Description

  The present invention relates to an environment control system that controls the environment (temperature, lighting, etc.) of a target space while balancing the user's demand and power consumption.

  In recent years, air conditioning equipment that accounts for a large amount of energy consumption in buildings such as office buildings has been adopted from a centralized heat source system to an electric individual distributed type (multi-type air conditioning system) in order to improve technology and facilitate maintenance. Buildings are increasing. With the increasing adoption of such multi-type air conditioning systems, energy consumption forms tend to concentrate on electricity. For this reason, it is important to appropriately control the amount of demand power in order to reduce the energy cost.

  On the other hand, the temperature control of the living space where energy saving and comfort are intricately related is the most important point for energy management, but it cannot be said that it is properly managed. For example, a building manager of an office building does not necessarily operate air conditioning equipment such as cooling and heating appropriately from the viewpoint of comfort and energy saving, but sets a customary target temperature for ease of management, In general, the setting value is changed by a complaint from a user who enjoys the temperature environment. In other words, because temperature management is performed without fully considering the characteristics of the building or occupants, the living space is not necessarily maintained in a comfortable state for the user, and further, energy consumed by the air conditioner is generated. There is. In addition, some users are dissatisfied with the fact that they are in a temperature environment managed by the building manager and cannot control their own temperature environment.

In response to the problems caused by temperature management of air conditioning control, requests for users' temperature environment are collected in real time from personal computer terminals (hereinafter referred to as personal computers) operated by each individual, and There is an environment (air conditioning) control system that sets the target temperature based on it, and the user's desired temperature environment and target temperature are correlated in real time, and the user characteristics that change from moment to moment and the actual temperature and detection of the living space The temperature environment can be changed in accordance with the characteristics of each building such as the difference from the temperature (see, for example, Patent Document 1).

  By the way, demand control determines the target demand amount for the day before environmental control equipment such as air conditioners and lighting equipment starts operation, and power according to priority so that the maximum demand power does not exceed the target power. Consuming equipment (air conditioning equipment and lighting equipment) is sequentially subjected to capacity control and start / stop control every predetermined time. If the actual power consumption exceeds the specified reference value, an additional fee will be charged by the power company, or the power contracted with the power company (contract power) will have to be increased. It must be ensured that power consumption does not exceed contract power through control. In particular, air-conditioning equipment and lighting equipment are often controlled by demand control due to their relatively long usage time. And it is possible to adjust the power consumption so that it does not exceed the contract power by temporarily relaxing the environmental conditions of temperature and lighting and suppressing the power consumption of air conditioning equipment and lighting equipment. Content.

  However, for example, because the conditions of the external environment such as sunlight are different between the lower floors and the higher floors of an office building, if the temperature environment and lighting environment of all floors (floors) are aligned to the same conditions, The satisfaction that users feel about the temperature environment and lighting environment is of course different, and there are floors where users do not feel any dissatisfaction with the relaxation of environmental conditions through demand control. Is also present.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an environment control system capable of improving the comfort of the entire plurality of target spaces while saving energy by demand control.

  In order to achieve the above object, the invention of claim 1 includes one to a plurality of types of environmental adjustment devices for preparing the environment of a plurality of target spaces in which a user exists, and a plurality of environmental adjustment devices for each type. One or more types of environmental control devices that individually control the operating state and the amount of power consumed by the environmental adjustment device to prepare the environment are monitored, and the total amount of power consumed in all target spaces is a predetermined value. A demand control device that controls an environmental adjustment device to reduce power consumption for at least one of the environmental control devices when it is predicted to exceed, and a target that is input by a user existing in the target space A demand control device comprising: an input device for receiving request information for a space environment; and an analysis device for analyzing the request information received by the input device for each target space and obtaining a degree of request for a change in the environment. Apportions the total amount of power allowed in the entire system according to the degree acquired from the analysis device, and controls each environment so as not to exceed the allowable power amount for each target space determined from the apportionment result. The apparatus is characterized by controlling an environmental adjustment device.

  According to the first aspect of the present invention, the demand control device apportions the total power amount allowed in the entire system according to the degree acquired from the analysis device, and for each target space determined from the apportionment result. Because each environmental control device controls the environmental adjustment equipment so that the allowable power amount of the environment is not exceeded, a relatively large amount of power is apportioned in the target space where the degree of request for change is high, and the change is requested in the opposite direction. By apportioning a relatively small amount of power to the target space having a low degree, the overall comfort of the plurality of target spaces can be improved while energy consumption is reduced by suppressing power consumption.

  The invention of claim 2 comprises, in the invention of claim 1, an air conditioner that adjusts the temperature environment of the target space, and an illumination device that adjusts the illumination environment of the target space. The demand control device obtains the degree of request for change of the temperature environment and the degree of request for change of the lighting environment individually, and the demand control device determines the degree of the temperature environment and the lighting environment based on the analysis result obtained from the analysis device. The environmental control device that preferentially controls the relatively higher environment is preferentially controlled by the environmental control device.

  According to the invention of claim 2, the comfort can be further improved by preferentially changing the environment having a high degree of change request among the temperature environment and the lighting environment.

  According to a third aspect of the present invention, in the second aspect of the present invention, an opening for taking in light from the outside is provided in the target space, and the demand control device is a brightness detection unit that detects the external brightness. When the brightness detected by the brightness detection means is equal to or lower than a predetermined reference value, the illumination device is not selected as the environment adjustment device to be preferentially controlled by the environment control device.

  According to the third aspect of the present invention, when the amount of light taken in from the opening is small, the illumination environment of the target space cannot be adjusted without using an illumination device, so the external brightness detected by the brightness detection means is predetermined. When it is below the reference value, the light output of the lighting device can be adjusted to an appropriate state by not selecting the lighting device as the environmental adjustment device to be preferentially controlled by the environmental control device.

  According to the present invention, a relatively large amount of electric power is apportioned in a target space having a high degree of request for change, and a relatively small electric amount is apportioned in an object space having a low degree of request for change. As a whole, the comfort of the entire plurality of target spaces can be improved while saving energy by reducing the amount of power consumed.

  The following is an environmental control system that uses office rooms on each floor of an office building as the target space, adjusts the temperature environment in the office room with air conditioning equipment, and adjusts the lighting environment in the office room with lighting equipment (lighting fixtures). An embodiment to which the technical idea of the invention is applied will be described in detail with reference to the drawings.

  As shown in FIG. 1, the environmental control system of the present embodiment includes two types of environmental adjustment devices, an air conditioner 1 for adjusting the temperature environment and an illumination device 2 for adjusting the lighting environment, and the operating state of the air conditioner 1. Two types of environmental control devices, an air-conditioning control controller 3 for controlling the lighting and a lighting control controller 4 for controlling the operating state of the lighting device 2, and input of user's temperature and lighting requirements in the target space (office) An input device 5 to receive, an analysis device 6 that analyzes request information provided from the input device 5, and a demand control device 7 that controls the demand of the environmental adjustment device based on the analysis result of the analysis device 6 are provided. In FIG. 1, only one set each of the environmental adjustment device, the environmental control device, and the analysis device 6 is shown. However, the environmental adjustment device, the environmental control device, and the analysis device 6 are provided for each office on each floor. Each demand control device 7 installed in a place other than the office is connected by a communication line.

  The air conditioner 1 is a multi-type unit composed of a plurality of indoor units 1a installed in the office room and an outdoor unit 1b that is a heat supply unit that supplies a heat medium to each indoor unit 1a, such as a heat exchanger and a heat source device. Is. The air conditioning controller 3 controls each indoor unit 1a and outdoor unit 1b so that the temperature of the temperature sensor 1c installed in the office room, that is, the temperature of the office room becomes the target temperature.

  The lighting device 2 is composed of a plurality of high-frequency lighting dedicated fluorescent lamp luminaires installed on the ceiling in the office. The illumination controller 4 performs dimming control on the illumination device 2 so that the illuminance detected by the illuminance sensor 2a installed on the ceiling becomes the target illuminance.

  FIG. 2 shows an installation example of the present embodiment. As shown in the figure, the offices of the floors F1 to F4 from the first floor to the fourth floor of the office building are set as target spaces, and a plurality of ceilings in each office room are provided. An indoor unit 1a is installed, and an indoor unit 1a on the same floor is connected to an outdoor unit 1b provided for each floor so that a heat medium is supplied. Similarly, a plurality of lighting devices 2 are installed on the ceiling in each office. An air conditioning controller 3 and a lighting controller 4 are also provided for each floor. The indoor unit 1a and the outdoor unit 1b on the same floor are connected to the air conditioning controller 3 by signal lines. Lighting devices 2 on the same floor are connected by signal lines. In other words, the air conditioning controller 3 and the lighting controller 4 control the operation state of each device by the control signal transmitted to the indoor unit 1a, the outdoor unit 1b, and the lighting device 2 through the signal lines.

  The input device 5 is realized by accessing a web server installed in the analysis device 6 by a web browser installed in a personal computer used by each user. When accessing the web server of the analysis device 6, as shown in FIG. 3, a request for temperature, a request for brightness, a request for priority of temperature or brightness, and unique information for identifying the individual user A web page (hereinafter referred to as a “request declaration page”) for receiving input of the device numbers of the indoor unit 1a and the lighting device 2 to be requested for temperature and brightness (name in the illustrated example). The information that is displayed on the screen 5 (computer monitor screen) and is input by the user by operating a pointing device such as a keyboard or a mouse is transferred from the input device 5 to the analysis device 6 by a computer network (local area network). <LAN>). Also, in this embodiment, there are two types of requests for temperature: “I want you to raise the temperature” and “I want you to lower the temperature”, and “I want you to make it brighter” and “I want you to make it darker” Two types of information can be entered. The name, air conditioning equipment number, and lighting equipment number information are cached for each input device 5 and are automatically entered when the request report page shown in FIG. 3 is displayed on the screen.

  The analysis device 6 functions as a web server, and as described above, the user's report received by the input device 5 through the request report page (request for temperature and brightness, user's name, target environmental adjustment device) Device information) via the LAN, and the request information from each input device 5 acquired by the report information acquisition unit 60 is analyzed for each type of temperature and brightness, and the environment (temperature and brightness) is analyzed. And a dissatisfaction determining unit 61 that determines the target temperature of the air conditioner 1 and the target illuminance of the lighting device 2 by the consensus building logic described later. The report information acquisition unit 60 and the dissatisfaction determination unit 61 are realized by causing a microcomputer to execute a dedicated program.

  Here, in the dissatisfaction determining unit 61, the consensus building logic for determining the target temperature to be instructed to the air conditioning controller 32 and the target illuminance to be instructed to the illumination controller 4 according to the user's request will be described. However, since the consensus building logic is already known as described in Patent Document 1, only the procedure for setting the target temperature will be described below.

  First, when users A, B, C, and D arbitrarily report a temperature-related request using the input device 5 at the timing indicated by □ in FIG. 4, the reporting information acquired by the reporting information acquisition unit 60 in the analysis device 6 ( (Request information regarding temperature) is written in a report information file of a storage device (not shown). The report information acquired and written in the report information file is retained for a predetermined time (for example, 1 hour) from the time of the report, and is reset after the predetermined time has passed and becomes a non-report state. Further, the uppermost row in FIG. 4 shows the transition of the temperature (room temperature in the office), and the user's declaration is not accepted in the process ta where the temperature changes with the change of the target temperature.

  As shown in FIG. 5, if the reporting information is transmitted from the input device 5 at the time shown in FIG. 5 where the total number of users is 4 to A, the contents of these reporting information are “ "1" for "I want you", "0" for "Neither", and "-1" for "I want you to lower the temperature" Is written in the report information file.

  In this illustrated example, user A makes a declaration at times 9:58 and 11:00, but the reporting information in the 9:58 declaration is reset at 10:58 after one hour has passed.

  The dissatisfaction determining unit 61 performs the following processing in order to use such report information for determining the equipment control content (target temperature change plan). That is, if there is no change in the content of the declaration as shown in FIG. 5B, the information in FIG. 5 (a) is changed to the content of the declaration every minute after the user's declaration or It is handled until it is reset, and after it is reset, it is converted to information to be in a non-declared state until a new declaration is made and written to the analysis file.

  Using the analysis information in FIG. 5B, the dissatisfaction determining unit 61 calculates a request rate for the total number of users of conflicting reporting information “I want to raise the temperature” and “I want to lower the temperature”, and Processing for obtaining the ratio of the request rate (the degree of request for change) is performed. That is, in FIG. 5B, the request rate obtained from the analysis information at time 10:59 is 50% for “I want to raise the temperature”, 25% for “I want to lower the temperature”, and 11:00 , The required rate of “I want to raise the temperature” is 75%, and the required rate of “I want to lower the temperature” is 25%.

  In this way, the dissatisfaction determining unit 61 obtains the contradictory reporting information request rate and its ratio with respect to the total number of users based on the information converted for analysis from the reporting information reported every minute. Based on this ratio, the target temperature change plan is determined (target temperature setting) as will be described later.

  The target temperature change plan determination process is executed based on the following consensus logic. As shown in FIG. 6, the dissatisfaction determining unit 61 sets the request rate of the request of “I want to lower the temperature” as the x axis and the request rate of the request of “I want you to increase the temperature” as the y axis. An area Sn (n = 1, 2, 3) for determination criteria is provided in the two-dimensional orthogonal coordinate system, and an area Sn that meets the conditions is determined by plotting points with the two desired rates as x-coordinate and y-coordinate respectively. To do. Roughly, in the region where the ratio of the y-axis request rate is high with respect to the x-axis request rate, the target temperature is changed to increase, and the region where the ratio of the x-axis request rate is high with respect to the y-axis request rate Then, the target temperature is changed so as to decrease, and the target temperature is not changed in the region where the ratio of the two types of request rates is close to 1.

  That is, as shown in FIG. 6, a straight line B connecting the points of the x-axis and y-axis request rates of 100%, the origin and the x-axis request rate of 35%, and the y-axis request rates of 65% are connected. The straight line b, the straight line with a y-axis request rate of 10%, and the area surrounded by the y-axis are S1, and the origin and the x-axis request rate are 65% and the y-axis request rate is 35%. The straight line d, straight line b, straight line c, straight line ho with an x-axis desired rate of 10%, and the area surrounded by the x-axis and y-axis are defined as S2, and are surrounded by straight lines b, d, e, and x-axis. This area is S3. The dissatisfaction judging unit 61 plots points having two kinds of request rates as x-coordinate and y-coordinate, respectively, and if the plotted points belong to the region S1, the temperature is raised by a predetermined change width ΔT from the current target temperature. If the plotted point belongs to the region S3, the temperature is lowered from the current target temperature by a predetermined change width ΔT, and if the plotted point belongs to the region S2, the current target temperature is not changed. The content of the agreement with respect to the user's request existing on each floor F1 to F4 is determined. Further, the dissatisfaction judging unit 61 determines the agreed content, that is, the request regarding the temperature “I want you to raise the temperature” or “I want you to lower the temperature”, and “I want you to make the lighting brighter” or “Make the light darker” The request rate and the number of requests regarding lighting “I want” are transmitted to the demand control device 7 as dissatisfaction information for each floor F1 to F4.

  The demand control device 7 includes an entire building dissatisfaction information collecting unit 70, an electric energy apportioning processing unit 71, an operable target setting calculating unit 72, an electric energy measuring unit 73, and a demand controlling unit 74. The entire building dissatisfaction information collection unit 70 periodically collects dissatisfaction information from the analysis devices 6 installed on the floors F1 to F4, and totals the dissatisfaction state of the entire building. The electric energy apportioning processing unit 71 apportions the total electric energy allowed in the entire building (the entire system) according to the dissatisfied state of the entire building collected and totaled by the entire building dissatisfaction information collecting unit 70. The operable target setting calculation unit 72 is a target temperature (cooling) that can be set in the air conditioner 1 of each floor F1 to F4 within a range that does not exceed the amount of power for each floor F1 to F4 apportioned by the electric energy apportioning processing unit 71. And the target illuminance (maximum illuminance) that can be set in the lighting device 2 is calculated. The power amount measurement unit 73 measures the amount of power consumed by the present system in the entire building (mainly the amount of power consumed by the air conditioner 1 and the lighting device 2).

  As shown in FIG. 7, the demand control unit 74 sets two types of high and low warning areas X1 and X2 for the daily target power amount (target demand amount) Ws based on the contract with the power company. When it is predicted that the amount of power used per minute (the amount of power measured by the power amount measuring unit 73) will reach a preset warning area X1 or X2, the target temperature and lighting control set for the air conditioning controller 3 Peak cutting is performed by changing the target illuminance set for the controller 4 (demand control) to prevent the contracted power (target power amount Ws) from being exceeded. If the power amount suddenly increases and exceeds the target power Ws, the demand control unit 74 follows the priorities registered in advance, and the priority is low until the power amount falls below the target power amount Ws. The air conditioning controller 3 or the lighting controller 4 is instructed to stop in order from the device. For example, 90% to 95% of the target power Ws is set as the lower warning area X2, and 95% to 100% of the target power Ws is set as the higher warning area X1. That's fine. Further, when the demand control unit 74 predicts the amount of power used (demand amount), the prediction accuracy can be improved by using a known technique such as a neural network or multiple regression analysis.

  Next, the operation of this embodiment will be described with reference to the flowchart of FIG. In the analysis devices 6 installed on the floors F1 to F4, request information arbitrarily reported from the input device 5 is collected by the reporting information acquisition unit 60 (step s1), and the consensus building logic already described by the dissatisfaction determining unit 61 To extract the dissatisfaction information including the request rate of the request regarding temperature and lighting, the number of requests, and the number of users who declared each request (step s2). The dissatisfaction information for each floor F1 to F4 extracted by each analysis device 6 is totaled by the entire building dissatisfaction information collection unit 70 of the demand control device 7 (step s3). Further, the power amount apportioning processing unit 71 calculates the apportioning rate of the target power amount Ws according to the dissatisfaction information tabulated by the entire building dissatisfaction information collecting unit 70 (step s4), and each of the apportioning rate and the target power amount Ws. The available electric energy for each of the floors F1 to F4 is calculated (step s5).

  For example, when the request rate regarding the temperature and lighting of each floor F1-F4 is 8%, 10%, 15%, 15% as shown in FIG. 9, each floor F1-F4 with respect to the request rate of the whole building is shown. The degree of request rate can be calculated as: Request rate of each floor F1 to F4 / Total of request rates of all floors F1 to F4 × 100 [%], so 17%, 21%, 31%, 31%, respectively It becomes. Here, assuming that the target power amount Ws of the building is 150 kWh, the power amount usable for each floor F1 to F4 is 25.5 kWh, 31. 5 kWh, 46.5 kWh, and 46.5 kWh. In addition, instead of the degree of the request rate, the apportionment rate may be calculated based on the number of users who have reported, the number of reports, and the like.

  Subsequently, the operable target setting calculation unit 72 of the demand control device 7 calculates a target value of temperature and lighting (target temperature and target illuminance) from the available electric energy for each of the floors F1 to F4 (step s6). . As a specific calculation method, for example, setting conditions (target temperature and target illuminance range) of the air conditioner 1 and the lighting device 2 that can be set within a range of available electric energy are determined by simulation, and further, the setting is performed. What is necessary is just to calculate the change temperature for each floor F1-F4 from the average temperature which satisfies conditions, and wants to change in the whole building according to the degree of the request rate for each floor F1-F4. The target value (operable target setting value) calculated in this way is stored in the operable target setting file (step s7).

  On the other hand, in the demand control, the power consumption measuring unit 73 measures the power consumption (step s8), and the demand control unit 74 predicts the power consumption for 30 minutes (demand prediction) based on the measured value (step prediction). s9), it is determined whether or not the predicted value enters the alert area X1 or X2 (step s10). If the demand control unit 74 determines that the predicted value is below the lower alert area X2, it waits for the next step (next 30 minutes) without performing demand control (step s12). On the other hand, if it is determined that the predicted value falls within the lower alert area X2, the demand control unit 74 sets the target temperature set for the air conditioning controller 3 and the target illuminance set for the lighting controller 4 by a predetermined amount. The peak cut is performed by increasing / decreasing only (demand control), thereby preventing the contract power (target power amount Ws) from being exceeded. Further, when it is determined that the warning area X1 with the higher predicted value is entered, the demand control unit 74 reads out the target temperature and target illuminance stored in the operable target setting file, and the air conditioning controller 3 and the illumination controller 4 (Step s11). Here, the demand control unit 74 preferentially changes the target value of the target temperature and target illuminance, which has a relatively high degree of request rate, thereby improving user comfort. . However, if the outside light (mainly daylight) entering from the opening (window) of the office is small (at night, in the case of cloudy weather or rainy weather), the lighting of the target space (office) is not performed by the lighting device 2 Since the environment cannot be prepared, when the external brightness detected by the brightness detection means (illuminance sensor 2a) is equal to or lower than a predetermined reference value, the lighting device 2 is used as an environment adjustment device that is preferentially controlled by the environment control device. In this way, the light output of the lighting device 2 can be adjusted to an appropriate state.

  As described above, according to the present embodiment, the demand control device 7 apportions the total power amount allowed in the entire system according to the degree of the request rate acquired from the analysis device 6 and determines from the apportionment result. The environmental control devices (air conditioning devices 1 and 2) are connected to each environmental control device (air conditioning control controller 3 and lighting control controller 4) so as not to exceed the allowable power amount (operable target set value) for each target space. Since the control is performed, a relatively large amount of power is allocated to the target space where the degree of request for change is high, and on the contrary, a relatively small amount of power is allocated to the target space where the degree of request for change is low. As a whole, the comfort of the entire plurality of target spaces can be improved while saving energy by reducing power consumption.
