Description

  The present invention relates to an air-conditioning energy saving control device that reduces the total daily power consumption of an air conditioner.

  In general, a power charge is composed of a basic charge and a metered charge, and the basic charge is related to the maximum power consumption (demand power consumption). Since the basic charge occupies a large proportion of the electricity charge, it is important to lower the basic charge in order to reduce the electricity charge. In other words, reducing demand power at maximum load has been considered important for building energy management.

Therefore, the conventional air conditioning energy-saving control device controls the air conditioner so that the power consumption does not reach the demand target power value at the maximum load of air conditioning (see, for example, Patent Document 1). In addition, an energy-saving air-conditioning control system that reduces power consumption by efficiently reducing the power load of the outdoor unit while ensuring a work environment (preventing degradation of comfort) to reduce demand power at maximum load Is also known (see, for example, Patent Document 2).

  On the other hand, among many devices that aim to reduce demand power, air-conditioning energy-saving control devices that aim to obtain energy-saving effects without sacrificing comfort are also provided (for example, with the goal of reducing actual power consumption) (for example, (See Patent Document 3). In this device, by providing means for registering the upper and lower limits for the standard set temperature in the operation schedule of the air conditioner, and means for predicting the power consumption when operating with the set schedule, An optimal driving schedule is created.

Embodiment 1 FIG.
FIG. 1 shows an internal configuration of an air-conditioning energy-saving control device according to Embodiment 1 of the present invention and an outline of the surrounding air-conditioning system.
In the figure, an air-conditioning energy saving control device 1 according to the first embodiment includes a communication unit 2 that receives external information 101 and connection information 9a and operation information (operation state 9b, operation schedule 9e) of a plurality of indoor units 103a and 103b. , External information 101 received by the communication unit 2, the data storage unit 7 represented by a RAM or the like for storing connection information and operation information of the indoor units 103 a and 103 b, and the daily total reduction power target value for the external user From the input unit 5 typified by a keyboard for setting input from a display unit, the display unit 6 typified by a liquid crystal screen, etc., the control unit 3 and the calculation unit 4 embodied by a microcomputer or the like It is configured.

The communication unit 2 of the air-conditioning energy saving control apparatus 1 includes an air-conditioning system including one outdoor unit 102 and two indoor units 103a and 103b connected in parallel to the outdoor unit 102, and consumption of the air-conditioning system. A watt-hour meter 105 that detects the amount of electric power and a terminal of external information 101 necessary for predicting the power consumption of the day such as weather, maximum temperature, minimum temperature, and day of the week are connected to be communicable. The indoor units 103a and 103b are provided with temperature sensors 104a and 104b that detect the suction temperature of the room in which the indoor units are installed.

  Each function of the arithmetic unit 4 and the control unit 3 described above is implemented by, for example, a microcomputer CPU as shown in FIG. Then, the calculation unit 4 includes a power consumption prediction unit 121 for each time zone, a power reduction value calculation unit 122 for each time zone, a priority setting unit 123, a power reduction value calculation unit 124 for each air conditioner, Each function of the possible time zone extraction unit 125 and the unit time zone power reduction target value calculation unit 126 is provided. Each function of the calculation unit 4 and the control unit 3 is preset in the microcomputer CPU as a software program.

Next, the operation will be described. First, FIG. 3 shows a processing procedure for obtaining the external information 101 and predicting the power consumption of the day.
The external information 101 includes information on the current day's weather, maximum temperature, minimum temperature, weekdays / Saturdays, Sundays, and holidays, and is obtained from public weather forecast data and received by the communication unit 2 (step 201). The control unit 3 searches the past power consumption 8a held in the power data storage unit 8 of the data storage unit 7 for a date that matches the external information 101 (step 202). If there is a day that matches all the conditions (weather, maximum temperature, minimum temperature, weekdays / Saturdays, Sundays, and holidays), read the power consumption 8b attached to the most recent day within the corresponding day, The daily power consumption bar graph 106 as shown in FIG. 4 is displayed on the display unit 6 on the display unit 6 (steps 203 and 205). However, even if one-day power consumption data obtained by reducing power in the past is acquired, it is difficult to further reduce power from the data. Therefore, for the power reduction data with reduced power, the power consumption of the day that is the source of the reduction is output (steps 228, 229, and 205). If there is no day on which all the conditions match in step 202, the most recent daily power consumption 8b is read out on the same day of the week (weekdays / Saturdays, Sundays, and holidays) as the current day, and the graph of FIG. It is displayed on the display unit 6 (steps 204, 226, 205). Also in this case, if the data is power reduction data, the power consumption of the power reduction source is output (steps 230, 231 and 205).

If there is no matching day in step 204, the power consumption of the most recent day is read on the same day of the week as the current day, and the graph of FIG. 4 is displayed on the display unit 6 (steps 224, 227, 205). In this case as well, if the data is power reduction data, the power consumption of the power reduction source is output (steps 232, 233, and 205). When past data is insufficient and there is no matching data in step 224, the power consumption of the previous day is read and the graph of FIG. 4 is displayed on the display unit 6 (steps 225 and 205). In this case as well, if the power reduction data has been reduced in power, the power consumption of the power reduction source is output (steps 234, 235, 205). In addition, when acquiring information such as the weather of the day, in order to output the power consumption of the day, the timing of acquiring the information of the weather is the beginning of the day such as midnight. That is, the hourly power consumption prediction unit 121 of the calculation unit 4 compares the external information of the day received by the communication unit 2 with the past external information stored in the data storage unit 7 and the past external information. The power consumption value of each unit time zone on the current day is predicted based on the power consumption 8a of a plurality of unit time zones constituting one day stored in the power data storage unit 8 of the data storage unit 7 It is.

  In the daily power consumption bar graph 106 shown in FIG. 4, the horizontal axis represents 0 to 24:00, and the vertical axis represents the power consumption for one hour (unit time zone). It is estimated that the past one-day power consumption bar graph matches the one-day power consumption of the current day, and processing is performed from this estimated value to reduce the total daily power consumption value input by the user.

A processing procedure for allocating the daily total power reduction target input from the outside to the input unit 5 by the user to each unit time zone will be described with reference to the flowchart of FIG.
The daily total power reduction target value is input from the input unit 5 by the user. As an input method, “several percent reduction” or “several kWh reduction” may be input (step 206). In the former case, a calculation processing step (total power amount per day ×%) for the power amount in the calculation unit 4 is added (step 207). During 1 day, as shown in 1 to 6 o'clock in FIG. 4, it is not possible to reduce power consumption in the time zone where only the standby power 8c of the air conditioner is consumed, so it is necessary to exclude it from the power reduction target time zone in advance. Yes (steps 208 and 209). The standby power 8c is measured in advance by the watt-hour meter 105, and the sum of the number of managed units is held in the power data storage unit 8. The unit time zone in which standby power + standby power × 10% or less of power consumption is excluded from the power reduction target time. That is, the power saving possible time zone extraction unit 125 of the calculation unit 4 extracts and sets a unit time zone in which power saving is possible other than the time zone in which the standby power 8c is consumed.
The power consumption reduction amount in each unit time zone is calculated in proportion to the power consumption per hour because the power consumption is easier to reduce in the unit time zone with higher power consumption (step 210).
(Example) Calculation of reduction power target at 11-12 o'clock ・ Reduction target per day: 100 kWh
・ Predicted power consumption on the day (total): 1210 kWh
・ Estimated power consumption at 11-12 o'clock on the day: 100 kW
100 kWh × (100 kW / 1210 kWh) = 8.3 kW
The above calculation is executed for each unit time zone, and the reduction target 8 d for each unit time zone is stored in the power data storage unit 8. That is, the power reduction value calculation unit 122 according to time zone of the calculation unit 4 is set and input from the input unit 5 for the power consumption of each unit time zone of the day predicted by the power consumption prediction unit 121 for each time zone. The daily total power reduction target value stored in the storage unit 7 is allocated, and the power reduction value for each unit time zone is calculated. Further, the unit time power reduction target value calculation 126 of the calculation unit 4 is performed by the input unit 5 according to the power consumption values of a plurality of unit time zones constituting the power saving available time zone extracted by the power saving available time zone extraction unit 125. The total daily power reduction target value from the outside that is set and input is assigned to each unit time zone, and the power reduction target value for each unit time zone is calculated. At this time, the display unit 3 may have a function of displaying the daily power consumption and the target reduced power bar graph 107 as shown in FIG. On the other hand, the input unit 5 may be configured to be able to set and input a power saving time zone from the user.

After the reduction target 8d for each time slot is calculated, the reduction target 8e for each air conditioner is calculated for each unit time slot as shown in FIG.
Details of the flowchart shown in FIG. 7 will be described below.
The energy saving priority 9c of each air conditioner (for example, indoor units 103a and 103b) is set and input by the user from the input unit 5 (step 212). The energy saving priority that can be set is “0 to 4” as shown in the priority list 108 of FIG. 8, and the larger the value, the higher the energy saving priority. Also, the higher the energy saving priority is set, the more the indoor unit is located in the room where power is desired to be reduced. On the other hand, since the setting of an air conditioner in a room that should not be shut down, such as a computer room, must not be changed, the energy saving priority is set to “0” and excluded from the power consumption reduction target. The set energy saving priority 9c is stored in the air conditioner data storage unit 9 (step 213). That is, the priority setting unit 123 of the calculation unit 4 sets the energy saving priority 9c related to power reduction in each of the plurality of indoor units 103a and 103b and stores them in the air conditioner data storage unit 9.

  The power consumption 8b of each indoor unit for the latest one hour from the present is acquired from the watt-hour meter 105. The acquired power is a value obtained by combining the power consumed by each indoor unit and the value obtained by apportioning the power for each corresponding indoor unit from the power consumed by the outdoor unit. The obtained value is acquired via the communication unit 2 and held in the data storage unit 8 as the latest power consumption 8b. (Step 214)

The energy saving priority 9c set and input from the outside by the user and the power consumption 8b for the latest one hour of each indoor unit are read from the data storage unit 7 and multiplied by the arithmetic unit 4 to reduce the power consumption of each indoor unit The ratio 9d is calculated. The power reduction ratio 9d calculated in this way is stored in the air conditioner data storage unit 9 (step 215).
(Energy saving priority) x (most recent power consumption) = (power reduction ratio)

Each unit time of each indoor unit is calculated from the reduction target 8d of each unit time zone calculated in step 211 of FIG. 5 and the power reduction ratio 9d of each indoor unit calculated in step 215 of FIG. The reduction target 8e per band (one hour) is calculated and stored in the power data storage unit 8 (step 216).
The calculation method of the reduction target 8e is as follows.
(Target reduction in each unit time zone) * (Power reduction ratio of each indoor unit) / (Sum of power reduction ratios of all indoor units)
That is, the power saving value calculation unit 124 for each air conditioner of the calculation unit 4 uses the energy saving priority set for each of the indoor units 103a and 103b and the latest power consumption of each indoor unit 103a and 103b input from the communication unit 2. Based on the calculated power reduction ratio 9d and the reduction target 8d for each unit time zone calculated by the time-based power reduction value calculation unit 122, the reduction target 8e for each unit time zone of each indoor unit 103a, 103b. Are calculated respectively.
Then, a reduction target display screen 109 for each of the indoor units 103a and 103b as shown in FIG. On the reduction target display screen 109, it is possible to display all the data calculated in the processing procedure (steps 212 to 216) in FIG.

  For each model of each indoor unit, the indoor unit power consumption data 10 a per hour is calculated from information on the set temperature, the suction temperature, and the outside air temperature, and is stored in the model data storage unit 10. Data representing the indoor unit power consumption per hour is configured as a list shown in FIG. For example, the two indoor unit power consumption lists 110 (FIG. 10A) and 111 (FIG. 10B) shown in FIG. 10 store data of all models in advance at the stage where the air-conditioning energy-saving control device 1 is manufactured. It may be held. However, when the amount of data is too large, or when a new air conditioner model is developed, the power consumption 10a of the indoor unit of the data storage unit 10 can be updated from the external information 101 through the communication unit 2. The power consumption 10a of the indoor units 103a and 103b includes power that is apportioned to the power consumption 10b of the outdoor unit 102.

  When considering the power consumption reduction of the indoor units 103a and 103b, the set temperature is first changed. When the power reduction cannot be compensated only by changing the set temperature, the operation of the compressor of the outdoor unit 102 is stopped, and the operation of the indoor units 103a and 103b is changed to the thermo OFF mode.

  In order to achieve the reduction target per hour (unit time zone) of each indoor unit calculated above, the power consumption list 110 per hour for each model described in FIG. 10, the power consumption of the outdoor unit The list 111 is used, and the energy-saving operation is controlled according to the processing procedure of FIG. In addition, although the processing procedure of FIG. 11 is individually executed in each indoor unit, the case of the indoor unit 103a will be described below for easy understanding. In this embodiment, the power reduction target of the indoor unit 103a is 3 kW.

  Information on the current suction temperature and outside air temperature is acquired from the temperature sensor 104a and the outside air temperature sensor (not shown) of the indoor unit 103a (step 217). The set temperature is set and input by the user from the input unit 5 of the air-conditioning energy-saving control device 1, is managed as the operation schedule 9e in the air conditioner data storage unit 9, and is read out (step 218).

From the power consumption 10a, the power consumption at the current suction temperature, outside air temperature, and set temperature of the indoor unit 103a is obtained from the table of FIG. 10 (step 219).
(Example) In the indoor unit 103a, when the outside air temperature is 9 ° C, the suction temperature is 16 ° C, and the set temperature is 23 ° C,
[Power consumption = 15 kW]
In the power consumption list 110, the maximum power consumption is retrieved from the same outside air temperature and suction temperature data that is smaller than the current power consumption (15 kW) minus the reduction target (3 kW). Then, the set temperature is changed from the current value to the set temperature corresponding to the corresponding power consumption (steps 220 and 221).
(Example) 15kW-3kW = 12kW
(Outside air temperature 9 ° C and suction temperature 16 ° C → 12kW → set temperature 20 ° C)
Here, the set temperature of the indoor unit 103a is changed from 23 ° C. to 20 ° C.

As described above, when the corresponding set temperature exists in the power consumption list in step 221, the set temperature is changed to the corresponding temperature (step 222). In step 221, if the corresponding set temperature does not exist, energy saving is insufficient only by changing the set temperature with respect to the energy saving target value. 223). In other words, if the target power reduction cannot be achieved by changing the set temperature, the power consumption corresponding to the same outside air temperature and suction temperature as the current value is smaller than the current power consumption minus the target power reduction. When not in the list, the indoor unit is set to the thermo OFF operation. That is, the air conditioning unit-specific power reduction value calculation unit 124 of the calculation unit 4 sets each unit time of each indoor unit based on the energy saving priority and current power consumption of each indoor unit set and input by the input unit 5 from the user. The power reduction target value for the belt is calculated. And the control part 3 carries out operation control of each indoor unit 103a, 103b based on the power reduction target value of each unit time slot | zone of each indoor unit 103a, 103b calculated by the power reduction value calculation part 124 classified by air conditioner. It is.

  As described above, the daily total power reduction target is allocated to each unit time zone, and the power reduction target value is further allocated to each indoor unit within each unit time zone. A power consumption data list per hour for the indoor units 103a and 103b and the outdoor unit 102 is stored in advance, and power consumption corresponding to the current set temperature is obtained. And it changes to the preset temperature which can reduce the calculated | required target electric power part. On the other hand, when the power reduction is insufficient only by changing the set temperature, the thermo-OFF mode is changed. By executing these controls every hour, a reduction in the total power consumption of the air conditioner as a day can be achieved. However, when demand peak cut control is necessary for demand management, priority is given to demand peak cut control.

In the above embodiment, as shown in the flowchart of FIG. 5, the daily total reduction power target value is distributed to the target unit time zone. In such a case, a reduction target for each unit time zone may be set from the input unit 5 for a target time zone during which the user performs power reduction. By processing in this way, a flexible energy-saving operation can be performed according to the usage situation.

Embodiment 2. FIG.
Further, in the flowchart of FIG. 7, when setting and inputting the energy saving priority to each indoor unit from the input unit 5, instead of allowing the user to set and input the energy saving priority, as shown in FIG. The present invention is also applicable to an air conditioning system in which human sensors 114a and 114b that detect population density of people in a room where 103b is installed are connected to the indoor units 103a and 103b. The priority setting unit 123 of the calculation unit 4 calculates and sets the energy saving priority (= 0 to 4) based on the population density data from the human sensors 114a and 114b. For example, a higher energy saving priority may be set for a room with fewer people. The setting is performed using the list 115 shown in FIG. 13 according to the population density. In addition, since the information collection from the human sensors 114a and 114b is performed every hour, the latest energy saving priority can be obtained for each unit time zone, and the comfort of the air conditioner user (occupants) can be obtained. There is no loss.

  As described above, the energy saving priority 9c is automatically set using the human sensors 114a and 114b, and the hourly air conditioner subject to consideration for the air conditioner user (resident) is updated by updating the hourly. Can be realized.
