speed, if higher than B, the process proceeds to step 4.

[0081] 步骤2、如果电流在A+2Q>I>A+Q。 [0081] Step 2, if the current A + 2Q> I> A + Q. 其中Q = 2,启动控制器控制风机6切换成高风档, 实时监控压缩机1电流,连续C分钟内电流没有超过A+2Q,且每隔一分钟将监控电流与上一分钟电流比较,C分钟内后者都比前者小,则C分钟后判断电流是否到达A+Q以下,如果到达则运行C分钟后再次判断是否低于A+Q电流。 Where Q = 2, the controller controls the fan start switch 6 to a high wind speed, real-time monitoring of a compressor current, the current does not exceed consecutive minutes C A + 2Q, and monitored every minute with a minute current comparison current, the latter are smaller than the former C min, C min is determined whether the current reaches the A + Q, if the operation after reaching C min is determined again whether the current is less than A + Q. 如果电流在A<I<A+Q则执行步骤1,如果电流在连续D分钟内I<A,低于则切换成低风档运行;如连续D分钟内B>I>A则重复运行C分钟,直到连续D分钟内低于A电流;若C分钟内后者都比前者大,持续高风档运转。 If the current A <I <A + Q in step 1 is performed, if the current consecutive minutes in D I <A, below is switched to a low speed operation of wind; D within such consecutive minutes B> I> A repeat run C minutes, until the A continuous current is less than D min; C within minutes if the latter are larger than the former, sustained high speed operation of the wind. 继续监控电流,如果持续D分钟BF>I>B-2F【本实施方式中F=l】,停止压缩机1运行。 It continues to monitor current, if the duration D min BF> I> B-2F [the present embodiment] F = l, stop operation of the compressor 1. 持续高风运行,压缩机1关闭E分钟【E的取值范围为[30,45]】后启动压缩机1同时监控压缩机1电流,重复上述的步骤1-3的控制。 Sustained high wind operation, the compressor 1 minute close E {E is in the range [30, 45]], the compressor 1 while monitoring the electric current of the compressor 1, the control repeats the above steps 1-3.

[0082]步骤3、当监控压缩机1电流超过B时,停止压缩机1运行。 [0082] Step 3, when the monitored current exceeds the compressor 1 B, operation of the compressor 1 is stopped. 持续高风档运行,压缩机1 关闭E分钟后,启动压缩机1同时监控压缩机1电流,重复上述步骤1-3控制过程。 After sustained high wind range operation, the compressor 1 minute E off, starting the compressor 1 while monitoring the electric current of the compressor 1, the control process repeats steps 1-3 above.

[0083]当环境温度T<M度时,监测到压缩机1电流I高于第一预设阈值A但没有超过压缩机1第二阈值B时,切换风机6持续高风运行,监控电流在A〈I时,持续预定时间(如1〇分钟)后, 连续预设时间(如2分钟)内电流不低于A电流。 [0083] When the ambient temperature T <M degrees, monitor the current I to the compressor 1 is higher than the threshold value A, but the compressor does not exceed the second threshold value B 1, the switching operation of the fan 6 a first predetermined sustained high wind, current monitoring after A <I, the predetermined time (e.g., 1〇 minutes), successive predetermined time (e.g., 2 minutes) is not less than the current A current. 则停止压缩机1运行,持续高风档运行并且发出警报,发出错误代码,若检测到I<A时,切换到低风运行,这样能检测到压缩机1刚启动时电流波动的情况。 Operation of the compressor 1 is stopped, and the operation of the windshield sustained high alarm, error code sent, if the detected I <A, switch to a low wind operation, so that the case can be detected when the compressor 1 has just started the current ripple.

[0084] 本实施方式中,高风档运行可以指风速为800一10〇〇转;高风档与中风档,以及中风档与低风档相差150-250转。 [0084] In the present embodiment, may refer to operation of the windshield high wind speed of 800 revolutions a 10〇〇; high stroke speed and wind speed, and wind speed and a low speed stroke, a difference of 150-250 rpm.

[0085]第二种实施方式:风机6可在预设阈值范围内根据检测的电流范围值调节转速。 [0085] The second embodiment: the rotational speed of the fan 6 can be adjusted according to the detected current range within a preset threshold range. 即通过监测到的压缩机的电流与预设阈值进行比较确定风机转速的调节量;根据风机转速的调节量对风机的转速进行调节直到压缩机的电流值达到预设值以下为止。 Namely amount adjusting fan speed is determined by comparing the monitored current with a preset threshold value of the compressor; of the fan speed is adjusted until the current value of the compressor reaches a preset value or less according to the amount of adjustment of the fan speed.

[0086]具体实现如下:将监测到的所述压缩机的电流与预设阈值进行比较;当监测到的所述压缩机的电流在第一预设阈值A与第二预设阈值B之间时,根据监测到的压缩机的电流,查找预设的公式表,获取风机对应的电压值的调节量AU,进而获取风机对应的电压值U 二UA+AU; UA为压缩机的电流为第一预设阈值A时对应的风机的电压值;调整风机的电压至所述获取的对应的电压值,控制所述风机的转速直到压缩机的电流值达到预设值以下为止。 [0086] embodied as follows: a current with a preset threshold value monitored by comparing the compressor; when the monitored current between said compressor in a first predetermined threshold value A and the second predetermined threshold value B when, in accordance with the monitored current of the compressor, a preset lookup table formulas, AU obtain the adjustment amount corresponding to the voltage value of the fan, the fan and thus acquires a voltage value corresponding to U = UA + AU; UA current for the first compressor a preset voltage corresponding to the threshold value a fan; adjusting a voltage corresponding to the fan voltage value to the acquired fan rotation speed of the control value of the compressor until the current reaches a preset value or less.

[0087] 例如,将压缩机1电流在第一预设阈值a与压缩机1第二预设阈值B之间,每增加1安培电流确定对应风机6的电压值,g卩,基于压缩机1电流与风机6的电压值建立一公式表,该公式表中,由电流为第一预设阈值A对应一风机6电压值开始,每增加1安培电流确定有对应风机6的电压值,在监测到压缩机i电流后,查找该公示表,即可得到风机6对应的电压值,调整风机6的电压至对应的电压值,控制风机6的转速,由此,通过调节电机的电压控制风机6 的转速,从而根据电流值精确地调节风机6转速。 [0087] For example, the current value of the compressor in a first predetermined threshold between the compressor 1 and a second preset threshold value B, for each additional 1 amp current determining voltage values ​​corresponding to the fan 6, g Jie, the compressor 1 based on current and voltage values ​​of the fan 6 to establish a formula for the table, the table formulas, a corresponds to a first predetermined threshold voltage value of a blower 6 is started by the current, every increase of 1 ampere corresponding to the fan is determined that there is a voltage value 6, monitoring current i to the compressor, the publicity lookup table, to obtain a voltage value corresponding to the fan 6, the adjustment voltage value corresponding to the fan 6, the control fan speed 6, whereby, by adjusting the control voltage of the motor fan 6 speed, to precisely adjust the fan speed based on the current value of 6.

[0090]步骤11、电流在A〈I<A+Q1时,Q1的取值范围为[1,3],本实施方式中Ql = l,控制器调节风机6电压,将转速调整为原来的{1+ (IA) /Q1}倍【控制器将电机两端的电压相应调节为{1+(IA)/Q1}U,其中U为电流为A时对应的风机6的电压值,从而达到调节风机6转速的目的,这时风机6转速为A电流时转速的{1+(IA)/Q1}倍】。 [0090] Step 11, the current A <I <A + when Q1, Q1 is in the range [1,3], the present embodiment Ql = l, 6 voltage controller regulates fan speed is adjusted to the original {1+ (IA) / Q1} {times the voltage across the motor controller was adjusted to the respective {1+ (IA) / Q1} U, wherein U is the time corresponding to the current voltage value is a fan 6, so as to regulate 6 purpose fan speed, then fan speed is 6 a current speed {1+ (IA) / Q1}} times. 实时监控压缩机1电流,连续C分钟内电流没有超过A+Q1,且每隔一分钟将监控电流与上一分钟电流比较,c分钟内后者都比前者小,则C分钟后判断电流是否到达A以下,如果到达则运行C分钟后再次判断是否连续D分钟内低于A。 Current real-time monitoring of the compressor 1, the minute current does not exceed a continuous C A + Q1, and every minute the current monitoring current comparison with the previous minute, within minutes c which are smaller than the former, it is determined whether the current C min A reaches the following, if, after reaching the run is less than C min is determined again whether the D consecutive minutes A. 低于则风机6电压切换到(I/A)U实现低速运行,高于则重复运行C分钟,直到低于A电流,将风机6电压切换到(I/A) U进行低速运行。 Below the fan 6 is switched to the voltage (I / A) U low speed operation, is higher than the C min run repeatedly, until the current is less than A, the fan 6 is switched to the voltage (I / A) U for low-speed operation. 如果C分钟内后者都比前者小的,则C分钟后判断电流是否到达A以下,如果到达则运行C分钟后再次判断是否连续D分钟内低于A。 If the latter are smaller than the former C min, the C min is determined whether the current reaches A or less, it is determined again if, after reaching C min run continuously if the D is less than A. minutes 高于A小于B则重复运行C分钟,直到连续D分钟内低于A,将风机6电压切换到(I/A)U实现低速运行,若高于B,则进入步骤33。 A less than B is greater than C min run repeatedly, until the A less than D minutes continuously, the fan 6 will be switched to voltage (I / A) U low speed operation, if higher than B, the process proceeds to step 33.

[0091]步骤22、如果电流在A+2Q1>I>A+Q1。 [0091] Step 22, if the current A + 2Q1> I> A + Q1. 启动控制器控制风机6切换成{1+aA)/Q1Hf 转速运行,实时监控压缩机1电流,连续C分钟内电流没有超过A+2Q1,且每隔一分钟将监控电流与上一分钟电流比较,C分钟内后者都比前者小,则C分钟后判断电流是否到达A+2Q1以下,如果到达则运行C分钟后再次判断是否低于A+2Q1电流。 Start the controller controls the fan 6 is switched to {1 + aA) / Q1Hf speed operation, the current real-time monitoring of the compressor 1, the minute current does not exceed a continuous C A + 2Q1, and every minute the current monitoring current comparison with the previous minute , the latter are smaller than the former C min, C min is determined whether the current reaches A + 2Q1 or less, if the operation after reaching C min is determined again whether the current is less than A + 2Q1. 如果电流在A<I<A+Q1则执行步骤11,如果高于A+Q1且小于A+2Q1则重复运行C分钟进入步骤22进行循环,直到连续D分钟内低于A电流,切换成低风档【即(I/A)U】运行,若高于B,则进入步骤33。 If the current is performed in the A <I <A + Q1 step 11, if A + Q1 and less than A + 2Q1 C min is repeated operation proceeds to step 22 to loop continuously until D is less than A current within minutes, switched to a low windshield [i.e. (I / A) U] operation, if higher than B, then proceeds to step 33.

[0092] 以此类推A+3Q1>I>A+2Q1..........直到监控电流持续D分钟超过BF>I>B_2F,停止压缩机1运行。 [0092] and so on A + 3Q1> I> A + 2Q1 .......... duration D min until the monitor current exceeds BF> I> B_2F, operation of the compressor 1 is stopped. 将风机电压切换到(I/B)U1持续高速运行,其中U1为电流为B时风机的电压,压缩机1关闭E分钟后启动压缩机1同时监控压缩机1电流,重复上述的控制。 The fan voltage is switched to (I / B) U1 continuous high-speed operation, wherein the rear fan voltage, the compressor 1 is off the current E U1 minutes to B, the compressor 1 while monitoring the electric current of the compressor 1, the above-described control is repeated.

[0093] 步骤33、当监控压缩机1电流超过B,停止压缩机1运行,本实施方式中B>A+2Q1。 [0093] Step 33, when the monitored current exceeds the compressor 1 B, stop operation of the compressor 1, the present embodiment B> A + 2Q1. 将风机6的电压切换为{I/B}*U1持续高速运行,压缩机1关闭E分钟后,启动压缩机1同时监控压缩机1电流,重复上述步骤11-33的控制过程。 The fan 6 is switched to the voltage {I / B} * U1 sustained high-speed operation, the compressor 1 minute E off, starting the compressor 1 while monitoring the electric current of the compressor 1, repeat the steps 11-33 of the process control.

[0094]当环境温度T<M度时,监控电流A<I〈B时,切换风机6的电压为{I/B}*U1运行,监控电流在A〈I时,持续预定时间(如10分钟)后,连续预定时间(如2分钟)内电流不低于A电流。 [0094] When the ambient temperature T <M degrees, monitor the current A <I <B, the switching voltage of the fan 6 is {I / B} * U1 operation, monitor the current in A <I when, for a predetermined time (e.g., 10 after minutes), continuously for a predetermined time (e.g., 2 minutes) is not less than the current A current. 则停止压缩机1运行,切换风机6的电压为{I/B}*U1高速运行并且发出警报,发出错误代码。 Operation of the compressor 1 is stopped, the fan 6 is switched voltage {I / B} * U1-speed operation and an alarm, an error code is issued. [0095] 本实施例通过上述方案,通过监测除湿机的压缩机1的电流,根据监测到的压缩机1的电流,对除湿机的风机6的转速进行控制,进而实现对压缩机1的精确控制,防止由于系统压力过高而导致起火烧毁压缩机1,提高压缩机1的使用安全性和系统稳定性,且该除湿机装配简单,方便使用。 [0095] The embodiment of the present embodiment, according to the current monitoring compressor 1, the rotational speed of the fan 6 is controlled dehumidifier dehumidifier compressor current monitored by the above-described embodiment 1, and thus accurate compressor 1 control, to prevent excess pressure due to system fire burn the compressor 1, the compressor 1 is used to improve the safety and stability, and the dehumidifier simple assembly, easy to use.

[0096]如图2所示,本发明较佳实施例提出一种除湿机压缩机保护控制方法,基于上述实施例所述的除湿机而实施,该控制方法包括: [0096] As shown in FIG. 2, the preferred embodiment of the present invention provides a method dehumidifier compressor protection control, based on the above embodiments and embodiments of the dehumidifier, the control method comprising:

[0097] 步骤S101,当监测到环境温度达到预设值时,监测除湿机的压缩机的电流; [0097] step S101, and when the monitored temperature reaches a preset value, monitoring a current compressor dehumidifier;

[0098] 步骤S102,根据监测到的所述压缩机的电流,对除湿机的风机的转速进行控制。 [0098] step S102, the compressor according to the current monitored, the rotation speed of the fan is controlled dehumidifier. [0099]如前所述,压缩机作为除湿机的重要组成元件,其使用安全性尤为重要。 [0099] As described above, as an important element of the compressor dehumidifier, which is particularly important safety in use. 而环境温度过高是导致系统压力过高的主要原因之一,当环境温度升高时,冷凝器的压力将会升高, 压缩机的压力上升,此时压缩机的排气温度以及电流也会不断的升高,当电流达到一定值时,压缩机的接线端子处容易产生打火现象,导致火灾的产生。 Ambient temperature is too high and is one of the main causes of the high pressure system, when the ambient temperature rises, the pressure in the condenser will rise, the pressure rise in the compressor, the compressor and the exhaust gas temperature at this time is also a current We will continue to increase, when the current reaches a certain value, at the terminals of the compressor prone to ignition phenomena, resulting in a fire.

[0100] 本实施例方案通过对电流的监控来调节风机转速,进而对压缩机的运行状态进行调整,可以达到降低系统压力,最终降低压缩机电流的目的。 [0100] Example embodiment of the present embodiment is adjusted by monitoring the current fan speed, and thus the operating state of the compressor is adjusted, it is possible to reduce the system pressure, the ultimate purpose of reducing the compressor current.

[0101] 本实施例中步骤S102的第一种实施方式是通过预先设置多个档位来实现,比如低风档和高风档(普通档和强力档)两个档位,或者高、中、低风三个档位,或者更多档位。 [0101] In a first embodiment embodiment of step S102 is achieved by presetting the present embodiment a plurality of gears such as low and high wind speed the wind speed (normal speed and power range) two gears, or high, low wind three positions, or more gear positions. 本实施方式将分别以两个档位和三个档位进行举例说明。 In the present embodiment, respectively three and two gear shift be exemplified.

[0102] 为了监控压缩机运行中的电流,本实施例在控制电路上增设了互感器,通过互感器实时或间隔时间监控压缩机运行中的电流,并对风机的电流设定了两个电流警戒值,第一预设阈值A和第二预设阈值B,其中B>A,然后由控制器根据互感器监测到的压缩机的电流对风机的转速进行控制。 [0102] In order to monitor the current operation of the compressor of the present embodiment on the control circuit of the additional transformers, transformer by monitoring the current in real time or time interval in the operation of the compressor, and the fan is set to the current two current warning value, a first threshold value a and the preset second preset threshold value B, where B> a, then monitored by the controller in accordance with the current transformer of the compressor fan speed control.

[0103] 具体控制过程如下: [0103] DETAILED control process is as follows:

[0104] 当除湿机接收到开启命令时,先判断室内湿度是否低于设定湿度(室内湿度可以通过相应的传感器来检测),如果室内湿度低于设定湿度,则不开启除湿机,反复监控直到室内湿度高于设定湿度时,开启除湿机的压缩机以及风机,并默认除湿机开启后,风机以低风档(普通档)运行。 [0104] When the dehumidifier open command is received, first determine whether the indoor humidity is lower than the set humidity (indoor humidity can be detected by the corresponding sensor), if the indoor humidity is lower than the set humidity, the dehumidifier is not turned on, repeated monitored until the indoor humidity is higher than the set humidity, the dehumidifier open compressors and fans, and the dehumidifier is turned on by default, the fan operating at low wind speed (normal speed).

[0105] 如前所述,环境温度过高是导致系统压力过高的主要原因之一,因此,本实施例方案还需要对环境温度T进行检测,该环境温度T为室内环境温度,可以通过设置在蒸发器进风口位置上的温度传感器测量获得。 [0105] As described above, the ambient temperature is too high, one of the main causes the system pressure is too high, and therefore, embodiments of the present embodiment needs to detect the environmental temperature T, T is the temperature of the ambient room temperature, by a temperature sensor disposed at the evaporator inlet position on the measurements obtained.

[0106] 这样根据检测的环境温度T判断系统是否是由于环境温度高导致压缩机的电流高,还是压缩机异常导致的压缩机电流高。 [0106] Thus, according to the detected current compressor temperature T is determined whether the system is due to the high ambient temperature results in higher compressor current, compressor or due to abnormal high.

[0107] 由此,本实施例方案还设置有一环境温度阈值M(M的取值范围可以为27-35°C),并针对环境温度的不同取值,对风机的转速及压缩机的运行状态进行控制。 [0107] Thus, embodiments of the present embodiment is also provided with a temperature threshold value M (M may be in the range of 27-35 ° C), and for different values ​​of the ambient temperature, the operation of the compressor speed and the fan state control.

[0108] 具体地,首先监测环境温度T是否达到预设值M,当监测到环境温度T达到预设值M, 即T>=M时,压缩机电流的互感器监测除湿机的压缩机的电流。 [0108] Specifically, first monitor the ambient temperature reaches a preset value T M, when the monitored temperature reaches a preset value T M, i.e., the compressor T> time = M, compressor current transformer monitoring dehumidifier current.

[0109] 压缩机电流的互感器可以实时监测除湿机的压缩机的电流,也可以间隔预定时间(比如0.2s)监测压缩机的电流。 [0109] compressor current transformer current real-time monitoring of the compressor dehumidifier may be a predetermined time interval (for instance 0.2s) monitoring current of the compressor.

[0110] —、以风机具有低风档和高风档两个转速档位为例,当监测到压缩机的电流未达到第一预设阈值A时,将风机的转速保持默认的低风档。 [0110] - to have a low fan speed and high wind speed gear as an example two wind speed, the compressor when the monitored current does not reach the first preset threshold value A, the fan speed to keep the default low windshield . 当监测到压缩机的电流I高于第一预设阈值A,但没有超过压缩机第二预设阈值B时,控制器控制风机的转速由默认的低风档切换成高风档,以增大冷凝器的散热风量,降低冷凝器的压力,从而降低压缩机的压缩比以及电流,其中本实施方式中B>A。 When the monitored current I of the compressor is higher than a first preset threshold value A, but the compressor does not exceed a second predetermined threshold value B, the controller controls the fan speed is switched from the default low speed to a high wind the wind speed, in order to increase a large amount of cooling air of the condenser, the condenser pressure is reduced, thereby reducing the compression ratio of the compressor and a current, wherein the present embodiment, B> a. 之后,互感器继续监控压缩机电流。 After that, we continue to monitor compressor current transformer.

[0112]除湿机在风机采用高风档运行后,系统压力会下降。 [0112] In the dehumidifier fan with high wind speed operation, the system pressure will drop. 在除湿机以调节风机转速后持续运行预定时间后,控制器判断压缩机的电流是否小于第一预设阈值A且持续预设时间; 若是,则将风机的转速调整为低风档;若否,则除湿机继续运行,直到判断压缩机的电流低于第一预设阈值且持续预定时间,并将所述风机的转速调整为低风档。 After continuous operation for a predetermined time after the dehumidifier to adjust the fan speed, the controller determines the current of the compressor is smaller than a first predetermined threshold value A and the predetermined time duration; if, then fan speed is adjusted to a low wind speed; if not , the dehumidifier to continue running until the compressor is lower than a first determination current value and the predetermined threshold for a predetermined time, and the low fan speed is adjusted to the windshield.

[0113]此外,当监测到压缩机的电流达到第二预设阈值B时,停止压缩机运行,并将风机的转速调整为高风档;在压缩机关闭设定时间后,重新启动压缩机,同时监测压缩机的电流,重复上述根据压缩机的电流控制风机的转速的过程。 [0113] Further, the compressor when the monitored current reaches a second predetermined threshold value B, to stop operation of the compressor, and the fan speed is adjusted to a high wind speed; compressor off after a set time, the compressor restarts , while the current monitoring of the compressor, the compressor of the above process is repeated to control the current speed of the fan. FIG.

[0114]例如,当监测到压缩机的电流I高于第一预设阈值A,但没有超过压缩机第二预设阈值B时,控制器控制风机的转速由默认的低风档切换成高风档。 [0114] For example, when the monitored current I of the compressor is higher than a first preset threshold value A, but the compressor does not exceed a second predetermined threshold value B, the controller controls the fan speed is switched from the default low to a high windscreen windshield. 之后,当控制器监控到压缩机的电流低于第一预设阈值A并持续5分钟后,控制器控制风机切换成低风档。 Thereafter, when the controller monitors the current to the compressor is lower than a first preset threshold value A, and after 5 minutes, the controller controls the fan is switched to the low air speed. 当监控到压缩机的电流达到第二预设阈值B,且持续5秒时,强行关闭压缩机,控制器控制风机切换成高风档运行。 When the monitored current reaches a second compressor preset threshold B, and the time for 5 seconds, forcibly turning off the compressor, the fan controller controls the switching operation of a high wind speed. 压缩机关闭30分钟后,启动压缩机,同时监控压缩机的电流,重复上述根据压缩机的电流控制风机的转速的过程。 After 30 minutes turn off the compressor, starting the compressor, the compressor while monitoring the current, the process is repeated current fan speed control of the compressor in accordance with.

[0115]通过上述控制操作,可有效避免由于压力过高导致压缩机堵转烧压缩机以及其它导致压缩机电流高起火事故的发生。 [0115] By the above-described control operations, can effectively avoid the high pressure of the compressor results in a compressor stall occurs burning fire and other accidents resulting in high compressor current.

[0116]下面以风机具有高、中、低三档转速为例,对本实施方式中根据监测到的压缩机的电流,对除湿机的风机的转速进行控制的原理进行详细阐述: [0116] In the following the fan having a high, medium and low speed, for example, according to the present embodiment, the compressor is monitored current, fan speed of the dehumidifier will be explained in greater detail the principle of control:

[0117]根据监测的压缩机的电流值区域,确定风机对应的转速并将其切换到对应的转速来实现降低冷凝器的系统压力,达到降低压缩机负荷的目的,同时在切换风机的转速后,持续运行一段时间然后再判断电流的范围是否仍在安全电流值以下,若不是,则按照之前的风速进行运转,直到达到预设值时才将其切换到低风档,这样能防止风机经常切换风速而带来的电流的波动,增加系统的稳定性。 After [0117] The current value of the monitored region of the compressor, the fan is determined corresponding to the rotational speed and the switching speed corresponding condenser system to achieve a reduction in pressure, to reduce the load of the compressor, while the switching speed of the fan , continuous operation for some time and then determine whether the current range is still safe current value, if not, the operation is performed in accordance with the previous wind speed, until when it reaches the preset value will switch to the low windshield, this can often prevent the fan switching current fluctuations caused by wind speed, increasing the stability of the system.

[0118]具体过程包括A〈I<A+Q情形处理过程以及A+2Q>I>A+Q情形处理过程,具体实现如下: [01] The specific process comprises A <I <A + Q as well as the case of process A + 2Q> I> A + Q case process, specifically implemented as follows:

[0119] 1、八<1<八+〇情形处理过程: [0119] 1, eight <1 <+ square case eight processes:

[0120]当压缩机的电流满足A<I〈A+Q时,将所述风机的转速由默认的低风档调整为中风档,其中,A为第一预设阈值,Q为大于或等于1的整数; [0120] When the compressor current satisfies A <I <A + Q, then the fan speed is adjusted by default low stroke speed of the windshield, wherein, A is a first preset threshold, Q is greater than or equal to integer of 1;

[0121] 在除湿机以调节风机转速后持续运行预定时间内,判断压缩机的电流是否小于A+ Q;若是,则 The [0121] After the continuous operation dehumidifier fan speed to adjust the predetermined time, the compressor determines whether the current is less than A + Q; if yes,

[0122] 在除湿机以调节风机转速后持续运行预定时间后,判断压缩机的电流是否小于A 且持续预定时间,若是,则将所述风机的转速调整为低风档;若否,则除湿机继续运行,直到判断压缩机的电流低于A且持续预定时间,并将所述风机的转速调整为低风档。 [0122] After the continuous operation for a predetermined time after the dehumidifier to adjust the fan speed, the compressor determines whether the current is less than a predetermined time A and, if yes, the fan speed is adjusted to a low wind speed; if not, then the dehumidification machine continues running until the compressor is lower than the determination current, and a for a predetermined time, and the low fan speed is adjusted to the windshield.

[0123] 2、A+2Q>I>A+Q 情形处理过程: [0123] 2, A + 2Q> I> A + Q processing situations:

[0124] 当所述压缩机的电流满足A+2Q>I>A+Q时,将所述风机的转速调整为高风档; [0124] When the current of the compressor satisfies A + 2Q> I> A + Q, then the fan speed is adjusted to a high wind speed;

[0125] 在除湿机以调节风机转速后持续运行预定时间内,判断压缩机的电流是否小于A+ 2Q;若是,则在除湿机以调整风机转速后持续运行预定时间后,判断压缩机的电流是否小于A+Q且持续预定时间,若是,且A<I<A+Q,则按前述A<I<A+Q的情形处理过程,若I <A且持续预定时间,则将所述风机的转速调整为低风档;若压缩机的电流大于A+Q,则除湿机继续运行, 直到判断压缩机的电流低于A+Q或A且持续预定时间,并将所述风机的转速调整为中风档或低风档。 [0125] After the dehumidifier fan speed adjustment within a predetermined time of continuous operation, the compressor determines whether the current is less than A + 2Q; after a predetermined time after continuous operation if, at the dehumidifier to adjust the fan speed, the compressor determines whether the current and less than a + Q for a predetermined time, if, and a <I <a + Q, press the a <I <a + Q processing case, if I <a, and for a predetermined time, then the wind turbine a low rotational speed adjustment of the windshield; if the compressor is greater than the current a + Q, the dehumidifier to continue running until the compressor is lower than the determination current or a + Q and a for a predetermined time, and to adjust the speed of the fan is stroke or low profile windshield.

[0126] 此外,当监测到压缩机的电流达到第二预设阈值B (B>A+2Q)时,停止压缩机运行, 并将所述风机的转速调整为高风档;在压缩机关闭设定时间后,重新启动压缩机,同时监测压缩机的电流,重复上述具有三档过程中根据压缩机的电流控制风机的转速的过程。 [0126] Further, when the monitored current reaches a second compressor preset threshold value B (B> A + 2Q), the compressor is stopped operating, and the fan speed is adjusted to a high wind speed; off the compressor after a set time, restart the compressor, the compressor while monitoring current, the process is repeated with third gear control during the current speed of the fan according to the compressor.

[0127] 另外,当监测到环境温度未达到预设值时,若监测到压缩机的电流A<I<B,将所述风机的转速调整为中风档或高风档,持续预定时间后,若监测到压缩机的电流不低于A,则停止压缩机运行;若监测到压缩机的电流I<A,将所述风机的转速保持默认的低风档。 [0127] Further, when the monitored temperature does not reach the predetermined value, when the monitored current compressor A <I <B, the fan speed is adjusted to a stroke speed or high wind speed, for a predetermined time, If the monitored current is not lower than the compressor a, the operation of the compressor is stopped; the compressor if the monitored current I <a, the fan speed to keep the default low windshield.

[0128] 具体实例如下: [0128] Specific examples are as follows:

[0129]当环境温度T>=M度时,发现压缩机电流I高于警戒值A但没有超过压缩机极限值B 时,其中A和B的取值可以根据实际情况进行定义,如:A为[6,15],B为[10,20],具体可为A = 6,B=10;SA=11,B=17;SA=15,B = 20: [0129] When the ambient temperature T> = M degrees, I found compressor current guard value A but higher than the compressor does not exceed the limit value B, wherein A and B values ​​can be defined according to the actual situation, such as: A to [6,15], B is [10,20], may be particularly A = 6, B = 10; SA = 11, B = 17; SA = 15, B = 20:

[0130] 步骤1、电流在A<I<A+Q【Q的取值范围为[1,3]】时,本实施例中Q=2,启动控制器控制风机切换成中风档,实时监控压缩机电流,连续预定时间一C【C的取值范围为[10,18]】分钟内电流小于A+Q,且每隔一分钟将监控电流与上一分钟电流比较,C分钟内,后者都比前者小,则C分钟后判断电流是否到达A以下,如果到达则运行上述C分钟后再次判断是否连续预定时间一D分钟【D的取值范围为[2,5]】分钟内低于A电流。 When [0130] Step 1, a current A <I <A + Q Q ranges [[1,3]], in the present embodiment Q = 2, the controller controls the fan switch to start the stroke speed, real-time monitoring compressor current, a continuous predetermined time range {C C is [10, 18] min] within the current of less than a + Q, every one minute and the monitoring current is compared with a minute current C within minutes, who are smaller than the former, the C min is determined whether the current reaches a or less, if the arrival run above C min is determined again whether a continuous predetermined time D min D is in the range [[2,5]] low within minutes A current in. 低于则切换成低风档运行,高于则重复运行预定时间C分钟,直到低于A电流,切换成低风档运行;若C分钟内后者都比前者大或者C分钟内有电流超过A+Q,则C分钟后风机切换成高风档持续运行,然后每隔一分钟将监控电流与上一分钟电流比较,如果C分钟内后者都比前者小,则C分钟后判断电流是否到达A以下,如果到达则运行C分钟后,再次判断是否连续D分钟内低于A电流。 Below is switched to a low speed operation of wind, a predetermined time is higher than the C min run repeatedly, until the current is less than A, the switching operation to the low wind speed; C within minutes if the latter are larger than the former or current than the C min a + Q, the fan is switched to the C min windshield high continuous operation, and then every minute to monitor the current of the current is compared with a minute, if the latter are smaller than the former C min, the C min is determined whether the current A reaches the following, if, after reaching C min run, again determines whether the current is less than A min D continuously. 高于A且小于B则重复运行C分钟,直到连续D分钟内低于A电流,切换成低风档运行,若高于B,则进入步骤3。 A greater than B and less than the C min run repeatedly until the continuous current is less than D A min, operation is switched to the low air speed, if higher than B, the process proceeds to step 3. [0131] 步骤2、如果电流在A+2Q>I>A+Q。 [0131] Step 2, if the current A + 2Q> I> A + Q. 其中Q = 2,启动控制器控制风机切换成高风档,实时监控压缩机电流,连续C分钟内电流没有超过A+2Q,且每隔一分钟将监控电流与上一分钟电流比较,C分钟内后者都比前者小,则C分钟后判断电流是否到达A+Q以下,如果到达则运行C分钟后再次判断是否低于A+Q电流。 Where Q = 2, the fan controller controls the switch to start the high wind speed, real-time monitoring compressor current, the current does not exceed consecutive minutes C A + 2Q, and every minute to monitor a minute current comparison with current, C min the latter are smaller than the former, the C min is determined whether the current reaches the A + Q, if the operation after reaching C min is determined again whether the current is less than A + Q. 如果电流在A< I <A+Q则执行步骤1,如果电流在连续D 分钟内I<A,低于则切换成低风档运行;如连续D分钟内B>I>A则重复运行C分钟,直到连续D 分钟内低于A电流;若C分钟内后者都比前者大,持续高风档运转。 If the current A <I <A + Q in step 1 is performed, if the current consecutive minutes in D I <A, below is switched to a low speed operation of wind; D within such consecutive minutes B> I> A repeat run C minutes, until the A continuous current is less than D min; C within minutes if the latter are larger than the former, sustained high speed operation of the wind. 继续监控电流,如果持续D 分钟BF>I>B-2F【本实施方式中F=l】,停止压缩机运行。 It continues to monitor current, if the duration D min BF> I> B-2F [the present embodiment] F = l, the compressor stops operation. 持续高风运行,压缩机关闭E分钟【E的取值范围为[30,45]】后启动压缩机同时监控压缩机电流,重复上述的步骤1_3的控制。 Sustained high wind operation range of the compressor close E is [[30, 45]] E min while monitoring the starting of the compressor compressor current, repeating the above step of controlling 1_3.

[0132] 步骤3、当监控压缩机电流超过B时,停止压缩机运行。 [0132] Step 3, when the compressor is monitored current exceeds B, the compressor stops operation. 持续高风档运行,压缩机关闭E分钟后,启动压缩机同时监控压缩机电流,重复上述步骤1-3控制过程。 After continuing to run high windshield, E min compressor off, the compressor is started while monitoring compressor current, repeating steps 1-3 above control process.

[0133] 当环境温度T<M度时,监测到压缩机电流I高于第一预设阈值A但没有超过压缩机第二阈值B时,切换风机持续高风运行,监控电流在A<I时,持续预定时间(如10分钟)后,连续预设时间(如2分钟)内电流不低于A电流。 [0133] When the ambient temperature T <M degrees, monitor the current I of the compressor is higher than a first preset threshold value A, but the compressor does not exceed the second threshold value B, the switching sustained high wind turbine operation, monitoring a current A <I after time, for a predetermined time (e.g. 10 minutes), successive predetermined time (e.g., 2 minutes) is not less than the current A current. 则停止压缩机运行,持续高风档运行并且发出警报,发出错误代码,若检测到I〈A时,切换到低风运行,这样能检测到压缩机刚启动时电流波动的情况。 Compressor operation is stopped, and the operation of the windshield sustained high alarm, an error code is issued, if detected I <A, switch to a low wind operation, such cases can be detected when the compressor has just started the current ripple.

[0134] 本实施方式中,高风档运行可以指风速为800—1000转;高风档与中风档,以及中风档与低风档相差150-250转。 [0134] In the present embodiment, it may refer to operation of the windshield high wind speed of 800-1000 rpm; high stroke speed and wind speed, and wind speed and a low speed stroke, a difference of 150-250 rpm.

[0135] 第二种实施方式:风机可在预设阈值范围内根据检测的电流范围值调节转速。 [0135] The second embodiment: the fan speed can be adjusted according to the detected current range within a preset threshold range. 即通过监测到的压缩机的电流与预设阈值进行比较确定风机转速的调节量;根据风机转速的调节量对风机的转速进行调节直到压缩机的电流值达到预设值以下为止。 Namely amount adjusting fan speed is determined by comparing the monitored current with a preset threshold value of the compressor; of the fan speed is adjusted until the current value of the compressor reaches a preset value or less according to the amount of adjustment of the fan speed.

[0136]具体实现如下:将监测到的所述压缩机的电流与预设阈值进行比较;当监测到的所述压缩机的电流在第一预设阈值A与第二预设阈值B之间时,根据监测到的压缩机的电流,查找预设的公式表,获取风机对应的电压值的调节量AU,进而获取风机对应的电压值U =UA+AU;UA为压缩机的电流为第一预设阈值A时对应的风机的电压值;调整风机的电压至所述获取的对应的电压值,控制所述风机的转速直到压缩机的电流值达到预设值以下为止。 [0136] embodied as follows: a current with a preset threshold value monitored by comparing the compressor; when the monitored current between said compressor in a first predetermined threshold value A and the second predetermined threshold value B when, in accordance with the monitored current of the compressor, a preset lookup table formulas, AU obtain the adjustment amount corresponding to the voltage value of the fan, the fan and thus acquires a voltage value corresponding to U = UA + AU; UA current for the first compressor a preset voltage corresponding to the threshold value a fan; adjusting a voltage corresponding to the fan voltage value to the acquired fan rotation speed of the control value of the compressor until the current reaches a preset value or less.

[0137]例如,将压缩机电流在第一预设阈值A与压缩机第二预设阈值(极限值)B之间,每增加1安培电流确定对应风机的电压值,g卩,基于压缩机电流与风机的电压值建立一公式表,该公式表中,由电流为第一预设阈值A对应一风机电压值开始,每增加1安培电流确定有对应风机的电压值,在监测到压缩机电流后,查找该公示表,即可得到风机对应的电压值, 调整风机的电压至对应的电压值,控制风机的转速,由此,通过调节电机的电压控制风机的转速,从而根据电流值精确地调节风机转速。 [0137] For example, the compressor current between a first predetermined threshold value A and the compressor of the second predetermined threshold value (limit value) B, every increase of 1 ampere corresponding to the fan voltage value is determined, g Jie, the compressor based on current and voltage values ​​to establish a formula for fan table, the table formulas, a corresponds to a first predetermined threshold value starts a fan voltage by the current, for every increase of 1 ampere corresponding to a voltage value determined to the fan, the compressor monitoring after the current, the publicity lookup table, to obtain a voltage value corresponding to the wind turbine, adjust the voltage value corresponding to the fan, fan speed control, whereby the speed of the fan motor is controlled by adjusting the voltage, the current value to precisely adjust the fan speed.
