Description

  The present invention relates to a power management method and a power management apparatus. In particular, the present invention relates to a power management method and a power management apparatus (energy saving system) for saving power consumption by controlling air conditioning of a store (such as a pachinko store) when a demand system is used.

  In modern society, many air conditioners are used in various places, both for cooling purposes and for heating purposes. These air conditioners are installed in various places such as offices, factories, stores, public facilities as well as general residences. Air conditioners having various capabilities and characteristics are manufactured and sold in accordance with the characteristics of the place where they are installed and the size of the space. Such an air conditioner consumes a very large amount of power. For example, in general households and stores, there is data that air conditioning equipment consumes 20-30% of the power consumed by all electrical equipment (see, for example, Patent Document 1).

  Today, the power generation industry and the power generation situation are difficult due to the depletion of fossil fuels and the increase in regulations and opposition to nuclear power generation. In addition, to prevent global warming, regulations on power generation using fossil fuels and strict gaze tend to increase. On the other hand, the technological advancement and spread of power generation using renewable energy such as wind power generation and solar power generation still remain. For this reason, there has been a call for energy saving to reduce power consumption worldwide.

  Under such circumstances, the demand to introduce demand response (demand response) is increasing (for example, see Patent Documents 2 to 5). “Demand response” (DR) is a service such as dynamically setting charges so that the price of electricity rises during peak hours when demand is expected to be reduced, or returning points for saving electricity. By trying to promote the reduction of peak demand.

  Electric power companies are investing huge amounts of capital to meet peak demands of several tens of hours per year. If this peak demand can be reliably reduced, capital investment can be suppressed. In particular, US power companies with no investment capacity are actively investigating demand response. On the other hand, the need for demand response has not been so high in Japan. This is because before the earthquake, the electric power company provided a surplus supply to cover peak demand. However, since the shortage of power supply has become serious after the earthquake, and the rate of electricity has been increasing, the pace of introduction has increased.

  In addition, according to the Ministry of Economy, Trade and Industry, “Demand response” is “When the market price rises or the system reliability decreases, the consumer side controls the use of electricity according to the setting of the electricity price or payment of incentives. So as to change the power consumption pattern. In other words, the demand side can contribute to demand adjustment. To explain further, with the exception of some exceptions, supply and demand has been mostly done by the supply side. However, with the recent technological advancement, there is a system in place that allows the demand side to control and adjust power consumption. Therefore, demand response is attracting attention.

  Demand response is mainly classified into two applications. The first is “capacity”, which is generally positioned as a means of peak cut. In other words, it is a mechanism that encourages consumers to suppress the use of power through incentive compensation from power companies at the peak of power supply in summer and winter. The second is “balancing”, which is positioned as a means for balancing supply and demand in real time daily for stable power supply. The demand response as “capacity (peak cut)” assumes an operation prepared for an emergency, while the demand response as “balancing” assumes a normal operation.

Japanese Patent Laying-Open No. 2015-4444 JP 2017-127085 A JP 2017-147912 A JP 2014-236580 A JP2013-236520A JP 2001-197661 A

  As described above, various technologies have been proposed and improved due to the increasing demand for demand response. According to the study by the present inventor, this is suggested and improved from the demand response system construction side. As a result, it was concluded that there was a lack of consideration from the viewpoint of reducing power consumption and maintaining comfort in actual stores. First of all, air-conditioning equipment (air conditioners) consumes the largest amount of power in stores, and it is most important in power control to reduce power consumption by the air-conditioning equipment.

  The air conditioners currently on the market are provided with an inverter function in response to a decrease to a predetermined temperature or lower during cooling or an increase to a predetermined temperature or higher during heating. The inverter function reduces or stops the delivery of the cold air when the temperature becomes lower than a predetermined temperature while the cold air is delivered at a temperature set by the user during cooling, for example. The converse is true when the air conditioner is used as heating. It is considered that this inverter function can suppress the delivery of cold air or hot air that deviates from the set temperature, and as a result, can reduce power consumption.

  However, it is necessary to pay attention not only to the operation of the inverter function of the air conditioner but also to the contract power with the electric power company in order to reduce the power consumption and thus the electricity bill. That is, it is important not only to respond to power control required by demand response, but also to consider contract power while adjusting power consumption every hour and every day. Here, the contract power refers to a contract value of power supply between an electric power company (for example, Tokyo Electric Power, Kansai Electric Power, etc.) and an electric power consumer (for example, a store operator) (for example, (See Patent Document 6). What is used as a monitoring instrument for the contract power is the maximum demand power meter. In addition, since the measurement time is prescribed | regulated as 30 minutes by the electric supply contract, this is called the 30-minute maximum demand electricity meter. The demand power (demand) refers to the average power for 30 minutes determined by the electricity supply contract, and the maximum value for one month is referred to as the maximum demand power (maximum demand).

  For electricity consumers whose contract power is less than 500 kW, a so-called actual value contract is applied, and the contract power for the month is the maximum demand power (maximum demand) for the past year including the month measured by the maximum demand wattmeter. Automatically determined. Therefore, a power consumer whose contract power is less than 500 kW needs to prevent the demand from exceeding the contract, and can reduce the contract power by controlling the monthly maximum demand. And if contract electric power falls, it will become possible to save an electric bill according to it.

  On the other hand, when the value of the maximum demand wattmeter is 500 kW or more, based on the contents of the load equipment and power receiving equipment to be used, the load factor of the same industry, the operation rate, etc., between the power consumer and the power company The contract power will be determined through discussion. Currently, large-scale stores such as supermarkets, specialty stores, and department stores often have contract power of 500 kW or more. For such electric power consumers, demand control is required to reduce electricity charges.

However, if demand control is actually performed, the operation (output) of the air conditioning equipment is limited, so that the effectiveness of the air conditioning deteriorates, and there is a problem that people in the store (customers, staff, etc.) become uncomfortable. This is the same when the operation (output) of the air conditioner is restricted by the demand response. In the case of operation of air conditioning equipment at home, it is only necessary to endure discomfort, but in the case of a store, if the customer feels uncomfortable, the performance at that store will deteriorate and the reputation of the store will deteriorate, and in the future sales May also have adverse effects. Therefore, the reality is that store managers and managers are not aggressive in introducing demand control and demand response in stores. In addition, not only the customers, and effectiveness of the air conditioning is bad, in order to even worse working environment of staff, greater problem at that point.

  The present invention has been made in view of such points, and its main purpose is to perform air-conditioning control that does not feel uncomfortable even if the operation (output) of the air-conditioning equipment is limited by the demand response system, It is an object of the present invention to provide a power management method and a power management apparatus that save power consumption.

Even in the case where the effectiveness of the inverter becomes worse, “in the process of calculating the control frequency of the inverter motor, the control frequency is shorter than the fastest arrival control frequency that is the control frequency that reaches the air conditioning set temperature in the shortest time. Since the number of revolutions that reaches the air conditioning set temperature is calculated, the time to reach the set temperature will be delayed, but the effectiveness of the air conditioning will not deteriorate, so you can avoid feeling uncomfortable and ensure comfort And, at the same time, the maximum demand value can be suppressed, and as a result, the electricity bill can be significantly reduced. In other words, according to the present invention, even when there is a demand response power suppression instruction and the effectiveness of the air conditioning becomes worse, it is possible to eliminate the ineffectiveness of the air conditioning and not to feel uncomfortable. The demand value can be controlled, and therefore a great saving in electricity costs can be achieved while being a comfortable conditioned space.

Conveniently, it is possible to execute power suppression for demand response without changing to a device) and to reduce the electricity bill by controlling the maximum demand value.

  In addition, in the present invention, when not only the control of the air conditioner device but also the control linked with the ventilator device is performed, the electricity bill can be further reduced. Specifically, the ventilation volume adjustment system connected to the ventilation device includes a function of calculating a ventilation ratio from the operation rate data, a function of controlling the ventilation device based on the ventilation ratio, and When the inverter frequency adjustment system connected to the air conditioning equipment including the inverter motor has a function of calculating the control frequency of the inverter motor from the ventilation ratio and a function of controlling the inverter motor based on the control frequency.

  Before describing the details of the embodiment of the present invention, “demand response” will be described. As mentioned above, “demand response” means “when the market price rises or the system reliability declines, the consumer side will suppress the use of electricity according to the setting of the electricity price price or payment of incentives. To change the power consumption pattern. " The background of demand response is the “simultaneous same amount principle” which is one of the basic policies of electric power companies. This means that the demand amount and supply amount of power must be instantaneously matched, and it is an obligation to stably supply power by matching the demand amount and supply amount of power.

  In order to maintain this supply and demand balance, there are two ways of thinking: “Adjust the supply amount to the demand amount” and “Adjust the demand amount to the supply amount”. The former “matching the supply amount to the demand amount” has been performed by electric power companies so far, but each electric power company needs to prepare power generation facilities in excess of the supply amount. This excessive power generation facility results in high electricity costs due to the increased operating costs despite the low availability. On the other hand, the latter “matching the demand amount with the supply amount” is a new concept, and this is the concept of “demand response”. This means that the supply side can easily match the supply amount with the supply amount by generating surplus power by seeking cooperation from the consumer side according to the power situation.

  The demand response is roughly classified into two types according to the demand control method. One is a demand response (electricity charge type) based on electricity charges. This is a mechanism that encourages households and businesses to reduce power demand by raising electricity charges during peak hours of demand. This advantage is relatively simple and can be applied to the majority. This disadvantage is uncertain as to how much the surplus power will be affected by the customer's reaction.

  The other is incentive-based demand response. This is a mechanism for obtaining compensation when a power saving contract is made with an electric power company in advance and power is saved in response to a request from the electric power company. Since this advantage is contracted in advance, a certain amount of power saving effect can be expected. This drawback is relatively time consuming and difficult to apply to small consumers.

  FIG. 1 and FIG. 2 are block diagrams for explaining the mechanism of the incentive based demand response 300. Here, the “demand response (300)” is a mechanism (method) of power suppression and is used in the meaning of both of the systems that construct the mechanism.

  The incentive-based demand response 300 in FIG. 1 indicates that the electric power company 99 (or the program installer (electric power company, system operator)) has signed a contract with the customer 95, and the wholesale power price has risen or the power supply / demand It is a framework for carrying out load control / blocking when there is pressure. The customer 95 makes a request (contract) 301 for load suppression / load cut-off to the electric utility 99, and the electric utility 99 gives the customer 95 benefits such as a fixed amount grant and discount during the load cut-off period ( Monetary merit) 302. Thereby, the load at the time of a peak can be suppressed. That is, it is possible to improve economy by load leveling (peak cut).

  The incentive-based demand response 300 in FIG. 2 uses a negawatt trading mechanism, and trades through the demand adjustment market 97, assuming that the demand reduction amount by the customer 95 (95A to 95D) is a supply amount. It is a form. The aggregator 96 collects the adjustment amounts of the plurality of consumers 95 (95B to 95D). The customer 95 performs a negawatt transaction (311, 312, 313). Here, the customer 95 </ b> A performs a negawatt transaction 311 for the power generation company (system operator) 98 or performs a negawatt transaction 312 for the demand adjustment market 97. Then, the customers 95 </ b> B to 95 </ b> D perform a negawatt transaction 313 with the aggregator 96. The aggregator 96 performs a negawatt transaction 314 in the demand adjustment market 97 or performs a negawatt transaction 316 in the power generation company 98. Then, the demand adjustment market 97 performs a negawatt transaction 315 with the power generation company 98.

  On the other hand, the power generation company 98 gives a merit (monetary merit) 321 to the customer 95 </ b> A, gives a merit 325 to the demand adjustment market 97, or gives a merit 326 to the aggregator 96. Further, the demand adjustment market 97 gives a merit 322 to the customer 95 </ b> A or gives a merit 324 to the aggregator 96. And the aggregator 96 provides the merit 323 to the some consumers 95B-95D.

  By such a mechanism (demand response 300), by balancing the flow of services (negawatt transaction) and the movement of money, in other words, ensuring system reliability through the supply and demand adjustment market (and / or aggregator), Economic efficiency can be improved.

Examples of demand response methods (menus, programs) on an incentive basis include the following.
(1) Direct Load Control
A method in which the program installer remotely shuts down or circulates electrical equipment such as the air conditioner of the customer based on the previous notification (2) Interruptible Load
Menu that reduces or cuts off electricity usage charges under a contract that provides discounts, etc., instead of allowing customers to agree to reduce the burden in the event of an unforeseen system (3) Load as Capacity Resource

  FIGS. 3A to 3D are graphs for explaining the mechanism of demand response based on electricity charges. Demand response based on electricity charges allows electric utilities to set charges according to time periods (or hours), and to suppress demand at high loads when expensive charges are set for consumers at their own discretion. It is a framework that encourages demand shifts at low loads with reasonable prices. In this framework, toll signals will be notified by the previous day.

  FIG. 3 (b) shows a menu of peak charge (CPP: Critical Peak Pricing). In this case, a unit price 332 that is applied only to critical or peak days is set.

  FIG.3 (c) has shown the menu of the peak day rate (PDP: Peak Day Pricing). In this case, a unit price 334 (334a, 334b) that is applied only to the critical peak day is set together with the unit price 333 other than the critical peak day.

  FIG. 3D shows a real time pricing (RTP) menu. The unit price of the charge fluctuates (335) corresponding to the balance between supply and demand.

  Demand response (or demand response system) reduces the burden on electric power companies and power generation companies and optimizes electricity charges. This demand response is an important and preferable system. The present inventor has noticed that there are the following problems in actual operation. First, if the output of the air-conditioning equipment is restricted by the demand response instruction (invocation) and the effectiveness of the air-conditioning (air-conditioner) deteriorates, the comfort in the store is impaired. In other words, if customer comfort or staff comfort is impaired, it will lead to a decline in sales and reputation. Then, even if the electricity bill can be saved, it is imagined that there will be stores that do not introduce demand response due to fear of sales and reputation decline. The inventor of the present application has created a mechanism capable of reducing the electricity bill while using the demand response together without compromising the comfort even under such a demand response usage condition, and has reached the present invention.

For example, the server device 15) may be used.

  If the security is firm, an information terminal (computer device) that can be connected to the Internet (communication network) 90 instead of the server device 15 may be a system cooperation control device. Such an information terminal is typically a personal computer (PC), a communication device (for example, an optical fiber connection terminal or a wireless connection terminal) that can be connected to the Internet (communication network) 90, and a display device. (For example, liquid crystal display device), input device (for example, keyboard, mouse, etc.), arithmetic device (for example, semiconductor integrated circuit device (IC) or central processing unit (CPU)), storage device (for example, hard disk, semiconductor memory device) Etc.). Further, the information terminal is not limited to a personal computer (PC), and may be another device as long as the above-described cooperation control can be operated. For example, the information terminal is a smartphone, a tablet terminal, a mobile phone, or the like. Also good. Further, the information terminal may be connected in an information communication manner through another communication line, that is, an in-house LAN (wired LAN or wireless LAN) without being connected to the Internet 90.

  Store congestion level data can be input to the system cooperation control device 55 of the present embodiment. Store congestion level data is 100% for the maximum congestion such as full or full (or “10” for 10-level display), and 0% for the minimum congestion when no one is present ( “1” or “0” in the case of 10-level display). The store congestion level data may be input by the staff using an input device with his / her hand, or may be input using a smartphone or the like if remote input is possible. Alternatively, when store congestion level data can be automatically tabulated from information on customers sitting on pachinko machines, the automatically tabulated store congestion level data can be used.

(3a) A function for calculating the ventilation ratio from the store congestion level data, and (3b) a function for calculating the control frequency of the inverter motor 24 from at least one of the store congestion level data and the ventilation ratio.

  Regarding the function (3a), the “ventilation ratio” corresponding to 100% to 0% of the store congestion level is determined as empirical or processing data (for example, conversion table data) and can be processed. For example, when the ventilation ratio (or the required ventilation rate per hour) at the maximum congestion (100%) is 8 times (8 cups), the ventilation rate (the required ventilation rate per hour) at the congestion level (50%) Set the store congestion level data to 4 times (8 cups), and the congestion level (20%) ventilation ratio (necessary ventilation frequency) will be 1.6 times (1.6 cups) As described above, the level data at the time of store congestion can be set.

  For function (3b), the speed of the refrigerant gas calculated from the ventilation ratio obtained in function (3a) (that is, the speed of the refrigerant gas passing through the pipe 60a in FIG. 1) is calculated, and the speed of the refrigerant gas is calculated. The control frequency of the corresponding inverter motor 24 is calculated. In the function (3b), an arithmetic circuit (or conversion table process) that executes data processing (or programming) that can calculate the control frequency of the inverter motor 24 from store congestion level data may be constructed.

  Then, the system cooperation control device 55 transmits the calculated control frequency data to the inverter frequency adjustment system 30.

At the same time, the system cooperation control device 55 transmits the calculated control frequency data to the inverter frequency adjustment system 30. The ventilation volume adjustment system 70 can control the ventilation device 61 based on the transmitted ventilation ratio.

  Here, when the store congestion level is low (for example, 50%) and the ventilation ratio can be lowered (for example, 8 times → 4 times), the air-conditioning set temperature (for example, 26 ° C.) can be cooled. Therefore, the control frequency of the inverter motor 24 can be lowered (for example, the inverter motor control frequency that results in 50% operation). As a result, the power saving effect ( Or, the electricity bill saving effect) can be achieved. In addition, when the store congestion level is lower (for example, 20%) and the ventilation ratio can be further decreased (for example, 8 times → 1.6 times), the same air conditioning set temperature (for example, 26 ° C.) However, most of the cold air (or warm air) does not need to be discharged to the outside, so that the control frequency of the inverter motor 24 can be further reduced (for example, an inverter motor that achieves 20% operation). Control frequency), and as a result, a greater power saving effect (or electricity cost saving effect) can be obtained.

  In the technology so far, the reduction of power consumption in air-conditioning equipment has been measured by improving the performance of inverter functions and demand control functions, and the actual situation is competing for performance improvement. However, if the power management apparatus 100 according to the present embodiment is used, it is possible to achieve a significant energy saving effect as compared with the energy saving using the inverter function and demand control of high-level technology as long as it can be considered at present. The electricity bill of the store 50 can be significantly reduced.

  More specifically, in the power management apparatus (energy saving system) 100 according to the present embodiment, the ventilation amount adjustment system 70 connected to the ventilation device apparatus 61 has a function (1b) for calculating the ventilation ratio from the operation rate data, and the ventilation ratio. And an inverter frequency adjustment system 30 connected to the air conditioner device 20 including the inverter motor 24, the control frequency of the inverter motor is calculated from the ventilation ratio. It has a function (2b) to calculate and a function (2c) to control the inverter motor based on the control frequency. Thereby, according to the operation rate of the store 50, the ventilation ratio and the control frequency of the inverter motor can be controlled in conjunction with each other. As a result, power consumption in the store 50 such as a pachinko store can be saved. . In addition, the system cooperation control device 55 of the present embodiment has a function (3a) for calculating the ventilation ratio from the store congestion level data and a function (3b) for calculating the control frequency of the inverter motor 24. Similarly, the ventilation ratio and the control frequency of the inverter motor can be controlled in conjunction with the operating rate of the store 50, and as a result, power consumption in the store 50 such as a pachinko store can be saved. .

  Next, an example of the power management method of the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart for explaining the power management method of the present embodiment. The power management method of the present embodiment is executed by the power management apparatus 100 shown in FIG. 4 (or FIG. 5), and in particular, executed mainly by the inverter frequency adjustment system 30.

  First, as shown in FIG. 6, first, a demand response instruction (transmission of power suppression instruction data) from the aggregator 96 is executed (step S100). In the configuration example of the present embodiment, the inverter frequency adjustment system 30 is connected to the communication network 90 via the line 109. Therefore, even if the hall computer device 55 is powered off, a demand response instruction (power suppression instruction data) Can be received. The demand response instruction (power suppression instruction data) includes information requested by the demand response 300, for example, information on a demand response technique (menu, program) on an incentive basis. The demand response instruction (power suppression instruction data) may include information on demand response based on electricity charges.

  Then, the inverter frequency adjustment system 30 acquires an air conditioning temperature setting value (for example, a remote controller setting temperature or a setting temperature input by the hall computer device) of the air conditioner 20 (step S200). Note that the order of receiving the demand response instruction (S100) and obtaining the set temperature set value (S200) may be either first or simultaneous.

  Subsequently, the control frequency of the inverter motor 24 is calculated based on the power suppression instruction data and the air conditioning set temperature (step S300). In this control frequency calculation step, first, a control frequency that reaches the air conditioning set temperature is calculated under a constraint that satisfies the conditions required by the power suppression instruction data. In the step of calculating the control frequency, the number of revolutions that reaches the air conditioning set temperature in a time later than the fastest arrival control frequency that is the control frequency that reaches the air conditioning set temperature in the shortest time is calculated as the calculated control frequency. . Although details will be described later, the frequency (the air conditioning set temperature) that reaches the temperature (air conditioning set temperature) later than the arrival time achieved by the “fastest arrival control frequency” (frequency of the full power of the air conditioning equipment) is smaller than the full power. Frequency) ”is calculated. For example, in an automobile, the inverter motor 24 is controlled not in the fastest full power sports mode but in an eco mode that takes time but has good fuel efficiency. In addition, since the power suppression instruction data is received in advance (typically by the previous day), the inverter frequency adjustment system 30 has the inverter motor 24 set earlier (at an earlier time) than when operating at full power. A reservation operation can be performed to turn on the operation. Note that this control frequency calculation step (step S300) may be calculated by the inverter frequency adjustment system 30, or other calculation devices (for example, the management server 15, the hall computer device 55, the information terminal 16 of the management company 10). And the result may be transmitted to the inverter frequency adjustment system 30.

  Next, based on the calculated control frequency, the inverter frequency adjustment system 30 controls the inverter 24 (step S310). Subsequently, the inverter frequency adjusting system 30 collects data including demand values during operation (for example, air conditioning data, power consumption data, demand upper limit data, system operation data, etc.) and transmits the data. (Step S400). The transmitted data can be displayed on an information processing device (for example, management server 15, information terminal 16, hall computer device 55, etc.) (step S500).

  Next, the power management apparatus 100 according to the present embodiment will be described in more detail with reference to FIGS.

A configuration for executing a function (2a-2) for reading a frequency and a function (2c-2) for controlling the inverter motor 24 based on the control frequency is provided.

  In the configuration of the present embodiment, a touch panel is provided on the control circuit board 35 so that it can be directly operated by the inverter frequency adjustment system 30 instead of from the hall computer device 55 (or another computer device).

Note that the configuration example (display example / control screen example) of the touch panel 35 of the control circuit board is not limited to that shown in FIG. 8, and other configuration examples may be adopted. In addition, the hall computer device 55 (or another input device) may be used for control / instruction / display without providing the touch panel 35.

  FIG. 9 shows another configuration example of the inverter frequency adjustment system 30 of the present embodiment. The inverter frequency adjusting system 30 shown in FIG. 9 is a simpler version and smaller than the one shown in FIG. The inverter frequency adjustment system 30 shown in FIG. 9 can also execute the function described in FIG.

  FIG. 10 shows a ventilation control system including the ventilation volume adjustment system 70 of the present embodiment. The ventilation control system shown in FIG. 10 includes a hall computer device 55, a touch panel 75 for operating the ventilation amount adjustment system 70, a ventilation amount adjustment system 70, and a ventilation fan 62. In the configuration shown in FIG. 6, a command (signal) 73 from the hall computer device 55 is output to the touch panel 75, and a command (signal) 79 from the touch panel 75 is output to the ventilation adjustment system 70. A command (control signal) 77 from the ventilation amount adjustment system 70 is output to the ventilation fan 62.

  The ventilation volume adjustment system 70 shown in FIG. 10 is connected in information communication with the touch panel 75 by a wireless line. The touch panel 75 shown in FIG. 10 may be the same as the touch panel 54 shown in FIG. Further, the ventilation volume adjustment system 70 and the touch panel 75 may be connected in an information communication manner with a wired circuit, or the hall computer device 55 (or another computer device, touch panel device or smartphone device without providing the touch panel 75). ). The ventilation amount adjustment system 70 according to the present embodiment includes a casing (including a door) and a control circuit board disposed in the casing. The ventilation volume adjustment system 70 shown in FIG. 10 includes a wireless signal receiving unit from the touch panel 75. The connection between the ventilation amount adjustment system 70 and the ventilation fan 62 may be wired or wireless. When a plurality of ventilation fans 62 are attached (for example, 62a to 62d), a command (for example, 77a to 77d) for individually controlling the ventilation fans 62 can be transmitted.

  The control circuit board of the ventilation volume adjustment system 70 in this embodiment has a function (1a) for reading operation rate data from the hall computer device 55; a function (1b) for calculating a ventilation ratio from the operation rate data; a ventilation fan based on the ventilation ratio The function (1c) for controlling 62 (ventilation device 61) can be executed. The function (1a) for reading the operation rate data may receive the operation rate data via the touch panel 75. Further, when the system cooperative control device 55 of the present embodiment has a function of calculating the ventilation ratio from the store congestion level data, the control circuit board of the ventilation amount adjusting system 70 obtains the ventilation ratio from the hall computer device 55. It can be set as the structure which performs the function (1c) which controls the ventilation fan 62 (ventilation apparatus apparatus 61) based on the function (1a-2) to read and the ventilation ratio.

  11 and 12 show an example in which a plurality of air conditioning indoor units 60 (60a to 60d) are installed in the store 50. The store 50 is divided into a plurality of areas (or rooms) 50a to 50f. Here, the area 50a is an office room, the area 50b is a toilet, the area 50c is a rest room, the area 50d is a smoking corner, and the area 50e is The entrance / exit area, area 50f is a prize corner, and the central area is a hole. In this example, the store 50 is divided into four zones (50A to 50D), and two air conditioning indoor units 60 (60a to 60d) are installed for each zone. Each air conditioning indoor unit 60 (60a to 60d) mainly performs air conditioning (cooling or heating) of each zone (50A to 50D).

  In the illustrated configuration example, each air conditioning indoor unit 60 (60a to 60d) is connected to the air conditioning outdoor unit 29 (29a to 29d) via a pipe 60a. Each air conditioning outdoor unit 29 (29a-29d) is provided with a fan 21 and an inverter motor 24. The inverter frequency adjustment system 30 is connected to the air-conditioning outdoor unit 29 (29a to 29d) via the wiring 38. The inverter frequency adjustment system 30 of the present embodiment performs setting of the air conditioning indoor units 60 (60a to 60d) in each of the zones 50A to 50D (setting of the operating frequency of the inverter motor 24), and air conditioning of the zones 50A to 50D. Can be done individually.

  FIG. 11 shows a case where the zone control is not performed in the power management apparatus 100 of the present embodiment. In each of the zones 50A to 50B, the rotational speed control (inverter motor frequency control) is performed at 70% when the maximum output is 100%. )It is carried out. This rotation speed control (inverter motor frequency control) is determined not only by the set temperature of the air conditioner (and / or demand data for energy saving), but also the operation rate data of the store (or store congestion level data). ).

  Even in the state shown in FIG. 11, appropriate air conditioning control is performed based on the operation rate data. However, the store 50 has a zone with a large temperature change (for example, 50D) and a zone with a small temperature change (for example, 50D). For example, there is 50A). A zone with a large temperature change (for example, 50D) is a place near an entrance, a place exposed to direct sunlight, a place where people gather. A zone with a small temperature change (for example, 50A) is a place far from the entrance / exit, a place not exposed to sunlight, and the like.

  FIG. 12 shows a case where zone control is performed in the power management apparatus 100 of the present embodiment. In the example shown in FIG. 12, 80% rotation speed control (inverter motor frequency control) is performed in a zone (50D) where the temperature changes frequently, and the air conditioning in that zone (50D) is strengthened to increase the comfort level. ing. On the other hand, in the zone (50A) where the temperature change is small, 60% rotation speed control (inverter motor frequency control) is performed to weaken the air conditioning in the zone (50A) to save air conditioning energy consumption.

  11 and 12, the inverter motor frequency control (rotational speed control) is 60%, 70%, or 80%, but 1% in the energy saving system 100 (inverter frequency adjustment system 30) of the present embodiment. Frequency control can be set for each. Moreover, it is also possible to set the time (time) controlled by the energy saving system 100 (inverter frequency adjustment system 30) by timer setting. 11 and 12, the zone controls 50 </ b> A to 50 </ b> D of the indoor air conditioner 60 and the outdoor air conditioner 29 (air conditioner device 20) by the inverter frequency adjustment system 30 have been described. It can also be implemented for the zone controls 50A to 50D of the ventilation fan 62 (ventilation device 61). Of course, the zone controls 50 </ b> A to 50 </ b> D by the cooperation of both the inverter frequency adjustment system 30 and the ventilation amount adjustment system 70 can be implemented.

  FIG. 13 is a flowchart illustrating an example of a usage method (operation method) of the power management apparatus (energy saving system) 100 according to the present embodiment. The power management apparatus 100 described in this example can control both the inverter frequency adjustment system 30 and the ventilation volume adjustment system 70 in cooperation, and the operation under the conditions of the demand response 300 is as described above. Therefore, description of the overlapping part is omitted.

  As shown in FIG. 13, first, the operation of the ventilation volume adjustment system 70 is started (step S200), and then the operation rate is read from the hall computer 55 (step S210). Here, the operating rate is represented by, for example, 0% to 100% (or 0% to 120%, etc.). Next, it is determined whether the operation rate has been successfully read into the ventilation adjustment system 70 (step S220). As a result of the determination, if the reading is successful (Yes), the ventilation ratio is calculated by the ventilation control by the control circuit board of the ventilation adjustment system 70, and the ventilation fan is calculated with the ventilation ratio (for example, 0% to 100%). 62 and / or the damper 68 are controlled (step S230). If the reading fails as a result of the determination (No), the process returns to step S210 again to read the operation rate from the hall computer 55.

  Then, in parallel with the operation of the ventilation volume adjustment system 70, the operation of the inverter frequency adjustment system 30 is started (step S300), and then the ventilation ratio is read from the ventilation volume adjustment system 70 (step S310). Next, it is determined whether the ventilation ratio has been successfully read (step S320). If the reading is successful as a result of the determination (Yes), the refrigerant gas speed is controlled (motor frequency control) by calculating from the ventilation ratio (step S330). If the reading fails as a result of the determination (No), the process returns to step S310 again to read the ventilation ratio.

  When stopping the operation of the energy saving system 100, the control switch of the ventilation adjustment system 70 in operation is turned off (step S240), and when it is turned off (Yes), the process is finished (step S250). If not, the process returns to the reading step (S210) and the process is repeated until the operation stops. Similarly, in parallel, the control switch of the operating inverter frequency adjustment system 30 is turned off (step S340), and when it is turned off (Yes), the process is ended (step S350). If not, the process returns to the reading step (S310) and the process is repeated until the operation stops.

In the method of this embodiment, based on the operation rate data (or store congestion level data) of the store 50, both the inverter frequency adjustment system 30 and the ventilation amount adjustment system 70 are operated in cooperation to achieve air conditioning. The air in the store (cooled or heated air) is executed while controlling appropriate air conditioning while preventing the air from being thrown out more than necessary. Thereby, the energy saving effect (electricity cost saving effect) which could not be exceeded by the conventional technology (high performance air conditioning technology) can be realized. In the flowchart shown in FIG. 13, the ventilation ratio is calculated by the ventilation amount adjustment system 70. However, as described above, the ventilation rate is calculated by another arithmetic device (for example, the hall computer device 55 or another computer device). After calculating the ratio and / or the adjusted inverter frequency, the ventilation volume adjustment system 70 and the inverter frequency adjustment system 30 may be operated in cooperation.

  Next, the effect of saving (decreasing) the air-conditioning electricity cost by the power management apparatus (energy saving system) 100 of the present embodiment will be described with reference to FIGS.

  FIG. 14A shows the configuration of the air conditioning equipment device 20 including the air conditioning indoor unit 60 and the air conditioning outdoor unit 29. FIG. 14B shows the inverter motor 24 in the compressor 25 provided in the air-conditioning outdoor unit 29. FIG. 14C is a graph showing the time from the switch ON (98) of the air conditioner device 20 to the arrival of the air conditioning set temperature (99).

  On the other hand, FIG. 15A shows an inverter motor 24 via an adapter (inverter motor control frequency adapter) 22 with the inverter frequency adjustment system 30 of the present embodiment added to the air conditioner outdoor unit 29 having the configuration shown in FIG. The configuration connected to is shown. Similarly, FIG. 15B shows the inverter motor 24 in the compressor 25 provided in the air conditioner outdoor unit 29. FIG. 15C is a graph showing the time from the switch ON (98) of the air conditioner device 20 to the arrival of the air conditioning set temperature (99).

  Here, a case where the room temperature is set to the set temperature (cooling temperature) as early as possible in midsummer will be described as an example of air conditioning of the store 50. An explanation will be made assuming that the temperature in the store when the air conditioner is not activated is 30 ° C. and the temperature when activated is 26 ° C. (air conditioner set temperature). In addition, when heating in midwinter, it can be understood as the reverse explanation.

  First, as shown in FIG. 14 (a), when the air in the store 50 is cooled (air-conditioned), the air-conditioning indoor unit 60 sucks in the store air (room temperature) (arrow 91), and is 5 below the room temperature. Cooling air whose temperature has been lowered by about 0.degree. And the refrigerant | coolant in the pipe 60a extended outside the shop 50 from the air-conditioning indoor unit 60 conveys the deprived heat toward the compressor 25 (arrow 93). As shown in FIG. 10B, the refrigerant (94) moves (downstream) by the operation of the inverter motor (compressor inverter motor) 24 in the compressor 25, and then, as shown in FIG. In addition, the deprived heat is released to the outside through the fan 21 (arrow 95). Thereafter, the refrigerant that has released the heat (cold refrigerant) proceeds through the pipe 60 a as indicated by an arrow 96, and then enters the store 50 as indicated by an arrow 97. Then, the heat is again taken through the air conditioning indoor unit 60, and the taken heat is taken out of the store 50 as indicated by an arrow 93. By repeating this operation, the inside of the store 50 is cooled.

  The most important thing in saving electricity costs for an air conditioner (air conditioner) is the power (energy consumption) of the inverter motor 24, which accounts for 90% of the air conditioner power. However, if it is a home air conditioner, you can use the method of putting up the air conditioner even in midsummer (or lowering the set temperature of the air conditioner), but the stores that customers visit (especially pachinko stores) 50 However, not cooling the air conditioner in mid-summer (or raising the set temperature above the comfortable temperature) will also affect the number of customers, sales, and the reputation of the customer. It cannot be changed (that is, set to a higher set temperature). Therefore, we will introduce a commercial air conditioner with high power-saving effect, but even though it can still achieve a certain level of power-saving effect, it does not provide a significant effect (an effect that can save millions of yen in electricity costs in one year). Was the actual situation.

  As shown in FIG. 14C, when the air conditioner switch is turned on at 8 am, the inverter motor 24 is fully operated (100% rotation) toward the air conditioner set temperature, and the set temperature at 10 am after 2 hours. To reach. If 10:00 am is the opening time of the pachinko store, the air in the store 50 is harmonized at the set temperature from there, so that customers can play comfortably.

  On the other hand, when the inverter frequency adjustment system 30 of this embodiment is connected to the inverter motor 24 and controlled, the operation is as follows. As shown to Fig.15 (a), the air (room temperature) in a store is inhaled by the air-conditioning indoor unit 60 (arrow 91). At this time, in FIG. 14A, the cooling air 92 having a temperature lower by about 5 ° C. than the outside air was discharged. In FIG. 14A, the cooling air 92 having a temperature lower by about 4.2 ° C. was discharged. Is discharged. That is, the cooling air 92 which is higher by about 0.8 ° C. than that of FIG. This slight difference is the key to a large power saving effect.

  14 (a) and 14 (b), the refrigerant in the pipe 60a extending from the air conditioner indoor unit 60 to the outside of the store 50 also takes the heat taken away in the case of FIGS. 15 (a) and 15 (b). Carry toward the compressor 25 (arrow 93). As shown in FIG. 15 (b), the refrigerant (94) moves (downstream) by the operation of the inverter motor (compressor inverter motor) 24 in the compressor 25, and then, as shown in FIG. 11 (a). In addition, the deprived heat is released to the outside through the fan 21 (arrow 95). Thereafter, the refrigerant that has released the heat (cold refrigerant) proceeds through the pipe 60 a as indicated by an arrow 96, and then enters the store 50 as indicated by an arrow 97. Then, the heat is again taken through the air conditioning indoor unit 60, and the taken heat is taken out of the store 50 as indicated by an arrow 93. By repeating this operation, the inside of the store 50 is cooled.

  15 (a) and 15 (b), the cooling air 92 that is about 0.8 ° C. higher than that in FIG. 14 (a) is discharged, so that the rotational speed (control of the inverter motor 24) is controlled. The frequency is slightly lower. Accordingly, as shown in FIG. 15C, when the air conditioner switch is turned on at 8:00 am, the inverter motor 24 is rotated at a slightly saved rotational speed (saved rotation less than 100%) toward the air conditioner set temperature. The set temperature is reached at 10:30 am after 2 hours and 30 minutes. That is, compared with the operation of FIG. 14A, the set temperature is reached later by 30 minutes. If 10:30 am is the opening time of the pachinko store, the air in the store 50 is harmonized at the set temperature from there, so that customers can play comfortably. If the opening time is 10:00 am, the switch is turned on at 7:30 am. Here, in the case of the difference between the two cars, the operation in FIG. 10A is the normal mode, and the destination is reached quickly with an emphasis on speed (in other words, the set temperature is quickly reached). On the other hand, the operation of FIG. 15 (a) is the eco mode (energy saving mode), and even if it is slow, the reach distance does not change and the fuel consumption is emphasized (in other words, the air conditioner reaches the set temperature, but it is a little more than the normal mode) take time). And if it operate | moves like Fig.15 (a), compared with the operation | movement of Fig.14 (a), a maximum demand value can be suppressed, As a result, an electricity bill can be reduced significantly. The method (technology, structure, step, etc.) of this embodiment for suppressing the maximum demand value functions well in the operation under the restriction of the power suppression instruction data (323) required in the demand response 300, In other words, even under conditions where the output is suppressed more than usual (when there is no demand response) due to power suppression, comfort is lost without consuming excessive power (specifically, saving more than usual). Air conditioning (air conditioner) can be used without

  FIG. 16A shows the ventilation / air conditioning operation when the customer attraction rate (average operating rate) is 100% in the energy saving system 100 of the present embodiment. On the other hand, FIG. 16 (b) shows the ventilation / air conditioning operation when the customer attraction rate (average operating rate) is 20% in the energy saving system 100 of the present embodiment.

  As shown in FIG. 16A, when the customer collection rate (average operating rate) is 100% (that is, operating rate data or store congestion level data is 100%), the ventilation fan 62 is operated at a ventilation rate of 100%. And the rotation speed (inverter frequency) of the inverter motor 24 which moves the refrigerant | coolant which passes the indoor air conditioner 60 is adjusted corresponding to the ventilation ratio 100%.

  On the other hand, as shown in FIG. 16B, when the customer collection rate (average occupancy rate) is 20% (that is, the occupancy rate data or the store congestion level data is 20%), the ventilation fan 62 operates at a ventilation rate of 20%. Let And the rotation speed (inverter frequency) of the inverter motor 24 which moves the refrigerant | coolant which passes the indoor air conditioner 60 is adjusted corresponding to the ventilation ratio 20%. It should be noted that the rate of attracting customers (average occupancy rate, occupancy rate data, store congestion level data) and the ventilation ratio do not necessarily have to coincide with each other as long as they are related to each other. And the value of a ventilation ratio can be determined based not only on the rate of attracting customers but also on the amount of smoking, the amount of smoke and odor.

  By using the power management apparatus 100 of the present embodiment, it is possible to set an appropriate ventilation ratio / inverter frequency according to the customer collection rate (average operating rate), and as a result, it is possible to achieve electricity saving. Here, when the customer attraction rate (average operating rate) as shown in FIG. 16B is 20%, only the set temperature of the air conditioner is concerned, and the ventilation fan 62 is operated with the ventilation ratio being 100%. If this happens, a large amount of air cooled by the air conditioner will be thrown out of the store 50 and taken in outside air (hot air in midsummer), so it will be necessary to operate the air conditioner fully. . On the other hand, if the power management apparatus 100 of this embodiment is used, an appropriate ventilation ratio and inverter frequency are set according to the rate of attracting customers (average operating rate), so energy is saved in a comfortable air-conditioning environment (power saving and electricity cost control) ) Can be performed.

  On the other hand, if only the electricity cost savings are concerned and the set temperature of the air conditioner is raised when the customer attraction rate (average operation rate) as shown in FIG. It will be far from, and will adversely affect customer acquisition and sales. In addition, when the rate of attracting customers (average occupancy rate) as shown in FIG. 16 (a) is 100%, if the ventilation ratio is set to a state like 20%, cigarette smoke remains full ( If the place is serving food, the smell of the food will remain full) and it will be far from a comfortable store environment, which will also adversely affect customer acquisition and sales. And if the power management apparatus 100 of this embodiment is used, since an appropriate ventilation ratio and inverter frequency can be set according to the rate of attracting customers (average operating rate), significant power saving is achieved while realizing a comfortable environment. The effect can be achieved.

  Next, with reference to FIG. 17 and FIG. 18 as well, the effect of saving the air-conditioning electricity cost by the power management apparatus (energy saving system) 100 of this embodiment will be described. FIG. 17 is a graph with the month of one year on the horizontal axis and the maximum demand value (kw) on the vertical axis. FIG. 18 is an equation showing that the electricity charge is the sum of the basic charge and the power charge.

  In the store 50, the electric charge of the air conditioner (air conditioner) has the most influence on the electricity bill, and 90% of the electric charge of the air conditioner (air conditioner) is related to the inverter motor 24. In order to reduce the electricity bill of the store 50, usually, the usage amount of the air conditioner (air conditioner) is reduced or the set temperature is increased if it is cooled (lower if it is heated). Is called. However, the maximum demand value is an important factor that affects electricity prices. The high-voltage power meter calculates the average value of power every 30 minutes, which is called the demand value, and the maximum demand value (maximum demand value) in one month is the contract power for the next year. .

  Therefore, in the usage state of the graph shown in FIG. 17, since the maximum demand value in August on the left is 150 kW (D1 points), the contract power is 150 kW. However, since the maximum demand value in August on the right is 160 kW (D2 points), the contract power for one year will be 160 kW. That is, as shown in FIG. 14, the basic charge is determined by the product of the contract power (maximum demand value for the past year) and the unit price of the charge, and the power charge (power used in one month) is added to the basic charge. The amount will be the electricity bill for the month.

  Therefore, in the usage state shown in FIG. 18, it is important that the basic charge (contract power based on the maximum demand value) is not 160 kW (it is important to keep it at 150 kW). Focusing on reducing (electricity used in a month) could limit the effect of reducing electricity charges. Then, to suppress the maximum demand value forcibly, if a power increase curve is detected such that the maximum demand value exceeds a set value (for example, 150 kW), an air conditioner (or other electric device (such as a refrigerator)) is detected. ) Is forcibly turned off, the air conditioner (air conditioner) stops in midsummer, resulting in an uncomfortable store 50 or a malfunction of another electrical device (for example, stoppage of the refrigerator) Etc. are not preferable.

  In the power management apparatus (energy saving system) 100 according to the present embodiment, the following method is applied by controlling the maximum demand value, and a large electricity saving is achieved while being a comfortable air-conditioned space. The maximum demand value control method can also be applied to control satisfying the demand response condition.

  That is, first, it takes a little time as shown in FIG. 15 (c), unlike the method of fully operating the air conditioner so as to reach the set temperature (99) in the shortest time as shown in FIG. 14 (c). However, the inverter motor 24 is controlled so that the inverter frequency is slightly lowered and the set temperature (99) is maintained. Thereby, it can suppress that the maximum demand value becomes large. And by suppressing the maximum demand value, the basic contract can be revised to a lower one, and in one example, the electricity bill can be reduced by 30%.

  Next, by determining the ventilation rate (operation of the ventilation equipment) according to the customer acquisition rate (average operation rate or operation rate data, store congestion level data), clean air-conditioned air that has low customer acquisition rate and is not contaminated Can be prevented from being thrown away to the outside when the air is in the store 50. Thereby, it is possible to obtain the effect of suppressing the maximum demand value and the effect of lowering the electricity charge (electric power used in one month).

  Furthermore, by adjusting the inverter frequency according to the rate of attracting customers (average occupancy rate, occupancy rate data, store congestion level data), the ventilation ratio is small and a lot of air-conditioned air remains in the store 50 Forcibly, the inverter motor 24 can be prevented from operating at the inverter frequency corresponding to the set temperature. That is, when the ventilation ratio is low, by reducing the rotation speed of the inverter motor 24 accordingly, the effect of suppressing the maximum demand value and the effect of lowering the electricity charge (electric power used in one month) are obtained. be able to.

In addition, it is possible to perform air-conditioning and ventilation control with zone control as shown in FIG. 1 8. Thereby, the effect of suppressing the maximum demand value by performing partial air conditioning / ventilation control without changing the air conditioning set temperature of the entire store 50 (or without changing the ventilation ratio of the entire store 50). And, the effect of lowering the electricity charge (electric power used in one month) can be obtained.

  If the method described above is used, the store 50 equipped with the power management apparatus (energy saving system) 100 of the present embodiment achieves the effect of saving about 1 to several million yen in electricity bill per year. Can do. Further, it is possible to easily respond to a power suppression command (transmission of power suppression instruction data) from the aggregator 96 in the demand response 300. Furthermore, in the configuration of the present embodiment, the inverter frequency adjustment system 30 can be retrofitted to the existing air conditioning equipment device 20 so that the air conditioning equipment device 20 corresponding to the demand response 300 can be used. This is very advantageous in terms of equipment construction and cost.

  Next, in the power management apparatus 100 of this embodiment, control of the ventilation ratio by zone control will be described with reference to FIGS. 19 and 20. In addition, since the air-conditioning control by zone control is demonstrated in FIG.11 and FIG.12, it can understand together with it.

  The store 50 shown in FIG. 19 is a pachinko store (pachinko hall). Here, the store 50 is divided into the area 1 to the area 4, and the ventilation areas of the zones 1 to 4 are allocated correspondingly. The ventilation fans 62 in each zone (zones 1 to 4) are connected to a duct 66, and intake air 71 and exhaust air 72 are performed at the ends of the duct 66 (external air intake / exhaust ports). The ventilation fan 62 is controlled by the ventilation amount adjustment system 70, and the ventilation amount adjustment system 70 operates according to commands from the hall computer device 55 and the touch panel 75.

  In this example, the operating rate of area 1 (1 to 100s) is 40%, and the corresponding ventilation amount of zone 1 (1 to 100s) is 40% of the assumed maximum value (ventilation ratio 40%). . And the operation rate of area 2 (101-200 series) is 70%, and the ventilation volume of the zone 2 corresponding to it is 70% of the assumed maximum value (ventilation ratio 70%). Moreover, the operation rate of the area 3 (201-300 series) is 30%, and the ventilation volume of the zone 3 corresponding to it is 30% of an assumed maximum value (ventilation ratio 30%). The operation rate of area 4 (301 to 400 series) is 60%, and the ventilation amount of zone 4 corresponding to it is 60% of the assumed maximum value (ventilation ratio 60%).

  In the case of the pachinko store 50, since the player (customer) moves with time, it is adjusted to each zone according to real time (or every predetermined time) rather than setting a fixed ventilation ratio in each zone. It is preferable to control the ventilation operation by the ventilation fan 62 by calculating the ventilation ratio.

  FIG. 20 shows a display screen 55 a of the hall computer device 55. In the hall computer device 55, pachinko operating rate software 80 is operating, and operating rate data is displayed on the display screen 55a. The operation is 200 units, the non-operation is 200 units, and the average operation rate is 50%, but the operation rate of each area (each zone) is also counted here, so the ventilation operation according to the operation rate If this is executed, the ventilation / air conditioning operation can be executed efficiently. That is, it is possible to perform ventilation / air conditioning operations with an average operating rate of 50%, but it is possible to obtain a power saving effect without waste by performing ventilation / air conditioning operations with zone control. Since power can be saved without waste, it is possible to more reliably obtain the effect of suppressing the maximum demand value and the effect of lowering the electric energy charge (power used in one month).

  In the above-described embodiment, the electricity cost saving effect based on the structure or function of the power management apparatus (energy saving system) 100 has been described. However, in order to obtain the electricity cost saving effect, it is preferable to prevent human error. The most important point in human error is that the energy-saving method (power management method) according to this embodiment is ignored (ignoring the manual), and the staff changes the air-conditioning set temperature without permission (if cooling) Lower the set temperature).

  In the example shown in FIG. 15 (c), when the power management apparatus 100 of the present embodiment is used, the set temperature is properly reached at 10:30 am, but because it is hot in midsummer, There is a possibility that some people will change the set temperature of the air conditioner to a very low temperature (for example, 17 ° C.) without permission. The power management apparatus 100 according to the present embodiment is intended to exhibit a remarkable electricity cost saving effect when the temperature is set to a set temperature (for example, 26 ° C.). Inverter frequency control in accordance with temperature is activated, and as a result, the maximum demand value may exceed that of contract power. Then, the effect of suppressing the electricity bill cannot be obtained. This leads to an operation for canceling the command of the demand response 300, which is not preferable.

  Of course, the staff is not bad, but it is done to avoid the heat of midsummer, so if you are in the morning for a short time you may think that it is safe to ignore manuals / rules, the maximum demand value May not be aware that is linked to contract power. And the staff (or the team including the boss) may return the set temperature to the manual rule at the time when the manager comes (for example, 10:00 am), so why can't the electricity cost be suppressed? It may take time to investigate the cause.

  FIG. 21 is a block diagram for explaining a modification example of the power management apparatus 100 of the present embodiment. The power management apparatus 100 shown in FIG. 21 is basically the same as that shown in FIG. However, a signal transmission device 39 for transmitting information from the inverter frequency adjustment system 30 to the communication network (Internet) 90 is provided.

  The signal transmission device 39 of the present embodiment is, for example, a mobile phone (or PHS) for information data communication. In the present embodiment, a 3G (third generation) mobile phone (a phone that can not make a call but distributes information) is used as the signal transmission device 39. The signal transmission device 39 is not limited to a mobile phone, and may be another device (for example, a computer device or a wireless device), and the wiring 105 connected to the Internet 90 may be wireless or wired. Absent.

  In the illustrated configuration example, the signal transmission device 39 is connected to the hall computer device 55 (see the wiring 103). In addition, the hall computer device 55 is connected to the ventilation adjustment system 70 by a wiring 102. In addition, the hall computer device 55 is connected to the Internet 90 via the Internet connection router 51 and the wiring 101. Here, the wirings 101, 102, and 103 may be wired or wireless.

  In the system (power management device) 100 shown in FIG. 21, the signal transmission device 39 sets the set temperature of the air conditioner device 20 (or the indoor air conditioner 60) from the hall computer device 55 (or the inverter frequency adjustment system 30). It is configured so that it can be obtained and automatically transmitted to the Internet 90. In addition to the air conditioning set temperature, the signal transmission device 39 can transmit, for example, data (air conditioning data) such as a real-time demand value, operating rate data (or store congestion level data), ventilation ratio, and store temperature. . As a result, the staff can know that the air-conditioner set temperature is changed without permission, and as a result, it is possible to prevent the maximum demand value from increasing (the electricity bill from increasing).

  Further, the setting temperature change check may be performed by the information terminal 16 connected to the Internet 90 without being checked by the hall computer device 55. The configuration example shown in FIG. 21 shows a state in which at least one information terminal 16 (16A, 16B) is connected to the Internet 90. The information terminal 16 is a mobile information communication terminal (for example, a smart phone, a tablet, or a notebook PC) in addition to a desktop computer that can be connected to the Internet 90. The mobile information communication terminal 16 is convenient because it can be confirmed anywhere at any time. Further, since it is not necessary to use one specified information terminal 16, for example, a plurality of people such as a pachinko store owner, a pachinko store manager, and a system manager may simultaneously check the set temperature change (or demand value). Or the setting information / modification information of the demand upper limit value).

  In the present embodiment, the information terminal 16 is a smartphone (for example, an iPhone (registered trademark) manufactured by Apple, a smartphone equipped with an Android OS (various Android smartphones)) as shown in FIG. A smartphone is a multi-function mobile phone, and has a call function and an Internet communication function, and can manage, process, and transmit information as well as the call function. However, if it is possible to check the set temperature change (or check the demand value), it is not limited to a smartphone, and any mobile phone (for example, a so-called feature phone) can be used for information communication. Alternatively, a terminal such as a personal computer (for example, a desktop PC), a game machine, or a television may be used. Moreover, as a portable communication device (information communication terminal) that can be carried, a tablet computer, a notebook computer, and a wearable computer can be used in addition to a smartphone and a mobile phone.

  FIG. 22 shows an information communication terminal (smartphone) 16 (200) according to the present embodiment. The illustrated smartphone 200 includes a housing 210, an image display unit (display unit) 220, and buttons (main buttons) 230. A switch button 211 is provided on the side surface of the housing 210. The display unit 220 is a touch panel display (liquid crystal display or organic EL display).

  The smartphone 200 can operate a specific program (application), and 260 of the application (sometimes referred to as “application”) is displayed on the display unit 220. An application can be operated by touching an icon (such as 260) on the display unit 220. The set temperature change check application (smart phone application program) in the present embodiment is downloaded through the Internet line and installed in the smartphone 200, and is displayed as the application icon 250 of the present embodiment. When the application icon 250 is pressed, a preset temperature change check application is started, and a preset temperature change check (and / or a demand value check in real time or at a predetermined time) can be performed there. Depending on the configuration of the application, the set temperature of the air conditioner device 20 in the store 50 may be changed by remote control. If such a remote control function is introduced, the maximum demand value will increase even if the checker (administrator) is far away and it takes time to change the air conditioning temperature setting (the electricity charge will be increased). Can be prevented or suppressed. Similar processing may be executed by the management server 15 in the management company 10.

  In the energy saving system 100 of the present embodiment, an example in which arithmetic processing operations and / or control operations are performed mainly on the control circuit board (35) of the inverter frequency adjustment system 30 and the control circuit board of the ventilation volume adjustment system 70 will be described. However, the present invention is not limited to this, and it is also possible to execute these arithmetic processing operations and / or control operations programmatically (in software).

  For example, in the power management apparatus 100 that controls both the air conditioning equipment and the ventilation equipment, a system cooperative control device that cooperates and controls the ventilation ratio and the inverter frequency adjustment is constructed in software. Can be constructed with a structure as shown in FIG. 23 (particularly, a semiconductor circuit structure). The system cooperative control device 150 shown in FIG. 23 includes a central processing unit 160 that calculates data and a storage device 170. The system cooperative control device 150 may use a central processing unit (160) and a storage device (170) in the hall computer device 55, or a general-purpose computer device (personal computer device, server device, tablet computer device ( Alternatively, the central processing unit (160) and the storage device (170) in the smartphone device)) may be used.

  The system cooperation control device 150 includes an input unit 151 connected to the wiring (wired or wireless) 105 and an output unit 152 connected to the wiring (wired or wireless) 107. The input unit 151 and the output unit 152 may be common. Further, the wiring 105 and the wiring 107 may be common, or both the wiring 105 and the wiring 107 may be wireless (for example, WiFi, wireless LAN, mobile phone radio wave, etc.). The storage device 170 of the system cooperation control device 150 stores a power management program (or an air conditioning electricity saving program, an energy saving program) 180. The power management program 180 may be configured to be downloadable via the wiring 105 (or may be downloaded from the server device 15 in FIG. 4 via the Internet 90).

In the configuration of the present embodiment, when the power management program 180 of the system cooperation control device 150 is activated, the central processing unit 160 and the storage device 170 operate in cooperation, whereby the system cooperation control device 150 performs the following. Functions are realized: (4a) Function for reading store congestion level data (161); (4b) Function for calculating ventilation ratio from store congestion level data (162); (4c) At least of store congestion level data and ventilation ratio A function for calculating the control frequency of the inverter motor 24 from one side (163); (4d) a function for transmitting at least one of the ventilation ratio and the control frequency of the inverter motor 24 (164).
Note that the power management program 180 is not limited to being stored in the storage device 170, but is stored in a storage device in another location (for example, a cloud memory on the Internet), and the program is started there, You may make it implement | achieve the function (161-164) of the system cooperation control apparatus 150. FIG.

The following data information is stored in the storage device 170 for processing execution and data storage of the functions (161 to 164) of the system cooperative control device 150: (5a) Store congestion level data (171) ( 5b) Ventilation ratio data (172) (5c) Inverter motor 24 control frequency data (173) (5d) Air conditioning setting data (air conditioning set temperature, air conditioning set time, demand value information, store zone information, individual air conditioning indoor unit information , Individual air conditioner outdoor unit information, individual ventilator information, etc.) (174).
In this embodiment, the data (171 to 174) is stored in the storage device 170 of the system cooperation control device 150. However, the data (171 to 174) may be stored in another storage device (for example, a cloud memory on the Internet). I do not care.

  Data including the ventilation ratio generated by the functions (161 to 164) realized by the system cooperative control device 150 and the control frequency of the inverter motor 24 is transmitted through the output unit 152. Then, the ventilation volume adjustment system 70 receives the ventilation ratio data, and can then execute control based on the ventilation ratio. On the other hand, the inverter frequency adjusting system 30 can receive the control frequency of the inverter motor 24 and then perform control based on the control frequency.

  Executing this arithmetic processing operation and / or control operation programmatically (in software) can also be performed by the ventilation volume adjustment system 70 and / or the inverter frequency adjustment system 30 described above.

  For example, the ventilation amount adjustment system 70 includes a central processing unit 160 and a storage device 170 as shown in FIG. 23, and the central processing unit 160 and the storage device are activated by starting the ventilation amount adjustment program (180). The function of the ventilation volume adjustment system 70 can be realized by the 170 operating in cooperation. Such functions include, for example, (1a) a function of reading operation rate data from the hall computer device 55; (1b) a function of calculating a ventilation ratio from the operation rate data; and (1c) a ventilation device based on the ventilation ratio. And a function of controlling the device 61. Of course, in actual application, various modifications can be made according to environmental conditions and setting conditions. Then, the process data and operation result data associated therewith can be stored in the storage device 170.

The inverter frequency adjustment system 30 includes the central processing unit 160 and the storage device 170 as shown in FIG. 23, and the central processing unit 160 and the storage device are started by starting the inverter frequency adjustment program (180). The functions of the inverter frequency adjustment system 30 can be realized by the operation of 170 in cooperation.
Such functions include, for example, (2a) a function of reading a ventilation ratio from the ventilation amount adjustment system 70; (2b) a function of calculating a control frequency of the inverter motor 24 in the air conditioning equipment device 20 from the read ventilation ratio; (2c) a function of controlling the inverter motor 24 based on the calculated control frequency. Of course, in actual application, various modifications can be made according to environmental conditions and setting conditions. Then, the process data and operation result data associated therewith can be stored in the storage device 170.

  In addition, in the power management apparatus 100 shown in FIG. 21, the power management program (180) (6a) a function for comparing the air conditioning temperature set value during operation and the input air conditioning temperature setting; (6b) a comparison determination It may have a configuration that realizes a function of transmitting data. Such a function can be realized by a computer device in the store 50 (for example, 55, 39).

  Next, FIG. 24 is a flowchart illustrating an example of a usage method (operation method) of the power management apparatus 100 having the configuration illustrated in FIG.

  First, a demand response instruction is transmitted in the demand response 300 via the communication network 90 (step S400), and the power management apparatus 100 (particularly, the inverter frequency adjustment system 30) of the present embodiment receives the demand response instruction. Note that another apparatus such as the hall computer apparatus 55 may be configured to transmit the demand response instruction to the inverter frequency adjustment system 30 after receiving the demand response instruction.

  Next, a store congestion level in the store 50 is set (step S410). In the hall computer device 55 (or the computer device in which the system cooperation control device is realized) as shown in FIG. 20, the operation rate is set to the store congestion level. The store congestion level may be set to use a value adjusted according to factors such as smoking cessation and smoking in addition to the case where the value of the operation rate is used as it is.

  Next, the store congestion level is input (step S415). In the example shown in FIGS. 19 and 20, the operation rate (store congestion level) is 40%, 70%, 30, 60%, and this value is input. The store congestion level may be input automatically by a computer device (55) or by a person. In addition, although it is preferable to use real-time numerical values and data for the store congestion level, an average value or a predicted value can also be input.

  Next, the system cooperation control device 55 (150) calculates the ventilation ratio from the store congestion level (step S420). The calculation of the ventilation ratio may be executed by the ventilation amount adjustment system 70 as described above. Then, the system cooperation control device 55 (150) calculates the control frequency of the inverter motor 24 (step S430). The calculation of the control frequency may be performed by the inverter frequency adjustment system 30 as described above. Further, as described above, in the control frequency calculation step, the calculation is executed in consideration of the restriction of the demand response instruction (power suppression instruction data).

  Thereafter, the inverter motor 24 is controlled by the inverter frequency adjusting system 30 based on the calculated control frequency (step S440). On the other hand, based on the calculated ventilation ratio, the ventilation device 61 (ventilation fan 62) is controlled by the ventilation amount adjustment system 70 (step S450). Here, the control of the inverter motor 24 is energy saving based on the store congestion level (or ventilation ratio), and as shown in FIG. 19, the inverter is operated at full operation so as not to increase the maximum demand value. The control is performed such that the inverter motor 24 is rotated slightly more slowly than the motor 24 is rotated. The control of the inverter motor 24 is such that the inverter motor 24 is rotated within the range of the condition (constraint) of the demand response instruction (power suppression instruction data).

  Subsequently, a process of transmitting various system data is performed (step S460). The system data here is, for example, manual (or set initial value) air conditioning set temperature, operating air conditioning set temperature, coincidence / inconsistency judgment data between the initial setting and operating air conditioning set temperature, real time Information such as demand value, in-store temperature, and room temperature. In the configuration of the present embodiment, the system data is constantly transmitted to the Internet 90 by the signal transmission device 39. The system data may be transmitted from the hall computer device 55 to the Internet 90.

  The data transmitted in step S460 can be viewed on the information terminal 16 (for example, the smartphone 200) via the Internet 90. Similarly, it can be confirmed by a device of the management company 10 (for example, the server device 15). By looking at the system data, if an abnormality in the air conditioning set temperature during operation or an abnormal demand value (unexpected numerical value) occurs, it is possible to deal with it immediately. Such error prevention (especially operation mistakes, human errors) also ensures the energy saving effect (a remarkable effect of suppressing electricity costs).

  Next, FIG. 25 is a flowchart illustrating an example of another usage method (operation method) of the power management apparatus (energy saving system) 100 according to the present embodiment. The method shown in FIG. 25 is a flowchart that focuses on the most important demand value for electricity bill suppression and prevention of an arbitrary change in the air conditioning set temperature.

  First, the air conditioning temperature is set in the store 50 (step S500). The air conditioning temperature setting here may be set to a more comfortable air conditioning setting temperature in anticipation that the electricity bill can be reduced by the method of this embodiment, or a little comfort to maximize the reduction of the electricity bill. The air conditioning temperature may be set in accordance with the dropped response. In addition, when a plurality of air conditioner devices 20 are installed in the store 50, the air conditioning temperature may be set individually for each air conditioner device 20.

  Next, a demand response instruction (power suppression instruction data) is received from the aggregator 96 (step S510). Note that either the demand response instruction reception (S510) or the air conditioning temperature setting (S500) may be performed first or simultaneously. Note that the demand response instruction is basically transmitted before the demand response is executed, but the power of the present embodiment can be performed in real time in accordance with the reception of the demand response. The management apparatus 100 may be constructed.

  Next, the control rotation speed of the inverter motor 24 is calculated based on the condition of the demand response instruction (power suppression instruction data) (step S520). Here, as shown in FIG. 15, the calculated control rotation speed is a numerical value that turns the inverter motor 24 slightly slowly rather than turning the inverter motor 24 at full operation so that the maximum demand value does not increase. calculate. Thereby, it can suppress that the maximum demand value becomes large too much. The calculated control rotational speed is not limited to a fixed value, and may be a numerical value that varies depending on time (or in-store temperature).

  Next, the inverter motor 24 is controlled based on the calculated control rotational speed (step S525). Here, in the configuration of the present embodiment, since the inverter motor 24 is controlled so that the maximum demand value does not increase, it is possible to prevent the contract power from jumping up.

  Then, along with the control (operation execution) of the inverter motor 24, the demand value of the air conditioning equipment (or the measurement of the demand value of the entire store 50) is measured (step S530). By measuring the demand value of the inverter motor 24 or the store 50 in real time (in addition to actual continuous real time, real time at intervals of 1 minute, 10 minutes, 15 minutes, 30 minutes, etc.) It is possible to suppress the maximum demand value from increasing.

  In addition, the air conditioning temperature set value is acquired together with the demand value measurement (step S540). Here, the air conditioning temperature setting value is acquired because the staff of the store 50 may change the air conditioning temperature setting value without permission. If the set value of the air conditioning temperature is changed, the inverter motor 24 is controlled accordingly, and thus the possibility that the maximum demand value becomes large cannot be excluded. In order to prevent such a situation, the air conditioning temperature set value is acquired as appropriate (or always) to achieve the expected air conditioning schedule and electricity cost reduction.

  Next, the air conditioning temperature set value acquired in step S540 is wirelessly transmitted (step S550). In the configuration of the present embodiment, data transmission is performed by a signal transmission device 39 that transmits information to the Internet 90. Note that data transmission by wire is also possible. In this case, the data of the air conditioning temperature setting value may be lost due to a failure such as turning off the power of the computer device that has the information (air conditioning temperature setting value) or no connection to the Internet. It may not be uploaded. Since the data transmission here is mainly based on the air conditioning temperature setting value, the amount of data is small, so even if the data is always transmitted wirelessly to the Internet 90, the communication fee is low. Therefore, there are few burdens even if it is always radio transmission, and the merit of constant monitoring is greater.

  And the data transmitted by step S550 are received with the smart phone 16 (200), and are displayed with the smart phone 16 (step S560). By displaying the air conditioning temperature setting value data in real time (or the discrepancy data (or discrimination data) between the setting and the air conditioning temperature setting at the time of operation), the maximum demand value is prevented from increasing due to human error. As a result, the electricity cost reduction as expected can be achieved.

  In addition, the specific detailed structure / operation of the product level of the air conditioning equipment 20 including the inverter motor 24, the specific detailed structure / operation of the product level of the ventilation fan 62 including the ventilation fan 62, the control circuit / server apparatus or the Internet. The technical data transmission / reception program, the interface program with the input / output device, the error message program, and the like are not the main items of the embodiment of the present invention, and are omitted for the purpose of simplifying the understanding of the technical contents. These technologies can be configured, implemented / operated (implemented) based on common technical knowledge in the air conditioning / ventilation technical field, control circuit technical field, or information communication technical field. Similarly, a data processing program, a data transmission / reception program, a call / communication technology, an Internet-related technology, and an application operation technology in an information communication terminal (for example, a smartphone) are also omitted for the purpose of simplifying the understanding of the technical contents. These technologies can be implemented / operated (implemented) based on common technical knowledge in the technical field of information communication terminals (smartphones). In addition, the function described above is mainly a function name viewed from one device, that is, “transmission” and “reception” are a pair of terms, so in the function viewed from the other device, It is noted that the name of the term changes.

  As described above, according to the configuration of the embodiment of the present invention, in the power management method under the condition that the power suppression instruction (323) by the demand response 300 is performed, the power suppression instruction data (323) by the demand response 300 is provided. ) (S100), acquiring the air conditioning set temperature (S200), calculating the control frequency of the inverter motor 24 based on the power suppression instruction data and the air conditioning set temperature (S300), A step of controlling the air conditioner device 20 by the inverter frequency adjustment system 30 based on the control frequency is executed. In the step of calculating the control frequency of the inverter motor (S300), the rotation that reaches the air conditioning set temperature in a time later than the fastest arrival control frequency that is the control frequency that reaches the air conditioning set temperature in the shortest time as the control frequency. The number is calculated (see FIG. 15C).

  Moreover, the demand value at the time of operation | movement in the air conditioner apparatus 20 is measured by the inverter frequency adjustment system 30, and the inverter frequency adjustment system 30 is the air conditioner apparatus apparatus in the state installed in the shop 50 via the control frequency adapter 22. 20 can be connected. Therefore, the power management apparatus 100 (particularly, the inverter frequency adjustment system 30) of the present embodiment can easily make the existing air conditioner apparatus 20 compatible with the demand response 300. Also, according to the power management apparatus (method) 100 of the present embodiment, even if there is a demand response 300 command, it is possible to suppress the inefficiency of the air conditioner. Since the electricity bill can be further suppressed by combining the effects of the response 300, the demand response 300 can be introduced with confidence. Therefore, the power management apparatus (method) 100 according to the present embodiment contributes to the spread of the demand response 300.

  More specifically, according to the method of the present embodiment, the power consumption of the store 50 (customer 95) can be suppressed by the power suppression by the demand response 300, and there is an instruction to suppress the power of the demand response 300. Even in the case where the effectiveness of air conditioning by the air conditioning equipment device 20 is deteriorated, “in the process of calculating the control frequency of the inverter motor, the fastest arrival that is the control frequency that reaches the air conditioning set temperature in the shortest time as the control frequency. Since the rotation speed that reaches the air conditioning set temperature is calculated at a time later than the control frequency, the time to reach the set temperature is delayed, but the effectiveness of the air conditioning does not deteriorate, so that it does not feel uncomfortable. Can ensure comfort and, at the same time, suppress the maximum demand value, resulting in electricity charges It can be reduced significantly. In other words, according to the present embodiment, even in the situation where the power suppression instruction of the demand response 300 is given and the effectiveness of the air conditioning becomes worse, it is possible to eliminate the poor effectiveness of the air conditioning and not to feel uncomfortable. At the same time, it is possible to control the maximum demand value, and thus it is possible to achieve a significant saving in electricity costs while being a comfortable air-conditioned space.

  In the configuration of the present embodiment, the inverter frequency adjustment system 30 is connected to the air-conditioning outdoor unit 29 via the control frequency adapter 22, and the air-conditioning equipment device 20 is installed in the store 50. The inverter frequency adjustment system 30 has a configuration that can be connected to the air conditioning equipment device 20 installed in the store 50. Therefore, it is possible to attach to an already installed air conditioner device without introducing a new air conditioner device, that is, using an existing air conditioner device (new air conditioner). Conveniently, the power response of the demand response 300 can be executed (without replacing the device), and the electricity price can be reduced by controlling the maximum demand value.

  In addition, in this embodiment, when not only the control of the air conditioner device 20 but also the control linked to the ventilator device 61 is performed, the electricity bill can be further reduced. Specifically, the ventilation volume adjustment system 70 connected to the ventilation device 61 includes a function of calculating the ventilation ratio from the operation rate data and a function of controlling the ventilation device 70 based on the ventilation ratio. The inverter frequency adjustment system 30 connected to the air conditioner device 20 including the inverter motor 24 calculates the control frequency of the inverter motor 24 from the ventilation ratio, and the function of controlling the inverter motor 24 based on the control frequency. , The ventilation ratio and the control frequency of the inverter motor 24 can be controlled in conjunction with the operating rate of the store 50. As a result, power consumption in the store 50 (such as a pachinko store or a card dealer store) can be saved.

  More specifically, in stores such as pachinko parlors, it is necessary to actively ventilate cigarette smoke. However, if the ventilating fan is fully rotated even though the store 50 is not so crowded (ie, If the ventilation ratio is increased), the air that has been cooled down (the warmed air in winter) will be thrown out. According to the present invention, the ventilation rate is calculated from the operation rate data of the store, and the control frequency of the inverter motor (that is, the operation of the air conditioner device) can be controlled in conjunction with the ventilation rate. When there are few customers inside, wasteful air (cooled air) can be reduced from being wasted. As a result, it is possible to perform optimal air conditioning and ventilation according to the crowded situation of the actual store 50, and more conspicuous than energy saving using inverter functions and demand control of high-level technology as much as possible at present. An energy saving effect can be achieved, and therefore the electricity bill of the store 50 can be significantly reduced.

  As mentioned above, although this invention was demonstrated by suitable embodiment, such description is not a limitation matter and of course various modifications are possible. In particular, in the above-described embodiment, the pachinko store has been mainly described as the store 50, but it can be suitably applied to other stores (car dealers, book stores, coffee shops, restaurants, casino stores, rental videos, drug stores). Is. In this case, the hall computer device 55 is installed with a software system suitable for the store. In addition, the power management system (energy-saving system in demand response) 100 according to the present embodiment includes, for example, a plurality of effective features, and each of them has a sufficient technical effect. Active use of such single features is also of high technical value. In particular, in the description of the present embodiment, many examples in which air conditioning control and ventilation control are used in combination have been described. However, the power management apparatus 100 that combines demand response and air conditioning control also has a sufficient technical effect. The features described above can be applied to each other as long as they do not contradict each other. Furthermore, the features on the system / device can be combined with the features of the process (or program). Or, the features on the program) can be combined with the system / device. In addition, although the entire system 100 of the present embodiment has been described, the program 180 alone (or the application 250 to be introduced into the smartphone 200) according to the present embodiment, specifically, the program itself or the program is stored. It is also possible to commercialize recorded recording media and downloadable program products as intellectual property.

  As one modified example of the present embodiment, a configuration as shown in FIG. 26 can be given. The power management 100 shown in FIG. 26 is basically the same as that shown in FIG. 5, but has a configuration in which a power meter (power meter) 81 of the store 50 is connected to the inverter frequency adjustment system 30. Yes. In this example, the power meter 81 is connected to the frequency adjustment system 30 via the wiring 83. The wiring 83 is a telephone line, a wired line (LAN line), or the like, but may be a wireless line. By connecting the power meter 81 to the inverter frequency adjustment system 30, when the target contract power is approached, the inverter frequency adjustment system 30 controls the rotation speed (inverter frequency) of the inverter motor 24 to increase the contract power. A function can be added so as not to stutter. This control (that is, control for executing a function to prevent the contract power from increasing) is performed manually or automatically while monitoring the power consumption of the power meter by the remote monitoring device 15 (or the information terminal 16 in FIG. 21). It is also possible to do this.

  In addition, in the energy saving system 100 shown in FIG. 26, a thermometer that measures the temperature of air in the store 50 separately from a thermometer for setting the temperature of the air conditioner (or a temperature sensor incorporated in the indoor unit 60). A (temperature sensor) 89 is provided. This thermometer 89 is connected to the energy saving system 100 of the present embodiment by wire (or wirelessly), and is not the temperature detected by the temperature sensor of the indoor unit 60 (or the air conditioner device 20) (or in combination with it). More appropriate air conditioning can be executed in accordance with the actual air temperature in the store. The thermometer 89 is not limited to one, and a plurality of thermometers 89 can be arranged. For example, the thermometer 89 can be provided in each region (50a to 50f) shown in FIG. Since the customer or staff in the store 50 feels heat / coldness not by the temperature detected by the temperature sensor of the air conditioner device 20, but by the actual air temperature in the store, such actual air temperature is detected. Incorporating the information from the temperature sensor 89 into the energy saving system 100 leads to more comfortable control of the air conditioning.

  In addition, as a setting (user setting) performed by a user who uses the energy saving system 100 (for example, the staff of the store 50 or the staff of the management company), the setting of the indoor temperature of the air conditioner device 20 and the inverter motor 24 There is a setting for the upper frequency limit. The room temperature of the air conditioner apparatus 20 is normally set by a remote controller (air conditioner remote controller) of the indoor unit 60, but may be set by the energy saving system 100 of the present embodiment. Moreover, you may provide the function which takes in the preset temperature of the remote control of the indoor unit 60 in the energy saving system 100 (or inverter frequency adjustment system 30). The setting of the upper limit value of the frequency of the inverter motor 24 is one of important settings for saving power by preventing the inverter motor 24 from rotating excessively. Even if the upper limit value is set to 70%, for example, if the user (for example, the staff of the store 50) changes the setting to 100% without permission, the contract power increases. In order to prevent this, the signal transmission device 39 shown in FIG. 21 can transmit information on the upper limit value of the frequency of the inverter 24 (or a signal that the setting has been changed), and the contract power It is possible to prevent the rising. This function can be executed by transmission from the hall computer device (system cooperative control device) 55 in the energy saving system 100 to the Internet 90 in addition to communication by the signal transmission device 39. In addition, in the flowchart shown in FIG. 25, the acquisition of the air conditioning temperature set value has been mainly described. However, instead of the air conditioning temperature setting value, the acquisition of the frequency upper limit value of the inverter motor 24 is mainly performed (or the air conditioning temperature). The flowchart may be executed (both with the set value and the frequency upper limit value of the inverter motor 24). Although described above by way of example, such modifications can be performed.

  According to the present invention, there is provided a power management method and a power management apparatus that save power consumption while performing air conditioning control that does not feel uncomfortable even if the operation (output) of the air conditioning equipment is restricted by the demand response system. can do.
