Air conditioners are already common electrical appliances in daily life. They can adjust the indoor temperature, and can also quickly reduce the indoor humidity, making the humid air in the room refreshing. However, during the dehumidification process of the air conditioner, there may be relatively large fluctuations in the indoor temperature. In the embodiment of the present invention, the operating frequency of the compressor of the air conditioner can be adjusted with a set frequency range according to the temperature of the air conditioner's active area. In this way, the operating frequency of the compressor can be slowly adjusted, so as to achieve the dehumidification effect while maintaining a stable temperature in the operating area, effectively preventing large-scale temperature fluctuations, and further improving the comfort and experience of air conditioner users.

Fig. 1 is a flowchart showing a method for controlling dehumidification of an air conditioner according to an exemplary embodiment. As shown in Figure 1, the process of air conditioning dehumidification control includes:

Step 101: Obtain the current ambient temperature of the air-conditioning area in the dehumidification working mode.

In the embodiment of the present invention, the air conditioner can have multiple working modes, including: cooling mode, heating mode, and dehumidification mode. The air conditioner can enter the dehumidification mode according to the humidity of the air conditioning area; or, according to the user's instruction, enter the dehumidification mode, that is, the air conditioner can be in the dehumidification working mode.

Therefore, when the air conditioner is in the dehumidification working mode, the temperature sensor may have detected the current ambient temperature in the air-conditioning area, so that the current ambient temperature can be obtained according to the detected current ambient temperature. Alternatively, the current ambient temperature T _ai is obtained directly through a temperature sensor.

Step 102: When the current ambient temperature difference between the current ambient temperature and the set ambient temperature is greater than the upper limit of the set ambient temperature difference range, increase the current operating frequency of the compressor of the air conditioner with the first set frequency range , until the current ambient temperature difference is within the set ambient temperature difference range or the current operating frequency reaches the first preset frequency threshold.

Step 103: When the current ambient temperature difference is less than the lower limit of the set ambient temperature difference range, reduce the current operating frequency of the compressor of the air conditioner with the second set frequency range until the current ambient temperature difference is within the set ambient temperature difference within the range or the current operating frequency reaches the second preset frequency threshold.

In the embodiment of the present invention, a target ambient temperature may be preconfigured, that is, the set ambient temperature T _set . Therefore, the current ambient temperature difference ΔT _h between the current ambient temperature and the set ambient temperature =T _ai −T _set . In addition, you can also configure a set ambient temperature difference range, which can be (lower limit ambient temperature difference value, upper limit ambient temperature difference value), for example: (0,3), (-1,2), (-2,3), (- 0.5, 2.5), etc., preferably, the lower limit ambient temperature difference value is not less than -5, and the upper limit ambient temperature difference value is not greater than 5 values, and the specific values will not be listed one by one.

After the current ambient temperature difference △T _h is determined, the current ambient temperature difference △T _h can be compared with the set ambient temperature difference range, and if the current ambient temperature difference △T _h is greater than the upper limit of the ambient temperature difference, the execution Step 102, increasing the current working frequency of the compressor of the air conditioner with the first set frequency range until the current ambient temperature difference is within the set ambient temperature difference range or the current working frequency reaches the first preset frequency threshold.

For example: the first preset frequency threshold is 80HZ, and the current operating frequency of the compressor of the air conditioner is 60HZ. Since the current ambient temperature difference △T _h is greater than the upper limit of the ambient temperature difference, the current operating frequency of the compressor needs to be increased. At this time, You can first set the frequency range, for example: 1HZ/min, to increase the current operating frequency of the compressor, and then, after one minute or the set time, you can judge whether the increased current operating frequency is greater than or equal to the first preset Set the frequency threshold, if not, continue to sample the current ambient temperature _Tai , and then continue to judge whether the updated △T _h is within the set ambient temperature difference range? If not, and △T _h is greater than the upper limit of ambient temperature difference, continue to increase the current operating frequency of the compressor with the first set frequency range, and also judge the current operating frequency after the increase after one minute or the set time. Whether the working frequency is greater than or equal to the first preset frequency threshold, and if so, determine the current working frequency as the first preset frequency threshold.

When comparing the current ambient temperature difference △T _h with the set ambient temperature difference range, it is possible that the current ambient temperature difference △T _h is smaller than the lower limit ambient temperature difference. At this time, step 103 can be executed, that is, the second set frequency The current operating frequency of the compressor of the air conditioner is reduced until the current ambient temperature difference is within the set ambient temperature difference range or the current operating frequency reaches the second preset frequency threshold.

For example: the second preset frequency threshold is 10HZ, and the current operating frequency of the compressor of the air conditioner is 60HZ. Since the current ambient temperature difference △T _h is less than the lower limit ambient temperature difference, the current operating frequency of the compressor needs to be reduced. At this time, you can The second set frequency range is for example: 2HZ/min, to reduce the current operating frequency of the compressor, and then, after one minute or the set time, it can be judged whether the reduced current operating frequency is less than or equal to the second preset frequency threshold , if not, continue to sample the current ambient temperature _Tai , and then continue to judge whether the updated △T _h is within the set ambient temperature difference range? If not, and △T _h is less than the lower limit ambient temperature difference, then continue to reduce the current operating frequency of the compressor with the second set frequency range, and also judge the reduced current operating frequency after one minute or after the set time Whether it is less than or equal to the second preset frequency threshold, if yes, determine the current working frequency as the second preset frequency threshold.

In the embodiment of the present invention, the first set frequency range and the second set frequency range are relatively small, so that the current operating frequency of the compressor can be adjusted slowly, thereby avoiding wide-range temperature fluctuations during the dehumidification process. Of course, the first set frequency range and the second set frequency range may be the same or different. Preferably, both the first set frequency range and the second set frequency range are less than 5 Hz/min.

Of course, when the current ambient temperature difference ΔT _h is within the set ambient temperature difference range, the current operating frequency of the compressor may not be adjusted, that is, the current operating frequency may be maintained.

In another embodiment of the present invention, when the current ambient temperature difference △T _h is not only smaller than the lower limit ambient temperature difference value of the set ambient temperature range, but also less than the set value, it is necessary to stop the compressor of the air conditioner to ensure the dehumidification control of the air conditioner. warming effect. Here, the setting value needs to be less than the lower limit ambient temperature difference. For example, if the set value is -5, the lower limit ambient temperature difference value is -1, or if the set value is -3, the lower limit ambient temperature difference value is 0. That is, in this embodiment, when the current ambient temperature difference ΔT _h is less than the lower limit ambient temperature difference value of the set ambient temperature difference range, and is greater than or equal to the set value, the current operating frequency of the compressor of the air conditioner can be reduced by the second set frequency range until the current ambient temperature difference is within the set ambient temperature difference range or the current operating frequency reaches the second preset frequency threshold. And when the current ambient temperature difference ΔT _h is less than the set value, the compressor of the air conditioner is directly stopped.

Since the air conditioner is in the dehumidification working mode, not only the compressor of the air conditioner but also the fan of the air conditioner need to be operated. Of course, while adjusting the operating frequency of the compressor of the air conditioner, the fan of the air conditioner can be operated in the existing way, for example: the fan runs at a low wind speed gear for the first set minute, and then stops the fan for the second setting Minutes wait. Preferably, the embodiment of the present invention can adjust the current operating frequency of the compressor of the air conditioner according to the ambient temperature difference, and at the same time, according to the current coil temperature difference between the collected current coil temperature and the set coil temperature , to adjust the working wind speed of the fan of the air conditioner, which may specifically include: obtaining the current coil temperature of the fan of the air conditioner; when the current coil temperature difference between the current coil temperature and the set coil temperature is greater than the set coil temperature difference When the coil temperature difference is the upper limit of the range, reduce the current working wind speed of the fan of the air conditioner with the first set wind speed range until the current coil temperature difference is within the set environmental coil range or the current working wind speed reaches the first preset wind speed Threshold; when the current coil temperature difference is less than the lower limit coil temperature difference of the set coil temperature range, the current working wind speed of the fan of the air conditioner will be increased by the second set wind speed until the current coil temperature difference is within the set value. The temperature difference range of the fixed coil tube or the current working wind speed reaches the second preset wind speed threshold.

Generally, the dew point temperature can be determined according to the preset ambient temperature and the humidity of the active area, and thus the set coil temperature can be obtained.

In Table 1, the ambient temperature T _set can be set according to the humidity to determine the corresponding dew point temperature T _dp , and thus the set coil temperature T _ct =T _dp −3 can be determined.

Table 1

After the set coil temperature has been determined, the current coil temperature _Tc of the fan coil of the air conditioner can also be obtained through the temperature sensor near the fan coil, so as to obtain the current coil temperature between the current coil temperature and the set coil temperature. Tube temperature difference ΔT _c =T _c -T _ct . Similarly, a set coil temperature difference range can be pre-configured, which can be (lower limit coil temperature difference value, upper limit coil temperature difference value), for example: (0, 2), (-1, 1), (-0.5, 1.5) Etc., preferably, the lower limit coil temperature difference is not less than -5, and the upper limit coil temperature difference is not greater than 5. The specific values will not be listed one by one.

After the current coil temperature difference △T _c is determined, the current coil temperature difference △T _c can be compared with the set coil temperature difference range, if the current coil temperature difference △T _c is greater than the upper limit coil temperature difference , the current working wind speed of the fan of the air conditioner can be reduced by the first set wind speed range until the current coil temperature difference is within the set coil temperature difference range or the current working wind speed reaches the first preset wind speed threshold.

For example: the first preset wind speed threshold is 200r/min, and the current working wind speed of the fan of the air conditioner is 600r/min. Since the current coil temperature difference ΔT _c is greater than the upper limit coil temperature difference, the current working wind speed of the fan needs to be reduced. At this time, you can first set the wind speed range, for example: 30r/2min, to reduce the current working wind speed of the fan, and then, after two minutes or after the set time, you can judge whether the reduced current working wind speed is less than or equal to the first preset. Set the wind speed threshold, if not, continue to sample the current coil temperature T _c , and then continue to judge whether the updated △T _c is within the set coil temperature difference range? If not, and △T _c is greater than the upper limit coil temperature difference, continue to reduce the current working wind speed of the fan with the first set wind speed range, and also judge the reduced current working wind speed after two minutes or after the set time Whether it is less than or equal to the first preset wind speed threshold, if yes, determine the current working wind speed as the first preset wind speed threshold.

When comparing the current coil temperature difference △T _c with the set coil temperature difference range, it is possible that the current coil temperature difference △T _c is smaller than the lower limit coil temperature difference value, at this time, the second set wind speed range can be increased The current working wind speed of the fan of the air conditioner until the current coil temperature difference is within the set coil temperature difference range or the current working wind speed reaches the second preset wind speed threshold.

For example: the second preset wind speed threshold is 900r/min, and the current working wind speed of the fan of the air conditioner is 600r/min. Since the current coil temperature difference △T _c is less than the lower limit coil temperature difference, the current working wind speed of the fan needs to be increased , at this time, you can secondly set the wind speed range, for example: 40r/2min, to increase the current working wind speed of the fan, and then, after two minutes or after the set time, you can judge whether the current working wind speed after the increase is greater than or equal to If there is no second preset wind speed threshold, continue to sample the current coil temperature T _c , and then continue to judge whether the updated ΔT _c is within the set coil temperature difference range? If not, and △T _c is less than the lower limit coil temperature difference value, continue to increase the current working wind speed of the fan with the second set wind speed range, and also judge the current working wind speed after the increase after two minutes or the set time. Whether the working wind speed is greater than or equal to the second preset wind speed threshold, if yes, the current working wind speed is determined as the second preset wind speed threshold.

In the embodiment of the present invention, the first set wind speed range and the second set wind speed range are relatively small, so that the current working wind speed of the fan can be slowly adjusted, thereby avoiding wide-range temperature fluctuations during the dehumidification process. Certainly, the first set wind speed range and the second set wind speed range may be the same or different. Preferably, both the first set wind speed range and the second set wind speed range are less than 50HZ/2min.

Of course, when the current coil temperature difference ΔT _c is within the set coil temperature range, the current working wind speed of the fan may not be adjusted, that is, the current working wind speed may be maintained.

When the air conditioner enters the dehumidification working mode, the fan may not be turned on. Therefore, before reducing the current working wind speed of the fan of the air conditioner by the first set wind speed range, it also includes: starting the fan to run according to the set wind speed value, and reaching the preset value. time. For example: after ten minutes of running the fan at a wind speed of 800r/min, the current working wind speed of the fan of the air conditioner is reduced by the first set wind speed. The normal dehumidification and temperature control function of the air conditioner.

It can be seen that in the embodiment of the present invention, according to the ambient temperature difference between the current ambient temperature and the set ambient temperature of the air conditioner operating area in the dehumidification working mode, the operating frequency of the compressor of the air conditioner is adjusted with the set frequency range, In this way, the compressor is not only turned on and off, but also the operating frequency of the compressor can be adjusted slowly, so as to achieve the dehumidification effect while keeping the temperature in the working area stable, effectively preventing large-scale temperature fluctuations, and improving the safety of air conditioner users. comfort and experience. Preferably, according to the current coil temperature difference between the collected current coil temperature and the set coil temperature, the working wind speed of the fan of the air conditioner can be adjusted with the set wind speed range. Similarly, the fan is not only turned on And shut down, the wind speed of the fan can be slowly adjusted, while protecting the equipment, it further reduces the chance of large-scale temperature fluctuations during the dehumidification process of the air conditioner, and further improves the comfort and experience of the air conditioner users.

In the following, the operation flow of the scheme is integrated into a specific embodiment to illustrate the method provided by the embodiment of the present disclosure.

Embodiment 1. In this embodiment, the air conditioner in the dehumidification working mode can adjust the operating frequency of the compressor of the air conditioner with a set frequency range according to the ambient temperature difference between the current ambient temperature and the set ambient temperature. Wherein, the set ambient temperature range may be (0,3), and the set value is -3. The first preset frequency range and the second preset frequency range are equal to 2HZ/min, and the first preset frequency threshold is 100HZ, and the second preset frequency threshold is 5HZ. The sampling time is 5 minutes, that is, the set time interval is 5 minutes.

Fig. 2 is a flow chart of an air conditioner dehumidification control method according to an exemplary embodiment 1. As shown in Fig. 2 , the process of air conditioner dehumidification control includes:

Step 201: Obtain the current ambient temperature T _ai of the air-conditioning area.

Step 202: Determine whether ΔT _h > 3 holds true? If yes, go to step 203; otherwise, go to step 206.

Is the current ambient temperature difference ΔT _h between the current ambient temperature T _ai and the _set ambient temperature T set greater than the upper limit of the ambient temperature difference 3 within the set ambient temperature range? If yes, go to step 203; otherwise, go to step 206.

Step 203: Increase the current operating frequency of the compressor by 2HZ/min.

The current operating frequency of the compressor of the air conditioner is increased by the first set frequency range.

Step 204: Judging whether the current operating frequency ≥ 100 Hz raised after five minutes is established? If yes, execute step 205; otherwise, return to step 201.

Step 205, determine that the current operating frequency of the compressor of the air conditioner is 100HZ.

Step 206: Determine whether △T _h <0 holds true? If yes, execute step 207, otherwise, execute step 212

Is the current ambient temperature difference △T _h less than the lower limit ambient temperature difference value 0 of the set ambient temperature range? If yes, go to step 207; otherwise, go to step 212.

Step 210: Determine that the current operating frequency of the compressor of the air conditioner is 5HZ.

Step 211: Stop the operation of the compressor of the air conditioner.

When △T _h is not only less than the lower limit of the ambient temperature difference range, but also less than the set value, the compressor of the air conditioner needs to be stopped to ensure the dehumidification and temperature control effect of the air conditioner.

Step 212: Keep the current operating frequency of the compressor of the air conditioner unchanged.

ΔT _h is in (0,3), that is, when the current ambient temperature difference ΔT _h is within the set ambient temperature difference range, the current operating frequency of the compressor may not be adjusted, that is, the current operating frequency may be maintained.
