Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of air conditioner control, and particularly relate to an air conditioner multi-connected system control method and an air conditioner multi-connected system. BACKGROUND

[0002] An air conditioner multi-connected system contains multiple temperature regulation devices, and can achieve flexible and fine control for different temperature regulation preparations, and is therefore widely used in scenarios requiring independent temperature control of multiple temperature regulation areas and diversified operation time and load demand. Efficient operation of the air conditioner multi-connected system relies on automatic control, and automatic start of the air conditioner multi-connected system is an important part of automatic control.

[0003] In related technologies, a fixed start time (i.e., a fixed start time is set) is used to control the start time of the air conditioner multi-connected system, so as to achieve automatic start of the temperature regulation preparation in the air conditioner multi-connected system.

[0004] However, due to the difference in parameters of different temperature regulation areas, the temperature regulation requirements of different temperature regulation areas are different, and therefore it is difficult to accurately control the temperature regulation devices of each temperature regulation area using a unified start time. SUMMARY

[0005] Embodiments of the present application provide an air conditioner multi-connected system control method and an air conditioner multi-connected system to accurately control the temperature regulation devices of different temperature regulation areas.

[0006] In a first aspect, embodiments of the present application provide a first air conditioner multi-connected system control method, which comprises: For any temperature regulation area, obtain parameter values corresponding to a plurality of collected information respectively; wherein the plurality of collected information includes part or all of the people flow information, at least one environmental information, and building information of the temperature regulation area; each collected information is associated with a collection item; Based on a target weight coefficient, the obtained plurality of parameter values are weighted and summed to obtain a target evaluation value corresponding to the temperature regulation area; wherein the target evaluation value is used to evaluate the temperature regulation requirement of the temperature regulation area, the target weight coefficient contains weight coefficients corresponding to the plurality of collected information respectively, and the target weight coefficient is obtained based on a runtime period; Determine the comparison result of the target evaluation value and a start threshold value, and when the comparison result indicates that the target evaluation value reaches the start threshold value, determine to start the temperature regulation device corresponding to the temperature regulation area; When the comparison result indicates that the target evaluation value is less than the start threshold value, determine not to start the temperature regulation device corresponding to the temperature regulation area.

[0007] The above scheme, for each temperature regulation area, obtains a plurality of collection information of the temperature regulation area, and then determines the parameter value of each collection information after quantization (each parameter value represents the temperature regulation demand reflected by the corresponding collection information); then, the target evaluation value of the temperature regulation area is obtained by weighting and summing the plurality of parameter values obtained in combination with the target weight coefficient corresponding to the running period. Since the target evaluation value is a comprehensive evaluation of the plurality of collection information of the temperature regulation area and the running period, the target evaluation value can accurately describe the temperature regulation demand of the temperature regulation area. Further, the target evaluation value is compared with the start-up threshold. If the target evaluation value reaches the start-up threshold, it means that the temperature regulation demand of the temperature regulation area is large, and therefore the temperature regulation device corresponding to the temperature regulation area is determined to be started. Conversely, if the target evaluation value is less than the start-up threshold, it means that the temperature regulation demand of the temperature regulation area is small, and therefore the temperature regulation device corresponding to the temperature regulation area is determined not to be started. The directional start-up control of the temperature regulation device in different temperature regulation areas is realized, which is more in line with the temperature regulation demand of each temperature regulation area compared with the unified start-up of all temperature regulation devices of the air conditioning multi-inverter system.

[0008] In some optional embodiments, each collection item corresponds to a plurality of preset intervals; obtaining a plurality of collection information each corresponding to a parameter value, includes: For each collection item, a preset interval matching the collection information of the collection item is selected from the corresponding plurality of preset intervals; The preset value corresponding to the selected preset interval is taken as the parameter value corresponding to the collection information.

[0009] The above scheme sets a plurality of preset intervals and their corresponding preset values for each collection item. Thus, by matching the collection information of each collection item with the corresponding plurality of preset intervals, the preset value corresponding to the matched preset interval can be taken as the parameter value corresponding to the collection information, so as to accurately determine the parameter value of each collection information.

[0010] In some optional embodiments, when the plurality of collection information includes the building information, and the building information includes a plurality of building sub-information, the parameter value corresponding to the building information is obtained by the following way: Respectively obtaining a plurality of sub-parameter values each corresponding to the plurality of building sub-information; From the obtained plurality of sub-parameter values, the largest sub-parameter value is selected as the parameter value corresponding to the building information.

[0011] The above scheme, when the building information comprises a plurality of building sub-information, respectively obtains the sub-parameter values corresponding to the plurality of building sub-information respectively, since the maximum sub-parameter value reflects the temperature regulation demand under the main influence of the building information, and the maximum sub-parameter value is taken as the parameter value corresponding to the building information.

[0012] In some optional embodiments, each building sub-information is associated with a sub-collection item, and each sub-collection item corresponds to a plurality of preset intervals; respectively obtaining the sub-parameter values corresponding to the plurality of building sub-information respectively comprises: For each sub-collection item, respectively performing: selecting a preset interval matching the building sub-information of the sub-collection item from the corresponding plurality of preset intervals; Taking the preset value corresponding to the selected preset interval as the parameter value corresponding to the building sub-information.

[0013] The above scheme sets a plurality of preset intervals and their corresponding preset values for each sub-collection item, so that by matching the building sub-information of each sub-collection item with the corresponding plurality of preset intervals, the preset value corresponding to the matched preset interval can be taken as the parameter value corresponding to the building sub-information, thereby accurately determining the parameter value of each building sub-information.

[0014] In some optional embodiments, the target weight coefficient is obtained by: From a plurality of preset weight coefficients, selecting a preset weight coefficient associated with the running time period as the target weight coefficient; wherein each preset weight coefficient is associated with a time period.

[0015] The above scheme sets the preset weight coefficients associated with different time periods respectively, and according to the current running time period, the target weight coefficient suitable for the current running condition can be selected from the preset weight coefficients.

[0016] In some optional embodiments, if the temperature regulation area is provided with a plurality of temperature regulation devices, after determining to start the temperature regulation device corresponding to the temperature regulation area, the method further comprises: Starting the temperature regulation device corresponding to the temperature regulation area, and monitoring the environmental information corresponding to the temperature regulation area; When the monitored environmental information meets the shutdown environmental condition, determining whether to shut down the running temperature regulation device based on the number of running temperature regulation devices of the temperature regulation area and in combination with the target limit value.

[0017] According to the scheme, after the temperature adjusting device corresponding to the temperature adjusting area is turned on, whether to turn off the temperature adjusting device corresponding to the temperature adjusting area is determined according to the number of the temperature adjusting devices running in the temperature adjusting area and the target limit value when the monitored environmental information meets the shutdown environmental condition, so that the targeted shutdown control of the temperature adjusting devices in different temperature adjusting areas is realized, and compared with the unified shutdown of all temperature adjusting devices of the air conditioning multi-split system, the temperature adjusting requirement of each temperature adjusting area is more in line with the temperature adjusting requirement of each temperature adjusting area.

[0018] In some optional embodiments, the target limit value is obtained by the following method: An initial limit value is determined based on the total number of the temperature adjusting devices corresponding to the temperature adjusting area and a preset proportion; The initial limit value is adjusted based on the area type of the temperature adjusting area to obtain the target limit value; Alternatively, The target limit value is obtained based on the sub-area types corresponding to the plurality of sub-areas included in the temperature adjusting area and the number of the temperature adjusting devices corresponding to the plurality of sub-areas.

[0019] According to the total number of the temperature adjusting devices corresponding to the temperature adjusting area and the preset proportion, the initial limit value of the preset proportion is obtained, and then the initial limit value is adjusted based on the area type of the temperature adjusting area to obtain the target limit value under the double restrictions of the preset proportion and the area type, so that the target limit value is not only reasonable in proportion, but also meets the temperature adjusting requirement of the temperature adjusting area; alternatively, the target limit value meeting the temperature adjusting requirement of the temperature adjusting area is accurately obtained based on the sub-area types corresponding to the plurality of sub-areas included in the temperature adjusting area and the number of the temperature adjusting devices corresponding to the plurality of sub-areas.

[0021] The above scheme, if the number of running temperature adjusting devices is greater than the target limit value, indicates that the temperature adjusting region currently runs more temperature adjusting devices, and therefore at least one temperature adjusting device (target temperature adjusting device) needs to be selected from the running temperature adjusting devices to be closed; otherwise, if the number of running temperature adjusting devices is not greater than the target limit value, indicates that the temperature adjusting region currently runs temperature adjusting devices within the constraint range of the target limit value, and therefore it is determined that the temperature adjusting devices corresponding to the temperature adjusting region are not closed.

[0022] In some optional embodiments, the target temperature adjusting device is selected by: The difference between the number of running temperature adjusting devices and the target limit value is taken as the number of closed devices. According to the priority of each sub-region included in the temperature adjusting region, the closed number of temperature adjusting devices are selected from at least one sub-region as the target temperature adjusting device.

[0023] The above scheme, since the difference between the number of running temperature adjusting devices and the target limit value is the minimum number of temperature adjusting devices that need to be closed to meet the constraint of the target limit value, the difference is taken as the number of closed devices, and according to the priority of each sub-region included in the temperature adjusting region, the closed number of temperature adjusting devices are selected from at least one sub-region as the target temperature adjusting device, so that the temperature adjusting devices in the sub-region with lower temperature adjusting demand are preferentially closed.

For those skilled in the art, the specific meaning of the above-mentioned term in the present application can be understood according to the specific circumstances.

[0040] The air conditioning multi-connected system includes multiple temperature regulation devices, and can realize flexible and fine control for different temperature regulation preparations, and is widely used in scenes requiring independent temperature control of multiple temperature regulation areas and diversified operation time and load demand. The efficient operation of the air conditioning multi-connected system depends on automatic control, and the automatic start of the air conditioning multi-connected system is an important part of the automatic control.

[0041] In the related art, the start time of the air conditioning multi-connected system is controlled by timing (i.e., a fixed start time is set), so as to realize the automatic start of the temperature regulation preparation in the air conditioning multi-connected system.

[0042] However, due to the difference in parameters of different temperature regulation areas, the temperature regulation requirements of different temperature regulation areas are different, so it is difficult to accurately control the start of the temperature regulation devices in each temperature regulation area using a unified start time.

[0043] Therefore, the embodiments of the present application propose an air conditioning multi-connected system control method and an air conditioning multi-connected system to save the power consumption of the air conditioning multi-connected system.

[0044] Figure 1 An air conditioning multi-connected system is provided for the embodiments, which includes multiple temperature regulation devices distributed in multiple temperature regulation areas. Referring to Figure 1 As shown in the figure, the temperature regulation area 1 is provided with the temperature regulation device 11, the temperature regulation device 12 and the temperature regulation device 13; the temperature regulation area 2 is provided with the temperature regulation device 21 and the temperature regulation device 22; and the temperature regulation area 3 is provided with the temperature regulation device 31, the temperature regulation device 32 and the temperature regulation device 33.

[0045] Figure 1 Taking three temperature regulation areas as an example, in the implementation, the air conditioning multi-connected system can be associated with more or less temperature regulation areas, and each temperature regulation area can be provided with more or less temperature regulation devices.

[0046] The embodiments of the present application independently direct the start control of the temperature regulation devices in different temperature regulation areas.

[0047] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below in combination with the drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments.

[0048] Figure 2 A flowchart of a first air conditioner multi-connected system control method provided by an embodiment of the present application is shown in FIG. 1, which includes the following steps: Figure 2 Step S201: Obtain parameter values corresponding to a plurality of collection information respectively for any temperature regulation area; wherein the plurality of collection information includes part or all of the people flow information, at least one environmental information and building information of the temperature regulation area; each collection information is associated with a collection item.

[0049] In the embodiment of the present application, independent temperature regulation equipment control is performed for each temperature regulation area, and based on this, the collection information corresponding to each collection item of each temperature regulation area needs to be obtained respectively. Since the collection information is only the collected parameters and cannot directly reflect the temperature regulation demand, the collection information needs to be quantified to obtain parameter values, and each parameter value can represent the temperature regulation demand reflected by the corresponding collection information.

[0050] In the implementation, the plurality of collection information includes part or all of the people flow information, environmental information and building information of the temperature regulation area. Since more than one environmental factor can affect the temperature regulation demand of the temperature regulation area, the environmental information can have one or more items. For example, the indoor temperature can be used as an item of environmental information, and the outdoor temperature can be used as another item of environmental information.

[0051] The embodiment of the present application does not limit the obtaining method of each of the plurality of collection information, which will be described below with several specific examples: For the people flow information, a person re-identification (ReID) camera can be used to track the people flow of the temperature regulation area in real time to obtain the people flow information; or an infrared thermal imaging sensor can be used to estimate the people flow based on the number of heat sources to obtain the people flow information.

[0052] For the indoor temperature, a temperature sensor installed in the temperature regulation area can be used to collect the indoor temperature of the temperature regulation area; or the return air temperature of the temperature regulation equipment can be used as the indoor temperature of the temperature regulation area.

[0053] For the outdoor temperature, a temperature sensor installed outdoors can be used to collect the outdoor temperature; or the temperature of the region where the temperature regulation area is located can be obtained through networking, and the temperature can be used as the outdoor temperature. ​

[0054] For building information, building information (BIM) map is constructed, and building information of the temperature regulation area is obtained from the BIM map.

[0055] Step S202: Based on the target weight coefficient, the obtained multiple parameter values are weighted and summed to obtain a target evaluation value corresponding to the temperature regulation area; wherein the target evaluation value is used to evaluate the temperature regulation requirement of the temperature regulation area, the target weight coefficient contains the weight coefficient corresponding to each of the multiple collection information, and the target weight coefficient is obtained based on the runtime period.

[0056] In the embodiment of the application, the target weight coefficient corresponding to the runtime period is combined, the target weight coefficient contains the weight coefficient corresponding to each of the multiple collection information, and the target evaluation value of the temperature regulation area is obtained by weighting and summing the obtained multiple parameter values based on the target weight coefficient. Since the target evaluation value is comprehensive of the multiple collection information of the temperature regulation area and the runtime period, the temperature regulation requirement of the temperature regulation area can be accurately described.

[0057] The target evaluation value of the temperature regulation area i is represented as: Pi= ; wherein A ij is the collection parameter of the jth collection item of the temperature regulation area i, W j is the weight coefficient of the jth collection item in the target weight coefficient, and N is the total number of collection items.

[0058] Step S203: Based on the comparison result of the target evaluation value and the start-up threshold, it is determined whether to start the temperature regulation device corresponding to the temperature regulation area.

[0059] By comparing the target evaluation value with the start-up threshold, it can be accurately determined whether to start the temperature regulation device of the temperature regulation area.

[0060] The above scheme obtains, for each temperature regulation region, a plurality of collection information of the temperature regulation region, and then determines parameter values after quantization of each collection information (each parameter value represents the temperature regulation demand reflected by the corresponding collection information); and then, in combination with a target weight coefficient corresponding to a running period, the plurality of parameter values obtained are weighted and summed to obtain a target evaluation value of the temperature regulation region. Since the target evaluation value is comprehensive of the plurality of collection information of the temperature regulation region and the running period, the temperature regulation demand of the temperature regulation region can be accurately described. By comparing the target evaluation value with the start-up threshold, whether to start up the temperature regulation device of the temperature regulation region can be accurately determined, thereby realizing directional start-up control of the temperature regulation device in different temperature regulation regions, and being more in line with the temperature regulation demand of each temperature regulation region compared with starting up all temperature regulation devices of the air conditioning multi-in-one system.

[0061] Figure 3 A flowchart of a second air conditioning multi-in-one system control method provided by the embodiment of the present application is shown in FIG. 2, which includes the following steps: Figure 3 Step S301: For any temperature regulation region, obtain a plurality of parameter values corresponding to a plurality of collection information respectively; wherein the plurality of collection information includes part or all of the passenger flow information, at least one environmental information and building information of the temperature regulation region; each collection information is associated with one collection item.

[0062] Step S302: Based on a target weight coefficient, the plurality of parameter values obtained are weighted and summed to obtain a target evaluation value corresponding to the temperature regulation region; wherein the target evaluation value is used to evaluate the temperature regulation demand of the temperature regulation region, the target weight coefficient contains weight coefficients corresponding to the plurality of collection information respectively, and the target weight coefficient is obtained based on a running period.

[0063] The specific implementation of steps S301-S302 can refer to other embodiments, which will not be described here.

[0064] Step S303: Determine whether the target evaluation value reaches a start-up threshold.

[0065] In the embodiment of the present application, the start-up threshold representing the temperature regulation demand demarcation line is set. By comparing the target evaluation value with the start-up threshold, if the target evaluation value reaches the start-up threshold, it means that the temperature regulation demand of the temperature regulation region is large, and therefore the temperature regulation device corresponding to the temperature regulation region is determined to be started up, i.e., step S304 is executed; otherwise, if the target evaluation value is less than the start-up threshold, it means that the temperature regulation demand of the temperature regulation region is small, and therefore the temperature regulation device corresponding to the temperature regulation region is determined not to be started up, i.e., step S305 is executed.

[0066] ​Step S304: determining to start the temperature adjusting device corresponding to the temperature adjusting area.

[0067] Step S305: determining not to start the temperature adjusting device corresponding to the temperature adjusting area.

[0068] The above scheme, if the target evaluation value reaches the start threshold, it means that the temperature adjusting demand of the temperature adjusting area is large, therefore, it is determined to start the temperature adjusting device corresponding to the temperature adjusting area; on the contrary, if the target evaluation value is less than the start threshold, it means that the temperature adjusting demand of the temperature adjusting area is small, therefore, it is determined not to start the temperature adjusting device corresponding to the temperature adjusting area.

[0069] Figure 4 The third air conditioner multi-split system control method provided by the embodiment of the present application is shown in the flowchart as shown in Figure 4 The steps include: Step S401: for any temperature adjusting area, for each collection item, respectively performing: selecting a preset interval matching the collection information of the collection item from a plurality of preset intervals; taking the preset value corresponding to the selected preset interval as the parameter value corresponding to the collection information.

[0070] The embodiment of the present application sets a plurality of preset intervals and their corresponding preset values for each collection item, so that by matching the collection information of each collection item with the corresponding plurality of preset intervals, the preset value corresponding to the matched preset interval can be used as the parameter value corresponding to the collection information.

[0071] In implementation, when a collection item corresponds to a sub-collection item, a plurality of preset intervals and their corresponding preset values corresponding to each sub-collection item can be respectively set.

[0072] The embodiment of the present application does not limit the plurality of preset intervals of the plurality of collection information and the preset values of each preset interval, and the following will be described with several specific examples: For the people flow collection item, please refer to Table 1 shown as follows: Table 1

[0073] In implementation, the larger the people flow is, the larger the temperature adjusting demand is, therefore, as the preset interval corresponding to the people flow collection item increases, the preset value also increases. The above Table 1 takes three preset intervals corresponding to the people flow collection item as an example, in implementation, the people flow collection item can be set with more or less preset intervals.

[0074] For the indoor temperature collection item, since the indoor temperature varies significantly in different seasons, a plurality of preset intervals can be set for summer and winter respectively, please refer to Table 2 shown as follows: Table 2

[0075] In implementation, in summer, the higher the indoor temperature, the greater the temperature regulation demand (cooling demand), therefore, as the preset interval corresponding to the indoor temperature collection item increases, the preset value also increases. The above table 2 takes 4 preset intervals corresponding to the indoor temperature collection item in summer as an example, in implementation, more or less preset intervals can be set.

[0076] In winter, the higher the indoor temperature, the smaller the temperature regulation demand (heating demand), therefore, as the preset interval corresponding to the indoor temperature collection item increases, the preset value decreases. The above table 2 takes 4 preset intervals corresponding to the indoor temperature collection item in winter as an example, in implementation, more or less preset intervals can be set.

[0077] For the outdoor temperature collection item, since the outdoor temperature in different seasons is significantly different, therefore, for summer and winter, multiple preset intervals can be set respectively, which can be referred to in table 3: Table 3

[0078] In implementation, in summer, the higher the outdoor temperature, the greater the temperature regulation demand (cooling demand), therefore, as the preset interval corresponding to the outdoor temperature collection item increases, the preset value also increases. The above table 3 takes 4 preset intervals corresponding to the outdoor temperature collection item in summer as an example, in implementation, more or less preset intervals can be set.

[0079] In winter, the higher the outdoor temperature, the smaller the temperature regulation demand (heating demand), therefore, as the preset interval corresponding to the outdoor temperature collection item increases, the preset value decreases. The above table 3 takes 4 preset intervals corresponding to the outdoor temperature collection item in winter as an example, in implementation, more or less preset intervals can be set.

[0080] For the building collection item, since the building characteristics have multiple dimensions, such as floor, orientation, etc., therefore, the building characteristics of each dimension can be used as a building information sub-collection item, therefore, for each building information sub-collection item, multiple preset intervals can be set respectively. Taking the floor sub-collection item as an example, which can be referred to in table 4: Table 4

[0081] In implementation, the top layer is a high-heat-dissipation and easy-to-accumulate-heat area, for example, a roof directly exposed to summer sunlight, the heat load is significantly higher than that of the middle layer; in winter, the roof has a large contact area with cold air, and the heat dissipation is significantly higher than that of the middle layer, therefore, the temperature regulation requirement of the top layer is greater than that of the middle layer, and the preset value of the top layer is higher than other preset values. The middle layer is moderately affected by the external environment, and the preset value of the middle layer is moderate. The first floor is frequently accessed by people due to the door, and the opening and closing of the door causes serious cold / heat loss, therefore, the temperature regulation requirement of the first floor is greater than that of other floors, and the preset value of the first floor is the highest. The underground is less affected by the change of external air temperature, has low heat load in summer, and has less heat dissipation in winter, therefore, a smaller preset value can be set.

[0082] For example, referring to Table 5: Table 5

[0083] In implementation, in the afternoon of summer, the westward heat load is extremely large due to the compensation effect of westward sun exposure, therefore, the corresponding preset value is larger than the preset values of other orientations. In the morning of summer, the eastward heat load is large due to the compensation effect of morning sun exposure, therefore, the corresponding preset value is larger. The westward and eastward heat loads are small in other seasons / periods due to less influence of light, and the corresponding preset values are small. In winter, the southward orientation benefits from sunlight during heating, and a smaller preset value can be set. In the middle of summer, the southward heat load is large due to strong light, therefore, the corresponding preset value is large. The southward heat load is small in other periods of summer due to less influence of light, and the corresponding preset value is small. The northward heat load is the most stable throughout the year, and almost no additional compensation is needed, and the corresponding preset value is small.

[0084] The above Table 4 and Table 5 take floor sub-collection items and orientation sub-collection items as examples, in implementation, the building collection items can include other sub-collection items, which are not limited in the embodiments of the present application.

[0085] Step S402: based on a target weight coefficient, performing weighted summation on the obtained multiple parameter values to obtain a target evaluation value corresponding to the temperature regulation area; wherein the target evaluation value is used to evaluate the temperature regulation requirement of the temperature regulation area, the target weight coefficient includes weight coefficients corresponding to the multiple collection information respectively, and the target weight coefficient is obtained based on a running period.

[0086] Step S403: based on a comparison result of the target evaluation value and a start-up threshold, determining whether to start up a temperature regulation device corresponding to the temperature regulation area.

[0087] The specific implementation of steps S402-S403 can refer to other embodiments, which will not be described here.

[0088] The above scheme sets multiple preset intervals and corresponding preset values for each collection item, so that the preset value corresponding to the matched preset interval of each collection item can be used as the parameter value corresponding to the collection information, thereby accurately determining the parameter value of each collection information.

[0089] As described above, the building collection item can include multiple sub-collection items, and the building information includes multiple building sub-information. The parameter value corresponding to the building information can be obtained by, but not limited to, the following manner: Respectively obtaining the sub-parameter value corresponding to each of the multiple building sub-information; From the obtained multiple sub-parameter values, selecting the maximum sub-parameter value as the parameter value corresponding to the building information.

[0090] When the building information includes multiple building sub-information, the sub-parameter value corresponding to each of the multiple building sub-information is respectively obtained. Since the maximum sub-parameter value reflects the temperature regulation demand under the main influence of the building information, the maximum sub-parameter value is used as the parameter value corresponding to the building information.

[0091] In some optional embodiments, each sub-collection item corresponds to multiple preset intervals. The sub-parameter value corresponding to each of the multiple building sub-information can be obtained by, but not limited to, the following manner: For each sub-collection item, the following is performed: from the corresponding multiple preset intervals, selecting a preset interval matched with the building sub-information of the sub-collection item; The preset value corresponding to the selected preset interval is used as the parameter value corresponding to the building sub-information.

[0092] In the embodiments of the present application, multiple preset intervals and corresponding preset values are set for each sub-collection item. By matching the building sub-information of each sub-collection item with the corresponding multiple preset intervals, the preset value corresponding to the matched preset interval can be used as the parameter value corresponding to the building sub-information.

[0093] Figure 5 A flowchart of a fourth air conditioner multi-connected system control method provided by the embodiments of the present application is shown in FIG. 4, which includes the following steps: Figure 5 As shown in FIG. 4, the method includes the following steps: Step S501: obtaining the parameter value corresponding to each of the multiple collection information for any temperature regulation area; wherein the multiple collection information includes part or all of the people flow information, at least one environmental information, and building information of the temperature regulation area; each collection information is associated with a collection item.

[0094] The specific implementation of step S501 can refer to other embodiments, which will not be described here.

[0095] Step S502: selecting, from the plurality of preset weight coefficients, a preset weight coefficient associated with the running time period as a target weight coefficient; wherein each preset weight coefficient is associated with a time period.

[0096] Since the influence of different collection items is different at different time periods, by setting the respective preset weight coefficients corresponding to different time periods, a preset weight coefficient associated with the current running time period can be selected from the preset weight coefficients as the target weight coefficient.

[0097] The division of time periods and the corresponding specific preset weight coefficients are not limited in the embodiments of the present application. Taking the people flow collection item, the indoor temperature collection item, the outdoor temperature collection item, and the building collection item as examples, the preset weight coefficients include W1-W4, W1 is the weight coefficient of the people flow collection item, W2 is the weight coefficient of the indoor temperature collection item, W3 is the weight coefficient of the outdoor temperature collection item, and W4 is the weight coefficient of the building collection item. The preset weight coefficients can be referred to Table 6: Table 6

[0098] In the implementation, for the peak period with a large number of people, temperature regulation needs to be quickly realized and maintained, therefore, W1 is relatively large; for the idle period with a small number of people, the influence of the cold and heat load of the building (such as the west sun residual heat) is increased, therefore, the proportion of W4 is increased. The above Table 6 is only an exemplary description of the preset weight coefficients, and in the implementation, more time periods can be divided to realize more precise preset weight coefficient settings.

[0099] Step S503: based on the target weight coefficient, performing weighted summation on the obtained plurality of parameter values to obtain a target evaluation value corresponding to the temperature regulation area; wherein the target evaluation value is used to evaluate the temperature regulation demand of the temperature regulation area, the target weight coefficient includes the weight coefficients corresponding to the plurality of collection information respectively, and the target weight coefficient is obtained based on the running time period.

[0100] Step S504: determining whether to start the temperature regulation device corresponding to the temperature regulation area based on the comparison result of the target evaluation value and the start threshold.

[0101] The specific implementation modes of steps S503-S504 can refer to other embodiments, which will not be described herein.

[0102] The above scheme sets the respective preset weight coefficients associated with different time periods, and according to the current running time period, a target weight coefficient suitable for the current running condition can be selected from the preset weight coefficients.

[0103] The following describes the start control with a specific example: The temperature regulation area is a top floor west-facing conference room, the time is 14:00 in summer (peak period), according to the preset weight coefficients shown in Table 6, it is determined to select the preset weight coefficient corresponding to the peak period: W1-0.25, W2-0.35, W3-0.25, W4-0.15.

[0104] The passenger flow information is 5 people, according to the preset interval of the passenger flow collection item shown in Table 1, it is known that it matches the third preset interval, and the parameter value is 0.2; The indoor temperature information is 29℃, according to the preset interval of the indoor temperature collection item shown in Table 2, it is known that it matches the first preset interval, and the parameter value is 1; The outdoor temperature information is 35℃, according to the preset interval of the outdoor temperature collection item shown in Table 3, it is known that it matches the first preset interval, and the parameter value is 1; The floor is the top floor, according to the preset interval of the floor sub-collection item shown in Table 4, it is known that it matches the first preset interval, and the parameter value is 0.7; The orientation is westward, according to the preset interval of the orientation sub-collection item shown in Table 5, it is known that it matches the first preset interval, and the parameter value is 0.7; The parameter value is finally selected as 0.7 by combining the floor and the orientation.

[0105] The evaluation value = 0.25 0.2+0.35 1+0.25 1+0.15 0.7=0.755, the starting threshold is 0.7, therefore, it is determined to start the temperature regulation equipment corresponding to the temperature regulation area.

[0106] Figure 6 The flowchart of the fifth air conditioner multi-outlet system control method provided by the embodiment of the application is shown in FIG. 6, which includes the following steps: Figure 6 Step S601: obtaining the parameter values corresponding to the plurality of collection information for any temperature regulation area; wherein the plurality of collection information includes part or all of the passenger flow information, at least one environmental information and building information of the temperature regulation area; each collection information is associated with a collection item.

[0107] Step S602: based on the target weight coefficient, the plurality of parameter values obtained are weighted and summed to obtain the target evaluation value corresponding to the temperature regulation area; wherein the target evaluation value is used to evaluate the temperature regulation demand of the temperature regulation area, the target weight coefficient contains the weight coefficient corresponding to the plurality of collection information, and the target weight coefficient is obtained based on the running period.

[0108] ​Step S603: When the comparison result indicates that the target evaluation value reaches the start-up threshold, it is determined to start the temperature adjusting device corresponding to the temperature adjusting area.

[0109] The specific implementation of steps S601-S603 can refer to other embodiments, which will not be described here.

[0110] Step S604: Start the temperature adjusting device corresponding to the temperature adjusting area, and monitor the environmental information corresponding to the temperature adjusting area.

[0111] In the implementation, after starting the temperature adjusting device, the environmental information corresponding to the temperature adjusting area is monitored, and the shutdown control of the temperature adjusting device is realized according to the monitored environmental information.

[0112] The monitoring interval (that is, the monitoring period) is not specifically limited in the embodiments of the present application, and can be set according to the specific application scene, such as monitoring the environmental information every 1 min, monitoring the environmental information every 2 min, or monitoring the environmental information every 10 s, etc.

[0113] The environmental information is not specifically limited in the embodiments of the present application, but the environmental information needs to match the shutdown environmental condition. For example, if the shutdown environmental condition includes the temperature condition, the environmental information includes the temperature information; if the shutdown environmental condition includes the humidity condition, the environmental information includes the humidity information.

[0114] Step S605: When the monitored environmental information meets the shutdown environmental condition, it is determined whether to shut down the running temperature adjusting device based on the number of temperature adjusting devices running in the temperature adjusting area and in combination with the target limit value.

[0115] In the implementation, by setting the shutdown environmental condition, it can be determined in real time whether the monitored environmental information meets the shutdown environmental condition. When the shutdown environmental condition is met, it can be further determined whether to shut down the temperature adjusting device corresponding to the temperature adjusting area according to the number of temperature adjusting devices running in the temperature adjusting area and the target limit value (the target limit value is the number of temperature adjusting devices matched with the temperature adjusting area), so as to realize the directional shutdown control of the temperature adjusting device in different temperature adjusting areas.

[0116] The shutdown environmental condition is not specifically limited in the embodiments of the present application. Since the climate in different regions has significant differences, different shutdown environmental conditions can be set for different regions.

[0117] The following is described with a specific example: For region 1 and region 2, the shutdown environmental condition includes temperature condition and humidity condition; the temperature condition includes indoor temperature condition and outdoor temperature condition; the humidity condition of region 1 includes indoor humidity condition and outdoor humidity condition, and the humidity condition of region 2 only includes indoor humidity condition.

[0118] The indoor temperature condition is that the temperature is stable in a first temperature range [T1~T2], and T1 and T2 of region 1 and region 2 can be the same or different. For region 1, T1 is 24℃ and T2 is 26℃; for region 2, T1 is 25℃ and T2 is 27℃.

[0119] Here, the temperature stable in [T1~T2] means that not only one or a few collected indoor temperature information is in [T1~T2], but also a first preset number (such as 50) of continuous indoor temperature information is in [T1~T2], or the average value of indoor temperature information in a first preset time length (such as 10min) is in [T1~T2]. This reduces the occurrence of false triggering of the shutdown environmental condition caused by sudden change of indoor temperature or error of collected indoor temperature (such as temperature sensor failure).

[0120] The outdoor temperature condition is that the temperature is stable in a second temperature range [T3~T4], and T3 and T4 of region 1 and region 2 can be the same or different. For region 1, T3 is 24℃ and T4 is 28℃; for region 2, T3 is 25℃ and T4 is 28℃.

[0121] Here, the temperature stable in [T3~T4] means that not only one or a few collected outdoor temperature information is in [T3~T4], but also a second preset number (such as 100) of continuous outdoor temperature information is in [T3~T4], or the average value of outdoor temperature information in a second preset time length (such as 30min) is in [T3~T4]. This reduces the occurrence of false triggering of the shutdown environmental condition caused by sudden change of outdoor temperature or error of collected outdoor temperature (such as temperature sensor failure).

[0122] The indoor humidity condition is that the indoor humidity is stable in a first humidity range [H1~H2], and H1 and H2 of region 1 and region 2 can be the same or different. For region 1, H1 is 0% and H2 is 65%; for region 2, H1 is 0% and H2 is 70%.

[0123] The indoor humidity is stable between [H1-H2] here, which means that not only one or a few collected indoor humidity information is between [H1-H2], but also a third preset number (such as 10) of continuous indoor humidity information is between [H1-H2], or the average value of indoor humidity information within a third preset time (such as 5 minutes) is between [H1-H2]. This reduces the occurrence of false triggering of the shutdown environmental condition caused by sudden changes in indoor humidity or incorrect collection of indoor humidity (such as humidity sensor failure).

[0124] The outdoor humidity condition is that the outdoor humidity is stable between [H3-H4], and there is no outdoor humidity condition in region 2. For region 1, H3 is 0% and H4 is 75%.

[0125] The outdoor humidity is stable between [H3-H4] here, which means that not only one or a few collected outdoor humidity information is between [H3-H4], but also a fourth preset number (such as 20) of continuous outdoor humidity information is between [H3-H4], or the average value of outdoor humidity information within a fourth preset time (such as 10 minutes) is between [H3-H4]. This reduces the occurrence of false triggering of the shutdown environmental condition caused by sudden changes in outdoor humidity or incorrect collection of outdoor humidity (such as humidity sensor failure).

[0126] The above shutdown environmental condition is only an example, and the embodiments of the present application are not limited thereto.

[0127] The above scheme, after starting the temperature regulation device corresponding to the temperature regulation area, monitors the environmental information corresponding to the temperature regulation area, and when the monitored environmental information meets the shutdown environmental condition, determines whether to turn off the temperature regulation device corresponding to the temperature regulation area according to the number of temperature regulation devices running in the temperature regulation area and the target limit value, thereby realizing directional shutdown control of temperature regulation devices in different temperature regulation areas. Compared with uniformly shutting down all temperature regulation devices of the air conditioning multi-split system, it is more in line with the temperature regulation needs of each temperature regulation area.

[0128] In some optional embodiments, the target limit value is obtained by: determining an initial limit value based on the total number of temperature regulation devices corresponding to the temperature regulation area and a preset proportion; adjusting the initial limit value based on the area type of the temperature regulation area to obtain the target limit value; Alternatively, obtaining the target limit value based on the area types of the plurality of sub-areas included in the temperature regulation area and the number of temperature regulation devices corresponding to each of the plurality of sub-areas.

[0129] Since the target limit is the number of temperature regulation devices matching the temperature regulation region, both the type of the temperature regulation region itself and the total number of temperature regulation devices affect the target limit.

[0130] Based on this, the embodiment of the present application obtains an initial limit value accounting for a preset proportion of the total number of temperature regulation devices according to the total number of temperature regulation devices corresponding to the temperature regulation region and the preset proportion. However, the scheduling regulation demands of different temperature regulation regions are different, and therefore, the initial limit value is further adjusted based on the region type of the temperature regulation region to obtain a target limit value under the double restrictions of the preset proportion and the region type, so that the target limit value is not only reasonable in proportion, but also meets the temperature regulation demand of the temperature regulation region.

[0131] Illustratively, the product between the total number of temperature regulation devices and the preset proportion is taken as the initial limit value; the adjustment coefficient corresponding to the region type is determined, and the product between the initial limit value and the adjustment coefficient is taken as the target limit value.

[0132] The embodiment of the present application does not specifically limit the adjustment coefficient, such as that the adjustment coefficient is greater than 1 (such as 1.2) for a region type with high scheduling regulation demand; the adjustment coefficient is 1 for a region type with general scheduling regulation demand; and the adjustment coefficient is less than 1 (such as 0.8) for a region type with low scheduling regulation demand.

[0133] In implementation, some temperature regulation regions contain sub-regions of different sub-region types (that is, the temperature regulation region is further subdivided into different sub-regions, and the sub-region types of these sub-regions are different); at this time, the target limit value meeting the temperature regulation demand of the temperature regulation region can also be accurately obtained according to the sub-region types corresponding to the multiple sub-regions contained by the temperature regulation region in combination with the number of temperature regulation devices corresponding to each of the multiple sub-regions.

[0134] Illustratively, different weights are set for different sub-region types, and the number of temperature regulation devices corresponding to each of the multiple sub-regions is weighted and summed to obtain the target limit value.

[0135] For example, the weight is 1 for a sub-region type with high scheduling regulation demand, and the weight is 0.5 for a sub-region type with general scheduling regulation demand and a sub-region type with low scheduling regulation demand.

[0136] In implementation, in order to ensure the most basic temperature regulation of the temperature regulation region, a device number lower limit (such as 1) can be set, and no matter which way is used to calculate the target limit value, the target limit value cannot be less than the device number lower limit (when the calculation result of the above target limit value is less than the device number lower limit, the calculation result is not selected, but the device number lower limit is selected as the target limit value), so that it can be ensured that the temperature regulation region has at least the device number lower limit of temperature regulation devices running.

[0137] The above scheme obtains an initial limit value of the preset proportion according to the total number of the temperature adjusting devices corresponding to the temperature adjusting area and the preset proportion, and then adjusts the initial limit value based on the area type of the temperature adjusting area to obtain a target limit value under the double restrictions of the preset proportion and the area type, so that the target limit value is not only reasonable in proportion, but also meets the temperature adjusting demand of the temperature adjusting area; or, the target limit value meeting the temperature adjusting demand of the temperature adjusting area is accurately obtained according to the respective sub-area types of the multiple sub-areas included in the temperature adjusting area and in combination with the number of the temperature adjusting devices corresponding to the respective sub-areas.

[0138] In some optional embodiments, whether to close the running temperature adjusting devices is determined based on the number of the running temperature adjusting devices and in combination with the target limit value, including: When the number of the running temperature adjusting devices is greater than the target limit value, it is determined to close the temperature adjusting devices corresponding to the temperature adjusting area, and to select target temperature adjusting devices from the running temperature adjusting devices to close; When the number of the running temperature adjusting devices is not greater than the target limit value, it is determined not to close the running temperature adjusting devices.

[0139] In the implementation, if the number of the running temperature adjusting devices is greater than the target limit value, it indicates that the temperature adjusting area currently has more running temperature adjusting devices, and therefore at least one temperature adjusting device (target temperature adjusting device) needs to be selected from the running temperature adjusting devices to close; conversely, if the number of the running temperature adjusting devices is not greater than the target limit value, it indicates that the temperature adjusting area currently has running temperature adjusting devices within the constraint range of the target limit value, and therefore it is determined not to close the running temperature adjusting devices.

[0140] In some optional embodiments, the target temperature adjusting devices are selected by the following manner: The difference between the number of the running temperature adjusting devices and the target limit value is taken as the number of the temperature adjusting devices to be closed; According to the respective priorities of the multiple sub-areas included in the temperature adjusting area, the temperature adjusting devices of the number to be closed are selected from at least one sub-area as the target temperature adjusting devices.

[0141] In the implementation, the difference between the number of the running temperature adjusting devices and the target limit value is exactly the minimum number of the temperature adjusting devices to be closed to meet the constraint of the target limit value, and therefore the difference is taken as the number of the temperature adjusting devices to be closed, and the target temperature adjusting devices of the number to be closed are selected.

[0142] The embodiments of the present application divide the temperature regulation area into multiple sub-areas, obtain sub-area types of each sub-area, and different sub-area types correspond to different priorities. For example, as the scheduling regulation demand increases, the priority decreases. In accordance with the order from high to low priority, the target temperature regulation device is preferentially selected from the sub-area with small scheduling regulation demand.

[0143] In the implementation, when a first number (the number of temperature regulation devices that need to be turned off in the one sub-area, if the one sub-area is the highest priority, the first number is the number of temperature regulation devices that need to be turned off; if the one sub-area is not the highest priority, the first number is the difference between the number of temperature regulation devices that need to be turned off and the number of temperature regulation devices that have been selected as the target temperature regulation device in the sub-area with higher priority) of temperature regulation devices is selected from the one sub-area, if the number of temperature regulation devices in the one sub-area is less than the first number, all the temperature regulation devices in the one sub-area are selected as the target temperature regulation device; and then a second number (the number of temperature regulation devices that need to be turned off after the first number of target temperature regulation devices are selected) of temperature regulation devices is selected from the next sub-area. If the number of temperature regulation devices in the one sub-area is equal to the first number, all the temperature regulation devices in the one sub-area are directly selected as the target temperature regulation device. If the number of temperature regulation devices in the one sub-area is less than the first number, the first number of temperature regulation devices in the one sub-area are selected as the target temperature regulation device.

[0144] The embodiments of the present application do not limit the specific implementation of selecting the first number of temperature regulation devices from the temperature regulation devices in the one sub-area, which is described below with several specific examples. 1. In accordance with the order from low to high COP (coefficient of performance), the first number of temperature regulation devices are selected. 2. In accordance with the order from long to short runtime, the first number of temperature regulation devices are selected. 3. In accordance with the order from far to near distance between the temperature regulation device and the core position (personnel gathering position) of the temperature regulation area, the first number of temperature regulation devices are selected.

[0145] 4. The first number of temperature regulation devices are selected by comprehensively considering multiple factors such as COP, runtime, and distance between the temperature regulation device and the core position.

[0146] In the above scheme, the difference between the number of running temperature regulation devices and the target limit value is the minimum number of temperature regulation devices that need to be turned off to meet the target limit value. Therefore, the difference is taken as the number of temperature regulation devices to be turned off, and the number of temperature regulation devices to be turned off is selected from at least one sub-area in accordance with the priority of each sub-area included in the temperature regulation area, as the target temperature regulation device. In this way, the temperature regulation device in the sub-area with low temperature regulation demand is preferentially turned off.
