[0002] Multi-unit air conditioning systems are coupled and complex systems containing multiple units. In practical applications, different combinations of these units can produce varying operating effects, resulting in significant differences in system energy efficiency. Currently, the configuration of combinations within multi-unit air conditioning systems is primarily based on the experience of the operators.

[0003] However, this method of combining multiple units based on the staff's own experience is prone to problems due to differences in the staff's experience, such as unreasonable settings leading to abnormal system operation and failure to meet cooling / heating requirements.

No specific limitations are imposed here.

[0067] like Figure 1 As shown, the method specifically includes:

[0068] S101, Obtain the operation strategy table corresponding to the multi-unit air conditioning system, wherein the operation strategy table contains multiple unit combinations and the combination parameters corresponding to each unit combination.

[0069] The operation strategy table is used to assist operators in controlling the operation of multi-unit air conditioning systems. This table contains various unit combinations and corresponding combination parameters for each combination. In application, the combination parameters generally include load rate range and workload range. The load rate range is used to limit the rate of reduction in unit capacity and the magnitude of the load rate increase. The workload range includes the cooling capacity range (i.e., the cooling capacity range of the unit combination) and the heating capacity range (i.e., the heating capacity range of the unit combination).

[0070] Figure 2 The table shown is an example of an operation strategy table, such as... Figure 2 As shown, the operation strategy table includes 8 unit combinations, numbered 1-8. That is, each row in the operation strategy table represents a unit combination. When the user selects unit combination 1, the LVE730EF unit in the multi-unit air conditioning system will start operating. When the user selects unit combination 6, the 750HGTY unit, LVE730EF unit, QW560EF unit, and CVE830HG unit in the multi-unit air conditioning system will start operating.

[0071] S102, the operation strategy table is displayed through a visualization component, and strategy modification information based on the operation strategy table is received through the visualization component.

[0072] Strategy modification information refers to information input by the user to modify the operating strategy table. For example, information to modify the units included in each unit combination, and information to modify the operating parameters of the unit combination (such as the load factor for adding units and the compliance rate for reducing units).

[0073] In applications, when staff perform actual control of multi-unit air conditioning systems, there are situations where they need to modify the operation strategy table. To facilitate user modifications to the operation strategy table, this embodiment of the application can display the operation strategy table through a visualization component, such as... Figure 3 and Figure 4 The image shown is a schematic diagram of the interface display of the visualization component. In this way, users can input corresponding strategies and modify information through the visualization component.

[0074] S103, the rationality of the policy modification information is determined based on the preset policy restriction rules and the combined parameters, and the corresponding determination result is obtained.

[0075] S104, Based on the determination result, generate corresponding modification guidance information to instruct the user to modify the operation strategy table based on the modification guidance information to obtain the target operation strategy table.

[0076] The following provides a unified explanation of S103 and S104:

[0077] Policy restriction rules are used to limit the policy modification information entered by users, so as to avoid the policy modification information entered by users being unreasonable.

[0078] Strategy guidance information is used to point out the unreasonable aspects of the strategy modification information entered by the user, and to assist the user in entering reasonable strategy modification information.

[0079] In applications, due to differences in staff experience, improper settings during modifications to the operational strategy table can easily lead to system malfunctions and failure to meet cooling / heating demands. Therefore, in this embodiment, the reasonableness of user-inputted strategy modification information can be determined based on preset strategy restriction rules, yielding a judgment result that includes both reasonable and unreasonable outcomes.

[0080] If the policy modification information entered by the user is reasonable, the running policy table can be directly modified according to the policy modification information to obtain the target running policy table. However, if the policy modification information entered by the user is unreasonable, corresponding modification guidance information can be generated to instruct the user to enter reasonable policy modification information based on the modification guidance information to modify the running policy table to obtain the target running policy table.

[0081] In one embodiment, the strategy modification information includes: reduced load rate and increased load rate, and the combined parameters include: a reference load rate range. The specific implementation of determining the reasonableness of the strategy modification information based on preset strategy restriction rules and the combined parameters to obtain the corresponding determination result may include the following steps:

[0082] Determine whether the reduced load rate and the added load rate are within the range of the reference load rate. If both the reduced load rate and the added load rate are within the range of the reference load rate, determine whether the reduced load rate is less than or equal to the added load rate. If the reduced load rate is less than or equal to the added load rate, determine that the judgment result corresponding to the strategy modification information is reasonable.

[0083] For example, the load rate range is: 30% ≤ Reduced load rate ≤ Added load rate ≤ 100%. When a user modifies the added or reduced load rate in any row, if it falls within this range, the corresponding judgment result is considered reasonable. If it falls outside this range, the corresponding modification guidance information will be displayed, prompting "Load rate must meet 30% ≤ Reduced load rate ≤ Added load rate ≤ 100%", and the modification will be prevented. This avoids system malfunctions caused by unreasonable parameter settings.

[0084] In another embodiment, the policy modification information includes: first combined modification information. The specific implementation of determining the reasonableness of the policy modification information based on preset policy restriction rules and the combined parameters to obtain the corresponding determination result may include the following steps:

[0085] Step A1: Modify the unit combination in the operation strategy table based on the first combination modification information to obtain a first reference strategy table, wherein the first reference strategy table contains multiple first reference unit combinations;

[0086] Step A2: Determine the third rated workload corresponding to each first reference unit combination, and sort all the first reference unit combinations in ascending order of the corresponding third rated workload;

[0087] Step A3: Determine the workload range corresponding to each of the first reference unit combinations;

[0088] Step A4: For each first reference unit combination, determine whether the upper limit of the workload range corresponding to the first reference unit combination is within the workload range corresponding to the next first reference unit combination.

[0089] Step A5: If the upper limit of the workload range corresponding to each first reference unit combination is within the workload range corresponding to the next first reference unit combination, then the determination result corresponding to the strategy modification information is deemed reasonable.

[0090] The first set of modification information refers to the user's modifications to the units included in any one or more unit combinations. For example, the user's modifications to... Figure 2If the first row of the operation strategy table is modified and the QW560EF unit is selected, then for the modified first reference strategy table, the first row of the table corresponds to the first unit combination containing the LVE730EF unit and the QW560EF unit.

[0091] The third rated workload refers to the rated cooling or heating capacity of the corresponding unit combination.

[0092] In applications, the workload range can be calculated using the following formula:

[0093] Cooling capacity range = sum of the design cooling capacity of the internal chillers in the unit combination * (reduced load rate 30%, increased load rate 100%); Heating capacity range = sum of the design heating and cooling capacity of the internal chillers in the unit combination * (reduced load rate 30%, increased load rate 100%).

[0094] by Figure 2 Taking the second row of the operation strategy table as an example, when a user modifies the selection of units included in the second row, according to this scheme, it can be determined that: the sum of the total cooling capacity of the chillers in the previous row (i.e., the first row) ≤ the sum of the total cooling capacity of the chillers selected in the second row ≤ the sum of the total cooling capacity of the chillers in the previous row / (default parameter (30%)). If this condition is not met, the modified "√" will remain red, prompting the user that "there is a problem with the unit combination in this row, and the cooling capacity range should be between (the sum of the total cooling capacity of the chillers in the previous row ~ the sum of the total cooling capacity of the chillers in the previous row / (default parameter (30%)))). If this condition is met, the judgment result corresponding to the strategy modification information is reasonable, the user's modification turns into a blue "√", and the operation strategy table is modified according to the strategy modification information.

[0095] In application, when the judgment result corresponding to the modified information according to the above scheme and judgment strategy is reasonable, the reference load rate range for reducing chillers can also be judged: Whether 30% (default lower limit of the reduction compliance rate) ≤ the maximum value of the cooling capacity segment in the previous row / the total cooling capacity of the chillers already selected in this row, and simultaneously, whether 30% ≤ the reduction load rate ≤ (the maximum value of the cooling capacity segment in the previous row / the total cooling capacity of the chillers already selected in this row), and whether 30% ≤ the reduction load rate ≤ the addition load rate ≤ 100%. If these conditions are not met, the load rate in this row will turn red, and the message "The addition load rate setting in the previous row is too low, please adjust" will be displayed. This avoids situations where unreasonable parameter settings lead to abnormal system operation.

[0096] This embodiment ensures that the workload range of each row of units is continuous, that is, the upper limit of the previous workload can process the range of the next workload.

[0097] In the application, a "full start judgment" can also be performed on multiple first reference unit combinations contained in the first reference strategy table. That is, it can be judged whether there is a unit combination in the first reference strategy table that contains all the units in the multi-unit air conditioning system. If not, the user will be prompted "Some units have not been fully applied. Please continue to add strategies".

[0098] by Figure 2 Taking the operating strategy table shown as an example, the unit combination in row 8 includes all units in a multi-unit air conditioning system. Therefore... Figure 2 The running strategy table shown conforms to the principle of "full startup judgment". If, Figure 2 The operating strategy table shown only contains unit combinations from rows 1 to 7, which does not meet the principle of "full start-up judgment". This scheme can avoid the situation where units are not fully utilized.

[0099] In another embodiment, the policy modification information includes: second combined modification information. The specific implementation of determining the reasonableness of the policy modification information based on preset policy restriction rules and the combined parameters to obtain the corresponding determination result may include the following steps:

[0100] Step B1: Modify the unit combination in the operation strategy table based on the second combination modification information to obtain a second reference strategy table, wherein the second reference strategy table contains multiple second reference unit combinations;

[0101] Step B2: Determine the fourth rated workload corresponding to each second reference unit combination, and sort all the second reference unit combinations in the second reference strategy table in ascending order of the corresponding fourth rated workload to obtain the third reference strategy table.

[0102] Step B3: For each second reference unit combination in the third reference strategy table, determine the two second reference unit combinations that are ranked before the second reference unit combination and adjacent to the second reference unit combination as the third reference unit combination;

[0103] Step B4: Determine the upper limit of the workload range corresponding to the third reference unit combination, and determine the ratio of the upper limit of the workload range to the total workload corresponding to the second reference unit combination;

[0104] Step B5: If the ratio corresponding to each of the second reference unit combinations is less than or equal to the load reduction rate corresponding to the second reference unit combination, the determination result corresponding to the strategy modification information is deemed reasonable.

[0105] The second set of modification information refers to the modification information made by the user to the units included in any one or more unit combinations.

[0106] The fourth rated workload refers to the rated cooling or heating capacity of the corresponding unit combination.

[0107] In this embodiment, the system determines whether there is an overlap in workload between two unit combinations by judging whether the ratio corresponding to each second reference unit combination is less than or equal to the load reduction rate corresponding to the second reference unit combination. That is, if the maximum workload of the third reference unit combination (e.g., the maximum cooling capacity) / the total workload of the second reference unit combination (e.g., the total cooling capacity) ≤ the load reduction rate of this row, then there is no overlap in workload between two unit combinations in the current third reference strategy table. Otherwise, if there is an overlap in workload between two unit combinations in the current third reference strategy table, it may cause the system to be unable to determine which combination to switch to when switching unit combinations.

[0108] This embodiment can prevent more than two unit combinations from simultaneously meeting the operating point during the switching of unit combinations, thereby avoiding abnormal system operation, such as frequent start-stop of units in the system.

[0109] In this embodiment, firstly, an operation strategy table corresponding to a multi-unit air conditioning system is obtained. This table includes various unit combinations and corresponding combination parameters for each combination. Then, the operation strategy table is displayed through a visualization component, and strategy modification information based on the table is received via this component. Next, the rationality of the modification information is determined based on preset strategy restriction rules and the combination parameters, resulting in a corresponding determination result. Finally, modification guidance information is generated based on the determination result to instruct the user to modify the operation strategy table to obtain the target operation strategy table. This application guides staff to rationally combine multiple units in a multi-unit air conditioning system, thereby avoiding system malfunctions due to improper settings.

[0110] See Figure 5 This is a flowchart illustrating another embodiment of the guidance information generation method provided in this application. Figure 5 The process shown above Figure 1 Based on the illustrated process, describe how to obtain the operating strategy table corresponding to a multi-unit air conditioning system. For example... Figure 5 As shown, the process may include the following steps:

[0111] S501, Obtain at least two units included in the multi-unit air conditioning system;

[0112] S502, determine the first rated operating load and reference load corresponding to at least two of the said units;

[0113] S503, the ratio of the reference load to the first rated workload is determined as the workload percentage;

[0114] S504, based on the workload ratio and the preset multiple ratio ranges, determine the first reasonable selection result of the multi-unit air conditioning system.

[0115] S505, if the first selection result is reasonable, generate the operation strategy table based on at least two of the units.

[0116] The following provides a unified explanation of S501-S505:

[0117] In this embodiment, for all units in a multi-unit air conditioning system, the rationality of the unit selection in the multi-unit air conditioning system is determined by whether the first rated workload (i.e., rated cooling / heating capacity) of all units meets the reference load (i.e., design cooling / heating load).

[0118] Specifically, the workload percentage is calculated using the following formula:

[0119] Cooling ratio = Design cooling load / Sum of rated cooling capacity of unit;

[0120] Heating ratio = Design heat load / Unit rated heat capacity;

[0121] Then, the rationality of the selection is diagnosed by combining the proportion of cooling and heating.

[0122] In another embodiment, the method may further include the following steps: if the first reasonable selection result is unreasonable, based on the proportion range of the workload proportion, determine the corresponding selection prompt information, and display the selection prompt information to instruct the user to reselect the multi-unit air conditioning system. This provides the user with corresponding analytical opinions to assist in making a reasonable selection.

[0123] As an example, the rationality of selecting a multi-unit air conditioning system can be judged based on the various situations shown in Tables 1 and 2, and analytical opinions can be provided.

[0124] Table 1:

[0125]

[0126] Table 2

[0127]

[0128]

[0129] This embodiment can assist users in making reasonable selections of units in a multi-unit air conditioning system. When the selection is reasonable, an operation strategy table can be generated based on multiple units in the multi-unit air conditioning system, thereby avoiding abnormal system operation due to unreasonable selection.

[0130] Specifically, the operation strategy table can be generated through the following steps: Arbitrarily combine at least two of the units to obtain multiple unit combinations; determine the second rated workload corresponding to each unit combination; sort all the unit combinations in ascending order of the corresponding second rated workload to obtain a strategy table to be confirmed; determine the workload range corresponding to each unit combination in the strategy table to be confirmed; for each unit combination, determine whether the upper limit of the workload range corresponding to the unit combination is within the workload range corresponding to the next unit combination; if the upper limit of the workload range corresponding to each unit combination is within the workload range corresponding to the next unit combination, the multi-unit air conditioning system selection is deemed reasonable, and the strategy table to be confirmed is determined as the operation strategy table.

[0131] In this embodiment, firstly, all units are combined. For example, in a multi-unit air conditioning system with four units (a, b, c, and d), the following combinations are possible: one unit combination (a, b, c, d); two units combination (ab, ac, ad, bc, bd, cd); three units combination (abc, abd, bcd); and four units combination (abcd). Then, the units are sorted from smallest to largest according to their rated cooling / heating capacity. Using the cooling / heating capacity calculation formula, the cooling / heating capacity range for each combination is calculated. Finally, it is determined whether the upper limit of each cooling / heating capacity range falls within the range of the next cooling / heating capacity range. If so, the selection is correct, and an operating strategy table is obtained; otherwise, the user is prompted that "the unit selection capacity ratio is unreasonable; please adjust."

[0132] The calculation formulas for the cold / heat segment are as follows:

[0133] Cooling capacity range = sum of the design cooling capacity of the internal chillers in the unit combination * (reduced load rate 30%, increased load rate 100%); Heating capacity range = sum of the design heating and cooling capacity of the internal chillers in the unit combination * (reduced load rate 30%, increased load rate 100%).

[0134] by Figure 2 Taking the first and second rows of the operation strategy table as an example, the upper limit of the cooling capacity segment corresponding to the first row is 180, and the cooling capacity segment corresponding to the second row is 170-270. Since 180 is within the range of 170-270, the settings of the first and second rows are reasonable. By analogy, each row is judged. If all the settings are reasonable, then the unit selection is determined to be reasonable.

[0135] This can guide staff to make reasonable selections of multiple units in a multi-unit air conditioning system, thereby avoiding abnormal system operation due to unreasonable selection settings.

[0136] Based on the same technical concept, embodiments of this application also provide a guidance information generation device, such as... Figure 6 As shown, the device includes:

[0137] The acquisition module 601 is used to acquire the operation strategy table corresponding to the multi-unit air conditioning system, wherein the operation strategy table contains multiple unit combinations and the combination parameters corresponding to each unit combination;

[0138] The display module 602 is used to display the operation strategy table through a visualization component, and to receive strategy modification information based on the operation strategy table through the visualization component;

[0139] The judgment module 603 is used to judge the rationality of the policy modification information based on the preset policy restriction rules and the combined parameters, and obtain the corresponding judgment result.

[0140] The generation module 604 is used to generate corresponding modification guidance information based on the determination result, so as to instruct the user to modify the operation strategy table based on the modification guidance information to obtain the target operation strategy table.

[0141] In this embodiment, firstly, an operation strategy table corresponding to a multi-unit air conditioning system is obtained. This table includes various unit combinations and corresponding combination parameters for each combination.
