Air conditioning systems are equipped with a variety of air conditioning equipment, including various heat source units such as chillers, pumps, fans, and heat exchangers. The performance of each piece of air conditioning equipment changes depending on the operating conditions and maintenance status as well as deterioration over time. Therefore, the air conditioning system manager checks the performance of each piece of air conditioning equipment and, if necessary, may review the equipment operation, such as the operating method and maintenance content.

Operating methods and maintenance details generally vary slightly from property to property, and they are rarely shared between properties. In reality, performance checks of air conditioning equipment are carried out based on, for example, comparisons with catalog values or initial operating values listed in materials provided by the equipment manufacturer, comparisons with other units with similar usage conditions, or intuitive judgments based on years of experience. However, because whether or not air conditioning equipment performs as it should is largely dependent on the appropriateness of equipment operation, it is often more useful to compare performance with equipment in other properties where different equipment operation may be used.

Therefore, this application discloses an information processing device, method, and program that enables consideration of facility operation while obtaining a comprehensive overview of the air conditioning equipment installed in each property.

To solve the above problem, the present invention displays the performance evaluation points of an air conditioner selected on a screen that lists the air conditioners for each property on a graph with time-dependent factors as the axis, regardless of the property in which the air conditioner is installed.

In detail, the present invention is an information processing device capable of communicating with an air conditioning system management device installed in each property, and includes an equipment selection reception processing unit that receives an air conditioning equipment selection operation performed on a screen that displays a list of the air conditioning equipment in each property, and a graph display processing unit that displays the performance evaluation points of each air conditioning equipment selected by the selection operation on a graph with time-dependent factors as the axis.

Here, the term "object" refers to an object in which an air conditioning system is installed, and includes, for example, buildings, factories, plants, research facilities, underground shopping malls, houses, train stations, railroad cars, buses, aircraft, spacecraft, and any other object that can be air-conditioned. The temporal element is a value that quantitatively indicates the degree of progress over time, such as the number of years that the equipment has been in operation, the operating hours of the equipment, and the number of times the equipment has been started and stopped. The performance evaluation point is a value that quantitatively indicates the performance of the air conditioning equipment, such as a value that indicates the ratio of the actual capacity to the design rated capacity expressed as a percentage.

With such an information processing device, the performance evaluation points of all selected air conditioners are displayed on a graph with time-dependent factors as the axis. This allows the user to easily compare whether the performance evaluation point of a specific air conditioner is inferior to the performance evaluation points of air conditioners in other properties, and allows the user to consider facility operation while getting a comprehensive overview of the air conditioners installed in each property.

The graph display processing unit may further draw a line or curve showing the regression of the performance evaluation points of each selected air conditioner. If the regression line or regression curve of the performance evaluation points is displayed on a graph, the relative merits and demerits of each air conditioner can be easily grasped.

The graph display processing unit may also display on a graph the performance evaluation points of each air conditioner selected by a selection operation from among the performance evaluation points of the air conditioners of each property that are periodically calculated and stored in the storage device. Because the performance of air conditioners does not change suddenly, it is practically acceptable for values calculated by periodic calculations to be displayed on a graph. Furthermore, if values calculated by periodic calculations are displayed on a graph, the user will not have to wait for the calculation process to be completed each time they request a graph.

The present invention can also be viewed as a method. For example, the present invention may be an information processing method executed by an information processing device capable of communicating with an air conditioning system management device installed in each property, which performs an equipment selection reception process that receives an air conditioning equipment selection operation performed on a screen that lists the air conditioning equipment of each property, and a graph display process that displays the performance evaluation points of each air conditioning equipment selected by the selection operation on a graph with time-dependent factors as the axis.

The present invention can also be viewed from the perspective of a program. For example, the present invention may be an information processing program executed by an information processing device capable of communicating with an air conditioning system management device installed in each property, which causes the information processing device to execute an equipment selection reception process that receives an air conditioning equipment selection operation performed on a screen that lists the air conditioning equipment of each property, and a graph display process that displays the performance evaluation points of each air conditioning equipment selected by the selection operation on a graph with time-dependent factors as the axis.

The above information processing device, method, and program make it possible to consider equipment operation while getting an overview of all the air conditioning equipment installed in each property.

The following describes an embodiment of the present invention. The embodiment described below is an example of an embodiment of the present invention, and does not limit the technical scope of the present invention to the following aspects.

1 is a diagram illustrating an image of the entire information processing system for an air conditioning system. As shown in FIG. 1, the information processing system 1 of this embodiment includes a BEMS (Building Energy Management System) server (hereinafter simply referred to as "server") 3 connected by a communication network to the management devices of the air conditioning systems installed in each property 2A, 2B, and 2C, and a client computer (hereinafter referred to as "terminal") 4 that can access the server 3. The server 3 and the terminal 4 include a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), a communication interface, etc., and realize various functional units by executing a computer program. The terminal 4 realizes various functional units such as an equipment selection reception processing unit 4A and a graph display processing unit 4B, for example, by executing a computer program for the air conditioning system that monitors the status of the air conditioning system of each property.

Figure 2 is a diagram illustrating the flow of information processing performed in information processing system 1. The storage device of server 3 stores a database containing information such as the names and models of air conditioning equipment installed in each property 2A, 2B, 2C and calculation formulas, as well as a database containing definition information for graphs to be displayed on terminal 4 and definition information for screen transitions. These databases are generated by the administrator of server 3, for example, by performing creation work according to the procedure shown in the "setting flow" in Figure 2.

For example, the variable master database shown in FIG. 2 is a database that stores variables and their attributes, and sets data types for determining the variable name, the variable code that the BEMS system distinguishes, the unit, the target device/system name, the measurement attribute, or the evaluation index, etc. In addition, in the case where the variable required for evaluation is not included in the measurement data and calculation is possible from other measurement variables, the target calculation formula is directly input in the target variable (hereinafter, referred to as the calculation variable) setting. The graph master database is a database that stores graph settings to be displayed in the GUI, and sets the graph type such as trend graph or plot graph, the variables to be displayed, the reference line, etc. The graph configuration master database is a database that stores the function for displaying the target graph and the screen configuration settings within the function, and is a database that allows the BEMS user to quickly transition to related graphs in order to understand the energy usage status, the causes of energy saving or waste, and the maintenance status of the equipment.

In addition, the storage device of the server 3 stores a database containing measured values, a database containing calculated values obtained through various calculations, and the like. The measured values are obtained by the server 3 accessing the management device of the air conditioning system installed in each of the properties 2A, 2B, and 2C, for example, at regular intervals. The calculated values are generated by periodic calculation processing performed on the server 3 or the cloud based on the calculation formula and information on the measured values stored in the database. For example, the performance evaluation points described below, which quantitatively represent the performance of the air conditioning equipment, are not values that change suddenly. Therefore, for example, it is practically acceptable to use values calculated in advance by periodic calculation processing about once a day for graph display. And if such calculated values are calculated in advance by periodic calculation, the user of the terminal 4 does not have to wait for the completion of the calculation processing every time he requests graph display, for example. The calculated values generated in this way are used by the user of the terminal 4, for example, by operating the terminal 4 to call up the graph, as shown in the "operation flow" of FIG. 2.

For example, the measurement variable database shown in Figure 2 is a database that stores measurement data uploaded at regular sampling times, and after storing all measurement data, it outputs the measurement variables required for calculation based on the definition of the calculation variables set in the variable master database as explanatory variables. In addition, the calculation variable database is a database that stores measurement variables and calculation variables, and when a BEMS user requests graph viewing and data acquisition via the GUI (for example, output as csv text data), it outputs the data of the date, time, and period when the required variables in this database were requested.

Figure 3 is a diagram illustrating an example of how the calculated values are used. In the information processing system 1 of this embodiment, the server 3 centrally collects information on air conditioning equipment installed in various properties, and the database of the server 3 stores data such as calculated values related to the air conditioning equipment of various properties. Therefore, a user of the terminal 4 can select multiple air conditioning equipment across three properties 2A, 2B, and 2C for which the performance is to be compared, as shown in Figure 3, and display the results in a graph on the terminal 4.

Fig. 4 is a diagram showing an example of a portal screen of the BEMS. When the server 3 is accessed from the terminal 4, for example, a portal screen of the BEMS as shown in Fig. 4 is displayed on the terminal 4. In the information processing system 1, information on the air conditioning equipment of various properties is managed in a centralized manner. Therefore, for example, as shown in Fig. 4, the portal screen displayed on the terminal 4 displays a property selection button B1, an ^m2 consumption correlation button B2 for calling a screen showing the correlation between the floor area of the property and the energy consumption, a ranking rough button B3 for calling a screen showing the ranking of the energy consumption among the properties, an equipment performance evaluation button B4 for calling a screen showing the evaluation results of the performance of the air conditioning equipment (hereinafter referred to as "equipment performance evaluation screen"), and the like.

The BEMS portal screen may be displayed, for example, by the server 3 receiving an HTTP (Hypertext Transfer Protocol) request from the terminal 4 for calling up the BEMS portal screen, generating the screen in HTML (Hypertext Markup Language) format based on information stored in its own database, and processing the data in the browser of the terminal 4, or by a dedicated application installed in the terminal 4 superimposing data from the server 3 on graphic data of the equipment performance evaluation screen. Each screen described below is also displayed by similar processing.

When, for example, a property selection button B1 is pressed on the BEMS portal screen, the portal screen of the selected property is displayed. FIG. 5 is a diagram showing an example of a property portal screen. When a property selection button B1 is pressed on the BEMS portal screen, for example, a property portal screen as shown in FIG. 5 is displayed on the terminal 4. In the information processing system 1, data such as the power consumption and outdoor temperature of the air conditioning system in each property is recorded, and the operation status is automatically diagnosed based on the recorded data. Therefore, for example, as shown in FIG. 5, a power consumption trend graph and diagnosis results are displayed on the property portal screen displayed on the terminal 4. In addition, for example, a today's details button B5 for calling up a detailed screen of the energy consumption status of the day, a past details button B6 for calling up a detailed screen of the energy consumption status of the past, a data export button B7 for calling up a screen for outputting various data such as power consumption in file format, a user graph button B8 for calling up a screen showing data of items set by the user of the terminal 4 in a trend graph, and a menu button B9 for calling up a menu screen with various other buttons arranged are displayed on the property portal screen. By displaying such a screen, the user of terminal 4 can easily understand the energy consumption situation in a specific property.

Figure 6 is an example of a screen showing details of the energy consumption situation. When the Today Details button B5 is pressed on the portal screen of the property shown in Figure 5, for example, a trend graph of the electricity consumption amount for the selected property for that day and the diagnosis results are displayed in detail, as shown in Figure 6. When the Past Details button B6 is pressed on the portal screen of the property shown in Figure 5, a similar screen is displayed, except that the data displayed is replaced with past data. By displaying such a screen, the user of terminal 4 can grasp the energy consumption situation for a specific property in detail.

Figure 7 is an example of an operation screen for exporting data. When the data export button B7 is pressed on the property portal screen shown in Figure 5, an operation screen is displayed for specifying the range of data to be exported, such as the start date and end date, as shown in Figure 7, for example. When an appropriate range is set here and the execute button B10 is pressed, a file listing the data for the set range is generated on terminal 4. By generating a file through such a screen, the user of terminal 4 can use the data in the generated file for various analyses, etc.

Figure 8 is an example of a screen that shows data for items set by the user in a graph. When the user graph button B8 is pressed on the property portal screen shown in Figure 5, a trend graph showing data related to the items set by the user is displayed, for example, as shown in Figure 8. By displaying such a screen, the user of terminal 4 can easily grasp the trends in data related to the items that he or she is interested in.

Fig. 9 is an example of a menu screen. When the menu button B9 is pressed on the portal screen of the property shown in Fig. 5, buttons for calling various screens are displayed, for example, as shown in Fig. 9. On the menu screen, for example, as shown in Fig. 9, various buttons are displayed, such as an energy flow button B11 for calling a screen showing the energy balance of the property, a hierarchical graph button B12 for calling a screen handling a hierarchical graph of various data items, a category graph button B13 for calling a screen displaying a graph of various data items by category, a correlation causal analysis button B14 for calling a screen showing the correlation between each air conditioning device, a system diagram display button B15 for calling a screen showing the operating status of the air conditioning device in a system diagram, and an equipment diagnosis result list button B16 for calling a screen showing a list of the diagnosis results of each air conditioning device.

Figure 10 is an example of a screen showing energy flow. When the energy flow button B11 is pressed on the menu screen shown in Figure 9, for example, as shown in Figure 10, a diagram is displayed that intuitively shows the amount of energy input and output to the property. By displaying such a screen, the user of terminal 4 can easily understand the energy balance of the property.

Figure 11 is an example of a hierarchical graph screen. When the hierarchical graph button B12 is pressed on the menu screen shown in Figure 9, for example, as shown in Figure 11, a screen is displayed having a graph column R1 and a data item selection column R2 for selecting the data items to be displayed in the graph. By displaying such a screen, the user of terminal 4 can grasp the status of the air conditioning equipment by comparing various graphs that he or she has selected and displayed side by side in graph column R1.

Figure 12 is an example of a screen showing graphs by category. When the graph by category button B13 is pressed on the menu screen shown in Figure 9, a screen showing a graph of various data items by category is displayed, for example, as shown in Figure 12. By displaying such a screen, the user of terminal 4 can understand the status of the air conditioning equipment by looking at a graph of any data item selected from those organized by category.

Figure 13 is an example of a screen showing the correlation between each air conditioning device. When the correlation causal analysis button B14 is pressed on the menu screen shown in Figure 9, for example, as shown in Figure 13, the names of other data items that are related to a specific data item are displayed on a radar chart, and a screen showing the strength of the correlation causal relationship between the data items is displayed. By displaying such a screen, the user of terminal 4 can easily grasp the names of other data items that are related to any data item that he or she has selected as his or her focus.

Figure 14 is an example of a screen showing the operating status of the equipment in a system diagram. When the system diagram display button B15 is pressed on the menu screen shown in Figure 9, for example, as shown in Figure 14, a screen is displayed showing a schematic system diagram of the entire air conditioning system installed in the property together with marks indicating the operating status. By displaying such a screen, the user of terminal 4 can easily understand the operating status of the air conditioning system installed in the property.

Figure 15 is an example of a screen showing the diagnosis results of each air conditioning device. Also, Figure 16 is an example of a screen showing detailed diagnosis results of air conditioning devices. When the device diagnosis result list button B16 is pressed on the menu screen shown in Figure 9, the results of the automatic diagnosis of the air conditioning devices installed in the property are displayed in a list, for example, as shown in Figure 15. When the details button B17 on the diagnosis result screen shown in Figure 15 is pressed, a screen showing detailed diagnosis results of the air conditioning devices, for example, as shown in Figure 16, is displayed. By displaying such a screen, the user of terminal 4 can understand the results of the automatic diagnosis of each air conditioning device installed in the property.

Fig. 17 is an example of a screen showing the correlation between the floor area and energy consumption of a property. When the ^m2 consumption correlation button B2 is pressed on the BEMS portal screen shown in Fig. 4, for example, a screen is displayed in which data for each property is plotted on a graph with the floor area of the property on the horizontal axis and the energy consumption of the air conditioning system on the vertical axis, as shown in Fig. 17. By displaying such a screen, the user of the terminal 4 can easily see the correlation between the floor area and energy consumption of the property and compare properties.

Figure 18 is an example of a screen showing a ranking of energy consumption between properties. When the ranking button B3 is pressed on the BEMS portal screen shown in Figure 4, a screen is displayed that shows a ranking of the energy consumption of air conditioning systems and the energy consumption per unit floor area between properties, as shown in Figure 18, for example. By displaying such a screen, the user of terminal 4 can easily compare the energy consumption of air conditioning systems between properties.

Figure 19 is a diagram showing a first example of an equipment performance evaluation screen. When the equipment performance evaluation button B4 is pressed on the BEMS portal screen shown in Figure 4, the performance evaluation results of the air conditioning equipment are displayed in a list in the form of a table, as shown in the center of Figure 19, for example. The list of air conditioning equipment includes various information such as the name of the property in which it is installed, the type of equipment, years of operation, operating time, number of starts and stops, and performance evaluation points. The years of operation, operating time, and number of starts and stops of the equipment can be obtained, for example, based on the start/stop flag of the equipment for each sampling time of the data recorded in the measurement variable database.

The performance evaluation score can be obtained based on the data recorded in the measurement variable database or the values specified in the variable master database. The performance evaluation score of the chiller may be, for example, a value expressed as a percentage of the catalog value (or the performance value at the beginning of operation) based on the coefficient of performance (a value obtained by dividing the amount of heat produced by the input energy, also called COP (Coefficient of Performance)) calculated from the average amount of heat produced, the cold water outlet temperature (production temperature), and the cooling water inlet temperature (cooling water supply temperature) on the target day during operation, or a value expressed as a percentage of the catalog value (or the performance value at the beginning of operation) based on the COP calculated from the cold water outlet temperature (production temperature) and the cooling water inlet temperature (cooling water supply temperature) at the time when the maximum amount of heat produced is output on the target day. Furthermore, the performance evaluation score for pumps and fans is, for example, the power or current value at the time when the maximum flow rate (or air volume) is output on the target day, expressed as a percentage based on the catalog value (or performance value at the beginning of operation).

The left side of the equipment performance evaluation screen in FIG. 19 provides an equipment selection field R3 for selecting the equipment to be displayed in a list. The equipment selection field R3 displays the names of the equipment in a tree diagram. Above the equipment selection field R3, there are provided a property button B18, which is a button for displaying the air conditioning equipment displayed in the equipment selection field R3 by property, and an equipment type button B19, which is a button for displaying by equipment type. Also, below the equipment performance evaluation screen in FIG. 19, there is provided a graph button B20, which displays the performance evaluation points of the air conditioning equipment displayed in the list in a graph with time-dependent factors on the horizontal axis.

The air conditioning equipment to be displayed in a list on the equipment performance evaluation screen is selected, for example, as follows. FIG. 20 is a diagram showing a first example of the equipment selection field R3 on the left side of the equipment performance evaluation screen. When the property-specific button B18 is pressed, the equipment selection field R3 displays the names of the air conditioning equipment installed in the air conditioning systems of each property 2A, 2B, and 2C by property. FIG. 21 is a diagram showing a second example of the equipment selection field R3 on the left side of the equipment performance evaluation screen. When the equipment type button B19 is pressed, the equipment selection field R3 displays the names of the air conditioning equipment installed in the air conditioning systems of each property 2A, 2B, and 2C by equipment type. When the user of terminal 4 selects the air conditioning equipment to be displayed in a list on the equipment performance evaluation screen, he/she clicks the name of the air conditioning equipment in the equipment selection field R3. When the name of the air conditioning equipment in the equipment selection field R3 is clicked, terminal 4 adds the clicked air conditioning equipment to the list on the equipment performance evaluation screen. The processing of the air conditioning equipment selection operation performed in the equipment selection field R3 is mainly managed by the equipment selection reception processing unit 4A described above.

FIG. 22 is a diagram showing a second example of the equipment performance evaluation screen. When the graph button B20 is pressed on the equipment performance evaluation screen according to the first example shown in FIG. 19, for example, as shown in the center of FIG. 22, the performance evaluation results of the air conditioners are displayed in the form of a graph. There are three types of graphs of the performance evaluation results of the air conditioners, which are displayed vertically. The graph displayed in the upper row is a graph with the operation years on the horizontal axis and the performance evaluation points on the vertical axis. The graph displayed in the middle row is a graph with the operation time on the horizontal axis and the performance evaluation points on the vertical axis. The graph displayed in the lower row is a graph with the start/stop count on the horizontal axis and the performance evaluation points on the vertical axis. The performance evaluation points of the air conditioners selected in the equipment selection field R3 are plotted on each graph. In addition, on each graph, a regression line (see symbol A in FIG. 22) of the plotted performance evaluation points and a horizontal line (see symbol B in FIG. 22) indicating the position where the performance evaluation points are 100% are drawn. The process of graph display performed when the graph button B20 is pressed is mainly managed by the above-mentioned graph display processing unit 4B. FIG. 22 shows an example of a regression line, but a regression curve may also be used.

In the equipment performance evaluation screen shown in FIG. 22, the performance evaluation points of all the air conditioners selected in the equipment selection field R3 are displayed on a graph with the time-dependent element on the horizontal axis. The graph also displays a regression line of the plotted performance evaluation points. Furthermore, the air conditioners whose performance evaluation points are to be plotted on the graph can be selected regardless of whether they are installed in each of the properties 2A, 2B, and 2C. Therefore, for example, if the performance evaluation point of a specific air conditioner is inferior to the performance evaluation points of the air conditioners of other properties, the user of the terminal 4 can easily find out this superiority or inferiority and start verifying the suitability of the facility operation of the specific air conditioner. In addition, in the equipment performance evaluation screen shown in FIG. 22, buttons for transitioning to a hierarchical graph display screen (FIG. 11), a category graph display screen (FIG. 12), an equipment operation status system diagram (FIG. 14), and an equipment diagnosis result list screen (FIG. 16) may be provided. Then, the characteristics, power consumption, status, and corresponding model of the air conditioner displayed on this equipment performance evaluation screen are displayed on the transition screen. By configuring it in this way, you can get a comprehensive overview of the status of air conditioning equipment installed in multiple properties, and then immediately grasp the detailed status of each individual piece of air conditioning equipment installed in each property, making it easy to identify equipment that is the target of maintenance proposals or equipment upgrades.

The information processing system 1 described above allows a comprehensive overview of the status of the air conditioning equipment installed in each property 2A, 2B, and 2C, making it easy to detect the presence or absence of problems with equipment operation that may be lurking in the air conditioning equipment of a specific property, and makes it possible to take specific measures, such as leveling out operating times, prioritizing the operation of equipment with better performance, and changing settings to reduce the number of starts and stops.
