[0036] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0037] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0038] The main solution of this invention is to obtain the operating mode of the air conditioner; when the operating mode is dehumidification mode, control the indoor fan of the air conditioner to run at a target speed and adjust the operating frequency of the air conditioner compressor according to the first target indoor heat exchanger temperature, so that the air outlet temperature of the air conditioner is greater than the first target temperature and the humidity of the indoor environment is reduced.

[0039] In current technology, when indoor humidity is too high, dehumidification is generally achieved through cooling. However, the outlet air temperature is usually low during dehumidification, resulting in poor user comfort.

[0040] The present invention provides the above-mentioned solution, which aims to ensure dehumidification effect while avoiding excessively low outlet air temperature, thereby improving user comfort in dehumidification mode.

[0041] This invention provides an air conditioner. The air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a portable air conditioner, a window air conditioner, and / or a ceiling-mounted air conditioner, etc.

[0042] In this embodiment, refer to Figure 1 The air conditioner includes an indoor fan 1, a compressor 2, and a control device. Both the indoor fan 1 and the compressor 2 are connected to the control device.

[0043] Specifically, the air conditioner includes a casing, an indoor fan 1, and an indoor heat exchanger. The casing has an air outlet, and the casing has an air duct that communicates with the air outlet. The indoor fan 1 and the indoor heat exchanger are both located in the air duct. Driven by the indoor fan 1, indoor air enters the air duct and undergoes heat exchange through the indoor heat exchanger. The heat-exchanged air is then sent into the indoor environment from the air outlet.

[0044] Furthermore, the air conditioner also includes a refrigerant circulation system, which comprises the compressor 2, the first heat exchanger, the throttling device, and the second heat exchanger connected in sequence. The heat exchanger located indoors is defined as the indoor heat exchanger, and the heat exchanger located outdoors is defined as the outdoor heat exchanger. During cooling operation, the indoor heat exchanger is in an evaporating state to absorb heat from the indoor air.

[0045] Furthermore, the air conditioner may also include a humidity sensor 3 for detecting indoor humidity. The humidity sensor 3 is connected to a control device, which can be used to acquire the humidity data detected by the humidity sensor 3.

[0046] In this embodiment of the invention, reference is made to Figure 1The control device of the air conditioner includes: a processor 1001 (e.g., CPU), a memory 1002, etc. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk storage device. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0047] Those skilled in the art will understand that Figure 1 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0048] like Figure 1 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 1 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0049] This invention also provides a control method for an air conditioner, which is used to control the air conditioner described above.

[0050] Reference Figure 2 This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the control method for the air conditioner includes:

[0051] Step S10: Obtain the operating mode of the air conditioner;

[0052] Specifically, the operating modes of an air conditioner can be categorized based on the different target states that the air conditioner aims to achieve when regulating indoor air. In this embodiment, the operating modes include a dehumidification mode aimed at lowering indoor air temperature. In other embodiments, the operating modes may include a cooling mode aimed at lowering indoor air temperature, a heating mode aimed at raising indoor air temperature, a humidification mode aimed at increasing indoor air humidity, and other modes.

[0053] Step S20: When the operating mode is dehumidification mode, control the indoor fan of the air conditioner to run at the target speed and adjust the operating frequency of the air conditioner compressor according to the first target indoor heat exchanger temperature, so that the air outlet temperature of the air conditioner is greater than the first target temperature and the humidity of the indoor environment is reduced.

[0054] In dehumidification mode, the air conditioner operates in cooling mode, and the indoor heat exchanger absorbs heat in an evaporative state. After the indoor air passes through the indoor heat exchanger, the moisture in the air condenses on the heat exchanger, reducing the moisture in the air and thus lowering the humidity of the indoor air environment.

[0055] The target speed here can be a pre-set fixed speed, or a speed determined within a preset speed range based on the actual operating conditions of the air conditioner.

[0056] The first target indoor heat exchanger temperature is specifically the target temperature that the indoor heat exchanger needs to achieve in dehumidification mode. This first target indoor heat exchanger temperature can be a pre-set fixed parameter or a parameter determined based on the actual operating status of the air conditioner (e.g., based on the indoor fan speed and / or the current indoor ambient temperature). Specifically, the compressor frequency adjustment parameters (such as the frequency adjustment direction (e.g., increasing or decreasing frequency), frequency adjustment amplitude, or frequency adjustment rate) can be determined based on the temperature difference between the current temperature of the indoor heat exchanger and the first target indoor heat exchanger temperature. The compressor frequency is then controlled according to the determined frequency adjustment parameters to ensure that the indoor heat exchanger reaches the first target indoor heat exchanger temperature within a certain time frame.

[0057] The first target temperature is specifically the air outlet temperature value that makes the user feel comfortable and not cold. The first target temperature can be a preset fixed temperature value, a parameter determined based on the actual operating conditions of the air conditioner, or a temperature determined based on user-input settings. For example, the first target temperature can be determined based on the outdoor ambient temperature or the indoor ambient temperature when dehumidification mode is activated. In this embodiment, the range of the first target temperature is [18℃, 23℃], for example, 20℃.

[0058] This invention proposes a control method for an air conditioner. In the dehumidification mode of the air conditioner, the indoor fan operates at a target speed, and the compressor frequency is adjusted based on a first target indoor heat exchanger temperature. This allows the indoor ambient temperature to decrease while the air conditioner's outlet temperature reaches or exceeds the first target temperature, ensuring dehumidification while avoiding excessively low outlet temperatures and improving user comfort in dehumidification mode.

[0059] Specifically, in this embodiment, the indoor fan has a first speed setting, a second speed setting, and a third speed setting, where the first speed setting is lower than the second speed setting, and the second speed setting is lower than the third speed setting. Specifically, the first, second, and third speed settings are respectively the low, medium, and high speed settings of the indoor fan. For example, if the maximum operating speed of the indoor fan is defined as N, then the first speed setting is 1%N to 30%N, the second speed setting is 31%N to 70%N, and the third speed setting is 71%N to 100%N. Based on this, before the step of controlling the indoor fan of the air conditioner to operate at the target speed, the method further includes: when the operating mode is the dehumidification mode, determining the second speed setting as the target speed. In dehumidification mode, when the indoor fan speed is too low, the dehumidification effect is good but the outlet air temperature is too low; when the indoor fan speed is too high, the outlet air temperature is high but the dehumidification effect is poor. The indoor fan is running at medium speed, which helps to ensure good dehumidification while maintaining a higher outlet air temperature, thus achieving dehumidification while ensuring the comfort of indoor users.

[0060] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, before the step of modulating the compressor operating frequency of the air conditioner according to the first target indoor heat exchanger temperature, the method further includes:

[0061] Step S01: Determine the first target indoor heat exchanger temperature based on the target rotation speed and the first target temperature.

[0062] Different target rotational speeds and different first target temperatures correspond to different first target indoor heat exchanger temperatures. Specifically, the first target indoor heat exchanger temperature increases with the increase of the first target temperature, and the first target indoor heat exchanger temperature increases with the increase of the target rotational speed.

[0063] The correspondence between the target rotational speed, the first target temperature, and the first target indoor heat exchanger temperature can be preset. This correspondence can be a mapping relationship, a calculation relationship, etc. Based on this correspondence, the first target indoor heat exchanger temperature corresponding to the current target rotational speed and the first target temperature can be determined. For example, if the correspondence is a preset formula, the first target indoor heat exchanger temperature can be calculated by substituting the target rotational speed and the first target temperature into the preset formula.

[0064] In addition, more than one correspondence between target rotation speed and first target indoor heat exchanger temperature can be preset, and different correspondences can be associated with different first target temperatures. Based on this, the correspondence associated with the current target temperature can be used as the target correspondence, and the first target indoor heat exchanger temperature corresponding to the current target rotation speed can be determined based on the target correspondence.

[0065] Specifically, in this embodiment, the process of determining the first target indoor heat exchanger temperature is as follows: a reference coil temperature is determined based on the first target temperature, and a temperature correction value is determined based on the target rotation speed; the reference coil temperature is corrected based on the temperature correction value to obtain the first target indoor heat exchanger temperature.

[0066] Different target temperatures correspond to different reference coil temperatures, and different target rotational speeds correspond to different temperature correction values. The higher the target temperature, the higher the reference coil temperature; the higher the target rotational speed, the higher the temperature correction value.

[0067] In this embodiment, the reference coil temperature corresponding to the first target temperature is defined as T2, and the temperature correction value is k. Then, the first target temperature and the first target indoor heat exchanger temperature corresponding to the target rotation speed can be determined by the relationship in the table below:

[0068]

[0069]

[0070] Among them, k1 <k2<k3<k4。

[0071] Based on this, when the target rotational speed is 45%, the first target indoor heat exchanger temperature is T2; when the target rotational speed is 65%, the first target indoor heat exchanger temperature is T2+k3.

[0072] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, after step S10, it further includes: when the operating mode is a gentle temperature mode, obtaining the duration of the gentle temperature mode; if the duration is greater than or equal to a set duration, then when the current first humidity of the indoor environment is greater than or equal to a first set humidity, controlling the air conditioner to start the dehumidification mode; wherein, in the gentle temperature mode, the air conditioner operates in cooling mode and the air outlet temperature of the air conditioner is greater than a second target temperature, and the second target temperature is greater than or equal to the first target temperature. Specifically, the air conditioner can be controlled to operate in gentle temperature mode when a user input command is received or when the air conditioner reaches a set state. Here, the duration starts timing when the gentle temperature mode is started. A duration greater than or equal to a set duration indicates that the air conditioner is in gentle temperature mode for a long time, and the indoor user is in a relatively comfortable state. At this time, the indoor humidity is monitored, and when the humidity is detected to be too high, the dehumidification mode is entered, which helps to avoid excessively high indoor humidity. During the dehumidification process, the fan and compressor work together to reduce indoor humidity without the air outlet temperature being too low, further improving the comfort of the indoor user.

[0073] Furthermore, in this embodiment, after the step of obtaining the duration of the gentle temperature mode, the method further includes: if the duration is less than the set duration, adjusting the operating frequency of the compressor according to the second target indoor heat exchanger temperature so that the air outlet temperature of the air conditioner is greater than the second target temperature, wherein the second target indoor heat exchanger temperature is greater than the first target indoor heat exchanger temperature, and the second target temperature is greater than the first target temperature.

[0074] The second target indoor heat exchanger temperature is specifically the target temperature that the indoor heat exchanger needs to achieve in dehumidification mode. This second target indoor heat exchanger temperature can be a pre-set fixed parameter or a parameter determined based on the actual operating status of the air conditioner (e.g., based on the indoor fan speed and / or the current indoor ambient temperature). Specifically, the compressor frequency adjustment parameters (such as the frequency adjustment direction (e.g., increasing or decreasing frequency), frequency adjustment amplitude, or frequency adjustment rate) can be determined based on the temperature difference between the current temperature of the indoor heat exchanger and the second target indoor heat exchanger temperature. The compressor frequency is then controlled according to the determined frequency adjustment parameters to ensure that the indoor heat exchanger reaches the second target indoor heat exchanger temperature within a certain time frame.

[0075] For example, in the gentle temperature mode, the second target indoor heat exchanger temperature is 20 degrees Celsius, and in the dehumidification mode, the first target indoor heat exchanger temperature is 15 degrees Celsius.

[0076] In the gentle temperature mode, the air conditioner uses a higher target temperature of the indoor heat exchanger to regulate the compressor frequency, which helps ensure a higher outlet air temperature during cooling operation to guarantee user comfort. When the air conditioner switches from gentle temperature mode to dehumidification mode, it lowers the target temperature of the indoor heat exchanger to ensure that the outlet air temperature is not too low while achieving optimal dehumidification effect.

[0077] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 3 After step S20, the following steps are also included:

[0078] Step S30: Obtain the current second humidity of the indoor environment or the running time of the dehumidification mode;

[0079] Step S40: When the second humidity is less than or equal to the second set humidity, or when the running time is greater than or equal to the preset time, control the air conditioner to start the gentle temperature mode;

[0080] Step S50: In the gentle temperature mode, the air conditioner is controlled to operate in cooling mode and the operating frequency of the compressor is adjusted according to the second target indoor heat exchanger temperature so that the air outlet temperature of the air conditioner is greater than the second target temperature; wherein, the second target indoor heat exchanger temperature is greater than the first target indoor heat exchanger temperature, and the second target temperature is greater than the first target temperature.

[0081] The second setting of humidity and preset duration can be a fixed parameter that can be preset, or it can be a parameter determined based on the indoor humidity when entering dehumidification mode.

[0082] In dehumidification mode, if the detected humidity is low or the dehumidification mode runs for a long enough time, it indicates that the indoor humidity can be reduced to a level that meets the user's comfort level. At this time, the air conditioner starts the gentle temperature mode and cools with a higher air outlet temperature, thereby ensuring that the air outlet temperature of the air conditioner will not be too low during the cooling process, and ensuring that both temperature and humidity meet the user's comfort level.

[0083] Furthermore, based on any of the above embodiments, after the step of obtaining the operating mode of the air conditioner, the method further includes: when the operating mode is the dehumidification mode, during the step of controlling the indoor fan of the air conditioner to run at a target speed and adjusting the compressor operating frequency of the air conditioner according to the first target indoor heat exchanger temperature, controlling the air guide plate of the air outlet of the air conditioner to run at a first air guide angle so that the air conditioner delivers air towards the upper space of the indoor environment.

[0084] In this embodiment, the air conditioner is a wall-mounted air conditioner. In other embodiments, the air conditioner may be other types of air conditioners.

[0085] In the dehumidification mode here, the air guide plate operates at the first air guiding angle to direct the air from the air conditioner to the upper part of the space, thereby achieving dehumidification while preventing the air from blowing directly onto the user, thus further preventing cold air from blowing onto the user and further improving user comfort.

[0086] Furthermore, when the air conditioner exits the dehumidification mode and enters the gentle temperature mode, the air guide plate can be controlled to switch from the first air guide angle to the second air guide angle. At the second air guide angle, the air conditioner directs air towards the upper part of the indoor environment. Based on this, it is beneficial to ensure the heat exchange efficiency of the air conditioner in the gentle temperature mode. Moreover, since the outlet air temperature is too high in the gentle temperature mode, the indoor temperature can be cooled down quickly while the outlet air temperature can meet the user's comfort needs.

[0087] Furthermore, this invention also proposes a computer-readable storage medium storing a control program for an air conditioner. When the control program is executed by a processor, it implements the relevant steps of any of the above-described air conditioner control methods.
