<Embodiment 1>
FIG. 1 is a functional block diagram of the environment management system according to the first embodiment. In the first embodiment, the amount of greenhouse gas generated by operating the air conditioner 50 that is an environmental control device disposed in the department 2 is calculated, and the amount of greenhouse gas generated is calculated by the information terminal 40. The case of monitoring will be described. Note that greenhouse gases include carbon dioxide, methane, dinitrogen monoxide, HFC (hydrofluorocarbon), PFC (perfluorocarbon), SF ₆ (sulfur hexafluoride), and the like. In this embodiment, various data processing is performed assuming carbon dioxide as a greenhouse gas.

  As shown in the figure, the environment management system 1 includes an environment management device 20 and an information terminal 40 disposed in a department 2, and an environment management server 30 disposed in the management center 3, each of which is a LAN 10 serving as a communication means. Are connected so as to be able to communicate with each other.

  Specifically, the environment management apparatus 20 is an information communication device having various functions of a general computer, measures the power consumption of the air conditioner 50, and uses the power consumption data that is the measured value of this power consumption. The acquired power consumption data acquisition means 21, the temperature or humidity of the department 2 adjusted by the air conditioner 50 are measured, and the environmental data acquisition means 22 acquires the environmental data that is the measured value, and the power consumption data And data transmission means 23 for transmitting environment data to the environment management server 30 via the LAN 10.

  Note that a temperature sensor, a humidity sensor, or an illuminance sensor can be used as the environmental data acquisition unit 22.

  The environmental management device 20 collects power consumption amount data representing the amount of power consumed by operating the air conditioner 50 and environmental data related to the temperature or humidity of the department 2, and is collected in the environment management server 30 via the LAN 10. Sent. The period for collecting various data may be a fixed period or an irregular period. Here, these various data are data information as shown in Tables 1 and 2, for example. In the example shown in Table 1, the amount of power consumed by the air conditioner 50 is shown, and in the example shown in Table 2, the temperature or humidity of the department 2 is shown.

  On the other hand, the environment management server 30 is an information communication device having various functions of a general computer, and stores power consumption amount data and environment data received from the environment management device 20 via the LAN 10 in association with the air conditioning device 50. From the database 31, the greenhouse gas generation amount calculating means 32 for calculating the greenhouse gas generation amount data by multiplying the greenhouse gas emission coefficient representing the generation amount of the greenhouse gas per power consumption, and the environmental control device characteristic data An upper limit set value calculating means 34 for calculating an upper limit set value that is an upper limit of the set value of the environmental control device corresponding to the predetermined greenhouse gas generation amount, and the calculated greenhouse gas generation amount data, the upper limit set value, and the database Data distribution means 33 for distributing the power consumption data and the environmental data stored in 31 to the information terminal 40 via the LAN 10; It is provided.

Here, the greenhouse gas emission coefficient refers to the amount of greenhouse gas emission per electric power consumption. For example, in the case of carbon dioxide, using a greenhouse gas emission coefficient of 0.378 (the unit is “kgCO ₂ / kWh”), 0.0756 (1 hour) from the power consumption data of the air conditioner 50 shown in Table 1 It can be calculated that kgCO ₂ ) of carbon dioxide is discharged.

  The environmental control device characteristic data is data representing a relationship between a set value for controlling the environmental control device and the amount of greenhouse gas emitted by the environmental control device when operating at the set value. Specifically, it is a correspondence table between the set temperature of the air conditioner 50 and the amount of greenhouse gas generated at this set temperature. For example, Table 3 exemplifies environmental adjustment device characteristic data. If the outside air temperature is about 10 ° C., as shown in Table 3, the load on the air conditioner 50 increases as the set value is increased, and the amount of greenhouse gas generated increases accordingly.

  The environmental control device characteristic data can be created by measuring the power consumption when the air conditioner 50 is operated at a certain set value and multiplying the power consumption by a greenhouse gas emission coefficient.

  The predetermined greenhouse gas generation amount is, for example, an upper limit value of the greenhouse gas generation amount discharged by the department 2 and is set in the environment management server 30 in advance. This is set, for example, when complying with the greenhouse gas emission standards for the environment. Furthermore, the upper limit set value of the environmental control device refers to a set value that generates greenhouse gas below the predetermined greenhouse gas generation amount. Specifically, from the amount of greenhouse gas generated in the environmental control device characteristic data, search for the amount that is less than or equal to the specified amount of greenhouse gas generated, and set the set value corresponding to the amount of generated greenhouse gas to the upper limit set value. And For example, when the predetermined greenhouse gas generation amount is 0.070, the set value corresponding to the generation amount of greenhouse gas of 0.070 or less is 18 ° C. from the environmental control device characteristic data shown in Table 3, and this value Is the upper limit setting value. That is, by setting the air conditioner 50 at this upper limit set value, the amount of greenhouse gas generated by operating the air conditioner 50 in the department 2 can be made to be a predetermined value or less.

  The environmental management server 30 accumulates the power consumption data and environmental data of the department 2 in the database 31 and centrally manages the data so that it can be viewed from the information terminal 40. A set value and greenhouse gas generation amount data are provided to the information terminal 40.

  The database 31 is not limited to the case where the hard disk of the environment management server 30 is executed as a storage medium, and may be executed by another computer. In this case, data is input / output to / from the environment management server 30 via an open data base connectivity (ODBC) or a database connection driver unique to the RDBMS.

  Further, regarding the exchange of various data with the information terminal 40, the environment management server 30 expresses various data using HTML (Hyper Text Markup Language), and uses HTML (Hyper Text Transfer Protocol) in HTML. You may comprise so that it may function as a web server which transmits / receives the various data represented. Thereby, in the information terminal 40, various data can be browsed by using a general web browser, and it is possible to avoid the burden of separately installing a special application.

  The information terminal 40 is an information communication device having various functions of a general computer, acquires power consumption data, environmental data, or greenhouse gas generation data from the environmental management server 30 via the LAN 10, and displays Displayed on a display device.

  Next, a series of operations of the environment management system 1 in the first embodiment will be described. FIG. 2 is a diagram illustrating an outline of a processing procedure of the environment management system according to the first embodiment.

  As shown in the figure, first, the environment management apparatus 20 measures the power consumption of the air conditioner 50 by the power consumption data acquisition means 21 and acquires the power consumption data. Similarly, the environment management apparatus 20 acquires the environmental data by detecting the temperature or humidity of the department 2 by the environmental data acquisition means 22, and these power consumption amount data and environmental data are sent to the environmental management server 30 by the data transmission means 23. Transmit (S1). The transmission of these data may be one in which the environment management server 30 periodically polls the environment management apparatus 20 or may be periodically transmitted from the environment management apparatus 20 to the server.

  Next, the environment management server 30 stores the received power consumption data and environment data in the database together with the received time. For example, it is stored as shown in Tables 4 to 5.

  Next, the environmental management server 30 calculates the greenhouse gas generation data by multiplying the power consumption data by the greenhouse gas emission coefficient, and generates the greenhouse gas together with the previously acquired power consumption data and the environmental data. The quantity data is transmitted to the information terminal 40 (S3). This greenhouse gas generation amount data represents the amount of greenhouse gas generated when the air conditioner 50 consumes electric power. For example, from the power consumption data shown in Table 3, the amount of greenhouse gas generation can be calculated as shown in Table 6.

  Next, the environmental management server 30 determines whether or not the amount of greenhouse gas generation calculated in the process of S3 exceeds a predetermined value (S4). If it exceeds, the upper limit set value is calculated. It transmits to the information terminal 40 (S5). For example, when the predetermined value of the generated amount of greenhouse gas is 0.0700, data of 18 ° C. is transmitted to the information terminal 40 as the upper limit set value from the environmental control device characteristic data shown in Table 3.

  Finally, the information terminal 40 receives the greenhouse gas generation amount data, the power consumption amount data, the environmental data, or the upper limit set value and displays them on the display device (S6). The environment management server 30 may periodically transmit these data to the information terminal 40, or may transmit the data in response to an acquisition request for various data from the information terminal 40.

  FIG. 3 is a diagram illustrating a display example of various data by the information terminal according to the first embodiment. As shown in the drawing, the information terminal 40 displays time series data 62 of received greenhouse gas generation amount data and environmental data and a graph 61 for each time of greenhouse gas generation amount data in the display area 60 of the display device. Further, when the amount of greenhouse gas generation is equal to or greater than a predetermined value, a warning message 63 for transmitting the upper limit set value as the set value of the air conditioner 50 for setting the predetermined value or less is displayed. Thereby, since the user of the information terminal 40 can grasp | ascertain the relationship between the present temperature of the department 2 and the generation amount of greenhouse gas, he can deepen recognition of the problem of global warming. Furthermore, when the amount of greenhouse gas generation exceeds a predetermined value, it is displayed at which setting value the air conditioning equipment should be operated in order to reduce the amount of greenhouse gas generation. The user can be motivated to set the temperature according to this set value.

<Embodiment 2>
In the second embodiment, similarly to the first embodiment, the greenhouse gas generation amount data is calculated and displayed from the power consumption data of the environmental control device, and whether or not the greenhouse gas generation amount data is equal to or greater than a predetermined value. Based on this, an embodiment of the environment management system 100 in the case of controlling the environmental adjustment device will be described.

  FIG. 4 is a functional block diagram of the environment management system according to the second embodiment. Of the configuration of the environment management system 100 according to the second embodiment, description of components having the same reference numerals as those of the environment management system 1 described in the first embodiment is omitted.

  The difference between the environmental management system 100 and the environmental management system 1 is that the first air conditioner 51, the first information terminal 41, and the first environment management device 200 are in the first department 4, the second air conditioner 52, the first In the configuration in which the second information terminal 42 and the second environmental management apparatus 201 are arranged in the second department 5, the amount of greenhouse gas generated by the environmental management server 30 when each air conditioner operates is a predetermined value. In the case described above, the set value of each air-conditioning device is controlled so that the amount of greenhouse gas generation is less than or equal to a predetermined value.

  The first environment management device 200 includes an environment adjustment device control unit 24 that controls the first air conditioning device 51 so as to operate with the set value received from the environment management server 30 via the LAN 10. The second environment management apparatus 201 has the same configuration as the first environment apparatus 400, and includes an environmental control device control means, a power consumption data acquisition means, an environmental data acquisition means, and a data transmission means ( Neither of them is shown), and the second air conditioning device 52 is controlled by the setting value received from the environment management server 30 by the environment adjusting device control means.

  In addition, the environmental management server 30 calculates the greenhouse gas generation amount data based on the power consumption data acquired from the first or second environmental management devices 200 to 201 via the LAN 10, and the first or second environmental management server 30 Each air conditioner is controlled so that the amount of greenhouse gas generated by the air conditioners 51 to 52 is less than or equal to a predetermined value.

  FIG. 5 is a diagram illustrating an outline of a processing procedure of the environment management system according to the second embodiment. A process for controlling the first and second air conditioners 51 to 52 will be described with reference to FIG. In addition, since the same process is performed about what is attached | subjected with the code | symbol same as FIG. 2 of Embodiment 1, detailed description is abbreviate | omitted.

  As illustrated, the first environment management apparatus 200 measures the power consumption of the first air conditioner 51 and acquires power consumption data. Similarly, the environmental data acquisition unit 22 detects the temperature or humidity of the first department 4 to acquire environmental data, and transmits the power consumption data and the environmental data to the environmental management server 30 by the data transmission unit 23. (S1). Next, the environmental management server 30 stores the received power consumption data and environmental data in the database together with the received time (S2), and multiplies the power consumption data by the greenhouse gas emission coefficient to generate greenhouse gas. Quantity data is calculated (S3). The second environment management apparatus 201 also performs the process of S1 and transmits the power consumption data and the environment data to the environment management server 30. The environment management server 30 performs the processes of S2 and S3 on these data, and the greenhouse gas. Generate amount data.

  In the second embodiment, it is assumed that the first air conditioner 51 and the second air conditioner 52 are set to operate at 20 ° C., respectively. Assume that the greenhouse gas generation amount data is calculated as illustrated in Table 7 at the stage where each air conditioning device is operated with such a set value and the processing of S1 to S3 is completed.

  Next, the environmental management server 30 determines whether or not the amount of greenhouse gas generation calculated in the process of S3 exceeds a predetermined value (S4). If it exceeds, the upper limit set value is calculated. The upper limit setting value is transmitted to the first and second environment management devices 200 to 201 (S7), and the first and second environment management devices 200 to 201 operate so as to operate at the received upper limit setting value. The air conditioners 51 to 52 are controlled.

  For example, when the predetermined value of the generation amount of greenhouse gas is 0.750, as shown in Table 7, each air conditioner generates greenhouse gas exceeding this predetermined value. Therefore, the environment management server calculates the upper limit set value as 18 ° C. from the environment adjusting device characteristic data shown in Table 3, and operates each air conditioner with this set value.

  In addition, it is not limited to the case where a predetermined value of the amount of greenhouse gas generated is set for each department, so that the total amount of greenhouse gas generated, which is the sum of the amount of greenhouse gas generated by each department, falls within the predetermined value Alternatively, the upper limit set value may be calculated to set the temperature of each air conditioner. This is useful when, for example, there is a situation in which the room temperature must be kept at 20 ° C. in the second department 5.

  Specifically, the following processing is performed. First, it is assumed that the predetermined value of the total amount of greenhouse gas generated by operating each air conditioner in the first to second departments 4 to 5 is 0.15. When the total greenhouse gas generation amount data is calculated from the greenhouse gas generation amount data of each air conditioner shown in Table 7, it is 0.1554 at 12:00 and becomes a predetermined value or more.

  The excess that exceeds the predetermined value of the total greenhouse gas generation data is calculated, and the setting value of the first air conditioner 51 is changed so as to reduce the excess. In this case, since the excess is 0.0054 (0.1554-0.15), the amount of greenhouse gas generated by at least the first air conditioner 51 is 0.0701 (0.0756-0.005) or less. The upper limit set value is calculated so that Since 18 ° C. can be calculated as the upper limit setting value from the environmental adjustment device characteristic data in Table 3, this upper limit setting value is transmitted to the first environment management device, and the setting value of the first air conditioning device 51 is changed. Control to do.

  As described above, by setting a predetermined value for the amount of greenhouse gas generated, each air conditioner can be controlled so as not to exceed the predetermined value.
