[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In this application, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] As the background technology shows, current air conditioners control dehumidification by setting the temperature, which is a single control method and cannot control humidity, resulting in a poor user experience.

[0040] Therefore, embodiments of the present invention provide an air conditioning control method, system, and related equipment. When the dehumidification mode of the air conditioner is activated, the indoor humidity, set humidity, and indoor temperature are acquired. The humidity difference between the set humidity and the indoor humidity is calculated, and a target operating frequency is determined based on the humidity difference and the indoor temperature. The air conditioner compressor is controlled to operate at the target operating frequency. The system supports user-defined set humidity, and the compressor's operating frequency is controlled based on the set humidity, indoor humidity, and indoor temperature to achieve dehumidification, thereby improving the user experience.

[0041] It should be noted that the air conditioning control method provided in the following embodiments of the present invention can be applied to variable frequency portable air conditioners, as well as other types of air conditioners with variable frequency functions.

[0042] See Figure 1 The flowchart illustrates an air conditioning control method according to an embodiment of the present invention, the air conditioning control method comprising:

[0043] Step S101: Activate the dehumidification mode of the air conditioner.

[0044] In the specific implementation of step S101, after receiving the dehumidification command for starting the dehumidification mode of the air conditioner, the dehumidification mode of the air conditioner is started.

[0045] In some embodiments, the dehumidification mode of the air conditioner is activated upon receiving a dehumidification command from the air conditioner remote control or upon receiving a dehumidification command from a mobile terminal connected to the air conditioner. In other words, the user can activate the dehumidification mode of the air conditioner via the air conditioner remote control or via a mobile terminal (such as a mobile phone) connected to the air conditioner.

[0046] Step S102: Obtain and display indoor humidity, and obtain set humidity and indoor temperature.

[0047] In the specific implementation of step S102, the current indoor humidity is collected by a humidity sensor and the collected indoor humidity is displayed. Specifically, the collected indoor humidity can be displayed on the display screen of the air conditioner or on the display screen of the air conditioner remote control (or mobile terminal).

[0048] It obtains the humidity setting set by the user via air conditioner remote control or mobile terminal, and collects the current indoor temperature through temperature sensor.

[0049] Step S103: Calculate the humidity difference between the set humidity and the indoor humidity.

[0050] In the specific implementation step S103, the humidity difference between the set humidity and the indoor humidity is calculated, and this humidity difference can be recorded as △H.

[0051] Step S104: Determine the target operating frequency based on the humidity difference and indoor temperature.

[0052] It should be noted that multiple preset temperature ranges are pre-defined, such as (-∞, 5℃], (5℃, 9℃], (9℃, 13℃], (13℃, 19℃], (19℃, 23℃], (23℃, 27℃], (27℃, 32℃], and (32℃, +∞). Among these preset temperature ranges, some can be considered high-temperature zones (with boundary temperatures exceeding a certain value), and some can be considered low-temperature zones. Because the load is higher in high-temperature zones, the air conditioner compressor needs to operate at a relatively high frequency when the indoor temperature is in the high-temperature zone; conversely, because the load is lower in low-temperature zones, the air conditioner compressor needs to operate at a relatively low frequency when the indoor temperature is in the low-temperature zone (achieving energy savings).

[0053] In some embodiments, after dividing multiple preset temperature ranges, a corresponding operating frequency range is set for each preset temperature range; that is, each preset temperature range is set with a corresponding operating frequency range.

[0054] In the specific implementation of step S104, from multiple preset temperature ranges, the preset temperature range that covers the indoor temperature is determined as the target temperature range; that is, the target temperature range is the preset temperature range that includes the indoor temperature.

[0055] In some embodiments, multiple humidity ranges are pre-defined, such as (50%, +∞), (30%, 50%), (10%, 30%), and (-∞, 10%). As can be seen from the above, each preset temperature range has a corresponding operating frequency range; for each preset temperature range, the corresponding operating frequency range is set with the operating frequencies for each preset humidity range; that is, for a given preset temperature range, the operating frequencies for each preset humidity range are pre-defined from the corresponding operating frequency range.

[0056] For example, refer to Table 1 below, where (9,13], (13,19], (13,19], (19,23], (23,27], and (32,+∞] are preset temperature ranges (in °C). As shown in Table 1, within the operating frequency range corresponding to the preset temperature range (9,13], the operating frequency corresponding to the preset humidity range (50%,+∞) is 36Hz, the operating frequencies corresponding to (30%,50%] and (10%,30%) are both 28Hz, and the operating frequency corresponding to the preset humidity range (-∞,10%) is 16Hz.

[0057] Table 1:

[0058] (9,13] (13,19] (13,19] (19,23] (23,27] (32,+∞] (50％,+∞] 36Hz 44Hz 50Hz 60Hz 64Hz 68Hz (30％,50％] 28Hz 32Hz 36Hz 40Hz 44Hz 50Hz (10％,30％] 28Hz 28Hz 28Hz 28Hz 28Hz 36Hz (-∞,10％] 16Hz 16Hz 16Hz 16Hz 16Hz 24Hz

[0059] It should be noted that the above examples of the operating frequencies corresponding to the preset temperature range and the preset humidity range are for illustrative purposes only; the operating frequencies corresponding to the preset humidity ranges can be set according to the actual situation, and no specific limitation is made here on the operating frequencies corresponding to the preset humidity ranges.

[0060] After determining the target temperature range, the target operating frequency is determined from the operating frequency range corresponding to the target temperature range based on the humidity difference. Specifically, from multiple preset humidity ranges, the preset humidity range covering the humidity difference is determined as the target humidity range; from the operating frequency range corresponding to the target temperature range, the operating frequency corresponding to the target humidity range is determined as the target operating frequency.

[0061] For example: Based on the information shown in Table 1 above, assuming the indoor temperature is 27℃, the target temperature range is determined to be (23, 27]. When the humidity difference ΔH is within the preset humidity range of (50%, +∞), (50%, +∞) is determined to be the target humidity range. As can be seen from Table 1 above, in the operating frequency range corresponding to (23, 27), the operating frequency corresponding to the preset humidity range of (50%, +∞) is 64Hz, so the target operating frequency is determined to be 64Hz.

[0062] Step S105: Control the air conditioner compressor to operate at the target operating frequency.

[0063] In the specific implementation of step S105, after determining the target operating frequency, the air conditioner compressor is controlled to operate at the target operating frequency.

[0064] For example, based on the information shown in Table 1 above, assuming the indoor temperature is 27℃, the target temperature range is determined to be (23, 27]. When the humidity difference ΔH is within the preset humidity range of (50%, +∞), the air conditioner compressor is controlled to operate at 64Hz (that is, the target operating frequency is 64Hz). When the humidity difference ΔH is within the preset humidity range of (30%, 50%), the air conditioner compressor is controlled to operate at 44Hz. When the humidity difference ΔH is within the preset humidity range of (10%, 30%), the air conditioner compressor is controlled to operate at 28Hz. When the humidity difference ΔH is within the preset humidity range of (-∞, 10%), the air conditioner compressor is controlled to operate at 16Hz.

[0065] As can be seen from the above examples, the larger the humidity difference, the greater the dehumidification demand, and the compressor needs to operate at a high frequency; the smaller the humidity difference, the smaller the dehumidification demand, and the compressor needs to operate at a low frequency.

[0066] It should be noted that, in order to address the dehumidification needs under low temperature and high humidity conditions, in some preferred embodiments, when the indoor temperature is below the temperature threshold, the four-way reversing valve of the air conditioner is controlled to switch, so that the condenser during cooling is converted into an evaporator.

[0067] For example, when the indoor temperature is below 9°C, the four-way reversing valve of the air conditioner is switched to heat and dehumidify, so that the condenser used for cooling becomes the evaporator.

[0068] It should be noted that during dehumidification, the moisture in the air condenses into water when it encounters the cold end and the temperature drops below the dew point. When the operating conditions are high (such as when the indoor temperature is above 9°C), the four-way reversing valve does not operate, and dehumidification is performed using the evaporator as the cold end and the condenser as the hot end. When the operating conditions drop to below 9°C, the four-way reversing valve operates, and the original evaporator becomes the condenser and the original condenser becomes the evaporator to perform dehumidification.

[0069] In this embodiment of the invention, when the dehumidification mode of the air conditioner is activated, the indoor humidity, the set humidity, and the indoor temperature are acquired. The humidity difference between the set humidity and the indoor humidity is calculated, and then the target operating frequency is determined based on the humidity difference and the indoor temperature. The air conditioner compressor is then controlled to operate at the target operating frequency. This solution allows users to set a set humidity, and controls the compressor's operating frequency based on the set humidity, indoor humidity, and indoor temperature to achieve dehumidification, thus improving the user experience.
