[0024] In order to make the objectives, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0025] The air conditioner control method provided by the present embodiment has an execution subject of an air conditioner, which can be a mobile air conditioner or an indoor fixed air conditioner configured with the method function. In implementation, a user can operate a button on the air conditioner to trigger an energy-saving control instruction. Alternatively, the user can establish a communication connection with the air conditioner by using a control terminal, and then send an energy-saving control instruction to the air conditioner through the control terminal to control the air conditioner. The button on the air conditioner can be a physical button or a virtual button on the air conditioner display screen. The communication connection between the control terminal and the air conditioner can be established through near field communication, such as Bluetooth connection or NFC connection.

[0026] It should be noted that in actual application, the air conditioner can be powered by a battery pack or by mains. When the air conditioner is powered by a battery pack, the air conditioner control method according to the present embodiment can reduce the power consumption of the battery pack as much as possible and prolong the endurance of the battery pack. When the air conditioner is powered by mains, the air conditioner control method according to the present embodiment can reduce the power consumption of the air conditioner and achieve the effect of energy saving and emission reduction.

[0027] In actual use, when the air conditioner is cooling or heating, most of the power consumption comes from the compressor. Therefore, in order to prolong the use time of the battery pack or reduce the power consumption of the mains, when the air conditioner is running in the energy-saving mode, the frequency of the compressor can be reduced to reduce the power consumption of the air conditioner.

[0028] Based on this, the air conditioner control method provided by the embodiment is to obtain a preset first working frequency in response to an energy-saving control instruction, so that the current environment of the air conditioner can quickly reach the temperature set by the user, and the compressor of the air conditioner is controlled to work at the first working frequency, and the outlet temperature of the air conditioner is monitored. When the outlet temperature of the air conditioner reaches the set temperature value, the temperature change rate of the environment temperature is periodically detected to determine the cooling / heating effect of the air conditioner and the temperature maintaining effect of the current environment. If the temperature change rate is less than a preset first temperature change threshold, it indicates that the cooling / heating effect of the air conditioner and the temperature maintaining effect of the current environment are good, and then the working frequency of the compressor is reduced to avoid the battery pack being quickly depleted. The control strategy of the air conditioner is provided, the intelligent degree of the air conditioner is improved, the energy saving is maximized on the basis of ensuring the user experience, and the use time of the battery pack for supplying power to the air conditioner is prolonged.

[0029] It can be understood that in actual use, the air conditioner can also be powered by commercial power, and the energy-saving and emission-reducing effect can also be achieved by executing the air conditioner control method of the embodiment.

[0030] The air conditioner control method provided by the embodiment will be described in detail below through a specific implementation manner.

[0031] Figure 1 is an implementation flowchart of an air conditioner control method provided by an embodiment of the application. As shown in Figure 1 , the air conditioner control method comprises the following steps:

[0032] S11: obtaining a preset first working frequency in response to an energy-saving control instruction.

[0033] In step S11, the energy-saving control instruction is used to control the air conditioner to run in an energy-saving mode. The energy-saving mode trigger instruction can be sent by the user to the mobile air conditioner through a control terminal, or can be triggered by the user by operating the control keys of the mobile air conditioner.

[0034] Specifically, the first working frequency can be a pre-set air conditioner compressor control parameter, and the preset first working frequency must be within the rated working frequency range of the air conditioner compressor.

[0035] As an embodiment, obtaining the preset first working frequency can be to obtain the pre-configured rated working frequency from the memory of the air conditioner as the first working frequency.

[0036] It should be noted that, generally speaking, the compressor needs to be involved whether the air conditioner works in the cooling mode or in the heating mode. Here, when the air conditioner operates in the cooling mode, the gaseous refrigerant in the air conditioner is compressed by the compressor to become a high-temperature and high-pressure gas, and this part of the gas is sent into the condenser and then expanded by the expansion valve to dissipate part of the heat, that is, the hot air blown out of the air outlet of the air conditioner. In this process, the high-temperature and high-pressure refrigerant will sharply decrease in temperature and pressure due to the increase in space, absorbing a large amount of heat, and the temperature of the evaporator will be lowered, and then cold air (cold quantity) is output through the air outlet of the air conditioner. When the air conditioner operates in the heating mode, the high-temperature and high-pressure superheated steam compressed by the compressor is discharged from the exhaust port of the compressor, and then the superheated steam is directly sent into the evaporator from the connecting evaporator pipe. The superheated steam is then cooled by the heat exchanger, and the heat dissipated by the cross-flow fan is blown out from the air outlet. Based on this, since the power consumption of the air conditioner whether in cooling or heating depends on the working frequency of the compressor, the preset first working frequency can be specifically obtained as the first working frequency of the compressor in the rated frequency range.

[0037] It is easy to understand that, in the actual use of the air conditioner, different first working frequencies can be configured according to the cooling mode or the heating mode. Accordingly, in some embodiments, the corresponding first working frequency can also be obtained according to the different temperatures or different temperature adjustment modes of the air conditioner at present.

[0038] For example, if the current air conditioner temperature is the cooling temperature, or the air conditioner is in the cooling mode, the preset first working frequency of the air conditioner in the cooling mode is obtained; if the current air conditioner temperature is the heating temperature, or the air conditioner is in the heating mode, the preset first working frequency of the air conditioner in the heating mode is obtained; wherein the first working frequency in the cooling mode is not equal to the first working frequency in the heating mode.

[0039] Here, the first working frequency in the cooling mode can be the working frequency of the compressor corresponding to the lowest adjustable temperature of the air conditioner in the cooling mode; and the first working frequency in the heating mode can be the working frequency of the compressor corresponding to the highest adjustable temperature of the air conditioner in the heating mode.

[0040] In this embodiment, in order to bring better temperature adjustment experience to the user in the energy-saving mode, after obtaining the preset first working frequency, the compressor of the air conditioner can be controlled to work according to the preset first working frequency, so that the environmental temperature can quickly reach the temperature value set by the user.

[0041] S12: controlling the compressor of the air conditioner to work according to the first working frequency, and monitoring the outlet temperature of the air conditioner.

[0042] In step S12, the outlet air temperature of the air conditioner is used to represent the real-time output cooling or heating capacity of the compressor of the air conditioner when the compressor operates at the first operating frequency.

[0043] Specifically, detecting the outlet air temperature of the air conditioner can be to configure a temperature sensor, such as an infrared temperature sensor, at the outlet of the air conditioner, and use the infrared temperature sensor to collect the blowing temperature of the outlet of the air conditioner.

[0044] In a specific implementation, at least one temperature sensor can be arranged to monitor the outlet air temperature of the air conditioner according to the shape or position of the outlet of the air conditioner. It can be understood that when the outlet of the air conditioner is provided with multiple temperature sensors, the average value of the temperature values collected by the multiple temperature sensors can be calculated to obtain the outlet air temperature of the air conditioner.

[0045] It should be noted that, whether in cooling or heating, when the user sets the cooling temperature or heating temperature of the air conditioner, the ambient temperature changes with the cooling or heating capacity output by the air conditioner. When the outlet air temperature reaches the temperature value set by the user, it can be considered whether to adjust the frequency of the compressor to save energy.

[0046] S13: periodically detecting the temperature change rate of the ambient temperature when the outlet air temperature reaches the set temperature value.

[0047] In step S13, the temperature change rate of the ambient temperature is used to represent the cooling / heating effect of the air conditioner and the heat preservation effect of the current operating environment of the air conditioner. Specifically, the higher the temperature change rate of the ambient temperature, the worse the cooling / heating effect of the air conditioner and the heat preservation effect of the current operating environment of the air conditioner; if the temperature change rate of the ambient temperature is lower, the better the cooling / heating effect of the air conditioner and the heat preservation effect of the current operating environment of the air conditioner.

[0048] In this embodiment, the temperature change rate of the ambient temperature is calculated based on the ambient temperature. Here, unlike the outlet air temperature, the ambient temperature refers to the temperature of the current operating environment of the air conditioner, i.e. the space temperature of the current environment of the air conditioner, rather than the outlet temperature of the air conditioner. Because when the user uses the air conditioner, the current ambient temperature of the air conditioner directly affects the user's body temperature, when the space of the current operating environment of the air conditioner is large and the running time of the air conditioner is short, there can be a large temperature difference between the outlet air temperature of the air conditioner and the ambient temperature, so in the energy-saving mode, the outlet air temperature of the air conditioner cannot be considered alone when adjusting the operating frequency of the compressor. In this embodiment, by periodically detecting the temperature change rate of the ambient temperature when the outlet air temperature reaches the set temperature value, the heat preservation effect of the environment is considered in the temperature adjustment effect of the air conditioner during the temperature adjustment process of the air conditioner, so that the basis for adjusting the operating frequency of the compressor is more reasonable and the degree of scientificity is higher.

[0049] In a specific implementation, a temperature sensor can be used to collect multiple sets of temperature values in the current operating environment of the air conditioner, and the temperature change rate of the ambient temperature can be determined according to the change trend of each set of temperature values over time.

[0050] As an example, the first time is when the outlet temperature reaches the set temperature value, the ambient temperature T1 is collected at the first time, and the ambient temperature T2 is collected at the second time which is a unit time length away from the first time, and the temperature change rate of the ambient temperature in a single period can be obtained by calculating the difference between T1 and T2.

[0051] In some embodiments, the temperature change rate of the ambient temperature is periodically detected, and the ambient temperature of N positions in the current environment can be collected at the first time, and the average of the N ambient temperature values can be calculated as the ambient temperature at the first time. Similarly, the ambient temperature of N positions in the current environment can be collected at the second time, and the average of the N ambient temperature values can be calculated as the ambient temperature at the second time. The temperature change rate of the ambient temperature in a single period can be obtained by calculating the difference between the ambient temperature at the first time and the ambient temperature at the second time.

[0052] As an example, when detecting the temperature change rate of the ambient temperature, the temperature rise rate of the environment or the temperature drop rate of the environment can also be detected.

[0053] For example, if the current air conditioner is operating the compressor at the maximum frequency in the cooling mode, the ambient temperature is collected to calculate the ambient temperature change value, and the temperature rise rate of the environment is specifically observed.

[0054] For another example, if the current air conditioner is operating the compressor at the maximum frequency in the heating mode, the ambient temperature is collected to calculate the ambient temperature change value, and the temperature drop rate of the environment is specifically observed.

[0055] Taking two periods t0 to t2 as an example, let the ambient temperature collected at t0 be T0, the ambient temperature collected at t1 be T1, and the ambient temperature collected at t2 be T2. The temperature change rate of the ambient temperature in the first period t0 to t1 in the cooling mode can be △T1 = T1 - T0. Similarly, the temperature change rate of the ambient temperature in the second period t1 to t2 can be △T2 = T2 - T1. The temperature change rate of the ambient temperature in the first period t0 to t1 in the heating mode can be △T1 = T0 - T1. Similarly, the temperature change rate of the ambient temperature in the second period t1 to t2 can be △T2 = T1 - T2.

[0056] S14: If the temperature change rate is less than a preset first temperature change threshold, the operating frequency of the compressor is reduced.

[0057] In the embodiment, when the temperature change rate is less than the preset first temperature change threshold, it indicates that the cooling / heating effect of the air conditioner is better at this time, and in order to play the energy saving effect, the endurance of the battery pack for powering the air conditioner can be prolonged by reducing the working frequency of the compressor, or the power consumption of the air conditioner from the mains is reduced.

[0058] As an example, the first temperature change threshold can be the lower limit value of the temperature change threshold interval. As an example, the temperature change threshold interval ΔT [-1, 1], wherein -1 is the lower limit value in the temperature change threshold interval, that is, -1 is the first temperature change threshold, and 1 is the upper limit value in the temperature change threshold interval. When the temperature change rate is less than -1, the working frequency of the compressor is reduced.

[0059] In other embodiments, when the temperature change rate is within the range of the first temperature change threshold ΔT, it indicates that the ambient temperature is in a relatively stable stage, and the working frequency of the compressor is kept unchanged.

[0060] In some embodiments, the first temperature change threshold can be set according to the requirements of actual application scenarios.

[0061] Taking the first temperature change threshold of -1℃ as an example, assuming that the temperature of the air outlet of the air conditioner at t0 is 24℃, and the ambient temperature collected at t0 is 28℃. The ambient temperature collected at t1 is 26.5℃, and the ambient temperature collected at t2 is 25℃.

[0062] Correspondingly, the calculated ΔT1=-1.5 and ΔT2=-1.5 are both less than -1, so the ambient temperature change rate is low at this time, the heat preservation effect of the air conditioner environment is good, and the cooling effect is obvious, so reducing the working frequency of the compressor at this time will not cause the ambient temperature to rise rapidly, that is, the ambient temperature will not deviate from the set temperature quickly.

[0063] As an example, step S14 includes:

[0064] If the temperature change rate is less than the preset first temperature change threshold, and the working frequency of the compressor is greater than the preset minimum working frequency, the working frequency of the compressor is reduced; if the temperature change rate is less than the preset first temperature change threshold, and the working frequency of the compressor is equal to the minimum working frequency, the compressor is turned off.

[0065] In the embodiment, since the temperature change rate is less than the preset first temperature change threshold, it indicates that the cooling / heating effect of the air conditioner is good and the current environment insulation effect is good, so the power can be saved by reducing the working frequency of the compressor. Based on this, on the one hand, if the working frequency of the compressor at this time is greater than the preset minimum working frequency, the working frequency of the compressor can be further reduced. On the other hand, if the working frequency of the compressor at this time is equal to the minimum working frequency, the compressor is turned off. It can be understood that if the working frequency of the compressor is further reduced and the reduced working frequency is less than the preset minimum working frequency, the compressor can also be directly turned off.

[0066] It is easy to understand that when the compressor is turned off, the air conditioner is not completely powered off at this time, so the change rate of the environment temperature can still be detected as the basis for starting the compressor to work next time.

[0067] As an embodiment, after the compressor is turned off, the method of the embodiment can further include:

[0068] When the environment temperature is greater than the preset temperature threshold, the compressor of the air conditioner is controlled to work at the minimum working frequency, and the step of periodically detecting the temperature change rate of the environment temperature is returned to be executed.

[0069] In the embodiment, the air conditioner works in the cooling mode, it is assumed that the insulation effect of the current running environment of the air conditioner is good, but since the compressor has not been started for a long time, the temperature of the current environment gradually rises, so when the environment temperature is greater than the preset temperature threshold, the compressor is controlled to work at the minimum working frequency, which can make the air conditioner cool again to adjust the current environment temperature. At the same time, the temperature change rate of the environment temperature is periodically detected to return to execute, which can continue the energy-saving strategy of controlling the working frequency of the compressor.

[0070] Please refer to Figure 2 , Figure 2 is an implementation flowchart of an air conditioner control method provided by another embodiment of the application. Compared with Figure 1 the corresponding embodiment, Figure 2 the air conditioner control method shown in the figure further includes step S21 after step S13. As Figure 2 shown, specifically:

[0071] S21: If the temperature change rate is equal to or greater than the preset second temperature change threshold, the working frequency of the compressor is increased.

[0072] In the embodiment, the second temperature change threshold is used to represent the temperature change occasion for increasing the working frequency of the compressor. When the temperature change rate is equal to or greater than the preset second temperature change threshold, it indicates that the working frequency of the current compressor cannot meet the temperature adjustment requirement of the environment. Therefore, by increasing the working frequency of the compressor, the refrigeration or heating of the compressor can be further controlled to meet the temperature adjustment requirement of the environment as much as possible.

[0073] As an example, the first temperature change threshold can be the lower limit of the temperature change threshold interval. As an example, the temperature change threshold interval ΔT [-1, 1], wherein -1 is the lower limit of the temperature change threshold interval, i.e., -1 is the first temperature change threshold, and 1 is the upper limit of the temperature change threshold interval, i.e., 1 is the second temperature change threshold. When the temperature change rate is equal to or greater than 1, the working frequency of the compressor is increased.

[0074] In a specific implementation, increasing the working frequency of the compressor can be gradually adjusting the working frequency of the compressor according to a preset frequency increment. For example, a corresponding frequency increment is configured for different compressor frequencies. When increasing the working frequency of the compressor, a corresponding frequency increment can be superimposed according to the current frequency of the compressor, and then the increased frequency is determined, and the compressor is controlled to work at the increased frequency.

[0075] As an example, step S21 includes:

[0076] If the temperature change rate is greater than the preset second temperature change threshold, and the working frequency of the compressor is less than the maximum working frequency, the working frequency of the compressor is increased. If the temperature change rate is greater than the preset second temperature change threshold, and the working frequency of the compressor is equal to the maximum working frequency, the working frequency of the compressor is maintained.

[0077] In the embodiment, since when the temperature change rate is equal to or greater than the preset second temperature change threshold, it indicates that the working frequency of the current compressor cannot meet the temperature adjustment requirement of the environment, therefore, only by increasing the working frequency of the compressor can the air conditioner meet the current temperature adjustment requirement as much as possible. At this time, in order to ensure the safety of the operation of the air conditioner, it is necessary to further consider whether the current working frequency of the compressor is within the maximum working frequency. If the working frequency of the compressor is less than the maximum working frequency, the working frequency of the compressor is allowed to be increased. If the working frequency of the compressor is equal to the maximum working frequency, the working frequency of the compressor is prohibited to be further increased, and the working frequency of the compressor is maintained, i.e., the compressor continues to work at the maximum working frequency.

[0078] In some embodiments, after the compressor is turned off, the method can further include:

[0079] When the temperature change rate is greater than the second temperature change threshold, the compressor of the air conditioner is controlled to operate at the minimum operating frequency, and the step of periodically detecting the temperature change rate of the ambient temperature is performed.

[0080] In the embodiment, when the compressor is turned off, if the current environment has poor insulation performance, the ambient temperature can change rapidly with time. Based on this, if the temperature change rate is greater than the second temperature change threshold after the compressor is turned off, it indicates that the ambient temperature changes rapidly. In order to ensure the temperature regulation requirement of the user and reduce the energy consumption, the compressor of the air conditioner is controlled to operate at the minimum operating frequency, thereby regulating the ambient temperature while avoiding the compressor to operate at a high operating frequency, thereby further reducing the energy consumption of the air conditioner.

[0081] It can be understood that after the compressor is restarted at the minimum operating frequency, the operating frequency of the compressor can be gradually adjusted according to the temperature change rate of the ambient temperature, so as to reduce the temperature change rate of the ambient temperature and make the ambient temperature stabilize at the required temperature (i.e., the set temperature) of the user.

[0082] Please refer to Figure 3 , Figure 3 is an implementation flowchart of an air conditioner control method provided by another embodiment of the present application. Compared with Figure 2 the corresponding embodiment, Figure 3 the air conditioner control method shown in the embodiment further includes a step S31 after step S13. As Figure 3 shown, specifically:

[0083] S31: If the temperature change rate is greater than the first temperature change threshold and the temperature change rate is less than the second temperature change threshold, the operating frequency of the compressor is maintained.

[0084] In step S31, the first temperature change threshold and the second temperature change threshold serve as a temperature change threshold interval. For example, the temperature change threshold interval ΔT [-1, 1], wherein -1 is the lower limit value in the temperature change threshold interval, i.e., -1 is the first temperature change threshold, and 1 is the upper limit value in the temperature change threshold interval, i.e., 1 is the second temperature change threshold.

[0085] In this embodiment, if the rate of temperature change is greater than a first temperature change threshold and less than a second temperature change threshold, it indicates that the current rate of temperature change is within the temperature change threshold range. Here, when the rate of temperature change is within this temperature change threshold range, it indicates that the current ambient temperature is in a relatively stable stage. Therefore, maintaining the compressor's operating frequency can further reduce the energy consumption of the air conditioner.
