Description

[Technical Field]

[0001] The technology disclosed herein relates to an air conditioning control device and an air conditioning system, and in particular to support for setting an operation schedule for air conditioning equipment. [Background technology]

[0002] Air conditioning control devices that control air conditioning in a space to be air-conditioned using air conditioners and the like have been available for some time. A typical air conditioning control device can schedule in advance the operation of an air conditioning system that has air conditioning devices that perform air conditioning, such as air conditioners and ventilators. The air conditioning control device can then switch the air conditioners and the like to perform specified operations at specified times based on an operation schedule set in advance by an administrator. This reduces the number of device operations by the administrator throughout the day, and allows the space to be kept in the desired air-conditioned state even when the administrator is absent.

[0003] Furthermore, it is difficult to achieve an efficient operation method for multiple air conditioners, or to achieve both comfort and air conditioning efficiency by promoting ventilation, using only the information available at the time of schedule setting. For this reason, a system has been proposed that automatically creates an operation schedule that aims to improve comfort and energy conservation based on information available after setting, such as operating history, information on the air quality of the space, and predicted changes in the external environment (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-035242 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, conventional air conditioning control devices can automatically set the control details for air conditioning equipment in an entire air conditioning system, enabling operation according to a better operating schedule. However, when considering the operation of an actual air conditioning system, there are people in a variety of positions. Therefore, depending on how the control details are evaluated, it is conceivable that there will be both people who perceive the execution of automatic control as an advantage and people who perceive it as a disadvantage. Furthermore, there is a possibility that changes to the control details will result in complaints from people who perceive it as a disadvantage.

[0006] For example, people in an air-conditioned space tend to prioritize the comfort of the space brought about by air conditioning. On the other hand, people in a managerial position outside the air-conditioned space tend to prioritize energy conservation. For this reason, if a manager changes the control content to an operation schedule that prioritizes energy conservation, the people in the air-conditioned space may feel uncomfortable, and a conflict of interest may arise. In this case, it is desirable for the manager to be able to rationally explain whether the schedule change was appropriate and whether the setting change was within a range that would not cause discomfort.

[0007] Therefore, an object of this disclosure is to provide an air conditioning control device and an air conditioning system that can provide support for setting an operation schedule, etc., when displaying the operation schedule, etc. [Means for solving the problem]

[0008] In order to solve the above problems, the air conditioning control device disclosed herein is an air conditioning control device that manages operation schedules related to the control content of air conditioning equipment that conditions the air in the space to be air-conditioned, and is equipped with an operation history memory unit that stores data on the operation history of the air conditioning equipment in the space to be air-conditioned, and a display processing unit that searches the operation history memory unit for past operation history to be displayed together with the operation schedule set for the air conditioning equipment, and creates a screen signal that displays the operation schedule together with the searched operation history on a display device.

[0009] In addition, the air conditioning system according to this disclosure comprises an air conditioning device to be controlled, the air conditioning control device described above, and a display device that displays information based on a screen signal created by the air conditioning control device. [Effects of the Invention]

[0010] According to this disclosure, it is possible to perform display processing that visually shows a comparison between the control details based on the operation schedule and the operation record. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of an air conditioning control device (hereinafter referred to as an air conditioning control device) will be described with reference to the drawings. Hereinafter, in the drawings, parts with the same reference numerals are the same or equivalent, and are common throughout the embodiments described below. Furthermore, the forms of components shown throughout the specification are merely examples and are not limited to these descriptions. In particular, the combinations of components are not limited to the combinations in each embodiment, and components described in other embodiments can be applied to other embodiments as appropriate.

[0013] Embodiment 1 FIG. 1 is a diagram showing the configuration of an air conditioning system centered around an air conditioning control device 100 according to embodiment 1. The air conditioning system according to embodiment 1 includes an air conditioning device 10, a ventilator 20, the air conditioning control device 100, and a display device 200 such as a display. The air conditioning device 10 and the ventilator 20 are air conditioning devices that condition the air in the space to be air-conditioned. Here, a case will be described in which the air conditioning devices that are the targets of management by the air conditioning control device 100 are one each of the air conditioning device 10 and the ventilator 20. However, the types and number of air conditioning devices that are managed by the air conditioning control device 100 are not limited to this.

[0014] The air conditioning control device 100 manages control details related to the operation of the air conditioner 10 and the ventilator 20 as an operation schedule. In particular, the air conditioning control device 100 in the first embodiment displays on the display device 200 an operation schedule obtained by an administrator through settings or the like, along with operating records related to past operation, thereby providing management support to the administrator. Here, the explanation is given assuming that the administrator issues instructions to the air conditioning control device 100. Furthermore, the operating records are, for example, physical quantities that represent the environment of the air-conditioned space obtained by operating the air conditioning equipment. Here, in the first embodiment, the explanation is given assuming that the operating records are the indoor temperature and carbon dioxide concentration of the air-conditioned space, as an example. The indoor temperature and carbon dioxide concentration are detected by a temperature sensor and a carbon dioxide sensor, respectively, installed in the air-conditioned space. The air conditioning control device 100 in the first embodiment has a management processing unit 110, a memory unit 120, a communication unit 130, an input unit 140, an output unit 150, and a timing unit 160.

[0015] The management processing unit 110 controls the operation of each unit in the air conditioning control device 100, for example, by processing data included in signals from the communication unit 130 and the input unit 140. In particular, in the first embodiment, the management processing unit 110 combines the operation schedule, which is set and displayed on the screen of the display device 200, with the operating results of past operations corresponding to the operation schedule, and creates a screen signal for displaying them together. Therefore, the management processing unit 110 in the first embodiment has a result processing unit 111, a setting processing unit 112, and a display processing unit 113.

[0016] The performance processing unit 111 processes data included in the operation signal from the communication unit 130. The operation signal includes, for example, performance data indicating the performance of the operation as described above, and operation information data indicating operation instructions given by a user operating the air conditioning device in the air-conditioned space using a remote controller for the air conditioning device or a smartphone or tablet (not shown) with a dedicated application installed. For example, an operation such as changing the temperature is performed on the air conditioning device 10. Furthermore, an operation such as changing the airflow volume is performed on the ventilation device 20. The performance processing unit 111 associates this data with time data related to the timing of the timing unit 160 and records the data in the storage unit 120. Furthermore, the setting processing unit 112 sets and changes the operation schedule of the air conditioning device in the air-conditioned space based on an input signal from the input unit 140. The setting processing unit 112 then creates schedule data based on the operation schedule and stores the schedule data in the storage unit 120. Based on instructions from the administrator, the display processing unit 113 searches the storage unit 120 for the operation schedule related to the setting and past operation performance data to be displayed together with the operation schedule. Then, the display processing unit 113 generates a screen signal for displaying the operation schedule and the operation record together on the display device 200.

[0017] The storage unit 120 temporarily or long-term stores, records, and saves (hereinafter simply referred to as "storage") various data used by each unit of the management processing unit 110 when performing processing. In particular, the storage unit 120 in the first embodiment has an operation record storage unit 121, an operation schedule storage unit 122, and an operation information storage unit 123. The operation record storage unit 121 stores the operation record data created by the record processing unit 111 described above. Furthermore, the operation schedule storage unit 122 stores the schedule data created by the setting processing unit 112 described above. Here, it is assumed that the operation schedule storage unit 122 stores schedule data of an operation schedule that is currently being executed or is to be executed in an air conditioning system, for example. Furthermore, the operation information storage unit 123 stores the operation information data created by the record processing unit 111.

[0018] The communication unit 130 is connected to enable communication between the air conditioning device 10 and the ventilator 20. The communication unit 130 serves as an interface for signal communication between the air conditioning device 10, the ventilator 20, and the management processing unit 110. The communication unit 130 converts transmitted signals, for example, so that the management processing unit 110 can process data.

[0019] The input unit 140 sends an input signal including data such as instructions or settings input by an administrator via an input device such as a keyboard or a touch panel to the management processing unit 110. In the first embodiment, for example, instructions regarding screen operations displayed on the display device 200, data regarding operation schedule settings, etc. are input by the administrator. Here, the input unit 140 may send a signal including data from an external device as an input signal to the management processing unit 110. The timing unit 160 measures time and sends a time signal including time data to the management processing unit 110. The output unit 150 converts a screen signal based on the processing of the management processing unit 110 into a display signal to be displayed on the display device 200 and sends the display device 200.

[0020] Here, the management processing unit 110 is assumed to be configured, for example, by a microcomputer having a control arithmetic processing unit such as a CPU (Central Processing Unit). The storage unit 120 has, for example, a volatile storage device (not shown) such as a random access memory (RAM) that can temporarily store data, and a non-volatile auxiliary storage device (not shown) such as a flash memory that can store data for the long term. The storage unit 120 stores program data that describes the processing procedures to be performed by the management processing unit 110. The control arithmetic processing unit executes the processing based on the program data. However, this is not a limitation. The device that performs the processing may also be configured as dedicated equipment (hardware), for example.

[0021] FIG. 2 is a diagram showing an example of a screen displayed on the display device 200 by processing of the air conditioning control device 100 according to Embodiment 1. In FIG. 2, the air conditioning control device 100 according to Embodiment 1 displays a one-day operation schedule for the air conditioning device 10 and the ventilator 20 in chronological order. At this time, the operation performance for one day is also displayed as a chronological graph. In FIG. 2, as the operation performance, the indoor temperature is displayed as a line graph, and the carbon dioxide concentration is displayed as a bar graph. For the indoor temperature, the period from when the air conditioning device 10 starts operating to when it stops operating is shown by a solid line, and other periods are shown by dotted lines.

[0022] FIG. 3 is a diagram illustrating the processing flow of the display processing unit 113 according to the first embodiment. When the manager issues an instruction to display an operation schedule via the input unit 140 (step S1), the display processing unit 113 searches the operation schedule storage unit 122 of the storage unit 120 for operation schedule data based on the instruction (step S2). Basically, the operation schedule currently set for controlling the air conditioning appliances becomes the operation schedule to be displayed. Furthermore, based on the operation schedule to be displayed, the display processing unit 113 searches the operation record storage unit 121 of the storage unit 120 for past operation record data that satisfies a condition with the operation schedule to be displayed (step S3). For example, the condition may be to search for operation records performed under the same operation schedule. Then, based on the searched schedule data and operation record data, the display processing unit 113 creates a screen signal for displaying on a screen a combination of the set operation schedule and the operation record that satisfies the condition (step S4).

[0023] For example, when an operation schedule is set for each day of the week, the display processing unit 113 searches the operation schedule storage unit 122 for actual driving performance data for the same day of the week as the day of the week set in the operation schedule to be displayed during a specific past period.The display processing unit 113 then combines the driving performance data for the same day of the week with the operation schedule to create a screen signal.Here, when multiple pieces of actual driving performance data for the same day of the week are stored in the operation schedule storage unit 122, the display processing unit 113 creates a screen signal based on the most recently stored driving performance data in terms of date and time, for example.

[0024] As described above, according to the air conditioning control device 100 of the first embodiment, the display processing unit 113 of the management processing unit 110 can perform display processing that causes the display device 200 to display the operation schedule to be displayed together with the corresponding operating results of past operations that satisfy the conditions. This allows, for example, a manager or the like to easily compare the set operation schedule with the operating results, and more visually appeals to the effectiveness of the set operation schedule. This allows the manager to rationally explain the validity of the set operation schedule.

[0025] Embodiment 2 Fig. 4 is a diagram showing an example of a screen displayed on the display device 200 by processing of the air conditioning control device 100 according to embodiment 2. As shown in Fig. 4, the display processing unit 113 searches the storage unit 120 and determines whether operation information data corresponding to the operation record displayed together with the operation schedule is stored in the operation information storage unit 123. When the operation information data is stored in the operation information storage unit 123, the display processing unit 113 creates a screen signal for displaying the operation information in an overlaid manner, and displays it on the display device 200. For example, the display screen shown in Fig. 4 shows an example in which the set temperature in the operation schedule, which was set to 26°C and was in cooling operation, has been changed to 24°C by operation.

[0026] As described above, according to the air conditioning control device 100 of the second embodiment, the display processing unit 113 displays operation information superimposed on the operation schedule and operation record based on the operation information data stored in the operation information storage unit 123. This makes it possible to display the operation record when the air conditioning equipment is operated. This allows the administrator to provide a rational explanation, such as showing the validity of the operation schedule.

[0027] Embodiment 3 The air conditioning control device 100 in the first embodiment described above combines a one-day operation schedule for the air conditioner 10 and the ventilator 20 with operation results that satisfy the conditions in the operation schedule and displays this on the display device 200. The air conditioning control device 100 in the third embodiment further combines predicted effects of changes to the operation schedule and displays this on the display device 200.

[0028] Fig. 5 is a diagram showing the configuration of an air conditioning system according to embodiment 3. In Fig. 5, parts and the like denoted by the same reference numerals as in Fig. 1 basically perform the same processing operations as those explained in embodiment 1. Here, the setting processing unit 112 in embodiment 3 performs processing related to changes to the operation schedule by the administrator, for example.

[0029] The management processing unit 110 has an effect estimation unit 114. The effect estimation unit 114 predicts and estimates changes in operation performance based on the control content of the operation schedule changed by the setting processing unit 112. Then, the display processing unit 113 creates a screen signal that displays the change in operation performance predicted and estimated by the effect estimation unit 114 superimposed on the operation performance. At this time, the display processing unit 113 causes the display device 200 to display the changed portion of the control content during a period suitable for display. The suitable period is, for example, the period from the start time of control based on the changed control content to the start time of the next control based on the unchanged control content.

[0030] Here, we will explain the prediction of carbon dioxide concentration as an example. To predict the carbon dioxide concentration in the air-conditioned space, a carbon dioxide concentration prediction model is used, which inputs, for example, the ventilation rate, the carbon dioxide concentration outside the air-conditioned space, and the amount of carbon dioxide generated by human bodies, and outputs the carbon dioxide concentration in the air-conditioned space. The ventilation rate is determined by the control details regarding the airflow rate of the ventilation device 20 in the operation schedule and the volume of the air-conditioned space. For example, the carbon dioxide concentration outside the air-conditioned space is a standard setting value. The amount of carbon dioxide generated by human bodies is a value obtained, for example, by settings by an administrator or learning about entry and exit to the air-conditioned space. For indoor temperature prediction, the time change in the heat processing capacity of the air conditioner 10 required to maintain the air-conditioned space at a set temperature is predicted. For this, a thermal prediction model, such as a building's thermal characteristics, is used, which is based on a heat transport equation, which is a relational expression for time changes in outdoor temperature, solar radiation, etc.

[0031] FIG. 6 is a diagram showing an example of a screen displayed on the display device 200 by processing of the air conditioning control device 100 according to embodiment 3. In FIG. 6, the section showing change effect example 1 shows a change made to the ventilation device 20 to advance the start time for switching to ventilation (strong). Furthermore, the section showing change effect example 2 shows a change made to the ventilation device 20 to add ventilation (strong), remove ventilation (medium), and advance the start time for 24-hour ventilation. In both cases of change effect example 1 and change effect example 2, the results predicted and estimated by the effect estimation unit 114 show that the carbon dioxide concentration is suppressed. Based on this display, the administrator determines whether to reflect the change to the operation schedule of the air conditioning equipment, and makes the change again or reflects the change in the operation schedule.

[0032] As described above, according to the air conditioning control device 100 of the third embodiment, the display processing unit 113 creates a screen signal that displays the change in the operating performance predicted and estimated by the effect estimation unit 114 on the display device 200 by superimposing it on the operating performance. By showing the effect of changing the control content of the operating schedule, it is possible to show the appropriateness of the change in the operating schedule, etc.

[0033] Embodiment 4 In the air conditioning control device 100 according to Embodiment 1, the display processing unit 113 extracts operating history data for the same day of the week and creates a screen signal. For example, if the same operating schedule is set for multiple days of the week, the display processing unit 113 may search for operating history data from among the multiple days of the week and create a screen signal.

[0034] Furthermore, in the first embodiment, if there was more than one piece of operating history data that met the same conditions, such as the same day of the week, the display processing unit 113 created a screen signal based on the most recently stored operating history data. In this regard, the air conditioning control device 100 may be configured to allow the user to select from more than one operating history data, and to switch to displaying the operating history data based on the selection.

[0035] For example, multiple operating records that meet a condition, such as the same day of the week, may not necessarily be the same due to disturbances such as the number of people in the air-conditioned space, the outdoor temperature outside the air-conditioned space, and the weather on that day. Therefore, the display processing unit 113 may create a screen signal to be displayed on the display device 200 by calculating at least one of the average, median, maximum, and minimum values ​​from the multiple operating record data that meet the conditions. Furthermore, for example, buttons for selecting "many people," "few people," "high outdoor temperature," and "low outdoor temperature" may be displayed on the display device 200 so that an administrator or the like can make a selection. The display processing unit 113 may then create a screen signal for switching the display to the operating record corresponding to the selected button from the multiple operating records, or for overlaying the selected button, and display the screen signal on the display device 200.

[0036] Furthermore, the air conditioning control device 100 may perform display based on a screen signal created by the display processing unit 113 in combination with the display content described in Embodiments 1 to 3. For example, the display processing unit 113 calculates the average or median value of operating performance data from multiple operating performance data that fall under conditions such as the same day of the week, and creates a screen signal to display on the screen together with a set operating schedule. Then, when an administrator or other person issues an instruction to display operating performance based on the number of people in the air-conditioned space, disturbances such as the outside temperature, user operations, etc., the display processing unit 113 creates a screen signal to change the display to the operating performance selected and instructed by the administrator from among the multiple operating performance data.

[0037] For example, when the manager changes the operation schedule based on the operation record displayed on the display device 200, the effect estimation unit 114 predicts and estimates changes in the operation record. The display processing unit 113 creates a screen signal that further combines the predicted and estimated operation record. The output unit 150 converts the screen signal into a display signal and displays it on the display device 200. Based on this display, the manager determines whether to reflect the change in the operation schedule of the air conditioning equipment, and makes the change again or reflects the change in the operation schedule. In this way, the air conditioning control device 100 can support the setting of a more optimal operation schedule.

[0038] In the above-described third embodiment, the effect estimation unit 114 predicts and estimates changes in the operating performance based on changes in the control content in the operation schedule. Here, the effect estimation unit 114 may be configured to have AI (Artificial Intelligence). The effect estimation unit 114 processes the changed control content as input data using a prediction model of operating performance such as carbon dioxide concentration and indoor temperature, and predicts and estimates changes in the operating performance.

[0039] In the above-described first embodiment, the operation schedule is set by an administrator, but this is not limiting. The operation schedule may be set by an external device or automatically set.

[0040] In addition, in the above-described first embodiment and the like, the indoor temperature and carbon dioxide concentration are described as being displayed as the operating performance, but this is not limited to this. For example, the power consumption of the air conditioner may also be displayed as the operating performance.
