In the embodiment of the present disclosure, the air conditioner operating in the dehumidification mode may adjust the rotation speed of the indoor fan according to the outdoor temperature, and may perform proportional-Integral-derivative (PID) control according to a temperature difference between the current temperature value of the internal coil and a preset target temperature value of the internal coil, and determine the frequency of the compressor matched with the rotation speed of the indoor fan, so as to perform the dehumidification operation of the air conditioner according to the rotation speed of the indoor fan and the frequency of the compressor. Like this, outdoor temperature is higher, and indoor fan rotational speed is also higher, and for reaching coil pipe target temperature value in presetting, the compressor frequency is also big more, and at this moment, the air volume, the dehumidification is also big, has not only increaseed the dynamics of dehumidification, has also improved the efficiency of dehumidification.
Fig. 1 is a schematic flow chart of a humidity control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the process for the humidity control of the air conditioner includes:
step 101: and acquiring the current outdoor temperature value of the air conditioner running in the dehumidification mode.
In the embodiment of the present disclosure, the air conditioner may enter the dehumidification working mode according to the received user instruction information, or the air conditioner may enter the dehumidification working mode according to the collected current humidity value, for example, if the current humidity value Rhr is greater than or equal to 70%, and exceeds 10 minutes, the air conditioner may enter the dehumidification working mode.
The air conditioner in the dehumidification mode can acquire the outdoor temperature value of the environment where the outdoor unit of the air conditioner is located at regular time or in real time through the configured temperature detection device, and the outdoor temperature value acquired each time is the current outdoor temperature value.
Step 102: and determining the current indoor fan rotating speed corresponding to the current outdoor temperature value according to the corresponding relation between the indoor fan rotating speed and the outdoor temperature.
The upper limit of the frequency of the air-conditioning compressor is limited by the outer annular temperature, and in a refrigeration section of a dehumidification mode, the higher the outer annular temperature is, the larger the upper limit of the frequency of the compressor is, and the higher the upper limit of the frequency of the compressor is, a step-up function is formed. In addition, the dehumidification mode adopts PID control of the inner coil, so that the temperature of the inner coil is closely related to the frequency of the compressor and the rotating speed of the inner fan. When the outer loop temperature is higher, the rotating speed of the inner fan is also larger, so that the inner coil temperature reaches the preset target inner coil temperature by determining the proper compressor frequency.
Therefore, in some embodiments of the present disclosure, a corresponding relationship between the indoor fan rotation speed and the outdoor temperature may be preconfigured, and the corresponding relationship is matched with the preset target temperature value of the inner coil. The corresponding relation between the rotating speed of the indoor fan and the outdoor temperature can be configured and stored; or, the system is communicated with the cloud server to obtain the corresponding relation between the rotating speed of the indoor fan and the outdoor temperature. In the corresponding relation, the higher the outdoor temperature is, the higher the rotating speed of the indoor fan is. Therefore, the current outdoor temperature value is obtained, and the corresponding current indoor fan rotating speed can be determined according to the corresponding relation.
Table 1 shows a corresponding relationship between the rotation speed of the indoor fan and the outdoor temperature provided in the embodiment of the present disclosure. And the preset target temperature value TP-s of the inner coil matched with the corresponding relation is 10 ℃.
| Outdoor temperature Tao (. degree. C.) | Indoor fan speed (rpm) |
| Tao＞32 | 1000 |
| 22＜Tao≤32 | 900 |
| 16＜Tao≤22 | 800 |
| Tao≤16 | 700 |
TABLE 1
If the current outdoor temperature value is 20 ℃, the current indoor fan rotating speed can be determined to be 800rpm according to the corresponding relation shown in the table 1; and the current outdoor temperature value is 30 ℃, and the current indoor fan rotating speed can be determined to be 900rpm according to the corresponding relation shown in the table 1. That is, the higher the current outdoor temperature value is, the higher the current indoor fan rotating speed is.
In some embodiments, the cloud server stores a correspondence between the indoor fan rotation speed and the outdoor temperature, and thus, determining the current indoor fan rotation speed corresponding to the current outdoor temperature value according to the correspondence between the indoor fan rotation speed and the outdoor temperature includes: the method comprises the steps of sending a current outdoor temperature value and a preset target temperature value of an inner coil to a cloud server, and receiving a current indoor fan rotating speed which is sent by the cloud server and corresponds to the current outdoor temperature value, wherein the current indoor fan rotating speed is determined by the server according to a stored corresponding relation between the indoor fan rotating speed which is matched with the preset target temperature value of the inner coil and the outdoor temperature.

Step 103: and performing proportional-integral-derivative (PID) control on the inner coil according to the current indoor fan rotating speed and a preset target temperature value of the inner coil.
The air conditioner is still in the dehumidification mode operation, and according to interior coil pipe temperature, carries out PID control, realizes the dehumidification operation of air conditioner. In some embodiments, performing the internal coil PID control comprises: acquiring a current temperature value of the inner coil of the air conditioner, and acquiring a current temperature difference value between the current temperature value of the inner coil and a preset target temperature value of the inner coil; performing PID control according to the current temperature difference, and determining the current compressor frequency matched with the current indoor fan rotating speed; and performing dehumidification mode operation of the air conditioner according to the current indoor fan rotating speed and the current compressor frequency.
When PID control is carried out, the current compressor frequency is matched with the current indoor fan rotating speed, so that if the outdoor temperature is high, the indoor fan rotating speed is high, and the compressor frequency is high to reach the preset target indoor coil temperature, so that the indoor unit is high in ventilation quantity and high in dehumidification quantity. The maximum dehumidification capacity of the air conditioner is exerted by setting the rotating speed of the room fan corresponding to the outdoor temperature and adjusting the frequency of the compressor.
Therefore, in the embodiment, the air conditioner running in the dehumidification mode can adjust the rotating speed of the indoor fan according to the outdoor temperature, preset the target temperature value of the inner coil according to the rotating speed of the indoor fan, and perform proportional-integral-derivative (PID) control on the inner coil, so that the higher the outdoor temperature is, the higher the rotating speed of the indoor fan is, the higher the compressor frequency is to reach the preset target temperature value of the inner coil, at the moment, the ventilation volume and the dehumidification capacity are also large, the dehumidification strength is increased, and the dehumidification efficiency is also improved.
Of course, in order to further increase the air volume and improve the dehumidification strength and efficiency, in some embodiments, the rotation speed of the outdoor fan of the air conditioner may be adjusted to the maximum rotation speed.
