Background art

[0002] In recent years, where there is a concern about the impact of carbon dioxide emissions on the environment, it is necessary to reduce the amount of energy used in many facilities. For example, facilities such as office buildings, factories, hotels, schools, and hospitals are equipped with various types of electricity use facilities, and it is desired to reduce the power consumed by these facilities.

Disclosure of the invention

Problems to be solved by the invention

[0003] Energy saving measures in facilities such as office buildings are important from the viewpoint of cost reduction (and legal compliance in some countries), and various measures have been proposed. There is a system that simulates the use of energy while exercising energy, so that people such as facility managers and users can practice while experiencing the effects of energy conservation under various energy conservation measures. Had not been.

Means for solving the problem

[0004] Therefore, the present invention provides an energy-saving training system in which humans can learn the effects of energy-saving measures by simulating the use of energy in facilities.

According to the present invention, there is provided an energy-saving training system (100) for a human to practice the effect of energy-saving measures in a facility. The energy saving training system (100) includes a pump training facility (B), a compression training facility (A), and a lighting apparatus training facility (C). The pump training facility (B) includes a pump (20), means (22) for changing the operating conditions of the pump in accordance with human operation, and power consumption of the pump accompanying the change in the operating conditions of the pump. Means (22) for presenting a change to the human. The compression training facility (A) includes means (13) for changing operating conditions of the compressor according to the human operation, Means (13) for presenting a change in power consumption of the compressor accompanying a change in operating conditions of the compressor to the person. The lighting device training facility (C) includes a lighting device (30), means (31) for changing the driving conditions of the lighting device in accordance with the human operation, and power consumption due to changing the operating conditions of the lighting device. Means (31) for presenting the change to the human.

[0006] Most of electric power in actual facilities such as factories is consumed by pump equipment, compressor equipment, and lighting equipment. According to the present invention, operating conditions such as driving conditions and driving conditions are changed in accordance with human operation, and a change in power consumption accompanying the change is presented. Therefore, a human confirms the effect on predetermined energy saving measures. It is possible. As a result, humans can effectively practice necessary measures for energy saving of facilities and their effects through actual operation of equipment.

[0007] The energy saving training system (100) is preferably housed in a transportable container (1). In this case, by connecting the container and the vehicle and moving, it is possible to go to the place where the trainees are and provide training on energy saving measures.

[0008] Further, in the energy-saving training system (100), the total power supplied to the pump training facility (B), the compression training facility (A), and the lighting apparatus training facility (C) is detected, It is preferable to provide consumption monitoring equipment (51, 52, 53, 54) that monitors the average power consumption per unit time or the power consumption per unit time based on the detection result. In this case, the average power consumption per unit time or the amount of power consumption per unit time for all the above facilities was monitored. Humans can also learn about average power consumption or energy consumption. In other words, what is the effect of energy saving measures of pump equipment on the amount of energy consumption, or the effect of reducing energy consumption by combining energy saving measures of compressor equipment with energy saving measures of lighting equipment? It is possible to experience the combined effect of energy saving measures in one system, and to practice the comprehensive effect of energy saving measures.

[0009] The consumption monitoring facilities (51, 52, 53, 54) predict and predict the average power consumption per unit time or the power consumption per unit time based on the detection result of the total power. It is preferable to trigger an alarm when the average power consumption or power consumption exceeds a threshold. Masire, Monitoring that the average power consumption per unit time or the power consumption per unit time does not exceed the threshold is important from the viewpoint of reducing power consumption over a longer period. In addition, some power supply companies may set the basic fee to be paid by the facility based on the maximum amount of power consumption per unit time (for example, 30 minutes) or the average power consumption per year. By issuing an alarm when the predicted average power consumption per unit time or power consumption exceeds a threshold, humans can implement energy-saving measures in equipment, and furthermore, Measures are effective ^ Ability to learn S

[0010] The consumption monitoring equipment (51, 52, 53, 54) performs control to reduce the electric load of the specific device (41-43) when the predetermined condition is satisfied after the alarm is activated. Prefer, to perform. According to the present invention, when a predetermined condition is satisfied after the alarm is activated, the electric load of the specific device is reduced. Can be realized. Reducing the electric load includes stopping the supply of power to a specific device and reducing the power consumed by the specific device. For example, when the specific device is an air conditioner, a process for reducing the air flow is included. In addition, it is preferable that the specific device is an auxiliary device that is provided independently of the pump training device, the compression training device, and the lighting device training device and that operates during the training. In this case, the electrical load of auxiliary equipment provided independently of the pump training equipment, compression training equipment, and lighting training equipment will be automatically reduced, but the equipment targeted for the main training will not be affected. Therefore, it is possible to proceed with the training smoothly without interrupting the main training.

[0011] According to another feature of the present invention, an energy-saving training system (100) for a human to practice the effect of energy-saving measures in a facility includes a pump (20), a plurality of pipes having different diameters, A switching valve for selectively connecting the plurality of pipes to an output port of the pump; a measuring means (22) capable of measuring a pressure loss in each of the pipes; and a longer pipe than the true pipe length of each of the pipes A flow control valve is provided in each of the pipes so that a pressure loss generated in a pipe having a pipe length can be simulated by adjusting an opening degree.

[0012] In the actual facility such as a factory, a pipe with the same length as the pipe connected to the pump Incorporation into the system increases the size of the training system. On the other hand, it is known that the pressure loss of a pipe increases as the length of the pipe increases. According to the present invention, in order to obtain a pressure loss equivalent to a pressure loss that occurs in a pipe length longer than the true pipe length of each pipe, the pipe for training is provided with a flow control valve. By adjusting the opening of the flow control valve, it is possible to simulate the pressure loss of a long pipe length, and to reduce the size of the training system. It is particularly useful when the energy-saving training system is housed in a container. Brief Description of Drawings

FIG. 1 is a plan view of an energy-saving training system according to an embodiment of the present invention.

[Fig. 2] It has three graphs to explain the energy saving measures of the pump equipment used in the system and its effects.

FIG. 3 is a block diagram showing an electrical configuration of the system.

FIG. 4 is a graph for explaining an example of a consumption monitoring operation executed in the system.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a plan view of an energy-saving training system according to an embodiment of the present invention. The energy-saving training system 100 is housed in a container 1 that can be moved by a vehicle. Container 1 has a door la and a door lb. The door la is connected to the floor of the container 1 by a hinge and opens toward the outside of the container 1. In the open state, the door la and the floor of Container 1 are flush with each other without steps, providing an entrance for humans (apprentices) to enter the apprenticeship system.

[0015] The interior of the container 1 is roughly divided into three regions by a partition plate 2 and an accordion curtain 3. The room on the left side of the partition plate 2 is a storage room, in which various equipment and outdoor units (not shown) of air conditioners 41 to 43 described later are arranged. Ability to open door 4 to enter the storage room During practice, door 4 is closed. In the center room, a compression training area A and a pump training area B are provided. The room on the right side of the accordion curtain 3 is the lighting practice area C.

[0016] A compressor 10 is arranged at a position adjacent to the partition plate 2 in the compression training area A. The The compressor 10 is a facility that simulates an air compressor that can be arranged in a factory or an actual facility such as a warehouse or a store having a refrigerator. An output port of the compressor 10 is connected to a flow meter 11 and a compression training facility 12 via a pipe (not shown). Since air compressed by a general compressor has pulsation, in actual facilities, compressed air is often guided to a large-capacity receiver tank to attenuate pressure pulsation. The training system 100 needs to be accommodated in the limited space of the container 1. Therefore, in the energy-saving training system 100, the compressor 10 is controlled so that the pulsation of the compressed air is not generated by the inverter.

[0017] The compression training facility 12 is provided with air tanks 121 and 122 and a pressure gauge for each tank. Tanks 121 and 122 are simulated receiver tanks and have a small power capacity and a weak function of damping pressure pulsation. The tanks 121 and 122 can be connected to the output port of the compressor 10 with hoses having different shapes, and the difference in air pressure loss due to the difference in hose shape can be measured with a pressure gauge. ing. In addition, casters are provided below the compression training equipment 12 so that the compression training equipment 12 can move inside the container 1. Thus, the narrow space in the container 1 can be effectively used.

[0018] In the compression training area A, an electric control panel 13 for compressed air training equipment is further arranged. The electric control panel 13 for compressed air training equipment is provided with a power meter and is consumed by the compressor 10. The power can be measured. As a power source of the compressor 10, for example, an induction motor driven by a three-phase AC power supply can be used. The above-mentioned inverter for controlling the compressor 10 is provided in the compressed air training facility electric control panel 13 so that the rotation speed and the like of the induction motor can be controlled. The trainee uses the compressed air training facility electric control panel 13 to control the number of revolutions by the inverter under various conditions and to measure the power consumed in the compressor 10. In this way, trainees can confirm the effects of various energy conservation measures. Since this training facility is provided with the compressor 10 simulating an actual machine, the trainee can learn various measures effective for energy saving while actually operating the compressor 10.

[0019] The pump training area B includes a pump 20, a water tank 21, and a pump training equipment electric control panel 22. Is provided. The pump 20 is a facility that simulates a water supply pump that can be arranged in actual facilities such as factories, office buildings, warehouses, and stores. The pump 20 is provided with an induction motor, and its rotation speed can be controlled. The output port of the pump 20 is connected to a switching valve so as to be selectively connectable to a plurality of pipes having different diameters. In addition, each pipe is equipped with a measuring device that can measure pressure loss, and in pump training area B, it is possible to practice pressure loss due to differences in pipe diameter.

[0020] In general, the smaller the pipe diameter is, the longer the pipe length is, and the larger the pressure loss is. However, the length of the piping installed in Container 1 must be shortened due to space restrictions. The difference in pressure loss is difficult to understand. Therefore, by installing a flow control valve in the middle of each pipe and adjusting the opening of the flow control valve, a pressure loss equivalent to the pressure loss that occurs in a pipe with a pipe length longer than the true pipe length is simulated. Producing. Here, the opening degree of the flow control valve may be adjusted directly by the trainee, or may be adjusted by air drive or electric drive.

The electric power control panel 22 for the pump training equipment incorporates a power meter, an inverter for driving the induction motor of the pump 20, and a PID (Proportional, Integral, Differentiate) control device. Applications of PID control include flow control, pressure control, and the like. In this training facility, it is possible to practice power saving measures combining flow control and pressure control, and it is possible to control the opening of the flow control valve in the piping and the rotation speed of the induction motor by the inverter.

The graph (A) in FIG. 2 shows the relationship between the flow rate and the pressure when the flow rate is controlled by the flow rate adjusting valve so as to match the required flow rate. When the control is on, the flow rate is constant, but the pressure rises.

[0023] A graph (B) in Fig. 2 shows a state in which the pressure control by the inverter is performed. In this case, the pressure can be kept constant while the control is on, but the flow rate fluctuates.

The graph (C) in FIG. 2 shows the relationship between the flow rate and the pressure when the flow rate control by adjusting the opening of the flow rate control valve and the pressure control by the inverter are performed simultaneously. In this case, the flow rate is appropriately controlled, and the inverter control is performed so that the rotation speed of the induction motor is reduced by the rotation speed corresponding to the pressure increase due to the decrease in the flow rate. As a result, power corresponding to the pressure change is not wasted and power is saved. [0025] The power consumption of the pump in each of the on and off states of the flow rate control and / or the pressure control can be measured by a power meter provided in the pump training facility electric control panel 22. As described above, in the pump training area B, the trainees measured the power consumed by the pump 20 under various conditions using the pump 20, and confirmed the effects of various energy saving measures. I do.

[0026] In the lighting training area C, a plurality of lighting devices 30 and a lighting electrical control panel 31 are provided. As will be described later, the lighting electric control panel 31 has a power meter. The lighting device 30 is a facility that simulates a lighting device in an actual facility such as a factory, an office building, a warehouse, a store, and the like.

[0027] As the lighting device 30 provided in the lighting training area C, there is an inverter-controlled fluorescent lighting device in addition to a general fluorescent lighting device, and different types of fluorescent lighting devices under the same illuminance are used. The difference in power consumption can be measured with a wattmeter. In addition, there are two types of fluorescent lamp devices, one with a magnetic ballast and the other with an electronic ballast, so that the effect of power saving measures due to the difference in ballast type can be measured with a wattmeter. It has become.

[0028] These lighting devices 30 are partitioned by a set of two curtains, and for example, it is possible to measure and compare the illuminance in the sections with a portable illuminometer. Also, the curtain set used for the partition has a black curtain and a white curtain, and the color of the curtain around each lighting device 30 (which can correspond to a wall in actual equipment) is switched between white and black. Can be done. Apprentices can learn the relationship between wall color and illuminance and power consumption by measuring the illuminance due to the difference in wall color.

[0029] The lighting electric control panel 31 is provided with a power meter, a voltage adjustment dial, a power supply frequency switching switch, a human feeling control unit, an illuminance control unit, and the like. The wattmeter measures and displays the power consumed by the lighting device 30. The voltage adjustment dial is an operation member for adjusting the voltage supplied to the lighting device 30, and when the trainee operates the voltage adjustment dial, the power supply voltage is changed according to the operation amount. Therefore, trainees can learn that lowering the power supply voltage contributes to power saving.

[0030] The power supply frequency switching switch is used to switch the frequency of the magnetic ballast, for example, from 50 Hz to 60 Hz or vice versa. The system is housed in Container 1 It is possible to travel to various parts of the world and practice energy saving. The frequency of commercial power is 60 Hz in some countries or regions, while it may be 50 Hz in other countries or regions. By switching the frequency of the magnetic ballast using the power supply frequency switch, accurate power measurement can be performed.

[0031] The motion control unit includes a motion sensor, a motion sensor switch, and a control device. The motion sensor switch is used to switch on and off the energy saving control by the motion sensor, and outputs a signal corresponding to the operation of the trainee. The control device executes the control when the motion sensor switch is on, but does not execute the control when the motion sensor switch is off.

[0032] The human sensor detects that a human is within a predetermined range and outputs a detection signal. The human sensor is, for example, an infrared sensor, and outputs a detection signal based on a change in the measured amount of infrared light. The detection signal goes high when there is a human, and goes low when there is no human. The control device supplies power to the lighting device 30 while the detection signal is at a high level, and does not supply power to the lighting device 30 while the detection signal is at a low level. Therefore, power is consumed only when there is a human in the vicinity of the lighting device 30, and power is not consumed when lighting is not required. The trainee can operate the motion sensor switch to check the effect of energy saving measures by the motion control unit.

[0033] The illuminance control unit includes an illuminance sensor, an illuminance sensor switch, and a control device. The illuminance sensor switch is used to switch on and off the energy saving control by the illuminance sensor, and outputs a signal according to the trainee's operation. The control device executes the control when the illuminance sensor switch is on, but does not execute the control when the illuminance sensor switch is off.

The illuminance sensor measures the surrounding illuminance and outputs a detection signal according to the measurement result. The detection signal goes high when the measured value falls below a predetermined reference value, and goes low when the measured value exceeds the reference value. The control device supplies power to the lighting device 30 while the detection signal is at a high level, but does not supply power to the lighting device 30 while the detection signal is at a low level. Therefore, power is consumed only when the surroundings of the lighting device 30 become dark and fall below the reference illuminance, and when no illumination is required, power is not consumed. Real Trainees can operate the illuminance sensor switch to check the effect of energy saving measures by the illuminance control unit.

As described above, in the lighting training area C, the trainee uses the lighting device 30 to measure the power consumed in the lighting device 30 under various conditions, and confirms the effects of various energy saving measures.

[0036] Air conditioners 41, 42, and 43 are provided in the container 1, and these air conditioners operate to maintain a comfortable environment when trainees practice. In addition, temperature and humidity sensors are provided at six locations inside the container 1, so that it is possible to practice temperature and humidity changes by adjusting the air conditioning outlet and optimizing the flow rate adjustment. A power supply box 50 is provided in the center room. The power supply box 50 is a device for supplying power to each facility, and is provided with a power meter 51 for measuring the total power of the entire facility, a consumption monitoring device 52, and the like.

FIG. 3 is a block diagram showing an electrical configuration of the energy saving training system 100.

The energy-saving training system 100 is supplied with a 3-phase 220V AC voltage at a frequency of 50Hz or 60Hz from an external power supply via power supply terminals XI, X2, and X3. Power supply terminals XI, X2, X3 are connected to power lines R, S, and T. Power supply lines R, S, and T are provided with breakers 60-72. Each breaker 60-72 releases the connection state when the current value exceeds a predetermined value.

[0038] A three-phase AC voltage is supplied to the pump training facility electric control panel 22 and the compressed air training facility electrical control panel 13 via power supply wirings S and T. Further, a transformer 73 is connected to the power supply lines R and S, and the transformer 73 converts a 220V AC voltage into a 110V AC voltage. The lighting electric control panel 31 is supplied with an AC voltage of 110 V converted by the transformer 73. Further, a two-phase AC voltage is supplied to the air-conditioning electric equipment control panel 45 via the power supply wirings S and T. The air-conditioning electric equipment control panel 45 is omitted in FIG.

The power meter 51 is connected to the power supply wirings R, S, and T via a fuse 8082, measures the voltages thereof, and uses the current transformers 83 and 84 to supply the power supply wirings R and S. Measure the current flowing through Τ. These measurement points are indicated by the power wiring R, S, and T in each control panel. It is provided in the main part before branching. Therefore, the wattmeter 51 can measure the total power consumed by the energy saving training system 100 based on the detected voltage and current. The wattmeter 51 displays the instantaneous value of the power and outputs a number of pulses corresponding to the power consumption (kWh) to the consumption monitoring device 52 as a power indication signal. That is, the power meter 51 outputs a predetermined number (for example, one) of pulses to the consumption monitoring device 52 as a power amount instruction signal every time a unit power amount (for example, 0.1kwh) is consumed.

It is important to monitor the power consumption per unit time so as not to exceed the threshold from the viewpoint of reducing the power consumption over a longer period. In addition, some power supply companies may set the basic fee paid by the facility based on the maximum amount of power consumption per unit time (for example, 30 minutes) or the average power consumption per year. The basic fee set by such a system may not be reduced in principle for one year. Therefore, in such a system, it is particularly important to monitor the power consumption so that it does not exceed the threshold.

[0041] The consumption monitoring device 52 counts the pulses of the power consumption instruction signal, and performs an operation of monitoring the power consumption per unit time (consumption monitoring period). The alarm device 53 generates an alarm sound based on a control signal output from the consumption monitoring device 52. The cutoff device 54 cuts off the power supplied to the air conditioners 41 to 43 based on the control signal output from the consumption monitoring device 52.

[0042] The consumption monitoring device 52 includes a timer. This timer starts at 29:59, counts down every second until 00:00:00, and returns to 29:59 again at 00:00:00. Therefore, the consumption monitoring period is 30 minutes from 29:59 to the next 29:59. Note that the timer operates in synchronization with the power supply frequency.

[0043] The consumption monitoring device 52 has a function of displaying the current power consumption P. The current power consumption P means the power consumption from the start of the consumption monitoring period to the present. The power consumption monitoring device 52 counts the number of pulses of the power amount instruction signal output from the power meter 51 from the start of the power consumption monitoring period, and multiplies the counted value by the pulse conversion ratio to calculate the current power consumption P. Is calculated. The noise conversion ratio is the power consumption per pulse (for example, 0.1kwh / pulse). [0044] The consumption monitoring device 52 stores a predetermined target power consumption Q or a target power consumption Q input by a trainee. The target power consumption Q corresponds to the contracted power and means the allowable upper limit of the power consumed in 30 minutes. Further, the consumption monitoring device 52 calculates the predicted power consumption R and the necessary adjustment power U according to the following formula.

[0045] R = P + (30-t) X ΔΡ / At

U = (Q-R) X 30 / (30-t)

However, At is a minute unit time for pulse counting.Specifically, the starting force of the consumption monitoring period is 3 minutes until 27 minutes (remaining time 3 minutes), and the remaining time 3 minutes is also until the end of the consumption monitoring period. Is one minute. ΔΡ is the increment of power consumption in the minute unit time At, and t is the elapsed time from the start of the consumption monitoring period. The predicted power consumption R is the power consumption after the consumption monitoring period elapses, that is, 30 minutes later, predicted from the change in the current power consumption. The required adjusted power U corresponds to the power to be saved within the remaining time if the predicted power R exceeds the target power Q.

Further, the consumption monitoring device 52 activates a predicted value-based alarm, a current value-based alarm, and a required adjustment value-based alarm under predetermined conditions. The predicted value based alarm is generated when the predicted power consumption R exceeds the target power consumption Q. The consumption monitoring device 52 controls the alarm device 53 so as to sound a buzzer for 10 seconds as a predicted value reference alarm. The predicted value based alarm is released when the predicted power consumption R falls below the target power consumption Q.

[0047] The current value-based alarm is activated when the current power consumption P is equal to or greater than the current value-based alarm threshold and the current power consumption P exceeds the ideal power consumption characteristic Y. The ideal power consumption characteristic Y is given by Y = tX Q / 30 (see Fig. 4). The consumption monitoring device 52 controls the alarm device 53 so as to sound a buzzer continuously as a current value reference alarm. Current value The reference alarm is released when the current power consumption P falls below the ideal power consumption characteristic Y.

[0048] The necessary adjustment value reference alarm is activated when the absolute value of the required adjustment power amount U becomes equal to or greater than the necessary adjustment value reference alarm threshold value. The consumption monitoring device 52 controls the alarm device 53 so that a buzzer is continuously sounded as a necessary adjustment value reference alarm. The required adjustment value reference alarm is released when the absolute value of the required adjustment power amount U falls below the required adjustment value reference alarm threshold. Also, The consumption monitoring device 52 controls the shutoff device 54 so as to shut off the power of the air conditioners 41 to 43 in accordance with the activation of the predicted value reference alarm, the current value reference alarm, and the necessary adjustment value reference alarm.

Next, the operation of the consumption monitoring device 52 will be described with reference to an example of consumption monitoring shown in FIG. The ideal power consumption characteristic Y shown by a dashed line in the figure shows an example where the power consumption linearly reaches the target power consumption Q (Y = t X Q / 30). Let Z be the actual power consumption characteristic. In this example, at time tl, since the predicted power consumption exceeds the target power consumption Q, the predicted value based alarm is activated. Then, at time t2, when the required adjustment power amount U becomes equal to or greater than the required adjustment value reference alarm threshold, the required adjustment value reference alarm is activated. Further, at time t3, when the current power consumption P becomes equal to or more than the current value reference alarm value, the current value reference alarm is activated.

[0050] With the activation of these alarms, an alarm sound is generated and the air conditioners 41 to 43 stop operating. Thus, the trainee can feel various warnings. The power consumption monitoring device 52 controls the alarm device 53 so as to emit an alarm sound when the predicted value reference alarm is activated, and thereafter, the current power consumption P becomes the current value reference alarm threshold. When the predetermined condition is satisfied, the shutoff device 54 may be controlled so as to shut off the power supply of the air conditioners 41 to 43. In this case, the trainees can be notified step by step that the possibility of exceeding the target power consumption has increased.

Further, the device to be stopped when the predetermined condition is satisfied may be another specific device housed in the container 1 including the pump 20, the compressor 10, or the lighting device 30. However, if the pump 20, the compressor 10, or the lighting device 30 is to be stopped, energy saving training cannot be performed. Therefore, it is preferable to stop auxiliary devices such as the air conditioners 41 to 43.

[0052] In addition, an adjustment device that adjusts the power instead of the cutoff device 54 may be used to control so as to reduce the electric load of the specific device. For example, when the specific device is an air conditioner 41-43, control may be performed so as to reduce the amount of air blown. In this way, by lowering the electrical load on specific equipment, the trainee can realize that it is necessary to reduce the electrical load and take energy-saving measures so as not to exceed the target power consumption Q.

[0053] The energy-saving training system 100 described above simulates equipment in an actual facility. It includes a pump 20, a compressor 10, and a lighting device 30. These devices account for most of the power consumption in actual facilities. Therefore, by conducting practical training on energy conservation measures using these devices, trainees can effectively acquire knowledge on energy conservation that is useful in the field. In addition, since power consumption monitoring is performed based on the amount of power consumed by these training facilities, it is possible to practice the effects of various combinations of energy saving measures implemented in each facility, and to practice comprehensive energy saving measures. It becomes possible.

Although the present invention has been illustrated and described in detail with reference to the preferred embodiments, various modifications in form and detail can be made within the spirit and scope of the invention described in the claims. Those skilled in the art will understand that various modifications are possible. Applicants intend that such changes, alternatives, and modifications also fall within the scope of the invention.

For example, in the above embodiment, the power consumption per unit time is monitored. However, monitoring the average power consumption per unit time is equivalent to the embodiment, and is included in the scope of the present invention. It is.
