Description

  The present invention relates to an air conditioning control system.

  In recent years, social demands for energy conservation due to global warming are increasing. 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).
JP 2004-205202 A

  As in the above-mentioned Patent Document 1, in a system that sets a target temperature based on a user's request, a request information rate for increasing energy consumption (a request to “lower the temperature” during cooling, If the request “I want you to increase” is higher than the first reference value, change the target temperature in the direction to increase energy consumption, and the rate of request information to reduce energy consumption (“I want you to raise the temperature during cooling”) If the request, “request to lower the temperature” during heating, is greater than or equal to the second reference value, control is performed to change the target temperature in a direction to reduce energy consumption. The reference value was fixed at a constant value and could not be changed.

  However, among all users, if the number of people who declare one request is large and the number of people who declare the other request is small, minority users will find it difficult to report their requests due to circumstances such as withholding. There is a situation. For example, men and women generally feel different about temperature, and men are generally hotter and women are colder. Even in my office, where there are many men and few women, it is difficult to declare a request to “raise the temperature” with the majority of men.

  Further, 12 users of the majority group and 4 users of the minority group, the reference value for determining whether or not to adopt the request is a request rate of 20% [(12 + 4) × 0.2 = 3.2≈ In the case of “4 people”, the majority user is adopted if there is a request of 4 out of 12 people, and the minority user is not adopted unless there is a request of all 4 people.

  In such a case, minority users will not be hired even if they declare their requests, and the situation will be that they do not declare that the majority users' requests will be adopted, The demands of the minority become increasingly difficult to realize, while the demands of the majority users become more and more likely to be realized.

  Therefore, there has been a demand for an air-conditioning control system that can realize the demands of majority users and minority users in the same way.

  This invention is made | formed in view of the said reason, The objective is to provide the air conditioning control system which can implement | achieve the request of a minority user similarly to the request of a majority user.

  According to the first aspect of the present invention, there is provided an air conditioning equipment that varies the temperature of a space to be air-conditioned, an air conditioning controller that controls the operation of the air conditioning equipment based on the target temperature, and a central control that sets a target temperature in the air conditioning controller. A device and an input device for inputting two conflicting requests for the temperature of the space from a user existing in the space, and the central control device obtains two conflicting requests of the user from the input device. By changing the target temperature in one direction by comparing the acquisition means, the rate of one desired information and the first reference value, and comparing the rate of the other desired information and the second reference value Control plan drafting means for changing the target temperature in the other direction and a reference value setting stage for setting the first and second reference values in a variable manner are provided.

  According to the present invention, by setting a target temperature based on a user's request and maintaining comfort while setting each of the first and second reference values so as to be variable, the request of a minority user Can be realized in the same way as a majority user request.

  The invention of claim 2 comprises personal attribute storage means for storing personal attribute information of all users according to claim 1, wherein the reference value setting means corresponds to the ratio of the same attribute in the personal attribute information of all users. Thus, the first and second reference values are set so as to be variable.

  According to the present invention, while setting the target temperature based on the user's request and maintaining comfort, the first and second reference values are set to be variable according to the ratio of the user's attributes. Thus, even if the way of feeling the temperature differs depending on the attribute, each request of the majority user and the minority user can be realized in the same way.

  According to a third aspect of the present invention, in the second aspect, the personal attribute information is gender, and the reference value setting means sets the first and second reference values according to the ratio of males and females of all users. It is characterized by setting each variable.

  According to the present invention, the ratio of the first and second reference values can be changed according to the ratio of male and female users while setting a target temperature based on the user's request and maintaining comfort. By setting each, even if the way of feeling the temperature differs depending on the gender, each request of the user having the majority gender and the user having the minority gender can be realized in the same way.

  A fourth aspect of the present invention is characterized in that, in the first aspect, the reference value setting means sets the first and second reference values in a variable manner according to a target temperature.

  According to this invention, while setting the target temperature based on the user's request and maintaining comfort, by setting each of the ratios of the first and second reference values to be variable according to the target temperature, Even if the user feels different about the temperature, the demands of majority users and minority users can be realized in the same way.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the control planning means increases the energy consumption by comparing the request information rate for increasing the energy consumption with the first reference value. The target temperature is changed, and the target temperature is changed in the direction of reducing the consumed energy by comparing the second reference value with the rate of the desired information for reducing the consumed energy.

  According to this invention, energy saving can be considered.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the first and second reference values are different from each other.

  According to the present invention, by applying different weights to the first and second reference values, it is possible to set the realization rate of each request of the minority user and the majority user to the same level.

  As described above, the present invention has an effect that the demands of the majority users and the minority users can be realized in the same way.

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

(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) On the air-conditioning equipment 1 and air-conditioning control device 2 installed in A, and on a communication network NT (Ethernet (registered trademark), etc.) in which each user in the space A inputs desired information Inf for the temperature of the space A A plurality of input devices 3 composed of personal personal computer terminals, and a central point connected to each input device 3 via a communication network NT and setting a target temperature To of space A based on the desired information Inf input by each user It is comprised by the control apparatus (henceforth a server apparatus) 4.

  The server device 4 collects the request information Inf from the input device 3 via the communication network NT and the request information Inf, and the request information Inf is totalized and registered in the database 42 of the total contents and determination criteria. Based on the determination criteria, a control plan drafting means 43 for deriving the target temperature To of the space A and passing it to the air conditioning control device 2 via the communication network NT, and a history memory for storing the history of the desired information Inf, the target temperature To, etc. Means 44, personal attribute information database 45 of each user, personal attribute storage means 46 for storing the current personal attribute information of all users extracted from personal attribute database 45, and personal attribute storage means 46 It comprises reference value setting means 47 for setting judgment criteria registered in the judgment criteria database 42 based on the personal attribute information of all users.

  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) composed of a refrigerator (cooling tower) or a 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. By obtaining from the server, the request information input means 31 is realized. 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 request information input means 31 is provided between the server device 4 and the input device 3. General browser software that realizes When each input device 3 inputs environmental information, the air-conditioning number of the target air-conditioning equipment device 1 (number specifying the air-conditioning area of the air-conditioning equipment device 1) and unique identification information (for example, an individual name or The e-mail address and the like are input, and the environment 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 ( Identification information) is sent, and necessary information such as a question format is acquired from the server apparatus 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.

  In the personal attribute database 45 of the server device 4, personal attribute information composed of the user's name, sex, age, and the like is registered in advance corresponding to each identification information (that is, each input device 3 is registered). When the personal attribute information of a specific user to be used is registered in advance, the server device 4 receives the identification information indicating the activation of the input device 3, and receives the personal attribute information corresponding to the identification information from the personal attribute database 45. Is extracted and stored in the personal attribute storage means 46. That is, the personal attribute storage means 46 stores personal attribute information of all users of the input device 3 that is currently activated.

  FIG. 3 shows a monitor screen after the input device 3 is activated. The user of the input device 3 inputs request information Inf indicating a request for the temperature of the current space A. This is a screen for selecting and inputting two conflicting requests for temperature, such as “I want you to reduce the temperature” and “I want you to lower the temperature”, and check the C1 and C2 corresponding to the corresponding request with a pointing device such as a mouse. By using and checking and clicking the transmission button B1, the request information Inf of the specific user at that time is uploaded to the server device 4 together with the identification information and the air conditioning number. Further, the screen for inputting the request 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.

  The request information acquisition means 41 collects the request information Inf transmitted to the server device 4 side using the browser software installed in each input device 3 used by the user, and records the request information Inf as a history. A process of writing in the storage unit 44 is performed. About the request information Inf transmitted from the user input device 3 through the communication network NT, from which identification information of the input device 3 is transmitted, which user transmitted what time and in what position in the space A, The request information Inf is specified based on the personal attribute information stored in the personal attribute database 45 in association with the identification information or the arrangement information of the input device 3 stored in the external storage device. And the identification information and the air conditioning information are stored in the history storage unit 44 in association with each other.

  For the request information Inf collected from the input device 3 in this way, the control plan drafting means 43 of the server device 4 is stored in the database 42 and the request information Inf stored in the history storage means 44. And calculate the ratio (request rate) to the total number of users of the two conflicting demand information such as “I want you to raise the temperature” and “I want you to lower the temperature”. The target temperature To is determined by the consensus building logic that compares the ratio with the criterion rule. Here, the air-conditioning equipment 1 is cooling the space A, and the request to “increase the temperature” is request information to reduce the energy consumption, and the request to “decrease the temperature” increases the energy consumption. It is request information to be made. The total number of users is determined by the number of personal attribute information stored in the personal attribute storage means 46.

  As shown in FIG. 4, the determination criteria rule stored in the database 42 is a request rate that “the temperature is desired to be increased” on the vertical axis and a request rate that “the temperature is desired to be decreased” on the horizontal axis. Take the line connecting both points with a request rate of 100% and the line that connects the zero point from the point where 65% wants to raise the temperature and 35% wants the temperature to fall. The area surrounded by the vertical axis of 0% is designated as the target temperature rise area “▲”, the line connecting both points with the desired rate of 100%, “I want to raise the temperature” is 35%, “Temperature The area surrounded by the line connecting the 65% point to the 0 point and the "Want to increase the temperature" line with the 0% horizontal axis is the target temperature drop region "▼". A region sandwiched between the rising region “▲” and the target temperature decreasing region “▼” is set as the target temperature maintaining region “■”. However, if the number of declarations is small, it is assumed that the user is not dissatisfied with the environment, and the request rate of “I want to lower the temperature” is less than or equal to the first reference value K1 with respect to the total number of users. The area where the request rate is less than or equal to the second reference value K2 is also set as the target temperature maintenance area “■”. In this determination reference rule, the first reference value K1 and the second reference value K2 are set by the reference value setting means 47 so as to be variable.

  The control plan drafting unit 43 performs consensus building processing based on the above-mentioned determination criterion rule, and specifically performs processing according to the flowchart of FIG. First, the request information acquisition unit 41 sequentially stores the request information Inf from each input device 3 in the history storage unit 44 (step S1).

  Next, the reference value setting means 47 pays attention to the gender attribute of the personal attribute information of all users stored in the personal attribute storage means 46, and calculates the ratio of males and females of all users ( In step S2), the first reference value K1 and the second reference value K2 of the determination reference rule of FIG. 4 are set in proportion to the ratio of male to female (step S3). Specifically, when there are 12 male users and 4 female users, K1: K2 is 12: 4. For example, the first reference value K1 = 37% (out of the total 16 users, 6), the second reference value K2 = 12% (corresponding to requests from 2 out of 16 users). In this way, by setting the ratio of the first reference value K1 and the second reference value K2 in proportion to the ratio between men and women, the majority of men who generally tend to get hot are men 12 The target temperature To can be lowered by a request from 6 of the people who want to lower the temperature, and in general, a minority of women who tend to get cold, The target temperature To can be lowered by the request of “I want to lower it”, and the demand of minority women is also the same as the demand of men of the majority. Therefore, a minority woman thinks that she may be hired if she declares her request, and by declaring her request, each request of the majority user and minority user is the same. It becomes feasible.

  When the reference value setting unit 47 sets the first reference value K1 and the second reference value K2, a configuration in which both the first reference value K1 and the second reference value K2 are changed, or the second reference value K2 is set. Either a configuration in which only the first reference value K1 is changed without changing the reference value K2 or a configuration in which only the second reference value K2 is changed without changing the first reference value K1 may be used.

  Then, the control plan drafting means 43 extracts the latest request information Inf for each user from the history storage means 44 and makes it valid data (step S4), and calculates the demand rate from the valid data of these demand information Inf. Then, the target temperature To is determined by the consensus building logic based on the determination criterion rule area and the request rate of FIG. 4 (step S5). That is, the above-calculated desired rate is plotted in the determination criterion rule of FIG. 4, and the current target temperature To is maintained when the plotted position is in the range of ■, and in the case of ▼, the current target temperature To A temperature lower than To by a predetermined value (for example, Δt = 0.5 ° C.) is set as a new target temperature To, and if within the range of ▲, it is increased from the current target temperature To by a predetermined value (for example, Δt = 0.5 ° C.). The new temperature is set as a new target temperature To (step S6).

  Next, it is checked whether or not the target temperature To is between the lower limit value and the upper limit value of the control range (step S7). If the target temperature To is within the range in this check, the target temperature To is set as a new target temperature To. decide. 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 S8).

  After the determination of the target temperature To (step S9), the control plan drafting means 43 updates the feedback information for displaying the control content of the air conditioning by the input device 3 (step S10), and thereafter the determined target temperature To Is stored in the history storage means 44 and transmitted to the air conditioning control device 2 to set a new target temperature To in the air conditioning control device 2 (step S11). After this processing, the process returns to step S1 and thereafter The above operation is repeated until the system operation is stopped.

  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 S <b> 10 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.

  As described above, the first and second reference values K1 and K2 used for the consensus building logic are set as the user attributes while maintaining the comfort by setting the target temperature To based on the user's request by the consensus building logic. By setting each to be variable according to the ratio, even if the way of feeling the temperature differs depending on the attribute, it will not be difficult to adopt the request of users with minority attributes, and with the majority users Each request of minority users can be realized in the same way. When the ratio of males and females of all users varies, the first and second reference values K1 and K2 also vary and are always set appropriately.

(Embodiment 2)
FIG. 6 includes the air conditioning equipment 1 and the air conditioning control device 2 installed in the space A, a plurality of input devices 3, and the server device 4 as in the first embodiment. The server device 4 obtains desired information. Means 41, judgment criterion database 42, control plan drafting means 43, history storage means 44, and reference value setting means 48 for setting judgment criteria registered in judgment criterion database 42 based on target temperature To. With. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and description is abbreviate | omitted.

  The reference value setting means 48 of the present embodiment can change the ratio of the first and second reference values K1 and K2 of the determination reference rule of FIG. 4 based on the target temperature To determined by the control planning means 43. Set. Specifically, considering the protection of women from over-cooling and energy saving during cooling, the first reference value K1 should be equal to or less than 27 ° C. as shown in FIG. 7A. If the set temperature To is 27 ° C. or higher, it is a value on a straight line or curve that decreases from the upper limit value. Therefore, when the target temperature To is 27 ° C. or less, it is difficult to adopt the request “I want to lower the temperature”, and it becomes possible to protect women and save energy from being too cold.

  Also, when considering only the protection of women from being too cold during cooling, the first reference value K1 is an upper limit if the current target temperature To is 24 ° C. or lower, as shown in FIG. 7B. If the set temperature To is 24 ° C. or higher, the value is on a straight line or curve that decreases from the upper limit value. Therefore, when the target temperature To is 24 ° C. or lower, it is difficult to adopt the request “I want you to lower the temperature”, and it is possible to protect women from being too cold.

  Note that the upper limit value (1% to 100%) in FIG. 7 and the target temperature To starting to decrease from the upper limit value can be arbitrarily set according to the characteristics of the system.

  In this way, the first and second reference values K1 and K2 used for the consensus building logic are set according to the target temperature To while maintaining the comfort by setting the target temperature To based on the user's request by the consensus building logic. If the target temperature To is less than a certain temperature, the majority of men's desires to “lower the temperature” will be difficult to be adopted. Even if they are different, it does not become difficult for women with minority attributes to request “raise the temperature” and the demands of majority users and minority users are the same. It becomes feasible.

  In consideration of energy saving during heating, the second reference value K2 is an upper limit if the current target temperature To is 20 ° C. or higher, as shown in FIG. 7C, and the set temperature To is 20 ° C. If it is below, it becomes a value on a straight line or a curve decreasing from the upper limit value. Therefore, when the target temperature To is 20 ° C. or higher, it is difficult to adopt the request of “I want to raise the temperature”, and energy saving becomes possible.

  In addition, in the said embodiment, although mainly illustrating about the case where the air conditioning equipment 1 is cooling the space A, when the air conditioning equipment 1 heats the space A, "I want you to raise temperature." The request becomes request information for increasing the energy consumption, and the request “I want to lower the temperature” becomes the request information for reducing the energy consumption, and can be processed in the same manner as during cooling.
