Description

The present invention relates to a power management method and a power management device. In particular, it relates to an energy saving system that saves power consumption by controlling air conditioning or ventilation in a store such as a pachinko parlor.

In modern society, many air conditioners are used in various places for both cooling and heating purposes. These air conditioners are installed not only in ordinary houses but also in various places such as offices, factories, stores, and public facilities. Air conditioners with various capacities and characteristics are manufactured and sold according to 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 electric power. For example, in general households and stores, there is data that air conditioners consume 20 to 30% of the electric power consumed by all electrical equipment (see, for example, Patent Document 1).

Today, the depletion of fossil fuels and the increasing regulation and opposition to nuclear power are creating difficulties for the power generation industry and the power generation situation. In addition, in order to prevent global warming, regulations and strict eyes on power generation using fossil fuels are increasing. On the other hand, technological progress and widespread use of power generation using renewable energy such as wind power generation and solar power generation are still in progress. For this reason, energy saving to reduce power consumption is being called for worldwide. Under such circumstances, it is required in various countries and various fields around the world to reduce the power consumption of air conditioners.

Air-conditioning equipment currently on the market is provided with an inverter function in response to a decrease in temperature below a predetermined temperature during cooling and an increase in temperature above a predetermined temperature during heating. The inverter function reduces or stops the delivery of cold air when the temperature falls below a predetermined temperature while the cold air is being sent out at a temperature set by the user during cooling, for example. The opposite is true when the air conditioner is used for heating. It is believed that this inverter function can suppress the transmission of cold air or hot air that deviates from the set temperature, and as a result, can reduce power consumption.

However, in order to reduce power consumption and thus electricity charges, it is necessary to pay attention not only to the operation of the inverter function of the air conditioning equipment but also to the contracted power with the electric power company. Here, the contracted electric power means the contract value of the electric power supply concluded between the electric power company (for example, Tokyo Electric Power Company, Kansai Electric Power Company, etc.) and the electric power consumer (for example, the store operator) (for example, the contract value of the electric power supply). See Patent Document 2). The maximum demand power meter is used as a monitoring instrument for this contracted power. Since the measurement time is specified as 30 minutes in the electricity supply contract, this is called a 30-minute maximum demand power meter. Further, the demand power (demand) means the average power for 30 minutes defined by the electricity supply contract, and the maximum value in one month is called the maximum demand power (maximum demand).

For electricity consumers whose contract power is less than 500 kW, the so-called actual value contract is applied, and the contract power for that month is the maximum demand power (maximum demand) for the past year including the month measured by the maximum demand power meter. Is 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 the contracted power goes down, it will be possible to save electricity charges accordingly.

On the other hand, when the value of the maximum demand power meter is 500 kW or more, the power consumer and the power company are 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. The contract power will be decided after consultation. Currently, large stores such as supermarkets, specialty stores, and department stores often have contract power of 500 kW or more. Such electric power consumers are required to perform demand control in order to reduce electricity charges.

It can be executed based on a control device (hall computer device 55, or another computer device).

Explaining with reference to FIG. 2, the power management device (energy saving system, electricity cost saving system) 100 of the present embodiment includes an inverter frequency adjusting system 30 connected to an air conditioner device 20 including an inverter motor 24 and a ventilation fan 62. It is provided with a ventilation volume adjusting system 70 connected to a ventilation equipment device 61 including the above. The power management device 100 includes a system cooperative control device (55) that controls the inverter frequency adjustment system 30 and the ventilation volume adjustment system 70 in cooperation with each other. The system collaborative control device of the present embodiment may be a hall computer device 55 (or a computer device other than the hall computer device 55) in the store 50, or a computer device connected via the Internet 90 (or a computer device connected via the Internet 90). For example, it may be a server device 15).

If the security is strong, the information terminal (computer device) that can be connected to the Internet (communication network) 90 may be a system collaborative control device instead of the server device 15. Such an information terminal is typically a personal computer (PC), which is a communication device (eg, 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, a liquid crystal display device), an input device (for example, a keyboard, a mouse, etc.), a computing device (for example, a semiconductor integrated circuit device (IC) or a central computing device (CPU)), a storage device (for example, a hard disk, a semiconductor storage device). Etc.). Further, the information terminal is not limited to a personal computer (PC), and may be another device as long as it can operate the above-mentioned collaborative control, for example, a smartphone, a tablet terminal, a mobile phone, or the like. May be good. Further, the information terminal may be connected by another communication line, that is, an in-house LAN (wired LAN or wireless LAN) or the like for information communication without being connected to the Internet 90. Further, in the present embodiment, the fact that an information terminal (PC, smartphone, etc.) is connected means that the information terminal (PC, smartphone, etc.) is connected (communicable), and is physically connected by a wired cable. In addition to the case where it is connected, it also includes the case where it is connected by wireless or optical communication.

In this example, the hall computer device (or the computer device connected to the position) 55 will be described as a system collaborative control device. The system collaborative control device 55 is provided with an input device (keyboard, mouse, etc.) and a display device (liquid crystal display, etc.) on the premise that the system collaborative control device 55 is composed of a central processing unit (CPU) and a storage device for calculating data. ing.

Store congestion level data can be input to the system collaborative control device 55 of the present embodiment. In the store congestion level data, the level at the time of maximum congestion such as full occupancy / full occupancy is 100% (or "10" in the case of 10-level display), and the level at the time of minimum congestion with no people is 0% (or 0%). It is set to "1" or "0" in the case of 10-step display. The store congestion level data may be input by the staff by the input device by himself / herself, or may be input by something like a smartphone when remote input is possible. Alternatively, if the store congestion level data can be automatically aggregated from the information of the customers sitting on the pachinko machine, the automatically aggregated store congestion level data can be used.

Then, the system collaborative control device 55 of the present embodiment can realize the following functions. (3a) A function of calculating the ventilation ratio from the store congestion level data, and (3b) a function of 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 can be determined empirically or as processed data (for example, conversion table data) and processed. For example, when the ventilation ratio (or the required ventilation rate per hour) at the maximum congestion level (100%) is 8 times (8 cups), the ventilation ratio (required ventilation frequency per hour) at the congestion level (50%) is set. Set the store congestion level data so that it is 4 times (8 cups), and set the ventilation ratio (required ventilation frequency per hour) to 1.6 times (1.6 cups) at the congestion level (20%). It is possible to set the level data at the time of store congestion.

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

Then, the system collaborative control device 55 transmits the calculated control frequency data to the inverter frequency adjustment system 30. The inverter frequency adjustment system 30 can control the inverter motor 24 based on the transmitted control frequency. At the same time, the system collaborative 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 equipment device 61 based on the transmitted ventilation ratio.

Here, if the store congestion level is low (for example, 50%) and the ventilation ratio can be lowered (for example, 8 times → 4 times), it will be cold even at the same air conditioning set temperature (for example, 26 ° C.). Since the air (or warm air) is not discharged to the outside, the control frequency of the inverter motor 24 can be lowered (for example, the inverter motor control frequency such that the operation is 50%), and as a result, the power saving effect (power saving effect (). Alternatively, the effect of saving electricity costs) can be achieved. In addition, if the store congestion level is even lower (eg 20%) and the ventilation ratio can be further reduced (eg 8 times → 1.6 times), the same air conditioning set temperature (eg 26 ° C) However, since most of the cold air (or warm air) does not have to be discharged to the outside, the control frequency of the inverter motor 24 can be further reduced (for example, an inverter motor that operates at 20%). (Control frequency), and as a result, a larger power saving effect (or electricity cost saving effect) can be obtained.

In the conventional technology, the reduction of power consumption in air-conditioning equipment is measured by improving the performance of the inverter function and demand control function, and the actual situation is that they are competing for the improvement of the performance. However, if the energy saving system 100 according to the present embodiment is used, the energy saving effect can be remarkably achieved as compared with the energy saving using the inverter function and the demand control of the high level technology which can be considered at present. The electricity bill of the store 50 can be significantly reduced.

Further explaining, in the energy saving system 100 of the present embodiment, the ventilation volume adjusting system 70 connected to the ventilation device device 61 has a function (1b) of calculating the ventilation ratio from the operation rate data and the ventilation device based on the ventilation ratio. A function (1c) for controlling the device is included, and a function (2b) in which the inverter frequency adjusting system 30 connected to the air conditioning equipment device 20 including the inverter motor 24 calculates the control frequency of the inverter motor from the ventilation ratio. ) And the function (2c) of controlling the inverter motor based on the control frequency. As a result, 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, the power consumption in the store 50 such as a pachinko parlor can be saved. .. In addition, the system collaborative control device 55 of the present embodiment has a function of calculating the ventilation ratio from the store congestion level data (3a) and a function of calculating the control frequency of the inverter motor 24 (3b). 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, the power consumption in the store 50 such as a pachinko store can be saved. ..

The inverter frequency adjustment system 30 shown in FIG. 5 is a simplified version and a smaller version than the one shown in FIG. The inverter frequency adjustment system 30 shown in FIG. 5 can also execute the function described in FIG.

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

The ventilation volume adjusting system 70 shown in FIG. 6 is connected to the touch panel 75 by a wireless line in terms of information communication. The touch panel 75 shown in FIG. 6 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 by a wired circuit in an information communication manner, or the hall computer device 55 (or another computer device, touch panel device or smartphone device) may be connected without the touch panel 75. ) May be controlled. The ventilation volume adjusting system 70 of the present embodiment includes a housing (including a door portion) and a control circuit board arranged in the housing. Further, the ventilation volume adjusting system 70 shown in FIG. 6 includes a receiving unit for a radio signal from the touch panel 75. The connection between the ventilation volume adjusting 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), commands for individually controlling the ventilation fans 62 (for example, 77a to 77d) can be transmitted.

The control circuit board of the ventilation volume adjustment system 70 in the present embodiment has a function of reading the operating rate data from the hall computer device 55 (1a); a function of calculating the ventilation ratio from the operating rate data (1b); 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 operating rate data may receive the operating rate data via the touch panel 75. Further, when the system collaborative 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 volume adjustment system 70 determines the ventilation ratio from the hall computer device 55. It can be configured to execute the reading function (1a-2) and the function (1c) of controlling the ventilation fan 62 (ventilation device device 61) based on the ventilation ratio.

7 and 8 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, the area 50b is a toilet, the area 50c is a break room, the area 50d is a smoking corner, and the area 50e is. The doorway area, area 50f, is a prize corner, and the central area is a hall. 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 in each zone. Each air conditioner indoor unit 60 (60a to 60d) mainly performs air conditioning (cooling or heating) in each zone (50A to 50D).

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

FIG. 7 shows a case where the energy saving system 100 of the present embodiment does not perform zone control, and 70% rotation speed control (inverter motor frequency control) at a maximum output of 100% in each of the zones 50A to 50B. It is carried out. This rotation speed control (inverter motor frequency control) is not only determined by the set temperature (and / or demand data for energy saving) of the air conditioner, but also the store operation rate data (or store congestion level data). ) Is determined.

Even in the state shown in FIG. 7, appropriate air conditioning control is performed based on the operating rate data, but the inside of 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 / exit, a place exposed to direct sunlight, a place where people gather, and the like. The zone where the temperature change is small (for example, 50A) is a place far from the doorway, a place not exposed to sunlight, and the like.

Then, FIG. 8 shows a case where zone control is performed in the energy saving system 100 of the present embodiment. In the example shown in FIG. 8, in the zone (50D) where the temperature changes a lot, 80% rotation speed control (inverter motor frequency control) is performed, and the air conditioning in the zone (50D) is strengthened to increase the comfort level. ing. On the other hand, in the zone (50A) where the temperature change is small, the rotation speed is controlled by 60% (inverter motor frequency control), and the air conditioning in the zone (50A) is weakened to save the energy consumption of the air conditioning.

In FIGS. 7 and 8, the inverter motor frequency control (rotation speed control) is 60%, 70%, and 80%, but in the energy saving system 100 (inverter frequency adjustment system 30) of the present embodiment, it is 1%. Frequency control can be set for each. It is also possible to set the time (time) to be controlled by the energy saving system 100 (inverter frequency adjusting system 30) by setting the timer. Further, in FIGS. 7 and 8, the zone controls 50A to 50D of the indoor air conditioner 60 and the outdoor air conditioner 29 (air conditioning equipment device 20) by the inverter frequency adjustment system 30 have been described, but similarly, the ventilation volume adjustment system 70 is used. Zone controls 50A to 50D of the ventilation fan 62 (ventilation equipment device 61) can also be implemented. And, of course, the zone control 50A to 50D by the cooperation of both the inverter frequency adjustment system 30 and the ventilation volume adjustment system 70 can be implemented.

FIG. 9 is a flowchart showing an example of a usage method (operating method) of the energy saving system (power management device) 100 of the present embodiment.

As shown in FIG. 9, first, the operation of the ventilation volume adjusting system 70 is started (step S100), and then the operating rate is read from the hall computer 55 (step S110). Here, the operating rate is represented by, for example, 0% to 100% (or 0% to 120%, etc.). Next, it is determined whether or not the operation rate has been successfully read into the ventilation volume adjusting system 70 (step S120). Then, 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 volume adjustment system 70, and the ventilation fan is used at the ventilation ratio (for example, 0% to 100%). Control 62 and / or damper 68 (step S130). If the reading fails as a result of the determination (No), the process returns to step S110 again to read the operating 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 S200), and then the ventilation ratio is read from the ventilation volume adjustment system 70 (step S210). Next, it is determined whether the reading of the ventilation ratio is successful (step S220). Then, if the reading is successful as a result of the determination (Yes), the speed of the refrigerant gas is controlled (motor frequency control) by calculating from the ventilation ratio (step S230). If the reading fails as a result of the determination (No), the process returns to step S210 again to read the ventilation ratio.

When stopping the operation of the energy saving system 100, the control switch of the ventilation volume adjusting system 70 during operation is turned off (step S140), and when it is turned off (Yes), the operation ends (step S150). If it is not turned off, the process returns to the reading step (S110) and repeats the process until the operation stops. Similarly, in parallel, the control switch of the operating inverter frequency adjustment system 30 is turned off (step S240), and when it is turned off (Yes), the process ends (step S250). If it is not turned off, the process returns to the reading step (S210) and repeats the process until the operation stops.

In the method of the present embodiment, both the inverter frequency adjustment system 30 and the ventilation volume adjustment system 70 are operated in cooperation with each other based on the operation rate data (or the store congestion level data) of the store 50 to harmonize the air. It is better to dispose of the air in the store (cooled or heated air) to the outside more than necessary, and it is executed while controlling the appropriate air conditioning. As a result, it is possible to realize an energy saving effect (electricity cost saving effect) that cannot be exceeded by the conventional technology (high-performance air conditioning technology). In the flowchart shown in FIG. 9, the ventilation ratio was calculated by the ventilation volume adjustment system 70, but as described above, ventilation is performed by another arithmetic unit (for example, the hall computer device 55 or another computer device). After calculating the ratio and / or the adjusted inverter frequency, the ventilation volume adjusting system 70 and the inverter frequency adjusting system 30 may be made to cooperate with each other to perform the operation.

Next, the effect of saving (reducing) the air-conditioning electricity bill by the energy-saving system (electric power management device) 100 of the present embodiment will be described with reference to FIGS. 10 to 12.

FIG. 10A shows the configuration of the air conditioner device 20 including the air conditioner indoor unit 60 and the air conditioner outdoor unit 29. FIG. 10B shows an inverter motor 24 in the compressor 25 provided in the air conditioner outdoor unit 29. FIG. 10 (c) is a graph showing the time from the switch ON (98) of the air conditioner device 20 to the arrival (99) of the set temperature of the air conditioner.

On the other hand, FIG. 11A shows the inverter frequency adjusting system 30 of the present embodiment to the air conditioner outdoor unit 29 having the configuration shown in FIG. 10A via an adapter (inverter motor control frequency adapter) 22. Shows the configuration connected to. Similarly, FIG. 11B shows an inverter motor 24 in the compressor 25 provided in the air conditioner outdoor unit 29. FIG. 11C is a graph showing the time from the switch ON (98) of the air conditioner device 20 to the arrival (99) of the set temperature of the air conditioner.

Here, as an example of air conditioning in the store 50, a case where the room temperature is set to the set temperature (cooling temperature) as soon as possible in midsummer will be described. The case where the temperature inside the store when the air conditioner is not started is 30 ° C and the temperature when the air conditioner is started is 26 ° C (air conditioner set temperature) will be described. In the case of heating in the middle of winter, it can be understood as the opposite explanation.

First, as shown in FIG. 10A, when the air in the store 50 is cooled (air-conditioned), the air in the store (room temperature) is sucked in by the air-conditioning indoor unit 60 (arrow 91), and the temperature is 5 than the room temperature. Cooling air whose temperature has been lowered by about ° C. is discharged into the store (arrow 92). Then, the refrigerant in the pipe 60a extending from the air-conditioning indoor unit 60 to the outside of the store 50 carries the removed heat toward the compressor 25 (arrow 93). As shown in FIG. 10B, the operation of the inverter motor (compressor inverter motor) 24 in the compressor 25 causes the refrigerant (94) to move (downstream), and then as shown in FIG. 10A. In addition, the heat taken away is released to the outside through the fan 21 (arrow 95). After that, the refrigerant that has released heat (cold refrigerant) proceeds in the pipe 60a as shown by arrow 96, and then enters the store 50 as shown by arrow 97. Then, the heat is taken again through the air-conditioning indoor unit 60, and the taken heat is taken out of the store 50 as shown by the arrow 93. By repeating this operation, the inside of the store 50 is cooled.

The most important factor in saving electricity costs for an air conditioner (air conditioner) is the electric power (energy consumption) of the inverter motor 24, and the inverter motor 24 accounts for 90% of the electric power of the air conditioner. However, if it is a home air conditioner, you can use the method of not turning on the air conditioner (or lowering the set temperature of the air conditioner) even in the middle of summer, but the stores visited by customers (especially pachinko stores) 50 In, even though it is midsummer, not turning on the air conditioner (or raising the set temperature above the comfortable temperature) affects the number of customers, sales, and customer reputation. It cannot be changed (ie, set to a higher set temperature). Therefore, we will introduce a commercial air conditioner with a high power saving effect, but even though the power saving effect can be obtained to some extent, a large effect (the effect of saving millions of yen in one year) cannot be obtained. Was the reality.

As shown in FIG. 10C, when the air conditioner is switched on at 8:00 am, the inverter motor 24 operates at full capacity (100% rotation) toward the air conditioner set temperature, and the set temperature is set at 10 am two hours later. To reach. If 10 am is the opening time of the pachinko parlor, the air inside the pachinko parlor 50 is harmonized at the set temperature from that point on, so that customers can play comfortably.

On the other hand, when the inverter frequency adjustment system 30 of the present embodiment is connected to the inverter motor 24 and controlled, the result is as follows. As shown in FIG. 11A, the air in the store (room temperature) is sucked by the air conditioning indoor unit 60 (arrow 91). At this time, in the case of FIG. 10A, the cooling air 92 having a temperature about 5 ° C. lower than that of the outside air was discharged, but in the case of FIG. 11A, the cooling air 92 having a temperature about 4.2 ° C. lower than the outside air was discharged. To discharge. That is, the cooling air 92, which is higher by about 0.8 ° C. than that in FIG. 10A, is discharged. This slight difference is the key to achieving a large power saving effect.

After that, as in FIGS. 10A and 10B, in FIGS. 11A and 11B, the refrigerant in the pipe 60a extending from the air conditioning indoor unit 60 to the outside of the store 50 takes away the heat. Carry it toward the compressor 25 (arrow 93). As shown in FIG. 11B, the operation of the inverter motor (compressor inverter motor) 24 in the compressor 25 causes the refrigerant (94) to move (downstream), and then as shown in FIG. 11A. In addition, the heat taken away is released to the outside through the fan 21 (arrow 95). After that, the refrigerant that has released heat (cold refrigerant) proceeds in the pipe 60a as shown by arrow 96, and then enters the store 50 as shown by arrow 97. Then, the heat is taken again through the air-conditioning indoor unit 60, and the taken heat is taken out of the store 50 as shown by the arrow 93. By repeating this operation, the inside of the store 50 is cooled.

In the cases of FIGS. 11A and 11B, the operation of discharging the cooling air 92, which is about 0.8 ° C. higher than that of FIG. 10A, is performed, so that the rotation speed (control) of the inverter motor 24 is performed. Frequency) will be slightly lower. As a result, as shown in FIG. 11C, when the air conditioner is switched on at 8:00 am, the inverter motor 24 has a slightly saved rotation speed (less than 100% saved rotation) toward the air conditioner set temperature. The set temperature is reached at 10:30 am after 2 hours and 30 minutes. That is, the set temperature is reached 30 minutes later than the operation shown in FIG. 10 (a). If the pachinko parlor is open at 10:30 am, the air inside the pachinko parlor 50 is harmonized at the set temperature from that point on, so that customers can play comfortably. If 10 am is the opening time, switch on at 7:30 am. Here, if the difference between the two is compared to a vehicle, the operation of FIG. 10A is in the normal mode, and the destination is reached quickly with emphasis on speed (in other words, the set temperature is reached quickly). On the other hand, the operation of FIG. 11A is an eco mode (energy saving mode), and the reach distance does not change even slowly, and fuel efficiency is emphasized (in other words, the set temperature is reached, but only a little more than in the normal mode. time consuming). Then, when the operation is performed as shown in FIG. 11A, the maximum demand value can be suppressed as compared with the operation shown in FIG. 10A, and as a result, the electricity charge can be significantly reduced. Details of this point will be described later.

FIG. 12A 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. 12B 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. 12A, when the customer attraction rate (average occupancy rate) is 100% (that is, the occupancy rate data or the store congestion level data is 100%), the ventilation fan 62 is operated at a ventilation ratio of 100%. Then, the rotation speed (inverter frequency) of the inverter motor 24 that moves the refrigerant passing through the indoor air conditioner 60 is adjusted corresponding to the ventilation ratio of 100%.

On the other hand, as shown in FIG. 12B, when the customer attraction rate (average occupancy rate) is 20% (that is, the occupancy rate data or store congestion level data is 20%), the ventilation fan 62 is operated at a ventilation ratio of 20%. Let me. Then, the rotation speed (inverter frequency) of the inverter motor 24 that moves the refrigerant passing through the indoor air conditioner 60 is adjusted corresponding to the ventilation ratio of 20%. It should be noted that the customer attraction rate (average occupancy rate, occupancy rate data, store congestion level data) and the ventilation ratio do not necessarily have to match, and it is sufficient that they have a relationship with each other. Then, the value of the ventilation ratio can be determined based not only on the ratio of attracting customers but also on the amount of smoking and the amount of smoke and odor.

By using the energy saving system 100 of the present embodiment, an appropriate ventilation ratio and inverter frequency can be set according to the customer attraction rate (average operating rate), and as a result, electricity cost saving can be achieved. Here, when the customer attraction rate (average operating rate) as shown in FIG. 12B is 20%, the ventilation fan 62 is operated with the ventilation ratio kept at 100%, paying attention only to the set temperature of the air conditioner. If this happens, a large amount of air cooled by the air conditioner (many cups per hour) will be thrown out of the store 50 and new outside air (hot air in midsummer) will be taken in, so it will be necessary to operate the air conditioner at full capacity. .. In that respect, if the energy saving system 100 of the present embodiment is used, an appropriate ventilation ratio and inverter frequency are set according to the customer attraction rate (average operating rate), so that energy saving (power saving and electricity cost suppression) can be achieved in a comfortable air-conditioned environment. Can be executed.

On the contrary, if the set temperature of the air conditioner is raised when the customer attraction rate (average operating rate) as shown in Fig. 12 (a) is 100%, only considering the saving of electricity costs, a comfortable air conditioning environment It will be far from the above, and it will have an adverse effect on attracting customers and sales. In addition, when the customer attraction rate (average occupancy rate) as shown in FIG. 12A is 100% and the ventilation ratio is set to 20%, tobacco smoke and the like remain filled ( If you serve food, the smell of the food will remain full), and it will be far from a comfortable store environment, which will also have an adverse effect on attracting customers and sales. Then, by using the energy saving system 100 of the present embodiment, it is possible to set an appropriate ventilation ratio and inverter frequency according to the customer attraction rate (average operating rate), so that a significant power saving effect can be achieved while realizing a comfortable environment. Can be achieved.

Next, with reference to FIGS. 13 and 14, the effect of saving the electricity bill for air conditioning by the energy saving system (electric power management device) 100 of the present embodiment will be continuously described. FIG. 13 is a graph in which the month of one year is on the horizontal axis and the maximum demand value (kW) is on the vertical axis. Then, FIG. 14 is an equation showing that the electricity charge is the sum of the basic charge and the electric energy charge.

Among the stores 50, the one that most affects the electricity price is the electricity bill of the air conditioner (air conditioner), and 90% of the electricity bill of the air conditioner (air conditioner) is related to the inverter motor 24. Then, in order to reduce the electricity charges of the store 50, it is usually necessary to reduce the amount of air conditioning equipment (air conditioner) used, or to raise the set temperature for cooling (lower for heating). It is said. 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 becomes the contract power for the next year. ..

Therefore, in the usage state of the graph shown in FIG. 13, since the maximum demand value in August on the left side is 150 kW (D1 point), the contract power is 150 kW. However, since the maximum demand value in August on the right side is 160 kW (D2 points), the contract power for the next year will be 160 kW. That is, as shown in FIG. 14, the basic charge is determined by the product of the contracted power (maximum demand value for the past year) and the charge unit price, and the electric energy 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. 13, it is important that the basic charge (contract power based on the maximum demand value) is not set to 160 kW (it is important to keep it at 150 kW), and the electricity charge is compared with that. Focusing on reducing (electricity used in a month) may limit the effect of reducing electricity charges. Then, in order to forcibly suppress the maximum demand value, if a power rise curve that causes the maximum demand value to exceed the set value (for example, 150 kW) is detected, the air conditioner (or other electric device (refrigerator, etc.)) ) Is forcibly turned off, the air conditioner (air conditioner) stops even in the middle of summer, resulting in an unpleasant store 50, or a malfunction of other electrical equipment (for example, the refrigerator is stopped). Etc. are brought about, which is not preferable.

In the energy saving system (electric power management device) 100 of the present embodiment, the following method is applied to control the maximum demand value, and a large electricity cost saving is achieved while being a comfortable air-conditioned space.

That is, first, 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. 10 (c), it takes a little time as shown in FIG. 11 (c). Even so, the inverter motor 24 is controlled so that the inverter frequency is slightly lowered to the set temperature (99). As a result, it is possible to prevent the maximum demand value from becoming large. Then, by suppressing the maximum demand value, the basic contract can be revised to the lower one, and in one example, the electricity charge can be reduced by 30%.

Next, by determining the ventilation ratio (operation of the ventilation equipment) according to the customer attraction rate (average occupancy rate or occupancy rate data, store congestion level data), the customer attraction rate is low and clean air-conditioned air is not polluted. It is possible to prevent the air-conditioned air from being thrown out to the outside when the is in the store 50. As a result, it is possible to obtain the effect of suppressing the maximum demand value and the effect of reducing the electric energy charge (electric power used in one month).

Furthermore, by adjusting the inverter frequency according to the customer attraction rate (average operating rate or operating rate data, store congestion level data), the ventilation ratio is small and a large amount of air-conditioned air remains in the store 50. At that time, it is possible to forcibly suppress the operation of the inverter motor 24 at the inverter frequency corresponding to the set temperature. That is, when the ventilation ratio is low, the effect of suppressing the maximum demand value and the effect of reducing the electric energy charge (electric power used in one month) are obtained by lowering the rotation speed of the inverter motor 24 accordingly. be able to.

In addition, as shown in FIG. 8, air conditioning / ventilation control can be performed by zone control. As a result, 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 electric energy charge (electric power used in one month) can be obtained.

Using the method described above, the store 50 equipped with the energy saving system (electric power management device) 100 of the present embodiment can achieve the effect of saving electricity costs of about one million yen to several million yen in one year. Can be done.

Next, in the energy saving system (power management device) 100 of the present embodiment, the control of the ventilation ratio by the zone control will be described with reference to FIGS. 15 and 16. Since the air conditioning control in the zone control is described in FIGS. 7 and 8, it can be understood together with it.

The store 50 shown in FIG. 15 is a pachinko store (pachinko hall). Here, the store 50 is divided into areas 1 to 4, and ventilation areas of zones 1 to 4 are allocated correspondingly. The ventilation fan 62 of each zone (zones 1 to 4) is connected to the duct 66, and the intake 71 and the exhaust 72 are performed at the end of the duct 66 (intake port / exhaust port with the outside). Further, the ventilation fan 62 is controlled by the ventilation volume adjusting system 70, and the ventilation volume adjusting system 70 is operated by a command from the hall computer device 55 and the touch panel 75.

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

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

FIG. 16 shows a display screen 55a of the hall computer device 55. The pachinko operating rate software 80 is operating in the hall computer device 55, and the operating rate data is displayed on the display screen 55a. The operating rate is 200 units, the non-operating unit is 200 units, and the average operating rate is 50%. However, since the operating rates of each area (each zone) are also tabulated here, the ventilation operation according to the operating rate. By executing, the ventilation / air conditioning operation can be performed efficiently. That is, it is possible to perform the ventilation / air conditioning operation at an average operating rate of 50%, but it is possible to obtain the power saving effect more efficiently by performing the ventilation / air conditioning operation by 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 reducing the electric energy charge (electric power used in one month).

In the above-described embodiment, the electricity cost saving effect based on the structure or function of the energy saving system (power management device) 100 has been described, but it is preferable to prevent human error in obtaining the electricity cost saving effect. The most important point in human error is to ignore the energy saving method (power management method) according to this embodiment (ignoring the manual) and let the staff change the air conditioning set temperature without permission (if cooling). To lower the set temperature).

Explaining with the example shown in FIG. 11C, when the energy saving system 100 of this embodiment is used, the set temperature is properly reached at 10:30 am, but the air conditioner is hot in midsummer. There is a possibility that some people will change the set temperature of the above to an extremely low temperature (for example, 17 ° C) without permission. The energy-saving system 100 of the present embodiment is intended to exert a remarkable effect of saving electricity cost in setting the set temperature (for example, 26 ° C.). Therefore, when the set temperature is set to 17 ° C., the set temperature is set. Inverter frequency control is activated according to the above, and as a result, there is a possibility that the maximum demand value will exceed that of the contracted power. Then, the effect of suppressing the electricity bill cannot be obtained.

Of course, the staff is not malicious and does it to avoid the heat of midsummer, so if it is a short time in the morning, you may think that it is okay to ignore the manual / rule, and the maximum demand value May not be distracted by the fact that is linked to contract power. And the staff (or the team including their boss) may return the set temperature according to the manual rule at the time when the manager comes (for example, 10 am), so why can not control the electricity bill? It may take time to investigate the cause of the problem.

FIG. 17 is a block diagram for explaining a modified example of the energy saving system 100 of the present embodiment. The energy saving system 100 shown in FIG. 17 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 transmitting 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 telephone that cannot make a call and distributes information) is used as the signal transmitting device 39. The signal transmitting 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 transmitting device 39 is connected to the hall computer device 55 (see wiring 103). Further, the hall computer device 55 is connected to the ventilation volume adjusting system 70 by the 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 100 shown in FIG. 17, the signal transmitting device 39 obtains 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 adjusting system 30), and obtains the set temperature thereof. Is automatically transmitted to the Internet 90. Further, the signal transmitting device 39 can transmit data (air conditioning data) such as real-time demand value, operating rate data (or store congestion level data), ventilation ratio, and store temperature, together with the air conditioning set temperature. .. As a result, the staff can know that the set temperature of the air conditioner is changed without permission, and as a result, it is possible to prevent the maximum demand value from increasing (the electricity rate increases).

Further, the check for the change in the set temperature may be performed by the information terminal 16 connected to the Internet 90 without checking by the hall computer device 55. The configuration example shown in FIG. 17 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 smartphone, a tablet, a notebook PC, etc.) 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 checked anywhere and anytime. Since it does not have to be one specified information terminal 16, for example, a plurality of people such as a pachinko parlor owner, a pachinko parlor manager, and a system manager can check the set temperature change (or a demand value) at the same time. Check) can be performed.

In the present embodiment, the information terminal 16 is a smartphone as shown in FIG. 18 (for example, an iPhone manufactured by Apple Inc. (registered trademark), a smartphone equipped with an Android OS (various Android smartphones)). A smartphone is a multifunctional mobile phone, equipped with a call function and an Internet communication function, and can manage, process, and transmit information as well as a call function. However, if it is possible to check the set temperature change (or check the demand value), it is not limited to smartphones, but if it is capable of information communication, it is a mobile phone (for example, a so-called feature phone). It may be a terminal such as a personal computer (for example, a desktop PC), a game machine, or a television. In addition to smartphones and mobile phones, tablet computers, laptop computers, and wearable computers can also be used as portable communication devices (information communication terminals).

FIG. 18 is 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 a button (main button) 230. A switch button 211 is provided on the side surface of the housing 210. The display unit 220 is a touch panel type 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 an "application") is displayed on the display unit 220. The application can be operated by touching the icon (260 or the like) of the display unit 220. The set temperature change check application (smartphone application program) in the present embodiment is downloaded through the Internet line and introduced into the smartphone 200, and is displayed as the application icon 250 of the present embodiment. When the application icon 250 is pressed, the set temperature change check application is launched, and the set temperature change check (and / or the real-time or predetermined time demand value check) can be performed there. Depending on the configuration of the application, the set temperature of the air conditioner device 20 of the store 50 may be changed by remote control. If such a remote control function is introduced, the maximum demand value will increase even when the checker (administrator) is far away and it takes time to change the air conditioning temperature setting (electricity charges will increase). It can be prevented or suppressed. The same process 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 of executing arithmetic processing operation and / or control operation 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 those arithmetic processing operations and / or control operations programmatically (by software).

As an example, in the power management device 100 that controls both the air conditioner and the ventilation device, the system collaborative control device that jointly controls the ventilation ratio and the inverter frequency adjustment is constructed by software. Can be constructed as shown in FIG. The system collaborative control device 150 shown in FIG. 19 includes a central processing unit 160 for calculating data and a storage device 170. The system collaborative control device 150 may use the central processing unit (160) and the storage device (170) in the hall computer device 55, or may use 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 collaborative 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. It may be common to the input unit 151 and the output unit 152. Further, the wiring 105 and the wiring 107 may be common, and the wiring 105 and the wiring 107 may both be wireless (for example, WiFi, wireless LAN, radio waves for mobile phones, etc.). A power management program (or an air conditioning electricity cost saving program, an energy saving program) 180 is stored in the storage device 170 of the system collaborative control device 150. The power management program 180 may be configured to be downloadable through wiring 105 (or may be downloadable from the server device 15 in FIG. 1 via the Internet 90).

In the configuration of the present embodiment, when the power management program 180 of the system collaborative control device 150 is activated, the central arithmetic unit 160 and the storage device 170 operate in cooperation with each other, so that the system collaborative control device 150 has the following Functions are realized: (4a) Function to read store congestion level data (161); (4b) Function to calculate ventilation ratio from store congestion level data (162); (4c) At least store congestion level data and ventilation ratio A function of calculating the control frequency of the inverter motor 24 from one of them (163); (4d) a function of transmitting at least one of the ventilation ratio and the control frequency of the inverter motor 24 (164).
The power management program 180 is not limited to the case where it is stored in the storage device 170, and the program is started there in a state where it is stored in a storage device (for example, a cloud memory on the Internet) in another place. The functions (161 to 164) of the system collaborative control device 150 may be realized.

Then, 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 collaborative control device 150: (5a) Store congestion level data (171) ( 5b) Ventilation ratio data (172) (5c) Control frequency data of inverter motor 24 (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 conditioning outdoor unit information, individual ventilation fan information, etc.) (174).
In the present embodiment, the data (171 to 174) is stored in the storage device 170 of the system cooperation control device 150, but it may be stored in a storage device (for example, a cloud memory on the Internet) in another place. I do not care.

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

The arithmetic processing operation and / or the control operation can be executed programmatically (software-wise) by the ventilation volume adjustment system 70 and / or the inverter frequency adjustment system 30 described above.

For example, the ventilation volume adjustment system 70 includes a central processing unit 160 and a storage device 170 as shown in FIG. 19, and by activating the ventilation volume adjustment program (180), the central processing unit 160 and the storage device are included. When the 170s operate in cooperation with each other, the function of the ventilation volume adjusting system 70 can be realized. Such functions include, for example, (1a) a function of reading operating rate data from the hall computer device 55; (1b) a function of calculating a ventilation ratio from the operating rate data; (1c) a ventilation device based on the ventilation ratio. It includes a function of controlling the device 61; Of course, in actual application, various modifications can be made according to the environmental conditions and setting conditions. Then, the processing data and the calculation result data associated therewith can be stored in the storage device 170.

The inverter frequency adjustment system 30 includes a central processing unit 160 and a storage device 170 as shown in FIG. 19, and by activating the inverter frequency adjustment program (180), the central processing unit 160 and the storage device are included. When the 170s operate in cooperation with each other, the function of the inverter frequency adjustment system 30 can be realized. Such functions include, for example, (2a) a function of reading the ventilation ratio from the ventilation volume adjustment system 70; and (2b) a function of calculating the control frequency of the inverter motor 24 in the air conditioner 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 the environmental conditions and setting conditions. Then, the processing data and the calculation result data associated therewith can be stored in the storage device 170.

In addition, in the energy saving system 100 shown in FIG. 17, the power management program (180) has a function of (6a) comparing the air-conditioning temperature set value during operation with the input air-conditioning set temperature; (6b) comparison determination data. It may have a configuration for realizing the function of transmitting. Such a function can be realized by a computer device or the like (for example, 55, 39) in the store 50.

Next, FIG. 20 is a flowchart showing an example of how to use (operate) the energy saving system (power management device) 100 having the configuration shown in FIG.

First, the store congestion level in the store 50 is set (step S300). In the hall computer device 55 (or the computer device in which the system collaborative control device is realized) as shown in FIG. 16, the operating 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 occupancy rate is used as it is.

Next, the store congestion level is input (step S310). In the example shown in FIG. 17, the occupancy rate (store congestion level) is 40%, 70%, 30, 60%, and these values are input. The store congestion level can be input automatically by the computer device (55) or by a person. It is preferable to use real-time numerical values and data for the store congestion level, but average values and predicted values can also be input.

Next, the system collaborative control device 55 (150) calculates the ventilation ratio from the store congestion level (step S320). As described above, the calculation of the ventilation ratio may be performed by the ventilation volume adjusting system 70. Then, the control frequency of the inverter motor 24 is calculated by the system collaborative control device 55 (150) (step S330). As described above, the calculation of the control frequency may be performed by the inverter frequency adjustment system 30.

After that, the inverter frequency adjustment system 30 controls the inverter motor 24 based on the calculated control frequency (step S340). On the other hand, the ventilation equipment device 61 (ventilation fan 62) is controlled by the ventilation volume adjustment system 70 based on the calculated ventilation ratio. 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. 11, the inverter is operated at full capacity so that the maximum demand value does not increase. The control is performed so that the inverter motor 24 is rotated a little more slowly than the motor 24 is rotated.

Subsequently, a step of transmitting various system data is performed (step S360). The system data here is, for example, the manual (or initial setting value) air conditioning set temperature, the operating air conditioning set temperature, the match / mismatch judgment data between the set initial value and the operating air conditioning set temperature, and 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 transmitting device 39. The system data may be transmitted from the hall computer device 55 to the Internet 90.

The data transmitted in step S360 can be viewed on the information terminal 16 (for example, the smartphone 200) via the Internet 90. Similarly, it can be confirmed by the 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 abnormality in the demand value (unexpected value) occurs, it becomes possible to immediately deal with it. Even by such error prevention (particularly, operation error and human error), it is guaranteed to secure the energy saving effect (significant effect of suppressing the electricity bill).

Next, FIG. 21 is a flowchart showing an example of another usage method (operating method) of the energy saving system (power management device) 100 of the present embodiment. The method shown in FIG. 21 is a flowchart focusing on the most important demand value for suppressing the electricity bill and the prevention of an arbitrary change in the air conditioning set temperature.

First, the air conditioning temperature is set in the store 50 (step S400). The air-conditioning temperature setting here may be set to a more comfortable air-conditioning set temperature in anticipation that the electricity bill can be reduced by the method of the present embodiment, or a little comfort is provided in order to maximize the reduction of the electricity bill. The air-conditioning temperature may be set according to the dropped response. Further, 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, the control rotation speed of the inverter motor 24 is calculated (step S410). Here, as shown in FIG. 11, the calculated control rotation speed is a value such that the inverter motor 24 is rotated a little more slowly than the inverter motor 24 is rotated at full operation so that the maximum demand value does not increase. calculate. As a result, it is possible to prevent the maximum demand value from becoming too large. The control rotation speed to be calculated is not limited to a fixed value, and may be a numerical value that varies depending on the time (or the temperature inside the store).

Next, the inverter motor 24 is controlled based on the calculated control rotation speed (step S420). 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 device is measured (or the demand value of the entire store 50 is measured) (step S430). By measuring the demand value of the inverter motor 24 or the store 50 in real time (in addition to the actual continuous real time, real time at intervals of 1 minute, 10 minutes, 15 minutes, 30 minutes, etc.) , It is possible to prevent the maximum demand value from becoming large.

In addition, the demand value is measured and the air conditioning temperature set value is acquired (step S440). Here, the reason why the air-conditioning temperature set value is acquired is that the staff of the store 50 may change the air-conditioning temperature set value without permission. If the set value of the air conditioning temperature is changed, the inverter motor 24 is controlled accordingly, so that the possibility that the maximum demand value becomes large cannot be excluded. To prevent such a situation, acquire the air-conditioning temperature set value as appropriate (or always) so as to achieve the expected air-conditioning schedule and reduction of electricity costs.

Next, the air conditioning temperature set value acquired in step S440 is wirelessly transmitted as data (step S450). In the configuration of the present embodiment, data is transmitted by the signal transmitting device 39 that transmits information to the Internet 90. Wired data transmission is also possible, but in that case, the data of the air conditioning temperature set value will be lost due to a failure such as turning off the power of the computer device that has the information (air conditioning temperature set value) or not needing to connect to the Internet. It may not be uploaded. Since the data transmission here is mainly based on the air conditioning temperature set value, the amount of data is small, so that the communication charge is low even if the data is constantly transmitted to the Internet 90 wirelessly. Therefore, the burden is small even with constant wireless transmission, and the merit of constant monitoring is greater.

Then, the data transmitted in step S460 is received by the smartphone 16 (200) and displayed on the smartphone 16 (step S460). By displaying the data of the air-conditioning temperature setting value (or the discrepancy data (or discrimination data) between the air-conditioning temperature setting at the time of setting and the operation) in real time, it is possible to prevent the maximum demand value from becoming large due to human error. As a result, the expected reduction in electricity costs can be achieved.

Further, the function described above is mainly a function name seen from one device, that is, "send" and "receive" are paired terms, so that the function seen from the other device is not included. It should be added that the names of terms change.

Although the present invention has been described above in terms of preferred embodiments, such a description is not a limitation, and of course, various modifications can be made. 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, bookstores, coffee shops, restaurants, casino stores, rental videos, drug stores). It is a thing. In that case, the hall computer device 55 has a software system suitable for the store installed. In addition, the energy-saving system (electric power management system) 100 of the present embodiment includes, for example, a plurality of effective features, each of which independently exerts a sufficient technical effect, and is such a single unit. Active use of features is also of high technical value. The above-mentioned features can be applied to each other as long as they do not contradict each other, and further, the features on the system / device can be combined with the features of the process (or program), and conversely, the features of the process (or the program). Alternatively, it is possible to combine the above features (program) 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 is specifically stored in the program itself or the program. It is also possible to commercialize the recorded recording media and downloadable program products as intellectual property.

As one of the modified examples of this embodiment, the configuration as shown in FIG. 22 can be given. The energy saving system 100 shown in FIG. 22 is basically the same as that shown in FIG. 1, but has a configuration in which the power meter (wattmeter) 81 of the store 50 is connected to the inverter frequency adjustment system 30. There is. 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 51 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. It is possible to add a function to prevent it from being stored. This control (that is, the control that executes the function of preventing the contract power from increasing) is manually or automatically performed while observing the power consumption of the power meter on the remote monitoring device 15 (or the information terminal 16 in FIG. 17). It is also possible to do it.

Further, in the energy saving system 100 shown in FIG. 22, a thermometer that measures the temperature of the air in the store 50 is measured separately from the thermometer for setting the temperature of the air conditioner (or the temperature sensor incorporated in the indoor unit 60). (Temperature sensor) 89 is provided. The thermometer 81 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 performed according to the actual temperature of the air in the store. The number of thermometers 81 is not limited to one, and a plurality of thermometers 81 can be arranged. For example, the thermometers 81 can be provided in each region (50a to 50f) shown in FIG. Since the customer or staff in the store 50 feels heat or cold not by the temperature detected by the temperature sensor of the air conditioner device 20 but by the actual temperature of the air in the store, the actual temperature of the air is detected. Incorporating the information of the temperature sensor 89 into the energy saving system 100 leads to more comfortable air conditioning control.

The settings (user settings) made by the user who uses the energy saving system 100 (for example, the staff of the store 50 or the staff of the management company) include setting the room temperature of the air conditioner device 20 and setting the inverter motor 24. There is a setting for the upper limit of the frequency. The room temperature of the air conditioner device 20 is usually set by the remote controller of the indoor unit 60 (remote controller of the air conditioner), but it may be set by the energy saving system 100 of the present embodiment. Further, a function of incorporating the set temperature of the remote controller of the indoor unit 60 into the energy saving system 100 (or the inverter frequency adjusting system 30) may be provided. The setting of the upper limit value of the frequency of the inverter motor 24 is one of the important settings for preventing the inverter motor 24 from rotating excessively to save power. Even though the upper limit is set to 70%, if the user (for example, the staff of the store 50) changes the setting to 100% without permission, the contract power will increase. To prevent this from happening, the signal transmitter 39 shown in FIG. 17 can transmit information on the upper limit of the frequency of the inverter 24 (or a signal that its setting has been changed), and the contract power can be transmitted. It is possible to prevent it from rising. This function can be executed not only by communication by the signal transmission device 39 but also by transmission from the hall computer device (system collaborative control device) 55 in the energy saving system 100 to the Internet 90. In addition, in the flowchart shown in FIG. 21, the acquisition of the air conditioning temperature set value is mainly described, but instead of the air conditioning temperature set 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 (with both the set value and the frequency upper limit value of the inverter motor 24). As described above by way of example, such a modification can be performed.

According to the present invention, it is possible to provide a energy saving system to save power consumption by controlling the air conditioning in a store such as a pachinko parlor.
