[0002] In recent years, with the continuous development of China's economy, the national electricity demand has continued to rise, leading to a relatively tight power supply and demand relationship. Statistics show that in economically developed regions, air conditioners account for over 50% of electricity usage in summer, and this figure is showing a year-on-year upward trend. Adjusting air conditioners can participate in power balance control of the power supply and demand system, peak shaving and valley filling, and provide spinning reserve.

[0003] Current research on large-scale air conditioner clusters has found that while existing air conditioner controls prioritize user thermal comfort and can achieve good user satisfaction, their energy efficiency is not optimal in actual use, resulting in high energy consumption.

[0004] Therefore, existing technologies need further development. Summary of the Invention

[0007] Furthermore, the calculation method for the standard operating frequency is as follows: the standard operating power is the operating frequency corresponding to the indoor temperature at which the air conditioner maintains optimal thermal comfort under the current indoor environment.

[0008] Furthermore, the air conditioner cluster control method also includes: real-time detection and recording of outdoor temperature; if the change in outdoor temperature exceeds a preset threshold within a preset time, the standard operating frequency of the air conditioner is recalculated.

[0009] Furthermore, the single control mode specifically means: in cooling mode, controlling one air conditioner to operate at the minimum operating frequency; real-time monitoring of indoor temperature; if the indoor temperature exceeds the indoor temperature corresponding to the optimal thermal comfort, then controlling the air conditioner to adjust its operating frequency to the standard operating frequency.

[0010] Furthermore, the cluster control mode includes a first cluster control mode and a second cluster control mode. The first cluster control mode specifically involves: obtaining the turn-on sequence of air conditioners in different areas according to preset rules; controlling the air conditioners to operate at the optimal operating frequency in sequence according to the turn-on sequence; calculating the comprehensive operating frequency of the currently turned-on air conditioners; determining the relationship between the comprehensive operating frequency and the standard operating frequency; if the comprehensive operating frequency is greater than or equal to the standard operating frequency, then no more air conditioners will be turned on; if the comprehensive operating frequency is less than the standard operating frequency, then the air conditioners will continue to be turned on; when all air conditioners are turned on, determining the relationship between the comprehensive operating frequency and the standard operating frequency; if the comprehensive operating frequency is less than the standard operating frequency, then entering the second cluster control mode.

[0013] Furthermore, the method for dividing all air conditioners into n groups is as follows: the air conditioners are initially classified according to their engineering parameters, unit status parameters, and cumulative operating time; based on the classification results, each type of air conditioner is allocated to n groups in proportion to ensure that the operating frequency of each group of air conditioners is equal.

[0014] Furthermore, controlling each group of air conditioners to adjust its operating frequency according to a preset sequence specifically involves: numbering each group of air conditioners and sorting each group of air conditioners according to the number; turning off the air conditioner with the longest cumulative running time in each group according to the numbering order; and / or turning on the air conditioner with the shortest cumulative running time in each group according to the numbering order.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] Example 1:

[0026] According to an embodiment of the present invention, a method for cluster control of air conditioners is provided. Please refer to [link to relevant documentation]. Figures 1 to 5 ,include:

[0027] S100 obtains the optimal thermal comfort level corresponding to the current environment, and the indoor temperature corresponding to the optimal thermal comfort level;

[0028] The S200 obtains the standard operating frequency of the air conditioner based on the indoor temperature corresponding to the optimal thermal comfort.

[0029] S300 compares the air conditioner's standard operating frequency with its optimal operating frequency.

[0030] If the standard operating frequency of the air conditioner is less than or equal to the optimal operating frequency of the air conditioner, then the S400 will control one air conditioner and enter a single control mode.

[0031] If the standard operating frequency of the S500 air conditioner is greater than its optimal operating frequency, the S500 will turn on the air conditioners in different areas sequentially according to preset rules, entering the cluster control mode.

[0032] By adopting the above settings, the indoor temperature that is comfortable for the human body under the current environment is obtained based on outdoor environmental factors, and the indoor temperature is adjusted accordingly. By combining single-unit control and cluster control, the indoor environment is maintained at a comfortable temperature. While improving user satisfaction, cluster control can more fully tap the demand response potential of cluster air conditioning load while maintaining a comfortable indoor temperature, improve cluster capacity and energy efficiency, and balance user thermal comfort with maximum reduction of air conditioning load, thereby reducing energy consumption while improving user thermal comfort.

[0033] In the air conditioner cluster control method of this embodiment, the calculation method of the standard operating frequency is as follows: the standard operating power is the operating frequency corresponding to the indoor temperature at which the air conditioner maintains the optimal thermal comfort level under the current indoor environment. Thus, with the goal of maximizing user thermal comfort and reducing air conditioning load, the indoor temperature corresponding to the optimal thermal comfort level of the inverter air conditioner's single-unit constant temperature control is determined. Then, based on the indoor temperature corresponding to the optimal thermal comfort level of the inverter air conditioner's single-unit constant temperature control, the operating frequency of the air conditioner required to maintain this temperature is obtained, i.e., the standard operating frequency. At the standard operating frequency, the air conditioner can achieve operation with minimal energy consumption while meeting customer comfort requirements.

[0034] In the air conditioner cluster control method of this embodiment, the method further includes: real-time detection and recording of outdoor temperature; if the change in outdoor temperature exceeds a preset threshold within a preset time, the standard operating frequency of the air conditioner is recalculated. Thus, when the outdoor temperature changes significantly, the optimal thermal comfort level is recalculated based on the rate of change, and the corresponding indoor temperature is calculated based on the new optimal thermal comfort level. The standard operating frequency of the air conditioner is then set, allowing the standard operating frequency to more flexibly adapt to user comfort.

[0035] In the air conditioner cluster control method of this embodiment, the single control mode is specifically as follows: in the cooling state, control one air conditioner to operate at the minimum operating frequency; monitor the indoor temperature in real time; if the indoor temperature exceeds the indoor temperature corresponding to the optimal thermal comfort, control the air conditioner to adjust its operating frequency to the standard operating frequency.

[0036] In practice, common air conditioning units for users include fixed-frequency air conditioners and variable-frequency air conditioners. Fixed-frequency air conditioners operate with a constant compressor power and only have two working states: stopped and rated frequency. The indoor temperature is controlled within a certain range by intermittently starting and stopping the compressor. Variable-frequency air conditioners use variable-frequency compressors, and the compressor frequency changes with the indoor temperature, thereby maintaining the temperature at a constant value.

[0037] Specifically, inverter air conditioners can control room temperature and power consumption by adjusting the operating frequency of the air conditioner. Let the indoor temperature corresponding to the optimal thermal comfort level be T (hereinafter referred to as the air conditioner's "optimal temperature"). When the inverter air conditioner is running automatically, the characteristic of its operating frequency change can be expressed as the air conditioner frequency f at the next moment. t+1 , specifically,

[0038]

[0039] In practice, in the initial stage of the single control mode, the air conditioner compressor operates at the power corresponding to the minimum frequency. When the room temperature Ts reaches the set optimal temperature T, the air conditioner power jumps to the standard operating frequency and remains constant. The control objective of a single air conditioner is to achieve the optimal combination of user air conditioning load reduction and comfort.

[0040] Preferably, the control of a single air conditioner follows the following principle: when the recalculated and set standard operating frequency is higher than the optimal operating frequency of the single air conditioner, or when the operating frequency is not met and needs to be increased, the air conditioner's control mode enters the cluster control mode to ensure that each air conditioner in the air conditioner group can operate at the optimal operating frequency for high efficiency and energy saving.

[0041] Preferably, the control of a single air conditioner follows a user thermal comfort control strategy. The user's thermal sensation is divided into seven scales: cold, cool, slightly cool, moderate, slightly warm, warm, and hot. The user's thermal comfort is fed back to these seven scales through thermal balance. Thermal balance is an equation formed by the human body's heat output and the reference heat, which is quantified and fed back to the seven scales. Moderate means no adjustment is needed. Cold, hot, cool, warm, slightly warm, and slightly cool represent different adjustment rates k values ​​in opposite directions for the current state. Cold and hot mean that rapid adjustment is needed, which is fed back to the air conditioner and is also a rapid adjustment of the compressor frequency. Slightly warm and slightly cool mean that the air conditioner is fine-tuned to make the room temperature serve the user's thermal sensation.

[0042] Specifically, the assessment of the human body's thermal balance, which is the difference between the amount of heat generated and the amount of heat dissipated, is used to input the difference into a regression curve, which can reflect seven scales of the user's thermal sensation. Among them, the amount of heat generated is the difference between the amount of metabolism and the amount of work done; the amount of heat dissipated includes four parts: heat dissipation through the skin, heat dissipation through perspiration, heat dissipation through respiration, and heat loss through clothing.

[0043] In the air conditioner cluster control method of this embodiment, the cluster control mode includes a first cluster control mode and a second cluster control mode. The first cluster control mode specifically involves: obtaining the turn-on sequence of air conditioners in different areas according to preset rules; controlling the air conditioners to operate at the optimal operating frequency in sequence according to the turn-on sequence; calculating the comprehensive operating frequency of the currently turned-on air conditioners; determining the relationship between the comprehensive operating frequency and the standard operating frequency; if the comprehensive operating frequency is greater than or equal to the standard operating frequency, then no more air conditioners are turned on; if the comprehensive operating frequency is less than the standard operating frequency, then the air conditioners continue to be turned on; when all air conditioners are turned on, determining the relationship between the comprehensive operating frequency and the standard operating frequency; if the comprehensive operating frequency is less than the standard operating frequency, then entering the second cluster control mode.

[0044] Specifically, based on the collected information, with the goal of achieving the optimal combination of user thermal comfort and air conditioner operating frequency, the optimal temperature and related setting parameters for the constant temperature control of a single variable frequency air conditioner are calculated, a non-group control strategy for the air conditioning group (i.e., the first cluster control mode) is established, and the number of air conditioners in each group and the start time of rotation control are determined.

[0045] The first cluster control mode uses a single-unit control method for all air conditioners. Therefore, in the non-group control mode, the load reduction of the air conditioner group at each sampling time is the sum of the single-unit power reduction of all air conditioners at that time.

[0046] In the air conditioner cluster control method of this embodiment, the preset rules include: sorting the air conditioner turn-on order according to environmental parameters; and / or, sorting the air conditioner turn-on order according to installation location.

[0047] In practice, once the first cluster control mode is entered, the start and stop of the air conditioner will be affected by engineering parameters. At this time, parameters such as the installation location of the air conditioner, installation distance, wind direction, and weather will all affect the start sequence of the air conditioner in the first cluster control mode.

[0048] Specifically, the method for sorting the turn-on sequence of the air conditioners based on environmental parameters such as wind direction and weather includes:

[0049] The air conditioners are turned on in sequence according to the wind direction. Specifically, since the air source heat pump uses a high-efficiency finned coil heat exchanger, the excellent outdoor wind direction and weather conditions help the air conditioner finned heat exchanger to exchange heat efficiently. The ambient wind direction at time t is collected to determine the best wind direction for the relative position of a single air conditioner in the cluster (i.e., the single air conditioner with the largest fin windward surface area) and it is turned on first.

[0050] The order in which the air conditioners are turned on is determined based on weather conditions. Specifically, different weather conditions have different impacts on the cluster, with particularly severe weather such as snow and ice having a greater impact on the air conditioners. All air conditioners are equipped with phone cards for internet access, allowing them to view and check weather forecasts. Different control methods are used for different weather conditions. For example, in rainy weather, conditions favorable for cooling are achieved. In this case, the compressor frequency is appropriately reduced to save energy, maximizing user thermal comfort and minimizing the air conditioning load. In snowy weather, snow accumulation on the air conditioners poses a significant hazard, ranging from causing the fan blades to become unbalanced to, in severe cases, causing irreversible damage due to fan reversal. In such cases, when snow accumulation is detected, snow removal measures are implemented before starting the air conditioners. During initial startup, the fan starts at a low frequency, drawing the snow into the drip tray in reverse. Subsequently, as the air conditioner defrosts, the heat generated melts the snow into water, which is then drained through the drain pipe.

[0051] Specifically, the method for sequencing the start-up order of the air conditioners according to the engineering installation includes: First, when the operating frequency requirement is met, a single air conditioner is not allowed to operate at a higher operating frequency to meet the requirement. Instead, multiple air conditioners operate in their high-efficiency zones to ensure that their combined operating frequency meets the requirement. When the combined operating frequency is not met, the next air conditioner is turned on sequentially. At this point, the air conditioner in the cluster that is turned on follows the principle of furthest distance. Assuming the first air conditioner turned on is the master unit, when the combined operating frequency is not met, the next slave unit to be turned on must be the air conditioner furthest from the master unit, avoiding the heat island effect and preventing adjacent air conditioners from "competing" for airflow.

[0052] Specifically, each air conditioner is equipped with a telephone card for positioning. This allows the system to determine the location of each module in the positioning cluster. Once the host is turned on, the system radiates outwards from the host, and the location parameters can be used to guide the air conditioner's start and stop when the load is increased or decreased.

[0053] See Figure 4 When air conditioners are installed in a row, they can be turned on sequentially, such as units 1, 3, 5, 7, etc., instead of sequentially turning on units 1, 2, 3, 4, etc. For irregularly installed air conditioners, please refer to [reference needed]. Figure 5 When machine number 1 is turned on, it becomes the primary source for radiation. The second machine is turned on following the principle of maximizing distance, starting with machine number 7. This process continues until machines number 6, 3, 5, 4, and 2 are turned on in that order.

[0054] In the air conditioner cluster control method of this embodiment, the second cluster control mode specifically involves: calculating the frequency difference between the current air conditioner's comprehensive operating frequency and the standard operating frequency; dividing the currently active air conditioners into n groups; dividing the frequency difference n equally to obtain the operating frequency that each group of air conditioners needs to adjust; and controlling each group of air conditioners to adjust its operating frequency according to a preset sequence until the comprehensive operating frequency equals the standard operating frequency. Thus, the second cluster control mode further employs a grouping control strategy for the air conditioner cluster based on the control results of the first cluster control mode. Assuming there are N controllable air conditioners in the cluster, the cluster is first initially classified based on the air conditioner's characteristic attributes. After obtaining the air conditioner classification results, each type of air conditioner is proportionally allocated to n air conditioner groups, where each group has n1, n2, ... n... i Since each group of air conditioners includes the same type of air conditioner, the operating power and average operating frequency of each group of air conditioners before control are also the same. Based on this, the frequency difference between the current comprehensive operating frequency of the air conditioner and the standard operating frequency is calculated, and the difference is divided into n equal parts. The difference after equal division is the frequency that each group of air conditioners needs to adjust.

[0055] In the air conditioner cluster control method of this embodiment, the method of dividing all air conditioners into n groups is as follows: Air conditioners are initially classified according to their engineering parameters, unit status parameters, and cumulative operating time; based on the classification results, each type of air conditioner is proportionally allocated to n groups so that the operating frequency of each group of air conditioners is equal. Specifically, the air conditioner characteristic attributes include: engineering parameters, unit status parameters, and cumulative operating time. Air conditioners with common characteristics are grouped together; for example, when classifying by installation location, a row of air conditioners is grouped together; or when classifying by cumulative operating time, air conditioners with the same cumulative operating time range are grouped together.

[0056] In the air conditioner cluster control method of this embodiment, controlling each group of air conditioners to adjust its operating frequency according to a preset order specifically involves: numbering each group of air conditioners, and sorting each group of air conditioners according to the number; turning off the air conditioner with the longest cumulative running time in each group according to the number sorting; and / or turning on the air conditioner with the shortest cumulative running time in each group according to the number sorting.

[0057] Specifically, the second cluster control mode adopts a single control method within the group. The control follows the following principles: taking the classification by the cumulative running time of the compressor as an example, the compressor with the shorter cumulative running time is shut down last. If the running time is the same, the compressor is sorted according to the pre-set unit number, and the compressor with the lower number is turned on first.

[0058] See Figure 5 When increasing or decreasing the operating frequency, in the second cluster control mode, one air conditioner is started or turned off in each group, rather than being turned on or off one by one in a single group.

[0059] Specifically, if the operating frequency of one unit in the first group is insufficient, then one unit in the second group is activated instead of two units in the first group, and so on.

[0060] In practice, the second cluster control mode adopts a group start-stop control method. To avoid excessively long cumulative operation of a single unit, a round-robin control method is used, with the start time of each group's round-robin control recorded as t1, t2, ..., t n After grouping is completed, the rotation control starts at time t. j At that time, the air conditioners in group j start simultaneously, and the air conditioners in the group are still controlled according to a single control mode.

[0061] This embodiment provides an air conditioner, see [link / reference] Figure 3The air conditioner includes: a data acquisition unit, which acquires the optimal thermal comfort level for the current environment and the indoor temperature corresponding to the optimal thermal comfort level; a calculation unit, which calculates the standard operating frequency of the air conditioner based on the indoor temperature corresponding to the optimal thermal comfort level; and a control unit, which compares the standard operating frequency of the air conditioner with its optimal operating frequency. If the standard operating frequency of the air conditioner is less than or equal to its optimal operating frequency, then one air conditioner is controlled, entering a single control mode; if the standard operating frequency of the air conditioner is greater than its optimal operating frequency, then the air conditioners in different areas are turned on sequentially according to preset rules, entering a cluster control mode.

[0062] By adopting the above settings, the indoor temperature that is comfortable for the human body under the current environment is obtained based on outdoor environmental factors, and the indoor temperature is adjusted accordingly. By combining single-unit control and cluster control, the indoor environment is maintained at a comfortable temperature. While improving user satisfaction, cluster control can more fully tap the demand response potential of cluster air conditioning load while maintaining a comfortable indoor temperature, improve cluster capacity and energy efficiency, and balance user thermal comfort with maximum reduction of air conditioning load, thereby reducing energy consumption while improving user thermal comfort.

When the air conditioning unit starts to run, it determines whether the air conditioning load (i.e. the air conditioning operating frequency) meets the optimal operating frequency corresponding to the air conditioner.

[0066] If the requirements are not met, adjust the air conditioner's operating frequency to the optimal operating frequency;

[0067] If satisfied, determine whether the air conditioner's operating frequency meets the standard operating frequency that satisfies the optimal thermal comfort under the current environment.

[0068] If not, adjust the air conditioner's operating frequency to the standard operating frequency;

[0069] If the conditions are met, then the first cluster control mode is activated;

[0070] Determine whether the overall operating frequency of the air conditioning cluster under the first cluster control mode meets the standard operating frequency;

[0071] If the conditions are met, the current operating state will be maintained;
