[0073] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0074] It's important to note that multi-split air conditioning systems are currently widely used in various types of buildings, including commercial, office, and residential buildings, due to their high efficiency and flexibility. A multi-split air conditioning system uses one or more outdoor units connected to multiple indoor units of varying or identical types and capacities, directly exchanging heat with the indoor air through the refrigerant. It's particularly suitable for buildings with a large number of rooms, requiring long-term temperature control, and demanding high comfort levels.

[0075] However, in real life, people may move between rooms, making it easy for rooms to be empty or for the number of people in a room to fluctuate significantly. If the air conditioning system continues to operate at the user-set temperature when the room is unoccupied, it can easily waste energy. Large fluctuations in the number of people in a room can cause significant changes in the room load, causing the room temperature to drop or rise. The air conditioning system can only respond after the room temperature has changed, resulting in a delayed response and reduced comfort for occupants.

[0076] In response to the current problem that it is difficult to intelligently adjust the air-conditioning system according to changes in personnel, this application aims to provide an air-conditioning control method. By detecting personnel information in the target area, the air-conditioning system can be intelligently adjusted according to the personnel scene. On the one hand, for unmanned scenes, the set temperature of the air-conditioning system can be intelligently adjusted based on the target temperature of the air-conditioning system, while taking into account the comfort of personnel and improving the energy-saving effect of the system; on the other hand, for personnel flow scenes, the operating parameters of the target components can be adjusted in time according to the change rate of the number of people, thereby quickly responding to load changes caused by personnel changes, and effectively improving the comfort of indoor personnel.

[0077] It should be noted that the order of description of the following embodiments does not limit the priority order of the embodiments.

[0078] Figure 1 The following schematically illustrates a flow chart of an air conditioning control method according to an embodiment of the present application. The execution subject of the air conditioning control method can be any electronic device with data processing, network communication, and program execution functions, such as an air conditioning controller of an air conditioning system, or other electronic devices used to perform air conditioning control, such as a computer, mobile terminal, smart home, cloud server, etc.

[0079] Reference Figure 1 , shows an air conditioning control method of the present application, which may specifically include the following steps:

[0080] S101: Determine a target personnel scene based on personnel information in a target area.

[0081] In this embodiment, there can be one or more target areas, each of which is equipped with an indoor unit of the air conditioning system for environmental conditioning. The air conditioning system can be a single-unit or split-unit air conditioner equipped with only one indoor unit. In this case, it is sufficient to monitor the flow of people in the target area where the indoor unit is located. The air conditioning system can also be a multi-connected air conditioning system equipped with multiple indoor units. In this case, by monitoring the flow of people in multiple target areas, the multiple indoor units can be used to perform targeted environmental conditioning in each target area to meet the environmental conditioning needs of each target area. This embodiment does not impose specific restrictions on the number of target areas or the type of air conditioning system.

[0082] In this embodiment, a camera may be installed in the room to capture moving images of people, and the information of people in the target area may be identified using an image recognition algorithm.

[0083] In this embodiment, an RFID (Radio Frequency Identification) reader can also be installed in the room, and personnel are equipped with cards, wristbands or badges containing RFID tags. When a person with a tag enters or leaves the room, the reader automatically reads the identity information in the tag and then identifies the flow of people in the target area.

[0084] In this embodiment, infrared sensors, radar sensors and other sensors may also be used to sense the vital signs of people in the room, thereby realizing detection and presence status judgment of people in the room.

[0085] In this embodiment, the personnel information includes the number of personnel. By real-time monitoring of the number of personnel, accurate identification of target personnel scenes can be achieved. Specifically, the target personnel scenes may include unmanned scenes and personnel flow scenes.

[0086] S102: When the target personnel scene is an unmanned scene, adjusting the set temperature of the air-conditioning system based on the target temperature of the air-conditioning system.

[0087] In this embodiment, after detecting that the target area is unoccupied, in order to avoid the air-conditioning system from continuously running at the initial set temperature set by the user and causing energy waste, a suitable target temperature will be determined for the air-conditioning system to adjust the set temperature of the air-conditioning system.

[0088] For example, if the air-conditioning system is in heating mode, after detecting that the target area is in an unmanned scene, the target temperature is determined to be a temperature value lower than the initial set temperature at the start time of the unmanned scene, and the set temperature of the air-conditioning system is gradually lowered so that the set temperature of the air-conditioning system gradually approaches the target temperature; if the air-conditioning system is in cooling mode, after detecting that the target area is in an unmanned scene, the target temperature is determined to be a temperature value higher than the initial set temperature at the start time of the unmanned scene, and the set temperature of the air-conditioning system is gradually increased so that the set temperature of the air-conditioning system gradually approaches the target temperature.

[0089] In this embodiment, by adjusting the set temperature of the air-conditioning system based on the target temperature of the air-conditioning system in an unmanned scene, intelligent adjustment of the set temperature can be achieved, thereby improving the energy saving effect.

[0090] In this embodiment, if it is detected that the set temperature of the air-conditioning system reaches the target temperature, the set temperature of the air-conditioning system is maintained unchanged; if during the process of adjusting the set temperature of the air-conditioning system based on the target temperature of the air-conditioning system, that is, before the set temperature of the air-conditioning system reaches the target temperature, it is detected that there are people in the target area, the adjustment is stopped, and the set temperature of the air-conditioning system is reset to the initial set temperature at the start time of the unmanned scene to meet the user's comfort needs.

[0091] In this embodiment, compared with directly shutting down the air-conditioning system or directly adjusting the set temperature of the air-conditioning system to the target temperature, by gradually adjusting the set temperature of the air-conditioning system, both system energy saving and user comfort can be effectively taken into account.

[0092] S103: When the target personnel scene is a personnel flow scene, the operating parameters of the target components of the air-conditioning system are adjusted based on the change rate of the number of people in the target area.

[0093] In this embodiment, after detecting that the target area is in a personnel flow scene, the population change rate of the target area will be calculated, and then the operating parameters of the target components of the air-conditioning system will be actively adaptively adjusted based on the population change rate to quickly respond to the load changes caused by the flow of people in multiple spaces.

[0094] It should be noted that the target components are components used to adjust the space load in the air-conditioning system, including but not limited to components such as the compressor and the indoor unit expansion valve.

[0095] In this embodiment, considering that different occupancy rate changes will result in varying degrees of load changes in the target area, and that different components of the air conditioning system have different load adjustment capabilities, different target components can be matched to different occupancy rate changes for targeted adjustment. In other words, the target component requiring adjustment and its operating parameters can be determined based on the occupancy rate change in the target area, and then the target component can be adjusted based on these operating parameters.

[0096] In this embodiment, compared with the method of waiting for the ambient temperature to change significantly before adjusting the temperature of the air-conditioning system, by using the personnel flow as a feedforward condition to adjust the operating parameters of the target components of the air-conditioning system, it is possible to achieve rapid and accurate adjustment of the space load.

[0097] In this embodiment, by detecting the personnel information of the target area, the air-conditioning system can be intelligently adjusted under different personnel scenarios. On the one hand, for unmanned scenarios, the set temperature of the air-conditioning system can be intelligently adjusted based on the target temperature of the air-conditioning system, while taking into account the comfort of the personnel and improving the energy-saving effect of the system; on the other hand, for the personnel flow scenario, the operating parameters of the target components can be adjusted in time according to the change rate of the number of people, thereby quickly responding to the load changes caused by personnel changes, and effectively improving the comfort of indoor personnel.

[0098] In one feasible embodiment, the target temperature may be determined based on the following method:

[0099] S201: Acquire multiple historical set temperatures of the air-conditioning system in the current mode.

[0100] It should be noted that the target temperature can be determined by the electronic device that performs air conditioning control, or it can be determined by another electronic device. In this case, the electronic device that performs air conditioning control can be in communication with the other electronic device to obtain the target temperature determined by the other electronic device. For example, the electronic device that performs air conditioning control can obtain the target temperature determined by the air conditioning control panel or the environmental monitoring system. This embodiment does not limit the entity that performs the determination of the target temperature.

[0101] In this embodiment, the current mode may be a heating mode or a cooling mode.

[0102] In this embodiment, multiple historical set temperatures can be updated in a time-series rolling manner. Specifically, a temperature data pool can be set to store multiple historical set temperatures, including a heating temperature pool set for the heating mode and a cooling temperature pool set for the cooling mode.

[0103] In a specific implementation, the number of historical set temperatures in the temperature data pool can be set to a fixed value. For example, the number of historical set temperatures in the temperature data pool can be set to 30, which will only record the 30 most recent historical set temperatures set by the user. When the number in the temperature data pool reaches 30, if the user sets the set temperature of the air conditioning system again, the set temperature will be added to the temperature data pool as the latest historical set temperature, and the historical set temperature added earliest in the temperature data pool will be deleted, thus achieving a rolling update of the historical set temperatures. In this way, it can effectively adapt to changes in user temperature habits and ensure that the target temperature meets the user's recent temperature adjustment habits.

[0104] S202: Sort multiple historical set temperatures to obtain a temperature sequence.

[0105] In this embodiment, the plurality of historical set temperatures may be sorted according to a preset sorting method, such as descending order or ascending order, to obtain a temperature sequence.

[0106] S203: Determine the historical set temperature at a preset position in the temperature sequence as the target temperature.

[0107] In this embodiment, the preset position can use a fixed position number. For example, when the number of temperature data pools is 30, the preset position can be set to No. 25, that is, the historical set temperature at No. 25 in the temperature sequence is selected as the target temperature.

[0108] In this embodiment, the preset position can be determined based on a preset ratio and the number of historical set temperatures. For example, the preset ratio can be set to 90%. If the number of temperature data pools is 30, the preset position is (90% × 30 =) 27, i.e., the 27th historical set temperature in the temperature sequence is selected as the target temperature. It should be noted that if a decimal point appears in the preset position, it is rounded up. For example, if the calculated value is 27.5, the preset position is 28.

[0109] In this embodiment, to facilitate subsequent determination of an appropriate target temperature using a unified selection method, the multiple historical set temperatures for the heating mode can be arranged in descending order, while the multiple historical set temperatures for the cooling mode can be arranged in ascending order. In this case, the target temperature can be selected from a historical set temperature at the end of the temperature sequence. Alternatively, the multiple historical set temperatures for the heating mode can be arranged in ascending order, while the multiple historical set temperatures for the cooling mode can be arranged in descending order. In this case, the target temperature can be selected from a historical set temperature at the beginning of the temperature sequence. In this way, based on the same selection strategy, when the current mode is heating mode, a historical set temperature with a lower value in the heating mode can be selected as the target temperature, and when the current mode is cooling mode, a historical set temperature with a higher value in the cooling mode can be selected as the target temperature, thereby effectively ensuring energy saving.

[0110] In this embodiment, by sorting multiple historical set temperatures in the current mode, a suitable target temperature can be determined in the temperature sequence, thereby improving energy saving while ensuring comfort.

[0111] In one feasible embodiment, the step of adjusting the set temperature of the air-conditioning system based on the target temperature of the air-conditioning system in S102 may specifically include the following sub-steps:

[0112] S102-1: When the duration of the unmanned scene is greater than a first duration threshold, determine the current set temperature at every preset time interval based on the duration of the unmanned scene, the target temperature, and the initial set temperature at the start time of the unmanned scene.

[0113] In this embodiment, when it is detected that the target personnel scene is an unmanned scene, the timing of the duration of the unmanned scene will be triggered. If the duration reaches the first duration threshold, it means that the person will not return to the target area in a short time, thereby triggering gradual temperature adjustment.

[0114] In this embodiment, by setting a first time threshold, it is possible to effectively prevent frequent temperature adjustments caused by users frequently entering and exiting the target area within a short period of time. For example, the first time threshold can be set to 30 minutes. If the duration of the unmanned scene exceeds 30 minutes, the temperature is automatically adjusted gradually to achieve energy conservation. Otherwise, the initial temperature setting at the start of the unmanned scene is maintained, ensuring that the room temperature remains unchanged when the user returns to the room.

[0115] In this embodiment, after the progressive temperature adjustment is triggered, the set temperature of the air-conditioning system can be adjusted once every preset time interval, and the temperature adjustment can be performed at the appropriate time to avoid excessive temperature adjustment and affect the system energy efficiency.

[0116] In this embodiment, when performing temperature adjustment, by comprehensively considering the duration of the unmanned scene, the target temperature and the initial set temperature at the start of the unmanned scene, a suitable current set temperature can be determined so that the current set temperature can gradually approach the target temperature.

[0117] In specific implementation, the current set temperature can be calculated according to the following formula:

[0118]

[0119] Among them, T set Indicates the current set temperature of the air conditioning system, in °C; T set,∞ Indicates the target temperature of the air conditioning system, in °C; T set,0 Indicates the initial set temperature at the beginning of the unmanned scene, in °C; τ represents the adjustment time constant, which is used to adjust the speed of the set temperature change.

[0120] In this embodiment, τ can be customized based on actual needs to balance the comfort and energy efficiency of the air conditioning system. For example, if τ is set to 1 hour, assuming the initial set temperature at the start of the unmanned scene is 24°C and the target temperature is 28°C, then after several adjustments, the set temperature at 1 hour is 26.5°C, and the preset adjustment duration is 10 minutes.

[0121] In this embodiment, the air conditioning system can also be turned off when the duration of the unmanned scene is greater than the second duration threshold and no adjustment instruction for the air conditioning system is received; wherein the second duration threshold is greater than the first duration threshold.

[0122] In this embodiment, when the duration of the unmanned scene is greater than the second time threshold, it means that the people in the target area have not returned for a long time. At this time, if no adjustment instructions for the air-conditioning system are received, it means that the people no longer have the need to use air conditioning, and the air-conditioning system is directly turned off to avoid energy waste.

[0123] S102-2: Control the set temperature of the air conditioning system to adjust to the current set temperature.

[0124] In this embodiment, after the current set temperature is calculated, the set temperature of the air-conditioning system can be adjusted to the current set temperature to achieve a gradual adjustment of the ambient temperature.

[0125] In an energy efficiency test experiment, taking a 10HP multi-split system as an example, the system was set to enter progressive temperature control at 30 minutes and shut down at 180 minutes. The target temperature was 28°C. The test obtained the energy efficiency improvement ratio when the initial set temperature was 24°C, as shown in the following example: Figure 2 shown.

[0126] In another energy efficiency test experiment, taking a 10HP multi-split air conditioning system as an example, the system was set to enter progressive temperature adjustment at 30 minutes and shut down at 180 minutes, with the target temperature being 28°C. The test obtained the energy efficiency improvement ratio when the initial set temperature was 23°C, as shown in the following example: Figure 3 shown.

[0127] In this embodiment, for unmanned scenarios, gradual temperature adjustment can effectively improve the energy saving effect of the system while taking into account the comfort of personnel.

[0128] In one feasible implementation, the rate of change of the number of people in the target area may be determined based on the following method:

[0129] S301: Obtain the current number of people in the target area in the current time period and the historical number of people in the target area in the previous time period of the current time period.

[0130] It should be noted that the rate of change in the number of people in the target area can be determined by the electronic device that performs air conditioning control, or it can be determined by other electronic devices. In this case, the electronic device that performs air conditioning control can be connected to the other electronic devices to obtain the rate of change in the number of people in the target area determined by the other electronic devices. For example, the electronic device that performs air conditioning control can obtain the rate of change in the number of people in the target area determined by the monitoring system. This embodiment does not limit the entity that performs the determination of the rate of change in the number of people in the target area.

[0131] In this embodiment, for any time period, one or more target area population values ​​can be collected. When multiple population values ​​are collected for the time period, that is, when there is a change in the population of the target area, the average of the multiple population values ​​can be determined as the population value for the time period.

[0132] S302: The ratio of the difference between the current population value and the historical population value to the current population value is determined as the population change rate of the target area.

[0133] In this embodiment, the change rate of the number of people in the target area can be calculated according to the following formula:

[0134] P=|(Φ n -Φ n-1 ) / Φ n | (2);

[0135] Where P represents the rate of change of the number of people in the target area; Φ n Indicates the current number of people in the target area during the current period; Φ n-1 Indicates the historical population value of the target area in the previous period of the current period.

[0136] In this embodiment, compared with the traditional method of using the difference between the current number of people and the historical number of people as the rate of change of the number of people, by adopting the ratio calculation method, it is possible to more accurately reflect the extent of personnel changes, and then accurately predict the load changes that may be caused by personnel flow, and achieve precise adjustment of the operating parameters of the target components.

[0137] In one feasible embodiment, the step of adjusting the operating parameters of the target components of the air-conditioning system based on the change rate of the number of people in the target area in S103 may specifically include the following sub-steps:

[0138] S103 - 1 : When the change rate of the number of people in the target area is greater than a change rate threshold, the operating frequency of the compressor of the air-conditioning system is adjusted.

[0139] In this embodiment, when the rate of change of the number of people in the target area is greater than the rate of change threshold, it means that the change in the number of people is more significant and the spatial load has increased or decreased significantly. At this time, in order to quickly respond to a large number of load changes, the target component is determined to be the compressor, and then the operating frequency of the compressor is adjusted.

[0140] It should be noted that the compressor is the core component of the air-conditioning system. Its main function is to compress the low-temperature, low-pressure gas refrigerant from the evaporator, so that the pressure and temperature of the refrigerant increase. The high-pressure and high-temperature refrigerant gas then enters the condenser, providing an energy basis for the subsequent links of the refrigeration cycle.

[0141] In this embodiment, the adjustment value of the compressor's operating frequency can be determined based on the rate of change in the number of people; a target operating frequency is then obtained based on the adjustment value and the current operating frequency of the compressor; and the compressor's operating frequency is adjusted based on the target operating frequency. In a specific implementation, a PID or fuzzy control method is used to determine the adjustment value of the compressor's operating frequency based on the rate of change in the number of people.

[0142] In this embodiment, when the rate of change in the number of people is high, such as when the number of people increases significantly, the heat dissipated by human bodies and respiration can rapidly increase the indoor heat load. In this case, to meet the cooling (or heating) needs of the room, the refrigerant circulation rate needs to be increased. By increasing the compressor operating frequency, the refrigerant circulation rate in the system can be accelerated, allowing more refrigerant to absorb indoor heat through the evaporator (in cooling mode) or release heat through the condenser (in heating mode) per unit time. For example, in a conference room, if the number of people increases from 10 to 50, the indoor temperature may rise by several degrees Celsius in a short period of time if not adjusted in a timely manner. In this case, by increasing the compressor frequency, the air conditioning system can quickly increase the cooling capacity and maintain the indoor temperature within a comfortable range. Conversely, when the number of people decreases significantly, the indoor heat load decreases. Reducing the compressor operating frequency can reduce the refrigerant circulation rate, avoid excessive cooling or heating, and thus achieve energy conservation while maintaining a stable indoor temperature and providing a comfortable indoor environment.

[0143] S103 - 2 : When the change rate of the number of people in the target area is less than or equal to the change rate threshold, adjust the opening of the expansion valve of the indoor unit of the air-conditioning system.

[0144] In this embodiment, when the rate of change in the number of people in the target area is less than or equal to the rate of change threshold, the change in the number of people is relatively insignificant, and the spatial load within a single room is not significantly changing. In this case, load allocation between different spaces within the same system is more necessary. Therefore, the compressor frequency is maintained unchanged, and the indoor unit expansion valve is identified as the target component. The opening of the indoor unit expansion valve is adjusted to achieve reasonable load distribution.

[0145] It's important to note that the indoor unit expansion valve is a key component in the air conditioning and refrigeration system, primarily responsible for throttling and reducing pressure. It throttles and reduces the pressure of the high-pressure liquid refrigerant exiting the condenser, converting it into a low-pressure, low-temperature liquid refrigerant, preparing it for heat absorption in the evaporator. For example, in cooling mode, the refrigerant temperature after passing through the expansion valve may drop from the higher temperature at the condenser outlet (e.g., around 50-60°C) to a low temperature near 0°C. This also reduces the pressure, paving the way for evaporation in the evaporator.

[0146] In this embodiment, if the number of people in the target area remains constant, adjusting the opening of the indoor unit's expansion valve allows for fine-tuning of the refrigerant flow rate in the evaporator, thereby regulating the evaporator's superheat. During operation, adjusting the expansion valve opening changes the amount of refrigerant entering the evaporator, thereby more precisely controlling the evaporation pressure and temperature. For example, if the number of people in the room increases slightly, causing the indoor temperature to rise, the expansion valve opening can be appropriately increased to allow more refrigerant to enter the evaporator, absorbing more heat and maintaining a stable indoor temperature. This avoids system instability and energy waste caused by frequent adjustments to the compressor frequency, achieving more energy-efficient and precise temperature control.

[0147] In this embodiment, the appropriate target component can be determined for adjustment based on the size relationship between the rate of change of the number of people and the change rate threshold, thereby meeting the environmental adjustment needs in different personnel flow scenarios.

[0148] In one feasible implementation, the step of adjusting the opening of the expansion valve of the indoor unit of the air-conditioning system in S103-2 may specifically include the following sub-steps:

[0149] S103-2-1: Obtain the current indoor ambient temperature, historical indoor ambient temperature, current set temperature and the number of people in the target area.

[0150] In this embodiment, the number of people in the target area can be obtained by performing human body recognition on an image of the target area using image recognition technology, or determined based on radar signals collected by a radar sensor.

[0151] S103-2-2: Determine the target superheat of the evaporator of the air conditioning system based on the current indoor ambient temperature, the historical indoor ambient temperature, the current set temperature and the number of people.

[0152] In this embodiment, the difference between the current indoor ambient temperature and historical indoor ambient temperatures is calculated to reflect changes in the indoor ambient temperature. The difference between the current indoor ambient temperature and the current set temperature is calculated to reflect the difference between the current indoor ambient temperature and the ideal temperature. The number of people in the target area reflects the load caused by human activity. Therefore, by comprehensively considering the current indoor ambient temperature, historical indoor ambient temperatures, the current set temperature, and the number of people, an appropriate target superheat degree can be determined.

[0153] It's important to note that evaporator superheat refers to the difference between the actual refrigerant vapor temperature at the evaporator outlet and the saturation temperature at the corresponding evaporation pressure. It's a key parameter in measuring the evaporation of refrigerant within the evaporator in a refrigeration system. The indoor unit expansion valve is a throttling element installed in front of the evaporator. It regulates the amount of liquid refrigerant entering the evaporator by controlling the refrigerant flow rate.

[0154] It's important to further explain that when the indoor unit's expansion valve opening increases, more liquid refrigerant flows into the evaporator per unit time. If the evaporator's heat load remains constant, the refrigerant flow rate entering the evaporator increases, accelerating the evaporation rate within the evaporator. Because refrigerant evaporation requires heat absorption, the refrigerant vapor temperature at the evaporator outlet decreases, reducing superheat, given a constant heat load. Conversely, when the indoor unit's expansion valve opening decreases, the liquid refrigerant flow rate entering the evaporator decreases, slowing the evaporation rate. However, given the same heat load, the refrigerant vapor temperature at the evaporator outlet increases, increasing superheat.

[0155] In a specific implementation, to further improve the adjustment accuracy, the historical indoor ambient temperature includes a first historical temperature and a second historical temperature. The first historical temperature is the indoor ambient temperature in the previous statistical period before the current indoor ambient temperature; the second historical temperature is the indoor ambient temperature in the previous statistical period before the first historical temperature.

[0156] In this embodiment, the target superheat of the evaporator is determined based on the current indoor ambient temperature, the historical indoor ambient temperature, the current set temperature and the number of people, which may specifically include: determining a first temperature difference based on the current indoor ambient temperature and the first historical temperature; determining a second temperature difference based on the current indoor ambient temperature and the current set temperature; determining a third temperature difference based on the current indoor ambient temperature, the first historical temperature and the second historical temperature; determining a number adjustment coefficient based on the number of people; and determining the target superheat based on the first temperature difference, the second temperature difference, the third temperature difference and the number adjustment coefficient.

[0157] In a specific implementation, a first adjustment coefficient corresponding to the first temperature difference, a second adjustment coefficient corresponding to the second temperature difference, and a third adjustment coefficient corresponding to the third temperature difference can be obtained. An initial superheat is then determined based on the first temperature difference, the first adjustment coefficient, the second temperature difference, the second adjustment coefficient, the third temperature difference, and the third adjustment coefficient. Finally, a target superheat is determined based on the number of passengers adjustment coefficient and the initial superheat. Specifically, the target superheat of the evaporator can be determined according to the following formula:

[0158]

[0159] in, Indicates the target superheat of the evaporator; Tn Indicates the current indoor unit ambient temperature; T n-1 Indicates the first historical temperature; T n-2 Indicates the second historical temperature; T st Indicates the current set temperature; K at Indicates the number of people adjustment coefficient; m p Represents the first adjustment coefficient; m k Represents the second adjustment coefficient; m d Represents the third adjustment coefficient.

[0160] It should be noted that T n -2T n-1 +T n-2 =(T n -T n-1 )-(T n-1 -T n-2 ), that is, the third temperature difference can reflect the change between the two temperature change amplitudes corresponding to three consecutive statistical periods.

[0161] In this embodiment, by performing weighted summation on the first temperature difference, the second temperature difference, and the third temperature difference, and correcting the weighted summation result using the number of people adjustment coefficient, the accuracy of the target superheat can be ensured, thereby improving the comfort of indoor occupants.

[0162] S103-2-3: Adjust the opening of the indoor unit expansion valve to make the evaporator reach the target superheat.

[0163] In this embodiment, by adjusting the opening of the indoor unit expansion valve, the evaporator can be controlled to increase or decrease, and ultimately achieve the target superheat.

[0164] For example, when reducing the evaporator's superheat, the expansion valve opening can be increased, allowing more liquid refrigerant to flow into the evaporator. This provides the refrigerant with more opportunities to absorb heat and evaporate within the evaporator. Since the refrigerant evaporation process occurs at a certain pressure, the corresponding saturation temperature is constant. Therefore, as the refrigerant flow rate increases, more heat is absorbed per unit time, and the refrigerant vapor temperature at the evaporator outlet approaches the saturation temperature, thereby reducing the evaporator's superheat.

[0165] In this embodiment, for the personnel flow scenario, the parameters of the compressor or indoor unit expansion valve can be adjusted according to the size of the change rate of the number of people, thereby quickly responding to the load changes caused by the change of personnel and effectively improving the comfort of indoor personnel.
