[0050] With the continuous improvement of production technology and the growing demand of users, the popularization rate and use frequency of air conditioners in various scenes are also increasing. As a high-power electrical appliance, air conditioners face the growing demand of energy saving and emission reduction in modern society. How to reduce the energy consumption of air conditioners while ensuring the use effect is of great practical significance to air conditioner manufacturers.

[0051] The existing air conditioner energy saving control method usually obtains the ambient temperature and the reference temperature, and continuously adjusts the set temperature according to the difference between the ambient temperature and the reference temperature, so as to realize the purpose of air conditioner energy saving.

[0052] However, such air conditioner energy saving control method has slow response speed, corresponding control has certain hysteresis, cannot flexibly control the air conditioner according to the current use condition, and the energy saving effect needs to be improved.

[0053] In view of the above problems, the present application proposes the following technical concept: according to the indoor environment temperature where the air conditioner indoor unit is located, it is determined whether the cooling / heating program executed by the air conditioner needs to be controlled for energy saving; if energy saving control is needed, the running frequency of the compressor of the air conditioner is adjusted according to the difference between the indoor environment temperature where the air conditioner indoor unit is located and the set temperature, so as to timely control the cooling / heating program executed by the air conditioner at the appropriate time, improve the precision and sensitivity of energy saving control, and balance the user's use experience and the demand of energy saving and emission reduction.

[0054] Figure 1 Flowchart of air conditioner energy saving control method provided by the embodiment of the present application Figure 1 As shown in the figure, the air conditioner energy saving control method provided by the embodiment of the present application comprises: Figure 1

[0055] S101: obtaining the indoor environment temperature where the air conditioner is located.

[0056] It can be understood that before starting the energy saving control, the air conditioner device needs to obtain the current indoor environment temperature to determine whether the energy saving control needs to be started at present.

[0057] Specifically, the air conditioner device sends a control instruction to the temperature sensor to control the temperature sensor to detect the indoor environment temperature where the air conditioner is located, and obtains the indoor environment temperature detected by the temperature sensor; wherein the temperature sensor can be arranged on the body of the air conditioner device, or can be arranged at other positions in the room except the body of the air conditioner device, and is in communication connection with the air conditioner device.

[0058] S102: judging whether the running frequency of the compressor of the air conditioner needs to be adjusted according to the indoor environment temperature.

[0059] ​Specifically, the air conditioning device determines whether to adjust the operating frequency of the compressor of the air conditioning device according to the indoor environment temperature and a preset determination algorithm. The preset determination algorithm may be, for example, determining whether the current value of the indoor environment temperature is within a preset temperature range, determining whether the change trend of the indoor environment temperature within a period of time meets a preset condition, or determining whether the difference between the indoor environment temperature and the outdoor environment temperature is within a preset difference range. The embodiment is not limited in terms of the specific content of the preset determination algorithm.

[0060] S103: If yes, a first difference is obtained, and the operating frequency of the compressor is adjusted according to the first difference.

[0061] The first difference is the absolute value of the difference between the indoor environment temperature and a set temperature.

[0062] It can be understood that the set temperature is manually set by a user or preset in a program selected by the user. The set temperature can be considered as the expected value of the indoor environment temperature by the user. Therefore, the operating frequency of the compressor can be adjusted according to the absolute value of the difference between the indoor environment temperature and the set temperature, so as to moderately reduce the energy consumption of the air conditioning device according to the difference between the actual indoor environment temperature and the expectation of the user, and avoid affecting the user experience.

[0063] Specifically, the air conditioning device sends a control instruction to the compressor of the air conditioning device according to the first difference and a preset control algorithm, so that the compressor adjusts the operating frequency according to the control instruction. The preset control algorithm may be, for example, obtaining a target operating frequency of the compressor according to a preset correspondence between different first differences and different operating frequencies, or obtaining a frequency control instruction corresponding to the classification of the first difference according to a preset classification rule of different first differences. The embodiment is not limited in terms of the specific content of the preset control algorithm.

[0064] The air conditioning energy-saving control method provided in the embodiment can determine whether to adjust the operating frequency of the compressor of the air conditioning device according to the indoor environment temperature of the air conditioning device. When the operating frequency needs to be adjusted, the absolute value of the difference between the indoor environment temperature and a set temperature is obtained, and the operating frequency of the compressor is adjusted according to the difference, so that the energy-saving control of the air conditioning device can be started in time at an appropriate time, and the operating frequency can be accurately controlled according to the temperature condition of the indoor environment, so as to achieve the purpose of energy saving and emission reduction on the premise of ensuring the user experience.

[0065] Figure 2 Flowchart of the air conditioning energy-saving control method provided in the embodiment Figure 2 ; asFigure 2 The air conditioner energy-saving control method provided by the embodiment of the present application comprises:

[0066] S201: After obtaining an air conditioner starting instruction, an outdoor environment temperature is obtained.

[0067] The outdoor environment temperature is used to indicate the environment temperature of the outdoor where the outdoor unit of the air conditioner is located.

[0068] Specifically, the air conditioner device sends a control instruction to a temperature sensor located outdoors, controls the temperature sensor to detect the outdoor environment temperature where the air conditioner is located, and obtains the outdoor environment temperature detected by the temperature sensor; wherein the temperature sensor can be arranged on the body of the outdoor unit of the air conditioner device, or can be arranged at other positions outdoors other than the body of the outdoor unit of the air conditioner device, and is in communication connection with the air conditioner device.

[0069] S202: According to the outdoor environment temperature, the initial running frequency of the compressor is determined.

[0070] Different outdoor environment temperatures correspond to different initial running frequencies.

[0071] Specifically, the air conditioner device determines the initial running frequency of the compressor corresponding to the outdoor environment temperature according to the preset correspondence between different outdoor environment temperatures and different initial running frequencies.

[0072] S203: The compressor of the air conditioner is controlled to work at the initial running frequency.

[0073] Specifically, the air conditioner device sends a control instruction to the compressor of the air conditioner according to the first difference and a preset control algorithm, so that the compressor works at the initial running frequency according to the control instruction.

[0074] S204: Personnel information in the room where the air conditioner is located is obtained, and it is determined whether there is anyone in the room; if yes, step S205 is executed; if no, step S206 is executed.

[0075] The personnel information is used to indicate whether there is anyone in the room.

[0076] Specifically, the air conditioner device sends a control instruction to a human body sensing device located indoors, controls the human body sensing device to detect whether there is anyone in the room where the air conditioner is located; wherein the human body sensing device can be arranged on the body of the outdoor unit of the air conditioner device, or can be arranged at other positions outdoors other than the body of the outdoor unit of the air conditioner device, and is in communication connection with the air conditioner device; the human body sensing device can be, for example, a far-infrared sensor or a radar sensor, and the embodiment does not limit the specific form of the human body sensing device.

[0077] S205: If there are people in the room, control the compressor to run at the default operating frequency.

[0078] Understandably, if there are people in the room, in order to ensure that the user experience is not affected, the compressor can be controlled to run at the frequency specified by the control algorithm of the cooling / heating program selected by the user, that is, at the default operating frequency corresponding to the program.

[0079] Specifically, if the human body sensor detects that someone is in the room, the air conditioning equipment controls the compressor to run at the default operating frequency corresponding to the program, according to the control algorithm of the currently running cooling / heating program.

[0080] S206: If no one is in the room, start the timer, and after the timer reaches the preset duration, obtain the indoor ambient temperature where the air conditioner is located.

[0081] Understandably, if no one is in the room, the timer can be started to determine whether the room has been unoccupied for an extended period of time, and whether energy saving can be activated. When the timer reaches the preset duration, it can be considered that the room has been unoccupied for an extended period of time. Continuing to run the default program at this time may result in energy waste. Since no one is in the room, the impact of energy saving control on user experience is relatively small, and energy saving control can be activated.

[0082] Specifically, if the human body sensor detects that no one is in the room, the air conditioning unit controls the timing device to start timing. The timing is used to record the duration of no one being in the room. Once the human body sensor detects that someone is in the room, it stops timing and resets the timer to zero. After the preset time has elapsed, the air conditioning unit controls the indoor temperature sensor to obtain the indoor ambient temperature where the air conditioner is located.

[0083] S207: Determine whether the indoor ambient temperature is between the target temperature and the set temperature according to a preset cycle. If yes, proceed to step S208; otherwise, continue to step S207.

[0084] The first target temperature in the cooling mode is higher than the set temperature, the second target temperature in the heating mode is lower than the set temperature, the target temperature is used to indicate the critical temperature of the temperature range that people feel more comfortable, and generally, when the air conditioner executes the heating program, the indoor environment temperature is always in the range of lower than or equal to the set temperature from the start to the end of the first preset period; when the air conditioner executes the cooling program, the indoor environment temperature is always in the range of higher than or equal to the set temperature from the start to the end of the first preset period. When the air conditioner executes the heating program, the temperature range that people feel more comfortable can be, for example, 20 degrees and above. If the indoor temperature is lower than 20 degrees, most people will feel cold. Generally, when the air conditioner executes the heating program, the set temperature is higher than 20 degrees, and the range of the indoor environment temperature that can be allowed to fluctuate can be between the set temperature and 20 degrees. When the air conditioner executes the cooling program, the temperature range that people feel more comfortable can be, for example, 27 degrees and below. If the indoor temperature is higher than 27 degrees, most people will feel hot. Generally, when the air conditioner executes the cooling program, the set temperature is lower than 27 degrees, and the range of the indoor environment temperature that can be allowed to fluctuate can be between 27 degrees and the set temperature.

[0085] It can be understood that if the indoor environment temperature is between the target temperature and the set temperature, it can be considered that the current indoor environment temperature is still in the temperature range that people feel comfortable, at this time, the energy-saving control can be appropriately started without causing great influence on the experience of the subsequent users who may enter the room, that is, it is determined to adjust the running frequency of the compressor of the air conditioner.

[0086] Specifically, the air conditioner controls the temperature sensor in the room to obtain the indoor environment temperature according to the preset period, and judges whether the value of the indoor environment temperature is between the value of the target temperature and the value of the set temperature.

[0087] S208: Obtain the first difference value, judge whether the first difference value is less than the preset difference value, if yes, execute step S209; if no, execute step S210.

[0088] The first difference value is the absolute value of the difference between the indoor environment temperature and the set temperature, and the first difference value can reflect the gap between the current indoor temperature and the set temperature.

[0089] Specifically, the air conditioner reads the program information of the current running, obtains the set temperature, and calculates the first difference value according to the indoor environment temperature and the set temperature; compares the first difference value with the preset difference value.

[0090] S209: If the first difference value is less than the preset difference value, the running frequency of the compressor is reduced to the minimum running frequency.

[0091] It can be understood that if the first difference is less than the preset difference, it can be considered that the difference between the current indoor environment temperature and the set temperature is small, and the difference between the current indoor environment temperature and the target temperature is large, even if the indoor environment temperature fluctuates greatly due to energy saving, it will not exceed the comfortable temperature range, and the air conditioner can reduce the efficiency space, at this time, the operating frequency of the compressor can be reduced to the minimum operating frequency.

[0092] Specifically, if the first difference is less than the preset difference, the air conditioning equipment controls the compressor to reduce its operating frequency to the minimum operating frequency.

[0093] S210: If the difference is greater than or equal to the preset difference, obtain a temperature condition parameter, and determine the target operating frequency of the compressor according to the temperature condition parameter.

[0094] It can be understood that if the first difference is greater than or equal to the preset difference, it can be considered that the difference between the current indoor environment temperature and the set temperature is large, and the difference between the current indoor environment temperature and the target temperature is small, if the indoor environment temperature fluctuates greatly due to energy saving, it may exceed the comfortable temperature range, and the air conditioner can reduce the efficiency space, at this time, the temperature condition parameter can be obtained, and the target operating frequency of the compressor can be determined according to the temperature condition parameter, so as to accurately adjust the operating frequency of the compressor, and avoid affecting the experience of the user who may enter the indoor environment later due to energy saving.

[0095] The temperature condition parameter includes the first difference and a second difference, and the second difference is the absolute value of the difference between the target temperature and the set temperature.

[0096] Optionally, the specific method steps of determining the target operating frequency of the compressor according to the temperature condition parameter can be, for example:

[0097] Step 1: Obtain the ratio of the first difference and the second difference.

[0098] Step 2: Obtain the target operating frequency of the compressor according to the product of the ratio and the initial compressor operating frequency, that is,

[0099] Wherein, f is the target operating frequency of the compressor, T s is the set temperature, T r is the indoor environment temperature, T t is the target temperature, and f0 is the initial operating frequency.

[0100] It can be understood that, in the case of setting the temperature and the target temperature as constants, the smaller the gap between the indoor environment temperature and the set temperature, the greater the fluctuation of the indoor environment temperature allowed by energy saving at the current environment temperature, the greater the frequency range that the compressor can be reduced, and the smaller the corresponding target operating frequency, i.e., the target operating frequency is in direct proportion to the first difference; and the greater the preset target temperature, the greater the gap between the target temperature and the set temperature, i.e., the greater the preset comfortable temperature range, the greater the fluctuation of the indoor environment temperature allowed by energy saving, the greater the frequency range that the compressor can be reduced, and the smaller the corresponding target operating frequency, which can be considered as being in inverse proportion to the second difference; therefore, the target operating frequency of the compressor after frequency reduction can be determined on the basis of the initial operating frequency according to the mapping relationship expressed by the function.

[0101] S211: Taking the first frequency adjustment as a starting point, after a preset time period, if the current indoor environment temperature is not between the target temperature and the set temperature, the compressor is controlled to work at the initial operating frequency again.

[0102] The preset time period is greater than the time period of N cycles, N is greater than or equal to 2, and the preset time period is not greater than 1 / M of the startup time period, M is not less than 2.

[0103] It can be understood that, in the case of setting the temperature and the target temperature as constants, the smaller the gap between the indoor environment temperature and the set temperature, the greater the fluctuation of the indoor environment temperature allowed by energy saving at the current environment temperature, the greater the frequency range that the compressor can be reduced, and the smaller the corresponding target operating frequency, i.e., the target operating frequency is in direct proportion to the first difference; and the greater the preset target temperature, the greater the gap between the target temperature and the set temperature, i.e., the greater the preset comfortable temperature range, the greater the fluctuation of the indoor environment temperature allowed by energy saving, the greater the frequency range that the compressor can be reduced, and the smaller the corresponding target operating frequency, which can be considered as being in inverse proportion to the second difference; therefore, the target operating frequency of the compressor after frequency reduction can be determined on the basis of the initial operating frequency according to the mapping relationship expressed by the function.

[0104] Specifically, taking the first frequency adjustment as a starting point, after a preset time length, the air conditioning device controls the temperature sensor in the room to obtain the indoor environment temperature, and judges whether the value of the indoor environment temperature is still between the value of the target temperature and the value of the set temperature; if the current indoor environment temperature is not between the target temperature and the set temperature, the air conditioning device controls the compressor to run at the default running frequency corresponding to the current cooling / heating program.

[0105] The air conditioning energy-saving control method provided by the embodiments of the present application ensures the timely start of the energy-saving control of the air conditioner by determining whether to adjust the running frequency of the compressor of the air conditioner according to the indoor personnel situation and the indoor environment temperature situation; the target running frequency of the compressor of the air conditioner is determined according to the temperature condition parameter, the frequency of the compressor is reduced according to the target running frequency, and after the reduction reaches a preset time length, it is judged according to the indoor environment temperature whether to restore the running frequency of the compressor to the default frequency, so that the frequency adjustment of the compressor is more accurate and sensitive, and the user experience of the air conditioner is ensured while the energy-saving effect is ensured.
