- Embodiment 1 is a diagrammatic representation of Embodiment 1:
- FIG1 is a flow chart of an embodiment of a compressor frequency control method according to an exemplary embodiment.
- the compressor involved is a variable frequency compressor, that is, the operating frequency of the compressor can be changed.
- the compressor frequency control method comprises the following steps:
- Step 101 reducing the operating frequency of the compressor to a first frequency value based on the torque compensation frequency, where the first frequency value is greater than or equal to the torque compensation frequency.
- the torque compensation frequency is the compressor frequency that triggers the compressor current compensation mechanism.
- the torque compensation frequency is a relatively low compressor frequency.
- the vibration of the compressor body will increase due to the low frequency operation of the compressor.
- the current compensation mechanism triggered at this time dynamically determines the compensation current value based on the acquired compressor vibration data, and then compensates this compensation current value to the operating current of the compressor, so as to achieve the purpose of suppressing the vibration of the compressor.
- the torque compensation frequency of the compressor is between 45 Hz and 55 Hz.
- the torque compensation frequency is 50Hz
- the compressor operating frequency is below 50Hz
- the compensation current value is calculated according to the collected vibration data, and then the calculated compensation current value is compensated to the current operating current of the compressor.
- step 101 Before executing step 101, it is possible to determine whether the compressor is in a high-pressure operating state by acquiring the operating parameters of the compressor. If so, a process of adaptively reducing the compressor frequency based on the torque compensation frequency is triggered.
- the operating parameter value of the compressor may be acquired in real time, and the operating parameter value may be compared with a first preset parameter value. When the operating parameter value exceeds the first preset parameter value, step 101 is triggered.
- the operating parameter value of the compressor can represent the magnitude of the pressure intensity inside the compressor, and the first preset parameter value is a preset trigger threshold value of the adaptive frequency reduction.
- the operating parameter value has exceeded the first preset parameter value, it means that the pressure intensity inside the compressor is relatively high. At this time, it is not suitable to respond to the frequency adjustment command sent by the upper computer for rapid frequency adjustment, nor is it suitable to continue operating at the current operating frequency. It is necessary to reduce the pressure intensity inside the compressor in time to avoid long-term operation under high pressure intensity.
- the operating parameter value of the compressor may include one or more of the operating current of the compressor, the body temperature of the compressor, and the body pressure of the compressor.
- the operating current, body temperature and body pressure of the compressor can effectively reflect the intensity of the internal pressure of the compressor.
- the operating current of the compressor belongs to the electrical signal of the compressor and can be directly collected.
- the compressor body temperature can be collected by setting a temperature sensor at a certain position on the compressor body, such as an NTC (Negative Temperature Coefficient) thermistor sensor.
- a temperature sensor such as an NTC (Negative Temperature Coefficient) thermistor sensor.
- the compressor body pressure can be acquired by setting a pressure sensor at a certain position of the compressor body.
- the operating current of the compressor is detected in real time.
- the operating current exceeds a preset current threshold, it indicates that the internal pressure of the compressor is very high due to long-term operation, thus triggering the process of executing step 101.
- the operating parameter value of the compressor does not exceed the first preset parameter value, it means that the pressure intensity inside the compressor is moderate. Even if the frequency adjustment is performed quickly in response to the frequency adjustment command issued by the upper computer, it will not cause compressor protection problems. Therefore, in this case, the operating frequency of the compressor can be adjusted to the target frequency indicated by the frequency adjustment command based on the received frequency adjustment command.
- the system may continue to operate at the current operating frequency.
- the target frequency indicated by the frequency adjustment command is an operating frequency dynamically determined by the device according to actual needs, indicating the compressor frequency required for the operation of the device. It is an instruction issued by the software program of the device host computer and has no direct relationship with the aforementioned torque compensation frequency and the first frequency value.
- the required operating frequency of the compressor is calculated according to the target temperature, and a frequency adjustment command is generated based on the calculated operating frequency.
- a target operating frequency is calculated based on the target temperature and the current operating frequency of the compressor, and the frequency adjustment command is generated using the target operating frequency.
- the frequency adjustment command generated according to temperature is only an exemplary description.
- the frequency can also be adjusted according to the condensing temperature of the heat pump circulation system.
- There are many ways to trigger the generation of frequency adjustment commands which does not constitute a limitation to the present application scheme.
- the frequency reduction amplitude of the compressor can be limited by setting a preset threshold value to ensure the effect of reducing the internal pressure of the compressor. In other words, the difference between the first frequency value and the torque compensation frequency is less than the preset threshold value.
- the first frequency value must be less than or equal to 60 Hz, that is, the compressor frequency of 100 Hz must be reduced to below 60 Hz and above 50 Hz.
- Step 102 Maintain the operating frequency of the compressor at a first frequency value for a preset time period.
- the preset duration is the time for maintaining operation after the first stage frequency reduction in step 101 is executed.
- the compressor is allowed to continue running at the torque compensation frequency for a preset time period.
- the compressor is allowed to continue running at the first frequency value for a preset time period.
- Step 103 reducing the operating frequency of the compressor to a second frequency value.
- the second frequency value is a preset lower frequency that is smaller than the torque compensation frequency.
- the frequency reduction stage of the above step 101 can be called the first frequency reduction stage.
- the operating frequency of the compressor drops to above the torque compensation frequency and maintains operation for a period of time. This can provide a buffer drop time for the pressure inside the compressor, and the operating current of the compressor will gradually decrease as the pressure decreases;
- the frequency reduction stage of step 103 can be called the second frequency reduction stage.
- the operating frequency of the compressor is further reduced to a lower frequency, so that the pressure inside the compressor can be further reduced.
- the operating parameter value of the compressor can be obtained again and the obtained operating parameter value can be compared with the second preset parameter value.
- the obtained operating parameter value is lower than the second preset parameter value, it means that the pressure inside the compressor has indeed dropped. At this time, whether it is a rapid frequency reduction or a rapid frequency increase, it will not cause the compressor protection problem. Therefore, according to the received frequency adjustment command, the operating frequency of the compressor can be adjusted to the frequency adjustment command indication.
- the target frequency is shown.
- the operating frequency of the compressor can be maintained at the second frequency value until the operating parameter value of the compressor is lower than the second preset parameter value, and then the operating frequency of the compressor is adjusted to the target frequency indicated by the frequency adjustment command according to the received frequency adjustment command.
- the operating parameter value of the compressor may include one or more of the operating current of the compressor, the body temperature of the compressor, and the body pressure of the compressor.
- the operating current, body temperature and body pressure of the compressor can effectively reflect the magnitude of the internal pressure intensity of the compressor.
- the second preset parameter value is a pre-set operating parameter threshold for characterizing a relatively low internal pressure of the compressor. Since the first preset parameter value is a pre-set trigger threshold for adaptive frequency reduction, the compressor is under the condition of the first preset parameter value, which indicates that the internal pressure intensity of the compressor is relatively high. Therefore, the second preset parameter value is smaller than the first preset parameter value.
- the target frequency indicated by the frequency adjustment command is an operating frequency dynamically determined by the device according to actual needs, and has no direct relationship with the aforementioned torque compensation frequency, first frequency value, and second frequency value. Generally speaking, the target frequency indicated by the frequency adjustment command is greater than the aforementioned second frequency value.
- the compressor frequency control process shown in Figure 1 above is completed, by reducing the operating frequency of the compressor to a first frequency value greater than or equal to the torque compensation frequency, and maintaining the operating frequency of the compressor at the first frequency value for a preset period of time, so that the pressure of the compressor gradually decreases during the preset period of time, but the compressor current compensation mechanism is not triggered, and then the operating frequency of the compressor is reduced to a second frequency value, so that the operating frequency of the compressor is reduced to a lower frequency, and the compressor pressure is also completely reduced, thereby reducing the compressor protection problem caused by the pressure not being reduced due to the frequency reduction speed being too fast.
- Embodiment 2 is a diagrammatic representation of Embodiment 1:
- the overall implementation flow chart of the compressor frequency control as shown in FIG2 includes the following steps:
- Step 1 Detect the operating parameter values of the compressor in real time.
- the operating parameter value of the compressor can represent the magnitude of the pressure intensity inside the compressor.
- the operating parameter value of the compressor may include one or more of the operating current of the compressor, the body temperature of the compressor, and the body pressure of the compressor.
- the operating current, body temperature and body pressure of the compressor can effectively reflect the intensity of the internal pressure of the compressor.
- the operating current of the compressor belongs to the electrical signal of the compressor and can be directly collected.
- the compressor body temperature can be collected by setting a temperature sensor (such as an NTC thermistor sensor) at a certain position of the compressor body.
- a temperature sensor such as an NTC thermistor sensor
- the compressor body pressure can be acquired by setting a pressure sensor at a certain position of the compressor body.
- Step 2 Determine whether the detected operating parameter value is greater than the first preset parameter value. If so, execute step 3; otherwise, execute step 7.
- the first preset parameter value is a preset trigger threshold for adaptive frequency reduction. If the operating parameter value has reached the first preset parameter value, it means that the pressure intensity inside the compressor is relatively large, and the process of adaptively reducing the compressor frequency based on the torque compensation frequency is triggered; if the operating parameter value of the compressor does not exceed the first preset parameter value, it means that the pressure intensity inside the compressor is moderate.
- Step 3 reducing the operating frequency of the compressor to a first frequency value based on the torque compensation frequency, and maintaining the operating frequency of the compressor at the first frequency value for a preset period of time.
- the torque compensation frequency is the compressor frequency that triggers the compressor current compensation mechanism. It is a relatively low compressor frequency.
- the vibration of the compressor body will increase due to the low frequency operation of the compressor.
- the current compensation mechanism triggered dynamically determines the compensation current value based on the acquired compressor vibration data, and then compensates this compensation current value to the operating current of the compressor, so as to achieve the purpose of suppressing the vibration of the compressor.
- the operating frequency of the compressor may be reduced to a first frequency value that is greater than or equal to the torque compensation frequency to avoid triggering the current compensation mechanism and thereby causing an instantaneous sudden change in the compressor current.
- step 3 during the preset running time period, since the operating frequency of the compressor is always above the torque compensation frequency, the current compensation mechanism will not be triggered, thus not causing the compressor current to surge. The sudden change phenomenon will not cause the compressor protection problem.
- Step 4 Reduce the operating frequency of the compressor to a second frequency value.
- the second frequency value is a preset lower frequency that is smaller than the torque compensation frequency.
- Step 5 Continue to detect the operating parameter values of the compressor in real time.
- Step 6 Determine whether the detected operating parameter value is less than the second preset parameter value, if so, execute step 7, otherwise, execute step 8.
- the second preset parameter value is a pre-set operating parameter threshold for characterizing that the internal pressure of the compressor is relatively low. Since the first preset parameter value is a pre-set trigger threshold for adaptive frequency reduction, the compressor is under the condition of the first preset parameter value, which indicates that the internal pressure intensity of the compressor is relatively high. Therefore, the second preset parameter value is smaller than the first preset parameter value.
- the operating parameter value By comparing the detected operating parameter value with the second preset parameter value, if the operating parameter value is less than the second preset parameter value, it means that the pressure inside the compressor has indeed dropped. At this time, whether it is a rapid frequency reduction or a rapid frequency increase, it will not cause compressor protection problems; and if the operating parameter value is not less than the second preset parameter value, it means that the pressure inside the compressor has not yet been completely reduced.
- Step 7 According to the received frequency adjustment command, the operating frequency of the compressor is adjusted to the target frequency indicated by the frequency adjustment command.
- the target frequency indicated by the frequency adjustment command is an operating frequency dynamically determined by the device according to actual needs, and has no direct relationship with the aforementioned torque compensation frequency.
- Step 8 Keep the operating frequency of the compressor at the second frequency value, and return to step 5.
- the operating parameter value is not lower than the second preset parameter value, it means that the pressure inside the compressor has not been completely reduced. It is not suitable to quickly reduce or increase the frequency at this time, so the operating frequency of the compressor can be maintained at the second frequency value until the operating parameter value of the compressor is lower than the second preset parameter value, and then the operating frequency of the compressor is adjusted to the target frequency indicated by the frequency adjustment command according to the received frequency adjustment command.
- the present application also provides an embodiment of a compressor frequency control device.
- FIG3 is a schematic structural diagram of a compressor frequency control device according to an exemplary embodiment, wherein the device is used to execute the compressor frequency control method provided in any of the above embodiments.
- the compressor frequency control device includes:
- a first frequency reduction module 310 is used to reduce the operating frequency of the compressor to a first frequency value based on the torque compensation frequency, and maintain the operating frequency of the compressor at the first frequency value for a preset period of time; the first frequency value is greater than or equal to the torque compensation frequency, and the torque compensation frequency is the compressor frequency that triggers the compressor current compensation mechanism;

如前所述,随着压缩机的长时间运行,会出现压缩机系统压力大、温度高的问题,当上位机检测到压缩机温度太高时,触发压缩机的降频逻辑,由于在本申请之前的现有技术中提供的降频逻辑是按照某一常量进行逐步降频,为了保证降频效率,降频速度比较快,压缩机频率很快便会降至较低频率,而此时压缩机压力还未降下去,在这种低频、大压力情况下很容易引起压缩机保护问题。
经实验研究发现,在快速降频过程中,当压缩机频率降至力矩补偿频率以下时,为了抑制压缩机振动,会触发压缩机的电流补偿机制,此时由于压缩机压力大,电流也比较高,因此在进行电流补偿之后,致使压缩机电流瞬间突变,从而引起压缩机保护。
基于此,为了减少压缩机在高压力下运行引起的压缩机保护问题,本申请提出一种压缩机频率控制方法,以实现压缩机的自适应降频目的。
也即,通过将压缩机的运行频率降低至大于等于力矩补偿频率的第一频率值,并将压缩机的运行频率保持在第一频率值持续运行预设时长,以使压缩机的压力在该预设时长的时间段里逐渐下降,但又不会触发压缩机电流补偿机制,然后再将压缩机的运行频率降至第二频率值,使得压缩机的运行频率降至较低频率,由于此时压缩机的压力和电流已经降下去,即使此时触发压缩机的电流补偿机制,也不会引起电流瞬间突变的问题,因此也就不会引起压缩机保护的问题。
在本申请实施例中,压缩机频率控制方案除了可以适用于热泵式干衣机之外,还可以适用于热泵空调机组。
下面以具体的实施例对本申请的技术方案以及本申请的技术方案如何解决前述技术问题进行详细说明。所列举的若干具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。以下将结合附图,对本申请的实施例进行详细描述。
实施例一:
图1为根据一示例性实施例示出的一种压缩机频率控制方法的实施例流程示意图,在本申请实施例中,所涉及的压缩机为变频压缩机,即压缩机的运行频率可以变化。
如图1所示,所述压缩机频率控制方法包括如下步骤:
步骤101:基于力矩补偿频率将压缩机的运行频率降低至第一频率值,第一频率值大于等于力矩补偿频率。
其中,力矩补偿频率是触发压缩机电流补偿机制的压缩机频率。
值得注意的是,该力矩补偿频率是一个比较低的压缩机频率,在压缩机的运行频率小于力矩补偿频率时,由于压缩机是以低频运行,压缩机机身振动会加重,此时触发的电流补偿机制是根据获取的压缩机振动量数据动态确定补偿电流值,然后将这个补偿电流值补偿到压缩机的运行电流上,以此来达到抑制压缩机振动的目的。
在一种实现方式中,压缩机的力矩补偿频率位于45Hz-55Hz之间。
举例来说,假设力矩补偿频率为50Hz,当压缩机的运行频率处于50Hz以下
时,通过采集压缩机振动量数据,并根据采集的振动量数据计算补偿电流值,然后将计算的补偿电流值补偿到压缩机的当前运行电流上。
在执行步骤101之前,可以通过获取压缩机的运行参数判断压缩机是否处于高压力运行状态下,如果是,则触发基于力矩补偿频率自适应降低压缩机频率的流程。
在一种可能实现方式中,可以实时获取压缩机的运行参数值,将运行参数值与第一预设参数值进行比较,在运行参数值超过第一预设参数值的情况下,触发执行步骤101。
其中,压缩机的运行参数值可以表征压缩机内部的压力强度的大小,第一预设参数值是预先设定的自适应降频的触发阈值。
如果运行参数值已经超过第一预设参数值,说明压缩机内部的压力强度比较大,此时不适宜响应上位机下发的频率调节命令进行快速调频,也不适宜按照当前运行频率继续运行,需要及时将压缩机内部的压力强度降下来,避免长时间在高压力强度下运行。
在一可选实施例中,压缩机的运行参数值可以包括压缩机的运行电流、压缩机的机身温度、压缩机的机身压力中的一种或多种。
其中,压缩机的运行电流、机身温度及机身压力均能有效反映压缩机内部压力强度的大小。
也就是说,运行电流或者机身温度或者机身压力越高,说明压缩机内部压力强度越高。
在具体实施时,压缩机的运行电流属于压缩机的电信号,可以直接采集到。
压缩机的机身温度可以通过在压缩机机身的某个位置设置温度传感器采集机身温度,例如NTC(Negative Temperature Coefficient,负温度系数)热敏电阻传感器。
压缩机的机身压力可以通过在压缩机机身的某个位置设置压力传感器采集压力强度。
在一具体实施方式中,通过实时检测压缩机的运行电流,当出现运行电流超过预设电流阈值时,说明此时因为长时间运行,压缩机内部压力强度已经很高,于是触发执行步骤101的过程。
需要说明的是,如果压缩机的运行参数值未超过第一预设参数值,说明压缩机内部的压力强度适中,即使响应上位机下发的频率调节命令进行快速调频也不至于引起压缩机保护问题,因此,此种情况下,可以根据接收到频率调节命令,将压缩机的运行频率调节至频率调节命令指示的目标频率。
进一步地,如果没有频率调节命令下发,也可以按照当前运行频率继续运行。
在本申请实施例中,频率调节命令指示的目标频率是设备根据实际需求动态确定的一个运行频率,指示了设备运行需要的压缩机频率,是由设备上位机的软件程序下发的指令,与前述的力矩补偿频率和第一频率值之间没有直接关系。
以热泵式干衣机为例,在烘干衣物过程中,假设检测到烘干筒中的空气温度超出限值,可能对衣物造成损伤,于是根据目标温度计算出压缩机需要的运行频率,并基于计算出的运行频率生成频率调节命令。
又假设,检测到烘干筒中的空气温度低于目标温度,可能延长衣物烘干时间,于是根据目标温度和压缩机的当前运行频率计算出一个目标运行频率,从而利用该目标运行频率生成频率调节命令。
可以理解的是,上述给出的根据温度生成频率调节命令仅为一种示例性说明,除了根据温度进行频率调节之外,还可以根据热泵循环系统的冷凝温度调节频率,触发生成频率调节命令的方式多种多样,其并不形成对本申请方案的限制。
针对步骤101中基于力矩补偿频率将压缩机的运行频率降低至第一频率值的过程,在一种可选的实施方式中,可以通过设定预设阈值来限定压缩机的降频幅度,以确保压缩机内部压力的下降效果。也就是说,第一频率值与力矩补偿频率之间的差值要小于预设阈值。
举例说明,假设压缩机的运行频率是100Hz,力矩补偿频率是50Hz,预设阈值为10Hz,那么第一频率值要小于等于60Hz,也就是说,要将100Hz的压缩机频率降至60Hz以下,50Hz以上。
基于上述两种实施方式可知,只要将压缩机的运行频率降到力矩补偿频率以上的频率值,便不会触发电流补偿机制,这样就不会引起压缩机电流瞬间突变的现象,从而也就不会导致压缩机保护问题。
步骤102:将压缩机的运行频率保持在第一频率值持续运行预设时长。
其中,该预设时长是在执行完步骤101的第一阶段降频之后维持运行的时间。
也就是说,如果第一频率值等于力矩补偿频率的频率值,那么就是让压缩机按照力矩补偿频率持续运行预设时长。
如果是第一频率值大于力矩补偿频率的频率值,那么就是让压缩机按照第一频率值持续运行预设时长。
值得注意的是,在该预设时长的运行时间段里,由于压缩机的运行频率始终在力矩补偿频率以上,因此不会触发电流补偿机制,这样就不会引起压缩机电流瞬间突变的现象,从而也就不会导致压缩机保护问题。
与此同时,在这段运行时间段里,由于压缩机的运行频率降低了,因此压缩机内部的压力强度也会缓慢降下来,随之压缩机的电流也会缓慢降下来。
步骤103:将压缩机的运行频率降至第二频率值。
其中,第二频率值是一个比力矩补偿频率更小的预设设定的较低频率,通过将压缩机的运行频率降到该第二频率值,可以彻底将压缩机内部的压力强度降下来。
可以理解的是,上述步骤101的降频阶段可以称为第一降频阶段,在第一降频阶段,压缩机的运行频率下降到力矩补偿频率以上,并维持运行一段时间,这样可以给压缩机内部的压力提供一个缓冲下降时间,压缩机的运行电流也会随着压力的下降而逐渐降下来;步骤103的降频阶段可以称为第二降频阶段,在第二降频阶段,将压缩机的运行频率继续再降到一个更低的频率,这样可以让压缩机内部的压力进一步降下来。
值得注意的是,在将压缩机的运行频率降至第二频率值时,由于压缩机内部的压力在第一降频阶段已经缓慢降下来了,运行电流也随之降低,因此即使此时因为运行频率在力矩补偿频率以下,触发了电流补偿机制,也不会引起压缩机电流瞬间突变的现象,从而也就不会导致压缩机保护问题。
需要说明的是,为了验证压缩机内部压力是否真实降下去,在将压缩机的运行频率降至第二频率值之后,可以通过再获取压缩机的运行参数值,并将获取的运行参数值与第二预设参数值进行比较。
如果获取的运行参数值低于第二预设参数值,表示压缩机内部的压力确实降下去了,此时无论是快速降频还是快速升频,均不会引起压缩机保护问题,因此可以根据接收到频率调节命令,将压缩机的运行频率调节至所述频率调节命令指
示的目标频率。
而如果获取的运行参数值不低于第二预设参数值,表示压缩机内部的压力还未彻底降下去,此时还不适宜快速降频或快速升频,因此可以将压缩机的运行频率保持在第二频率值运行,直到压缩机的运行参数值低于第二预设参数值,再开始根据接收到频率调节命令,将压缩机的运行频率调节至所述频率调节命令指示的目标频率。
如前所述,压缩机的运行参数值可以包括压缩机的运行电流、压缩机的机身温度、压缩机的机身压力中的一种或多种。
其中,压缩机的运行电流、机身温度及机身压力均能有效反映压缩机内部压力强度的大小,运行电流或者机身温度或者机身压力越高,说明压缩机内部压力强度越高。
值得注意的是,第二预设参数值是预先设定的用于表征压缩机内部压力比较低的运行参数阈值,由于第一预设参数值是预先设定的自适应降频的触发阈值,压缩机在第一预设参数值的条件下,表示压缩机内部压力强度比较大,因此第二预设参数值要小于第一预设参数值。
如前所述,频率调节命令指示的目标频率是设备根据实际需求动态确定的一个运行频率,与前述的力矩补偿频率、第一频率值、第二频率值之间没有直接关系。通常来说,频率调节命令指示的目标频率大于前述的第二频率值。
至此,完成上述图1所示的压缩机频率控制流程,通过将压缩机的运行频率降低至大于等于力矩补偿频率的第一频率值,并将压缩机的运行频率保持在第一频率值持续运行预设时长,以使压缩机的压力在该预设时长的时间段里逐渐下降,但又不会触发压缩机电流补偿机制,然后再将压缩机的运行频率降至第二频率值,使得压缩机的运行频率降至较低频率,同时压缩机压力也彻底降下来了,从而减少因为降频速度太快而压力未降下去引起的压缩机保护问题。
实施例二:
结合上述图1所示实施例的基础上,下面对压缩机频率控制的整体实现方案进行解释说明。
如图2所示的压缩机频率控制的整体实现流程图,包括如下步骤:
步骤1:实时检测压缩机的运行参数值。
其中,压缩机的运行参数值可以表征压缩机内部的压力强度的大小。
可选的,压缩机的运行参数值可以包括压缩机的运行电流、压缩机的机身温度、压缩机的机身压力中的一种或多种。
其中,压缩机的运行电流、机身温度及机身压力均能有效反映压缩机内部压力强度的大小。
也就是说,运行电流或者机身温度或者机身压力越高,说明压缩机内部压力强度越高。
在具体实施时,压缩机的运行电流属于压缩机的电信号,可以直接采集到。
压缩机的机身温度可以通过在压缩机机身的某个位置设置温度传感器(例如NTC热敏电阻传感器)采集机身温度。
压缩机的机身压力可以通过在压缩机机身的某个位置设置压力传感器采集压力强度。
步骤2:判断检测到的运行参数值是否大于第一预设参数值,若是,则执行步骤3,否则,执行步骤7。
其中,第一预设参数值是预先设定的自适应降频的触发阈值。如果运行参数值已经达到第一预设参数值,说明压缩机内部的压力强度比较大,则触发基于力矩补偿频率自适应降低压缩机频率的流程;如果压缩机的运行参数值未超过第一预设参数值,说明压缩机内部的压力强度适中。
步骤3:基于力矩补偿频率将压缩机的运行频率降低至第一频率值,并将压缩机的运行频率保持在第一频率值持续运行预设时长。
其中,力矩补偿频率是触发压缩机电流补偿机制的压缩机频率,是一个比较低的压缩机频率,在压缩机的运行频率小于力矩补偿频率时,由于压缩机是以低频运行,压缩机机身振动会加重,此时触发的电流补偿机制是根据获取的压缩机振动量数据动态确定补偿电流值,然后将这个补偿电流值补偿到压缩机的运行电流上,以此来达到抑制压缩机振动的目的。
可选的,可以将压缩机的运行频率降至大于等于力矩补偿频率的第一频率值,以避免触发电流补偿机制,进而引起压缩机电流瞬间突变的现象。
在步骤3中,在预设时长的运行时间段里,由于压缩机的运行频率始终在力矩补偿频率以上,因此不会触发电流补偿机制,这样就不会引起压缩机电流瞬间
突变的现象,从而也就不会导致压缩机保护问题。
与此同时,在这段运行时间段里,由于压缩机的运行频率降低了,因此压缩机内部的压力强度也会缓慢降下来,随之压缩机的电流也会缓慢降下来。
步骤4:将压缩机的运行频率降至第二频率值。
其中,第二频率值是一个比力矩补偿频率更小的预设设定的较低频率,通过将压缩机的运行频率降到该第二频率值,可以彻底将压缩机内部的压力强度降下来。
值得注意的是,在将压缩机的运行频率降至第二频率值时,由于压缩机内部的压力在第一降频阶段已经缓慢降下来了,运行电流也随之降低,因此即使此时因为运行频率在力矩补偿频率以下,触发了电流补偿机制,也不会引起压缩机电流瞬间突变的现象,从而也就不会导致压缩机保护问题。
步骤5:继续实时检测压缩机的运行参数值。
关于运行参数值的相关解释说明,请参考上述步骤1的相关阐述。
步骤6:判断检测到的运行参数值是否小于第二预设参数值,若是,则执行步骤7,否则,执行步骤8。
其中,第二预设参数值是预先设定的用于表征压缩机内部压力比较低的运行参数阈值,由于第一预设参数值是预先设定的自适应降频的触发阈值,压缩机在第一预设参数值的条件下,表示压缩机内部压力强度比较大,因此第二预设参数值要小于第一预设参数值。
通过将检测到的运行参数值与第二预设参数值进行比较,如果运行参数值小于第二预设参数值,表示压缩机内部的压力确实降下去了,此时无论是快速降频还是快速升频,均不会引起压缩机保护问题;而如果运行参数值不小于第二预设参数值,表示压缩机内部的压力还未彻底降下去。
步骤7:根据接收到频率调节命令,将压缩机的运行频率调节至频率调节命令指示的目标频率。
其中,频率调节命令指示的目标频率是设备根据实际需求动态确定的一个运行频率,与前述的力矩补偿频率之间没有直接关系。
步骤8:将压缩机的运行频率保持在第二频率值运行,并返回执行步骤5。
如果运行参数值不低于第二预设参数值,表示压缩机内部的压力还未彻底降
下去,此时还不适宜快速降频或快速升频,因此可以将压缩机的运行频率保持在第二频率值运行,直到压缩机的运行参数值低于第二预设参数值,再开始根据接收到频率调节命令,将压缩机的运行频率调节至所述频率调节命令指示的目标频率。
至此,完成上述图2所示的压缩机频率控制的整体实现流程。
