Description

  The present invention relates to an air conditioning control technique, and more particularly to an air conditioning control technique for controlling a room to be controlled to an optimal thermal environment with less energy consumption.

  In recent years, in facilities such as buildings and factories, as part of reducing the energy consumed for facility operation, air conditioning control to reduce the energy consumption used when controlling the controlled room to the optimal thermal environment Technology is drawing attention.

  As one of such air-conditioning control technologies, the feature quantity indicating the operating status of the air-conditioning equipment, which includes the energy consumption of each equipment that makes up the air-conditioning equipment, and the temperature of the cold and hot water sent from the heat source equipment and the outside air temperature Based on the relationship between the water supply temperature and the energy consumption at the actual outside air temperature specified from this evaluation model. A so-called optimal control technique has been put into practical use in which a water supply temperature that minimizes energy consumption is specified and air conditioning control is performed using this water supply temperature as a control variable value (see, for example, Patent Document 1).

  Conventionally, in such optimal control, the supply air dew point temperature and the refrigerant bypass flow rate are monitored, and the optimal refrigerant temperature to be set is corrected according to the obtained monitoring result. A technique for setting a control range consisting of a lower limit value in advance and changing the actual refrigerant temperature by a predetermined limit only when the specified optimum refrigerant temperature is within the control range (see, for example, Patent Document 2) ) Has been proposed. Thereby, it is possible to realize stable energy saving operation while avoiding an increase in load on the load device and unnecessary activation of the heat source device.

Japanese Patent No. 5320128 JP 2013-195000 A

However, in such a conventional technique, although air conditioning control is performed using a water supply temperature (refrigerant temperature) specified from within a preset control range, the physical quantity indicating the status of the air conditioning equipment is actually monitored. Since the water supply temperature is specified based on this, the cold feeling of the user who actually uses the room to be controlled is not reflected in the air conditioning control.
For this reason, despite the air-conditioning control aiming to achieve both comfort and energy saving, the user who uses the room to be controlled is instructed to the manager of the facility to the room thermal environment. There was a problem that reports such as pleasure and requests for raising / lowering the air conditioning temperature were made.

  The present invention is for solving such problems, and an object of the present invention is to provide an air conditioning control technique capable of realizing energy saving in consideration of a user's feeling of coolness with respect to a thermal environment of a room.

  In order to achieve such an object, the air conditioning control support system according to the present invention specifies an air supply temperature of cold / hot water supplied from a heat source device to an air conditioner in consideration of energy saving from a specified control range. An air-conditioning control support system that is used together with a control device and presents an optimal control range corresponding to a feeling of coolness of a user who uses a room that is subject to air-conditioning control as the control range. The operation status DB for storing individual operation status parameter values indicating the operation status of the air conditioning equipment to be performed in chronological order, and for each declaration from the user indicating discomfort with respect to the thermal environment of the room, The operating situation parameter value is extracted from the operating situation DB, and an incident indicating an incident occurred in the air conditioning control of the room is calculated from these operating situation parameter values. An incident data generating unit that generates the event data, and the number of each incident data, the water supply temperature included in the incident data as the operating condition parameter value, and the operating condition of the air conditioner among the operating condition parameter values. The incident table creation unit creates an incident table that shows the relationship between the number of declarations made from the obtained count values and the combination of these count values, and corresponds to the specified operating condition parameter values. An optimum control range presenting unit that selects a range of the feed water temperature that has not been reported from the user from the incident table and presents the range as the optimum control range.

  In addition, according to one configuration example of the air conditioning control support system according to the present invention, when the incident table creation unit counts the number of declarations, a narrowing-down included in the operating condition parameter value from the respective incident data. Target incident data having a parameter value for operation is selected, and the number of these target incident data is counted for each combination of the water supply temperature and a parameter value for selection consisting of operating condition parameter values other than the parameter value for narrowing down. It is a thing.

  Further, in the configuration example of the air conditioning control support system according to the present invention, the optimum control range presentation unit selects from the incident table as the control range used when the air conditioning control device specifies the water supply temperature. The optimum control range is set in the air conditioning control device.

  Also, in one configuration example of the air conditioning control support system according to the present invention, the optimum control range presenting unit allows the administrator to specify the control range used when the air conditioning control device specifies the water supply temperature. As the guidance for designating, the incident table including the optimum control range is displayed on the screen.

  The air-conditioning control support method according to the present invention is used together with an air-conditioning control device that specifies the supply temperature of cold / hot water to be supplied from a heat source device to an air conditioner in consideration of energy saving from a specified control range. An air-conditioning control support method for presenting an optimal control range according to the feeling of coolness of a user who uses a room that is subject to air-conditioning control as a control range, and shows the operating status of the air-conditioning equipment controlled by the air-conditioning control device For each step of storing individual parameter values in time series by the driving status DB and reporting from the user who shows discomfort with respect to the thermal environment of the room, the driving status parameter values at the time when the reporting is made Incidents that are extracted from the situation DB and that generate incident data indicating incidents that occurred in the air conditioning control of the room from these operating condition parameter values An operation condition parameter value indicating the operation condition of the air conditioning equipment among the water supply temperature and the operation condition parameter value included in the incident data as the operation condition parameter value. The incident table creation step for creating an incident table indicating the relationship between the number of declarations obtained from the obtained count values and these combinations and the water supply temperature corresponding to the specified operating condition parameter value And an optimum control range presentation step of selecting a water supply temperature range for which there is no report from the user from the incident table and presenting the range as the optimum control range.

  According to the present invention, when the air conditioner is operated in the operation state corresponding to the specified operating condition parameter value, the water supply temperature range in which there is no report from the user indicating discomfort with respect to the thermal environment of the room is optimal. Presented as a control range. Therefore, the air-conditioning control device originally selects the water supply temperature that can achieve both comfort and energy saving from the optimal control range where no report from the user has occurred. Can be kept low. For this reason, it becomes possible to implement | achieve energy saving, considering the user's cold feeling with respect to the thermal environment of a room.

  Further, the reduction in user reports eliminates the need for the administrator to change the control range for specifying the water supply temperature. For this reason, managers struggle to respond to declarations, and in order to place more emphasis on user comfort than energy conservation, there is a significant case of stopping optimal control and returning to air conditioning control using general reference set values. As a result, the optimum control is continuously used, and as a result, an energy saving effect can be obtained over a long period of time.

[Principle of the Invention]
First, the principle of the present invention will be described.
As described above, in the conventional optimum control in the air conditioning control device, when the water supply temperature is specified based on the monitoring result of monitoring the physical quantity indicating the condition of the air conditioning equipment, the purpose is to achieve both comfort and energy saving. In spite of air conditioning control, users who use the room to be controlled report to the facility manager about discomfort with the room's thermal environment and requests for raising / lowering the air conditioning temperature. May be.

  As one of the causes of such a report from the user, it is considered that the demand for the thermal environment varies depending on the user's preference and activity, the floor usage method, the type of business of the tenant, and the like. In addition, there may be a difference in the spatial temperature distribution compared to the content set as a reference due to differences or changes in the room layout or structure. Therefore, according to the conventional optimum control, both comfort and energy saving can be achieved as a whole, but the optimum thermal environment cannot always be realized when viewing the user individually. .

  Moreover, in such optimal control, when an administrator adjusts the thermal environment of a room according to a report from a user, the control range for specifying the water supply temperature is changed. However, it is difficult for an administrator to easily and quickly specify an appropriate control range that can save energy while reducing user discomfort. For this reason, the manager has a hard time dealing with it, and in order to place more importance on the user's comfort than energy saving, the optimal control may be stopped and returned to the air conditioning control using a general reference set value. Further, when the optimum control is stopped once in this way, it is not possible to determine when the optimum control should be restored, and as a result, the optimum control is stopped for a long time.

Therefore, as a result of the analysis related to the conventional optimum control as described above, air conditioning control is supported by presenting a control range that matches the operating conditions of the air conditioning equipment, including variations in the feeling of coolness by the user. Was found to be important.
Based on such a viewpoint, the air conditioning control support system according to the present invention makes a report from a user showing discomfort with respect to the thermal environment of a room as an inappropriate driving situation in optimal control or a driving situation leading to it, that is, an incident. The water supply temperature range where these incidents have not occurred is presented as the optimum control range.

[Operation of First Embodiment]
Next, the operation of the air conditioning control support system 10 according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing the optimum control range presentation processing of the air conditioning control support system according to the first embodiment.

  When presenting the optimum control range, the air conditioning control support system 10 executes the optimum control range presentation process of FIG. 5 for each air conditioning equipment 31 in accordance with, for example, an instruction from the administrator or the occurrence of a new report. Note that the reporting data acquisition unit 14 acquires the reporting data and stores it in the reporting DB 16 in accordance with the generation of reporting data. Moreover, about the acquisition of the driving | running condition by the driving | running condition acquisition part 15, and the storing to driving | running condition DB17 shall be performed regularly.

  First, the incident data generation unit 18 selects the newly stored report data after the previous time out of the report data stored in the report DB 16, and operates at the time when the report is made for each of the report data. The situation parameter value is extracted from the driving situation DB 17. Then, incident data indicating an incident is generated from these driving condition parameter values and stored in the incident DB 19 (step 100). In addition, incident data regarding the report which occurred in the past shall already be memorize | stored in incident DB19.

Next, the operation condition acquisition unit 20 acquires the amount of load heat consumed by each air conditioner 32 that is input by the administrator from the operation input unit 12 as a narrowing parameter value (step 101).
In response to this, the incident table creation unit 21 selects target incident data having the load heat quantity indicated by the parameter value for narrowing down as the operating condition parameter value (step 102), and sets the number of selected target incident data to the maximum. Counting is performed for each combination of temperature and water supply temperature (step 103), and an incident table is created based on the number of reports obtained (step 104).

Next, the operating condition acquisition unit 20 acquires the maximum temperature in the vicinity of the air conditioning equipment 31 that has been input by the administrator from the operation input unit 12 as a parameter value for selection (step 105).
Subsequently, the optimum control range presenting unit 22 displays the range of the water supply temperature for which the number of reports is zero and the user has not reported among the water supply temperatures corresponding to the maximum temperature indicated by the parameter value for selection, in the incident table. A selection is made from the incident table created by the creation unit 21 (step 106), and the range is presented as an optimum control range to the air conditioning control device 34 via the communication I / F unit 11 (step 107). The range presentation process ends.

FIG. 6 is an example of creating an incident table (load heat amount = 5 GJ). Here, the load heat quantity = 5 [GJ] is used as a parameter value for narrowing down, and the number of times of reporting is set at the square where the maximum temperature and the water supply temperature intersect.
In this example, a plurality of ranges (ranges) in increments of 5 ° C. are set as the maximum temperature, and a plurality of ranges (ranges) in increments of 1 ° C. are set as the water supply temperatures. Therefore, incidents that match the combination of these maximum temperature range and water supply temperature range are counted as cases, and the number of declarations is shown in the intersecting grid.

For example, in an operating situation where the maximum air temperature is “30 ° C. to less than 35 ° C.” and the water supply temperature is “11 ° C. or more to less than 12 ° C.”, this indicates that the user has reported “four times” In the driving situation where the air temperature is “20 ° C. or more and less than 25 ° C.” and the water supply temperature is “10 ° C. or more and less than 11 ° C.”, it is indicated that the report from the user has not occurred.
Therefore, when 5 [GJ] is specified as the load heat quantity and “24 ° C.” is specified as the maximum temperature, the number of declarations is determined from the water supply temperature corresponding to the maximum temperature “20 ° C. to less than 25 ° C.”. Zero, that is, a water supply temperature range where no report from the user has occurred, here, “7 ° C. or more and less than 11 ° C.” is selected and presented as the optimum control range.

FIG. 7 is an example of creating an incident table (load heat amount = 10 GJ). Here, load calorie | heat amount = 10 [GJ] is used as a parameter value for refinement | miniaturization, and the frequency | count of a report is set to the square which the highest temperature and water supply temperature cross | intersect.
Also in this example, as in FIG. 6, a plurality of ranges (ranges) in increments of 5 ° C. are set as the maximum temperature, and a plurality of ranges (ranges) in increments of 1 ° C. are set as the water supply temperatures.

For example, in the driving situation where the maximum temperature is “30 ° C. to less than 35 ° C.” and the water supply temperature is “11 ° C. to less than 12 ° C.”, “−” is indicated without any case, and the maximum temperature is “20 ° C. to less than 25 ° C.” In the operation state where the water supply temperature is “10 ° C. or more and less than 11 ° C.”, it is shown that the report from the user has occurred “twice”.
Therefore, when 10 [GJ] is specified as the load heat quantity and “24 ° C.” is specified as the maximum temperature, the number of declarations is determined from the water supply temperature corresponding to the maximum temperature “20 ° C. to less than 25 ° C.”. Zero, that is, the water supply temperature range in which no report from the user has occurred, here, “7 ° C. or higher and lower than 10 ° C.” is selected and presented as the optimal control range.

[Effect of the first embodiment]
As described above, according to the present embodiment, the incident data generation unit 18 extracts the driving situation parameter value at the time of the reporting from the driving situation DB 17 for each report from the user showing discomfort with respect to the thermal environment of the room. Incident data indicating an incident that has occurred in the air conditioning control of the room is generated from these operating condition parameter values, and the incident table creation unit 21 includes the number of each incident data as the operating condition parameter value in the incident data. Counting for each combination of the water supply temperature and the operating condition parameter value, creating an incident table indicating the relationship between the obtained number of declarations and these combinations, and the optimum control range presenting unit 22 sets the specified operating condition parameter value. Based on the incident table It is obtained so as to present the optimum control range to choose from.

As a result, when the air conditioning equipment is operated in the operating condition corresponding to the specified operating condition parameter value, the range of the water supply temperature that has not been reported by the user showing discomfort with respect to the thermal environment of the room is the optimum control range. Presented.
Therefore, the air conditioning control device 34 originally selects the water supply temperature that can achieve both comfort and energy saving from the optimum control range in which no report from the user has occurred, so a report from the user occurs. The possibility can be kept low. For this reason, it becomes possible to implement | achieve energy saving, considering the user's cold feeling with respect to the thermal environment of a room.

  Moreover, according to this Embodiment, since the report from a user is reduced, it becomes unnecessary for an administrator to change the control range for specifying water supply temperature. This reduces the number of cases where managers struggle to respond to declarations and stop optimal control and return to air-conditioning control using general reference set values in order to emphasize user comfort over energy conservation. Therefore, the optimum control is continuously used, and as a result, it is possible to obtain an energy saving effect over a long period of time.

  Further, in the present embodiment, when the incident table creation unit 17 counts the number of declarations, the target incident data having the parameter value for narrowing included in the operating condition parameter value is selected from each incident data, and these You may make it count the number of object incident data for every combination of parameter value for selection which consists of operating condition parameter values other than the water supply temperature and the said parameter value for said narrowing down. As a result, the number of incident data for which the number of declarations should be counted can be reduced, the incident table scale can be reduced, and the processing burden can be reduced.

  Further, in the present embodiment, when the optimum control range presenting unit 22 presents the optimum control range, the optimum control range selected from the incident table is communicated as the control range used when the air conditioning control device 34 specifies the water supply temperature. You may make it set to the air-conditioning control apparatus 34 via the I / F part 11. FIG. As a result, the optimum control range identified by the air conditioning control support system 10 is automatically set in the air conditioning control device 34, so that the burden on the administrator for specifying the control range can be greatly reduced.

[Second Embodiment]
Next, an air conditioning control support system 10 according to the second embodiment of the present invention will be described with reference to FIG. FIG. 8 is a block diagram illustrating a configuration of an air conditioning control support system according to the second embodiment.

  In the first embodiment, the case where the air conditioning control support system 10 sets the specified optimum control range to the air conditioning control device 34 via the communication line L1 has been described as an example. In the present embodiment, a case will be described in which an incident table including the identified optimum control range is presented to the administrator by screen display.

  In other words, in the present embodiment, the appropriate control range presentation unit 22 uses the optimal control as guidance for the administrator to designate the control range used when the air conditioning control device 34 specifies the water supply temperature to the air conditioning control device 34. It has a function to display the incident table including the range in a table format. In addition, about the other structure in the air-conditioning control assistance system 10 concerning this Embodiment, it is the same as that of 1st Embodiment mentioned above, and detailed description here is abbreviate | omitted.

[Operation of Second Embodiment]
Next, with reference to FIG. 9, operation | movement of the air-conditioning control assistance system 10 concerning this Embodiment is demonstrated. FIG. 9 is a flowchart illustrating an optimum control range presentation process of the air conditioning control support system according to the second embodiment.

  When presenting the optimum control range, the air-conditioning control support system 10 executes the optimum control range presentation process of FIG. 9 for each air-conditioning facility 31 in accordance with, for example, an instruction from the administrator or the occurrence of a new report. Note that the reporting data acquisition unit 14 acquires the reporting data and stores it in the reporting DB 16 in accordance with the generation of reporting data. Moreover, about the acquisition of the driving | running condition by the driving | running condition acquisition part 15, and the storing to driving | running condition DB17 shall be performed regularly.

  First, the incident data generation unit 18 selects the newly stored report data after the previous time out of the report data stored in the report DB 16, and operates at the time when the report is made for each of the report data. The situation parameter value is extracted from the driving situation DB 17. Then, incident data indicating an incident is generated from these driving condition parameter values and stored in the incident DB 19 (step 200). In addition, incident data regarding the report which occurred in the past shall be memorize | stored in incident DB19.

Next, the operating condition acquisition unit 20 acquires the amount of load heat consumed by each air conditioner 32 input by the administrator from the operation input unit 12 as a narrowing parameter value (step 201).
In response to this, the incident table creation unit 21 selects target incident data having the load heat amount indicated by the parameter value for narrowing down as the operating condition parameter value (step 202), and sets the number of selected target incident data to the maximum. Counting is performed for each combination of air temperature and water supply temperature (step 203), and an incident table is created based on the obtained number of reports (step 204).

Next, the operating condition acquisition unit 20 acquires the maximum temperature near the air conditioning equipment 31 input by the administrator from the operation input unit 12 as an operating condition parameter value (step 205).
In response to this, the optimum control range presenting unit 22 selects the range of the water supply temperature in which the number of reports is zero and there is no report from the user among the water supply temperatures corresponding to the maximum temperature indicated by the selection parameter value, A selection is made from the incident table created by the incident table creation unit 21 (step 206).

  Thereafter, the optimal control range presenting unit 22 is an incident including the optimal control range as a guidance screen for the administrator to designate the control range used when the air conditioning control device 34 specifies the water supply temperature to the air conditioning control device 34. The table is displayed on the screen in the form of a table by the screen display unit 13 and presented to the administrator (step 207), and the series of optimum control range presentation processing is terminated.

FIG. 10 is an example of a guidance screen of the water supply temperature control range according to the second embodiment. Here, the number of declarations is set at the square where the maximum temperature and the water supply temperature intersect.
In this example, in the incident table column 41 of the guidance screen, a plurality of ranges (ranges) in increments of 5 ° C. are set as the maximum temperature, and a plurality of ranges (ranges) in increments of 1 ° C. are set as the water supply temperatures. Therefore, incidents that match the combination of these maximum temperature range and water supply temperature range are counted as cases, and the number of declarations is shown in a tabular form at the intersecting squares.

Therefore, when 15 [GJ] is specified as the load heat quantity and “24 ° C.” is specified as the maximum temperature, the number of declarations is determined from the water supply temperature corresponding to the maximum temperature “20 ° C. to 25 ° C.”. Zero, that is, a water supply temperature range in which no report from the user has occurred, here, “7 ° C. or more and less than 11 ° C.” is highlighted (indicated by a broken line) on the incident table as the optimum control range.

[Effect of the second embodiment]
As described above, in the present embodiment, the appropriate control range presentation unit 22 serves as a guidance for the administrator to specify the control range used when the air conditioning control device 34 specifies the water supply temperature to the air conditioning control device 34. The incident table including the optimum control range is displayed on the screen.
Thereby, the manager can determine the optimum control range while confirming not only the reporting status from the user at the specified maximum temperature but also the reporting status at the maximum temperature different from the specified maximum temperature. Therefore, a more appropriate control range can be determined as the control range to be set in the air conditioning control device 34 based on the viewpoint of abundant building management that the administrator has.

In this embodiment, the case where the optimum control range selected by the optimum control range presentation unit 22 is highlighted on the guidance screen has been described as an example.

In the present embodiment, a case where the operating condition acquisition unit 20 acquires the predicted maximum temperature and the predicted load heat amount from an external device via the communication I / F unit 11 will be described.

  The work for the administrator to determine the optimal control range to be set in the air conditioning control device 34 is performed before the user starts using the room in consideration of the time lag of the air conditioning control. It is necessary to set the optimal control range before the start of work in the morning. For this reason, the maximum temperature to be specified as the operating condition is a value obtained by predicting the outdoor temperature during the daytime on that day. Such a predicted value may be set by an administrator based on experience, but general weather forecast data provided from an external device can also be used.

  In addition, the amount of heat applied depends on many factors such as outside temperature, weather, weekdays, days of the week, and events. Therefore, the load heat amount to be specified as the operation condition may be set by the administrator from the viewpoint of air conditioning management, but the predicted load heat amount estimated by the external device using a known method can also be used. The present embodiment is based on such a viewpoint.

  That is, in the present embodiment, the operating condition acquisition unit 20 has a function of acquiring the predicted maximum temperature and the predicted load heat amount provided from the external device via the communication I / F unit 11 when acquiring the operating conditions.

Note that the reporting data acquisition unit 14 acquires the reporting data and stores it in the reporting DB 16 in accordance with the generation of reporting data. Moreover, about the acquisition of the driving | running condition by the driving | running condition acquisition part 15, and the storing to driving | running condition DB17 shall be performed regularly.

  First, the incident data generation unit 18 selects the newly stored report data after the previous time out of the report data stored in the report DB 16, and operates at the time when the report is made for each of the report data. The situation parameter value is extracted from the driving situation DB 17. Then, incident data indicating an incident is generated from these driving condition parameter values and stored in the incident DB 19 (step 300). In addition, incident data regarding the report which occurred in the past shall be memorize | stored in incident DB19.

Next, the operating condition acquisition unit 20 acquires the predicted load heat amount consumed by each air conditioner 32 as a narrowing parameter value from an external device (not shown) via the communication I / F unit 11 (step). 301).
In response to this, the incident table creation unit 21 selects target incident data having the predicted load heat quantity indicated by the parameter value for narrowing down as the operating condition parameter value (step 302), and determines the number of the selected target incident data. Counting is performed for each combination of maximum temperature and water supply temperature (step 303), and an incident table is created based on the number of reports obtained (step 304).

Next, the operating condition acquisition unit 20 acquires the predicted maximum temperature in the vicinity of the air conditioning equipment 31 as a selection parameter value from an external device (not shown) via the communication I / F unit 11 (step 305).
In response to this, the optimum control range presentation unit 22 selects the range of the water supply temperature in which the number of declarations is zero and the user has not reported among the water supply temperatures corresponding to the predicted maximum temperature indicated by the parameter value for selection. The incident table created by the incident table creating unit 21 is selected (step 306).

  Thereafter, the optimal control range presenting unit 22 is an incident including the optimal control range as a guidance screen for the administrator to designate the control range used when the air conditioning control device 34 specifies the water supply temperature to the air conditioning control device 34. The table is displayed on the screen in the form of a table on the screen display unit 13 and presented to the administrator (step 307), and the series of optimum control range presentation processing is terminated.

FIG. 13 is a guidance screen example of a water supply temperature control range according to the third embodiment. Here, the number of declarations is set at the square where the maximum temperature and the water supply temperature intersect.
In this example, in the incident table column 41 of the guidance screen, a plurality of ranges (ranges) in increments of 5 ° C. are set as the maximum temperature, and a plurality of ranges (ranges) in increments of 1 ° C. are set as the water supply temperatures. Therefore, incidents that match the combination of these maximum temperature range and water supply temperature range are counted as cases, and the number of declarations is shown in a tabular form at the intersecting squares.

Further, in the operation condition column 42 in the guidance screen, today's predicted maximum temperature and predicted load heat amount acquired from an external device as the operation condition parameter values, and yesterday's actual load heat amount are displayed.
