Description

  The present invention relates to a comfort evaluation support apparatus and method for supporting an evaluation of the comfort of an evaluation target space using a target space for air conditioning control in an office building or factory as an evaluation target space.

  Conventionally, in a space subject to air conditioning control in an office building or factory, it is required to secure a comfortable indoor environment with as little energy consumption as possible.

  However, there is a trade-off between saving energy and ensuring a comfortable indoor environment. If priority is given to energy saving, the indoor environment deteriorates and there are more hot / cold complaints from people in the room, improving the indoor environment. If the number of complaints from the occupants is reduced, the energy used will increase.

  Therefore, for example, in Patent Document 1, complaint data regarding the indoor environment from a occupant is acquired, and a PMV (Predicted Mean Vote) is calculated as data representing the comfort level of the target space for air conditioning control at the time of the complaint. The ratio of the number of complaints is obtained for each unit width for classifying the size of each and is displayed as air conditioning control support data. Accordingly, it is possible to determine a PMV that can save energy while considering comfort and set it as a target value of PMV.

  Note that PMV is an index (comfort index) indicating the comfort level of the indoor environment, and is called a thermal environment index. This PMV was proposed by Mr. Fanger. According to the comfort equation presented by Mr. Fanger, the comfort level is 7 levels (+3: hot, +2: warm, +1: slightly warm, 0: neither. -1: slightly cool, -2: cool, -3: cold). When the value of PMV is 0, it becomes comfortable.

  FIG. 12 shows a display example of air-conditioning control support data when the unit width for classifying the size of the PMV is 0.1 and the ratio of the number of claims for each unit width is replaced with the number of claims. In this example, the number of complaints is counted for each unit width (0.1) for PMV in the range of 0.1 to 0.7, and the number of complaints is displayed as air conditioning control support data. From this air-conditioning control support data, when the PMV is 0.3 to 0.5, the number of complaints is large, and the PMV that can save energy while considering comfort by avoiding the PMV section with many complaints. It can be seen that it may be set as the target value of PMV.

  However, since the number of complaints increases or decreases according to the air conditioning time in the target space for air conditioning control, there is a problem that the complaints are concentrated on the PMV having a long generation time, thereby hindering the determination of the target value of PMV. That is, even if a PMV has a short generation time, if the number of complaints per unit time is large, the number of complaints collected is small even though the PMV becomes a PMV that is most likely to generate a complaint. May be set as a target value.

  The present invention has been made to solve such a problem, and the object of the present invention is to save energy in consideration of comfort even when the generation time of comfort index such as PMV is biased. It is an object of the present invention to provide a comfort evaluation support apparatus and method capable of providing accurate information.

In order to achieve such an object, the present invention provides a comfort index measuring unit that measures data representing the comfort level of the evaluation target space as a comfort index, and a unit width for classifying the size of the comfort index. For each unit width of the comfort index, the generation time counting means for counting the occurrence time of the measured comfort index, the claim data acquiring means for acquiring the claim data for the indoor environment from the occupants in the evaluation target space, Claim frequency calculating means for calculating the number of complaints from the acquired complaint data, calculating the complaint frequency from the occurrence time of the comfort index calculated for each unit width of the comfort index and the total number of claims further comprising a calculation unit, a complaint often display means for displaying the time of occurrence of comfort index calculated by claims frequency and aggregated per unit width comfort index And features.

According to the present invention, for example, when the comfort level index is a thermal environment index (PMV), the measured PMV generation time for each unit width (for example, 0.1) that classifies the size of the PMV. Are counted. Moreover, the claim data with respect to the indoor environment from the occupant in the evaluation target space is acquired, and the number of claims is totaled for each unit width of the PMV. Then, for example, the claim frequency is calculated as the number of claims divided by the occurrence time of PMV from the occurrence time of PMV totaled for each unit width of PMV and the number of claims totaled for each unit width of PMV. The frequency of complaints and the total PMV occurrence time are displayed for each unit width of the PMV. In this case, the claim frequency indicates the number of claims per unit time, and is provided as accurate information for energy saving while considering comfort. This makes it possible to accurately evaluate the comfort even when the PMV generation time is biased.

In the present invention, the data indicating the comfort level (comfort level index) is not limited to PMV, and may be a room temperature, a discomfort index, an effective temperature, or the like.

  In the present invention, the number of occupants in the evaluation target space is acquired, and the generation time of the comfort index calculated for each unit width of the comfort index and the total for each unit width of the comfort index. From the number of claims made and the number of acquired occupants, for example, the complaint frequency per occupant may be calculated as the number of complaints divided by the occurrence time of PMV / the number of occupants.

According to the present invention, the time of occurrence of the comfort index is calculated for each unit width of the comfort index, the number of claims is calculated for each unit width of the comfort index, and is calculated for each unit width of the comfort index. The claim frequency is calculated from the time of occurrence of the calculated comfort index and the number of claims totaled for each unit width of the comfort index, and the claim frequency and total for each unit width of the calculated comfort index are calculated . Since the generation time of the comfort index is displayed, the complaint frequency for each unit width of the comfort index is provided as accurate information to save energy while considering comfort, and the PMV generation time is biased Even if it is, it becomes possible to evaluate comfort comfortably.

  In this air conditioning control system, the user terminals 3-1 to 3-6 are connected to the air conditioning operation device 2 via the communication line 5, and the PMV of the control target space 1 measured by the comfort sensor 4 is the air conditioning operation device. Is given to 2.

  In addition, the user terminals 3-1 to 3-6 include a hot / cold complaint data input unit for the control target space 2, and the complaint data from the input unit adds the generation time of the complaint data and performs an air conditioning operation. It is given to the device 2.

  Further, the air conditioning operation device 2 collects PMV from the comfort level sensor 4 as data (comfort level data) representing the comfort level of the control target space 2 at a predetermined cycle, and stores the collected PMV. Yes. In this example, the PMV collection period is, for example, 1 minute.

  FIG. 2 shows a functional block diagram of the air conditioning operation device 2. The air conditioning operation device 2 is realized by hardware including a processor and a storage device, and a program that realizes various functions in cooperation with these hardware, and includes an air conditioning operation schedule acquisition unit 21 and a comfort level data acquisition unit. 22, a claim data acquisition unit 23, a comfort level generation unit 24, a complaint count unit 25, a claim frequency calculation unit 26, and a claim frequency display unit 27. The air conditioning operation device 2 corresponds to the comfort evaluation support device according to the present invention. In this embodiment, the comfort level sensor 4 is a constituent element of the air conditioning operation device 2.

  Hereinafter, according to the flowchart shown in FIG. 3, functions unique to the present embodiment of the air conditioning operation device 2 will be described.

  In the air conditioning operation device 2, the air conditioning operation schedule acquisition unit 21 acquires the air conditioning operation schedule of the day determined in advance at the time of startup once a day (step S101). For example, for each air conditioner provided for the control target space 1, obtain an operation schedule of the air conditioner (7:00 start-17:00 stop, 7:15 start-17:10 stop, etc.) The air conditioning operation schedule for the day is created from the acquired operation schedule of each air conditioner. The air conditioning time zone in the control target space 1 indicated by the air conditioning operation schedule on that day is the evaluation target time zone.

  When the air-conditioning operation schedule for the day is started (YES in step S102), the comfort level data acquisition unit 22 starts acquiring PMV from the comfort level sensor 4 at regular intervals (step S103). The PMV acquired by the comfort level data acquiring unit 22 is sent to the comfort level occurrence time counting unit 24. The comfort level occurrence time counting unit 24 counts the acquired (measured) occurrence time of the PMV for each unit width of the PMV (step S104). FIG. 4 is a graph showing the PMV occurrence time aggregated for each unit width of the PMV. In this example, one unit width of PMV is 0.1.

  If the complaint data acquisition unit 23 acquires the complaint data from the user terminals 3-1 to 3-6 during the counting of the measured PMV occurrence times (YES in step S105), the complaint data is stored in the complaint count counting unit 25. Sent to. The claim count totaling unit 25 counts the number of claims from the acquired claim data for each unit width (every 0.1) of the PMV (step S106). FIG. 5 is a graph showing the number of claims totaled for each unit width of PMV.

  The number of claims per unit width of the PMV counted by the claim count totaling unit 25 is sent to the claim frequency calculating unit 26. When the number of complaints per unit width of the PMV is sent, the complaint frequency calculation unit 26 takes in the generation time of the PMV for each unit width of the PMV from the generation time aggregation unit 24 of the comfort level, = Claim frequency per unit width of PMV is calculated as number of claims ÷ PMV occurrence time (step S107).

  The complaint frequency for each unit width of the PMV calculated by the complaint frequency calculation unit 26 and the PMV generation time for each unit width of the PMV calculated by the comfort time generation unit 24 are sent to the complaint frequency display unit 27. It is done. The complaint frequency display unit 27 displays the complaint frequency from the complaint frequency calculation unit 26 and the PMV generation time from the comfort time generation unit 24 on the vertical axis with PMV as the horizontal axis (step S108). FIG. 6 shows a display example for each unit width of the PMV of the claim frequency and the PMV occurrence time. In the figure, a graph indicated by a bar indicates the claim frequency, and a graph indicated by a broken line indicates the PMV occurrence time.

  The air conditioning operation device 2 repeats the processing operations in steps S103 to S108 until the air conditioning operation schedule ends (YES in step S109), that is, until the air conditioning time zone (evaluation target time zone) ends. Thereby, every time the complaint data from the user terminals 3-1 to 3-6 is acquired, the complaint frequency for each unit width of the PMV is calculated in real time, and the calculated complaint frequency and the occurrence time of the PMV are graphed. Will be displayed.

  In this way, in the present embodiment, the claim frequency (number of claims ÷ PMV occurrence time) is displayed for each unit width of PMV as information for energy saving in consideration of comfort. . This claim frequency indicates the number of claims per unit time, and is provided as accurate information for energy saving in consideration of comfort. This makes it possible to accurately evaluate the comfort even when the PMV generation time is biased.

  That is, referring to the claim frequency graph shown in FIG. 6, the claim frequency is highest when PMV is 0.6 (section of 0.6 ± 0.05), and PMV is 0.1 (0.1 It can be seen that the frequency of complaints is the lowest in the range of ± 0.05). Accordingly, by avoiding PMVs with a high complaint frequency and determining PMVs that can save energy while considering comfort, PMVs that are likely to cause complaints are set as target values for PMVs. Nothing will happen. For example, according to the number of claims shown in FIG. 5, PMV = 0.6 may be set as the target value of PMV. However, according to the claim frequency shown in FIG. It is not set as the target value of PMV.

[Embodiment 2]

  In addition, as shown in the functional block diagram of FIG. 8, the air conditioning operation device 2 receives the information on the room entry / exit from the room entry / exit management device 6 and acquires the number of people in the control target space 1 every moment. A room occupancy acquisition unit 28 is provided. The number of occupants in the room acquired by the occupant number acquisition unit 28 is sent to the complaint frequency calculation unit 26.

  In this air conditioning control system, the claim frequency calculation unit 26 in the air conditioning operation device 2 includes the number of claims per unit width of the PMV from the claim count totaling unit 25 and one unit of PMV from the comfort time occurrence time totaling unit 24. From the generation time for each width and the number of occupants in the control target space 1 from the occupancy acquisition unit 28, the claim frequency = the number of claims ÷ the generation time of the PMV ÷ the number of people in the room Calculate the complaint frequency per occupant per unit width.

  The claim frequency calculated by the claim frequency calculation unit 26 for each unit width of the PMV and the occurrence time of the PMV for each unit width of the PMV calculated by the comfort time generation unit 24 are the claim frequency. It is sent to the display unit 27. The claim frequency display unit 27 displays PMV from the complaint frequency calculation unit 26 per person in the room and the PMV generation time from the comfort time generation unit 24 on the vertical axis with PMV as the horizontal axis.

  In this case, the number of people in the room for each unit width of the PMV is an average value of the number of people in the room during the generation time of the PMV for each unit width. Thereby, the generation time of PMV for each unit width is weighted by the number of people in the room, and comfort can be determined with high accuracy.

  In the second embodiment, the number of occupants in the control target space 1 is obtained from the entry / exit information from the entry / exit management device 6, but the number of occupants is estimated from the working hours. Or the number of people in the room based on the number of logged-in personal computers, or the number of people in the room based on the number of operating devices (lighting, air conditioners, VAVs, etc.) May be.

  In the first and second embodiments described above, PMV is used as data representing the comfort level of the control target space 2, but room temperature, discomfort index, effective temperature, etc. may be used instead of PMV.

In addition, the effective temperature referred to in the present invention includes a corrected effective temperature, and the concept of the discomfort index referred to in the present invention includes humidity.

  FIGS. 9 to 11 show views corresponding to FIGS. 4 to 6 when the room temperature is used instead of PMV. In this case, as shown in FIG. 11, the complaint frequency for each unit width of the room temperature and the generation time of the room temperature are displayed on the vertical axis with the room temperature as the horizontal axis. In this example, one unit width of the room temperature is set to 0.5 ° C.

  In the first and second embodiments described above, when displaying the claim frequency, “hot” / “cold” are displayed separately as the claim type, or “very hot” / “slightly hot” etc. as the degree of claim May be displayed separately.

  For example, when displaying “hot” / “cold” separately, “hot” is displayed in red and “cold” is displayed in blue. As a result, when the room temperature is used as data representing the comfort level, the manager can determine the room temperature at which the number of people who feel uncomfortable becomes the minimum number of persons.

  In addition, when displaying “very hot” / “somewhat hot”, the density of the color is changed and displayed. As a result, when the room temperature is used as data representing the comfort level, the manager can determine the room temperature that can be allowed by the occupant. For example, if energy saving is particularly important, a further energy saving effect can be achieved by setting “a little hot”.
