The current energy conservation law obliges the consumer sector not only to improve the energy conservation performance of individual devices, but also to conserve energy in terms of management using BEMS (Building and Energy Management System).

  However, as the actual situation of building management, the building manager does not always operate air conditioning devices such as cooling and heating appropriately from the viewpoint of comfort and energy saving. In particular, with regard to thermal environment management (for example, temperature management) of living spaces where energy saving and comfort are intricately related, a customary target temperature is set for ease of management, and it is received from users who enjoy the thermal environment. Generally, the set value is changed according to a claim.

  In other words, because temperature management is performed without fully considering the characteristics of the building or occupants, the living space is not necessarily kept in a comfortable state for the user, and furthermore, waste of energy consumed by the air conditioner occurs. There is. In addition, some users are dissatisfied with being unable to control their own thermal environment because they are in a thermal environment managed by the building manager.

In response to the problems caused by temperature management of air conditioning control, users' requests for thermal environment are collected in real time from personal computer terminals (hereinafter referred to as personal computers) operated by each individual. There is a method to set the target temperature based on the relationship between the thermal environment desired by the user and the target temperature in real time, the user characteristics that change from moment to moment, the difference between the actual temperature of the living space and the detected temperature, etc. It is possible to change the thermal environment according to the characteristics of each building. (For example, refer to Patent Document 1).

(Embodiment 1)
FIG. 1 shows a configuration of an air conditioning control system according to the present embodiment, in which one or a plurality of users exist and a thermal environment is constructed by the system (for example, a floor in a building, each room, or a wide area). Public area) Communication network NT (such as Ethernet (registered trademark)) in which air conditioning equipment 1 and air conditioning controller 2 installed in A and each user in space A input environmental information Inf indicating the current thermal environment A plurality of input devices 3 consisting of the above personal computer terminals are connected to each input device 3 via the communication network NT, and the target temperature To of the space A is set based on the thermal environment information Inf input by each user. And a central control device (hereinafter referred to as a server device) 4.

Requested strength acquisition means 42 for obtaining the desired strength Inf2 of each user based on the received environmental information Inf, normalizing means 43 for generating a weighted desired strength Inf2 ′ obtained by normalizing the desired strength Inf2, and the desired information Inf1 Then, the weighted requested strength Inf2 ′ is totaled, and based on the total content and the judgment criteria registered in the judgment criteria database 44, the target temperature To of the space A is derived, and the communication network NT is connected to the air conditioning control device 2. Control plan drafting means 45 passed through, environmental information Inf, demand information Inf1, demand strength Inf2, target temperature To Composed of the history storage means 46 for storing the history.

  As shown in FIG. 2A, the air conditioning equipment 1 used in the system of the present embodiment is installed in the air conditioning equipment room 100 in the form of cold / hot water from a heat source (not shown) consisting of a refrigerator (cooling tower) or boiler. It consists of an air conditioner consisting of an installed air conditioner 101, a duct 102 disposed in the space A, and an outlet 104, and heats and cools air (heat exchange with air) in the air conditioner 101, The heat-exchanged air is supplied into the space A from the dozen or more outlets 104 provided in the space A that is the floor of the environment control target through the duct 102. As for the return air, an air conditioner is used that secures a return air path 105 indicated by a broken line from the central passage of the space A toward the air conditioning equipment room 100, mixes the outside air at the same time, and performs air conditioning. In this air conditioning equipment, the air conditioner 101 changes the supply air temperature and controls the room temperature.

  Here, the thermal environment control target space A of the present embodiment is an office floor, for example, and a large number of desks 106 are arranged in the space A as shown in FIG. It has come to be used. In such a space A, the input device 3 which is a personal computer on the desk used by the user who enjoys the thermal environment accesses a WEB server (not shown) in the server device 4 and inputs content for inputting environmental information to the WEB. The environment information input means 31 is realized by obtaining from the server. In the illustrated example, it is assumed that a system capable of communicating with the server device 4 is constructed for all the input devices 3 via the communication network NT, and the environment information input means 31 is provided between the server device 4 and the input device 3. General browser software that realizes Each input device 3 has an air conditioning number (a number that identifies the air conditioning area of the air conditioning equipment 1) and unique identification information (for example, an individual name or an e-mail address) of the air conditioning equipment 1 as a target when inputting environmental information Etc.) and the environmental information Inf is delivered to the server device 4 together with the unique identification information and the air conditioning number.

  The server device 4 constitutes the core of the system of the present embodiment, has data acquisition timing, etc., and when each input device 3 is activated and content for entering environment information is automatically started, A function of providing necessary data to the input device 3 corresponding to the rising is provided.

  That is, the content for inputting the environment information is set to automatically start when the input device 3 is activated, and the input device 3 accesses the server device 4 at the same time when the input device 3 is activated, and a signal ( The environment information input means 31 is realized by sending necessary information such as a question format from the server device 4 side. Note that the configuration in which the input device 3 transmits a signal indicating its activation to the server device 4 is not limited to the above configuration.

  FIG. 3 shows a monitor screen after the input device 3 is activated, and the user of the input device 3 inputs the environment information Inf indicating the current thermal environment. This is a screen for selecting and inputting a request for a temperature that "I want to lower the temperature" and a comfort of "Very uncomfortable", "Uncomfortable", and "Somewhat uncomfortable". When the corresponding check fields C1 to C5 are checked using a pointing device such as a mouse and the transmission button B1 is clicked, the environment information Inf indicating the current thermal environment is displayed by the specific user at that time. The information is uploaded to the server device 4 together with the identification information and the air conditioning number. In addition, the screen for inputting the environment information Inf can be displayed on the input device 3 at an arbitrary timing not only when the input device 3 is started but also by a user operation or an instruction from the server device 4. it can. On the server device 4 side, personal attributes such as “name” and “gender” of the user in FIG. 3 are specified by this identification information.

  In this way, the server apparatus 4 processes the environment information Inf input from the input apparatus 3 according to the flowchart of FIG. First, when environmental information Inf is collected from each input device 3 in the server device 4, the request information acquisition unit 41 determines that each user's request for temperature is “temperature” from the request for temperature in the environmental information Inf. "I want you to raise the temperature" or "I want you to lower the temperature", if it is "I want to raise the temperature", the request information Inf1 is set to "+1" and "I want you to lower the temperature" If so, the request information Inf1 is set to "-1." Further, the requested strength acquisition means 42 sets the desired strength (requested strength) Inf2 for each user's temperature to any point P of “1”, “2”, and “3” based on the comfort in the environmental information Inf. If it is classified, point P is set to “1” if it is “somewhat uncomfortable”, point P is set to “2” if it is “uncomfortable”, and point P is set to “3” if it is “very uncomfortable” (step) S1). The request information Inf1 and the desired strength Inf2 of each user are sequentially stored in the history storage means 46.

  If the request information Inf1 is positive, it is a request to increase the temperature, and if the request information Inf1 is negative, it is a request to decrease the temperature. The strength of the request is determined by the magnitude of the required strength Inf2. That is, the desired strength for each user can be expressed by the desired strength Inf2.

  However, when each user inputs comfort, depending on the personality of each individual, those who are reluctant do not use “very uncomfortable” with a high demand strength, and those who have a strong self-assertion Large “very uncomfortable” tends to be frequently used, and setting both “very uncomfortable” to the same desired intensity “3” is not suitable for the purpose of this system. Similarly, “unpleasant” and “slightly uncomfortable” have different usage frequencies for each individual, and the same can be said.

  Therefore, the history storage means 46 stores a history of past requested strength Inf2 of each user (identification information), and the normalizing means 43 calculates the requested strength Inf2 for each user based on this history. Normalization is performed (step S2). This normalization process is based on the history of the appearance frequency F for the desired strength Inf2 (point P) for each user (for each identification information) shown in FIG.

The weighting factor W is derived according to For example, in FIG.

It becomes.

  Then, as shown in FIG. 6, the normalizing means 43 multiplies the desired strength Inf2 input by each user by the weighting coefficient W to calculate the weighted desired strength Inf2 '. For example, if the comfort level input by the user in FIG. 5 is “very uncomfortable”, the point P of the environmental strength Inf2 is “3”, and this point “3” is multiplied by the weighting factor W “0.52”. As a result, “1.56” is the user's desired weighting intensity Inf2 ′.

  The weighted demand strength Inf2 ′ of each user calculated in this way is also sequentially stored in the history storage means 46, and the control planning means 45 stores the latest demand information Inf1 and the weighted demand strength Inf2 ′ for each user in the history. Extracted from the means 46 is used as valid data (step S3).

  Then, the control plan drafting means 45 calculates a request rate from the effective data of each user's request information Inf1 and weighted request strength Inf2 ', and performs a process based on the agreement formation logic based on this request rate (step S4). The consensus building logic performed by the control plan drafting unit 45 will be described based on the flowchart of FIG. First, the request information Inf1 of the users H1 to H3 is “1”, that is, “I want to raise the temperature”, whereas the request information Inf1 of the user H4 is “−1”, that is, “I want to lower the temperature”. In addition, the weighting request strength Inf2 ′ of the user H1 is “1.56”, the weighting request strength Inf2 ′ of the user H2 is “1.00”, and the weighting request strength Inf2 ′ of the user H3 is “1. 50 ”, and the weighted desired intensity Inf2 ′ of the user H4 is“ 0.75 ”.

  When the requests of the users H1 to H3 are “I want to raise the temperature” and the request of the user H4 is “I want to lower the temperature”, the request rate calculated by the control plan drafting means 45 in step S21 in the flowchart is The request rate of “I want to raise the temperature” is [(1.56 + 1.00 + 1.50) / (1.56 + 1.00 + 1.50 + 0.75)], and the request rate of “I want to lower the temperature” is [(0.75 ) / (1.56 + 1.00 + 1.50 + 0.75)]. Then, the determination criteria shown in FIG. 7B are registered in the database 44, and the target temperature is determined by logic based on the region of the determination criteria and the request rate. In other words, the region that meets the conditions is determined in step S22, and the above calculated demand rate is plotted on the criterion of FIG. 7B. If the plotted position is in the range of □, the current target temperature To In the case of ▽, the temperature that is lower than the current target temperature To by a predetermined value (for example, Δt = 0.5 ° C.) is set as a new target temperature To. (Set temperature) A temperature that is a predetermined value (for example, Δt = 0.5 ° C.) higher than To is set as a new target temperature To (steps S23 to S25). The target temperature To is determined by this plot (step S26).

  When the target temperature To is determined, a process for setting the determined target temperature To in the air conditioning control device 2 is performed. That is, when the new target temperature To (target temperature To = target temperature To ± Δt) is obtained from FIG. 7B as described above (step S5), the obtained target temperature To is further determined as the lower limit value and the upper limit value of the control range. It is checked whether it is between the values (step S6).

  If it is within the range in this check, the target temperature To is determined as a new target temperature To. On the other hand, if the upper limit value is exceeded or falls below the lower limit value, the upper limit value or the lower limit value is determined as the target temperature To (step S7).

  After the determination of the target temperature To (step S8), the control plan drafting unit 45 updates the feedback information for displaying the control content of the air conditioning by the input device 3 (step S9), and thereafter the determined target temperature To Is sent to the air conditioning control device 2 to perform a process of setting a new target temperature To in the air conditioning control device 2 (step S10). After this processing, the process returns to step S1 until the system operation is stopped. The above operation is repeated. The air conditioning control device 2 includes a room temperature sensor 2a that measures the temperature in the space A, and the air conditioning equipment device 1 is adjusted so that the temperature measurement data measured by the room temperature sensor 2a matches the determined target temperature To. Control. Note that the feedback information generated in step S9 is delivered to the input device 3 in response to a request from the input device 3, and the user can check the control content of the air conditioning displayed on the input device 3.

  In this way, each user's desired strength is normalized in consideration of each user's personality and tendency, and the target temperature To is determined based on this normalized desired strength. Accordingly, air-conditioning control based on the user's agreement can be performed.

(Embodiment 2)
The configuration of the air conditioning control system of the present embodiment is the same as that of the first embodiment, and the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 8 shows a monitor screen after the input device 3 is activated. The user of the input device 3 inputs environmental information Inf indicating the current thermal environment, and is “very hot” or “hot”. ”,“ Slightly hot ”,“ Slightly cold ”,“ Cold ”,“ Very cold ”, and a screen for selecting and inputting the feeling of cold, respectively, and check boxes C11 to C16 corresponding to the corresponding cold feeling When the user clicks the send button B2 and checks the environment information Inf indicating the current thermal environment, the server device 4 together with its own identification information and air conditioning number is displayed. Uploaded to

  Then, when the environment information Inf is collected from each input device 3 in the server device 4, the request information acquisition unit 41 determines that each user's request for temperature is “increase temperature” from the feeling of coldness in the environment information Inf. Or "I want you to lower the temperature". Specifically, if it is “very hot”, “hot”, “somewhat hot”, it is determined that “I want to lower the temperature”, the request information Inf1 is set to “+1”, “somewhat cold”, “ If it is “cold” or “very cold”, it is determined that “I want to raise the temperature”, and the request information Inf1 is set to “−1”.

  Further, the requested strength acquisition means 42 sets the desired strength (requested strength) Inf2 for each user's temperature to any point P of “1”, “2”, and “3” based on the feeling of coldness in the environmental information Inf. Classify. Specifically, if it is “slightly hot” or “slightly cold”, point P is set to “1”, and if it is “hot” or “cold”, point P is set to “2” and “very hot”. If it is “very cold”, the point P is set to “3”. The request information Inf1 and the desired strength Inf2 of each user are sequentially stored in the history storage means 46.

  Subsequent normalization processing of the desired strength Inf2, determination processing of the target temperature To, and the like are the same as those in the first embodiment, and a description thereof will be omitted.

(Embodiment 3)
The configuration of the air conditioning control system of the present embodiment is the same as that of the first embodiment, and the same components are denoted by the same reference numerals and description thereof is omitted.

  In the history storage means 46 of the server device 4 of the present embodiment, the target illuminance To when each user's desired information Inf1 and desired intensity Inf2 are acquired is stored corresponding to each data.

  Then, when normalizing the desired intensity Inf2, the normalizing means 43 extracts the past desired intensity Inf2 acquired when the target temperature To is the same as the current target temperature To, and based on the extracted history Normalization process. In this normalization process, the weighting factor W is calculated according to the above [Equation 1] from the appearance frequency F of the desired intensity Inf2 for each user (for each identification information) when the target temperature To is the same as the current target temperature To. To derive. Then, the normalizing means 43 multiplies the desired strength Inf2 input by each user by the weighting factor W to calculate the weighted desired strength Inf2 '.

  For example, FIG. 9A shows a history of appearance frequency F with respect to a user's desired intensity Inf2 (point P) when the target temperatures To = 26 ° C. and 28 ° C. From the above [Equation 1]. The weighting factor W11 = 0.71 when the target temperature To = 26 ° C., the weighting factor W12 = 0.40 when the target temperature To = 28 ° C., and the target temperature To is the horizontal axis and the weighting factor W is the vertical axis. When plotted on the graph, it becomes as shown in FIG. 9B, and this characteristic is approximated to a straight line in which the weighting factor W decreases as the target temperature To increases, as shown by the straight line L1 in FIG. 9B.

  Each user's desired strength Inf2 is affected by the temperature level in the space A, and as described above, the past desired strength Inf2 obtained when the target temperature To is the same as the current target temperature To. Based on the normalization of the desired intensity Inf2 for each user, the air conditioning control based on the user's agreement can be performed according to the temperature level in the space A.

  In the second embodiment as well, the above effect can be obtained by performing normalization of the desired strength for each user in the same manner.

(Embodiment 4)
As shown in FIG. 10, the configuration of the air conditioning control system of the present embodiment is provided with an outside air temperature sensor 47 and outputs data of the outside air temperature Tg measured to the server device 4, and history storage means 46 of the server device 4. Stores the ambient temperature when each user's desired information Inf1 and desired intensity Inf2 are acquired corresponding to each data.

  Then, the normalizing means 43 extracts the past desired intensity Inf2 acquired when the outside air temperature Tg is the same as the current outside air temperature Tg, and calculates the requested intensity Inf2 for each user based on the extracted history. Normalize to In this normalization process, the weighting factor W is calculated according to the above [Equation 1] from the appearance frequency F of the desired intensity Inf2 for each user (for each identification information) when the outside temperature Tg is the same as the current outside temperature Tg. To derive. Then, the normalizing means 43 multiplies the desired strength Inf2 input by each user by the weighting factor W to calculate the weighted desired strength Inf2 '.

  For example, FIG. 11A shows an appearance frequency F for a user's desired intensity Inf2 (point P) at the hottest day (outside temperature Tg = 33 ° C.) and autumn (outside temperature Tg = 22 ° C.). From the above [Equation 1], the weight coefficient W21 = 0.40 for the hottest day and the weight coefficient W22 = 0.71 for the autumn season are shown. The date and time are plotted on the horizontal axis, the weight coefficient W and the outside temperature Tg are plotted vertically. When plotted on a graph along the axis (□: weighting factor W, ■: outside air temperature Tg), it becomes as shown in FIG. 11B, and the characteristic of the weighting factor W is approximated as a curve L2 in FIG. 11B. Is done.

  The desired intensity Inf2 input by each user is influenced by the outside air temperature Tg, and as described above, based on the history of the past desired intensity Inf2 acquired when the outside air temperature Tg is the same as the current outside air temperature Tg. Thus, by normalizing the desired intensity for each user, air conditioning control based on the user's agreement can be performed according to the outside air temperature Tg.

  In the second embodiment as well, the above effect can be obtained by performing normalization of the desired strength for each user in the same manner.

(Embodiment 5)
The configuration of the air conditioning control system of the present embodiment is the same as that of the first embodiment, and the same components are denoted by the same reference numerals and description thereof is omitted.

  The history storage means 46 of the server device 4 stores the history of the desired strength Inf2 of each user, and the normalizing means 43 performs the recent requested strength when normalizing the desired strength Inf2 for each user. The weight is increased as Inf2, and the normalization process similar to any one of the first to fourth embodiments is performed.

  The tendency of the desired strength Inf2 input by each user may change depending on the passage of the month and day. As in the present embodiment, the recent requested strength Inf2 is increased in weight, and the desired strength for each user is normalized. By performing the conversion, the air conditioning control based on the user's agreement can be performed according to the change in the personality and tendency of the user.

(Embodiment 6)
The configuration of the air conditioning control system of the present embodiment is the same as that of the first embodiment, and the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 12 shows a monitor screen after the input device 3 is activated, and the user of the input device 3 inputs environmental information Inf indicating the current thermal environment. This is a screen for selecting and inputting a request for a temperature "I want you to lower the temperature", and check the check fields C21 and C22 corresponding to the request for the corresponding temperature using a pointing device such as a mouse, By clicking the transmission button B3, the environment information Inf indicating the current thermal environment is uploaded to the server device 4 together with its own identification information and air conditioning number by the specific user at that time.

  When the environment information Inf is collected from each input device 3 in the server device 4, the request information acquisition unit 41 determines that the request for the temperature of each user is “I want to raise the temperature” from the environment information Inf. By determining which of “I want to lower the temperature”, the request information Inf1 is set to “+1” if “I want to raise the temperature”, and the request information Inf1 if “I want to lower the temperature” Is “−1”.

  Further, the requested strength acquisition means 42 counts the number of times the environmental information Inf having the same content is input within a certain time (the number of continuous inputs), and the requested strength to each user's temperature (by the number of counts) ( Desired strength) Inf2 is classified into one of points P of "1", "1.5", and "2". Specifically, the point P is set to “1” if it is input once (normal input) within a fixed time, and the point P is set to “1.5” if input is performed twice continuously within a fixed time. If the input is continuous three times or more within a certain time, the point P is set to “2”. The request information Inf1 and the desired strength Inf2 of each user are sequentially stored in the history storage means 46.

  Generally, the stronger the requested strength, the more the user tends to input environmental information Inf having the same content continuously. For example, FIG. 13A shows a history of certain environmental information Inf (“I want you to raise the temperature” or “I want you to lower the temperature”) input by a reluctant user, and FIG. Shows the history of certain environmental information Inf (“I want you to raise the temperature” or “I want you to lower the temperature”) entered by a user who has a strong self-assertion, normal input, continuous input twice, continuous input three times or more Each appearance frequency F is represented.

  Then, the normalizing means 43 normalizes the desired strength Inf2 for each user based on this history. In this normalization process, the weighting factor W is derived according to the above [Equation 1] from the history of the appearance frequency F for the desired strength Inf2 (point P) for each user (for each identification information) shown in FIG. For example, in the case of FIG. 13A, the weighting factor W31 = 0.87, and in the case of FIG. 13B, the weighting factor W32 = 0.56.

  Thus, since the desired intensity Inf2 is obtained by counting the number of continuous inputs of the same environmental information Inf, the environmental information Inf can be composed of only the desired information Inf1, and the simplified environmental information Inf can be used.

  Subsequent normalization processing of the desired strength Inf2, determination processing of the target temperature To, and the like are the same as in any of the first to fifth embodiments, and a description thereof will be omitted.
