Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an energy saving training system capable of practicing energy saving in an office.
[0002]
[Prior art]
Under recent circumstances where there are concerns about the environmental impact of carbon dioxide emissions, there is a need to reduce the amount of energy used at business sites. In response, the law on the rational use of energy was revised in 2002. Under the revised law, it is obliged to rationalize the use of energy for offices such as buildings, hotels, schools, and hospitals. The offices are equipped with various types of electricity use facilities, and the power consumed by these facilities becomes a problem.
[0003]
[Problems to be solved by the invention]
Energy saving measures at business establishments such as buildings are important from the viewpoint of cost reduction and legal compliance, and various measures have been proposed. However, there is no known system that allows the manager to practice while simulating energy usage and experiencing the effects of energy saving on various measures.
[0004]
Then, this invention makes it a solution subject to provide the energy-saving training system which can practice the energy-saving measure by simulating the usage condition of the energy in an establishment.
[0005]
[Means for Solving the Problems]
The energy-saving training system according to the present invention is an energy-saving training system (100) for practicing energy-saving measures at an office, and means for changing the operating conditions of the pump according to the operation of the pump (20) and the trainee ( 22), a pump training facility (B) comprising a means (22) for presenting to the trainee a change in power consumption of the pump accompanying a change in the operating conditions, a compressor (10), and the training Means (13) for changing the operating condition of the compressor (10) according to a raw operation, and means (13) for presenting the trainee with a change in power consumption of the compressor accompanying the change in the operating condition. By means of a compressor training facility (A), a lighting device (30), means (31) for changing the usage status of the lighting device in accordance with the operation of the trainee, and a change in the usage status Expenses and illumination device training equipment changes in power and means (31) to be presented to the trainee (C), by comprising a, for solving the above problems (claim 1).
[0006]
Most of the electric power in an actual office is consumed by pump equipment, compressor equipment, and lighting equipment. According to the present invention, the operating condition such as the driving condition and the usage status is changed according to the operation of the trainee, and the change in the power consumption accompanying the change is presented. Therefore, the trainee has an effect on the predetermined energy saving measure. It is possible to confirm. Thereby, the trainee can effectively practice the measures necessary for energy saving in the office through the actual operation of the equipment.
[0007]
This energy-saving training system is preferably accommodated in a transportable container (claim 2). In this case, by connecting the container and the vehicle and moving, it is possible to go to a facility such as a factory and practice energy saving measures.
Moreover, in the energy-saving training system mentioned above, the total electric power supplied to the said pump training equipment (B), the said compressor training equipment (A), and the said illuminating device training equipment (C) is detected, Based on a detection result It is preferable to provide a demand monitoring facility (51, 52, 53, 54) for monitoring the demand (Claim 3).
[0008]
According to the present invention, since the total power consumed in each simulated facility is detected and the demand is monitored, not only the individual energy saving measures but also the demand that is the total amount of power is practiced. be able to. In other words, how energy saving measures for pump equipment affect demand, or energy saving measures for each equipment, such as the effect of reducing demand by combining energy saving measures for compressor equipment and energy saving measures for lighting equipment. It is possible to experience the combined effects in a single system, and practice comprehensive energy saving measures.
[0009]
The above-described demand monitoring equipment (51, 52, 53, 54) predicts a demand when a predetermined time has elapsed from the start of monitoring based on the demand monitoring result, and the predicted demand exceeds the predetermined demand It is preferable that an alarm be activated.
[0010]
The basic charge according to the contracted power among the electricity charges at the office is determined by the maximum amount of power for a predetermined time (30 minutes) throughout the year. Therefore, it is important to monitor the maximum usage amount so as not to exceed the contract power from the viewpoint of reducing the electricity bill. According to this invention, based on the demand monitoring result, the demand at the time when a predetermined time has elapsed from the start of monitoring is predicted, and an alarm is activated when the demand exceeds the predetermined demand. As a result, it is possible to inform the trainee that the amount of power will exceed if the current operating state of the equipment continues. In this case, the trainee can learn what measures are effective so as not to exceed the contract power by executing energy saving measures in each simulated facility.
[0011]
Preferably, the demand monitoring facility (51, 52, 53, 54) executes control to lower the electrical load of the specific device when a predetermined condition is further satisfied after the alarm is activated (Claim 4).
[0012]
According to the present invention, since the electrical load of the specific device is lowered when a predetermined condition is further satisfied after the alarm is activated, the trainee can obtain the demand monitoring result by the change in the operation status of the specific device. Can be learned. Lowering the electric load includes stopping power supply to the specific device and reducing power consumed by the specific device. For example, in the case where the specific device is an air conditioner, a process for reducing the air flow rate is included. The specific device is preferably an auxiliary device that is provided separately from the pump training facility, the compressor training facility, and the lighting device training facility and operates during the training. In this case, the electrical load of the auxiliary equipment is automatically reduced, but the control targets are auxiliary equipment provided separately from the pump training equipment, compressor training equipment, and lighting training equipment. This is not the target facility itself for the main training. Therefore, the main training itself is not interrupted, and the training can proceed smoothly.
[0013]
Another energy-saving training system according to the present invention is a system for practicing energy-saving measures at an office, wherein the pump (20), a plurality of pipes having different diameters, and the plurality of pipes are selectively used as the pump. A connecting means for connecting to the measuring means, a measuring means (22) capable of measuring the pressure loss of the pipe connected by the connecting means,
By providing a flow rate adjusting valve provided in the pipe so that the pressure loss obtained when the pipe length is longer than the actual pipe length can be simulated by adjusting the opening degree, the above-mentioned problems are solved. (Claim 6).
[0014]
If a pipe of the same length as the pipe connected to the pump in an actual office is incorporated in the training system, the training system will be enlarged. On the other hand, the pressure loss of the pipe increases as the pipe length increases. According to this invention, in order to obtain the pressure loss obtained when the pipe length is longer than the actual pipe length, the flow control valve is provided in the training pipe. By adjusting the opening of the flow rate adjusting valve, pressure loss can be simulated, and the training system can be downsized. This is particularly useful when the energy saving training system is accommodated in a container.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1, the top view of the energy saving training system which concerns on one Embodiment of this invention is shown. The energy saving training system 100 is accommodated in a container 1 that can be moved by a vehicle. The container 1 is provided with a door 1a and a door 1b. The door 1a opens from the upper part of the container 1 toward the outside. In the opened state, the door 1a and the floor of the container 1 are connected to each other without a step, and serve as an entrance for the trainee to enter the training system.
[0016]
The interior of the container 1 is 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 fixtures and outdoor units (not shown) of the air conditioners 41 to 44 are arranged. You can enter the storage room with the door 4 open, but the door 4 is closed during the practice. A compression training area A and a pump training area B are provided in the central room. The room on the right side of the accordion curtain 3 is a lighting training area C.
[0017]
In the compression training area A, the compressor 10 is disposed along the partition plate 2. The compressor 10 is a facility that simulates a compressor (compressor) disposed in an actual office. The compressor 10 compresses air, and is connected to the flow meter 11 and the compression training facility 12 via a pipe (not shown). Since the air compressed by the compressor 10 has pulsation, in actual offices, the compressed air is often guided to the receiver tank to attenuate the pressure pulsation. However, the energy saving training system 100 needs to be accommodated in a limited space of the container 1. Therefore, an inverter is provided in the compressed air training facility electrical control panel 13 to control the compressor 10 so that compressed air pulsation does not occur.
[0018]
The compression training facility 12 is provided with tanks 121 and 122. The tanks 121 and 122 are connected by hoses having different shapes, and the difference in air pressure loss due to the difference in the shape of the hose can be measured. In addition, a caster is provided in the lower part of the compression training facility 12 so that the inside of the container 1 can be moved. Thereby, a narrow space can be used effectively.
[0019]
The compressed air training facility electrical control panel 13 is provided with a wattmeter so that the power consumed by the compressor 10 can be measured. As a power source of the compressor 10, for example, an induction motor driven by a three-phase AC power source can be used. The compressed air training equipment electrical control panel 13 is provided with an inverter for controlling the compressor 10 so that the number of revolutions of the induction motor can be controlled. The trainee uses the compressed air training facility 12 to control the rotation speed by the inverter under various conditions and measure the power consumed in the compressor 10. Thereby, the trainee can confirm the effect of various energy saving measures. Since this training facility includes the compressor 10 as an actual machine, the trainee can learn various measures effective for energy saving while actually operating the compressor 10.
[0020]
In the pump training area B, a pump 20, a water tank 21, and a pump training facility electrical control panel 22 are provided. The pump 20 is a facility that simulates a pump disposed in an actual office. The pump 20 includes an induction motor, and the number of rotations thereof can be controlled. The pump 20 is connected to a device that can be selectively coupled to a plurality of pipes having different diameters. In addition, a measuring device capable of measuring pressure loss is provided, and in pump training area B, pressure loss due to a difference in pipe diameter can be practiced. In general, the smaller the pipe diameter and the longer the pipe length, the greater the pressure loss. However, since the piping incorporated in the container 1 is limited in space and the length of the piping must be shortened, the difference in pressure loss is difficult to understand. Therefore, each pipe is provided with a flow rate adjustment valve, and the pressure loss is created in a pseudo manner by adjusting the opening of the flow rate adjustment valve. Here, the opening degree of the flow rate adjustment valve may be adjusted directly by the trainee, or may be adjusted by air drive or electric drive.
[0021]
The pump training facility electrical control panel 22 incorporates a power meter, an inverter for driving the pump 20, and a PID control device. Applications of PID control include flow rate control and pressure control. In this training facility, power saving measures combining flow control and pressure control can be practiced, and the opening of the flow control valve and the rotation speed of the induction motor by the inverter can be controlled.
[0022]
FIG. 2 (A) shows the relationship between the flow rate and the pressure when the flow rate is controlled in accordance with the requirements of the supply destination. In the control-on state, the flow rate is constant, but the pressure increases. FIG. 2B shows a state in which pressure control by an inverter is executed. In this case, the pressure can be kept constant while the control is on, but the flow rate varies. FIG. 2C 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 executed simultaneously. In this case, the flow rate is appropriately controlled, and the inverter control is executed so as to decrease the number of rotations corresponding to the pressure increase accompanying the decrease in the flow rate. As a result, power corresponding to the pressure change is not wasted and power saving is achieved. Thus, in the pump training area B, the trainee uses the pump 20 to measure the power consumed in the pump 20 under various conditions, and confirms the effects of various energy saving measures.
[0023]
In the lighting training area C, a plurality of lighting devices 30 and a lighting electric control panel 31 are provided. The lighting device 30 is a facility that simulates a lighting device in an actual office. As the lighting device 30, there is an inverter-controlled fluorescent lamp device in addition to a general fluorescent lamp device, and the difference in power consumption at the same illuminance can be measured. Furthermore, the fluorescent lamp device is provided with a magnetic ballast and an electronic ballast, and the power saving effect due to the difference between the ballasts can be measured. These illumination devices 30 are partitioned by two sets of curtains, and can be measured by comparing illuminance. Moreover, the group of the curtain used for a partition is arrange | positioned by the black curtain and the white curtain, and can switch the color of a wall (curtain) with white and black. The trainee can learn power saving by measuring the illuminance due to the difference in wall color.
[0024]
The illumination electrical control panel 31 is provided with a power meter, a voltage adjustment dial, a power frequency switching switch, a human presence 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 illumination device 30. When the trainee operates the voltage adjustment dial, the power supply voltage is changed according to the operation amount. Accordingly, the trainee can learn that lowering the power supply voltage contributes to power saving.
[0025]
The power frequency switch is used to switch the frequency of the magnetic ballast at 50 Hz / 60 Hz. This system is housed in a container 1 and can travel to various parts of the country to practice energy conservation. The frequency of the commercial power source is 60 Hz in the Kansai region, whereas it is 50 Hz in the Kanto region. By switching between 50 Hz / 60 Hz with the power frequency switching switch, it is possible to measure accurate power.
[0026]
The motion control unit includes a motion sensor, a motion sensor switch, and a control device. The human sensor switch is used to switch on / off the energy saving control by the human sensor, and outputs a signal corresponding to the operation of the trainee. The control device executes control when the human sensor switch is in the on state, but does not execute control when the human sensor switch is in the off state. The human sensor detects the presence of a person within a predetermined range and outputs a detection signal. The detection signal is at a high level when there is a person and at a low level when there is no person. 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 there is a person around the lighting device 30, and power is not consumed when illumination is not necessary. The trainee can operate the human sensor switch to confirm the effect of energy saving measures by the human motion control unit.
[0027]
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 / off the energy saving control by the illuminance sensor, and outputs a signal corresponding to the operation of the trainee. The control device executes control when the illuminance sensor switch is in the on state, but does not execute control when the illuminance sensor switch is in the off state. The illuminance sensor measures ambient illuminance and outputs a detection signal corresponding to the measurement result. The detection signal becomes a high level when the measured value falls below a predetermined reference value, and becomes a low level 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 falls below the standard illuminance, and power is not consumed when illumination is not necessary. The trainee can operate the illuminance sensor switch to confirm the effect of energy saving measures by the illuminance control unit.
[0028]
Thus, 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 confirm the effects of various energy saving measures.
[0029]
The container 1 is provided with air conditioners 41, 42, and 43, which operate when the trainees practice and maintain a comfortable environment. In addition, temperature / humidity sensors are provided at six locations inside the container 1, and power saving can be practiced by adjusting the air-conditioning outlet and optimizing the flow rate. A power supply box 50 is provided in the central room. The power supply box 50 is a device that supplies power to each facility, and is provided with a power meter 51 and a demand monitoring device 52 that measure the total power of the entire facility.
[0030]
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 three-phase 220 V AC voltage from an external power supply via power supply terminals X1, X2, and X3. The power supply terminals X1, X2, and X3 are connected to power supply lines R, S, and T. Breakers 60 to 72 are provided in the power supply wirings R, S, and T. Each breaker 60-72 will open a connection state, if an electric current value exceeds predetermined value. A three-phase AC voltage is supplied to the pump training facility electrical control panel 22 and the compressed air training facility electrical control panel 13 via power wirings R, 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 illumination electric control panel 31 is supplied with 110V AC voltage converted by the transformer 73. Further, the two-phase AC voltage is supplied to the air conditioning electrical equipment control panel 45 via the power supply wires S and T. Although the air conditioning electrical equipment control panel 45 is omitted in FIG. 1, for example, it may be arranged in the storage room on the left side of the partition plate 2.
[0031]
The wattmeter 51 is connected to the power supply wirings R, S, and T via the fuses 80 to 82, measures the voltages thereof, and is connected to the power supply wirings R and T by the instrument current transformers 83 and 84. Measure the flowing current. These measurement points are provided in the basic part before the power supply wirings R, S, and T branch to each control panel. 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 an instantaneous value of power and outputs a predetermined number of pulses per unit power (kwh) to the demand monitoring device 52 as a power instruction signal.
[0032]
The electricity charge is determined by the sum of the basic charge according to the contracted power and the usage charge according to the amount of power actually used. The contract power is determined with a maximum power amount of 30 minutes throughout the year, and the contract power determined in principle cannot be reduced for one year. For example, if the maximum amount of power for 30 minutes exceeds the contract power in July, the basic charge corresponding to the contract power will increase from August, and the contract power after the increase cannot be reduced for one year in principle. Therefore, it is important to monitor so that the maximum usage does not exceed the contract power.
[0033]
The demand monitoring device 52 counts the pulses of the power instruction signal and executes the above-described monitoring operation. The alarm device 53 generates an alarm sound based on the control signal output from the demand monitoring device 52. The shut-off device 54 shuts off the power supplied to the air conditioners 41 to 43 based on the control signal output from the demand monitoring device 52.
[0034]
The demand monitoring device 52 includes a timer. This timer starts from 29 minutes 59 seconds, subtracts every second from 00 minutes 00 seconds, and returns to 29 minutes 59 seconds again. The demand time period is 30 minutes from 29 minutes 59 seconds to the next 29 minutes 59 seconds. Note that the time period operates in synchronization with the power supply frequency.
[0035]
The demand monitoring device 52 has a function of displaying the current demand P. The current demand P means the amount of power from the demand time limit 0 to the present time. The demand monitoring device 52 calculates the current demand P by counting the number of pulses of the power instruction signal output from the wattmeter 51 from the demand time limit 0 and multiplying the counted value by the pulse conversion ratio. The pulse conversion ratio indicates the amount of power per pulse.
[0036]
The demand monitoring device 52 stores a predetermined target demand Q or a target demand Q input by a trainee. The target demand Q corresponds to contract power and means an allowable value of the amount of power consumed for 30 minutes. Furthermore, the demand monitoring apparatus 52 calculates the predicted demand R and the adjusted power U according to the following formula. Is calculated.
R = P + (30−t) × ΔP / Δt
U = (Q−R) × 30 / (30−t)
However, Δt is the pulse integration time, which is 3 minutes from the start of the time limit to the remaining time of 3 minutes, and 1 minute from the remaining time of 3 minutes to the end of the time limit. ΔP is the increase in demand for Δt minutes, and t is the elapsed time of the demand time period. The predicted demand R is a predicted demand from a change in demand after 30 minutes, which is a unit time for demand monitoring.
[0037]
Further, the demand monitoring device 52 issues a prediction alarm, a fixed alarm, and an adjustment alarm under a predetermined condition. The prediction warning is generated when the predicted demand R exceeds the target demand Q. At this time, the demand monitoring device 52 controls the alarm device 53 to sound the buzzer for 10 seconds. The prediction warning is canceled when the predicted demand R becomes equal to or less than the target demand Q. The fixed alarm is activated when the current demand P exceeds the fixed alarm value and the current demand P exceeds the ideal demand characteristic Y. The ideal demand characteristic Y is given by Y = t × Q / 30. At this time, the demand monitoring device 52 controls the alarm device 53 so as to continuously sound the buzzer. The fixed alarm is canceled when the current demand P falls below the ideal demand characteristic Y. The adjustment alarm is activated when the adjustment power U becomes equal to or greater than the adjustment alarm value. At this time, the demand monitoring device 52 controls the alarm device 53 so as to continuously sound the buzzer. The adjustment alarm is canceled when the adjustment power U falls below the adjustment alarm value. Moreover, the demand monitoring apparatus 52 controls the interruption | blocking apparatus 54 so that the power supply of the air conditioners 41-43 may be interrupted | blocked with generation | occurrence | production of a prediction alarm, a fixed alarm, and an adjustment alarm.
[0038]
Next, the operation of the demand monitoring device 52 will be described with reference to the example of demand monitoring shown in FIG. The demand characteristic Y indicated by the alternate long and short dash line in the figure shows an example in which the target demand Q is reached linearly. Let Z be the actual demand characteristic. In this example, since the predicted demand R exceeds the target demand Q at time t1, a prediction alarm is activated. Then, when the adjustment power U becomes equal to or higher than the adjustment alarm value at time t2, the adjustment alarm is activated. Furthermore, when the current demand P becomes equal to or higher than the fixed alarm value at time t3, a fixed alarm is activated.
[0039]
As these alarms are activated, an alarm sound is generated, and the air conditioners 41 to 43 stop operating. Thereby, the trainee can feel various alarms. The demand monitoring device 52 controls the alarm device 53 to generate an alarm sound when a prediction alarm is activated, and further, when the condition of the fixed alarm as a predetermined condition is satisfied, the air conditioner You may make it control the interruption | blocking apparatus 54 so that the power supply of 41-43 may be interrupted | blocked. In this case, the trainee can be notified step by step that the possibility of exceeding the target demand has increased.
[0040]
Moreover, it is good also considering the apparatus made into the object of a stop as the specific apparatus accommodated in the container 1 containing the pump 20, the compressor 10, or the illuminating device 30. FIG. However, if assigned to the pump 20, the compressor 10, or the lighting device 30, energy saving training cannot be performed. Therefore, it is preferable to assign to auxiliary equipment such as the air conditioners 41 to 43. In addition, an adjustment device that adjusts the power instead of the shut-off device 54 may be used to control the electrical load of the specific device to be reduced. For example, when the specific equipment is the air conditioners 41 to 43, control may be performed so as to reduce the air flow rate. Thus, since the demand can be reduced by lowering the electrical load of the specific device, the trainee learns that it is necessary to take energy saving measures so as not to exceed the target demand Q by reducing the electrical load. be able to.
[0041]
The energy-saving training system 100 described above includes a pump 20, a compressor 10, and a lighting device 30 that simulate facilities in a business office. These devices account for the majority of power consumption in actual offices. Therefore, by performing practical training on energy saving measures using these devices, the trainee can effectively acquire knowledge on energy saving useful in the field. In addition, because demand monitoring is performed based on the amount of power consumed by these training facilities, it is possible to practice the effects of combining various energy saving measures implemented at each facility, and to practice comprehensive energy saving measures It becomes.
[0042]
