技术领域technical field
本申请涉及空调器技术领域，尤其涉及一种空调压缩机的频率控制方法、装置及空调器。The present application relates to the technical field of air conditioners, in particular to a frequency control method and device for an air conditioner compressor and an air conditioner.
背景技术Background technique
在炎热的夏季，变频空调器能将室内环境温度长时间维持在一个恒定的温度，与定频空调器相比，变频空调器能有效避免室内温度的波动，以及减少压缩机的启停次数，降低了压缩机产生了的噪音。In the hot summer, the inverter air conditioner can maintain the indoor ambient temperature at a constant temperature for a long time. Compared with the fixed frequency air conditioner, the inverter air conditioner can effectively avoid the fluctuation of the indoor temperature and reduce the number of start and stop of the compressor. The noise generated by the compressor is reduced.
现有变频空调器的变频控制方法是根据压缩机出气口的冷媒温度进行反馈调节，在压缩机出气口的冷媒温度过低时，控制压缩机频率升高，以提升冷媒温度，在压缩机出气口的冷媒温度过高时，控制压缩机频率降低，以降低冷媒温度，当室外温度较高造成室外机换热困难时，室外机的冷凝器换热效率较低，空调器制冷效果下降，压缩机需升高频率以加快换热，但是压缩机频率升高后冷媒温度相应地也会升高，此时变频控制方法的反馈调节会控制降低压缩机频率，导致压缩机频率反复升降，从而产生较大的噪音，并在压缩机的运行频率不稳定时，空调器的出风温度一致性差，严重影响到用户体验。The frequency conversion control method of the existing inverter air conditioner is to perform feedback adjustment according to the temperature of the refrigerant at the air outlet of the compressor. When the temperature of the refrigerant at the air outlet of the compressor is too low, the frequency of the compressor is controlled to increase to increase the temperature of the refrigerant. When the temperature of the refrigerant at the air port is too high, reduce the frequency of the compressor to reduce the temperature of the refrigerant. When the outdoor temperature is high and the heat exchange of the outdoor unit is difficult, the heat exchange efficiency of the condenser of the outdoor unit is low, and the cooling effect of the air conditioner decreases. The machine needs to increase the frequency to speed up the heat exchange, but the temperature of the refrigerant will rise correspondingly after the frequency of the compressor is increased. At this time, the feedback adjustment of the frequency conversion control method will control the frequency of the compressor to be reduced, causing the frequency of the compressor to rise and fall repeatedly, resulting in Loud noise, and when the operating frequency of the compressor is unstable, the temperature consistency of the air outlet of the air conditioner is poor, which seriously affects the user experience.

下面结合图1至图5描述本申请提供的一种空调压缩机的频率控制方法、装置及空调器。A frequency control method and device for an air conditioner compressor and an air conditioner provided in the present application will be described below with reference to FIGS. 1 to 5 .
如图1所示，本实施例提供一种空调压缩机的频率控制方法，包括：S110，获取空调器在制冷模式下室外机所处的环境温度，以及空调器的压 缩机的排气温度。As shown in FIG. 1 , this embodiment provides a method for controlling the frequency of an air conditioner compressor, including: S110, obtaining the ambient temperature of the outdoor unit of the air conditioner in cooling mode and the exhaust temperature of the compressor of the air conditioner.
S120，在环境温度大于预设温度的情况下，根据排气温度所处的温度变化区段，确定压缩机所处的运行模式；运行模式包括升频模式、第一恒频模式、降频模式及第二恒频模式当中的任一种，温度变化区段包括多个，多个温度变化区段当中的四者分别与升频模式、第一恒频模式、降频模式及第二恒频模式一一对应。S120, when the ambient temperature is greater than the preset temperature, determine the operating mode of the compressor according to the temperature change zone where the exhaust gas temperature is located; the operating mode includes an up-frequency mode, a first constant frequency mode, and a down-frequency mode and any one of the second constant frequency mode, the temperature change section includes a plurality, and four of the plurality of temperature change sections are respectively associated with the up-frequency mode, the first constant frequency mode, the down-frequency mode and the second constant frequency mode Patterns correspond one-to-one.
S130，以依次排列的升频模式、第一恒频模式、降频模式及第二恒频模式为一个循环周期，按照确定的运行模式在循环周期所处的位置，执行对压缩机的循环运行控制。S130, taking the up-frequency mode, the first constant frequency mode, the down-frequency mode, and the second constant frequency mode arranged in sequence as a cycle, and performing cyclic operation of the compressor according to the position of the determined operation mode in the cycle control.
具体地，本实施例在制冷模式下室外机所处的环境温度较高造成室外机换热困难的情况下，压缩机的排气温度升高，通过获取的压缩机的排气温度，根据排气温度所处的温度变化区段，控制压缩机以相应的运行模式运行，其中，第一恒频模式与第二恒频模式对应的温度变化区段不同，则在压缩机在升频模式和降频模式切换的过程中，压缩机的排气温度可在多个温度变化区段内以恒定的频率运行，避免压缩机出现频繁升降频的现象。Specifically, in this embodiment, in cooling mode, when the ambient temperature of the outdoor unit is high and heat exchange is difficult for the outdoor unit, the discharge temperature of the compressor rises. The temperature change zone where the gas temperature is located, and the compressor is controlled to run in the corresponding operation mode. Wherein, the temperature change zone corresponding to the first constant frequency mode and the second constant frequency mode are different, and the compressor is in the up-frequency mode and In the process of frequency reduction mode switching, the discharge temperature of the compressor can be operated at a constant frequency in multiple temperature ranges, avoiding the phenomenon of frequent frequency reduction of the compressor.
在此应指出的是，空调器的压缩机的常规控制方法是通过获取室内环境温度与设定温度的温差值，在温差值较大的情况下，控制压缩机的频率增大，在温差值较小的情况下，控制压缩机的频率降低或控制压缩机的频率保持不变。而在室外机所处的环境温度较高的情况下，室外机的换热效率较低，室内机的制冷效果较差，此时若盲目提升压缩机的频率，无法有效改善室内机的制冷效果，还会造成压缩机的排气温度过高，排气温度过高的情况下，压缩机为了保持安全运行状态，压缩机会进行降频操作，压缩机的频率会出现频繁升降的现象，因此，本实施例通过判断空调器室外机所处的环境温度与预设温度的大小关系，确定室外机是否存在换热困难的现象。It should be pointed out here that the conventional control method of the compressor of the air conditioner is to obtain the temperature difference between the indoor ambient temperature and the set temperature. When the temperature difference is large, the frequency of the compressor is controlled to increase. In smaller cases, the frequency of the control compressor is reduced or the frequency of the control compressor remains unchanged. However, when the ambient temperature of the outdoor unit is high, the heat exchange efficiency of the outdoor unit is low, and the cooling effect of the indoor unit is poor. At this time, if the frequency of the compressor is increased blindly, the cooling effect of the indoor unit cannot be effectively improved. , it will also cause the exhaust temperature of the compressor to be too high. When the exhaust temperature is too high, in order to maintain the safe operation state of the compressor, the compressor will perform frequency reduction operation, and the frequency of the compressor will rise and fall frequently. Therefore, In this embodiment, by judging the relationship between the ambient temperature of the outdoor unit of the air conditioner and the preset temperature, it is determined whether the outdoor unit is difficult to exchange heat.
优选地，如图2所示，本实施例所示的根据排气温度所处的温度变化区段，确定压缩机所处的运行模式，包括：Preferably, as shown in FIG. 2, the determination of the operating mode of the compressor according to the temperature change section of the exhaust gas temperature shown in this embodiment includes:

S230，在判定排气温度处于上升的变化趋势的情况下，若排气温度大于或等于第一温度，且小于第二温度，确定运行模式为第一恒频模式。S230. When it is determined that the exhaust gas temperature is on an upward trend, if the exhaust gas temperature is greater than or equal to the first temperature and less than the second temperature, determine that the operation mode is the first constant frequency mode.
S240，在判定排气温度处于上升的变化趋势的情况下，若排气温度大于或等于第二温度，且小于第三温度，确定运行模式为降频模式。S240, if it is determined that the exhaust gas temperature is on an upward trend, if the exhaust gas temperature is greater than or equal to the second temperature and less than the third temperature, determine that the operating mode is the down-frequency mode.

When it is determined that the exhaust gas temperature is on a downward trend, if the exhaust gas temperature is less than or equal to the fourth temperature and greater than the fifth temperature, determine that the operation mode is the second constant frequency mode.
S260，在判定排气温度处于下降的变化趋势的情况下，若排气温度小于或等于第五温度，确定运行模式为升频模式。S260, if it is determined that the exhaust gas temperature is in a downward trend, if the exhaust gas temperature is less than or equal to the fifth temperature, determine that the operation mode is the up-frequency mode.
其中，第五温度、第一温度、第四温度、第二温度及第三温度依次增大。Wherein, the fifth temperature, the first temperature, the fourth temperature, the second temperature and the third temperature increase sequentially.
具体地，本实施例所示的压缩机的排气温度上升至第一温度时，压缩机运行第一恒频模式，此时压缩机的频率保持不变，由于排气温度的变化滞后于压缩机频率的变化，因此，尽管此时压缩机的频率保持不变，但是排气温度还会继续上升；当排气温度上升至第二温度时，压缩机运行降频模式，此时压缩机的频率降低，相应地，排气温度也下降；当排气温度下降至第四温度时，压缩机运行第二恒频模式，此时压缩机的频率保持不变，同理，由于排气温度的变化滞后于压缩机频率的变化，此时排气温度还会继续下降；当排气温度下降至第五温度时，压缩机运行升频模式，并按照上述过程依次循环。Specifically, when the discharge temperature of the compressor shown in this embodiment rises to the first temperature, the compressor runs in the first constant frequency mode, and the frequency of the compressor remains unchanged at this time, because the change of the discharge temperature lags behind the compression Therefore, although the frequency of the compressor remains unchanged at this time, the discharge temperature will continue to rise; when the discharge temperature rises to the second temperature, the compressor operates in the frequency reduction mode, and the compressor’s The frequency decreases, and accordingly, the discharge temperature also decreases; when the discharge temperature drops to the fourth temperature, the compressor operates in the second constant frequency mode, and the frequency of the compressor remains unchanged at this time. The change lags behind the change of the compressor frequency, and the discharge temperature will continue to drop at this time; when the discharge temperature drops to the fifth temperature, the compressor operates in the frequency-up mode, and cycles in sequence according to the above process.
在此应指出的是，本实施例所示的获取排气温度在单位时间内的变化趋势，具体获取方法可以为，在一个连续的时间区间内，采集相邻两个时间点的排气温度，若前一个时间点的排气温度低于后一个时间点的排气温度，则可判定在该时间区间内，排气温度处于上升的变化趋势；若前一个时间点的排气温度高于后一个时间点的排气温度，则可判定在该时间区间内，排气温度处于下降的变化趋势。It should be pointed out here that the specific acquisition method for obtaining the change trend of the exhaust gas temperature per unit time shown in this embodiment can be to collect the exhaust gas temperature at two adjacent time points in a continuous time interval , if the exhaust gas temperature at the previous time point is lower than the exhaust gas temperature at the next time point, it can be determined that the exhaust gas temperature is on an upward trend within this time interval; if the exhaust gas temperature at the previous time point is higher than If the exhaust gas temperature at the later time point is determined, it can be determined that the exhaust gas temperature is in a downward trend within this time interval.
优选地，本实施例所示的第五温度与第一温度之间的温差值小于第一温度与第四温度之间的温差值；第四温度与第二温度之间的温差值小于第一温度与第四温度之间的温差值。Preferably, the temperature difference between the fifth temperature and the first temperature shown in this embodiment is smaller than the temperature difference between the first temperature and the fourth temperature; the temperature difference between the fourth temperature and the second temperature is smaller than the first temperature The temperature difference value between the temperature and the fourth temperature.
具体地，在排气温度低于第五温度时，压缩机运行升频模式，排气温度升高，由于第五温度与第一温度之间的温差值较小，因此，排气温度能 够快速上升至第一温度，使得压缩机快速进入第一恒频模式；相应地，当排气温度高于第二温度时，压缩机运行降频模式，排气温度下降，由于第四温度与第二温度之间的温差值较小，因此，排气温度能够快速下降至第四温度，使得压缩机快速进入第二恒频模式，以实现压缩机尽可能维持在第一恒频模式或第二恒频模式，避免压缩机频率的频繁升降。Specifically, when the exhaust gas temperature is lower than the fifth temperature, the compressor operates in the up-frequency mode, and the exhaust gas temperature rises. Since the temperature difference between the fifth temperature and the first temperature is small, the exhaust gas temperature can rapidly increase. Rise to the first temperature, so that the compressor quickly enters the first constant frequency mode; correspondingly, when the discharge temperature is higher than the second temperature, the compressor operates in the frequency reduction mode, and the discharge temperature drops, due to the fourth temperature and the second The temperature difference between the temperatures is small, so the discharge temperature can quickly drop to the fourth temperature, so that the compressor can quickly enter the second constant frequency mode, so as to maintain the compressor in the first constant frequency mode or the second constant frequency mode as much as possible. frequency mode to avoid frequent ups and downs of compressor frequency.
在此应指出的是，现有压缩机频率的控制对应一个升频模式、一个恒频模式及一个降频模式，由于只有一个恒频模式，则该恒频模式只对应一个温度区间，因此，无论是由升频模式切换至恒频模式，还是由降频模式切换至恒频模式，排气温度均需要满足上述温度区间，因此会出现压缩机频率频繁升降的现象，而本实施例中设有第一恒频模式与第二恒频模式，压缩机相对更容易保持当前频率运行，避免压缩机频率频繁升降。It should be pointed out here that the existing compressor frequency control corresponds to an up-frequency mode, a constant frequency mode and a down-frequency mode. Since there is only one constant frequency mode, the constant frequency mode only corresponds to one temperature range. Therefore, Regardless of switching from the up-frequency mode to the constant-frequency mode or from the down-frequency mode to the constant frequency mode, the exhaust gas temperature must meet the above temperature range, so there will be frequent fluctuations in the frequency of the compressor. With the first constant frequency mode and the second constant frequency mode, it is relatively easier for the compressor to maintain the current frequency operation and avoid frequent frequency fluctuations of the compressor.
优选地，如图3所示，本实施例所示的空调压缩机的频率控制方法还包括：S310，当排气温度上升的过程中，当排气温度大于或等于第二温度，且小于第六温度时，控制压缩机的频率以第一速率降低；S320，在排气温度上升的过程中，当排气温度大于或等于第六温度，且小于第三温度时，控制压缩机的频率以第二速率降低；第二温度、第六温度及第三温度依次增大，第一速率小于第二速率。Preferably, as shown in FIG. 3 , the frequency control method of the air conditioner compressor shown in this embodiment further includes: S310, when the exhaust gas temperature is rising, when the exhaust gas temperature is greater than or equal to the second temperature and less than the second temperature When the temperature is six, control the frequency of the compressor to decrease at the first rate; S320, during the process of rising the exhaust temperature, when the exhaust temperature is greater than or equal to the sixth temperature and less than the third temperature, control the frequency of the compressor to decrease at a rate of The second rate decreases; the second temperature, the sixth temperature and the third temperature increase sequentially, and the first rate is lower than the second rate.
具体地，在排气温度上升的过程中，若排气温度未上升到第六温度，则此时排气温度相对较低，压缩机以第一速率降低运行频率即可实现排气温度的下降；若排气温度已超过第六温度，则此时排气温度相对较高，压缩机需要快速降低运行频率，此时压缩机以第二速率降低运行频率，实现排气温度的快速下降。Specifically, in the process of increasing the exhaust gas temperature, if the exhaust gas temperature has not risen to the sixth temperature, the exhaust gas temperature is relatively low at this time, and the compressor can reduce the operating frequency at the first rate to realize the decrease of the exhaust gas temperature. ; If the exhaust temperature has exceeded the sixth temperature, the exhaust temperature is relatively high at this time, and the compressor needs to quickly reduce the operating frequency. At this time, the compressor reduces the operating frequency at the second rate to achieve a rapid drop in the exhaust temperature.
优选地，本实施例所示的空调压缩机的频率控制方法还包括：在判定排气温度处于上升的变化趋势的情况下，当排气温度大于或等于第三温度时，控制压缩机关闭。Preferably, the frequency control method of the air conditioner compressor shown in this embodiment further includes: when it is determined that the exhaust gas temperature is on an upward trend, when the exhaust gas temperature is greater than or equal to the third temperature, controlling the compressor to be turned off.
具体地，当排气温度大于或等于第三温度时，此时排气温度过高，为避免压缩机的损坏，需控制压缩机关闭。Specifically, when the discharge temperature is greater than or equal to the third temperature, the discharge temperature is too high at this time, and in order to avoid damage to the compressor, the compressor needs to be controlled to be turned off.

在一个实施例中，以空调器的压缩机刚启动为例，空调压缩机的频率 控制方法流程如下所述：压缩机在刚启动时，控制压缩机运行升频模式，压缩机频率逐渐升高，排气温度也逐渐升高，当排气温度升高至91℃时，控制压缩机运行第一恒频模式，此时排气温度还会继续上升，若排气温度上升至98℃，控制压缩机以第一速率降频，若排气温度上升至102℃，控制压缩机以第二速率降频，若排气温度上升至110℃，控制压缩机关闭；压缩机频率逐渐降低时，排气温度也逐渐下降，当排气温度下降至97℃时，控制压缩机运行第二恒频模式，此时排气温度还会继续下降，若排气温度下降至90℃，则控制压缩机运行升频模式，实现压缩机的循环运行控制。In one embodiment, taking the compressor of the air conditioner just starting up as an example, the flow of the frequency control method for the compressor of the air conditioner is as follows: when the compressor is just starting up, the compressor is controlled to run in the frequency-up mode, and the frequency of the compressor is gradually increased , the exhaust temperature also rises gradually. When the exhaust temperature rises to 91°C, control the compressor to run in the first constant frequency mode. At this time, the exhaust temperature will continue to rise. If the exhaust temperature rises to 98°C, control The frequency of the compressor is reduced at the first rate. If the exhaust temperature rises to 102°C, the compressor is controlled to decrease frequency at the second rate. If the exhaust temperature rises to 110°C, the compressor is controlled to be turned off; The air temperature also drops gradually. When the exhaust temperature drops to 97°C, the compressor is controlled to run in the second constant frequency mode. At this time, the exhaust temperature will continue to drop. If the exhaust temperature drops to 90°C, the compressor is controlled to run The up-frequency mode realizes the cycle operation control of the compressor.
