Description

  The present invention relates to an information calculation apparatus and control program for an air conditioning system that air-conditions a plurality of conditioned rooms with a plurality of indoor units.

An air conditioning system that air-conditions a plurality of conditioned rooms with a plurality of indoor units includes a function that apportions the total power consumption transmitted from the main power meter for each indoor unit (for example, a patent) Reference 1), the usage fee of each indoor unit can be calculated from this apportionment result. For this reason, when this air conditioning system is installed in a school, office building, etc., the room to be conditioned is obtained by determining the power consumption of the indoor unit belonging to the room to be conditioned (for example, a room for each classroom or department). It is possible to know the power consumption required for each air conditioning.
JP 2005-241189 A

By the way, in recent years, there has been a demand for promotion of energy saving (so-called energy saving) against the background of environmental problems, and as part of this, the degree of energy saving (hereinafter referred to as energy saving) is determined for each conditioned room, and this is determined for each harmonized room. Competing with each other will help promote energy conservation.
However, if the degree of energy saving is expressed in terms of power consumption, differences in conditions for each room to be conditioned (differences in the size and position of the room to be conditioned, differences in the number of people in the room to be tuned, etc.) have a significant effect on the increase or decrease in power consumption. Therefore, it is not a numerical value that fully reflects the effort or contribution of energy conservation by the personnel in the harmonized room.
For example, even if multiple classrooms have the same power consumption, classrooms with high air conditioning load, such as a large air-conditioned space or a large number of people in the room, should have a higher energy-saving effort (energy conservation contribution). A numerical value capable of appropriately determining this is desired.

  Then, an object of this invention is to provide the information calculation apparatus and control program of an air conditioning system which can calculate the numerical value with high reflection degree of an energy-saving effort.

  In order to solve the above-described problem, the present invention provides information on an air conditioning system including a plurality of indoor units arranged in a plurality of conditioned rooms, and a temperature setting device that sets a set temperature of each indoor unit. The calculation device is connected so as to be able to acquire set temperatures of the plurality of indoor units, acquires the set temperature in the conditioned room in which the indoor unit is in operation, and the acquired set temperature is preset. A value obtained by accumulating a numerical value obtained by converting the score based on the recommended set temperature for each of the conditioned rooms is calculated. According to the present invention, since the numerical value obtained by converting the acquired preset temperature based on the preset recommended preset temperature is cumulatively added for each conditioned room, a numerical value with a high degree of reflection of energy saving efforts can be calculated. .

In the above configuration, when the indoor unit is in operation, the numerical value converted from the set temperature is added, and when the indoor unit is in operation stop, a numerical value assigned in advance to the operation stop is added. It may be. According to this configuration, when it is considered that the indoor unit does not use air conditioning while the operation is stopped and the energy saving degree is high, a numerical value reflecting this can be calculated.
In the above configuration, the recommended set temperature may be changed based on at least one of a calendar, a time, and an outside air temperature. According to this configuration, the change in the score due to the change in the set temperature that directly affects the calendar, time, or outside temperature can be offset by the change in the recommended set temperature, and the influence of the calendar, time, or outside temperature can be offset. Reduced point conversion is possible.

  Further, in the above configuration, a terminal communication unit for communicating with a terminal connected to a predetermined communication line via the communication line, the terminal communication unit is provided for each of the conditioned rooms via the communication line. The cumulative addition result may be output to the terminal. According to this configuration, it is possible to check a tracking addition result by operating a terminal connected to a predetermined communication line.

  Further, the present invention is a control program for an air conditioning system comprising a plurality of indoor units arranged in a plurality of conditioned rooms, and a temperature setting device for setting a set temperature of each indoor unit, and a computer In addition, the set temperature in the conditioned room being operated by the indoor unit is acquired, and a numerical value obtained by converting the acquired set temperature based on a preset recommended set temperature is cumulatively added for each conditioned room. A value is calculated. According to the present invention, since the numerical value obtained by converting the acquired preset temperature based on the preset recommended preset temperature is cumulatively added for each conditioned room, a numerical value with a high degree of reflection of energy saving efforts can be calculated. .

  According to the present invention, the numerical value obtained by converting the acquired set temperature based on the recommended set temperature set in advance is cumulatively added for each conditioned room, so that a numerical value with a high degree of reflection of energy saving efforts can be calculated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

When it demonstrates separately, it describes with 10A of 1st air conditioning apparatuses, the 2nd air conditioning apparatus 10B, and the 3rd air conditioning apparatus 10C.

Each air conditioner 10 includes a plurality of (or even one) outdoor units 15 having a compressor, an outdoor heat exchanger, and an outdoor fan, an indoor heat exchanger, and an indoor fan. This is a multi-type air conditioner in which a plurality of indoor units 20 installed in a conditioned room are connected by inter-unit piping 25. Each air conditioner 10 causes each outdoor unit 15 to function as a condenser and each indoor unit 20 as an evaporator during cooling operation, and conversely, during each heating operation, each outdoor unit 15 serves as an evaporator and each indoor unit 20. Is functioned as a condenser to cause each indoor unit 20 to perform a cooling operation or a heating operation.
In addition, the outdoor unit 15 and the indoor unit 20 of each air conditioner 10 are configured to be communicably connected via the sub-communication line 6, and more specifically, an outdoor control device (not configured) provided in the outdoor unit 15. And an indoor control device (not shown) provided in the indoor unit 20 are communicably connected via the sub communication line 6. As a result, the outdoor control device controls each part of the outdoor unit 15 and gives various instructions to the indoor control device to control each part of the indoor unit 20.

  In each conditioned room (classroom), a remote control device 30 as an operation device operated by a user is installed. By each remote control device 30, air conditioning operation / stop, set temperature setting, wind speed, etc. Various operations are possible. More specifically, the remote control device 30 is connected to the indoor unit 20 by wire or wirelessly, and when the remote control device 30 is operated, a transmission signal is output from the remote control device 30 and the indoor control of the indoor unit 20 is performed. It is received by the apparatus and transmitted from the indoor unit 20 to the outdoor control device of the outdoor unit 15 via the sub communication line 6. Then, under the control of the outdoor control device, the operation / stop is controlled for each indoor unit 20 according to the operation of the remote control device 30. In the case of operation, an indoor temperature sensor (not connected) provided on the indoor unit 20 side is controlled. The air-conditioning operation (air-conditioning capability, air volume, etc.) is controlled based on the difference between the room temperature acquired from the figure) and the set temperature set via the remote control device 30 or the like. That is, the remote control device 30 functions as a temperature setting device that sets at least a set temperature for each room to be conditioned.

  In the plurality of air conditioners 10, the number of indoor units is set according to the configuration of the facility (school) (number of classrooms, size, number of buildings, etc.). In the case of this configuration, the first air conditioner 10A allows one outdoor unit 15 and seven indoor units 20 to be connected via the inter-unit piping 25 and to be communicably connected via the first sub communication line 6A. The second air conditioner 10B is configured to be connected, and one outdoor unit 15 and six indoor units 20 can be connected to each other via the inter-unit pipe 25 and connected via the second sub communication line 6B. The third air conditioner 10C is configured to connect one outdoor unit 15 and four indoor units 20 with inter-unit piping 25 and communicate with each other via the third sub communication line 6C. Connected and configured. Moreover, although this example demonstrates as what each indoor unit 20 is installed in each to-be-harmonized room, you may install 2 or more units. In addition, these air conditioning apparatuses 10 can apply widely well-known air conditioning apparatuses, such as an electric heat pump type and a gas heat pump type.

  The control computer 50 functions as a centralized control device that performs integrated monitoring and control of each air conditioner 10, and more specifically, various controls (run / stop, run) for each indoor unit 20 individually or in groups. Mode (cooling / heating, etc.), wind speed, set temperature, etc.), and various monitoring of each indoor unit 20 individually or in groups (operation / stop, operation mode (cooling / heating, etc.), wind speed, setting Temperature). Hereinafter, the configuration of the control computer 50 will be described.

  FIG. 2 is a block diagram showing a functional configuration of the control computer 50. The control computer 50 is configured using a general computer system having a CPU, a ROM, a RAM, and the like, and includes a control unit 51 as a control / calculation unit, and a storage unit that stores various programs and data executed by the control unit 51. 53, an air conditioning side communication unit 55 for communicating with the air conditioner 10 via the main communication line 2, and an Internet communication unit for communicating with an external terminal via an Internet communication network (wide area communication line) (not shown). (Terminal communication unit) 57. Here, the Internet communication unit 57 can widely apply publicly known communication means for accessing the Internet communication network via the main communication line 2 or another communication line (not limited to wired communication but also wirelessly). Corresponds to, for example, a personal computer (hereinafter referred to as a school terminal) having an Internet connection function installed in a school where the air conditioning system 1 is installed.

The storage unit 53 includes a control program 100 for integrated monitoring and control of each air conditioner 10, air conditioning system basic data 102, and history data 110. The air conditioning system basic data 102 includes indoor unit data 104 that is basic data of each indoor unit 20 of each air conditioner 10 and outdoor unit data 106 that is basic data of each outdoor unit 15.
The indoor unit data 104 includes, for each indoor unit 20, the type (model, etc.) of the air conditioners 10A, 10B, 10C to which the indoor unit 20 belongs, and the installation location (information for identifying the conditioned room (classroom, etc.)). The presence / absence of the remote control device 30, the indoor unit address (unique identification number), and the like are associated with each other, and the air conditioner 10 defines an indoor unit group. This indoor unit group is used for group control of a plurality of indoor units 20, and the indoor addresses of the indoor units 20 belonging to the group are registered for each indoor unit group.
Further, in the indoor unit data 104, specific settings (for example, temperature setting, wind direction setting, air volume setting, etc.) for the indoor unit 20 are controlled by the control computer 50, and an operation from the remote control device 30 for the specific settings is performed. Central control information for prohibiting is included. This centralized control information is classified into a plurality of centralized control modes according to the type of specific setting that prohibits the operation from the remote control device 30, and to which centralized control mode each indoor unit 20 to be centralized control is assigned. It is recorded whether it is classified.

The outdoor unit data 106 is associated with each outdoor unit 15 such as the type of the air conditioning system to which the outdoor unit 15 belongs, the outdoor unit address (unique identification number), and the like. The history data 110 is a history of calculation results and the like obtained by the control computer 50 performing information calculation processing described later.
Under the above configuration, the control computer 50 refers to the information described in the air conditioning system basic data 102 to send an instruction to each air conditioner 10 via the air conditioning side communication unit 55, and each outdoor unit 15. In addition, the air conditioning operation of the indoor unit 20 is centrally controlled, and the information on the operation state (operation / stop, set temperature, etc.) of each unit 15, 20 is collected from each air conditioner 10 via the air conditioning side communication unit 55. Can do.

By the way, when trying to quantify the energy saving level for each conditioned room using this type of control computer, if the numerical value of power consumption for each conditioned room is used, the difference in conditions ( Differences in the size and position of the harmony room (per day), the number of people in the room to be harmonized, etc., have a significant effect on the increase or decrease in power consumption, so the energy saving efforts and contributions of the people in the room to be harmonized are fairly and fully reflected. It does not become a numerical value.
On the other hand, when the energy saving degree is expressed by the degree of use of the indoor fan (average rotation speed and power consumption) obtained as a result of the personnel in the conditioned room operating the remote control device 30, the energy consumption of the indoor fan Since only a small percentage of the total energy consumption is shown, this figure does not accurately reflect energy saving efforts.
Accordingly, the inventors have noted that the set temperature of the conditioned room has a large effect on the energy consumption and is highly reflective of energy saving efforts, and saves energy based on the set temperature for each conditioned room. A numerical value indicating the degree (hereinafter referred to as an evaluation value) is calculated.

  In the present embodiment, the control computer 50 having a central control function capable of collecting information such as the set temperature of each indoor unit 20 calculates information for calculating an evaluation value indicating the degree of energy saving based on the set temperature for each conditioned room. The processing is further performed. Therefore, in the control program 100 of the control computer 50, in addition to the basic program for realizing the function of the centralized control device for integrated monitoring and control of the air conditioners 10, an optional program for performing the information calculation process Is included, so that the processing as the centralized control device and the information calculation processing can be executed in parallel. This optional program is a program installed in the control computer 50 according to the desire of the user (in this example, the school side), thereby simplifying the calculation processing function in addition to the basic function as the centralized control device. It is configured so that it can be added.

FIG. 3 is a flowchart of the information calculation process. This process is a process that is selectively executed in accordance with the use / non-use setting of the optional function set by the user (school side). When the use is set, the air conditioner 10 Regardless of operation / stop, it is always executed at a predetermined interrupt cycle. In the following description, the control computer 50 does not prohibit the operation of each air conditioner 10 from the remote control device 30, and each conditioned room is controlled by the remote control device 30 in each conditioned room (classroom). It is assumed that the set temperature (hereinafter referred to as set temperature T1) of the room (classroom) can be arbitrarily set, and the air conditioning operation start / stop (operation start / stop of the indoor unit 20) can be operated. In other words, it is assumed that a person in the room to be harmonized (students in the classroom, etc.) operates the air conditioning operation / stop and sets or changes the set temperature T1.
In addition, for the conditioned room where the operation from the remote control device 30 is prohibited, the information calculation for each tuned room described below may or may not be performed. It can be set.

First, when this information calculation process is performed, a recommended set temperature TX is set (step S1). This recommended set temperature TX is a recommended set temperature when air conditioning each conditioned room (classroom). In this embodiment, the set temperature is set to 24 ° C. during cooling and set to 22 ° C. during heating. This setting may be a default value set when the air conditioning system 1 is installed, or may be input and set appropriately by a user or the like.
In this process, the recommended set temperature TX is used as a reference value for converting the set temperature T1 into a numerical value indicating the degree of energy saving. Here, FIG. 4 shows an example of a point conversion table during cooling, and FIG. 5 shows an example of a point conversion table during heating. As shown in FIG. 4 and FIG. 5, when the set temperature T1 is the same as the recommended set temperature TX, 0 points are set, and if the set temperature T1 is on the energy saving side, points are added (positive values). For example, when the set temperature T1 is 26 ° C. which is 2 ° C. higher than the recommended set temperature TX during cooling, a +2 point is set (see FIG. 4), and the set temperature T1 is set higher than the recommended set temperature TX during heating. If it is 20 degrees C lower by 2 degrees C, it is set as +2 points.
Further, if the set temperature T1 is on the energy wasting side, a negative value, that is, a deduction point, and the deduction point value is also set to a larger value as the energy wasting side. For example, during cooling, the set temperature T1 is higher than the recommended set temperature TX. If it is 22 ° C., which is 2 ° C. lower, it is −2 points (see FIG. 4). The data of such a score conversion table is stored in the storage unit 53 in a data format such as table data in which the difference between the set temperature T1 and the recommended set temperature TX is associated with the score, or a calculation formula, for example. By using this data, the control unit 51 of the control computer 50 can convert the set temperature T1 into points.

Here, returning to FIG. 3 again, the outline of the subsequent processing of this information calculation processing will be described. The control unit 51 of the control computer 50 acquires the set temperature T1 of the indoor unit 20 during the air conditioning operation (step S2). The acquired set temperature T1 is converted into points (step S3), and each point is cumulatively added for each conditioned room (step S4), and the process is repeated. That is, the control computer 50 accumulates and adds a numerical value related to the set temperature T1 for each conditioned room (classroom) in which the indoor unit 20 is operating for each conditioned room.
Further, when the indoor unit 20 is stopped in the air conditioning operation in the process of step S2, a numerical value assigned in advance to the air conditioning stop is set, and this is cumulatively added. In the present embodiment, the numerical value assigned in advance to the stop of air conditioning is regarded as a high degree of energy saving (3 points in this example) because air conditioning is not used and the degree of energy saving is high.

  6A is a diagram illustrating an example of scores for a plurality of classrooms A to F, and FIG. 6B is a diagram illustrating a score calculation result. In this figure, the air conditioning status of each classroom A to F will be briefly described. Class A shows a case where the set temperature T1 is set to the recommended set temperature TX and the air conditioning operation is performed, and classrooms B and C show the set temperature T1. Indicates the case where the air conditioning operation is performed by setting the energy saving side with respect to the recommended set temperature TX, and the classrooms D and E indicate the case where the air conditioning operation is performed with the set temperature T1 set on the energy wasting side than the recommended set temperature TX, Only classroom E has been air-conditioned since 8 o'clock. Moreover, the classroom F has shown the case where almost no air-conditioning driving | operation is carried out.

  As shown in FIG. 6 (A), the point conversion is performed once every hour from 7 am to 8 am, once from 8 am to 9 am, and so on. Yes. In this case, the point is converted with the minimum value of the set temperature T1 within that time (within 1 hour) during cooling, and the point is converted with the maximum value of the set temperature T1 within that time during heating. The reason for this is that when the set temperature T1 is momentarily changed to the energy saving side, if the score is converted with the set temperature T1, the energy saving evaluation value becomes a high score. This is because, as described above, the points are converted based on the set temperature T1 that is set most on the energy wasting side within a predetermined time, so that it is possible to avoid a case that differs greatly from the actual situation.

As a result of the calculation from 7:00 am to 11:00 for classrooms A to F, as shown in the left column of FIG. 6B, the score is as follows: classroom C> classroom B = classroom F> classroom A > Classroom D> Classroom E was obtained.
As described above, classrooms B and C that are air-conditioned by setting the set temperature T1 to the energy-saving side, that is, the scores of classrooms B and C that make energy-saving efforts clearer than others, are high. On the other hand, the scores of classrooms D and E in which the preset temperature T1 is set on the energy wasting side and the air conditioning operation is performed are low, and the scores reflecting the energy saving efforts of each classroom can be obtained.
In addition, when the air conditioning is stopped, since the energy saving degree is high, a high score is given. Therefore, the classroom F in which the air conditioning operation is hardly performed has a relatively high score. Here, when the classroom F is in a situation where the classroom F is being used by a student, it is considered that the student's energy saving efforts are extremely high, so the above score is a value that appropriately reflects this situation. I know that.

Here, the left column of FIG. 6B shows the progress from 7:00 am to 11:00 am, and the right column is the cumulative addition of the hourly score from 7:00 am to 7:00 am the next day. The score data for one day is shown in 24 hours. The control unit 51 cumulatively adds the hourly score for each room to be harmonized (classroom), and score data for one day in 24 hours (SA point, SB point, SC point, SD point, SE point, SF point) Are stored in the storage unit 53 as the history data 110, and the cumulative added value of the scores is stored on a daily basis. As a result, score data (accumulated addition result) for each day for each room to be harmonized (classroom) is accumulated in the history data 110.
In addition, the control unit 51 receives various instructions from an external terminal (school terminal or the like) connected to the Internet communication network via the Internet communication unit 57, and refers to the history data 110 according to this instruction and requested. The score data of the room to be harmonized (classroom) or the graphed result is transmitted, or the result is summed up and the result is transmitted so that the external terminal can confirm the result. In short, the external terminal can browse the calculation result of the control computer 50 using browser software.
In addition, when the control computer 50 is directly operated, the control unit 51 outputs the counting result (including the intermediate progress) to an output device (display device, printing device, etc.) connected to the control computer 50. be able to. As a result, the score result for each room to be harmonized (classroom) can be easily obtained and confirmed.

As described above, in the present embodiment, the set temperature T1 of the indoor unit 20 in operation is acquired, and a value obtained by accumulating a numerical value obtained by converting the set temperature T1 into points for each conditioned room is calculated. Therefore, it is possible to calculate an evaluation value reflecting the energy saving effort in which the set temperature T1 is set on the energy saving side.
Moreover, since the set temperature T1 is converted into points based on a predetermined recommended set temperature, it can be converted into a numerical value that can accurately determine whether the set temperature T1 is on the energy saving side, and an evaluation value that more appropriately reflects energy saving efforts Can be. As a result, it becomes possible to appropriately evaluate the energy saving efforts of each harmonized room based on this evaluation value, and for the energy saving competition between classrooms or departments such as schools or commercial buildings where the air conditioning system 1 is installed. It is possible to calculate a suitable evaluation value.
Furthermore, since an external terminal connected to the Internet communication network can view the calculation result of the evaluation value of the control computer 50 of the air conditioning system 1, the evaluation value for each conditioned room can be easily confirmed using existing equipment. For example, students in each classroom in the school can operate the terminal at school or at home to check whether the evaluation value of their classroom is currently higher or lower than other classrooms become.

  The best mode for carrying out the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the above-described embodiment, when air conditioning is stopped (air conditioning OFF), a case where a high score is given has been described as an example, but this score may be changed as appropriate according to the actual situation. For example, if the reason for stopping the air conditioning is simply that there are no personnel in the conditioned room, it is not an energy saving effort, so it is desirable that there be no additional points (zero points). As a specific example, in the case of a school, when there is an outdoor class such as physical education, it is inevitable that the class period is in an air-conditioning stop (air-conditioning OFF).

Here, FIGS. 7A and 7B show a case in which FIGS. 6A and 6B have no additional points (zero added points) when air conditioning is stopped (air conditioning OFF). As shown in this figure, since the period of air conditioning operation (air conditioning ON) is different for each conditioned room (classroom), the cumulative number N of scores differs for each conditioned room (classroom). In classrooms A to D, the cumulative addition number N is 3, the classroom E is 4 times, and the classroom F is 1 time.
Therefore, the longer the period of air conditioning operation (air conditioning ON), the higher the possibility that the cumulative addition value (Score) will fluctuate greatly. In other words, the longer the period of air conditioning stop (air conditioning OFF), the longer the cumulative addition value. (Score) is a small value (a value close to zero). For this reason, the reason why the air-conditioning is stopped (air-conditioning OFF) is long because the outdoor lesson is long, and even when the energy saving efforts are not made, the cumulative added value falls within a relatively small value.
For this reason, in the direct comparison of the cumulative added value, the reason why the classroom F is in the air conditioning stop (air conditioning OFF) is long is simply that there are no personnel in the classroom, and the set temperature T1 is most wasted during the air conditioning operation. Despite less energy-saving efforts on the side, there is a situation in which classroom E has a lower score than classroom F.

Therefore, when there is no possibility that the air conditioning is stopped (air conditioning OFF) is not an energy saving effort, as shown in the right column of FIG. 7B, the score used for competition is the cumulative added value (Score). An average cumulative addition value (average Score) divided by the cumulative addition number N is used.
As a result, the average cumulative added value (score) is obtained as follows: Class C> Class B> Class A> Class D> Class E> Class F That is, the classroom F that does not make the most energy-saving efforts becomes the lowest, and a score that reflects the actual energy-saving efforts can be obtained. In this case, the daily score data may be a value obtained by multiplying the average cumulative addition value (average Score) by 24 times.

Moreover, although the case where a user etc. set the recommended setting temperature TX to a fixed value was demonstrated in the above-mentioned embodiment, it is not restricted to this, The control part 51 of the control computer 50 is any one of calendar, time, or outside temperature. The recommended set temperature TX may be changed based on the above.
For example, as a change mode according to the calendar, the recommended set temperature TX during cooling operation is increased when the average temperature is high, and the recommended set temperature TX during cooling operation is decreased when the average temperature is low, and recommended during heating operation. The set temperature TX is preferably reversed. Moreover, as a change mode according to the time, a mode in which the recommended set temperature TX is changed separately in the morning, noon, night and time zone is considered, and as a change mode by the outside air temperature, the recommended setting at the time of cooling is higher as the outside air temperature is higher An embodiment in which the temperature TX is increased is conceivable.
If the recommended set temperature TX is changed in this way, the change in the score due to the change in the set temperature T1 caused directly by the influence of the calendar, time or outside temperature can be offset by the change in the recommended set temperature TX. The point conversion which reduced the influence of time or outside temperature can be performed.

Further, in the above-described embodiment, when there are a plurality of indoor units 20 in the conditioned room and each of the set temperatures T1 can be set individually, the set temperatures T1 of the plurality of indoor units 20 belonging to the same conditioned room Of these, the set temperature T1 that is the least energy-saving may be converted into points, or the average value of these set temperatures T1 may be converted into points.
In the above-described embodiment, the case where the cumulative addition value is totaled every day has been described. However, the present invention is not limited to this. In this case, when the ranking of the previous day is low, the ranking can be recovered by changing the set temperature T1 to the energy saving side thereafter.
Further, the point conversion formula for the set temperature T1 may be arbitrarily set or may be set individually for each conditioned room. For example, separate point conversions may be performed at a store and an office. Further, the scoring interval is not limited to one hour, but may be a day unit or may be set arbitrarily.

Furthermore, in the above-described embodiment, a case has been described in which the control computer 50, which is a centralized control device, is also used as an information calculation device that calculates an evaluation value indicating the degree of energy saving. You may make it provide.
In the above-described embodiment, a case has been described in which a control program for executing the above processing is stored in advance in the apparatus. However, the control program is stored in a computer such as a magnetic recording medium, an optical recording medium, or a semiconductor recording medium. May be stored in a readable recording medium, and the computer may read and execute the control program from the recording medium. The control program may be downloaded from a distribution server on the communication network.
Further, the present invention can be widely applied to uses such as a school, an office, a chain store, etc., for energy saving competition by converting points for each room such as a classroom.
