When there is an indoor unit of an air conditioner of another refrigerant system that is not intermittently operated by a compressor in an air-conditioning target region in which the indoor unit of the air conditioner is provided, intermittent operation suppression control is performed in which the operation of the indoor unit is continued and the compressor that is intermittently operated is brought into a stopped state.

Description

Technical Field

[0001] This disclosure relates to air conditioning control systems, etc. Background Technology

[0002] Regarding the control of the number of air conditioners, the technology described in Patent Documents 1 and 2 is known, for example. That is, Patent Document 1 describes "as the indoor air conditioning load increases, the number of outdoor units operated by the outdoor unit operation control unit (41) is increased".

[0003] Furthermore, Patent Document 2 discloses an air conditioning control system comprising: an acquisition unit that acquires parameters related to the operation of a compressor; and a determination unit that determines the number of operating air conditioners among the plurality of air conditioners based on the parameters acquired by the acquisition unit for each of the plurality of air conditioners.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2013-24465

[0005] Patent Document 2: Japanese Patent Application Publication No. 2022-89489 Summary of the Invention

[0006] In the technologies described in Patent Documents 1 and 2, as mentioned above, the number of air conditioners in operation is adjusted based on parameters related to indoor air conditioning load and compressor operation, but there is room for further energy saving.

[0007] Therefore, the subject of this disclosure is to provide an air conditioning control system that appropriately regulates the air and achieves energy saving.

[0008] To address the aforementioned problem, the air conditioning control system disclosed herein includes a controller for controlling multiple air conditioners, each of which has its own refrigerant system. When an air conditioner among the multiple air conditioners operates intermittently via a compressor, and an indoor unit of another air conditioner with a refrigerant system that does not operate intermittently via a compressor is present in the air conditioning target area where that air conditioner's indoor unit is located, the controller performs intermittent operation suppression control. This intermittent operation suppression control allows the operation of that indoor unit to continue, and stops the compressor that was operating intermittently.

[0009] According to this disclosure, an air conditioning control system that can properly regulate the air and achieve energy saving can be provided. Attached Figure Description

[0024] Implementation Method

[0025] Figure 1 This is a structural diagram of an air conditioning control system X1 that includes implementation methods.

[0026] The air conditioning control system X1 is a system that controls multiple air conditioners. Additionally, in... Figure 1 The diagram is simplified, but the multiple air conditioners controlled by the controller 100 each have an outdoor unit and one or more indoor units connected to the outdoor unit via refrigerant piping (see reference). Figure 2 In other words, multiple air conditioners each have their own refrigerant system. Such air conditioners can be configured as so-called multi-split air conditioners (VRF: Variable Refrigerant Flow), or as commercial air conditioners, or other types of air conditioners. Furthermore, multiple types of air conditioners can also coexist. Air conditioning applications for multiple air conditioners include, in addition to offices and shops, commercial facilities, factories, plantations, and warehouses.

[0027] like Figure 1 As shown, the air conditioning control system X1 is configured to include a controller 100 (air conditioning control device) and a service server 200. The controller 100 has the functions of managing information from multiple air conditioners and controlling multiple air conditioners. Although not shown in the diagram, the controller 100's hardware structure includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and various interfaces and other electronic circuits. Furthermore, the CPU reads the program stored in the ROM, expands it in the RAM, and executes various processes.

[0028] The business server 200 is a server that provides predetermined information to the controller 100, and is connected to the controller 100 via the wide area network N1.

[0029] As will be described in detail later, in this embodiment, the intermittent operation of the compressor is suppressed by the control of the controller 100. This is because starting the compressor from a stopped state requires a large amount of electricity, and if the compressor's operation / stopping is repeated at a high frequency, it consumes more electricity compared to the case of continuous compressor operation.

[0030] For example, suppose that some of the multiple air conditioners used to air-condition a designated area are operating intermittently. In this case, when the intermittently operating air conditioner is stopped, the air conditioning load on the remaining air conditioners increases, and their power consumption increases accordingly. However, the total power consumption of all air conditioners, including the one that stopped intermittent operation, decreases. As a result, the overall operating efficiency of the system can be improved.

[0031] In addition, sometimes a single air conditioner is used to provide air conditioning for a designated area. If the compressor in this air conditioner is running intermittently, stopping it would violate the user's intention to provide air conditioning (cooling or heating) for the area being treated. In such cases, it is undesirable to stop the intermittently running compressor.

[0032] Therefore, in this embodiment, if there is an indoor unit (operating indoor unit) of an air conditioner with another refrigerant system that is not operating intermittently in the air-conditioned area where the air conditioner is operating intermittently via the compressor, the operation of that indoor unit continues, and the compressor that is operating intermittently stops. By performing such "intermittent operation suppression control" by the controller 100, air conditioning in the air-conditioned area can continue, and operating efficiency can be improved.

[0033] Figure 1 The controller 100 shown includes a direct communication IF unit 11 and a general communication IF unit 12 for communication with the air conditioner. Furthermore, the term "IF" in the above description is an abbreviation for "Interface". The direct communication IF unit 11 and the general communication IF unit 12 are communication interfaces used to obtain operating status information of the air conditioner connected to them or to transmit control signals to the air conditioner.

[0034] The direct communication IF unit 11 communicates in a predetermined manner with air conditioners manufactured by the same company as its controller 100 (referred to as air conditioners manufactured by this company). The general communication IF unit 12 communicates in a predetermined manner via repeater 30 with air conditioners manufactured by different companies than its controller (referred to as air conditioners manufactured by other companies). Additionally, in Figure 1 In the diagram, outdoor / indoor units of air conditioners manufactured by other companies are shown with dots.

[0035] In addition to the structures described above, the controller 100 also includes a connection management unit 13, a layout management unit 14, a detection mode storage unit 15, an efficiency monitoring method setting unit 16, an operation status information acquisition unit 17, an intermittent operation detection unit 18, an air conditioner stop decision unit 19, an operation recovery decision unit 20, a measuring instrument IF unit 21, and a total power acquisition ratio distribution unit 22.

[0036] The Connection Management Department 13 manages the connection information of each air conditioner unit. Furthermore, "connection information" refers to the information of the communication interface used to determine the acquisition of operating status information and the transmission of control signals. This connection information is appropriately set by the system administrator during initial setup.

[0037] The layout management department 14 manages the predetermined layout information. Furthermore, "layout information" refers to information indicating the correspondence between the air-conditioned area and the indoor units of each air conditioner. This layout information is appropriately set by the system administrator during initial setup.

[0038] The detection mode storage unit 15 stores data on multiple detection modes for detecting outdoor units that operate intermittently via compressors. Additionally, the detection mode storage unit 15 also stores data on recovery conditions after the compressor, which operates intermittently, has stopped.

[0039] The efficiency monitoring method setting unit 16 selects, in a predetermined manner, multiple detection methods and recovery conditions stored in the detection method storage unit 15 based on operating efficiency and other factors, the actual application of the detection method and recovery conditions.

[0040] The operation status information acquisition unit 17 obtains information indicating the operation status of the compressor, etc. from each air conditioner via a communication interface managed by the connection management unit 13.

[0041] The intermittent operation detection unit 18 determines the air conditioner that is operating intermittently via the compressor based on the information obtained by the operation status information acquisition unit 17.

[0042] If the air conditioner stop decision unit 19 determines whether to stop the compressor of an air conditioner that is operating intermittently via its compressor, it will then decide whether to stop the compressor of that air conditioner.

[0043] After the compressor, which has been operating intermittently, stops, the operation recovery decision unit 20 determines whether predetermined recovery conditions are met. If the recovery conditions are met, the operation recovery decision unit 20 outputs a control command to restart the operation of the compressor via the communication interface managed by the connection management unit 13.

[0044] The measuring unit IF 21 acquires the detection values ​​of the measuring unit 40 at every moment. The measuring unit 40 is, for example, used to detect air conditioners manufactured by other companies. Figure 1 A power meter for the outdoor unit of an air conditioner (such as air conditioner B1 with dots) is installed on a distribution panel (not shown). Alternatively, an ammeter can be used as the measuring device 40. Furthermore, in air conditioners manufactured by other companies, if the controller 100 can obtain the detected values ​​of the outdoor unit's power consumption and current, there is no need to separately install the measuring device 40.

[0045] In addition, wired communication via communication cable can be performed between the controller 100 and each air conditioner, repeater 30, and measuring device 50. Alternatively, wireless communication using Wi-Fi (registered trademark) or similar methods can also be performed.

[0046] The total power acquisition and allocation unit 22 calculates the total power consumption (time average) of multiple air conditioners as the total power consumption, and allocates (distributes) this total power consumption proportionally to each air-conditioned area. For example, the total power acquisition and allocation unit 22 acquires the power consumption of each air conditioner in real time and calculates the total power consumption as the total power consumption. Then, the total power acquisition and allocation unit 22 allocates this total power consumption proportionally based on the operating time (or heat-on time) of the indoor unit in a predetermined air-conditioned area, and calculates the power consumption of each air-conditioned area.

[0047] Alternatively, the business server 200 can also perform some or all of the functions of the controller 100. For example... Figure 1 As shown, with all the functions of the controller 100, there is no need to set up a separate business server 200.

[0048] Figure 2 This is an explanatory diagram showing the connection relationship between the controller 100 and each air conditioner.

[0049] In addition, Figure 2 In the diagram, the direct communication IF unit 11 and the general communication IF unit 12 are shown as part of the structure of the controller 100; the remaining functional units are omitted from the diagram. Additionally, in... Figure 2 In the diagram, thick solid lines represent refrigerant piping, and dashed lines represent communication lines.

[0050] exist Figure 2 In this example, eight air conditioners (1-8) manufactured by the same company as controller 100 are provided. Additionally, two air conditioners (B1 and C1) manufactured by other companies are provided. These ten air conditioners (1-8, B1, and C1) each have their own refrigerant system.

[0051] For example, air conditioner 1 is configured such that one outdoor unit o11 and three indoor units i11, i12, and i13 are connected in a predetermined manner via refrigerant piping. Outdoor unit o1 is located outdoors. Indoor units i11, i12, and i13 are located in a predetermined area for air conditioning. These outdoor units o1 and indoor units i11, i12, and i13 are connected to the direct communication IF unit 11 of controller 100 via communication lines.

[0052] Furthermore, air conditioner 1 includes a compressor 1a, an outdoor heat exchanger (not shown), an expansion valve (not shown), and an indoor heat exchanger (not shown), which are connected in a ring shape via refrigerant piping and a four-way valve (not shown). The compressor, outdoor heat exchanger, four-way valve, and outdoor fan (not shown) are all located in outdoor unit o1. Additionally, the expansion valve, indoor heat exchanger, and indoor fan (not shown) are respectively located in indoor units i11, i12, and i13. Other air conditioners 2-8, B1, and C1 have the same structure. For example, other air conditioners 2-8, B1, and C1 also have compressors 1a-8a, B1a, and C1a respectively in outdoor units o1-o8, oB1, and oC1.

[0053] Regarding the air conditioners 1-8 manufactured by our company, the controller 100 can obtain detailed data related to the operation of the compressor in real time. Therefore, in the air conditioners 1-8 manufactured by our company, for example, it can be determined whether there is intermittent operation based on predetermined timing data indicating the operation / stop of the compressor. In addition, in addition to the operating frequency of the compressor, it is also possible to determine whether there is intermittent operation based on the compressor's current value and power consumption.

[0054] On the other hand, for air conditioners B1 and C1 manufactured by other companies, adapters compatible with common communication protocols such as Bacnet (registered trademark) and ECHONET (registered trademark) should be used appropriately. Figure 2 In the example, outdoor unit oB1 is connected via Bacnet adapter 31 (and... Figure 1 The repeater 30 (corresponding to the repeater) is connected to the general communication IF unit 12. Additionally, another outdoor unit oC1 is connected via contact input device 32 (corresponding to the repeater 30). Figure 1 The repeater 30) is connected to the general communication IF section 12. For air conditioners B1 and C1 manufactured by other companies, timing data indicating compressor operation / stop is often unavailable; therefore, the controller 100 uses the measuring device 40 (see reference 40) to... Figure 1 The compressor's operation / stop is determined by the detected value.

[0055] Figure 3 This is an explanatory diagram showing an example of the layout of an area where air conditioning is applied.

[0056] also, Figure 3 The air conditioners 1-8, B1, and C1 shown are... Figure 2 The air conditioner shown corresponds to this. In Figure 3In this example, besides banks and restaurants as tenants, there are also rental activity areas and shared lobbies / corridors. Air conditioners 1-8, B1, and C1, and controller 100 are installed in such a building. Additionally, a measuring device 40 is installed on the distribution panel (not shown) in the machinery room. As described above, the measuring device 40 detects the power values ​​of the outdoor units oB1 and oC1 of the air conditioners B1 and C1 manufactured by other companies. The constantly measured values ​​from the measuring device 40 are output to the controller 100.

[0057] exist Figure 3 In the example, the shared lobby and corridors are air-conditioned by air conditioner 1. Additionally, banks with meeting rooms, windows, and offices are air-conditioned by four air conditioners 2-5. Restaurants with kitchens / customer seating are air-conditioned by three air conditioners 6-8. Event areas are air-conditioned by two air conditioners, B1 and C1, manufactured by another company.

[0058] Figure 4 This is an explanatory diagram showing an example of the connection management table 51.

[0059] Figure 4 The connection management table 51 shown is a data table used to manage the connection information of each air conditioner. This connection management table 51 is initially set by the system administrator and then managed by the connection management department 13 (see reference). Figure 1 )manage.

[0060] like Figure 4 As shown, in the connection management table 51, the "Air Conditioner ID," "Outdoor Unit," "Indoor Unit," "Information Source IF Port," and "Control IF Port" are mapped together. The "Air Conditioner ID" is the identification information assigned to each air conditioner. The "Outdoor Unit" column records the identification information of the outdoor unit of the air conditioner, determined by the Air Conditioner ID. The "Indoor Unit" column records the identification information of the indoor unit of the air conditioner, determined by the Air Conditioner ID. This identification information is set as the so-called node address. Figure 4 In the example, for simplicity, the symbols of the outdoor unit and the indoor unit (for example, the symbol of the outdoor unit o1 is "o1") are represented as identification information.

[0061] exist Figure 4 The "Information Source IF Port" field shows the port of the interface used by the controller 100 to obtain the operating status information of the air conditioner. For example, in the air conditioner 1 manufactured by our company, the interface is accessed via the direct communication IF unit 11 (see reference 100). Figure 1 The system obtains the operating status information of air conditioner 1. Additionally, for air conditioner B1 manufactured by other companies, the power meter information is obtained from the power meter port of controller 100 via meter 40 (see reference). Figure 1The measured value is obtained from the ammeter port of the controller 100 via the ammeter port of the meter 40 (see reference). For other air conditioners C1 manufactured by other companies, the measured value is obtained from the meter 40 (see reference). Figure 1 The detection value of ).

[0062] exist Figure 4 The "Control IF Port" field shown lists the ports used when the controller 100 sends control signals to each air conditioner. For example, in the air conditioner 1 manufactured by our company, the direct communication IF unit 11 of the controller 100 (see reference 11) is used to send control signals. Figure 1 The controller 100 sends control signals to outdoor unit o1 and indoor units i11, i12, and i13. Additionally, in air conditioner B1 manufactured by another company, control signals are sent to outdoor unit oB1 and indoor unit iB1 via the Bacnet adapter interface of the controller 100. Furthermore, in other air conditioner C1 manufactured by another company, control signals are sent to outdoor unit oC1 and indoor unit iC1 via the contact interface of the controller 100.

[0063] Figure 5 This is an explanatory diagram showing an example of layout management table 52.

[0064] in addition, Figure 5 The layout management table 52 shown is... Figure 3 The layout corresponds to that.

[0065] Layout management table 52 represents the area where air conditioning is applied ( Figure 3 This is a data table showing the correspondence between "areas" and "zones" and the indoor units of each air conditioner. This layout management table 52 is initially set by the system administrator and then managed by the layout management department 14 (see reference). Figure 1 )manage.

[0066] In Layout Management Table 52, "Area," "Block," and "Indoor Unit" correspond to each other. "Area" refers to the designated space encompassed by the facility where the air conditioning unit is installed. Figure 5 In the example, the "area" of the commercial facility is divided into common areas, event areas, banking areas, and restaurant areas.

[0067] A "block" is a space within a "region" that is further divided into multiple sections. Figure 5 In the example, the "blocks" included in the bank area are divided into consultation room blocks, window blocks, and office blocks. Similarly, the "blocks" included in the restaurant area are divided into customer seating blocks and kitchen blocks.

[0068] The "Indoor Units" column in Layout Management Table 52 contains identification information for indoor units configured in predetermined areas. For example, indoor units i11, i12, and i13 are configured in a shared area (see also...). Figure 3 In addition, indoor units iB1 and iC1 are installed in the activity area (see also...). Figure 3 In this way, indoor units configured in a predetermined area or block are registered as a group. Thus, controller 100 (see reference) Figure 3 It can determine which indoor unit will be used for air conditioning in a specific area. Additionally, in Figure 5 In the example, the indoor units are grouped into two stages: "region" and "block". However, the number of stages when grouping can be changed appropriately.

[0069] Figure 6 This is an explanatory diagram showing an example of the detection method registration form 53.

[0070] Figure 6 The test method registration form 53 shown is a data table indicating the test methods when testing an outdoor unit that operates intermittently via a compressor, and is stored in the test method storage unit 15 (see reference). Figure 1 In ) Figure 6 In the example, three detection methods are registered: method α, method β, and method γ. Additionally, in the detection method registration table 53, "method" corresponds to "detection algorithm." "Method" is the name (or identification information) attached to the detection method for intermittent compressor operation. "Detection algorithm" is the algorithm used to detect intermittent compressor operation using a predetermined detection method.

[0071] Furthermore, when the compressor is used for intermittent operation, the compressor's operation and shutdown occur alternately and repeatedly within a relatively short period of time. Therefore, in modes α, β, and γ, the frequency of compressor operation and shutdown is used to determine whether intermittent operation exists.

[0072] In mode α, if the compressor operates / stops repeatedly more than a predetermined number of times (e.g., more than twice) within a certain time period (e.g., 30 minutes), it is determined that the compressor is operating intermittently.

[0073] In mode β, if the time from the start of compressor operation to its stop is shorter than the predetermined time (e.g., less than 20 minutes), it is determined that the compressor is operating intermittently.

[0074] In mode γ, if the operating duration of the compressor is longer than the duration of the stopped state, it is determined that the compressor is operating intermittently.

[0075] In this embodiment, among the three detection methods (methods α, β, and γ) shown in the detection method registration table 53, the efficiency monitoring method setting unit 16 (see reference 53) sets the method accordingly. Figure 1 Select a predetermined testing method for each air conditioner. The method for selecting the testing method will be described later.

[0076] Figure 7 This is an explanatory diagram showing an example of the recovery condition registration form 54.

[0077] Figure 7 The recovery condition registration table 54 shown is a data table indicating the recovery conditions when the compressor is restarted after intermittent operation has stopped. Figure 7 In the example, as four recovery conditions, conditions K, L, M, and N are registered.

[0078] Condition K refers to the situation where, in an air-conditioned area including an air conditioner whose compressor has been intermittently stopped, the compressor, which was temporarily stopped, is resumed to operation when the remote control (not shown) is operated in a manner that enhances air conditioning. Here, "enhanced air conditioning" means lowering the set temperature by operating the remote control during cooling operation, or raising the set temperature by operating the remote control during heating operation.

[0079] Condition L is established when, after stopping the intermittently operating compressor, the temperature in the air-conditioned area containing the compressor changes by a predetermined value or more, the temporarily stopped compressor is restarted. For example, when the air conditioner is operating in cooling mode in a predetermined air-conditioned area, if, after stopping the intermittent operation of the air conditioner, the temperature in that air-conditioned area exceeds a predetermined value from the time the intermittent operation stopped, the controller 100 restarts the temporarily stopped compressor. Conversely, for example, when the air conditioner is operating in heating mode in a predetermined air-conditioned area, if, after stopping the intermittent operation of the air conditioner, the temperature in that air-conditioned area decreases by a predetermined value or more from the time the intermittent operation stopped, the controller 100 restarts the temporarily stopped compressor.

[0080] Condition M is to restore the temporarily stopped compressor to operation after a predetermined time has elapsed since the moment the intermittently operating compressor was stopped.

[0081] Condition N is when the total power consumption P0 (time average) during intermittent compressor operation is less than the total power consumption P1 (time average) after the compressor stops (P0 < P1), the temporarily stopped compressor is restarted. Furthermore, the total power consumption P0 and P1 can be the power consumed by the air-conditioned area proportionally allocated to the intermittently operating air conditioner, or the total power consumption of all air conditioners. In this embodiment, the efficiency monitoring method setting unit 16 (see the recovery condition registration table 54) uses one of the four conditions K, L, M, N shown in the recovery condition registration table 54. Figure 1 The pre-selected conditions.

[0082] Figure 8 This is an explanatory diagram of an example of the representation method selection in Table 55.

[0083] Figure 8 The method selection table 55 shows the detection method for intermittent compressor operation for each air conditioner (refer to...). Figure 6 ) and the recovery conditions for the compressor to return from a stopped state to operation (refer to Figure 7 A data table combining (e.g., ...). Figure 8 As shown in Table 55, match the “Air Conditioner ID”, “Detection Method” and “Recovery Condition”.

[0084] "Air conditioner ID" is the identification information assigned to each air conditioner.

[0085] "Detection method" refers to the method (approach) used to detect whether the compressor is operating intermittently. In this embodiment, this is determined from Detection Method Registration Table 53 (see...). Figure 6 Among the three methods α, β, and γ, the "testing method" is selected for each air conditioner individually.

[0086] "Resumption conditions" are the conditions under which a compressor, after being stopped from intermittent operation, is restored to its original operating state. In this embodiment, these conditions are found in the recovery condition registration table 54 (see...). Figure 7 Choose one or more of the four conditions K, L, M, and N. Furthermore, when multiple conditions are selected, they can be appropriately combined with either AND or OR conditions.

[0087] For example, regarding air conditioner 1, intermittent operation of the compressor is automatically detected according to method α. Specifically, if the compressor's operation / stopping repeats more than twice within 20 minutes, the controller 100 determines that intermittent operation of the compressor is occurring. Then, if a predetermined time has elapsed since the moment the intermittently operating compressor stopped (condition M), and a predetermined operation such as enhanced air conditioning is performed via remote control (condition K), the controller 100 resumes operation of the temporarily stopped compressor. Descriptions for the remaining air conditioners 2 to 10 are omitted, but the intermittent operation detection method and subsequent recovery conditions are set for each.

[0088] Furthermore, the optimal detection method and subsequent recovery conditions for the intermittent operation of the compressor often vary depending on the air conditioner, and the optimal detection method and recovery conditions are often unclear during initial settings. In such cases, the efficiency monitoring method setting unit 16 (see reference) Figure 1 Try the detection methods and recovery conditions in turn to determine the best combination.

[0089] For example, efficiency monitoring method setting unit 16 (see reference) Figure 1 The initial setting is mode α for all air conditioners. For example, the efficiency monitoring method setting unit 16 is set to determine intermittent operation when the compressor's operation / stop occurs more than twice within 30 minutes. Based on this mode α, which detects intermittent compressor operation, the efficiency monitoring method setting unit 16 uses mode α as the detection method when operating efficiency is improved by implementing intermittent operation suppression control. Furthermore, based on the intermittent operation state, the efficiency monitoring method setting unit 16 appropriately optimizes the time threshold and the threshold for the number of operation / stop cycles used in mode α.

[0090] Furthermore, the aforementioned operating efficiency can also be calculated based on the overall system power consumption (time average) calculated by the total power acquisition ratio allocation unit 22. Alternatively, the operating efficiency can also be calculated based on the power consumption (time average) proportionally allocated to the air-conditioned area of ​​the intermittently operating air conditioner.

[0091] After detecting intermittent operation of the air conditioner in mode α, if the operating efficiency is not high even with intermittent operation suppression control, the efficiency monitoring method setting unit 16 switches the intermittent operation detection method to mode β for that air conditioner. Mode α is the simplest detection method, but intermittent operation suppression control begins after a predetermined number of compressor start / stop cycles. In contrast, in mode β, the presence or absence of intermittent operation is determined based on the operating duration when the compressor switches from a stopped state to an operating state, thus enabling the detection of intermittent operation in a shorter time compared to mode α. When intermittent compressor operation is detected based on mode β, and operating efficiency is improved by implementing intermittent operation suppression control, the efficiency monitoring method setting unit 16 adopts mode β as the detection method.

[0092] Furthermore, after detecting intermittent operation of a predetermined air conditioner using mode β, if the operating efficiency is not high even with intermittent operation suppression control, the efficiency monitoring method setting unit 16 switches the intermittent operation detection method to mode γ for that air conditioner. For example, if intermittent operation suppression control is performed in cases of intermittent operation where the compressor runs for a long time and stops for only a very short time, the air conditioning load on other operating air conditioners may become too high. In such cases, the efficiency monitoring method setting unit 16 detects whether intermittent operation exists based on mode γ.

[0093] In this way, if the controller 100 detects intermittent operation in a predetermined detection method among the multiple detection methods (e.g., mode α, β, γ) used in the detection of intermittent operation of the compressor, and the operating efficiency does not increase even if intermittent operation suppression control is performed, it will try other detection methods.

[0094] Regarding recovery conditions, for example, they can also be based on user actions via an input device (not shown), from recovery condition registration form 54 (see...). Figure 7 Choose appropriately. Alternatively, the user can set new recovery conditions in the recovery condition registration table 54 via the input device, and then apply these new recovery conditions to the mode selection table 55 (see...). Figure 8 In this embodiment, if the user does not specifically specify the recovery conditions, the compressor, which is the object of intermittent operation suppression control, is restored to operation when both conditions K and M are met. Furthermore, the recovery conditions can be appropriately changed by the efficiency monitoring method setting unit 16.

[0095] Figure 9 This is a flowchart illustrating the controller's processing flow (also refer to...). Figure 1 , Figure 2 ).

[0096] In addition, Figure 9 At the "start" time, through air conditioners 1~8, B1, C1 (refer to...) Figure 2 The air conditioning system will be operated according to the pre-set schedule.

[0097] In step S101, the controller 100 determines whether it is timed to acquire data for operating status information by the operating status information acquisition unit 17. Furthermore, the data acquisition timing refers to the time (for example, every minute) at which the controller 100 acquires predetermined operating status information from the air conditioners 1-8, B1, C1, and the measuring instrument 40, which is preset.

[0098] If the data acquisition timing is not met in step S101 (S101: No), the controller 100 repeats the processing of step S101. Alternatively, if the data acquisition timing is met in step S101 (S101: Yes), the controller 100 proceeds to step S102.

[0099] In step S102, the controller 100 obtains the operating status information of the air conditioner through the operating status information acquisition unit 17. More specifically, the controller 100 refers to the connection management table 51 (see...). Figure 4 The system obtains the operating status information of the compressors of each air conditioner through a predetermined information source IF port. In addition to the compressor operating status information, it can also obtain the air conditioner's operating mode, set temperature, and sensor detection values ​​(room temperature, outside temperature, humidity, etc.).

[0100] In step S103, the controller 100 updates the timing data through the operation status information acquisition unit 17. For example, as with an air conditioner manufactured by our company, when timing data indicating the operation / stop of the compressor is obtained as operation status information, the controller 100 updates the timing data to the latest data.

[0101] Figure 10 This is an explanatory diagram of timing data 61 representing the operation / stop of the compressor.

[0102] Figure 10 The timing data 61 shown represents the timing data for the operation / stop of the compressor in each air conditioner. Figure 10 In the example, a value of "1" is assigned when the compressor is running, and a value of "0" is assigned when the compressor is stopped. Regarding air conditioners manufactured by our company, the value is determined based on the time indicated by the compressor's operation / stop (in...). Figure 10 In the example, the data is collected every minute, generating time-series data 61. On the other hand, regarding air conditioners manufactured by other companies, as mentioned above, data indicating compressor operation / stopping is mostly unavailable. Therefore, regarding air conditioners manufactured by other companies, for example, data from measuring device 40 (refer to...) Figure 1 ) to obtain the next Figure 11 The data shown illustrates the power (or current) consumption at every moment.

[0103] Figure 11 This is an example of data showing the progression of power consumption by the outdoor unit.

[0104] also, Figure 11 The horizontal axis represents time, and the vertical axis represents the power consumption (instantaneous value) of the outdoor unit. Figure 11 During the period shown (12:00~16:00), no intermittent operation suppression control was implemented, resulting in frequent fluctuations in the outdoor unit's power consumption. This data is from air conditioners B1 and C1 manufactured by other companies (see reference). Figure 2 The measuring instrument 40 (refer to) Figure 1 ) obtained.

[0105] Figure 11 The threshold shown by the dashed line is a preset threshold for determining whether the compressor is running or stopped, representing the power (or current) consumption. Furthermore, since almost all of the outdoor unit's power consumption comes from the compressor, the average time of power consumption during compressor-stopped operation can also be set as follows: Figure 11 The threshold.

[0106] For example, if the instantaneous value of power (or current) consumption exceeds a predetermined threshold, the controller 100 determines that the compressor is operating. Conversely, if the instantaneous value of power (or current) consumption is less than the predetermined threshold, the controller 100 determines that the compressor is stopped. Then, based on the comparison between the power consumption at each moment and the threshold, the controller 100 transforms the result into a... Figure 10 The same format of time-series data. The processing (updating processing) for generating this time-series data is... Figure 9 Step S103.

[0107] Next, in step S104, the controller 100 performs predetermined calculations related to the determination of intermittent operation of the compressor via the intermittent operation detection unit 18. For example, in the mode selection table 55 (refer to...) Figure 8 The detection method for method α is specified in (see) Figure 6 In the case of [the above], the controller 100 calculates the number of times the compressor has started / stopped within the most recent predetermined time period.

[0108] In step S105, the controller 100 determines whether a compressor is operating intermittently via the intermittent operation detection unit 18. That is, for the air conditioner manufactured by this company, the controller 100 determines the compressor's operation / stop based on timing data 61 (refer to...) indicating the compressor's operation / stop. Figure 10 The controller 100 determines whether a compressor is operating intermittently. Additionally, for air conditioners from other companies included in the multiple air conditioner units, the controller 100 uses a measuring device 40 (see reference 40) to determine if a compressor is operating intermittently. Figure 1 The system obtains the power (or current) consumption of the outdoor unit and uses this value to determine whether the compressor of the outdoor unit is running intermittently.

[0109] In step S105, if there is no intermittently operating compressor in the predetermined air conditioner (S105: No), the controller 100 proceeds to step 109. Conversely, if in step S105 there is an intermittently operating compressor in the predetermined air conditioner (S105: Yes), the controller 100 proceeds to step 106. Furthermore, although in Figure 9 The information is omitted, but the intermittent operation detection unit 18 notifies the stop air conditioner determination unit 19 of the identification information (i.e., air conditioner ID) of the air conditioner containing the compressor that is intermittently operating. This identification information is used to calculate the number of air conditioners in operation (S106).

[0110] In step S106, the controller 100, through the stop air conditioner determination unit 19, determines the number of air conditioners operating in the air conditioning target area (including the number of intermittently operating air conditioners) within the air conditioning target area where air conditioners operate intermittently via compressors. Specifically, the controller 100 first refers to the layout management table 52 (see...). Figure 5 The controller 100 identifies the air conditioning target area where an air conditioner operates intermittently via a compressor. Furthermore, based on the latest operating status information, the controller 100 determines whether there is an indoor unit of another air conditioner operating (not intermittently operating, but normally operating) in that air conditioning target area.

[0111] For example, suppose that during the process Figure 3 The air conditioner 1 in the shared area shown operates intermittently. In this case, no other indoor units of the air conditioner are installed in the shared area; therefore, the number of operating air conditioners in the shared area is 1.

[0112] Additionally, for example, suppose in Figure 3 The air conditioner B1, which provides air conditioning in the activity area shown, operates intermittently. In this case, an indoor unit iC1 of another air conditioner C1 is installed in the activity area. Therefore, when the compressor of air conditioner C1 is running, the number of operating air conditioners is 2 (air conditioners B1 and C1). Conversely, when the compressor of air conditioner C1 is stopped, the number of operating air conditioners is 1 (air conditioner B1).

[0113] Furthermore, when an air conditioner with multiple indoor units is used to cool multiple air-conditioned areas, the following determination is made. For example, assuming... Figure 3 The air conditioner 6 in the restaurant area shown is operating intermittently. In this case, the indoor unit i61 of the air conditioner 6 is located in the customer seating area, while the other indoor unit i62 is located in the kitchen area.

[0114] Assuming indoor unit i61 is stopped, and other indoor units i62 are operating, only air conditioner 6 is operating in the kitchen area. Therefore, the number of air conditioners operating in the kitchen area is 1. Furthermore, even if both indoor units i61 and i62 are operating, the number of air conditioners operating in the kitchen area is still 1.

[0115] Furthermore, when multiple indoor units of the predetermined air conditioner are installed in multiple air-conditioned areas (e.g., customer seating area and kitchen area), the number of operating units in step S106 is determined based on the condition where the number of operating air conditioners in each air-conditioned area is minimized. For example, regarding... Figure 3 Air conditioner 6, which has indoor unit i61 installed in the customer seating area, has 3 operating units (air conditioners 6, 7, and 8). In addition, the air conditioner 6 installed in the kitchen area has 1 operating unit (air conditioner 6 only). In this case, in the processing of step S106, the number of operating units of air conditioner 6 is determined to be "1".

[0116] In step S107, the controller 100 determines, via the air conditioner stop determination unit 19, whether the number of operating air conditioners (including those operating intermittently) is two or more. That is, the controller 100 determines whether, in each air-conditioned area where the intermittently operating air conditioners are located, there is at least one indoor unit of another air conditioner that is not operating intermittently but is normally operating. If, in step S107, the number of operating air conditioners is two or more (S107: Yes), the controller 100 proceeds to step S108.

[0117] In step S108, the controller 100 outputs a stop command to the compressor that is operating intermittently. That is, the controller 100 refers to the connection management table 51 (refer to...). Figure 4 The controller 100 outputs a stop command to the intermittently operating compressor via a predetermined control IF port. Thus, when an air conditioner operating intermittently via its compressor exists among multiple air conditioners (S105: Yes), and when an indoor unit of another refrigerant system air conditioner that does not operate intermittently via its compressor exists in the air-conditioned area where that air conditioner's indoor unit is installed (S107: Yes), the controller 100 executes intermittent operation suppression control (S108) to continue the operation of that indoor unit and to stop the intermittently operating compressor.

[0118] Furthermore, when the indoor unit is operating in cooling mode, the controller 100 can stop the intermittently running compressor and switch the operating mode to fan-only mode. This is because, through fan-only mode, the cool air blown out from other operating indoor units is moderately agitated. Additionally, when the indoor unit is operating in heating mode, the controller 100 can also stop the intermittently running compressor, thereby stopping the indoor unit as well. This prevents the unnecessary agitation of hot air in a room that has become warm due to the operation of other air conditioners.

[0119] In addition, although Figure 9 The details are omitted, but if the compressor, which is operating intermittently, stops (S108), the suppression control management table 56 (described later) should be updated appropriately (see reference). Figure 12 ).

[0120] Furthermore, if the number of operating air conditioners is less than 2 in step S107 (S107: No), the controller 100 proceeds to step S109. In this case, no other indoor units of air conditioners are installed in the air conditioning area of ​​the intermittently operating air conditioner, therefore the controller 100 does not perform intermittent operation suppression control.

[0121] Thus, even if there is an air conditioner operating intermittently via a compressor among multiple air conditioners (S105: Yes), and there is no indoor unit of another air conditioner system that does not operate intermittently via a compressor in the air conditioning target area where the indoor unit of that air conditioner is installed (S107: No), the controller 100 will continue the operation of the intermittently operating compressor. Therefore, it is possible to prevent the air conditioning of the predetermined air conditioning target area from being neglected in the intermittent operation suppression control.

[0122] Figure 12 This is an explanatory diagram illustrating an example of the inhibition control management table 56.

[0123] exist Figure 12 The suppression control management table 56 shown maps "Air Conditioner ID", "Operating Status", and "Suppression Control Time" together. "Air Conditioner ID" is the identification information assigned to each air conditioner. The "Operating Status" column contains information used to distinguish whether the compressor's stop status is based on intermittent operation suppression control.

[0124] In addition, under the "Operating Status" column, "Normal Operation" indicates normal air conditioning operation. "Normal Stop" indicates that the air conditioning is stopped and unrelated to intermittent operation suppression control. "Suppression Control Stopped" indicates that the air conditioning is stopped by intermittent operation suppression control. The "Suppression Control Time" column records the start time of the intermittent operation suppression control (the time when the compressor stops). Figure 12 In the example, air conditioner B1 started intermittent operation suppression control at 13:30.

[0125] Next, in Figure 9 In step S109, controller 100 determines whether the connection is registered in connection management table 51 (see reference). Figure 4 All air conditioners in the system were tested for intermittent operation (determination of whether intermittent operation occurred). If there were air conditioners that were not tested for intermittent operation (S109: No), the controller 100 process returned to step S104. Alternatively, if all air conditioners were tested for intermittent operation (S109: Yes), the controller 100 process proceeded to step S110.

[0126] In step S110, the controller 100 reads the predetermined recovery conditions from the operation recovery determination unit 20. That is, for the air conditioner subject to intermittent operation suppression control, the controller 100 selects the recovery conditions from the mode selection table 55 (see...). Figure 8 Read the predetermined recovery conditions. For example, for air conditioner B1 (refer to...) Figure 3 When intermittent operation suppression control is performed, read the data of condition N (refer to...). Figure 7 , Figure 8 () as a condition for recovery.

[0127] In step S111, controller 100 retrieves information from layout management table 52 (refer to...). Figure 5 The operating status information of the air conditioner is read out to determine whether the recovery conditions are met.

[0128] In step S112, the controller 100 determines whether the recovery condition is met. If the recovery condition is met (S112: Yes), the controller 100 proceeds to step S113. Otherwise, if the recovery condition is not met in step S112 (S112: No), the controller 100 proceeds to step S114.

[0129] In step S113, the controller 100 restarts the operation of the compressor, which was stopped in the intermittent operation suppression control. Thus, the original cooling and heating operations resume in the air conditioner containing the compressor. For example, a recovery condition K (see reference) is applied to the air conditioner that was subject to intermittent operation suppression control. Figure 7 In the event of an interrupted operation suppression control, the controller 100 performs the following processing: When the remote control is operated to enhance air conditioning in the target air conditioning zone of the air conditioner that is subject to the interrupted operation suppression control, the controller 100 stops the interrupted operation suppression control and restarts the compressor that is subject to the interrupted operation suppression control. This allows operation to be performed according to the user's intention to enhance air conditioning in a predetermined target air conditioning zone (e.g., lowering the set temperature during cooling operation). Furthermore, it prevents the load on other air conditioners that are subject to air conditioning in the target air conditioning zone from becoming excessive.

[0130] Additionally, the remote control (operated to enhance air conditioning) can also be electrically connected to the indoor unit of an air conditioner subject to intermittent operation suppression control. Alternatively, the remote control can also be electrically connected to the indoor unit of an air conditioner using a different refrigerant system than the air conditioner subject to intermittent operation suppression control. Furthermore, this indoor unit (of the other refrigerant system) is located in the air conditioning zone targeted by the air conditioner subject to intermittent operation suppression control. Moreover, when the remote control is operated to enhance air conditioning in the air conditioning zone, the compressor in the aforementioned other refrigerant system air conditioner is not driven intermittently.

[0131] Additionally, for example, regarding the condition N for recovery (refer to...) Figure 7The controller 100 can also perform the following processing: If the time average of the total power consumption of the multiple air conditioners during intermittent operation suppression control (or the power consumption when proportionally allocated to the air conditioning operating area) is greater than the time average of the total power consumption of the multiple air conditioners before the intermittent operation suppression control is executed, the controller 100 stops the intermittent operation suppression control and restarts the compressor that is the target of the intermittent operation suppression control. This improves the operating efficiency during air conditioning, thus achieving energy savings.

[0132] Next, in Figure 9 In step S114, the controller 100 determines whether there are other stopped compressors among the compressors undergoing intermittent operation suppression control that have not been processed in steps 110 to S113. If there are other stopped compressors (S114: Yes), the controller 100 returns to step S110. Alternatively, if steps 110 to S113 have been processed for all stopped compressors (S114: No), the controller 100 returns to "start" (RETURN).

[0133] Figure 13 This is a comparative example of power shift when one of the two air conditioners is operating intermittently without intermittent operation suppression control.

[0134] in addition, Figure 13 The horizontal axis represents time, and the vertical axis represents power consumption. Additionally, Figure 13 The curve shown with two solid lines represents the curve used for Figure 3 The outdoor units oB1 and oC1 of the air conditioning system in the activity area consume power according to their respective trends. Furthermore, while air conditioner C1 operates intermittently, no intermittent operation suppression control is implemented for that air conditioner C1.

[0135] in addition, Figure 13 The dashed graph illustrates the shift in power consumption of the air conditioning system proportionally allocated to the activity area. That is, the power consumption of the activity area output from the total power distribution unit 22 (in this example, the total power consumption of outdoor units oB1 and oV1 at every moment) is represented by the dashed graph. Figure 13 In the example, in the air conditioner C1 that includes outdoor unit oC1 (refer to...) Figure 3 The compressor repeatedly operates intermittently. As a result, whenever the compressor goes from stopped to running, a large amount of starting power is required, and the total power consumption of the two units (dashed line) unnecessarily increases. In other words, the power consumption used in the air conditioning of the activity area fluctuates frequently, resulting in inefficient operation.

[0136] Figure 14This refers to the data on the power shift during intermittent operation suppression control when one of the two air conditioners is operating intermittently in the air conditioning control system of this embodiment.

[0137] also, Figure 14 The horizontal / vertical axis, the division of each curve and Figure 13 The same applies, therefore its description is omitted. Figure 14 In the example, by switching air conditioner C1 to fan-only operation through intermittent operation suppression control, the operating load of another air conditioner B1 increases slightly. However, the overall power consumption of the activity area shown by the dashed line is the same as that in the comparative example (see reference). Figure 13 This represents a significant reduction compared to the previous period. Furthermore, in... Figure 14 In the example, based on predetermined recovery conditions, air conditioner C1 resumes air conditioning operation from suppression control operation in about 1.5 hours.

[0138] <Effect>

[0139] According to this embodiment, the controller 100 determines in real time which air conditioners are operating intermittently (inefficiently), and stops the compressors of other air conditioners operating intermittently when other indoor units are present in the air conditioning area. This reduces the overall power consumption of multiple air conditioners. Furthermore, in air conditioning areas that are operating in cooling or heating mode, it prevents air conditioning from being impossible due to the intermittent operation suppression control. Thus, in this embodiment, an air conditioning control system X1 is provided that appropriately regulates the air in the air conditioning area and achieves energy savings.

[0140] Variations

[0141] The air conditioning control system X1 and air conditioning control method of this disclosure have been described above through embodiments, but are not limited to these descriptions and various modifications can be made.

[0142] For example, in one embodiment, it is described that when an air conditioner that operates intermittently via a compressor is in cooling operation, the controller 100 stops the compressor and switches to fan operation, but it is not limited to this. That is, in intermittent operation suppression control, the controller 100 may also stop the compressor, causing the air conditioner to change from cooling operation to a stopped state.

[0143] Furthermore, in the embodiment, it was described that when the air conditioner, which operates intermittently via a compressor, is in heating mode, the controller 100 stops the compressor, thus stopping the operation of the indoor unit of the air conditioner. However, this is not the only possibility. That is, in intermittent operation suppression control, the controller 100 may also stop the compressor and switch the indoor unit from heating mode to fan operation. In short, when the controller 100 performs intermittent operation suppression control, it may also stop the operation of the indoor unit of the air conditioner, which includes the intermittently operating compressor, or switch the operation mode of the indoor unit of the air conditioner to fan operation.

[0144] In addition, the program executed by the controller 100 (the program of the air conditioning control method) can be provided not only through the communication line, but also written to a recording medium such as a CD-ROM for distribution.

[0145] Furthermore, the embodiments described in detail are for the purpose of easily understanding and illustrating this disclosure, and are not necessarily limited to having all the structures described. In addition, with respect to a part of the structure of the embodiments, other structures can be added, deleted, or replaced.

[0146] In addition, the aforementioned mechanisms and structures represent those that are deemed necessary for the description, but may not represent all mechanisms and structures on the product.
