Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an energy-saving control method, device, energy-saving control equipment and medium for a central air-conditioning system. Background Art

[0002] When the central air conditioner is first put into operation, in order to shorten the time for the room temperature to reach the target temperature and improve the cooling or heating efficiency, the central air conditioner often operates in a high-power mode. After the room temperature reaches the target temperature, it switches to a low-power mode.

[0003] However, due to the existence of doors or windows, the indoor space is not enclosed, and there may be cold / heat sources such as heat dissipation equipment or refrigeration equipment in the room, which may increase the time consumed by the room temperature to reach the target temperature, causing the central air conditioner to operate in high-power mode for a longer time, increasing resource waste.

[0004] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Summary of the invention

[0005] In order to reduce the time that a central air conditioner operates in a high-power operation mode, the present application provides an energy-saving control method, device, energy-saving control equipment and medium for a central air-conditioning system.

[0006] In the first aspect, the present application provides a central air conditioning system energy-saving control method, which adopts the following technical solution:

[0007] A central air conditioning system energy-saving control method, comprising:

[0008] Receiving a specific start-up instruction, wherein the specific start-up instruction represents a preset operation mode of the central air-conditioning system;

[0009] Obtain the location information of each temperature control point in the area where it is located and the energy generated per unit time, wherein the temperature control point represents a point that has an impact on the room temperature, and the area where the temperature control point is located is a preset unit area where the temperature control point is located;

[0010] For each temperature control point, according to the correspondence between the area where the temperature control point is located and the preset air outlet and the unit area, the effective air outlet corresponding to the temperature control point and the location information of the effective air outlet are obtained, wherein each effective air outlet represents the air outlet closest to the area where each temperature control point is located;

[0011] For each temperature control point, the working time of the effective air outlet is obtained according to the energy generated per unit time corresponding to the temperature control point;

[0012] For each temperature control point, based on the location information of the temperature control point in its area and the location information of the effective air outlet corresponding to the temperature control point, obtain the air outlet direction of the effective air outlet;

[0013] Based on specific startup instructions, each effective air outlet, the working duration of each effective air outlet, and the air outlet direction, operate the central air-conditioning system.

[0014] By adopting the above technical solution, after receiving specific startup instructions, obtaining the location information of each temperature control point in its area and the energy generated per unit time, the influence of each temperature control point on the room temperature can be determined; for each temperature control point, according to the area where the temperature control point is located and the preset corresponding relationship between the air outlet and the unit area, obtain the effective air outlet corresponding to the temperature control point and the location information of the effective air outlet. By taking the preset air outlet in the unit area where the temperature control point is located as the effective air outlet, the energy consumption increased due to the long distance between the air outlet and the temperature control point can be reduced; for each temperature control point, according to the energy generated per unit time corresponding to the temperature control point, the working duration required for the effective air outlet to make the room temperature in the area where the temperature control point is located reach the target temperature can be determined; for each temperature control point, based on the location information corresponding to the temperature control point in its area and the location information of the effective air outlet corresponding to the temperature control point, obtain the air outlet direction of the effective air outlet corresponding to the temperature control point. By controlling the air outlet direction of the effective air outlet, the exchange of hot and cold air in the area where the temperature control point is located can be promoted, and the change speed of the room temperature in the area where the temperature control point is located can be accelerated; finally, based on specific startup instructions, each effective air outlet, the working duration of each effective air outlet, and the air outlet direction, operate the central air-conditioning system. By promoting the exchange speed of hot and cold air in the area where the temperature control point is located, accurately control the room temperature in the area where the temperature control point is located, shorten the time consumed for the overall room temperature to reach the target temperature, improve the cooling or heating efficiency, reduce the time for the central air-conditioning system to operate in a high-power operation mode, and achieve the energy-saving control of the central air-conditioning system.

[0015] This application can be further configured in a preferred example as follows:

[0016] According to the area where the temperature control point is located and the preset corresponding relationship between the air outlet and the unit area, obtain the effective air outlet corresponding to the temperature control point and the location information of the effective air outlet, including:

[0017] For each temperature control point, determine whether the area where the temperature control point is located is a target area with multiple temperature control points;

[0018] If so, according to the preset corresponding relationship between the air outlet and the unit area, obtain the air outlet corresponding to the target area and the location information of the air outlet;

[0019] Determine the effective temperature control points of the target area according to the position information of each temperature control point in the area where it is located and the position information of the air outlet, where the effective temperature control point is the temperature control point closest to the air outlet;

[0020] Judge whether the effective temperature control point of the target area is the current temperature control point;

[0021] If so, use the air outlet of the target area and the position information of the air outlet as the effective air outlet corresponding to the temperature control point and the position information of the effective air outlet;

[0022] If not, judge whether there is any adjacent area of the target area where there is no temperature control point;

[0023] If so, obtain a number of alternative air outlets and the position information of a number of alternative air outlets according to the corresponding relationship between the air outlet and the unit area preset, where each alternative air outlet represents the air outlet corresponding to each adjacent area without a temperature control point;

[0024] Determine the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of the number of alternative air outlets.

[0025] By adopting the above technical solution, first for each temperature control point, determine whether the area where the temperature control point is located is a target area with multiple temperature control points, so as to ensure that the air outlet direction of each air outlet covers each temperature control point, and can efficiently make the room temperature reach the target temperature; if so, according to the position information of the air outlet corresponding to the target area and the position information of each temperature control point in the target area, determine the effective temperature control point to reduce the energy consumption increased due to the long distance between the air outlet and the temperature control point; if the effective temperature control point of the target area is not the current temperature control point, then judge whether there is any adjacent area of the target area where there is no temperature control point, if so, determine the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of a number of alternative air outlets, further reducing the energy consumption increased due to the long distance between the air outlet and the temperature control point.

[0026] This application can be further configured in a preferred example as:

[0027] Before determining whether the area where the temperature control point is located is a target area with multiple temperature control points for each temperature control point, it further includes:

[0028] Sort all temperature control points from largest to smallest according to the energy generated by each temperature control point per unit time to obtain the sorting of all temperature control points;

[0029] Correspondingly, for each temperature control point, determining whether the area where the temperature control point is located is a target area with multiple temperature control points includes:

[0030] According to the sorting of all temperature control points, determine in sequence whether the area where each temperature control point is located is a target area with multiple temperature control points.

[0031] By adopting the above technical solution, based on the principle that the greater the energy generated per unit time, the greater the influence degree of each temperature control point on the room temperature, the sorting of all temperature control points is obtained through the energy generated by each temperature control point per unit time. Then, based on the sorting of all temperature control points, determine the number of temperature control points in the area where each temperature control point is located in sequence. When the total number of temperature control points is greater than the total number of air outlets, there may be several temperature control points that cannot obtain effective air outlets. By first determining the effective air outlets for the temperature control points with a greater influence degree on the room temperature, the sum of the energy generated by several temperature control points that cannot obtain effective air outlets can be reduced, and the value of the work that the central air-conditioning system needs to do can be reduced, so as to increase the speed of the room temperature reaching the target temperature.

[0032] This application can be further configured in a preferred example as follows:

[0033] Before determining the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of the several alternative air outlets, it further includes:

[0034] Obtain several filtered adjacent areas according to all adjacent areas of the target area and all preset key areas, where the filtered adjacent areas represent adjacent areas that are not key areas, and the key areas are preset areas with a large flow of people;

[0035] Obtain several filtered alternative air outlets according to the corresponding relationship between the preset air outlets and the unit area and the several filtered adjacent areas;

[0036] Correspondingly, determining the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of the several alternative air outlets includes:

[0037] Determine the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of the several filtered alternative air outlets.

[0038] By adopting the above technical solution, the adjacent areas with a small flow of people in the adjacent areas are screened out to obtain several filtered adjacent areas, which can reduce the probability that the air outlets in the key areas are occupied by the temperature control points of other unit areas, resulting in a relatively low speed of the room temperature in the key areas changing to the target temperature and a poor experience for the personnel in the key areas.

[0039] This application can be further configured in a preferred example as follows:

[0040] The specific start instruction at least includes the target temperature;

[0041] For each temperature control point, obtain the working duration of the effective air outlet according to the energy generated per unit time corresponding to the temperature control point, including:

[0042] According to the corresponding relationship between the preset target temperature and power and the target temperature, obtain the power corresponding to the target temperature;

[0043] According to the energy generated per unit time corresponding to each temperature control point and the power corresponding to the target temperature, calculate the working duration of the effective air outlet.

[0044] By adopting the above technical solution, with an accurately determined method, calculate the working duration of the effective air outlet according to the energy generated per unit time corresponding to each temperature control point and the power corresponding to the target temperature, and the working duration of the effective air outlet operating at high power can be accurately controlled.

[0045] In a preferred example of the present application, it can be further configured as:

[0046] For each temperature control point, obtain the air outlet direction of the effective air outlet according to the position information of the temperature control point in the area where it is located and the position information of the effective air outlet corresponding to the temperature control point, including:

[0047] For each temperature control point, obtain the relative position between the temperature control point and the effective air outlet according to the position information of the temperature control point in the area where it is located and the position information of the effective air outlet corresponding to the temperature control point;

[0048] For each effective air outlet, obtain the air outlet direction corresponding to the relative position according to the relative position between the temperature control point and the effective air outlet and the corresponding relationship between the preset relative position and the air outlet direction.

[0049] By adopting the above technical solution, after actually obtaining the relative position between the effective air outlet and the temperature control point, accurately determine the air outlet direction according to the relative position, and can accurately control the exchange between hot and cold air in the area where the temperature control point is located, making the control of the room temperature in the area where the temperature control point is located more accurate.

[0050] In a preferred example of the present application, it can be further configured as:

[0051] The receiving of the specific start instruction includes:

[0052] Obtain the initial specific start instruction and the previous specific start instruction, where the specific start instruction at least includes the operation mode;

[0053] Judge whether the operation modes corresponding to the initial specific start instruction and the previous specific start instruction are the same;

[0054] If they are not the same, obtain a repeated confirmation instruction, and when receiving the confirmation information corresponding to the repeated confirmation instruction, obtain the specific start instruction according to the confirmation information.

[0055] By adopting the above technical solution, it is possible to determine whether the operating modes corresponding to the initial specific start instruction and the previous specific start instruction are the same, so as to determine whether the initial specific start instruction is correct or incorrect, and avoid the central air-conditioning system from operating in an incorrect operating mode.

[0070] In summary, the present application includes at least one of the following beneficial technical effects:

[0071] 1. After receiving a specific start instruction, by obtaining the position information of each temperature control point in its area and the energy generated per unit time, the influence of each temperature control point on the room temperature can be determined; for each temperature control point, according to the area where the temperature control point is located and the preset correspondence between the air outlet and the unit area, the effective air outlet corresponding to the temperature control point and the position information of the effective air outlet can be obtained. By using the preset air outlet in the unit area where the temperature control point is located as the effective air outlet, the energy consumption increased due to the long distance between the air outlet and the temperature control point can be reduced; for each temperature control point, according to the energy generated per unit time corresponding to the temperature control point, the working duration required for the effective air outlet to work can be determined so that the room temperature in the area where the temperature control point is located reaches the target temperature; for each temperature control point, according to the position information of the temperature control point in its area and the position information of the effective air outlet corresponding to the temperature control point, the air outlet direction of the effective air outlet corresponding to the temperature control point can be obtained. By controlling the air outlet direction of the effective air outlet, the exchange speed between hot and cold air in the area where the temperature control point is located can be promoted, and the change speed of the room temperature in the area where the temperature control point is located can be accelerated; finally, based on the specific start instruction, each effective air outlet, the working duration of each effective air outlet, and the air outlet direction, the central air-conditioning system is operated. By promoting the exchange speed between hot and cold air in the area where the temperature control point is located, the room temperature in the area where the temperature control point is located is accurately controlled, the time consumed for the overall room temperature to reach the target temperature is shortened, the refrigeration or heating efficiency is improved, the time for the central air-conditioning system to operate in a high-power operation mode is reduced, and the energy-saving control of the central air-conditioning system is realized;

[0072] 2. First, for each temperature control point, it is determined whether the area where the temperature control point is located is a target area with multiple temperature control points, so as to ensure that each temperature control point is covered by the air outlet direction of the air outlet, and the room temperature can reach the target temperature efficiently; if so, according to the position information of the air outlet corresponding to the target area and the position information of each temperature control point in the target area in its area, the effective temperature control points are determined to reduce the energy consumption increased due to the long distance between the air outlet and the temperature control point; if the effective temperature control point of the target area is not the current temperature control point, it is judged whether there is any adjacent area in the target area without a temperature control point. If so, according to the position information of the current temperature control point and the position information of several alternative air outlets, the effective air outlet of the current temperature control point is determined, further reducing the energy consumption increased due to the long distance between the air outlet and the temperature control point.

After reading this specification, those skilled in the art can make modifications without creative contributions to this embodiment as needed, but as long as they are within the scope of the present application, they are protected by the patent law.

Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0080] Generally, the application places of central air conditioners are public places such as shopping malls and office buildings. In public places, to save energy consumption, central air conditioners often operate in a high-power operation mode. After the room temperature reaches the target temperature, it changes to a low-power operation mode to shorten the time for the room temperature to reach the target temperature and achieve energy saving of the central air conditioner. However, at the beginning of the startup of the central air conditioner, that is, when the central air conditioner operates in a high-power operation mode, since there are doors or windows, the indoor space is not airtight, and there may be heat dissipation equipment or refrigeration equipment and other cold / hot source points in the room. Both reasons may increase the time consumed for the room temperature to reach the target temperature, resulting in an extension of the time for the central air conditioner to operate in a high-power operation mode, reducing the cooling or heating efficiency of the central air conditioner and increasing resource waste.

[0081] Regarding the problem of resource waste caused by the time consumed to increase the room temperature to the target temperature, the inventor found that it can be achieved by: receiving a specific start instruction, and the position information of each temperature control point in the area where it is located and the energy generated per unit time; for each temperature control point, first obtain the effective air outlet corresponding to the temperature control point and the position information of the effective air outlet according to the area where the temperature control point is located and the corresponding relationship between the preset air outlet and the unit area; then obtain the working duration of the effective air outlet according to the energy generated per unit time corresponding to the temperature control point; then obtain the air outlet direction of the effective air outlet according to the position information of the temperature control point in the area where it is located and the position information of the effective air outlet corresponding to the temperature control point; finally, based on the specific start instruction, each effective air outlet, the working duration of each effective air outlet and the air outlet direction, operate the central air-conditioning system; so as to reduce the time for the central air-conditioning system to operate in a high-power operation mode and achieve energy-saving control of the central air-conditioning system.

[0082] The following further describes the embodiments of the present application in detail with reference to the accompanying drawings of the specification.

[0083] The embodiment of the present application provides a method for energy-saving control of a central air-conditioning system, which is executed by an energy-saving control device for a central air-conditioning system. The energy-saving control device for a central air-conditioning system can be a server or a terminal device. Among them, the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, and the embodiments of the present application do not limit this here. As Figure 1 shown, the method includes step S101, step S102, step S103, step S104, step S105 and step S106, where:

[0084] Step S101: Receive a specific start instruction, where the specific start instruction represents the preset operation mode of the central air-conditioning system.

[0085] Specifically, before the central air-conditioning system runs, the specific start instruction is sent to the central air-conditioning system through a mobile terminal. Among them, the specific start instruction can include the target temperature and target operation mode when the central air-conditioning system runs, and the target operation mode can at least include a cooling mode and a heating mode.

[0086] Step S102: Obtain the position information of each temperature control point in the area where it is located and the energy generated per unit time, where the temperature control point represents a point that affects the room temperature, and the area where the temperature control point is located is a preset unit area where the temperature control point is located.

[0087] Specifically, the method for obtaining the location information of each temperature control point area may include: obtaining through measurement or obtaining through imaging.

[0088] Preferably, the embodiment of the present application adopts the method of obtaining location information through imaging, which specifically includes: real-time monitoring through a surveillance video to determine whether a new temperature control point is added in each unit area, where the temperature control point is a device that may affect the indoor temperature, and the temperature control point may include cold / heat source points such as doors or windows, heat dissipation devices or refrigeration devices, and there is a unique corresponding air outlet in each unit area, and the air outlet is a structure for the central air-conditioning system to discharge air; if there is a new temperature control point, for each new temperature control point, it is determined whether there is any pre-stored device image that is the same as the image of the temperature control point in the surveillance video, where the pre-stored device image is the image pre-stored when each device is newly added in the public place where the central air-conditioning system is located. Determining whether the two images are the same can be determined by whether the Euclidean distance between the local feature vectors of each image is less than a set threshold. When it is less than or equal, it is determined to be the same, and when it is greater, it is determined to be different; if there is a pre-stored device image that is the same as the image of the new temperature control point, obtain the unit length set according to the actual situation, and based on the unit length and the device image of the new temperature control point, with the center point of the unit area as the coordinate origin, obtain the location information of the new temperature control point in the area where it is located, where the location information may be in the form of coordinates.

[0089] For the method of obtaining the energy generated by the temperature control point per unit time, it may specifically include: according to the pre-stored device image that is the same as the image of the new temperature control point, use the corresponding relationship between the pre-stored device image and the rated power of the device to obtain the rated power of the new temperature control point; obtain the unit time, and based on the unit time and the rated power of the new temperature control point, through the calculation formula for the energy generated per unit time, obtain the energy generated per unit time, where the unit time can set the dwelling value according to actual requirements, and the calculation formula for the energy generated per unit time may be: energy generated per unit time = unit time × rated power of the new temperature control point.

[0090] It can be understood that through the energy generated by each temperature control point per unit time, the degree of influence of each temperature control point on the room temperature per unit time can be obtained, which is no longer limited to the influence of temperature on temperature, but selects the more intuitive energy for the central air-conditioning system.

[0091] Step S103: For each temperature control point, according to the area where the temperature control point is located and the preset corresponding relationship between the air outlet and the unit area, obtain the effective air outlet corresponding to the temperature control point and the location information of the effective air outlet, where each effective air outlet represents the air outlet closest to the area where each temperature control point is located.

[0092] Specifically, for each temperature control point, according to the area where the temperature control point is located, by querying the preset correspondence between the air outlet and the unit area, the effective air outlet corresponding to the temperature control point is obtained. Among them, the correspondence preset during the installation of the central air-conditioning system can at least include the preset correspondence between the air outlet and the unit area, and the preset correspondence between the air outlet and the position information. For example, if the area where the M temperature control point is located is the No. 2 unit area, and in the preset correspondence between the air outlet and the unit area, the No. 2 unit area corresponds to the B air outlet, then the B air outlet is used as the effective air outlet of the M temperature control point; through the preset correspondence between the air outlet and the position information, the position information of the effective air outlet is obtained.

[0093] It can be understood that generally, the distance between the air outlet in the area where the temperature control point is located and the temperature control point is less than the distance between the air outlet corresponding to the unit area where the temperature control point is not located and the temperature control point; by using the preset air outlet in the unit area where the temperature control point is located as the effective air outlet and controlling the distance between the air outlet and the temperature control point to a smaller value, the energy consumption before the air outlet air reaches the temperature control point can be reduced.

[0094] Step S104: For each temperature control point, according to the energy generated per unit time corresponding to the temperature control point, obtain the working duration of the effective air outlet.

[0095] Specifically, the determination method of the working duration of the effective air outlet can include hierarchical determination or precise determination.

[0096] In one implementable manner, the hierarchical determination can specifically include: according to the energy generated per unit time corresponding to the temperature control point and the preset multiple energy ranges, determine the energy range in which the energy generated per unit time corresponding to the temperature control point is located. Among them, the preset multiple energy ranges can be obtained by evenly dividing the overall range of the energy generated per unit time composed of the maximum value and the minimum value of the energy generated per unit time; according to the energy range where it is located and the preset correspondence between the energy range and the working duration, obtain the working duration of the effective air outlet. Among them, the preset correspondence between the energy range and the working duration can be obtained through the median of each energy range and the rated power of the air outlet at the target temperature.

[0097] In another implementable manner, the precise determination can specifically include: according to the power of the central air-conditioning system operation and the energy generated per unit time of the temperature control point, through the energy calculation formula, calculate the working duration of the effective air outlet. Among them, the energy calculation formula can be: Energy = Power × Working Duration.

[0098] It can be understood that by calculating the working duration of each effective air outlet, the specific setting method of the central air-conditioning system to reach the target temperature in the area where the temperature control point is located can be determined. Among them, the specific setting method may include the target temperature of the central air-conditioning system, the target operation mode, and the working duration of each effective air outlet.

[0099] Step S105: For each temperature control point, based on the position information of the temperature control point in the area where it is located and the position information of the effective air outlet corresponding to the temperature control point, obtain the air outlet direction of the effective air outlet.

[0100] Specifically, for each temperature control point, based on the position information of the temperature control point in the area where it is located and the position information of the effective air outlet corresponding to the temperature control point, taking the effective air outlet as a fixed point, obtain the relative position between the temperature control point and the effective air outlet. Among them, the form of the relative position may include front, back, left, right, or a specific angle; based on the relative position between the temperature control point and the effective air outlet, determine the air outlet direction of the effective air outlet. Among them, the process of determining the air outlet direction based on the relative position may include taking the relative position between the temperature control point and the effective air outlet as the air outlet direction of the effective air outlet, or obtaining the air outlet direction corresponding to the relative position according to the relative position between the temperature control point and the effective air outlet and the preset corresponding relationship between the relative position and the air outlet direction.

[0101] It can be understood that the densities of cold air and hot air are different. When there is a certain air flow to promote the flow of cold and hot air, the fusion speed of cold and hot air can be increased. In the above embodiments, by controlling the air outlet direction of the effective air outlet, the exchange speed between cold and hot air in the area where the temperature control point is located is promoted, and the change speed of the room temperature in the area where the temperature control point is located is accelerated.

[0102] Step S106: Based on the specific start instruction, each effective air outlet, the working duration of each effective air outlet, and the air outlet direction, operate the central air-conditioning system.

[0103] Specifically, start and operate each effective air outlet of the central air-conditioning system at the target temperature and target operation mode of the specific start instruction. After successful startup, for each effective air outlet, adjust the air outlet direction of the effective air outlet, and make the effective air outlet work for the air outlet direction and the working duration; further, after the working time of the effective air outlet reaches the working duration, the air vanes of all air outlets can be made to operate in the swing mode, where the air vane is a structure for controlling the air outlet direction.

[0104] It can be understood that by promoting the exchange speed between hot and cold air in the area where the temperature control point is located, the room temperature in the area where the temperature control point is located is accurately controlled, and the time consumed for the overall room temperature to reach the target temperature is shortened.

[0105] In an embodiment of the present application, after receiving a specific start instruction, by obtaining the position information of each temperature control point in its area and the energy generated per unit time, the influence of each temperature control point on the room temperature can be determined; for each temperature control point, according to the area where the temperature control point is located and the preset corresponding relationship between the air outlet and the unit area, the effective air outlet corresponding to the temperature control point and the position information corresponding to the effective air outlet can be obtained. By using the preset air outlet in the unit area where the temperature control point is located as the effective air outlet, the energy consumption increased due to the long distance between the air outlet and the temperature control point can be reduced; for each temperature control point, according to the energy generated per unit time corresponding to the temperature control point, the working duration required for the effective air outlet to make the room temperature in the area where the temperature control point is located reach the target temperature can be determined; for each temperature control point, according to the position information of the temperature control point in its area and the position information of the effective air outlet corresponding to the temperature control point, the air outlet direction of the effective air outlet corresponding to the temperature control point can be obtained. By controlling the air outlet direction of the effective air outlet, the exchange between hot and cold air in the area where the temperature control point is located can be promoted, and the change speed of the room temperature in the area where the temperature control point is located can be accelerated; finally, based on the specific start instruction, each effective air outlet, the working duration of each effective air outlet, and the air outlet direction, the central air-conditioning system is operated. By promoting the exchange speed between hot and cold air in the area where the temperature control point is located, the room temperature in the area where the temperature control point is located is accurately controlled, the time consumed for the overall room temperature to reach the target temperature is shortened, the refrigeration or heating efficiency is improved, the operation time of the central air-conditioning system in the high-power operation mode is reduced, and the energy-saving control of the central air-conditioning system is realized.

[0106] A possible implementation manner of the embodiment of the present application, step S103 may specifically include steps S1031 to S1038 (not shown in the figure), where:

[0107] Step S1031: For each temperature control point, determine whether the area where the temperature control point is located is a target area with multiple temperature control points.

[0108] It can be understood that when there are multiple temperature control points in the same unit area, since there is only one air outlet for each unit area, there may be a situation where due to insufficient air outlet quantity, only one temperature control point can be covered by the air outlet direction of the air outlet, resulting in several temperature control points other than the temperature control point covered by the air outlet direction of the air outlet being ignored. Therefore, it is necessary to find the unit areas with multiple temperature control points to ensure that each temperature control point is covered by the air outlet direction of the air outlet, so as to efficiently make the room temperature reach the target temperature.

[0109] Specifically, if so, it indicates that there are multiple temperature control points in the area where the temperature control point is located, and it is necessary to match effective air outlets for all temperature control points except the current temperature control point; if not, it indicates that there is only the current temperature control point in the unit area where the temperature control point is located, and the unit area where the current temperature control point is located no longer participates in the process of determining the effective air outlet for the temperature control point.

[0110] Step S1032: If so, obtain the air outlet corresponding to the target area and the position information of the air outlet according to the preset corresponding relationship between the air outlet and the unit area.

[0111] Step S1033: Determine the effective temperature control points in the target area according to the position information of each temperature control point in the target area and the position information of the air outlet, where the effective temperature control point is the temperature control point closest to the air outlet.

[0112] Specifically, according to the position information of each temperature control point in the target area and the position information of the air outlet, the Euclidean distance formula can be used to calculate the distance between each temperature control point and the air outlet, and the temperature control point corresponding to the minimum Euclidean distance value is used as the effective temperature control point in the target area.

[0113] It can be understood that selecting the temperature control point closest to the air outlet in the target area as the effective temperature control point can reduce the energy consumption increased due to the long distance between the air outlet and the temperature control point.

[0114] Step S1034: Determine whether the effective temperature control point in the target area is the current temperature control point.

[0115] Specifically, it can be determined whether the effective temperature control point is the current temperature control point by judging whether the position information of the effective temperature control point in the target area and the position information of the current temperature control point in the target area are the same. When the position information is the same, it means that the effective temperature control point is the current temperature control point, and when the position information is different, it means that the effective temperature control point is different from the current temperature control point.

[0116] It can be understood that if so, it indicates that the current temperature control point has successfully obtained the effective air outlet, determine the effective air outlet for the current temperature control point, and start to judge whether there are multiple temperature control points in the area where the next temperature control point is located; if not, it indicates that the current temperature control point needs to continue to find the effective air outlet.

[0117] Step S1035: If so, use the air outlet corresponding to the target area and the position information of the air outlet as the effective air outlet corresponding to the temperature control point and the position information of the effective air outlet.

[0118] Step S1036: If not, determine whether there is any adjacent area of the target area that does not have a temperature control point.

[0119] Specifically, determine several adjacent areas of the target area, and judge whether there is any adjacent area of the target area that does not have a temperature control point according to the several adjacent areas and the areas where all the temperature control points are located respectively. Among them, the adjacent areas of the target area may be one or more. When the target area is surrounded by walls on three sides, the adjacent area is one, and when the target area is surrounded by walls on zero / one / two sides, the adjacent areas are multiple.

[0120] It can be understood that if it exists, it indicates that the air outlet of any adjacent area without a temperature control point can be used as the effective air outlet of the current temperature control point; if it does not exist, it indicates that the current temperature control point cannot match the corresponding effective air outlet.

[0121] Step S1037: If so, according to the preset correspondence between the air outlet and the unit area, obtain a number of alternative air outlets and the position information of a number of alternative air outlets, where each alternative air outlet represents the air outlet corresponding to each adjacent area without a temperature control point.

[0122] It can be understood that by using the air outlet of the adjacent area as the alternative air outlet of the current temperature control point, by selecting the adjacent area, the air outlets corresponding to multiple unit areas that are far away can be initially excluded.

[0123] Step S1038: Determine the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of a number of alternative air outlets.

[0124] Specifically, according to the position information of the current temperature control point and the position information of a number of alternative air outlets, obtain a number of adjacent boundaries, where the adjacent boundary represents the boundary line where the target area and the adjacent area meet; according to the position information of the current temperature control point and a number of adjacent boundary lines, obtain a number of first distances, where each first distance is the perpendicular distance from the current temperature control point to each adjacent boundary line; according to the position information of a number of alternative air outlets and the adjacent boundary corresponding to each alternative air outlet, obtain a number of second distances, where each second distance is the perpendicular distance between each alternative air outlet and the corresponding adjacent boundary; according to a number of first distances and a number of second distances, through a distance calculation formula, calculate the distance corresponding to each adjacent boundary, where the distance calculation formula can be distance = first distance + second distance; select the alternative air outlet corresponding to the smallest distance value as the effective air outlet of the current temperature control point.

[0125] It can be understood that by selecting the air outlet closest to the current temperature control point from a number of alternative temperature control points as the effective air outlet, the air outlets corresponding to a number of adjacent areas that are far away are excluded, and further, the energy consumption increased due to the long distance between the air outlet and the temperature control point is reduced.

[0126] In an embodiment of the present application, for each temperature control point, it is first determined whether the area where the temperature control point is located is a target area with multiple temperature control points, so as to ensure that the air outlet direction of the air outlet covers each temperature control point, and the room temperature can reach the target temperature efficiently; if so, according to the position information of the air outlet corresponding to the target area and the position information of each temperature control point in the target area within its area, the effective temperature control points are determined to reduce the energy consumption increased due to the long distance between the air outlet and the temperature control point; if the effective temperature control point in the target area is not the current temperature control point, it is judged whether there is any adjacent area in the target area without a temperature control point. If so, according to the position information of the current temperature control point and the position information of several alternative air outlets, the effective air outlet of the current temperature control point is determined, further reducing the energy consumption increased due to the long distance between the air outlet and the temperature control point.

[0127] A possible implementation manner of the embodiment of the present application may specifically further include before executing, for each temperature control point, determining whether the area where the temperature control point is located is a target area with multiple temperature control points:

[0128] Sort according to the energy generated by each temperature control point per unit time from large to small to obtain the sorting of all temperature control points.

[0129] It can be understood that the method for determining the effective air outlet for each temperature control point may include determining the effective air outlets of all temperature control points simultaneously, or determining the effective air outlet of each temperature control point in turn. Among them, the method of determining the effective air outlet of each temperature control point in turn may include determining the effective air outlet of each temperature control point in a random order or in a set order. Preferably, in the embodiment of the present application, it can be selected to sort based on the degree of influence of each temperature control point on the room temperature, and determine the effective air outlet of each temperature control point in turn according to the obtained sorting. Among them, the greater the energy generated by each temperature control point per unit time, the greater the degree of influence of each temperature control point on the room temperature.

[0130] Correspondingly, when step S1031 executes, for each temperature control point, determining whether the area where the temperature control point is located is a target area with multiple temperature control points, it may specifically include:

[0131] According to the sorting of all temperature control points, determine in turn whether the area where each temperature control point is located is a target area with multiple temperature control points.

[0132] In the embodiment of the present application, based on the principle that the greater the energy generated per unit time, the greater the influence of each temperature control point on the room temperature, the sorting of all temperature control points is obtained through the energy generated by each temperature control point per unit time. Then, based on the sorting of all temperature control points, the number of temperature control points in the area where each temperature control point is located is determined in turn. Since when the total number of temperature control points is greater than the total number of air outlets, there may be several temperature control points that cannot obtain effective air outlets. By first determining the effective air outlets for the temperature control points with a greater influence on the room temperature, the sum of the energy generated by several temperature control points that cannot obtain effective air outlets can be reduced, and the value of the work that the central air-conditioning system needs to do can be reduced, so as to increase the speed at which the room temperature reaches the target temperature.

[0133] A possible implementation manner of the embodiment of the present application may further specifically include steps SA1 (not shown in the figure) and SA2 (not shown in the figure) before determining the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of several alternative air outlets, where:

[0134] Step SA1: Obtain several filtered adjacent areas according to all adjacent areas of the target area and all preset key areas, where the filtered adjacent areas represent adjacent areas that are not key areas, and the key areas are preset areas with a large flow of people.

[0135] Specifically, obtain the daily average flow of people in each unit area, and according to the daily average flow of people in each unit area, determine the unit areas with a larger daily average flow of people as the preset key areas, where a larger daily average flow of people means a flow of people greater than the set threshold, and the set threshold can be set artificially according to the actual situation; according to all preset key areas, screen out the non-key areas in all adjacent areas of the target area to obtain several filtered adjacent areas, where the number of filtered adjacent areas may be 0 or one or more. When the number of non-key areas in all adjacent areas is equal to the number of adjacent areas, it is 0. When the number of non-key areas in all adjacent areas is greater than the number of adjacent areas, it is one or more. When the difference between the number of adjacent areas and the number of non-key areas in all adjacent areas is 1, it is one. When the difference between the number of adjacent areas and the number of non-key areas in all adjacent areas is greater than 1, it is multiple.

[0136] Step SA2: Obtain several filtered alternative air outlets according to the corresponding relationship between the preset air outlets and the unit areas and several filtered adjacent areas.

[0137] Correspondingly, when executing to determine the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of several alternative air outlets, it may specifically include:

[0138] Determine the effective air outlet of the current temperature control point according to the position information of the current temperature control point and the position information of several selected alternative air outlets.

[0139] In the embodiment of the present application, by screening out adjacent areas with low pedestrian flow in adjacent areas, several selected adjacent areas are obtained, which can reduce the probability that the air outlets in key areas are occupied by temperature control points in other unit areas, resulting in a slow rate of change of the room temperature in the key areas to the target temperature and a poor experience for the personnel in the key areas.

[0140] A possible implementation manner of the embodiment of the present application is that when step 1036 executes to obtain the working duration of the effective air outlet according to the energy generated per unit time corresponding to each temperature control point, it may specifically include step SB1 (not shown in the figure) and step SB2 (not shown in the figure), where:

[0141] Step SB1: Obtain the power corresponding to the target temperature according to the preset correspondence between the target temperature and the power and the target temperature.

[0142] Specifically, the preset correspondence between the target temperature and the power can be obtained according to the equipment parameters of the central air-conditioning system. Among them, the equipment parameters can be obtained through the instruction manual or relevant web pages of the central air-conditioning system, and at least include the rated power corresponding to each different target temperature. It should be noted that the rated power corresponding to each different target temperature is the rated power of each air outlet of the central air-conditioning system at different target temperatures.

[0143] Step SB2: Calculate the working duration of the effective air outlet according to the energy generated per unit time corresponding to each temperature control point and the power corresponding to the target temperature.

[0144] Specifically, according to the energy calculation formula, the calculation formula for the working duration is obtained. Among them, the calculation formula for the working duration is: working duration = energy generated per unit time ÷ power corresponding to the target temperature; according to the energy generated per unit time corresponding to each temperature control point and the power corresponding to the target temperature, the working duration of the effective air outlet is calculated through the calculation formula for the working duration.

[0145] It can be understood that in the embodiment of the present application, according to the determination method of the working duration of the effective air outlet in step S104, it may include hierarchical determination or precise determination. Preferably, the embodiment of the present application adopts the precise determination method, and the working duration of the effective air outlet is calculated according to the energy generated per unit time corresponding to each temperature control point and the power corresponding to the target temperature, so as to precisely control the working duration of the effective air outlet to operate at high power.

[0146] A possible implementation of the embodiment of the present application, step S105 may specifically include step SC1 (not shown in the figure) and step SC2 (not shown in the figure), where:

[0147] Step SC1: For each temperature control point, obtain the relative position between the temperature control point and the effective air outlet according to the position information of the temperature control point in the area where it is located and the position information of the effective air outlet corresponding to the temperature control point.

[0148] Specifically, the form of the relative position may include front, back, left, and right, or a specific angle. Preferably, the embodiment of the present application uses a specific angle to represent the relative position. Among them, the range of the specific angle may include [-180°, +180°] or [0°, 360°]. For example, when the range of the specific angle is selected as [0°, 360°], if the position information of temperature control point 1 is (10, 20) and the position information of effective air outlet 1 is (10, 10), then the relative position between temperature control point 1 and effective air outlet 1 is that temperature control point 1 is in the 0° direction of effective air outlet 1. If the position information of temperature control point 2 is (0, 20) and the position information of effective air outlet 2 is (10, 30), then the relative position between temperature control point 2 and effective air outlet 2 is that temperature control point 2 is in the 225° direction of effective air outlet 2.

[0149] Step SC2: For each effective air outlet, obtain the air outlet direction corresponding to the relative position according to the relative position between the temperature control point and the effective air outlet and the preset correspondence between the relative position and the air outlet direction.

[0150] Among them, in the preset correspondence between the relative position and the air outlet direction, the form of the relative position may be a specific angle, and the form of the air outlet direction may at least include four directions: front, back, left, and right. The number of forms of the air outlet direction can be artificially set according to the actual situation; specifically, when the relative position ∈ [-45°, 45°], the air outlet direction is forward, when the relative position ∈ [45°, 135°], the air outlet direction is right, when the relative position ∈ [135°, 225°], the air outlet direction is backward, and when the relative position ∈ [225°, 315°], the air outlet direction is left.

[0151] In the embodiment of the present application, after actually obtaining the relative position between the effective air outlet and the temperature control point, the air outlet direction is accurately determined according to the relative position, so that the exchange of hot and cold air in the area where the temperature control point is located can be accurately controlled, making the control of the room temperature in the area where the temperature control point is located more accurate.

[0152] A possible implementation of the embodiment of the present application, before step S101, may specifically further include step SD1 to step SD3 (not shown in the figure), where:

[0153] Step SD1: Obtain the initial specific start instruction and the previous specific start instruction, where the specific start instruction includes at least an operation mode.

[0154] The previous specific start instruction is the operation mode of the previous operation of the central air-conditioning system.

[0155] Step SD2: Determine whether the operation modes corresponding to the initial specific start instruction and the previous specific start instruction are the same.

[0156] Specifically, determine whether the operation mode in the initial specific start instruction is the same as the operation mode in the previous specific start instruction. If they are different, it indicates that there may be an error in the input of the initial specific start instruction, and it is necessary to confirm with the person who issued the initial specific start instruction whether the initial specific start instruction is correct. If they are the same, it indicates that there is no error in the operation mode input of the initial specific start instruction, and the central air-conditioning system can be operated based on the initial specific start instruction.

[0157] It can be understood that generally, the interval between the previous start of the central air-conditioning system and the current start of the central air-conditioning system is not too long, that is, the operation mode will not change. Therefore, when the operation mode of the previous start of the central air-conditioning system and the current start of the central air-conditioning system changes, it can be considered that there is an error in the specific start instruction.

[0158] Step SD3: If they are different, obtain a repeated confirmation instruction. After receiving the confirmation information corresponding to the repeated confirmation instruction, obtain the specific start instruction according to the confirmation information.

[0159] Specifically, if the operation modes are different, obtain a repeated confirmation instruction, and the central air-conditioning system pops up a repeated confirmation message on the mobile terminal, where the repeated confirmation message is used to ask the user whether the initial specific start instruction is correct; if the initial specific start instruction is correct, use the initial specific start instruction as the specific start instruction; if the initial specific start instruction is incorrect, re-obtain the initial specific start instruction and use the initial specific start instruction as the specific start instruction.

[0160] If the operation modes are the same, use the initial specific start instruction as the specific start instruction.

[0161] In the embodiment of the present application, by determining whether the operation modes corresponding to the initial specific start instruction and the previous specific start instruction are the same, to determine whether the initial specific start instruction is correct or incorrect, it is possible to prevent the central air-conditioning system from operating in an incorrect operation mode.

[0162] The above embodiments introduce an energy-saving control method for a central air-conditioning system from the perspective of the method flow. The following embodiments introduce an energy-saving control device for a central air-conditioning system from the perspective of virtual modules or virtual units. For details, see the following embodiments.

[0163] An embodiment of the present application provides an energy-saving control device for a central air-conditioning system, as Figure 2 shown. The energy-saving control device for the central air-conditioning system may specifically include:

[0164] A specific start instruction receiving module 201, configured to receive a specific start instruction, where the specific start instruction represents an operating mode of a preset central air-conditioning system;

[0165] A temperature control point data acquisition module 202, configured to acquire the position information of each temperature control point in the area where it is located and the energy generated per unit time, where the temperature control point represents a point that affects the room temperature, and the area where the temperature control point is located is a preset unit area where the temperature control point is located;

[0166] An effective air outlet determination module 203, configured to, for each temperature control point, obtain the effective air outlet corresponding to the temperature control point and the position information of the effective air outlet according to the area where the temperature control point is located and the corresponding relationship between the air outlet and the unit area preset, where each effective air outlet represents the air outlet closest to the area where each temperature control point is located;

[0167] A working duration determination module 204, configured to, for each temperature control point, obtain the working duration of the effective air outlet according to the energy generated per unit time corresponding to the temperature control point;

[0168] An air outlet direction determination module 205, configured to, for each temperature control point, obtain the air outlet direction of the effective air outlet according to the position information of the temperature control point in the area where it is located and the position information of the effective air outlet corresponding to the temperature control point;

[0169] An operation module 206, configured to operate the central air-conditioning system based on the specific start instruction, each effective air outlet, the working duration of each effective air outlet, and the air outlet direction.

[0170] For the embodiments of the present application, after receiving a specific start instruction, by obtaining the position information of each temperature control point in its area and the energy generated per unit time, the influence of each temperature control point on the room temperature can be determined; for each temperature control point, according to the area where the temperature control point is located and the preset corresponding relationship between the air outlet and the unit area, the effective air outlet corresponding to the temperature control point and the position information of the effective air outlet can be obtained. By using the preset air outlet in the unit area where the temperature control point is located as the effective air outlet, the energy consumption increased due to the long distance between the air outlet and the temperature control point can be reduced; for each temperature control point, according to the energy generated per unit time corresponding to the temperature control point, the working duration required for the effective air outlet to work can be determined so that the room temperature in the area where the temperature control point is located reaches the target temperature; for each temperature control point, according to the position information of the temperature control point in its area and the position information of the effective air outlet corresponding to the temperature control point, the air outlet direction of the effective air outlet corresponding to the temperature control point can be obtained. By controlling the air outlet direction of the effective air outlet, the exchange speed between hot and cold air in the area where the temperature control point is located can be promoted, and the change speed of the room temperature in the area where the temperature control point is located can be accelerated; finally, based on the specific start instruction, each effective air outlet, the working duration of each effective air outlet, and the air outlet direction, the central air-conditioning system is operated. By promoting the exchange speed between hot and cold air in the area where the temperature control point is located, the room temperature in the area where the temperature control point is located is accurately controlled, the time consumed for the overall room temperature to reach the target temperature is shortened, the refrigeration or heating efficiency is improved, the time for the central air-conditioning system to operate in a high-power operation mode is reduced, and the energy-saving control of the central air-conditioning system is realized.

[0171] In a possible implementation manner of the embodiments of the present application, when the effective air outlet determination module 203 executes to obtain the effective air outlet corresponding to the temperature control point and the position information of the effective air outlet according to the area where the temperature control point is located and the preset corresponding relationship between the air outlet and the unit area, it specifically is used for:
