[0002] With the development of science and technology, the relevant technologies of air conditioning have made significant progress, and consumers have higher requirements for the user experience of air conditioning. In high temperature and high humidity environments, the air-conditioning systems in related technologies usually run the cooling and dehumidification functions at the same time. This mode has certain limitations in practical applications. First, the superimposed operation of the cooling and dehumidification functions will cause the system energy consumption to increase significantly, especially in environments with high humidity.

[0030] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0032] In related technologies, in high-temperature and high-humidity environments, the ambient temperature alone cannot accurately judge the human body's true feelings. In high-humidity environments, operating the cooling mode alone can easily cause the actual perceived temperature to be higher than the ambient temperature. In high-temperature and high-humidity environments, the air conditioner will produce more condensation water when running, which will put greater pressure on the drainage system. When high-humidity air passes through the evaporator, it is easy for condensation or even ice to form on the evaporator surface. The ice on the evaporator will hinder air flow, reduce the evaporation efficiency of the refrigerant, and thus reduce the cooling effect. High-humidity air contains more heat energy than dry air, and the air conditioner requires more energy to cool the moist air. This means that in high-humidity environments, the air conditioner needs to run longer or more frequently to achieve the same cooling effect, thereby increasing energy consumption and reducing energy efficiency.

[0033] The invention provides a method for controlling an air conditioner.

[0034] Figure 1 1 is a schematic diagram of an embodiment of the air conditioner control method provided by the present invention.

[0035] like Figure 1 As shown, according to one embodiment of the present invention, the air conditioner control method includes at least step S110, step S120, step S130 and step S140.

[0036] Step S110: After the air conditioner is started, the indoor ambient temperature and indoor relative humidity are detected.

[0037] Specifically, when the air conditioner is started, it begins to detect the indoor ambient temperature and indoor relative humidity. When using the air conditioner, the user can start the air conditioner and select the mode and set the corresponding temperature through the remote control or mobile phone APP. The air conditioner indoor unit receives the information, executes the startup function, and detects the indoor ambient temperature and indoor relative humidity.

[0038] Step S120: judging whether the indoor environment is in a high temperature and high humidity state according to the detected indoor environment temperature and indoor relative humidity.

[0039] Specifically, when the indoor ambient temperature is within the preset temperature range and the indoor relative humidity is within the preset humidity range, the indoor environment is judged to be in a high temperature and high humidity state. For example, when the indoor ambient temperature T is in the range of 26°C ≤ T ≤ 40°C, the indoor environment is in a high temperature state. When the indoor relative humidity RH is in the range of 60% ≤ RH ≤ 100%, the indoor environment is in a high humidity state. When the above two conditions are met at the same time, the indoor environment is in a high temperature and high humidity state.

[0040] In step S130, if it is determined that the indoor environment is in a high temperature and high humidity state, the current equivalent perceived temperature is determined based on the detected indoor environment temperature and indoor relative humidity.

[0041] Specifically, if the indoor environment is determined not to be in a high temperature and high humidity state, the system operates in a set operating mode or determines an operating mode based on the indoor ambient temperature (for example, determining whether to operate in cooling mode or dehumidification mode based on the indoor ambient temperature), and then operates in the determined operating mode. For example, if the indoor environment is determined to be in a high temperature and high humidity state, the system operates in a user-selected operating mode or automatically selects a mode based on the indoor temperature.

[0042] If it is determined that the indoor environment is in a high temperature and high humidity state, the current equivalent perceived temperature is determined based on the detected indoor environment temperature and indoor relative humidity. Preferably, if it is determined that the indoor environment is in a high temperature and high humidity state, it is determined whether an instruction to run the cooling mode is received; if it is determined that an instruction to run the cooling mode is received, the current equivalent perceived temperature is determined based on the detected indoor environment temperature and indoor relative humidity. For example, if it is determined that the indoor environment is in a high temperature and high humidity state, it is determined whether a demand for cooling mode (i.e., an instruction to run the cooling mode) is received. If the demand received is not for cooling mode, it is operated according to the mode selected by the user. If the air conditioner receives a demand for cooling mode, the current equivalent perceived temperature is calculated.

[0043] In a specific embodiment, the current equivalent perceived temperature EPT is calculated according to the detected indoor ambient temperature and indoor relative humidity according to the following formula:

[0044] Equivalent sensible temperature EPT = T + k*(RH-a)*(Tb)

[0045] Where EPT is the equivalent perceived temperature, T is the indoor ambient temperature, RH is the indoor relative humidity, k is the equivalent perceived temperature coefficient, a is the preset upper limit of humidity for human comfort, and b is the preset upper limit of temperature for human comfort. (RH-a) is the humidity correction term, which reflects the effect of humidity on human comfort. The higher the humidity, the greater the equivalent perceived temperature. (Tb) is the temperature weight, indicating that the higher the temperature, the more significant the effect of humidity. The equivalent perceived temperature is used to quantify the actual human experience in high temperature and high humidity environments, with the main reference parameters being the indoor ambient temperature and indoor relative humidity.

[0046] For example, if k=0.07, a=60%, and b=25° C., then EPT=T+0.07*(RH-60%)*(T-25° C.).

[0047] Step S140: Control the air conditioner to enter a cooling mode or a cooling and dehumidification mixed mode according to the determined current equivalent sensible temperature.

[0048] Specifically, if the current equivalent perceived temperature is less than or equal to the preset temperature threshold, the air conditioner is controlled to enter the cooling mode; if the current equivalent perceived temperature is greater than the preset temperature threshold, the air conditioner is controlled to enter the cooling and dehumidification mixed mode. If the current equivalent perceived temperature is less than or equal to the preset temperature threshold, for example, when EPT < 32°C, the human body's perceived temperature is less affected by humidity, and the air conditioner operates in the default cooling mode; if the current equivalent perceived temperature is greater than the preset temperature threshold, for example, when EPT ≥ 32°C, the human body is in an uncomfortable state of high temperature and high humidity. At this time, the cooling effect of the air conditioner will be reduced due to the influence of humidity, and the air conditioner enters the cooling + dehumidification mixed mode.

[0049] After the air conditioner enters a mixed cooling and dehumidification mode, the compressor's operating frequency is increased to a preset frequency to increase the air conditioner's cooling capacity and enhance dehumidification. When the indoor ambient temperature is detected to have dropped to a preset temperature value, the internal fan speed is reduced to a preset value. The preset frequency may specifically be a preset maximum operating frequency of the compressor.

[0050] Specifically, after the air conditioner enters mixed cooling and dehumidification mode, it enters a high-efficiency cooling phase, initially achieving rapid cooling. This phase controls the compressor's high-frequency operation, increasing cooling capacity for rapid cooling, while simultaneously enhancing dehumidification through the low-temperature evaporator. Moisture in the air, upon contact with the evaporator, condenses into droplets due to the lowered temperature. These droplets are then drained through the air conditioner's drainage system, achieving dehumidification. The high-frequency operation of the compressor and the lowered evaporator temperature further enhance the condensation of moisture in the air, resulting in a more effective dehumidification effect.

[0051] During this phase, the indoor ambient temperature is monitored in real time. When the indoor ambient temperature drops to a preset value (e.g., 30°C), humidity has a more pronounced effect on regulating perceived temperature. Once the indoor ambient temperature drops to a preset value (e.g., 30°C), the air conditioner enters the high-efficiency dehumidification phase, reducing the fan speed and reducing both the inlet and outlet air speeds. This allows for a longer air residence time on the same path, increasing the air's contact time with the evaporator and improving the dehumidification effect.

[0052] According to the above-described embodiment of the present invention, when the air conditioner operates in a mixed cooling and dehumidification mode, it rapidly cools the air while enhancing dehumidification. After the temperature drops to a preset value (e.g., 30°C), the air conditioner's focus shifts to dehumidification, improving the dehumidification effect. Compared to pure cooling mode, the air conditioner's control logic incorporates control of the indoor fan. With the focus shifted to dehumidification, the air conditioner can significantly reduce perceived temperature in a relatively energy-efficient manner, making it more energy-efficient and intelligent.

[0053] To clearly illustrate the technical solution of the present invention, the execution process of the air conditioner control method provided by the present invention is described below with reference to a specific embodiment.

[0054] Figure 2 FIG. 1 is a schematic diagram of a specific embodiment of the air conditioning control method provided by the present invention. Figure 2 As shown, after the air conditioner receives the start-up control request, it judges whether the indoor ambient temperature and relative humidity are high temperature and high humidity. When the indoor ambient temperature T meets 26℃≤T≤40℃, the room is in a high temperature state; when the indoor ambient relative humidity RH meets 60%≤RH≤100%, the room is in a high humidity state; when the above two conditions are met at the same time, the indoor environment is in a high temperature and high humidity state.

[0055] When the indoor environment does not meet the high temperature and high humidity conditions, the air conditioner operates according to the operating mode selected by the user or automatically selects an operating mode based on the indoor temperature. If the indoor environment meets the high temperature and high humidity conditions, the air conditioner determines whether it has received a command to operate in cooling mode. If the command received is not for cooling mode, the air conditioner operates according to the user's selected mode. If the command received is for cooling mode, the air conditioner calculates the equivalent body temperature.

[0056] When the calculated equivalent sensible temperature EPT is ≤32℃, the human body's sensible temperature is less affected by humidity, and the air conditioner operates in the default cooling mode; when the calculated equivalent sensible temperature EPT is greater than 32℃, the human body is in an uncomfortable state of high temperature and high humidity. At this time, the cooling effect of the air conditioner will be reduced due to the influence of humidity, and the air conditioner will enter a mixed mode of cooling + dehumidification.

[0057] According to the above-mentioned embodiment of the present invention, the indoor temperature and humidity conditions are monitored in real time, and the actual experience of the current indoor occupants under high temperature and high humidity conditions is judged based on the calculated equivalent perceived temperature, so as to reasonably control the start and stop and operation of the cooling and dehumidification modes, thereby further reducing energy consumption.

[0058] In high-temperature and high-humidity environments, ambient temperature alone cannot accurately determine the human body's true perception of temperature. In high-humidity environments, operating in cooling mode alone can easily result in the actual perceived temperature being higher than the ambient temperature. This invention calculates the equivalent perceived temperature to determine the actual user experience in the current indoor environment under high-temperature and high-humidity conditions, thereby controlling the activation and operation of the air conditioner's cooling and dehumidification modes. This allows users to more quickly experience a comfortable temperature and humidity in high-temperature and high-humidity environments.

[0059] In high-temperature and high-humidity environments, air conditioners generate more condensed water, placing greater pressure on the drainage system. In mixed cooling and dehumidification mode, the present invention controls the compressor to operate at a high frequency, increasing the cooling capacity for rapid cooling while simultaneously lowering the evaporator temperature. This enhances the dehumidification effect and reduces the pressure on the drainage of condensed water.

[0060] The invention also provides a control device for an air conditioner.

[0061] Figure 3 FIG. 1 is a structural block diagram of an embodiment of the air conditioner control device provided by the present invention. Figure 3 As shown, the control device 100 includes: a detection unit 110 , a first judgment unit 120 , a first determination unit 130 and a control unit 140 .

[0062] The detection unit 110 is used to detect the indoor ambient temperature and indoor relative humidity after the air conditioner is started.

[0063] Specifically, when the air conditioner is started, it begins to detect the indoor ambient temperature and indoor relative humidity. When using the air conditioner, the user can start the air conditioner and select the mode and set the corresponding temperature through the remote control or mobile phone APP. The air conditioner indoor unit receives the information, executes the startup function, and detects the indoor ambient temperature and indoor relative humidity.

[0064] The first judgment unit 120 is configured to judge whether the indoor environment is in a high temperature and high humidity state according to the indoor environment temperature and indoor relative humidity detected by the detection unit 110 .

[0065] Specifically, when the indoor ambient temperature is within the preset temperature range and the indoor relative humidity is within the preset humidity range, the indoor environment is judged to be in a high temperature and high humidity state. For example, when the indoor ambient temperature T is in the range of 26°C ≤ T ≤ 40°C, the indoor environment is in a high temperature state. When the indoor relative humidity RH is in the range of 60% ≤ RH ≤ 100%, the indoor environment is in a high humidity state. When the above two conditions are met at the same time, the indoor environment is in a high temperature and high humidity state.

[0066] The first determining unit 130 is configured to determine a current equivalent perceived temperature based on the indoor ambient temperature and indoor relative humidity detected by the detecting unit 110 if the first determining unit 120 determines that the indoor environment is in a high temperature and high humidity state.

[0067] Optionally, the device 100 further includes a second determining unit (not shown) configured to, if the first determining unit 120 determines that the indoor environment is not in a high temperature and high humidity state, operate the air conditioner in a set operating mode or determine an operating mode based on the indoor ambient temperature. The control unit 140 is further configured to control the air conditioner to operate in the determined operating mode. For example, when the indoor environment is determined to be in a high temperature and high humidity state, the air conditioner operates in a user-selected operating mode or automatically selects a mode based on the indoor temperature.

[0068] If the first judgment unit 120 determines that the indoor environment is in a high temperature and high humidity state, the first determination unit 130 determines the current equivalent perceived temperature based on the detected indoor environment temperature and indoor relative humidity. Preferably, the device 100 also includes: a second judgment unit (not shown), which is used to determine whether an instruction to run the cooling mode is received if the first judgment unit 120 determines that the indoor environment is in a high temperature and high humidity state; the first determination unit 120 is further used to: if the second judgment unit determines that an instruction to run the cooling mode is received, determine the current equivalent perceived temperature based on the detected indoor environment temperature and indoor relative humidity. For example, if it is determined that the indoor environment is in a high temperature and high humidity state, it is determined whether a demand for the cooling mode (i.e., an instruction to run the cooling mode) is received. If the received demand is not for the cooling mode, it is operated according to the mode selected by the user. If the air conditioner receives a demand for the cooling mode, the current equivalent perceived temperature is calculated.

[0069] In a specific embodiment, the current equivalent perceived temperature EPT is calculated according to the detected indoor ambient temperature and indoor relative humidity according to the following formula:

[0070] Equivalent sensible temperature EPT = T + k*(RH-a)*(Tb)

[0071] Where EPT is the equivalent perceived temperature, T is the indoor ambient temperature, RH is the indoor relative humidity, k is the equivalent perceived temperature coefficient, a is the preset upper limit of humidity for human comfort, and b is the preset upper limit of temperature for human comfort. (RH-a) is the humidity correction term, which reflects the effect of humidity on human comfort. The higher the humidity, the greater the equivalent perceived temperature. (Tb) is the temperature weight, indicating that the higher the temperature, the more significant the effect of humidity. The equivalent perceived temperature is used to quantify the actual human experience in high temperature and high humidity environments, with the main reference parameters being the indoor ambient temperature and indoor relative humidity.

[0072] For example, if k=0.07, a=60%, and b=25° C., then EPT=T+0.07*(RH-60%)*(T-25° C.).

[0073] The control unit 140 is configured to control the air conditioner to enter a cooling mode or a cooling and dehumidification mixed mode according to the current equivalent sensible temperature determined by the first determining unit.

[0074] Specifically, if the current equivalent perceived temperature is less than or equal to the preset temperature threshold, the air conditioner is controlled to enter the cooling mode; if the current equivalent perceived temperature is greater than the preset temperature threshold, the air conditioner is controlled to enter the cooling and dehumidification mixed mode. If the current equivalent perceived temperature is less than or equal to the preset temperature threshold, for example, when EPT < 32°C, the human body's perceived temperature is less affected by humidity, and the air conditioner operates in the default cooling mode; if the current equivalent perceived temperature is greater than the preset temperature threshold, for example, when EPT ≥ 32°C, the human body is in an uncomfortable state of high temperature and high humidity. At this time, the cooling effect of the air conditioner will be reduced due to the influence of humidity, and the air conditioner enters the cooling + dehumidification mixed mode.

[0075] After the air conditioner enters a mixed cooling and dehumidification mode, the compressor's operating frequency is increased to a preset frequency to increase the air conditioner's cooling capacity and enhance dehumidification. When the indoor ambient temperature is detected to have dropped to a preset temperature value, the internal fan speed is reduced to a preset value. The preset frequency may specifically be a preset maximum operating frequency of the compressor.

[0076] Specifically, after the air conditioner enters mixed cooling and dehumidification mode, it enters a high-efficiency cooling phase, initially achieving rapid cooling. This phase controls the compressor's high-frequency operation, increasing cooling capacity for rapid cooling, while simultaneously enhancing dehumidification through the low-temperature evaporator. Moisture in the air, upon contact with the evaporator, condenses into droplets due to the lowered temperature. These droplets are then drained through the air conditioner's drainage system, achieving dehumidification. The high-frequency operation of the compressor and the lowered evaporator temperature further enhance the condensation of moisture in the air, resulting in a more effective dehumidification effect.

[0077] During this phase, the indoor ambient temperature is monitored in real time. When the indoor ambient temperature drops to a preset value (e.g., 30°C), humidity has a more pronounced effect on regulating perceived temperature. Once the indoor ambient temperature drops to a preset value (e.g., 30°C), the air conditioner enters the high-efficiency dehumidification phase, reducing the fan speed and reducing both the inlet and outlet air speeds. This allows for a longer air residence time on the same path, increasing the air's contact time with the evaporator and improving the dehumidification effect.

[0078] According to the above embodiment of the present invention, when the air conditioner operates in a mixed cooling and dehumidification mode, it quickly cools down while enhancing dehumidification. After the temperature drops to a preset temperature value (for example, 30°C), the air conditioner's focus shifts to dehumidification, thereby improving the dehumidification effect. Compared with the simple cooling mode, the control logic of the air conditioner adds the control of the indoor fan. At the same time, after the focus of the work shifts to dehumidification, it can have a more obvious effect on reducing the perceived temperature in a relatively energy-saving manner, which is more energy-saving and intelligent. The present invention also provides a storage medium corresponding to the control method of the air conditioner, on which a computer program is stored, and when the program is executed by a processor, the steps of any of the aforementioned methods are implemented.

[0079] According to the above-mentioned embodiment of the present invention, the indoor temperature and humidity conditions are monitored in real time, and the actual experience of the current indoor occupants under high temperature and high humidity conditions is judged based on the calculated equivalent perceived temperature, so as to reasonably control the start and stop and operation of the cooling and dehumidification modes, thereby further reducing energy consumption.

[0080] The present invention also provides an air conditioner corresponding to the air conditioner control method, comprising a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of any of the aforementioned methods when executing the program.

[0081] The present invention also provides an air conditioner corresponding to the control device of the air conditioner, comprising any of the aforementioned control devices of the air conditioner.

[0082] The present invention also provides a computer program product corresponding to the air conditioner control method, comprising a computer program, which implements the steps of any of the aforementioned methods when executed by a processor.

[0083] In high-temperature and high-humidity environments, ambient temperature alone cannot accurately determine the human body's true perception of temperature. In high-humidity environments, operating in cooling mode alone can easily result in the actual perceived temperature being higher than the ambient temperature. This invention calculates the equivalent perceived temperature to determine the actual user experience in the current indoor environment under high-temperature and high-humidity conditions, thereby controlling the activation and operation of the air conditioner's cooling and dehumidification modes. This allows users to more quickly experience a comfortable temperature and humidity in high-temperature and high-humidity environments.

[0084] In high-temperature and high-humidity environments, air conditioners generate more condensed water, placing greater pressure on the drainage system. In mixed cooling and dehumidification mode, the present invention controls the compressor to operate at a high frequency, increasing the cooling capacity for rapid cooling while simultaneously lowering the evaporator temperature. This enhances the dehumidification effect and reduces the pressure on the drainage of condensed water.
