Description

  The present invention relates to a system, method, and program for performing economical performance evaluation in a heat supply system.

  Conventionally, the economic evaluation of heat supply has been carried out by calculating COP (Coefficient of Performance) or efficiency from the amount of energy of electricity and gas, focusing on maintaining and improving the function of each device. For example, when supplying energy to a group of bases (hereinafter referred to as bases) as an energy supply unit such as a room, building or factory, electricity, gas, etc. are used as energy sources. In addition, various devices are installed in the base. Regarding the heat supply for the purpose of air conditioning, for example, the same heat supply amount is rare even in the same building floor. Therefore, even if the actual condition of the heat supply at the base is found out, it is rare that the actual condition of the heat supply at all the bases is the same. Moreover, in the heat supply using electricity and gas, water was actually consumed.

  In this way, when evaluating the economics of heat supply to a base, the amount of energy such as electricity and gas that minimizes the heat supply cost depends on the structure of the base building and the equipment installed. Therefore, it was necessary to evaluate the heat supply cost individually. The following three patent documents exist regarding the economic evaluation of heat supply, and various proposals have been made.

  First, Patent Document 1 formulates performances such as efficiency of heat source equipment and determines operating costs such as fuel consumption (electric power) charges in order to determine the operation method of heat source equipment that is economical and practical, at high speed. A method for pursuing economic efficiency using mathematical programming as an evaluation function and a method for creating a plant operation plan capable of creating an operation method for optimizing the evaluation function at high speed have been proposed. Patent Document 2 describes construction and operation maintenance based on the degree of heating and cooling thermal characteristics of the building itself, the consumption of fossil fuels including oil, gas and electricity, including the efficiency of equipment, and the future prediction of energy and economy. We have proposed an energy-saving performance evaluation system for homes that is designed to identify energy-saving homes by evaluating costs and social / global environmental impact and user convenience.

Patent Document 3 states that management control of air-conditioning heat source equipment requires the skill of the operation manager when carrying out optimal control of the air-conditioning heat source equipment from an economical or energy-saving viewpoint to reduce the workload of the operation manager. Therefore, it is possible to provide an air conditioning heat source equipment management control device that can objectively and rationally determine the operation manager's judgment criteria when carrying out management control, and that maintains the consistency of control and management of the air conditioning heat source equipment. Proposals are made for the purpose.

Yes.
The economic evaluation system for heat supply is configured as described above, and the operation will be described below.

  FIG. 2 shows the heat supply cost necessary for reducing the temperature by 1 ° C. in the first embodiment of the present invention. In the present embodiment, a combination of power and gas supply amount necessary for lowering the temperature by 1 ° C. from the specified temperature is shown, but a table may be given not only at 1 ° C. but also at several ° C. . In this figure, values obtained by actual measurement in advance are described.

  The relationship between the amount of power and gas supply can be expressed by a certain function. The current value and the temperature to be changed are input to the function. 2 can be used to fill the table of FIG. 2 if the supply amount of power and gas including the heat supply cost can be obtained.

  In FIG. 2, a combination of electric power and gas supply amounts including the cost of water supply required to lower the room temperature of a room from 30 ° C. to 29 ° C., for example, is described. From the top of the figure, the power amounts A301, A302, and A303 to be supplied are used, and the cost of each power consumption is 110 yen, 120 yen, 130 yen, 140 yen and more, The cost of tap water used for the amount of power used is assumed to be 10 yen, 11 yen, 12 yen, and 14 yen, respectively.

  In the present embodiment, “other power” is described when, for example, the basic contract fee is changed as a power fee due to exceeding a certain amount. The same applies to other gases.

  In FIG. 2, the gas supply amount and the gas fee corresponding to the supply amount, and the water fee and other gas fee corresponding to the water to be used when water is used are described. The water required to lower the temperature from 30 ° C to 29 ° C by adding the electricity charge including the water charge required for supplying the above power and the gas charge including the water charge required for supplying gas. The electric power and gas heat supply cost included in the heat supply cost can be obtained.

  From FIG. 2, it can be seen that in this embodiment, when the temperature is lowered from 30 ° C. to 29 ° C., the temperature can be lowered by a minimum of 329 yen if the power amount is A304 and the gas supply amount is B304. Although not shown in the drawing, the lowest value of the heat supply cost including water as a cost to lower or raise a certain temperature force 1 ° C., such as 29 ° C. to 28 ° C., is the same as that from 30 ° C. to 29 ° C. Can be determined.

  Further, in the present embodiment, it does not discuss how much time it takes to reduce the electric power and heat supply by 1 ° C., and it is defined with the lowest heat supply cost to lower 1 ° C. Is.

  FIG. 3 shows the transition of the amount of heat supplied to the room by the economic evaluation system for heat supply when the temperature is lowered from 30 ° C. to 25 ° C., for example. As shown in FIG. 2, when the temperature is lowered from 30 ° C. to 29 ° C., the power is A304 and the gas supply amount is B304. Next, the optimum power supply amount for lowering from 29 ° C. to 28 ° C. is A291, and the gas supply amount is B291. These values are obtained when a table from 29 ° C. to 28 ° C. is completed as shown in FIG. 2, and are assumed to be A291 and B291 in this description. The same applies to 25 ° C., and the optimum power supply amount for lowering from 28 ° C. to 27 ° C. is A288, and the gas supply amount is B288. To lower the temperature from 27 ° C. to 26 ° C., the supply amounts of power and gas are A275 and B275, respectively, and the optimal supply amounts of power and gas to decrease from 26 ° C. to 25 ° C. are A263 and B263, respectively.

  As described above, in this embodiment, the optimum supply amount of power and gas for lowering or raising the temperature of 1 ° C. can be determined, so that the manager of the heat supply supplies the supply of power and gas when the temperature is reached. By specifying the amount, it is possible to supply the heat amount at which the heat supply cost becomes the lowest value.

  This will be described in more detail with reference to FIGS. FIG. 4 shows the operation performed by the heat supply amount calculation means 134 in the heat supply amount control server 2 in this embodiment. A case where the air conditioner is operated by setting the room temperature to 25 ° C. when the room temperature is 30 ° C. will be described. The heat supply amount calculating means 134 is given a current room temperature of 30 ° C. and a target room temperature of 25 ° C. (S41).

  In this embodiment, since the data to be referred to is data for every 1 ° C., water for lowering the temperature from 30 ° C. to 29 ° C. is included as a heat supply cost using 29 ° C. obtained by subtracting 1 ° C. from 30 ° C. and 30 ° C. as a parameter. However, in order to calculate the optimum power amount and gas supply amount, the “routine for obtaining an appropriate power amount and gas supply amount for every 1 ° C.” shown in FIG. 5 is started (S42).

  In response to the output from the “routine for determining the appropriate amount of power and gas supply for every 1 ° C.”, the supplied amount of power and gas at which the obtained heat supply cost is the lowest value is output to the display 16 screen. (S43). It is determined whether or not the temperature has been reached to the target temperature. If not, the parameters are both set to minus 1 (S45), and the process returns to step S42. The “routine for obtaining an appropriate power amount and gas supply amount for every 1 ° C.” this time is operated with 29 ° C. and 28 ° C. as parameters (S42). This operation is repeated up to the target temperature (S44).

  When the temperature reaches the target temperature, the process ends (no route in S44). In the above, since it is from 30 ° C. to 25 ° C., the “routine for obtaining appropriate power amount and gas supply amount for every 1 ° C.” is started four times, and the obtained power and gas supply amount is displayed on the screen four times. become. In this embodiment, the screen is displayed. However, when it is desired to automatically perform processing, it is possible to notify other devices. Further, regarding the screen display, it is also possible to notify the result to a predetermined telephone number, FAX number, or e-mail.

  Next, a “routine for obtaining an appropriate power amount and gas supply amount for each 1 ° C.” will be described with reference to FIG. When activated, first, a reference temperature and a target temperature are acquired from parameters (S51). Next, refer to the combination of the amount of electricity and the amount of gas supply that includes water in the cost as energy required to lower the temperature of a room shown in FIG. 2 corresponding to the reference temperature and the target temperature from 30 ° C. to 29 ° C. For the first time, the power amount and gas supply amount at that time are set as the lowest prices (S52).

  Refer to the standard temperature table of 30 ° C. for heat supply cost and compare with the lowest value (S53). When it is cheap (S54), the reference electric power and gas supply amount are set as the lowest price (S55). If it is not cheap, nothing is done (S54). It is determined whether all combinations have been searched (S56). If all combinations are completed, the lowest power amount and gas supply amount are output (S57), and the process is terminated. If all the combinations have not been completed, the process returns to step S53 and the heat supply costs are compared again. As described above, the minimum power amount and gas supply amount at a certain temperature are determined.

  Next, an operation flow in the case where a temperature sensor is installed in a room, a floor, a building, etc. and is connected to the heat quantity supply control server 2 will be described. Similar to the description of FIGS. 4 and 5, the case where the temperature is lowered from 30 ° C. to 25 ° C. will be described. In FIG. 6, the part surrounded by the broken line on the left side is the sensor 5, the part surrounded by the broken line in the middle is the heat quantity supply control server 2, and the part enclosed by the broken line on the right side is the heat quantity supply device 3 that supplies power and gas. Represents.

  First, the sensor 5 senses the current temperature of 30 ° C. by the temperature sensing unit 55, and the communication control unit 56 notifies the heat quantity supply control server 2 (S61a). The heat supply control server 2 receives the temperature from the sensor 5 at the transmission / reception unit 12, and the temperature measurement unit 135 receives the temperature via the transmission / reception control unit 131. The temperature measuring means 135 notifies the heat supply amount calculating means 134 of the obtained temperature.

  Based on the received temperature (S61b), the heat supply amount calculating means 134 determines that the current temperature is a reference temperature and the target value is lowered to 25 ° C. (S62b). The heat supply amount calculation means 134 is shown in FIG. 5 in order to calculate a combination that minimizes the heat supply cost of the electric power amount and the gas supply amount necessary for lowering the temperature of the designated room from 30 ° C. by 1 ° C. Then, the “routine for obtaining an appropriate power amount and gas supply amount for every 1 ° C.” is used as a parameter to start up at a reference temperature of 30 ° C. and a target temperature of 29 ° C. (S63b).

  “Routine for determining the appropriate amount of power and gas supply for every 1 ° C.” refers to the table “Energy required for lowering the temperature of a room by 1 ° C. (heat supply cost)” shown in FIG. The combination of the amount of power and the amount of gas supply with the lowest heat supply cost is output. The heat supply amount calculation means 134 obtained from the “routine for obtaining an appropriate power amount and gas supply amount for each 1 ° C.” as the optimum power amount and gas supply amount uses the calculated power amount and gas supply amount to generate power. The gas supply device is instructed to operate by designating the temperature (S64b).

  Receiving the instruction (S61c), the power and gas supply device supplies heat to the room with the designated power amount and gas supply amount (S62c). Next, the sensor 5 senses 29 ° C. and notifies the heat supply amount control server 2 (S62a). Upon receipt of the fact that the room has reached 29 ° C., the heat supply amount calculation means 134 next sets the reference temperature to 29 ° C. and the target temperature to 28 ° C. The routine for determining the amount is started (S66b).

  “Routine for obtaining appropriate power and gas supply for every 1 ° C.” is the lowest power supply cost and gas supply heat required to lower the room temperature from 29 ° C. to 28 ° C. Calculate and output the value of The calorific value supply calculating means 134 which has acquired the optimum electric energy and gas supply amount for lowering the room temperature from 29 ° C. to 28 ° C. obtains the electric energy and gas supply obtained for the electric power and gas supply device in the same manner as described above. Instruct to operate with the amount (S67b).

  The power and gas supply device operates at the designated power amount and gas supply amount (S64c). Thereafter, similarly, the sensor 5 senses 28 ° C., 27 ° C., and 26 ° C. and notifies the heat supply control server 2 (S63a). The heat supply amount control server 2 that has received the notification receives the temperature from the sensor 5 (S68b), and operates in the same manner as described above. When the sensor 5 senses the target value of 25 ° C. and notifies the heat supply amount control server 2 (S64a), the heat supply amount calculation means 134 of the heat supply amount control server 2 determines that the target value has been reached. .

  Thereafter, an instruction to perform normal continuous operation is given (S6Ab). In the present embodiment, the continuous operation refers to an operation of continuing the temperature to the target value. The power and gas supply device receives an instruction (S65c) and performs a predetermined operation.

  In the above description, only the temperature reduction is described, but the table shown in FIG. 2 is prepared separately when raising the temperature, and when the temperature is raised based on the prepared table, the amount of power and gas supplied is the water supply. It is possible to cope with this by searching for a value at which the heat supply cost including the cost is the lowest and then operating as described above.

In addition, the table shown in FIG. 2 is performed by registering in the power information database (DB) 141 and the gas information database (DB) 142 using the input unit 15 and the display 16. Alternatively, it is also possible to create a file in advance by another computer or the like and import it into the database. Further, in FIG. 2, the power amount and the gas supply amount are registered as one information, but they may be registered separately and the heat supply amount calculation means 134 may refer to the information separately.
The first embodiment of the present invention is configured and operates as described above.

  According to the present invention, it is possible to calculate the lowest value of the heat supply cost including the cost of water supply for the amount of power and the amount of gas supply necessary to raise or lower the temperature from a certain reference temperature to the target temperature. In addition, if there is a sensor in the target room, it is possible to acquire the temperature from the sensor, automatically specify the optimal power amount and gas supply amount, and instruct the power and gas supply device to perform air conditioning It becomes.

  Next, a second embodiment of the present invention will be described below. In the second embodiment, a plurality of sections such as stores exist on one floor, and sensors are installed in the sections. In this case, it is difficult to bring the corners of the room to the target temperature using only the central air conditioning system. Therefore, when individual air conditioning equipment is installed in each section, it is possible to perform air conditioning in conjunction with individual air conditioning equipment at locations that have not reached the target value.

  FIG. 7 shows a configuration relating to heat supply of a floor with a building related to the second embodiment of the present invention. 21 is a building to which heat is supplied, and 211 is a floor of a certain floor. In the present embodiment, the floor 211 is provided with four sections 222a to 222d, and sensors 223a to 223d are provided respectively. Reference numeral 224 denotes a sensor provided for the heat supply device 3 which is a central air conditioning facility.

  FIG. 8 shows an operation flow when there is a central sensor and individual sensors. The operation flow when there are a plurality of sensors 5 and individual heat supply devices 31 will be described with reference to FIG. In FIG. 8, the center sensor 5, the individual sensor 5, the heat amount supply control server 2, and the individual heat amount supply device 31 are shown from the left side. The operations in steps S81a, S81a, S82a, S81c, and S82c are the same as those described in the first embodiment. In this situation, the central heat supply device is operating correctly because the floor temperature is lowered from 30 ° C to 25 ° C. However, depending on the shape of the floor, the temperature sensed by the sensors 223a to 223d shown in FIG. 7 may not reach 25 ° C.

  In this case, the heat amount supply control server 2 is notified of the temperature detected by the individual sensor 5, for example, 27 ° C. (S81b). The temperature measurement means 135 in the heat supply control server 2 receives that the temperature is 27 ° C. (S83c), and notifies the heat supply calculation means 134. The heat supply amount calculating unit 134 determines whether the notified value is different from the target value of 25 ° C. (S84c). When it is different from the target value, the place where the sensor 5 is installed is searched, and the corresponding individual heat supply device 31 is specified. Then, the individual heat supply control means 20 activates the identified individual heat quantity supply device 31 (S85c). If it is the same as the target value, do nothing.

  The individual heat amount supply device 31 receives an instruction from the heat supply amount calculating means 134 and starts supplying heat (S81d). Thereafter, when the fact that the temperature notified from the sensor 5 has reached the target value of 25 ° C. is received, the heat supply amount calculating means 134 instructs the continuous operation and ends.

In the present embodiment, the continuous operation refers to an operation of continuing the temperature to the target value. Further, in FIG. 8, only one sensor 5 and one individual heat quantity supply device 31 are shown, but when there are a plurality of sensors 5, the plurality of sensors 5 and the plurality of individual heat quantity supply devices 31 perform the same operation. A plurality of heat quantity supply control servers 2 may exist, but in this case, they operate in cooperation with each other.
