Description

  The present invention relates to a device operation evaluation information providing device, and more particularly to a device operation evaluation information providing device that provides operation evaluation information about a device that is installed in a building and consumes energy.

  In recent years, energy consumption countermeasures are demanded not only for the manufacturing industry itself but also for all energy users. According to the Law on the Rational Use of Energy (hereinafter referred to as the Energy Saving Law), in addition to the five industries such as the manufacturing industry, buildings and other buildings whose annual energy consumption such as heat and electricity exceeds the specified value are also designated as energy management. Has been amended. When designated as energy management, energy usage reporting and rationalization of use, so-called energy saving efforts are imposed.

  On the other hand, a building energy management system called BEMS (Building and Energy Management System) has been developed and put into practical use for building energy management. This BEMS is directed to a management system that automates and unifies the monitoring and control of equipment systems related to building energy consumption and the measurement of energy consumption during operation.

Building Energy Management Guide Energy Conservation Center

  By the way, there are various measures to perform energy saving measures, and it is conceivable to reduce the absolute energy consumption amount or to change the energy consuming device itself to a so-called energy saving device with a small energy consumption amount.

  Here, it is considered effective to consider energy consumption measures based on the operation status of the equipment. That is, the device is energy efficient when it is operating with its rated capacity. Therefore, the energy consumption can be reduced by analyzing the operation status of the device and designing or selecting the device so that it can be operated steadily with good energy efficiency.

  However, in the conventional design philosophy, when designing a new building, it is difficult to predict the operation status of the equipment, so that equipment with a relatively large rated capacity is installed, in other words, so that it can cope with various usages to some extent thereafter. And the equipment is installed in the over-spec trend. For example, in the case of an air conditioner, the requirements for operational equipment vary greatly depending on applications such as interpersonal or objective (server room air conditioning), number of rooms, etc. Therefore, even if a device with a large rated capacity is installed, if the capacity is not required in actual operation, it is considered that the operation is inefficient in energy efficiency.

  Therefore, it is possible to construct an energy saving measure by analyzing the operation of such equipment and changing to an appropriate equipment at the time of building renovation or renewal. Here, the operational analysis of this device is basically based on the energy consumption of the device. In the above-described BEMS, the energy consumption of the device is integrated, but the provision of only the energy consumption of this device does not provide an index as to whether or not the device is consistent with operational requirements. Therefore, it was not possible to analyze the operation of the equipment.

  Therefore, the present invention has been made in view of the first half problem, and provides an apparatus operation evaluation information providing apparatus that provides operation evaluation information as to whether or not the energy consumption of an apparatus is consistent with an operation requirement. For the purpose.

When the device group group is designated by the input device, the actual consumption acquisition unit acquires the actual energy consumption of the device having the attribute information of the device group group from the measurement data storage unit. standard consumption calculation unit is characterized that you calculate the standard energy consumption of the device having the attribute information of the device group set.

In the device operation evaluation information providing device of the present invention, the actual consumption acquisition unit determines the attribute information of the measurement data storage unit when the device group group is designated by the input device, and for each device. added to calculate the actual energy consumption, it characterized that you get the actual energy consumption of the device group group having the attribute information.

Further, in the device operation evaluation information providing device of the present invention, the quasi-consumption calculating unit determines the attribute information in the related information storage unit when the device group group is designated by the input device, and for each device. A standard energy consumption amount is calculated and added, and a standard energy consumption amount of a device group group having the attribute information is calculated .

Further, in the operation evaluation information providing device of the apparatus of the present invention, the attribute information of the device group set specified by the force device, at least Kaibetsu, system-based, or by application is included and wherein Rukoto.

  According to the present invention, since the operation evaluation information for evaluating the actual energy consumption is provided based on the standard energy consumption, it is possible to evaluate the operation of the device.

  Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

  First, the outline | summary of the apparatus operation evaluation information provision apparatus in this embodiment is demonstrated. The device operation evaluation information providing apparatus according to the present embodiment provides the actual energy consumption actually consumed by the device and the standard energy consumption consumed by the device as a standard, and based on these, the operation evaluation of the device is performed. Do. The actual energy consumption is the energy consumption actually consumed by the device. The standard energy consumption indicates the energy consumption estimated to be consumed by the device as a standard. It is the consumption estimated based on. By comparing the actual energy consumption with the standard energy consumption, it can be determined whether the device is consistent with the operational requirements. In this embodiment, it is possible to compare the actual energy consumption and the standard energy consumption for each predetermined group, for example, for each floor or each application, so that the total of devices belonging to a certain group can be compared. Operational evaluation is also possible.

  Next, a device operation evaluation information providing apparatus according to the present embodiment will be described. FIG. 1 is a configuration diagram illustrating a BEMS (Building and Energy Management System) including a device operation evaluation information providing apparatus according to the present embodiment. Here, BEMS is a system that manages equipment systems such as air-conditioning equipment that consumes energy installed in buildings and equipment that constitutes it, and includes a monitoring function, automatic control function, data measurement, measurement data analysis, It has a recording function, a communication function, and the like. In the present embodiment, the device operation evaluation information providing apparatus 10 collects measurement data from a sensor provided on the building 12 side and provides operation evaluation information via a relay device or the like connected via a network.

  In the building 12, an air conditioning facility, a hot water supply facility, and the like are installed as an energy consuming facility system 14, and the facility system 14 includes various devices 16. The device 16 includes a refrigerator, an air conditioner, an electric motor (used in a pump, an elevator, an escalator, etc.), a lighting fixture, and the like. These devices 16 are supplied with the energy required to fulfill their purpose. This energy is electricity or gas of gas fuel (city gas, LPG (liquefied petroleum gas), etc.), liquid fuel of kerosene, heavy oil, or the like. The building 12 is provided with a number of sensors 18 that measure the energy consumption of the equipment 16 when the equipment system 14 is operated. The sensor 18 is an integrating wattmeter, integrating calorimeter, or integrating flow meter, and is incorporated in the device 16 itself or attached to a predetermined location such as an electric room or a control panel that is a major source of energy supply. .

  FIG. 2 is a diagram illustrating an installation example of the integrating wattmeter. In FIG. 2, a power supply system is shown, and a plurality of integrated wattmeters 24 (indicated by WHM together with the management number in FIG. 2) are installed at predetermined locations. As shown in FIG. 2, the amount of power is measured at a plurality of locations such as upstream and downstream of the power supply system. Similarly, the amount of heat is measured at a predetermined location. Measurement data measured by the sensor 18 including the integrated wattmeter 24 is sent to the central monitoring device 20 as needed. For example, the recording device 22 reads and records the measurement data of the central monitoring device 20 once an hour.

  Next, the configuration of the device operation evaluation information providing apparatus 10 will be described.

  The apparatus operation evaluation information providing apparatus 10 includes a storage device 26 that records various data, a control device 28 that controls the entire device, an input device 30, and an output device 32.

  In the present embodiment, the storage device 26 stores a measurement data database 34 that stores measurement data for acquiring the actual energy consumption of the device, and energy consumption factor information for calculating the standard energy consumption of the device. Related information database 36.

  The measurement data database 34 reads measurement data from the recording device 22 and stores it. When there is a lot of measurement data to be read from the recording device 22, this storage operation is preferably performed, for example, at midnight. The measurement data is, for example, integrated data such as minutes, hours, days, months, and years. In the case where the sensor 18 is not an accumulator, in order to shorten the processing speed, the accumulated data may be stored in total for each predetermined unit of minutes, hours, days, months, and years. In addition, the measurement data is basically read from the recording device 22, but may be input separately by the input device 30 described later. The measurement data also stores attribute information such as measurement date / time and measurement time. When the units of measurement data are different, unit conversion may be performed using a predetermined conversion coefficient and stored.

  In the present embodiment, these measurement data are stored in association with the attribute information of a predetermined group so that the actual energy consumption can be calculated for each predetermined group. This attribute information is, for example, by floor, by system, by application, etc.

  The floor classification is an attribute for the installation floor of the device 16. For example, the attribute of belonging to the first floor, the second floor, every floor, or a plurality of floors 2 to 5 is added.

  By system is an energy type system of a power system and a calorie system. Further, in this system, for example, an attribute for each use can be attached according to the classification of the report document of the Energy Saving Law. In other words, the power system is air conditioning / ventilation (transport / water, transport / air, heat storage heater), hygiene (transport / water, hot water supply, middle water treatment), electricity (lighting / outlet), elevator (elevator, escalator), garbage It is roughly divided into transportation and kitchen equipment. Mechanical parking and disaster prevention are included in air conditioning / ventilation transportation / air. Conveyance / water classified as air conditioning / ventilation includes cold / hot water pumps. Conveyance / air includes air conditioners (personal and objective), air heat source heat pump, fan coil unit, steam generator, air conditioning ventilation fan, air Includes purifier and blower. Transportation / water classified as sanitary includes hot water pumps, chlorine infusion devices, pressurized water supply pumps, digestion circulation pumps, hot water circulation pumps, drainage pumps, auxiliary pressure pumps for fire extinguishing, and hot water supply classified as hygiene Includes an electric water heater and eco-hot, and middle water treatment includes a sewage pump, miscellaneous drainage pump, kitchen drainage pump, and blower. The trash transport includes a trash processing apparatus.

  By application, for example, attributes can be assigned according to application according to the category of report creation of the Energy Saving Law. For example, heat source, heat transfer, lighting / outlet, power, etc. are distinguished. Heat sources include air conditioner refrigerators, boilers, cooling towers, total heat exchangers, etc., heat transfer includes cold / hot water pumps, air conditioners, fan coil units, etc. Includes elevators, escalators, ventilation fans, etc. Others include experimental equipment and various losses.

  Moreover, if it is an air conditioner, a use can be classified according to a person or an objective.

  FIG. 3 is a diagram illustrating an example of the measurement data database 34 and explaining the measurement data 38 and the attribute information 40.

  FIG. 3A shows an example of storing measurement data of a heat source pump to which electric power is supplied from the B4 floor electric room. As shown in FIG. 3A, measurement data 38 is stored for each month. The measurement data 38 is stored in association with the attribute information 40 of the system such as the installation floor (in this example, no attribute is assigned), the low-rise middle-rise, and the high-rise for each heat source pump device 16.

  FIG. 3B shows an example of storage of measurement data 38 related to hot water calorific value. As shown in FIG. 3B, measurement data 38 is stored for each month. This measurement data 38 is stored in association with attribute information 40 for each application, such as installation floor, interpersonal or objective, for each air conditioner device 16.

  In this way, by attaching the attribute information, as described later, it is possible to acquire the actual energy consumption of a device group group composed of devices having the attribute. When it is desired to acquire the actual energy consumption of the first floor, the measurement data having the attributes of the first floor can be totaled to acquire the actual energy consumption of the first floor.

  In order to shorten the processing speed, the actual energy consumption of the device group group may be stored in advance. In this case, the actual energy consumption of the devices 16 belonging to the device group group may be summed to calculate the actual energy consumption of the device group group. In addition, as described in FIG. 2, the sensor 18 is installed on the upstream side of the energy supply or on the downstream side after the branching. Therefore, the sensor 18 that can measure the actual energy consumption of the device group group is specified, The measurement data may be stored as the actual energy consumption of the device group group.

  The related information database 36 stores standard energy consumption factor information for calculating the standard energy consumption of the device or the standard energy consumption of the device. This standard energy consumption is a consumption that serves as an index as to whether or not the actual energy consumption described above is consistent with operational requirements. For example, when the actual energy consumption is the same as the standard energy consumption, it is consistent with the operational requirements, and when it is small, the evaluation may be inconsistent with the operational requirements. it can.

  In the present embodiment, the energy consumption factor information for calculating the standard energy consumption, the energy consumption during operation, the estimated operation time of the device during a predetermined period, and the operation rate of the device during the predetermined period It is memorized every time.

  FIG. 4 is a diagram showing energy consumption factor information of the heat source pump shown in FIG. As shown in FIG. 4, the rated power consumption (KW / h) as the operating energy consumption 42, the operating time (h / month) as the estimated operating time 44 of the device in a predetermined period, and the operating rate 46 of the device in the predetermined period A load factor (operation rate) is set for each month.

The standard energy consumption is

[Equation 1]
Standard energy consumption = (energy consumption during operation of the device) x (estimated operation time of the device in a given period) x (operation rate of the device in a given period)

Can be calculated.

  Therefore, the standard energy consumption may be calculated in advance and the standard energy consumption may be stored.

  Next, each item will be described in detail.

  The energy consumption amount 42 at the time of operation of the device is an energy consumption amount that is consumed when the device exhibits its rated capacity, and is generally an energy consumption amount in an operation state with good energy efficiency. In the example of FIG. 4, the rated power consumption per hour is set.

  The estimated operation time 44 of an apparatus is an estimated operation time estimated that an apparatus will drive | operate in a predetermined period. For example, it is calculated based on 24 hours a day for hospital elevators, and for a commercial building such as a department store, for example, the business hours of department stores, for example, 12 hours a day from 10:00 to 22:00. In the example of FIG. 4, an estimated operation time of one month is set.

  Here, the device does not always operate with the energy consumption during operation during the operation time. For example, in the case of a device that performs intermittent operation that repeatedly stops operation when the temperature reaches a set temperature, such as an air conditioner, the above-described energy consumption during operation is not always consumed. Further, in the case of a device in which inverter control is performed according to load variation, the operating energy consumption varies according to inverter control. Therefore, more appropriate standard energy consumption is calculated by setting the operating rate in addition to the above operating energy consumption and estimated operating time for each device 16 according to the usage environment of the device and the load of temperature change. can do.

  Therefore, the operation rate is set in consideration of various situations. For example, in the air conditioner described above, the operation stop time when performing intermittent operation according to the set temperature load, change in outside air temperature, interpersonal or objective, and in the case of interpersonal, set by the number of people and the frequency of access Is done. Also, the use of the building, such as a hospital, office, school, etc., should be taken into account. When the inverter control is performed according to the load fluctuation, the operation rate is set according to the inverter control.

In the example of FIG. 4, the operation rate is set for each month, and since the device 16 is a heat source pump, the operation rate is different between summer and winter due to the influence of changes in the outside air temperature.
In addition, since it is thought that the estimated operation time and the operation rate of the devices 16 such as lighting are almost the same for each floor, they can be collected as one piece of information for each floor, for example, the group consumption factor of the device group group on the first floor It can be stored as information.

  The control device 28 includes an actual consumption acquisition unit 48, a standard consumption calculation unit 50, an actual operation rate calculation unit 52, and a display control unit 54. The control device 28 includes a CPU, a RAM, and a ROM, stores a control program, and operates on a general operating system (OS).

  The actual consumption acquisition unit 48 acquires the actual energy consumption. That is, the actual consumption acquisition unit 48 reads the measurement data from the measurement data database 34 according to a user input instruction or the like, performs predetermined processing, and acquires the actual energy consumption. When there is a user instruction for a device group group by floor, system, or usage, the attributes of the measurement data are distinguished, and an actual energy consumption is acquired by performing addition processing or the like as necessary. For example, when the first floor is designated by floor, the actual consumption acquisition unit 48 reads the energy consumption of the equipment having the attribute of the first floor from the measurement data database 34, adds them, and adds 1 Get the actual energy consumption of equipment groups on the floor. Further, when the first floor accumulated data is already stored in the measurement data database 34, the accumulated data is acquired and set as the actual energy consumption. Thereby, the processing speed with respect to a user instruction | indication can be shortened.

The standard consumption calculation unit 50 calculates the standard energy consumption of the device 16 to be evaluated. Specifically, from the related information database 36, the operating energy consumption 42 of the device specified by the user, the estimated operation time 44 of the device in a predetermined period, and the operation rate 46 of the device in the predetermined period are read out. And the standard consumption calculation part 50 calculates a standard energy consumption by the following formula 2.

[Equation 2]
Standard energy consumption = (energy consumption during operation of the device) x (estimated operation time of the device in a given period) x (operation rate of the device in a given period)

  When the device group group of the predetermined group is designated, the attribute of the related information database 36 is determined, the standard energy consumption is calculated for each device 16, the standard energy consumption for each device 16 is added, Calculate the standard energy consumption of the device group. Or when group consumption factor information is memorize | stored in a related information database, it calculates based on the information.

The actual operation rate calculation unit 52 calculates the actual operation rate of the device based on the standard energy consumption of the device, the actual operation time of the device, and the energy consumption of the device. When the standard energy consumption and the actual energy consumption are compared, the values may be greatly different. In this case, by calculating the actual operation rate, it can be confirmed to what extent there is an operational requirement for the device. In the calculation of the actual operation rate, the actual operation rate calculation unit 52 acquires the operation energy consumption 42 of the device from the related information database 36, and acquires the actual operation time and the actual energy consumption of the device from the measurement data database 34. To do. Then, the actual operation rate calculation unit 52 calculates the actual operation rate by, for example, the following formula 3.

[Equation 3]
Actual operation rate =
(Equipment operating energy consumption x equipment actual operating time) ÷ actual energy consumption

  As a result of the calculation, for example, if the actual operation rate is higher than the set operation rate, it can be evaluated that the device is operating efficiently. On the other hand, if the actual operation rate is low, the device is operated inefficiently. It can be evaluated that you are doing.

  The display control unit 54 outputs operation evaluation information for evaluating the actual energy consumption based on the standard energy consumption or the evaluation result. For example, the display control unit 54 outputs the actual energy consumption and the standard energy consumption so as to be comparable. Specifically, it is output in a table or graph format. It also outputs a trend graph of actual energy consumption and standard energy consumption. Note that the actual energy consumption and standard energy consumption of a plurality of device groups can be displayed simultaneously. Thereby, comparison of the actual energy consumption of the 1st floor and the 2nd floor can be performed. The actual energy consumption and the standard energy consumption may be compared and evaluated, and the evaluation result may be displayed.

  The input device 30 includes a keyboard, a mouse, and the like, and is given a user instruction input.

  The output device 32 includes a display, a printer, and the like, and outputs display contents processed by the display control unit 54.

  The operation of the device operation evaluation information providing apparatus will be described below. FIG. 5 is a diagram illustrating a screen until output of device operation evaluation information.

  As shown in FIG. 5A, the menu screen of the simplified energy analysis 60 is displayed on the display. This simple energy analysis 60 is a selection tool that provides operation evaluation information of this embodiment. Here, a device list table output 62 and a result output 64 are displayed. The device list table output 62 is a tool for displaying the energy consumption factor information described above, which will be described later.

  Next, when the result output 64 is selected, as shown in FIG. 5B, electric power 66 and heat 68 can be selected. When the electric power 66 is selected, the electric room 70 and the floor 72 can be selected as shown in FIG. When the electric room 70 is selected, several electric rooms can be selected as shown in FIG. 5D. For example, the B4 floor electric room 74 is selected and executed with the execution key 76. Thereby, as described above, predetermined processing is performed by each unit of the control device 28, and information for evaluating the actual energy consumption based on the standard energy consumption is output.

  FIG. 6 is a diagram showing an output result. As shown in FIG. 6 (A), a calculated value 78 and a measured value 80 are displayed for each device 16 (from the top, air heat source heat pump unit, heat source pump, etc.) to which power is supplied from the B4 floor electrical room in March. Has been. The calculated value 78 indicates the standard energy consumption, and the measured value 80 indicates the actual energy consumption. In this way, the standard energy consumption and the actual energy consumption are displayed so as to be comparable, so that the actual energy consumption can be evaluated in operation. For example, when the actual energy consumption is the same as the standard energy consumption, it is consistent with the operational requirements, and when it is small, the evaluation may be inconsistent with the operational requirements. it can.

  Further, when the trend graph 82 is executed, a trend graph 84 of the actual energy consumption and the standard energy consumption is displayed as shown in FIG. Thereby, transition of actual energy consumption can be predicted.

  Thus, after evaluating the actual energy consumption and standard energy consumption, the actual energy consumption and standard energy consumption are comparable and the equipment is consistent with the operational requirements. In order to reduce the actual energy consumption. In this embodiment, in such a case, it is possible to select a device list table output 62 and change the energy consumption factor information described above to simulate a change in energy consumption.

Next, as shown in FIG. 7B, when the B4 floor electrical room is selected, energy consumption factor information is displayed as shown in FIG. 7C. This table corresponds to the table shown in FIG. Here, the operating energy consumption 42, the estimated operating time 44, and the load factor (operating rate) 46 can be changed. For example, if the estimated operation time is changed, it is reflected in the evaluation result of FIG.
