Detailed ways

FIG. 1 shows a schematic diagram of a power management system according to a preferred embodiment of the present invention. According to a preferred embodiment, the electricity consumption control system 100 includes: a module 101 for setting a target energy saving amount or electricity degree, a simulation analysis module 102 and an electricity consumption control module 103 . The power consumption control module 103 also includes seven management modules, namely the dynamic temperature management module 1031, the operation schedule management module 1032, the idle space management module 1033, the external air introduction management module 1034, the heat source monitoring management module 1035, the real-time Leakage Management Module 1036 and System Efficiency Management Module 1037 . It should be noted that in other embodiments, other management modules with different functions can also be added according to different control and management systems. According to the historical, real-time and forecast information, the present invention can help the user to precisely allocate the electricity consumption of the air conditioner in each period, so that the user can set the expected amount of electricity consumption per month, quarterly or one year. When air-conditioning power consumption is budgeted, the computer will linearly adjust the parameters of the system-side and load-side air-conditioning facilities according to the load priority, and even adjust the comfort of the load, etc., to prevent the power consumption of the air-conditioning from exceeding the user's expected amount.

According to an embodiment of the present invention, the module 101 for setting a target energy-saving amount or electricity consumption is mainly used to provide a user-set target energy-saving amount or electricity consumption. For example, for a corporate user, electricity consumption or the amount of electricity consumption is also a part of cost control. A reduction in electricity consumption or amount of electricity consumption can indirectly increase profits or reduce the price of terminal products and increase competition. The enterprise user can conduct an actuarial calculation in advance of a unit period, such as a quarter or a month, to determine the reasonable electricity consumption or electricity consumption cost, and use the energy-saving amount or the energy-saving module 101 of the present invention to convert this The reasonable power consumption degree or power consumption is set in the power consumption control module 103 . At this time, the power consumption control module 103 will dynamically monitor the power consumption structure of the enterprise user in a unit cycle according to the set power consumption degree or power consumption budget through its seven management modules. Adjust allocation. Using the pre-term electricity budget control, the electricity consumption can be allocated in the most reasonable way and the waste of electricity consumption can be avoided.

In addition, before the power consumption control and management module 103 starts to execute, it will first conduct a simulation of power consumption control through the simulation analysis module 102, and present the power consumption structure in advance, so that users can know the power consumption degree or Under the power consumption budget, the planned power consumption structure can be fine-tuned. For example, for an enterprise user, under one unit cycle, the total power consumption set by it is 1000 degrees, the simulation analysis module 102 of the present invention can consider historical power consumption data, environmental variables, such as temperature, humidity, and The business user's scheduling plan during this time period simulates a power consumption structure. For example, the electricity consumption allocation is 1 degree higher than the available power consumption in the morning, and the business user can also respond to this The simulation results are fine-tuned, such as adjusting the available degrees in the morning and afternoon, or adjusting the electricity consumption on a specific day.

The power consumption control and management module 103 of the present invention includes seven management modules. The functions of the seven management modules will be described below by taking the management of the power consumption of an air conditioner as an example. In addition, in other embodiments, the seven management modules can also be used to manage other different electrical devices.

The dynamic temperature management module 1031 is mainly used to control the temperature of the air conditioner, and to control the total power consumption by adjusting the set temperature of the air conditioner in real time. The dynamic temperature management module 1031 can adjust the set temperature of the air conditioner at any time according to the target electricity consumption amount set by the user. The set temperature of the air conditioner is the most important factor affecting the operation and comfort of the air conditioner. As different environmental conditions change, it should correspond to different set temperatures so that there will be no excessive use or ineffective operation. The dynamic temperature management module 1031 of the present invention can dynamically adjust the temperature of the air conditioner as the environment changes, taking into account user comfort and efficient use of energy. In addition, if the supply of the air-conditioning system is in short supply due to high thermal load or low set temperature during certain periods of time, causing the compressor (or ice water valve) to continue to open and cannot be closed, the dynamic temperature management module 1031 can automatically adjust to an appropriate temperature. set temperature, or temporarily shut down the compressor (or ice water valve), so that the air conditioning system enters a lower load operating state.

In one embodiment, the management and control program of the dynamic temperature management module 1031 is shown in FIG. 2 , which firstly provides the user with the setting of comfort requirements in units of regions. For example, three levels are provided, "important", "common", and "unimportant", allowing users to set comfort requirements for each area. For example, the office comfort can be set as important, the office comfort can be set as ordinary, and the elevator entrance comfort can be set as unimportant. However, in other embodiments, the required levels of comfort are not limited to three levels. Next, the user defines the priority of comfort level adjustment in each area, for example, it is divided into highest, high, middle, and low levels. Those with low comfort priority will adjust the set temperature first when the energy-saving target threshold cannot be reached; those with medium comfort priority will be the second; Do not change the comfort level or set temperature due to energy-saving requirements. The above adjustment cycle is reset every 15 minutes (adjusted according to the situation).

Then dynamic adjustment can be performed, and the dynamic temperature management module 1031 will calculate the used air-conditioning electricity fee at any time: according to the electricity used by the air-conditioning facility multiplied by the electricity fee per kilowatt-hour of the period (including the average basic electricity fee), the amount accumulated for a period of time. And record the average daily usage time (hours) of the user's air conditioner. This data can be recorded every day as a reference for future adjustments. In addition, the system can also refer to the meteorological unit's forecast of the weather conditions of the day as the basis for retrieving similar weather conditions in the database. Automatically generate the distribution ratio of available electricity charges in each region for each time period of the month, week, and day. The system fills in the target electricity charges desired by the user in 12 months, and the system automatically generates the target electricity charges based on the distribution of electricity consumption ratios in each period of the month, week, and day. Users can also enter each month to adjust the target electricity fee for each week (for example, the target electricity fee for Monday and Saturday may be different), or set the target electricity fee for a specific holiday. In one embodiment, the user can also enter a single day to adjust the target electricity charges for each time period.

For example, the hourly target electricity rate allocation from 7:00 am to 11:00 pm may be different from the hourly target electricity rate allocation from 11:00 am to 2:00 pm. Each hour is divided into 60 equal parts (every 1 minute), which is 1/60. The dynamic energy usage management system accumulates the used electricity charge every 1 minute. If the accumulated electricity charge at that point in time is lower than the target electricity charge, the set temperature will be kept within the standard moderate comfort range, or the set temperature can be set by the user Mainly; if the electricity charge at this point in time exceeds the target electricity charge, the dynamic temperature energy-saving management function will be enabled, and the set temperature on the user side will be raised for the first time by 1 degree Celsius higher than the average return air temperature in the previous 15 minutes and the wind speed will be increased at the same time. If it still cannot be lower than the target electricity rate, then increase the temperature by 0.5 degrees Celsius and so on, up to 30 degrees Celsius to achieve the target electricity rate.

The operation schedule management module 1032 is used to establish a complete air conditioner operation schedule, which saves a lot of waste caused by inaccurate power supply time of switching equipment (such as early opening and delayed closing), and can also take advantage of the cool outdoor air in the middle of the night. The electricity price during the off-peak period, the fan is used to eliminate the indoor heat storage caused by the non-operation of the air conditioner during the holiday, so as to avoid the high electricity cost of using the air conditioner during the peak electricity price period the next day, and replace the heat storage outside the building. For example, when the temperature in the building does not reach the preset temperature at 7 o'clock in the morning, the operation schedule management module 1032 can first turn on the air conditioner to cool down before 7:25, turn off the air conditioner at 7:25, and then turn on the air conditioner during working hours, so that there is no need Consumes excess cooling capacity to discharge heat storage. For buildings with an external air introduction system, the operation scheduling management module 1032 can also introduce fresh and low-temperature outdoor air in the middle of the night or early in the morning. It does not need to turn on the air conditioner to achieve the effect of eliminating the building’s overnight heat storage, so that Users can enjoy a comfortable and pleasant temperature as soon as they enter the office, and there will be no phenomenon that "the user sets the temperature of the air conditioner to the lowest level early in the morning, but no one adjusts it back after a whole day", which saves a lot of trouble. necessary electricity. In addition, the operation schedule management can be combined with an electronic calendar system (such as Microsoft Outlook calendar) as the basis for judging the power consumption control strategy. The system can more intelligently assist users to formulate operation schedule settings that meet their comfort and energy-saving needs.

The idle space management module 1033 improves the use efficiency and is the foundation of all energy management. Air-conditioning and lighting facilities are still on when no one is there, accounting for 38% of the waste factors in buildings. In other words, even if the operating efficiency of the system is good, as long as the efficiency of the client is not used, it will still cause unnecessary energy loss. Therefore, "avoiding waste" and "rational operation" can reduce electricity consumption by drastic measures. Independent compartment environments in buildings, such as small offices, meeting rooms, rooms, toilets, etc., or hotel rooms, use mobile sensors to detect whether the environment is idle and no one is using it to determine the operating status of the facility, which can save a lot of unnecessary waste. For example, after the user leaves the office, the mobile sensor can immediately notify the idle space management module 1033 to close the air-conditioning facilities in the environment, or improve the environmental comfort (enthalpy value), change the air-conditioning to the air supply mode, etc.

External air introduction management module 1034, because 27% of the air-conditioning load comes from external air, so the "timely and appropriate" introduction of external air under the dynamic external air changes is of great help to control the electricity consumption of air-conditioning.

In one embodiment, the external air introduction management module 1034 calculates the average value of all temperature sensors in the air-conditioned area every 10 minutes. The enthalpy value is low, and the external air introduction management module 1034 introduces external air. In addition, in order to avoid frequent switching of the switch, it can be set to introduce outside air above 3 degrees, and close the outside air within 2 degrees. When the outdoor temperature is not lower than the average indoor temperature by more than 3 degrees, the outside air is turned off, unless the _CO2 concentration measured by any _CO2 sensor concentration in the corresponding air-conditioned area exceeds the set upper limit. Air, close the external air when it is lower than the lower limit. The upper and lower limits of the concentration of the CO ₂ sensor are preset as follows: there are different settings according to the comfort level defined by the user (the same setting as the dynamic temperature management). For example, "important" means that the external air is turned on at 1200ppm, and the external air is turned off at 1000ppm; "normal" is that the external air is turned on at 1500ppm and turned off at 1200ppm; The external air introduction management module 1034 allows the user to re-input parameters.

Heat source monitoring and management module 1035, the solar radiation heat exchange around the building is also a common transmission loss, so if you can install sunshades outside the building, draw the curtains when the sun is strong, or design wind around the building The loss caused by radiative heat exchange can be reduced by installing curtains or adding air outlets. But the environment is constantly changing dynamically. In a hot climate, the above situation is true. On the contrary, in a cold climate, the glass that was originally a heat source becomes a cold source, and the air conditioner around the building may also be affected by glass and The cooling air conducted by the wall reduces the load. In one embodiment, the heat source monitoring management module 1035 calculates the average value of all the return air temperature sensors of the facility corresponding to the temperature sensor detecting the heat source every 10 minutes, when the reading value of the heat source temperature sensor is higher than the average return air temperature Or below a certain temperature, the state of the facility is changed according to the setting. For example, opening or closing curtains.

The real-time leak management module 1036 is used to determine the operating status of the facility according to whether the environment has leaks, and at the same time issue an alarm to the user. Air conditioning line leaks are the number one item among all causes of energy waste in buildings. Leakage loss may occur between the transmission pipelines or in the user environment, for example, the doors and windows are not closed, resulting in a large loss of cold (warm) air. In one embodiment, the real-time leakage management module 1036 calculates the average value of all the return air temperature sensors of the facility corresponding to the door and window sensors every 10 minutes. If the outdoor temperature is high and the doors and windows are opened for a period of time, an alarm will be issued or the operation of the air conditioner will be changed. status, such as increasing the set temperature or entering the air supply mode, etc.

The main function of the system efficiency management module 1037 is to determine the number of system hosts to be turned on according to the load demand, so that the chilled water hosts can maintain a high-efficiency operation state. Because, if one chilled water host can provide sufficient load demand, there is no need to turn on two chilled water hosts at the same time, which can reduce the considerable operating power of one chilled water host, cooling water pump and cooling water tower. In one embodiment, when there is only one chilled water host on the client side, the system efficiency management module 1037 can set the initial outlet water temperature to 7°C, and adjust the outlet water temperature every 15 minutes, for example, the lowest outlet water temperature is 7°C C, the maximum is 15 degrees C, so that the comfort of the corresponding air-conditioning facility is maintained at the lower limit of the set value. If the usage amount per unit time has exceeded the budget, the priority is to increase the outlet water temperature, and then increase the load-side air conditioner temperature. In another embodiment, if the chilled water hosts of the client are controlled in parallel by two units, the system efficiency management module 1037 can adopt the method of gradually opening, the first one is opened first, and the initial outlet water temperature is set to 7 degrees C, and each Adjust the outlet water temperature every 15 minutes to keep the comfort of the corresponding air-conditioning facility at the lower limit of the set value. When the comfort level cannot be satisfied for more than 30 minutes, the second ice water main unit will be turned on, and the usage amount per unit time must not exceed the budget. The two chilled water hosts are set to 7 degrees C at the same time, and the outlet water temperature of the second chilled water host is adjusted every 15 minutes to maintain the comfort of the corresponding air-conditioning facilities at the lower limit of the set value. When the temperature setting of the second ice water main unit has reached 15 degrees C, start to increase the set temperature of the first water main unit. If the temperature is raised to 10 degrees C, the comfort level of the corresponding air conditioning facility can still be maintained for 15 minutes. At the edge of the lower limit of the set value, the second ice water host is turned off, or when the usage amount per unit time exceeds the budget, it is also turned off, and the set temperature of the first ice water host is adjusted back to 7 degrees C. If the client has three chilled water hosts connected in parallel, the control logic can be deduced by analogy. It should be noted that the above is only an embodiment of the present invention, and in other embodiments, it can also be controlled in other ways.

Referring to Fig. 2, it shows the flow chart of power consumption control in the present invention. Among them, steps 201-206 are the user setting process, the main purpose of which is to allow the user to set the power consumption, the power consumption control group, and the comfort level and priority setting. First enter into the setting process in step 201 . In step 202, the user is provided with basic data settings, such as the setting of a unified number, so that maintenance can be performed according to this number when subsequent searches are performed. In step 203, the user is provided with the setting of electricity consumption, that is, the user sets a budget for electricity consumption. Step 204 provides the user with the setting of the electricity control group. Since there are many units in a building, the user can group several units with the same nature into one group for joint management, so as to avoid the trouble of repeated settings. Step 205 provides the user with comfort and priority settings. After setting, enter the dynamic power consumption control system 300 of the present invention to control power consumption.

Wherein in the step 301 of setting the management function, the present invention will perform the simulation in the step 302 according to the setting result carried out by the user, and generate a simulation result chart, which will show the amount of electricity used by the air conditioner (step 3021) And possible causes of electricity waste (step 3022). According to the simulation result, the user can refer to and choose whether to go back to the setting step 201 for resetting.

In step 303 , the power consumption control group set by the user in step 204 is loaded into the dynamic power consumption management and control system 300 . In step 304 , the comfort level and priority set by the user in step 205 are loaded into the dynamic power management and control system 300 . In step 306 , the basic data set by the user in step 202 is loaded into the dynamic power consumption management and control system 300 . And in step 307 , the power consumption set by the user in step 203 is loaded into the dynamic power consumption management and control system 300 .

After the loading is completed, go to step 305 to manage the power consumption according to loading various data in the dynamic power consumption management and control system 300 and collaborating with the aforementioned seven management modules. It includes seven management steps, namely dynamic temperature management step 3051, operation schedule management step group 3053, idle space management step 3057, external air introduction management step 3052, heat source monitoring management step 3054, real-time leakage management step 3055 and system efficiency Manage Step 3056. The operation schedule management step group 3053 also includes an equipment schedule setting step 30531, which is used to arrange the sequence of starting up the equipment. Dynamic energy usage function scheduling setting step 30532, which is used to arrange the sequence of equipment power consumption up and down. Comfort and priority scheduling setting 30533, used to schedule the priority of comfort.

The following will use an embodiment to illustrate the application of the power consumption management and control process of the present invention to an air conditioning system. First, in step 201, a user enters the basic data on the system (step 202), the monthly air-conditioning target electricity consumption amount (step 203), facility group settings (step 204) and the comfort of each area. Degree and priority (step 205), when the setting is completed, the system loads the set value into the power consumption management and control system, and sets the monthly air conditioner power consumption target according to the set value and the corresponding power consumption management strategy.

In one embodiment, the operation scheduling management module of the present invention will use the off-peak electricity price to remove heat stored in the building between 7:00 am and 7:30 am. As for the setting of the chilled water host, the system efficiency management module of the present invention will automatically adjust the set temperature of the chilled water host, unless it is a particularly hot day, when the outlet temperature of a chilled water host cannot be set at a lower level to meet the comfort level , the system will start the second host again.

As for the air conditioner settings in the office, the dynamic temperature management module of the present invention will perform dynamic adjustments. Once the system calculates that the accumulated electricity consumption exceeds the pre-set value, it will be based on the priority value setting. The set temperature of rooms and offices will be gradually increased in sequence until the accumulated air-conditioning power consumption of the building returns below the set value.

In spring, autumn and winter, the external air introduction management module of the present invention can be used to introduce cool external air into the building, and the load of the air conditioner is greatly reduced; in summer, unless the carbon dioxide concentration exceeds the upper limit, it will not start External air system, when the concentration of carbon dioxide drops, it will immediately shut off the external air, so as to prevent the high temperature external air from entering and increasing the burden on the air conditioner. As for door and window management, the real-time leakage management module of the present invention will issue a warning of air-conditioning leakage, and even list the wasted energy, so as to strengthen management and avoid many unnecessary wastes.

In addition, the heat source monitoring and management module of the present invention will notify the user when to open or close the curtains, so as to reduce the load of the office air conditioner. When the user temporarily leaves the seat due to a meeting, the idle space management module of the present invention, after the user leaves the seat, will change the air conditioner to the air supply mode during the working hours, and turn off the office air conditioner during the off-duty hours.

In addition, the present invention can also use the predicted information as the basis for the power consumption control strategy. For example, in combination with the weather forecast of the Meteorological Bureau for the next week, the power control management system can use this to predict the future increase and decrease trend of power consumption and automatically readjust. target power consumption. For example, if the weather turns cold in the coming week, there should be room to reduce the power consumption of the air conditioner. The power control system can lower the target power consumption setting value for the next week according to the current power consumption situation to help users set the best The electricity consumption target and the budget saved during this period can also be used as a reserve fund for higher air-conditioning costs in the future when the weather turns hot.

In another embodiment, the schedule operation management can also be combined with the calendar information. For example, taking the Microsoft Outlook calendar as an example, the schedule registered by the user in the calendar can be used as a reference for the operation schedule management setting of the power control system. If the user registers the calendar of the meeting room from 9:00 am to 12:00 noon, the meeting room will automatically change to "Enable Idle Space Management" during this time period. If someone enters the meeting, it will be opened. If no one enters the meeting during this period, Air-conditioning and lighting facilities will not be enabled; at the same time, the temperature setting of the air-conditioning in the meeting room during this period can be set according to the comfort level that the registrants prefer, making the user interface smarter and more intimate.

In addition, in the implementation of comfort level setting, the power control system can provide a user operation interface, and through the interface, authorized individual users can feedback their feelings about the comfort level of the area, such as "hope warmer" or "hope cool When the user gives feedback, the system automatically records the environmental temperature and humidity information at that time, and establishes a comparison table.
