Description

  The present invention relates to a set temperature recommendation method and apparatus for recommending, as a set temperature, an indoor temperature at which a resident is least likely to feel dissatisfied in a tenant building or the like.

Conventionally, in a tenant building or the like, a building administrator defines a set temperature (target temperature) for a living space (temperature setting target space). For example, set the control temperature t _BL in consideration of the running cost, it has set this control temperature t _BL as a target temperature tsp (e.g., see Patent Document 1).

In this case, residents, or feel hot in the management temperature t _BL administrator of the building has been set, or feel cold. If they feel such dissatisfaction and are unable to tolerate, the resident will call the building manager over the phone and complain. The building manager responds to the resident's request by changing the management temperature in response to the complaint.

Japanese Patent No. 3457554

However, the temperature setting method for a conventional living space, has priority control temperature t _BL, which is determined in consideration of the running cost, it is modified control temperature t _BL to meet the demands of the residents, the next day It is also returned to its original management temperature t _BL to. As a result, complaints similar to those on the previous day will occur on the next day, residents will be distrusted by the building manager and the building owner, and the building manager will respond to complaints that are repeated daily. Chased.

  The present invention has been made to solve such problems, and the object of the present invention is to minimize the dissatisfaction of the resident, the distrust that the resident has, and the claim that the manager of the building is chased It is an object of the present invention to provide a method and an apparatus for recommending a set temperature that can reduce the temperature.

In order to achieve such an object, the present invention includes a step of detecting the temperature of the temperature setting target space as an indoor temperature, an opinion indicating dissatisfaction given by a resident in the temperature setting target space, and the indoor temperature at that time. Are stored in the memory in association with each other, and the opinions from the occupants stored in the memory and the indoor temperature at that time are totaled, and the indoor temperature at which the occupants in the temperature setting target space feel the least dissatisfied. And a step of presenting as a recommended value of the set temperature for the temperature setting target space.
According to this invention, the opinion indicating the dissatisfaction given by the resident in the temperature setting target space and the indoor temperature at that time are associated with each other and stored in the memory, and the opinion from the resident stored in this memory and the time at that time And the indoor temperature at which the resident in the temperature setting target space is least likely to be dissatisfied is presented as a recommended value of the set temperature for the temperature setting target space.

For example, in the present invention, hot / cold opinions given by residents are stored in a memory in association with the room temperature at that time. Then, the number of cases given the opinion of hot and the number of cases given the opinion of cold were calculated for each temperature range, and the ratio of the number of cases given the opinion of hot to the total number of cases for each temperature range ( Identified by the intersection of the broken line connecting the number of cases given the opinion of cold and the number of cases given the opinion of cold to the total number of cumulative values for each temperature range (cumulative percentage of opinion of cold) The room temperature to be set is presented as a recommended value of the set temperature for the temperature setting target space.
In this case, the indoor temperature specified by the intersection of the polygonal line connecting the cumulative percentage of opinion of hot and the polygonal line connecting the cumulative percentage of opinion of cold is most likely to be dissatisfied by residents in the temperature setting target space. The room temperature is low. Therefore, if this room temperature is set to the set temperature for the temperature setting target space, it becomes possible to minimize the dissatisfaction of residents.

In the present invention, the recommended value of the set temperature may be corrected based on the predicted outside air temperature on the day. For example, if the maximum value of the predicted outside temperature of the day is obtained from weather forecast data, and if the maximum value of the predicted outside temperature of the day is 2 ° C higher than the normal temperature, the recommended value of the set temperature is set to 0.5 ° C. If the maximum value of the predicted outside temperature on the day is 2 ° C. lower than the normal temperature, correction such as increasing the recommended value of the set temperature by 0.5 ° C. is performed. The correction may be performed by comparing the lowest expected outside air temperature on the day with the normal temperature, or may be corrected using the temperature of the previous day instead of the normal temperature.
Note that the present invention can also be configured as an apparatus to which the above-described method is applied.

According to the present invention, the opinions from the occupants and the indoor temperature at that time are tabulated, and the indoor temperature that the occupants feel most unsatisfied is presented as a recommended value of the set temperature for the temperature setting target space. Therefore, by setting the recommended value of the set temperature as the target temperature, the dissatisfaction of the occupants can be minimized, and the distrust that the occupants have and the complaints that the building manager is chased can be reduced. become able to.
Further, by correcting the recommended value of the set temperature based on the predicted outside air temperature on the day, it is possible to minimize this against the resident's dissatisfaction that changes at the outside air temperature.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an example of an air conditioning system including a set temperature recommendation device used in the practice of the present invention. In the figure, 1 is a living space (temperature setting target space) in a tenant building, 2 is an air conditioner provided for the living space 1, 3 is a temperature sensor that detects the temperature of the living space 1 as an indoor temperature tpv, 4 Is a personal computer (personal computer) used by residents in the living space 1, 5 is a data collection device, 6 is a central device (set temperature recommendation device) provided in the monitoring room of the tenant building, and the air conditioner 2 and temperature The sensor 3, the personal computer 4, the data collection device 5 and the central device 6 are connected to each other by a network (LAN) 7.

  In this air conditioning system, the data collection device 5 collects and accumulates the indoor temperature tpv of the living space 1 detected by the temperature sensor 3 at a cycle of 1 minute. The air conditioner 2 inputs the set temperature (target temperature) tsp sent from the central device 6 and the indoor temperature tpv of the living space 1 detected by the temperature sensor 3, and the living space so that tsp = tpv. Control the supply air temperature to 1.

  FIG. 2 shows an outline of the hardware configuration of the central device 6. In the figure, 6-1 is a CPU, 6-2 is a RAM, 6-3 is a ROM, 6-4 is a storage device such as a hard disk, 6-5 to 6-7 is an interface, 6-8 is a display, 6- 9 is a keyboard, and 6-10 is a mouse. The CPU 6-1 obtains various input information given via the interfaces 6-5 to 6-7, and operates according to the program stored in the ROM 6-3 or the storage device 6-4 while accessing the RAM 6-2. .

The storage device 6-4 stores a recommended set temperature presentation program for presenting a recommended set temperature value to the building administrator as a program unique to the present embodiment. The recommended set temperature presentation program is provided in a state where it is recorded on a recording medium such as a CD-ROM, for example, and is read from the recording medium and installed in the storage device 6-4.
Hereinafter, the processing operation performed by the CPU 6-1 by the set temperature recommended value presentation program described above will be described with reference to the flowcharts shown in FIGS.

  In the living space 1, if the resident feels hot / cold dissatisfaction, the resident sends the hot / cold opinion from the personal computer 4 to the central device 6 via the network 7. For example, there is a menu called an opinion box on the screen of the personal computer 4, and a hot / cold item in the opinion box is checked and transmitted to the central device 6.

  When the CPU 6-1 of the central device 6 receives a hot / cold opinion (claim) from the personal computer 4 (FIG. 4: YES in step 401), the latest indoor temperature tpv is obtained from the data collecting device 5 as the indoor temperature at that time. The acquired room temperature tpv is associated with the complaint contents and stored in the storage device 6-4 (step 402). As a result, as shown in FIG. 3, the storage device 6-2 accumulates a hot / cold opinion from a resident and a room temperature tpv when the opinion is given as a pair.

  In this embodiment, the room temperature when the opinion of hot / cold is given from the living space 1 is acquired from the data collecting device 5, but the room temperature tpv at that time is directly acquired from the temperature sensor 3. You may make it do. Since the data collection device 5 collects the indoor temperature tpv at a cycle of 1 minute, the indoor temperature tpv acquired from the data collection device 5 has a delay of 1 minute at the maximum. On the other hand, if it is obtained directly from the temperature sensor 3, the room temperature tpv at the same time as when a hot / cold opinion is given can be obtained.

  Next, the CPU 6-1 adds up the hot / cold opinions from the resident accumulated in the storage device 6-4 and the room temperature at that time, and gives the number of hot opinions given and the opinion of cold. The obtained number is obtained for each predetermined temperature range, and this is graphed and displayed on the display 6-8 (step 403). Moreover, the recommended value (recommended temperature) of the setting temperature with respect to the living space 1 is displayed in the graph (step 404).

  FIG. 6 illustrates a graph (temperature setting support graph) displayed on the display 6-8. In this temperature setting support graph G, the horizontal axis represents the room temperature, and the vertical axis represents the number of hot / cold opinions. The vertical axis also represents the cumulative percentage (%) of the number of hot / cold opinions. The CPU 6-1 obtains the number of cases given the opinion of being hot accumulated in the storage device 6-4 for each 0.5 ° C. width, and displays it as a bar graph indicated by a mesh line in the figure. Further, the number of cases given the opinion of cold accumulated in the storage device 6-4 is obtained for each 0.5 ° C. width, and this is displayed as a bar graph shown in white in the figure.

  Further, the CPU 6-1 determines the ratio of the cumulative value for each temperature range of the number of cases given the opinion of hot to the total number of cases [cumulative ratio of hot opinion: (cumulative value of hot opinion / total number of hot opinions). ) × 100 (%)] is displayed. Also, the ratio of the number of cases given the opinion of cold to the total number of cumulative values for each temperature range [cumulative percentage of opinions of cold: (cumulative value of opinions of cold / total number of opinions of cold) x 100 (% )] Is displayed. In addition, the room temperature specified by the intersection P1 between the polygonal lines C1 and C2 is a numerical value as a recommended value of the set temperature for the living space 1, that is, as the indoor temperature at which the resident in the living space 1 is least likely to feel dissatisfied. indicate.

  The temperature setting support graph G is updated every time a resident gives a hot / cold opinion. That is, every time a resident gives a hot / cold opinion, the number of hot opinions and the number of cold opinions change, and along with this, the polygonal lines C1 and C2 indicating the cumulative ratio are displayed. change. Thereby, the recommended value of the set temperature for the living space 1 also changes. In the present embodiment, the building manager changes the current set temperature tsp in response to a resident's request when a resident receives a hot / cold opinion.

  FIG. 7 illustrates a temperature setting support graph G after one year has elapsed from the start of operation. From the temperature setting support graph G after one year has passed, it can be seen that the room temperature at which the complaint that it is hot is higher than the room temperature at which the complaint that it is cold is higher, but it tends to overlap. Further, it can be seen that at a room temperature of 24 ° C., a complaint that about 20% is hot and a complaint that about 50% is cold are issued. In addition, at 24.6 ° C, the recommended temperature, the percentage of complaints about hot and the percentage of complaints about cold are almost the same, and this is the room temperature where residents are least likely to feel dissatisfied. I understand that.

  The manager of the building checks the temperature setting support graph G displayed on the display 6-8 of the central device 6 every morning and considers whether the recommended temperature displayed in the graph G is used, the running cost, etc. The CPU 6-1 is instructed whether to use the management temperature (initial value) determined as described above. For example, if the management temperature is used due to a request from the owner, an instruction to use the initial value is given to the CPU 6-1. When an instruction to use the initial value is given (FIG. 5: YES in step 501), the CPU 6-1 sends the management temperature (initial value) to the air conditioner 2 as the set temperature tsp (step 508).

  When an instruction to use the recommended temperature is given (YES in step 502), the CPU 6-1 acquires the recommended temperature (recommended value of the set temperature) displayed in the graph G (step 503), An inquiry is made to the building administrator as to whether or not to correct the outside air temperature (step 504). Here, if an instruction that the outside air temperature correction is not necessary is given by the building manager (NO in step 504), the CPU 6-1 uses the recommended temperature acquired in step 503 as the set temperature tsp to the air conditioner 2. Send (step 507).

  On the other hand, when an instruction that the outside air temperature correction is necessary is given by the building administrator (YES in step 504), the CPU 6-1 corrects the recommended temperature acquired in step 503 (step 503). 505). In this case, as the outside air temperature correction, the maximum value of the predicted outside temperature of the day is obtained from the weather forecast data. Lower 5 ° C. If the expected maximum outside air temperature on the day is 2 ° C lower than the normal temperature, the recommended temperature is increased by 0.5 ° C. Then, the CPU 6-1 sends the corrected recommended temperature to the air conditioner 2 as the set temperature tsp (step 506).

  In the above-described embodiment, the same temperature support setting graph G is updated throughout the year. For example, the beginning of April to the end of October is the cooling time, and the beginning of November to the end of March is the heating time. It is also possible to divide the year into graphs for cooling and heating and update the respective graphs (temperature setting support graph during cooling, temperature setting support graph during heating). In this case, if it enters at the time of cooling, it will update from the temperature setting assistance graph at the last cooling of last year, and if it enters at the time of heating, it will update from the temperature setting assistance graph at the last heating of last year. FIG. 8 illustrates a temperature setting support graph GA during cooling, and FIG. 9 illustrates a temperature setting support graph GB during heating.

  In the above-described embodiment, the room temperature specified by the intersection P1 between the polygonal lines C1 and C2 in the temperature setting support graph G is numerically displayed as the recommended temperature. The room temperature specified by the intersection P1 of the polygonal lines C1 and C2 may be read by the building manager. Further, without displaying the broken lines C1 and C2, only the room temperature specified by the intersection of the broken lines C1 and C2 may be displayed numerically. Displaying a bar graph indicating the number of hot / cold opinions and a line of cumulative percentage makes it easier to understand intuitively. In addition, when the recommended value of the set temperature is displayed numerically, it is possible to save the administrator of the building from reading the graph one by one.

  In the embodiment described above, when the outside temperature correction is performed, the maximum value of the predicted outside temperature on the day is acquired from the weather forecast data, and the maximum value of the estimated outside temperature on the acquired day and the normal temperature are acquired. However, the correction is made by comparing the lowest expected outside temperature of the day with the normal temperature, or using the previous day's temperature instead of the normal temperature. Or you may.

  In the above-described embodiment, the number of living spaces is one in order to simplify the description, but there are a plurality of living spaces in the tenant building. Even when there are a plurality of living spaces, the present invention can be applied in the same manner as described above. FIG. 10 shows a configuration example of a system when there are a plurality of living spaces. In this example, there are four living spaces 1-1 to 1-4, and air conditioners 2-1 to 2-4 and temperature sensors 3-1 to 3-4 are provided for the living spaces 1-1 to 1-4. Is provided. In this case, on the screen of the central device 6, the living spaces 1-1, 1-2, 1-3, 1-4 are shown in FIGS. 11 (a), (b), (c), (d), for example. The temperature setting support graphs G1, G2, G3, G4 as shown are displayed. The manager of the building determines whether or not to use the recommended temperature (recommended value of the set temperature) displayed in these graphs G1, G2, G3, and G4 as the set temperature tsp. Further, it is determined whether or not to perform outside temperature correction.

  In the above-described embodiment, the building administrator is made to determine whether or not to use the suggested recommended value of the set temperature and whether or not the outside air temperature correction is performed. Without any doubt, the recommended value of the presented set temperature is set as the set temperature tsp, or the recommended value of the set temperature corrected for the outside air temperature is set as the set temperature tsp, so that it is immediately sent from the central device 6 to the air conditioner 2. Good. For example, the recommended value of the set temperature is obtained once every morning, not every time the opinion of hot / cold is given, or the recommended value of the set temperature corrected for the outside air temperature is obtained, and the recommended set temperature is obtained. The value is set as the set temperature tsp and sent immediately from the central device 6 to the air conditioner 2. In this case, the recommended value of the set temperature is not presented to the building manager, but is presented to the means for transmitting the set temperature in the central device 6, and such a presentation is also defined as a presentation definition in the present invention. Is included.

  In the embodiment described above, the hot / cold opinion is sent to the central device 6 using the personal computer 4. However, a dedicated user terminal is provided for each living space 1, and the user terminal is connected to the central device 6. You may send hot / cold opinions. In addition, one person in charge of transmitting the hot / cold opinion to the central device 6 may be performed on behalf of the resident in the living space 1, but each resident in the living space 1 individually You may make it carry out.

  In addition, instead of using a personal computer or a user terminal, the building manager may be notified of hot / cold opinions by telephone. In this case, the manager of the building accepts hot / cold opinions from the residents, and manually inputs the opinions and the times when the opinions were present into the central device 6. The central device 6 stores the hot / cold opinion manually input by the building manager in the storage device 6-4 in association with the room temperature tpv at the time when the opinion was made. In this case, the CPU 6-1 of the central device 6 acquires the room temperature tpv at the time when there is an opinion from the data collection device 5.
