对于一些湿度比较高的环境，仅仅根据温度来对空调进行控制，还很难满足用户对空调作用区域中空气舒适度的要求。本发明实施例中，空调可以根据作用区域内的当前湿度值，以及目标湿度值，进行PID控制运算，确定压缩机的工作频率，从而对空调的压缩机进行控制，这样，不仅进一步提高了空调控制的针对性以及精确性，并且，对于湿度比较高的环境，由于空调会根据湿度调节压缩机的工作频率，可有效调节作用区域内的湿度，改善作用区域内的空气舒适度。For some environments with relatively high humidity, it is difficult to control the air conditioner only according to the temperature, and it is difficult to meet the user's requirements for air comfort in the air conditioner area. In the embodiment of the present invention, the air conditioner can perform a PID control operation according to the current humidity value in the action area and the target humidity value, and determine the operating frequency of the compressor, so as to control the compressor of the air conditioner. In this way, not only the air conditioner is further improved The pertinence and accuracy of the control, and for the environment with relatively high humidity, because the air conditioner will adjust the operating frequency of the compressor according to the humidity, it can effectively adjust the humidity in the active area and improve the air comfort in the active area.

空调有多种运行模式，例如：除湿模式、制冷模式、制热模式等等，无论空调处于何种模式，都可根据作用区域内的当前湿度值，以及目标湿度值，进行PID控制运算，确定压缩机的工作频率，从而对空调的压缩机进行控制。具体可包括：获取空调作用区域内的当前湿度值，并得到当前湿度值与目标湿度值之间的当前绝对湿度差值；当当前绝对湿度差值满足与空调的运行模式匹配的设定条件时，可根据当前绝对湿度差值，进行当前次数的PID控制运算，获得PID输出量；根据空调的运行模式及其对应的压缩机的最大工作频率、获取的压缩机的实际返回工作频率，以及PID控制对应的次数，确定与当前绝对湿度差值对应的压缩机的第一工作频率；然后，根据PID输出量对第一工作频率进行修正，得到压缩机的当前工作频率，并控制压缩机根据当前工作频率进行运行。其中，运行模式包括：除湿模式、制冷模式、或、制热模式。The air conditioner has a variety of operating modes, such as dehumidification mode, cooling mode, heating mode, etc. No matter what mode the air conditioner is in, it can perform PID control operation according to the current humidity value in the action area and the target humidity value to determine The operating frequency of the compressor is used to control the compressor of the air conditioner. Specifically, it may include: acquiring the current humidity value in the air conditioner operating area, and obtaining the current absolute humidity difference value between the current humidity value and the target humidity value; when the current absolute humidity difference value satisfies the set condition matching the operation mode of the air conditioner , according to the current absolute humidity difference, the current number of PID control operations can be performed to obtain the PID output; according to the operating mode of the air conditioner and its corresponding maximum operating frequency of the compressor, the obtained actual return operating frequency of the compressor, and the PID Control the corresponding times to determine the first working frequency of the compressor corresponding to the current absolute humidity difference; then, correct the first working frequency according to the PID output to obtain the current working frequency of the compressor, and control the compressor according to the current operating frequency. The operation modes include: dehumidification mode, cooling mode, or heating mode.

本发明实施例中，具体描述空调处于制冷模式时，可根据作用区域内的当前湿度值，以及目标湿度值，进行PID控制运算，确定压缩机的工作频率，从而对空调的压缩机进行控制。In the embodiment of the present invention, it is specifically described that when the air conditioner is in the cooling mode, the PID control operation can be performed according to the current humidity value in the action area and the target humidity value to determine the operating frequency of the compressor, so as to control the compressor of the air conditioner.

图1是根据一示例性实施例示出的一种空调控制方法的流程图。如图1所示，空调控制的过程包括：FIG. 1 is a flow chart of an air conditioning control method according to an exemplary embodiment. As shown in Figure 1, the process of air conditioning control includes:

步骤101：获取处于制冷模式的空调作用区域内的当前湿度值，并得到当前湿度值与目标湿度值之间的当前绝对湿度差值。Step 101: Acquire the current humidity value in the air conditioner operating area in the cooling mode, and obtain the current absolute humidity difference between the current humidity value and the target humidity value.

本发明实施例中，空调对应的工作模式已经设置为制冷模式，即空调可能将进入制冷模式，或者已经处于制冷模式运行了。In the embodiment of the present invention, the working mode corresponding to the air conditioner has been set to the cooling mode, that is, the air conditioner may enter the cooling mode, or is already running in the cooling mode.

此时，可获取空调作用区域内的当前湿度值，对应的方式可以有多种，例如：通过湿度传感器获取作用区域内的当前湿度值，或者，通过作用区域内的温度值，盘管温度值以及压缩机的工作频率等计算获得当前湿度值。At this time, the current humidity value in the air-conditioning area can be obtained, and the corresponding methods can be various, for example: obtaining the current humidity value in the operation area through a humidity sensor, or, through the temperature value in the operation area, the coil temperature value As well as the operating frequency of the compressor and other calculations to obtain the current humidity value.

当然，预先配置了一个目标湿度值，该目标湿度值可用户手动设置，也可根据空调所处的地域、当前季节等等进行配置后，空调根据配置获得。Of course, a target humidity value is pre-configured, and the target humidity value can be manually set by the user, or can be configured according to the region where the air conditioner is located, the current season, etc., and the air conditioner can be obtained according to the configuration.

已知了当前湿度值和目标湿度值之后，即可得到当前湿度值与目标湿度值之间的当前绝对湿度差值，即当前绝对湿度差值Pn＝Ⅰ当前湿度值-目标湿度值Ⅰ。其中，n为PID控制对应的次数，从0开始，每次逐渐加1，即n＝0、1、2…等这样的整数。After the current humidity value and the target humidity value are known, the current absolute humidity difference value between the current humidity value and the target humidity value can be obtained, that is, the current absolute humidity difference value Pn=I current humidity value-target humidity value I. Among them, n is the number of times corresponding to PID control, starting from 0 and gradually increasing by 1 each time, that is, integers such as n=0, 1, 2, etc.

步骤102：当当前绝对湿度差值满足与空调的制冷模式匹配的设定条件时，根据当前绝对湿度差值，进行当前次数的比例积分微分PID控制运算，获得PID输出量。Step 102: When the current absolute humidity difference satisfies the set condition matching the cooling mode of the air conditioner, perform the current number of proportional integral derivative PID control operations according to the current absolute humidity difference to obtain the PID output.

由于空调已被设置为制冷模式了，由于制冷模式下都可进行PID控制，那么，若当前绝对湿度差大于零时，即可进行本发明实施例中的PID(比例(proportion)、积分(integral)、微分(derivative))控制。Since the air conditioner has been set to the cooling mode, and the PID control can be performed in the cooling mode, then, if the current absolute humidity difference is greater than zero, the PID (proportion), integral (integral) in the embodiment of the present invention can be performed ), derivative (derivative) control.

即当前绝对湿度为绝对值，大于零，即可确定当前绝对湿度差值满足与空调的制冷模式匹配的设定条件。此时，可根据当前绝对湿度差值，进行当前次数的比例积分微分PID控制运算，获得PID输出量，较佳地，可包括：根据当前绝对湿度差值，保存的前一次绝对温差值，以及保存的前两次绝对温差值，对PID控制运算中的比例参数、积分参数、以及微分参数进行修正，获得修正比例参数、修正积分参数、以及修正微分参数；根据修正比例参数、修正积分参数、以及修正微分参数对PID控制的输出状态值进行修正，得到当前输出量；以及，根据当前输出量，以及保存的前次输出量，得到PID输出量。That is, the current absolute humidity is an absolute value, which is greater than zero, and it can be determined that the current absolute humidity difference satisfies the set condition matching the cooling mode of the air conditioner. At this time, according to the current absolute humidity difference, the current number of proportional integral derivative PID control operations can be performed to obtain the PID output. The saved absolute temperature difference values of the first two times are used to correct the proportional parameters, integral parameters and differential parameters in the PID control operation to obtain the revised proportional parameters, the revised integral parameters and the revised differential parameters; according to the revised proportional parameters, revised integral parameters, and correcting the differential parameter to correct the output state value of the PID control to obtain the current output; and, according to the current output and the saved previous output, to obtain the PID output.

本实施中，获得了当前绝对湿度差Pn后即可进行保存，这样，保存了每次PID控制对应的当前绝对湿度差Pn，从而，前一次绝对温差值可为Pn-1，而前两次绝对温差值可为Pn-2。In this implementation, after the current absolute humidity difference Pn is obtained, it can be saved. In this way, the current absolute humidity difference Pn corresponding to each PID control is saved. Therefore, the previous absolute temperature difference value can be Pn-1, and the previous two absolute temperature difference values can be Pn-1. The absolute temperature difference can be Pn-2.

因此，可设定当次偏差Wn＝|设定湿度-室内湿度|*10＝Pn*10；则前一次偏差Wn-1＝Pn-1*10，前两次偏差Wn-2＝Pn-2*10。从而，当次偏差的差Dn＝Wn–Wn-1，而前一次偏差的差Dn-1＝Wn-1–Wn-2。Therefore, the current deviation Wn=|set humidity-indoor humidity|*10=Pn*10 can be set; the previous deviation Wn-1=Pn-1*10, the previous two deviations Wn-2=Pn-2 *10. Thus, the difference of the current deviation Dn=Wn−Wn−1, and the difference of the previous deviation Dn−1=Wn−1−Wn−2.

由于需根据湿度进行PID控制运算，因此，PID控制中，比例控制量Hzkp，积分控制量Hzki，微分控制量Hzkd，输出补正后的输出量Hzout，而前一次输出补正后的输出量Hzout1，从而，过滤后的输出量Hzoutf，本实施例中，过滤后的输出量Hzoutf即可为PID输出量。Since the PID control operation needs to be performed according to the humidity, in the PID control, the proportional control amount Hzkp, the integral control amount Hzki, the differential control amount Hzkd, the output corrected output Hzout, and the corrected output Hzout1 of the previous output, thus , the filtered output Hzoutf, in this embodiment, the filtered output Hzoutf can be the PID output.

其中，PID控制运算可包括：Among them, the PID control operation can include:

Hzkp＝Kp*Dn；Hzkp=Kp*Dn;

Hzki＝Ki*Wn；Hzki=Ki*Wn;

Hzkd＝Kd*(Dn－Dn-1)；Hzkd=Kd*(Dn-Dn-1);

ΔFn＝Hzkp+Hzki+Hzkd；ΔFn=Hzkp+Hzki+Hzkd;

Hzout＝Out_gain*ΔFn；Hzout=Out_gain*ΔFn;

Hzoutf＝(Hzout+(Hzout1*2))/3。Hzoutf=(Hzout+(Hzout1*2))/3.

可见，通过上述的PID控制运算，可得到与当前绝对湿度差值对应的PID输出量Hzoutf。It can be seen that through the above PID control operation, the PID output Hzoutf corresponding to the current absolute humidity difference can be obtained.

步骤103：根据空调的制冷模式及其对应的压缩机的最大工作频率、获取的压缩机的实际返回工作频率，以及PID控制对应的次数，确定与当前绝对湿度差值对应的压缩机的第一工作频率。Step 103: According to the refrigeration mode of the air conditioner and the maximum operating frequency of the corresponding compressor, the obtained actual return operating frequency of the compressor, and the number of times corresponding to the PID control, determine the first compressor corresponding to the current absolute humidity difference. working frequency.

由于本发明实施例中，是通过PID运算对压缩机的工作频率进行控制，具体地，根据PID输出量Hzoutf对压缩机某个工作频率进行修正，即根据PID输出量Hzoutf对压缩机的第一工作频率进行修正。而压缩机的第一工作频率可根据空调的不同运行情况，不完全相同，因此，需根据空调的制冷模式及其对应的压缩机的最大工作频率、获取的压缩机的实际返回工作频率，以及PID控制对应的次数，确定与当前绝对湿度差值对应的压缩机的第一工作频率Sn。Because in the embodiment of the present invention, the operating frequency of the compressor is controlled by PID operation, and specifically, a certain operating frequency of the compressor is corrected according to the PID output Hzoutf, that is, the first operating frequency of the compressor is adjusted according to the PID output Hzoutf. The working frequency is corrected. The first operating frequency of the compressor may not be exactly the same according to the different operating conditions of the air conditioner. Therefore, it needs to be determined according to the cooling mode of the air conditioner and its corresponding maximum operating frequency of the compressor, the obtained actual return operating frequency of the compressor, and The number of times corresponding to the PID control is used to determine the first operating frequency Sn of the compressor corresponding to the current absolute humidity difference.

本实施例中，空调进入制冷模式后，每进行一次PID控制，PID控制对应的次数可需加1，即PID控制对应的次数n从0开始，每次逐渐加1。一般，n>0时，即连续进行PID控制后，可将获取的压缩机的实际返回工作频率确定为第一工作频率Sn。但是，n＝0时，即当PID控制对应的次数为零次时，确定与当前绝对湿度差值对应的压缩机的第一工作频率的确定方式可包括：当空调的压缩机以制冷模式的最大工作频率启动运行，且当前绝对湿度差值小于或等于第一设定值的时间超过设定时长时，将获取的压缩机的实际返回工作频率确定为第一工作频率；当空调的压缩机未在制冷模式下运行，且当前绝对湿度差值小于或等于第一设定值并大于第二设定值时，将最大工作频率的第一设定比例值，确定为第一工作频率。当空调的压缩机未在制冷模式下运行，且当前绝对湿度差值小于或等于第二设定值时，将最大工作频率的第二设定比例值，确定为第一工作频率；其中，第一设定值大于第二设定值，第一设定比例值大于第二设定比例值。In this embodiment, after the air conditioner enters the cooling mode, each time the PID control is performed, the number of times corresponding to the PID control may need to be increased by 1, that is, the number of times n corresponding to the PID control starts from 0, and gradually increases by 1 each time. Generally, when n>0, that is, after continuous PID control, the acquired actual return operating frequency of the compressor may be determined as the first operating frequency Sn. However, when n=0, that is, when the number of times corresponding to the PID control is zero, the method for determining the first operating frequency of the compressor corresponding to the current absolute humidity difference may include: when the compressor of the air conditioner operates in the cooling mode When the maximum working frequency starts running, and the time when the current absolute humidity difference is less than or equal to the first set value exceeds the set time period, the obtained actual return working frequency of the compressor is determined as the first working frequency; when the compressor of the air conditioner When not operating in the cooling mode, and the current absolute humidity difference is less than or equal to the first set value and greater than the second set value, the first set proportional value of the maximum working frequency is determined as the first working frequency. When the compressor of the air conditioner is not running in the cooling mode, and the current absolute humidity difference is less than or equal to the second set value, the second set proportional value of the maximum working frequency is determined as the first working frequency; A set value is greater than the second set value, and the first set ratio value is greater than the second set ratio value.

例如：第一设定值为30，第二设定值为10，第一设定比例值为70％，第二设定比例值为50％。这样，空调首次上电开机，或者，空调进行了模式切换，刚切换到制冷模式，或者，空调关机后再次开机，此时，空调都未在制冷模式下运行，也未进行PID控制，即PID控制对应的次数n为零，若P0>30，可能湿度比较大，此时，空调的压缩机需立刻制冷模式的最大工作频率启动运行，这样，才能最大可能降低环境中湿度，使得湿度值慢慢下降，这样，当空调的压缩机以制冷模式的最大工作频率启动运行，且当前绝对湿度差值若P0≤30的时间超过设定时长，例如超过50秒，这样，可直接将获取的压缩机的实际返回工作频率确定为第一工作频率Sn。For example: the first set value is 30, the second set value is 10, the first set ratio value is 70%, and the second set ratio value is 50%. In this way, the air conditioner is powered on for the first time, or the air conditioner has switched the mode and just switched to the cooling mode, or the air conditioner is turned off and then turned on again. At this time, the air conditioner is not running in the cooling mode, nor does PID control, that is, PID control. The corresponding number of control n is zero. If P0>30, the humidity may be relatively high. At this time, the compressor of the air conditioner needs to start running at the maximum operating frequency of the cooling mode immediately. In this way, the humidity in the environment can be reduced to the greatest extent possible, so that the humidity value is slow. In this way, when the compressor of the air conditioner starts to run at the maximum operating frequency of the cooling mode, and if the current absolute humidity difference value P0≤30 exceeds the set time, for example, more than 50 seconds, the obtained compressed air can be directly The actual return operating frequency of the machine is determined as the first operating frequency Sn.

或者，空调首次上电开机，或者，空调进行了模式切换，刚切换到制冷模式，或者，空调关机后再次开机，此时，空调都未在制冷模式下运行，也未进行PID控制，即PID控制对应的次数n为零，若10<P0≤30时，可直接将最大工作频率的70％确定为第一工作频率Sn。Or, the air conditioner is powered on for the first time, or the air conditioner has switched modes and has just switched to the cooling mode, or the air conditioner has been turned off and turned on again. At this time, the air conditioner is not running in the cooling mode and does not perform PID control, that is, PID control. The number n corresponding to the control is zero. If 10<P0≤30, 70% of the maximum operating frequency can be directly determined as the first operating frequency Sn.

或者，空调首次上电开机，或者，空调进行了模式切换，刚切换到制冷模式，或者，空调关机后再次开机，此时，空调都未在制冷模式下运行，也未进行PID控制，即PID控制对应的次数n为零，若P0≤10时，可直接将最大工作频率的50％确定为第一工作频率Sn。Or, the air conditioner is powered on for the first time, or the air conditioner has switched modes and has just switched to the cooling mode, or the air conditioner has been turned off and turned on again. At this time, the air conditioner is not running in the cooling mode and does not perform PID control, that is, PID control. The number n corresponding to the control is zero, and if P0≤10, 50% of the maximum operating frequency can be directly determined as the first operating frequency Sn.

步骤104：根据PID输出量对第一工作频率进行修正，得到压缩机的当前工作频率，并控制压缩机根据当前工作频率进行运行。Step 104: Correct the first working frequency according to the PID output to obtain the current working frequency of the compressor, and control the compressor to operate according to the current working frequency.

本实施例中，Fn＝Sn+Hzoutf，其中，Fn为当前工作频率，Sn为第一工作频率，Hzoutf为PID输出量。即当前工作频率是根据第一工作频率以及Hzoutf确定的。因此，步骤102中获得PID输出量，与步骤103中确定第一工作频率的先后顺序可以变化，即当当前绝对湿度差值满足与空调的制冷模式匹配的设定条件时，可先确定第一工作频率，再获得PID输出量。In this embodiment, Fn=Sn+Hzoutf, wherein, Fn is the current operating frequency, Sn is the first operating frequency, and Hzoutf is the PID output. That is, the current operating frequency is determined according to the first operating frequency and Hzoutf. Therefore, the order of obtaining the PID output in step 102 and determining the first operating frequency in step 103 can be changed, that is, when the current absolute humidity difference satisfies the set condition matching the cooling mode of the air conditioner, the first Working frequency, and then obtain PID output.

得到当前工作频率Sn，即可控制压缩机根据当前工作频率进行运行。By obtaining the current operating frequency Sn, the compressor can be controlled to operate according to the current operating frequency.

可见，本发明实施例中，处于制冷模式的空调，可以根据作用区域内的当前湿度值，以及目标湿度值，进行PID控制运算，确定压缩机的工作频率，从而对空调的压缩机进行控制，这样，不仅进一步提高了空调控制的针对性以及精确性，并且，对于湿度比较高的环境，由于空调会根据湿度调节压缩机的工作频率，可有效调节作用区域内的湿度，改善作用区域内的空气舒适度。It can be seen that, in the embodiment of the present invention, the air conditioner in the cooling mode can perform PID control operation according to the current humidity value in the action area and the target humidity value to determine the operating frequency of the compressor, so as to control the compressor of the air conditioner. In this way, not only the pertinence and accuracy of air-conditioning control are further improved, but also for environments with relatively high humidity, since the air-conditioning will adjust the operating frequency of the compressor according to the humidity, the humidity in the action area can be effectively adjusted and the humidity in the action area can be improved. Air comfort.

例如：空调刚切换到制冷模式，那么，n＝0，获取当前湿度值后，得到的当前绝对湿度差值P0>30，从而，空调的压缩机以制冷模式的最大工作频率启动运行，并当P0≤30的时间超过设定时间例如40s后，可将获取的压缩机的实际返回工作频率确定为第一工作频率S0，并且，n＝0，从而，前一次绝对温差值，前两次绝对温差值都没有，即可为0，同样，前一次输出补正后的输出量Hzout1也没有，此时，Hzoutf＝0，然后，当前工作频率F0＝S0+0，即n＝0时，F0＝S0，则可控制压缩机根据当前工作频率进行运行。For example: the air conditioner has just switched to the cooling mode, then, n=0, after obtaining the current humidity value, the obtained current absolute humidity difference value P0>30, thus, the compressor of the air conditioner starts to run at the maximum working frequency of the cooling mode, and when After the time of P0≤30 exceeds the set time, such as 40s, the obtained actual return operating frequency of the compressor can be determined as the first operating frequency S0, and n=0, so the absolute temperature difference value of the previous time, absolute temperature difference value of the previous two times can be determined as the first operating frequency S0. If there is no temperature difference value, it can be 0. Similarly, the output value Hzout1 after the previous output correction is also not available. At this time, Hzoutf=0, then, the current operating frequency F0=S0+0, that is, when n=0, F0= S0, the compressor can be controlled to run according to the current operating frequency.

本次PID控制运行后，PID控制对应的次数需要加1，即n＝1，此时，由于空调已经处于制冷模式运行了，当P1>0,且n>0，从而可将获取的压缩机的实际返回工作频率确定为第一工作频率S1，而此时，根据步骤102中的公式，可获得Hzoutf，然后，当前工作频率F1＝S1+Hzoutf，即控制压缩机根据当前工作频率进行运行。以此，继续PID控制运行下去。After this PID control operation, the number of times corresponding to the PID control needs to be increased by 1, that is, n=1. At this time, since the air conditioner is already running in the cooling mode, when P1>0, and n>0, the obtained compressor can be The actual return operating frequency of 1 is determined as the first operating frequency S1, and at this time, according to the formula in step 102, Hzoutf can be obtained, and then the current operating frequency F1=S1+Hzoutf, that is, the compressor is controlled to operate according to the current operating frequency. In this way, the PID control operation is continued.

或者，空调刚切换到制冷模式，那么，n＝0，获取当前湿度值后，得到的当前绝对湿度差值P0>0，满足与空调的制冷模式匹配的设定条件，并且，10<P0≤30，此时，将最大工作频率的70％，确定为第一工作频率，n＝0，根据步骤102中的公式，可获得Hzoutf＝0，然后，当前工作频率F0＝S0+0，即控制压缩机根据当前工作频率进行运行。而本次PID控制运行后，PID控制对应的次数需要加1，即n＝1，此时，P1>0,且n>0，从而可将获取的压缩机的实际返回工作频率确定为第一工作频率S1，而此时，根据步骤102中的公式，可获得Hzoutf，然后，当前工作频率F1＝S1+Hzoutf，即控制压缩机根据当前工作频率进行运行。以此，继续PID控制运行下去。Or, the air conditioner has just switched to the cooling mode, then, n=0, after obtaining the current humidity value, the obtained current absolute humidity difference value P0>0 satisfies the setting condition matching the cooling mode of the air conditioner, and 10<P0≤ 30. At this time, 70% of the maximum operating frequency is determined as the first operating frequency, n=0, according to the formula in step 102, Hzoutf=0 can be obtained, then, the current operating frequency F0=S0+0, that is, the control The compressor operates according to the current operating frequency. After this PID control operation, the number of times corresponding to the PID control needs to be increased by 1, that is, n=1. At this time, P1>0, and n>0, so that the obtained actual return operating frequency of the compressor can be determined as the first The working frequency S1, and at this time, according to the formula in step 102, Hzoutf can be obtained, and then the current working frequency F1=S1+Hzoutf, that is, the compressor is controlled to operate according to the current working frequency. In this way, the PID control operation is continued.

或者，空调刚切换到制冷模式，那么，n＝0，获取当前湿度值后，得到的当前绝对湿度差值P0>0，满足与空调的制冷模式匹配的设定条件，并且，P0≤10，此时，将最大工作频率的50％，确定为第一工作频率，n＝0，根据步骤102中的公式，可获得Hzoutf＝0，然后，当前工作频率F0＝S0+0，即控制压缩机根据当前工作频率进行运行。而本次PID控制运行后，PID控制对应的次数需要加1，即n＝1，此时，P1>0,且n>0，从而可将获取的压缩机的实际返回工作频率确定为第一工作频率S1，而此时，根据步骤102中的公式，可获得Hzoutf，然后，当前工作频率F1＝S1+Hzoutf，即控制压缩机根据当前工作频率进行运行。以此，继续PID控制运行下去。Or, the air conditioner has just switched to the cooling mode, then, n=0, after obtaining the current humidity value, the obtained current absolute humidity difference value P0>0, which satisfies the setting condition matching the cooling mode of the air conditioner, and, P0≤10, At this time, 50% of the maximum operating frequency is determined as the first operating frequency, n=0, according to the formula in step 102, Hzoutf=0 can be obtained, then, the current operating frequency F0=S0+0, that is, the compressor is controlled Run according to the current operating frequency. After this PID control operation, the number of times corresponding to the PID control needs to be increased by 1, that is, n=1. At this time, P1>0, and n>0, so that the obtained actual return operating frequency of the compressor can be determined as the first The working frequency S1, and at this time, according to the formula in step 102, Hzoutf can be obtained, and then the current working frequency F1=S1+Hzoutf, that is, the compressor is controlled to operate according to the current working frequency. In this way, the PID control operation is continued.

上述实施例中，n>0时，可将获取的压缩机的实际返回工作频率确定为第一工作频率S1。但是，本发明另一实施例中，当PID控制对应的次数不为零次，确定与当前绝对湿度差值对应的压缩机的第一工作频率还包括：若压缩机在制冷模式下的运行时间小于设定时间，且压缩机的实际返回工作频率小于前一次PID控制的第一工作频率，则将前一次PID控制的第一工作频率确定为本次PID控制的第一工作频率。例如：前一次PID控制的第一工作频率为制冷模式的最大工作频率的70％，而压缩机在制冷模式下的运行时间小于2分钟，并且，实际返回工作频率小于最大工作频率的70％，则仍将最大工作频率的70％确定为本次PID控制的第一工作频率。或者，前一次PID控制的第一工作频率为制冷模式的最大工作频率的50％，而压缩机在制冷模式下的运行时间小于2分钟，并且，实际返回工作频率小于最大工作频率的70％，则仍将最大工作频率的50％确定为本次PID控制的第一工作频率。In the above embodiment, when n>0, the acquired actual return operating frequency of the compressor may be determined as the first operating frequency S1. However, in another embodiment of the present invention, when the number of times corresponding to the PID control is not zero, determining the first operating frequency of the compressor corresponding to the current absolute humidity difference further includes: if the compressor is in the cooling mode, the operating time is less than the set time, and the actual return operating frequency of the compressor is less than the first operating frequency of the previous PID control, then the first operating frequency of the previous PID control is determined as the first operating frequency of the current PID control. For example: the first working frequency of the previous PID control is 70% of the maximum working frequency of the cooling mode, and the running time of the compressor in the cooling mode is less than 2 minutes, and the actual return working frequency is less than 70% of the maximum working frequency, Then 70% of the maximum working frequency is still determined as the first working frequency of this PID control. Or, the first working frequency of the previous PID control is 50% of the maximum working frequency of the cooling mode, and the running time of the compressor in the cooling mode is less than 2 minutes, and the actual return working frequency is less than 70% of the maximum working frequency, Then, 50% of the maximum working frequency is still determined as the first working frequency of this PID control.

当然，本发明另一实施例中，空调也可能是在制冷模式下已经运行了一段时间了，若当前绝对湿度差值满足与空调的运行模式匹配的设定条件时，初始时，PID控制对应的次数为零次，确定与当前绝对湿度差值对应的压缩机的第一工作频率还包括：当空调的压缩机在制冷模式下已运行，且获取的室外温度值小于预设温度值时，将压缩机的最小工作频率确定为第一工作频率；当空调的压缩机在制冷模式下已运行，且获取的室外温度值大于或等于预设温度值时，将最大工作频率的第三设定比例值，确定为第一工作频率，其中，第三设定比例值小于第二设定比例值。Of course, in another embodiment of the present invention, the air conditioner may have been operating in the cooling mode for a period of time. If the current absolute humidity difference satisfies the set condition matching the operating mode of the air conditioner, initially, the PID control corresponds to The number of times is zero, and determining the first operating frequency of the compressor corresponding to the current absolute humidity difference further includes: when the compressor of the air conditioner has been running in the cooling mode and the obtained outdoor temperature value is less than the preset temperature value, Determine the minimum working frequency of the compressor as the first working frequency; when the compressor of the air conditioner has been running in the cooling mode, and the obtained outdoor temperature value is greater than or equal to the preset temperature value, the third setting of the maximum working frequency is set. The proportional value is determined as the first operating frequency, wherein the third preset proportional value is smaller than the second preset proportional value.

例如：空调的感温器为ON，即空调的压缩机在制冷模式下已运行了，进行PID控制时，可根据步骤102中的公式，得到PID输出量，并获取室外温度值Tao，然后，根据室外温度值Tao，确定第一工作频率。For example: the temperature sensor of the air conditioner is ON, that is, the compressor of the air conditioner has been running in the cooling mode. When PID control is performed, the PID output can be obtained according to the formula in step 102, and the outdoor temperature value Tao can be obtained. Then, The first operating frequency is determined according to the outdoor temperature value Tao.

其中，空调上电开机，或者，空调进行了模式切换，刚切换到制冷模式，或者，空调关机后再次开机等等，n＝0。即压缩机首次开启，或者，感温器OFF后再次开启ON，或者，压缩机关闭后再次开启时，都是重新开始PID控制，从而n＝0。由于n＝0，则PID输出量也为零。Wherein, the air conditioner is powered on, or the air conditioner has switched modes and just switched to the cooling mode, or the air conditioner is turned on again after being turned off, and so on, n=0. That is, when the compressor is turned on for the first time, or when the temperature sensor is turned off and then turned on again, or when the compressor is turned off and turned on again, the PID control is restarted, so that n=0. Since n=0, the PID output is also zero.

本发明实施例中，若Tao<设定温度值例如30，可将压缩机的在制冷模式下的最小工作频率确定为第一工作频率，然后，根据PID输出量对第一工作频率进行修正，得到压缩机的当前工作频率，并控制压缩机根据当前工作频率进行运行。而在后需的PID控制中，由于n>0，可将获取的压缩机的实际返回工作频率确定为第一工作频率，进而得到压缩机的当前工作频率并进行控制。而若Tao≥30时，可将最大工作频率的第三设定比例值，确定为第一工作频率。例如：第一工作频率Sn＝最大工作频率*70％*Le,其中，Le一般取值45％，这样，第三设定比例值为31.5％，小于第二设定比例值50％。In the embodiment of the present invention, if Tao< set temperature value, for example, 30, the minimum operating frequency of the compressor in the cooling mode can be determined as the first operating frequency, and then the first operating frequency is corrected according to the PID output, The current operating frequency of the compressor is obtained, and the compressor is controlled to operate according to the current operating frequency. In the PID control required later, since n>0, the acquired actual return operating frequency of the compressor can be determined as the first operating frequency, and then the current operating frequency of the compressor can be obtained and controlled. And if Tao≥30, the third set proportional value of the maximum operating frequency can be determined as the first operating frequency. For example: the first operating frequency Sn=maximum operating frequency*70%*Le, where Le generally takes a value of 45%, so the third set ratio is 31.5%, which is less than 50% of the second set ratio.

下面将操作流程集合到具体实施例中，举例说明本公开实施例提供的控制方法。The operation procedures are grouped into specific embodiments below to illustrate the control methods provided by the embodiments of the present disclosure.

本实施例中，第一设定值为35，第二设定值为15，第一设定比例值为75％，第二设定比例值为50％，第三设定比例值为35％。In this embodiment, the first set value is 35, the second set value is 15, the first set ratio is 75%, the second set ratio is 50%, and the third set ratio is 35% .

图2是根据一示例性实施例示出的一种空调控制方法的流程图。如图2所示，空调控制的过程包括：Fig. 2 is a flow chart of an air conditioning control method according to an exemplary embodiment. As shown in Figure 2, the process of air conditioning control includes:

图5根据一示例性实施例示出的一种空调控制装置的框图。如图5示，该装置可包括：制冷单元100、制冷输出单元200、制冷确定单元300和制冷控制单元400，其中，制冷确定单元300包括：制冷第一确定子单元310、制冷第二确定子单元320、制冷第三确定子单元330、制冷第四确定子单元340和制冷第五确定子单元350。Fig. 5 shows a block diagram of an air conditioner control device according to an exemplary embodiment. As shown in FIG. 5 , the apparatus may include: a cooling unit 100 , a cooling output unit 200 , a cooling determination unit 300 and a cooling control unit 400 , wherein the cooling determination unit 300 includes: a first cooling determination subunit 310 and a second cooling determination subunit 300 unit 320 , a third cooling determination subunit 330 , a fourth cooling determination subunit 340 , and a fifth cooling determination subunit 350 .

这样，制冷获取单元100可先获取处于制冷模式的空调作用区域内的当前湿度值，并得到当前湿度值与目标湿度值之间的当前绝对湿度差值Pn。这样，制冷模式下可以进行PID控制了。制冷输出模块200可根据当前绝对湿度差值，进行当前次数的比例积分微分PID控制运算，获得PID输出量Hzoutf。In this way, the cooling obtaining unit 100 may first obtain the current humidity value in the air-conditioning action area in the cooling mode, and obtain the current absolute humidity difference value Pn between the current humidity value and the target humidity value. In this way, PID control can be performed in cooling mode. The refrigeration output module 200 can perform the current number of proportional-integral-derivative PID control operations according to the current absolute humidity difference to obtain the PID output Hzoutf.

而当PID控制对应的次数n为零次，空调的压缩机以制冷模式的最大工作频率启动运行，且Pn≤30超过设定时长如35s时，制冷第一确定子单元310可将获取的压缩机的实际返回工作频率确定为第一工作频率。When the number n corresponding to the PID control is zero, the compressor of the air conditioner starts to run at the maximum operating frequency of the cooling mode, and when Pn≤30 exceeds the set duration, such as 35s, the cooling first determination sub-unit 310 can The actual return working frequency of the machine is determined as the first working frequency.

当PID控制对应的次数n为零次，空调的压缩机未在制冷模式下运行，Pn≤10时，制冷第三确定子单元330可将最大工作频率的50％，确定为第一工作频率。When the number n corresponding to the PID control is zero, the compressor of the air conditioner is not running in the cooling mode, and Pn≤10, the third cooling determination subunit 330 may determine 50% of the maximum operating frequency as the first operating frequency.

当PID控制对应的次数n为零次，空调的压缩机在制冷模式下已运行，获取的室外温度Tao<设定温度例如30时，制冷第四确定子单元340可将制冷模式下最小工作频率，确定为第一工作频率。而获取的室外温度Tao≥30时，制冷第五确定子单元350可将最大工作频率的31.5％，确定为第一工作频率。When the number n corresponding to the PID control is zero, the compressor of the air conditioner has been running in the cooling mode, and the obtained outdoor temperature Tao < the set temperature, for example, 30, the fourth cooling determination sub-unit 340 can determine the minimum operating frequency in the cooling mode , which is determined as the first operating frequency. When the obtained outdoor temperature Tao≥30, the fifth cooling determination subunit 350 may determine 31.5% of the maximum operating frequency as the first operating frequency.

而当PID控制对应的次数n不为零，即大于零时，制冷确定模块300可直接将压缩机的实际返回工作频率确定为第一工作频率。或者，当PID控制对应的次数不为零次，压缩机在制冷模式下的运行时间小于设定时间，且压缩机的实际返回工作频率小于前一次PID控制的第一工作频率时，制冷确定单元300还可将前一次PID控制的第一工作频率确定为本次PID控制的第一工作频率。When the number n corresponding to the PID control is not zero, that is, greater than zero, the refrigeration determination module 300 may directly determine the actual return operating frequency of the compressor as the first operating frequency. Or, when the number of times corresponding to the PID control is not zero, the running time of the compressor in the cooling mode is less than the set time, and the actual return working frequency of the compressor is less than the first working frequency of the previous PID control, the cooling determination unit 300 may also determine the first working frequency of the previous PID control as the first working frequency of the current PID control.

从而，制冷控制模块400可根据PID输出量对第一工作频率进行修正，得到压缩机的当前工作频率，并控制压缩机根据当前工作频率进行运行。并且，本次PID控制后，可将n+1。Therefore, the refrigeration control module 400 can correct the first operating frequency according to the PID output, obtain the current operating frequency of the compressor, and control the compressor to operate according to the current operating frequency. And, after this PID control, n+1 can be set.
