[0037] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0039] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0040] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0041] Existing modular air conditioning units primarily rotate compressors based on conditions such as water temperature, load, cumulative compressor lifespan, fault priority, and energy savings. While a silent mode is already available within the unit's control logic, this typically operates by reducing the operating frequency of the compressor and fan, limiting the overall unit load and failing to effectively leverage the multi-module nature to balance noise and load.

[0042] With regard to the problem in the related art that modular air-conditioning units make excessive noise during operation and that reducing the noise affects the load of the entire unit, no effective solution has been proposed so far.

[0043] The embodiments of the present invention provide a compressor scheduling method, device and modular air-conditioning unit to at least solve the problem in the related art that the modular air-conditioning unit makes excessive noise during operation and that reducing the noise affects the load of the entire unit.

[0044] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] This embodiment provides a compressor scheduling method for a modular air conditioning unit. The modular air conditioning unit includes at least two modules (also referred to as modular units), each of which includes at least one compressor. The modular air conditioning unit is composed of at least two modular units and is centrally scheduled and operated by a controller. Multiple modular units are placed in the same space at regular intervals. The arrangement can be based on pre-defined rules or customized to meet customer requirements.

[0047] FIG1 is a flow chart of a compressor scheduling method provided in Example 1 of the present invention. As shown in FIG1 , the method includes the following steps:

[0048] S101, determining the load range of the load demand of the unit.

[0049] S102 , turning on the controlled objects according to the position arrangement of the controlled objects and the load range, in a principle of avoiding resonance between adjacent controlled objects, wherein the controlled objects include modules and / or compressors.

[0050] S103: Adjust the frequency of the turned-on compressor according to the load demand, and monitor the noise so that the noise is less than a noise threshold corresponding to the load range.

[0051] Specifically, at least one load threshold can be pre-set based on the actual situation of the unit, and different load ranges can be divided according to the load threshold. Different load ranges correspond to different noise thresholds.

[0052] According to the actual situation of the unit or the control logic of the unit, the control object can be a module, a compressor, or a module and a compressor.

[0053] This embodiment turns on the control objects based on the load range of the unit's load demand and the positional arrangement of the control objects, with the principle of avoiding resonance between adjacent control objects. The frequency of the activated compressors is then adjusted based on the load demand, and noise is monitored to ensure that the noise is below the noise threshold corresponding to the load range. The operation of the compressors in the modular air-conditioning unit is controlled by positional arrangement to avoid resonance between adjacent compressors, resulting in lower overall unit noise. Compressor rotation is scheduled based on both noise and load demand, fully leveraging the advantages of multiple modules to reduce overall operating noise and ensure a balance between noise and operating load in the modular air-conditioning unit. This allows each compressor to maximize its maximum operating life under its respective operating conditions, resolving the problem in related technologies of excessive noise during modular air-conditioning unit operation and the impact of noise reduction on the overall unit load.

[0054] In one embodiment, the control objects are turned on based on the position arrangement of the control objects and the load range, with the principle of avoiding resonance between adjacent control objects, including: determining the number of control objects that need to be turned on based on the load range; determining the control objects that need to be turned on and the order in which they are turned on based on the position arrangement of the control objects, wherein control objects that are not adjacent to each other are turned on first, and then the adjacent control objects that have been turned on are turned on in ascending order of number; and turning on the control objects based on the load demand.

[0055] For modular air-conditioning units, experiments can be conducted to determine the load corresponding to turning on different numbers of control objects while maintaining an appropriate noise level. This can be used as the load threshold, so that different load ranges will correspond to the approximate number of control objects that need to be turned on. However, the specific control objects turned on should still be based on meeting load requirements and reducing noise.

[0056] For any control object, the more adjacent control objects that are turned on, the greater the possibility of resonance caused by turning on the control object. Therefore, in this embodiment, when all non-adjacent control objects have been turned on, the control object with the smallest number of adjacent control objects that are turned on is preferentially turned on, so as to avoid resonance as much as possible and reduce noise.

[0057] This embodiment determines the control objects that need to be turned on based on their positional arrangement, which can reduce the unit noise as much as possible.

[0058] Furthermore, based on the positional arrangement of the control objects, the control objects to be activated and their activation order are determined, including: when each module includes at least two compressors, using the module as the control object to determine the module to be activated, and all compressors within the module are activated and deactivated simultaneously; or, first using the module as the control object to determine the module to be activated, and then using the compressor as the control object to determine the compressor to be activated within the module; or, regardless of the correspondence between the module and the compressor, directly using the compressor as the control object to determine the compressor to be activated, that is, ignoring the module and treating the compressor as an independent scheduling object. In addition, when each module includes only one compressor, using the module as the control object is equivalent to using the compressor as the control object.

[0059] This embodiment can determine the control object according to actual control requirements, thereby better performing compressor scheduling.

[0060] Specifically, turning on the control objects according to the load demand includes: directly turning on all control objects that need to be turned on according to the load demand; or, based on the on / off status of the current control objects, first turning on one control object in the turning-on order, adjusting its frequency, and if the unit output still does not meet the load demand, turning on another control object, and repeating this cycle until all control objects that need to be turned on are turned on or until the unit output meets the load demand. Different control demands can be met in this way.

[0061] In one embodiment, the frequency of the activated compressors is adjusted based on the load demand, and noise is monitored to ensure that the noise is below a noise threshold corresponding to the load range. This includes: if the unit output does not meet the load demand, increasing the frequency of the activated compressors; and simultaneously monitoring the noise of each detection object to ensure that the noise of each detection object is below the noise threshold corresponding to the load range, where the detection object is a single module, a single compressor, or at least two adjacent compressors. This embodiment can ensure that the unit noise is at an appropriate level while meeting the load demand during operation.

[0062] At least one sound sensor is installed corresponding to each detection object to monitor the noise of the detection object.

[0063] Before monitoring the noise of each test object, the system also binds the location, noise level, compressor on / off status, and compressor frequency of each test object. This information can be recorded in a table or array format. This binding facilitates access to this information and facilitates rapid scheduling and control.

[0064] Example 2

[0065] This embodiment, based on the above-described embodiment 1, provides a specific example of a compressor scheduling method, which will be described below with reference to the accompanying drawings. However, it should be noted that this specific example is intended solely to better illustrate the present application and does not constitute an undue limitation of the present application. Explanations of terms that are identical or corresponding to those in the above-described embodiment will not be repeated in this embodiment.

[0066] Figure 2 shows the layout of a modular air conditioning unit. The unit consists of eight modules, which are regularly spaced and arranged within a single space. The modules must be arranged according to pre-defined rules, such as in a single or multiple rows. In some cases, custom placement can be achieved. The controller includes a device for inputting relevant position data, such as a touch screen.

[0067] Assuming each module contains a compressor, each module is considered a sound source for detection and scheduling. At least one sound sensor within each module detects noise levels. A controller acquires sound sensor data from all modules, allowing the noise level and location data for each module to be linked.

[0068] Figure 3 shows a schematic diagram of the modular air conditioning system's noise and module position binding. Noise data is collected for a total of eight modules, with modules 1 through 8 corresponding to noise levels of X1 through X8 (dB). The controller records the noise of each module according to the arrangement shown in Figure 3. Its position can be represented by a two-dimensional array. Each element in the two-dimensional array can contain the module's noise level data, compressor on / off status data, compressor operating frequency data, and so on. This effectively binds the module's noise level data to its placement within the controller.

[0069] FIG4 is a flowchart of compressor scheduling rotation for a noise-based modular air-conditioning unit. The flowchart is based on the modular air-conditioning unit shown in FIG3 and includes the following steps:

[0070] S401, power on starts.

[0071] S402, determine whether the load demand of the unit is less than Y1, if so, go to S403, if not, go to S405.

[0072] S403, start the compressor in the order of modules 1, 3, 6, and 8.

[0073] S404: Control the noise to be less than Z1. Then return to S402 to continue the determination.

[0074] S405, determine whether the load demand of the unit is less than Y2, if so, go to S406, if not, go to S408.

[0075] S406, modules 1, 3, 6, and 8 keep the compressors turned on.

[0076] S407: Control the water temperature by operating frequency to meet the load requirement, and control the noise to be less than Z2. Then return to S402 to continue the determination.

[0077] S408, determine whether the load demand of the unit is less than Y3, if so, go to S409, if not, go to S412.

[0078] S409, modules 1, 3, 6, and 8 keep the compressors turned on.

[0079] S410, start the compressor in the order of modules 4, 5, 2, and 7.

[0080] S411: Control the water temperature by operating frequency to meet the load requirement, and control the noise to be less than Z3. Then return to S402 to continue the determination.

[0081] S412, keep all compressors on.

[0082] S413: Control the water temperature by operating frequency to meet the load requirement, and control the noise to be less than Z4. Then return to S402 to continue the determination.

[0083] Y1 represents the first load threshold, Y2 represents the second load threshold, and Y3 represents the third load threshold. Y1 < Y2 < Y3. Z1 represents the first noise threshold, Z2 represents the second noise threshold, Z3 represents the third noise threshold, and Z4 represents the fourth noise threshold. There is no clear relationship between the noise thresholds Z1, Z2, Z3, and Z4. The noise thresholds must be determined during development through experimental measurements of the noise level of the entire modular air conditioning unit and based on the number of powered modules.

[0084] Of course, in actual applications, more load thresholds can be set according to the actual situation of the unit to divide more load ranges, and the noise threshold will also be subdivided to achieve a smaller noise level for the entire unit.

[0085] When the load of the entire modular air-conditioning unit is less than Y1, the modules separated by position (i.e., non-adjacent) are turned on first, and the operating frequency of the compressor is controlled so that the module noise is less than the corresponding noise threshold Z1. Referring to Figure 3, modules 1, 3, 6, and 8 can be turned on in sequence, or modules 2, 4, 5, and 7 can be turned on in sequence. For example, if module 1 is turned on and the water temperature does not meet the requirement, module 3 is turned on. If the water temperature still does not meet the requirement, module 6 is turned on. If the water temperature still does not meet the requirement, module 8 is turned on. In this example, the value of Y1 corresponds to the total load of the four modules when the compressors of the four modules are turned on and the noise is at the operating frequency of Z1, that is, Y1 is the load when the compressors of the four modules are turned on to a suitable noise level. If the water temperature exceeds the set value, the compressors of the corresponding modules will be turned off in the opposite order of the above (e.g., in the order of modules 8, 6, 3, and 1). Considering that the compressors generally run at a lower initial frequency under low load conditions and cannot be reduced in frequency, the compressors are turned off directly.

[0086] When the load of the entire modular air conditioning unit is between Y1 and Y2 (i.e., Y1 ≤ Load < Y2), modules 1, 3, 6, and 8, or modules 2, 4, 5, and 7, are turned on. The noise level of the four modules turned on at this time must be less than Z2. It is understood that the operating frequencies of these four modules can be adjusted within a certain range while keeping the noise level less than Z2. Therefore, the water temperature can be controlled by adjusting the operating frequencies of these four modules.

[0087] When the load of the entire modular air conditioning unit is between Y2 and Y3 (i.e., Y2 ≤ Load < Y3), this load generally requires multiple compressors to be turned on to meet the requirements. In addition to keeping already enabled modules running, you can also turn them on in the order of module 4, module 5, module 2, and module 7 (since the number of adjacent enabled modules to modules 4 and 5 is less than the number of adjacent enabled modules to modules 2 and 7, turning on modules 4 and 5 first will minimize the impact of resonance). Simultaneously, control the operating frequency of each enabled module so that the noise level is less than Z3.

[0088] When the load of the entire modular air-conditioning unit is greater than or equal to Y3, all module compressors generally need to be turned on to meet the load demand. The water temperature is controlled by adjusting the operating frequency of each compressor. At the same time, the noise of each module compressor during operation is less than the threshold Z4.

[0089] All compressors within a module can be used as a single element for noise detection and scheduling. All compressors within a module can be started and stopped simultaneously, effectively controlling a single module. This simplifies control logic. Multiple compressors within a module can also be started and stopped based on their respective positions, according to overall control logic requirements and noise levels. This reduces overall noise levels while improving control accuracy.

[0090] To reduce the number of sound sensors, it's not necessary to install a sound sensor on every compressor. Instead, one sensor can be installed between every two adjacent compressors, or between every four adjacent compressors. These two or four compressors can be used as a single control element for noise detection and scheduling. Modules can then be rotated using other scheduling principles.

[0091] This embodiment controls the operation of the compressors in the modular air-conditioning unit according to the position arrangement to avoid resonance between adjacent compressors and make the noise of the whole machine smaller; the compressor rotation scheduling is carried out based on the noise and load requirements, and the advantages of multiple modules are fully utilized to make the overall operation noise lower, thereby ensuring the balance between the noise and operating load of the modular air-conditioning unit, and being able to give full play to the maximum operating life of each compressor under its respective working conditions, thereby solving the problem in the related art that the modular air-conditioning unit makes too much noise during operation and that reducing the noise will affect the load of the whole machine.
