[0050] With the continuous improvement of production technology and the continuous growth of user demand, the popularity and frequency of use of air conditioners in various scenarios are also increasing. As a high-power electrical appliance, facing the growing demand for energy conservation 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 for air conditioner manufacturers.

[0051] The existing air conditioning energy-saving control method usually achieves the purpose of air conditioning energy saving by obtaining the ambient temperature and the reference temperature and continuously adjusting the set temperature according to the difference between the ambient temperature and the reference temperature.

[0052] However, such air-conditioning energy-saving control method has a slow response speed, and the corresponding control has a certain lag. It cannot flexibly control the air-conditioning according to the current usage situation, and the energy-saving effect needs to be improved.

[0053] In response to the above problems, the present invention proposes the following technical concept: according to the indoor ambient temperature of the air-conditioning indoor unit, determine whether it is necessary to perform energy-saving control on the cooling / heating program executed by the air-conditioning; if energy-saving control is required, adjust the operating frequency of the compressor of the air-conditioning according to the difference between the indoor ambient temperature of the air-conditioning indoor unit and the set temperature, so as to perform energy-saving control on the cooling / heating program executed by the air-conditioning in time at the appropriate time, improve the accuracy and sensitivity of energy-saving control, and take into account the user experience and the needs of energy saving and emission reduction.

[0054] Figure 1 Schematic diagram of the process of the air conditioning energy saving control method provided in the embodiment of the present application Figure 1 ;like Figure 1 As shown, the air conditioning energy saving control method provided in the embodiment of the present application includes:

[0055] S101: Acquire the indoor ambient temperature of the air conditioner.

[0056] It is understandable that before turning on the energy-saving control, the air-conditioning device needs to obtain the current indoor ambient temperature to determine whether the energy-saving control needs to be turned on.

[0057] Specifically, the air-conditioning equipment sends a control instruction to the temperature sensor, controls the temperature sensor to detect the indoor ambient temperature of the air-conditioning, and obtains the indoor ambient temperature detected by the temperature sensor; wherein the temperature sensor can be set on the main body of the air-conditioning equipment, or can be set at other indoor locations outside the main body of the air-conditioning equipment, and establishes a communication connection with the air-conditioning equipment.

[0058] S102: Determine whether it is necessary to adjust the operating frequency of the compressor of the air conditioner according to the indoor ambient temperature.

[0059] Specifically, the air-conditioning equipment determines whether it is necessary to adjust the operating frequency of the compressor of the air-conditioning according to the indoor ambient temperature and a preset judgment algorithm, wherein the preset judgment algorithm can, for example, be used to determine whether the current value of the indoor ambient temperature is within a preset temperature range, or to determine whether the changing trend of the indoor ambient temperature over a period of time meets preset conditions, or to determine whether the difference between the indoor ambient temperature and the outdoor ambient temperature is within a preset difference range; this embodiment does not limit the specific content of the preset judgment algorithm.

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

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

[0062] It can be understood that the set temperature is set manually by the user or pre-set in the program selected by the user. It can be considered that the set temperature is the user's expected value of the indoor ambient temperature. Therefore, the operating frequency of the compressor can be adjusted according to the absolute value of the difference between the indoor ambient temperature and the set temperature. In order to appropriately reduce the energy consumption of the air-conditioning equipment according to the gap between the current actual indoor ambient temperature and the user's expectations, so as to avoid affecting the user's 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 the preset control algorithm, so that the compressor adjusts its operating frequency according to the control instruction, wherein the preset control algorithm can, for example, obtain the target operating frequency of the compressor according to a preset correspondence between different first differences and different operating frequencies; it can also obtain the frequency control instruction of the classification corresponding to the first difference according to a pre-established classification rule for different first differences; this embodiment does not limit the specific content of the preset control algorithm.

[0064] The air conditioner energy-saving control method provided in the embodiment of the present application determines whether it is necessary to adjust the operating frequency of the compressor of the air conditioner according to the indoor ambient temperature of the air conditioner; when the operating frequency needs to be adjusted, the absolute value of the difference between the indoor ambient temperature and the 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 conditioner can be timely turned on at the right time, and the operating frequency can be accurately controlled according to the current indoor temperature conditions, so as to achieve the purpose of energy saving and emission reduction while ensuring user experience.

[0065] Figure 2 Schematic diagram of the process of the air conditioning energy saving control method provided in the embodiment of the present application Figure 2 ;like Figure 2 As shown, the air conditioning energy saving control method provided in the embodiment of the present application includes:

[0066] S201: After obtaining the air-conditioning start instruction, obtain the outdoor ambient temperature.

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

[0068] Specifically, the air-conditioning equipment sends a control instruction to a temperature sensor located outdoors, controls the temperature sensor to detect the outdoor ambient temperature of the air-conditioning, and obtains the outdoor ambient temperature detected by the temperature sensor; wherein the temperature sensor can be set on the main body of the outdoor unit of the air-conditioning equipment, or can be set at other outdoor locations outside the main body of the outdoor unit of the air-conditioning equipment, and establishes a communication connection with the air-conditioning equipment.

[0069] S202: Determine an initial operating frequency of the compressor according to the outdoor ambient temperature.

[0070] Among them, different outdoor ambient temperatures correspond to different initial operating frequencies.

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

[0072] S203: Controlling the compressor of the air conditioner to operate at the initial operating frequency.

[0073] 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 operates at the initial operating frequency according to the control instruction.

[0074] S204: Obtaining the personal information of the room where the air conditioner is located, and determining whether there is anyone in the room; if so, executing step S205; if not, executing step S206.

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

[0076] Specifically, the air-conditioning equipment sends a control instruction to a human body sensing device located indoors, controlling the human body sensing device to detect whether there is someone in the room where the air-conditioning is located; wherein the human body sensing device can be arranged on the main body of the outdoor unit of the air-conditioning equipment, or can be arranged at other outdoor locations outside the main body of the outdoor unit of the air-conditioning equipment, and establish a communication connection with the air-conditioning equipment; the human body sensing device can be, for example, a far-infrared sensor or a radar sensor, and this embodiment does not limit the specific form of the human body sensing device.

[0077] S205: If there is someone in the room, control the compressor to operate at a default operating frequency.

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

[0079] Specifically, if the human body sensing device detects that there is someone in the room, the air conditioning device controls the compressor to operate at a 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 timing, and after the timing reaches a preset time, obtain the indoor ambient temperature of the air conditioner.

[0081] It can be understood that if there is no one in the room, the time when no one is in the room can be counted to determine whether no one is in the room for a long time, so as to determine whether energy saving can be turned on; when the timing time reaches the preset time, it can be considered that no one has been in the room for a long time. At this time, continuing to run according to the default program may cause energy waste, and since there is no one in the room, the energy saving control has little impact on the user experience, and the energy saving control can be turned on.

[0082] Specifically, if the human body sensing device detects that there is no one in the room, the air conditioning device controls the timing device to start timing, and the timing is used to record the duration of no one in the room. Once the human body sensing device detects that there is someone in the room, the timing is stopped and reset to zero. When the timing duration reaches a preset duration, the air conditioning device controls the temperature sensor in the room to obtain the indoor ambient temperature of the air conditioner.

[0083] S207: according to a preset cycle, determine whether the indoor environment temperature is between the target temperature and the set temperature. If yes, execute step S208; if no, continue to execute step 207.

[0084] Wherein, the first target temperature in the cooling mode is higher than the set temperature, and 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 makes the human body feel more comfortable. In general, when the air conditioner performs the heating program, from the start to the end of the first preset cycle, the indoor ambient temperature is always in the range of less than or equal to the set temperature; when the air conditioner performs the cooling program, from the start to the end of the first preset cycle, the indoor ambient temperature is always in the range of more than or equal to the set temperature. When the air conditioner performs the heating program, the temperature range that the human body feels more comfortable can be, for example, 20 degrees and above. If the indoor temperature is lower than 20 degrees, most people will feel cold. Usually, when the air conditioner performs the heating program, the set temperature will be higher than 20 degrees, and the range of the indoor ambient temperature that can be allowed to fluctuate can be between the set temperature and 20 degrees. When the air conditioner performs the cooling program, the temperature that the human body feels more comfortable can be, for example, 27 degrees and below. If the indoor temperature is higher than 27 degrees, most people will feel hot. Usually, when the air conditioner performs the cooling program, the set temperature will be lower than 27 degrees, and the range of the indoor ambient 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 ambient temperature is between the target temperature and the set temperature, it can be considered that the current indoor ambient temperature is still within a comfortable temperature range. At this time, energy-saving control can be appropriately turned on without causing a significant impact on the experience of users who may enter the room later, that is, determining to adjust the compressor operating frequency of the air conditioner.

[0086] Specifically, the air conditioning device controls the temperature sensor in the room to obtain the indoor ambient temperature according to a preset period, and determines whether the value of the indoor ambient temperature is between the value of the target temperature and the value of the set temperature.

[0087] S208: Obtain a first difference value, and determine whether the first difference value is less than a preset difference value. If so, execute step S209; if not, execute step S210.

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

[0089] Specifically, the air conditioning device reads the currently running program information, obtains the set temperature, and calculates the first difference according to the indoor ambient temperature and the set temperature; and compares the first difference with the preset difference.

[0090] S209: If the first difference is less than a preset difference, reducing the operating frequency of the compressor to a minimum operating frequency.

[0091] It can be understood that if the first difference is smaller than the preset difference, it can be considered that the gap between the current indoor ambient temperature and the set temperature is small, and the gap between the current indoor ambient temperature and the target temperature is large. Even if the indoor ambient temperature fluctuates greatly due to energy saving, it will not exceed the comfortable temperature range. The air conditioner has a large room for reducing efficiency. At this time, the operating frequency of the compressor can be reduced to the minimum operating frequency.

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

[0093] S210: If the difference is greater than or equal to a preset difference, a temperature condition parameter is obtained, and a target operating frequency of the compressor is determined 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 gap between the current indoor ambient temperature and the set temperature is large, and the gap between the current indoor ambient temperature and the target temperature is small. If energy saving causes large fluctuations in the indoor ambient temperature, the indoor ambient temperature may exceed the comfortable temperature range, and the air conditioner can reduce efficiency. There is a large room. At this time, the temperature condition parameters can be obtained, and the target operating frequency of the compressor can be determined based on the temperature condition parameters to accurately adjust the operating frequency of the compressor to avoid energy saving affecting the experience of users who may enter the room later.

[0095] The temperature condition parameter includes the first difference and the 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 for determining the target operating frequency of the compressor according to the temperature condition parameter may be, for example:

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

[0098] Step 2: Obtain the target operating frequency of the compressor according to the product of the ratio and the initial compression 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 ambient temperature, T t is the target temperature, f 0 is the initial operating frequency.

[0100] It can be understood that, when the set temperature and the target temperature are constant values, the smaller the gap between the indoor ambient temperature and the set temperature, the greater the fluctuation of the indoor ambient temperature caused by energy saving allowed at the current ambient temperature, the greater the frequency range that the compressor can reduce, and the smaller the corresponding target operating frequency, that is, the target operating frequency is directly proportional to the first difference; and if the preset target temperature is larger, the gap between it and the set temperature is larger, that is, the preset comfort temperature range is larger, the greater the fluctuation of the indoor ambient temperature caused by energy saving allowed, the greater the frequency range that the compressor can reduce, and the smaller the corresponding target operating frequency, it can be considered that the target operating frequency is inversely proportional to the second difference; therefore, the target operating frequency of the compressor after frequency reduction can be determined based on the initial operating frequency according to the mapping relationship expressed by the function.

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

[0102] Among them, the preset duration is greater than the duration of N cycles, N is greater than or equal to 2, and the preset duration is not greater than 1 / M of the startup duration, wherein the startup duration is the duration from the start of the air conditioner to before adjustment, and M is not less than 2.

[0103] It is understandable that after the air conditioner frequency reduction reaches a certain degree or duration, usually, the gap between the indoor ambient temperature and the set temperature will gradually increase, and may even rise or fall outside the comfortable temperature range, which may make users who enter the room later feel uncomfortable. Therefore, the first frequency adjustment can be used as the starting point. After a preset period of time, if the current indoor ambient temperature obtained is not between the target temperature and the set temperature, the compressor is controlled to work at the initial operating frequency again, so that the indoor ambient temperature can quickly recover to a comfortable temperature range; and in order to ensure the effect of air conditioning energy-saving control and avoid frequent adjustments to the compressor operating frequency that cause frequent fluctuations in the indoor ambient temperature, the preset time should not be too long or too short, and can be greater than the length of N cycles, where N is greater than or equal to 2, and not greater than 1 / M of the startup time, wherein the startup time is the time from the start of the air conditioner to before the adjustment, and M is not less than 2.

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

[0105] The air conditioner energy-saving control method provided in the embodiment of the present application ensures that the energy-saving control of the air conditioner is turned on in time by determining whether to adjust the operating frequency of the compressor of the air conditioner according to the indoor personnel situation and the indoor ambient temperature; determines the target operating frequency of the compressor of the air conditioner according to the temperature condition parameters, and reduces the frequency of the compressor according to the target operating frequency, and after the frequency reduction reaches a preset time, determines whether to restore the operating frequency of the compressor to the default frequency according to the indoor ambient temperature, so that the frequency adjustment of the compressor is more accurate and sensitive, ensuring the energy-saving effect while ensuring the user experience of the air conditioner.
