Embodiment
Accompanying drawing below with reference to example embodiment of the present invention shown in it describes the present invention.
Fig. 1 illustrates the block diagram that comprises the electric system 190 of demand controller 100 according to an embodiment of the invention.With reference to figure 1, electric system 190 comprises a plurality of air governors 141, a plurality of ventilation equipment 142 and a plurality of light fixture 143.Each air governor 141 can comprise a plurality of indoor unit (not shown) that are arranged on the interior space and a plurality of outdoor unit (not shown) that are arranged on the exterior space, but the present invention is not limited to this.
The a plurality of demand control programs of demand database 130 storages, these demand control programs are used to according to each national electricity consumption expenses standard electric system 190 execution demands be controlled.Demand controller 110 can be present in one of demand control program in the demand database 130 by use and come to the control of first to the 3rd local controller, 161 to 163 execution demands and thus finally to air governor 141, ventilation equipment 142 and the control of light fixture 143 execution demands.
Estimate that electric energy detection unit 170 is connected to watt-hour meter 171, watt-hour meter 171 is connected to a plurality of electric equipment.Estimate that electric energy detection unit 170 receives the electric energy measurement data that obtain by measurement electric energy in the time of scheduled volume from watt-hour meter 171, and based on the electric energy measurement data estimation electric energy that is received.Afterwards, estimate that whether electric energy detection unit 170 definite estimation electric energy are above electric energy being set and will determining that the result sends to demand controller 110.Demand controller 110 is connected to outdoor unit and the indoor unit of estimating electric energy detection unit 170 and being connected to each air governor 141.Like this, if estimate electric energy above electric energy is set, the then outdoor unit of demand controller 110 each air governor 141 of control and the running of indoor unit.
Different countries can adopt different demand control programs.For example, in Japan, one month power consumption served as to measure at interval with 30 minutes, and the maximal value of measured electric weight is confirmed as corresponding month maximum power consumption.Halfhour maximum power consumption can be confirmed as the contract electric energy in this year in arbitrary day of last year.Correspondingly, the electricity charge in this year can be multiply by unit price by the contract electric energy with this year and calculated.If the used electric energy of user surpasses the contract electric energy, then may cause extra cost.Therefore, if halfhour maximum power consumption was big in arbitrary day of last year, then the power consumption in this year may unnecessarily increase.In Japan, for head it off, halfhour total electricity consumption is restricted to and is lower than the predetermined power level.For this reason, can make and in all sorts of ways.Demand controller 100 can be by stopping some air governors 141 running or when some indoor unit 141b of each air governor 141 carry out cooling down operations the indoor temperature that is provided with of rising respective chambers unit 141b reduce power consumption.Japanese Patent Laid Open Publication communique 2000-131688 and 2000-182920 disclose the detailed description of above-mentioned Japanese demand control method.Because the electric charge calculating method that Korea S adopts is closely similar with the electric charge calculating method that Japan adopts, so Korea S also can adopt above-mentioned Japanese demand control method.
In the country of the annual total electricity consumption of restriction, demand controller 100 can use and relate to the demand control program that annual power consumption is limited in specific power level.On the other hand, in the country that the tariffs on electricity of peak period is provided with highly than the tariffs on electricity of non-peak period, demand controller 100 can use and relate to the demand control program that only in the peak period annual power consumption is limited in specific power level.
Fig. 2 illustrates the block diagram of the control module of demand shown in Fig. 1 110.With reference to figure 2, demand control module 110 comprises: distribute the priority of priority that device 111 is set to each air governor 141; The demand controlled stage that the demand controlled stage is set in view of energy-conservation necessary degree is provided with device 112; And the running controller 113 of the running of controlling air governor 141 according to the priority and the demand controlled stage of air governor 141.
Surpass predetermined power if estimate electric energy, the running rate that the controller 113 that then turns round can reduce air governor 141 successively by the backward with the priority of air governor 141 comes the control of execution demand.
Priority is provided with device 111 can distribute priority to each air governor 141 by user's setting or default setting.Owing to probably under difference running environment, drive the indoor unit 141b of each air governor 141,, priority can distribute priority to each air governor 141 in view of the characteristic of the running environment of the indoor unit of each air governor 141 so being provided with device 111.
Fig. 3 illustrates the block diagram of air governor shown in Fig. 1 141.With reference to figure 3, air governor 141 comprises at least one outdoor unit 141a of a plurality of indoor unit 141b and control indoor unit 141b.Each indoor unit 141b comprises the indoor temperature detecting device 141c that measures indoor temperature.Priority is provided with device 111 and can measures to air governor 141 distribution priority based on the indoor temperature that indoor temperature detecting device 141c provides.More particularly, because being provided with device 111, the load of the difference of the measured indoor temperature that the expectation indoor temperature that the user is provided with and each indoor temperature detecting device 141c provide reflection air governor 141, priority can distribute priority to air governor 141 in view of the difference of expecting the measured indoor temperature that indoor temperature and each indoor temperature detecting device 141c provide.
Fig. 4 illustrates the process flow diagram of demand control method according to an embodiment of the invention.With reference to figure 4, estimate that electric energy detection unit 170 receives the electric energy measurement data that obtain by the electric energy of measuring each air governor 141 in the time of scheduled volume from watt-hour meter 171, and based on the electric energy measurement data estimation electric energy (S10) that is received.Afterwards, estimate that whether electric energy detection unit 170 definite estimation electric energy are above electric energy (S20) is set.If determined the estimation electric energy above electric energy is set, then demand database 130 calculates the poor of each measured indoor temperature that the indoor temperature detecting device 141c of expectation indoor temperature that users are provided with and each air governor 141 provides, and storage computation result (S30) therein.The difference of expectation indoor temperature and each measured indoor temperature can reflect the load of the indoor unit 141b of each air governor 141.Like this, priority is provided with device 112 can distribute priority to each indoor unit 141b of each air governor 141, and making provides the indoor unit 141b that differs not too big measured indoor temperature with the expectation indoor temperature can be set to low priority (S40).For example, if each measured indoor temperature that indoor unit 141b provides differs quite big with the expectation indoor temperature, can determine that then the load of indoor unit 141b is big.The high indoor unit 141b that loads can be set to high priority, is subjected to demand control so that be later than the low indoor unit 141b of load.More particularly, it has been generally acknowledged that the room that the high indoor unit 141b of load is installed is more uncomfortable.Like this, if turn-off the high indoor unit 141b of load as the part of demand control or reduce the running rate of the high indoor unit 141b of load, the room that the high indoor unit 141b of load then is installed may become more uncomfortable, and therefore user satisfaction may reduce.On the other hand, owing to it has been generally acknowledged that the room that the low indoor unit 141b of load is installed is comfortable, even so turn-off the low indoor unit 141b of load as the part of demand control or reduce the running rate of the low indoor unit 141b of load, user satisfaction also may not reduce a lot.Therefore, after the priority of the indoor unit 141b that has determined each air governor 141, running controller 113 reduces the running rate (S50) of the indoor unit 141b of each air governor 141 successively with the backward of the priority of air governor 141.
Priority is provided with the priority that device 111 can be determined the indoor unit 141b of each air governor 141 based on the rate of temperature change in the room of the indoor unit 141b that is separately installed with each air governor 141, because the rate of temperature change of the indoor unit 141b of each air governor 141 also reflects the load of the indoor unit 141b of each air governor 141.More particularly, demand database 130 is stored the rate of temperature change measurement data that the indoor temperature detecting device 141c of each air governor 141 provides therein.Priority is provided with device 111 can be set to low priority with reference to being present in the indoor unit 141b that rate of temperature change measurement data in the demand database 130 has low rate of temperature change.When indoor unit 141b had high rate of temperature change, the load of determining indoor unit 141b was high, and distributed high priority to indoor unit 141b, and making can be in the demand of slow demand control stage control indoor unit 141b.
With reference to figure 2, the demand controlled stage is provided with device 112 can be provided with the demand controlled stage based on energy-conservation necessary degree.Demand control is the process that reduces the power consumption of air governor 141 by the running rate of control air governor 141, and demand controlled stage indication demand is controlled the degree that will carry out and reflected energy-conservation necessary degree.For example, in summer, the power consumption of air governor 141 enlarges markedly and therefore very possible surpassing estimated power consumption, and like this, energy-conservation necessary degree improves.Therefore, can make and to carry out energy-conservation to air governor 141 rapidly for high demand controlled stage is set summer.
Can respond the user and to the control signal of demand controller 100 inputs the demand controlled stage is set by input block 120.Yet, owing to might under varying environment, drive the indoor unit 141b of each air governor 141, so can determine the demand controlled stage automatically according to the characteristic of the running environment of the indoor unit 141b of each air governor 141.
Can apply the demand controlled stage uniformly to air governor 141.The indoor temperature measurement that the demand controlled stage is provided with device 112 can be provided based on the indoor temperature detecting device 141c of each air governor 141 is provided with the demand controlled stage.That is to say, the demand controlled stage is provided with device 112 can determine the demand controlled stage according to the characteristic of the running environment of the indoor unit 141b of each air governor 141 (difference of each measured indoor temperature of providing of the indoor temperature detecting device 141c of the expectation indoor temperature that is provided with according to the user and each air governor 141 or be separately installed with the rate of temperature change in room of the indoor unit 141b of each air governor 141) in particular.
More particularly, demand database 130 can calculate the poor of each measured indoor temperature that the indoor temperature detecting device 141c of expectation indoor temperature that the user is provided with and each air governor 141 provides, and can be with the result of calculation addition.Then, the demand controlled stage is provided with device 112 and can the demand controlled stage be set according to the summation of the difference of expecting indoor temperature and each measured indoor temperature.Thereby the summation of the difference of expectation indoor temperature and each measured indoor temperature is big more, and it is high more that the demand controlled stage becomes.As mentioned above, if each measured indoor temperature that indoor unit 141b provides differs quite big with the expectation indoor temperature, determine that then the load of indoor unit 141b is high.Because very possible quite a large amount of power and the therefore final energy that consumes more than expection of consuming at short notice of the indoor unit 141b that load is high, so the demand controlled stage is provided with can be for the such load high indoor unit 141b rising demand controlled stage of device 112, make the control of execution demand rapidly.Can in demand database 130, store the related table between the summation of the difference that each measured indoor temperature that demand controlled stage and the indoor unit 141b of expectation indoor temperature and each air governor 141 provide is shown.Then, the demand controlled stage is provided with device 112 and can raises for all air governors 141 or reduce the demand controlled stage with reference to being present in contingency table in the demand database 130.On the other hand, if each measured indoor temperature that indoor unit 141b provides differs not too big with the expectation indoor temperature, determine that then the load of indoor unit 141b is low.Because the quite a large amount of power of the unlikely consumption at short notice of the indoor unit 141b that load is low, can reduce the demand controlled stage by low indoor unit 141b for such load so the demand controlled stage is provided with device 112, make and not damage the demand that respective chambers unit 141b is controlled on user satisfaction ground.
Alternatively, demand database 130 can calculate the rate of temperature change in the room of the indoor unit 141b that is separately installed with each air governor 141, and can be averaged result of calculation.Then, the demand controlled stage is provided with device 112 and can the demand controlled stage be set according to the mean value of the rate of temperature change in the room of the indoor unit 141b that is separately installed with each air governor 141.Thereby the mean value of rate of temperature change in room of indoor unit 141b that is separately installed with each air governor 141 is big more, and it is high more that the demand controlled stage becomes.Because the indoor unit 141b in the high room of rate of temperature change is confirmed as having high load capacity, so the demand controlled stage is provided with device 112 high demand controlled stage can be set for such indoor unit 141b, the execution demand rapidly that makes is controlled.Can in demand database 130, store the related table between the mean value that demand controlled stage and the rate of temperature change in the room of the indoor unit 141b that is separately installed with each air governor 141 are shown.Then, the demand controlled stage is provided with device 112 and can raises for all air governors 141 or reduce the demand controlled stage with reference to being present in contingency table in the demand database 130.
Can apply the demand controlled stage uniformly to all air governors 141, perhaps can the demand controlled stage differently be set for each indoor unit 141b of each air governor 141.Fig. 5 illustrates to be used to explain how to be the sequential chart that each indoor unit differently is provided with the demand controlled stage.With reference to figure 5, the time period of shadow region indication execution demand control, the time period of non-hatched area indication cancellation demand control.With reference to figure 5, can to each indoor unit among the D differently be set the duration that demand is controlled for indoor unit A, make and can control to differently execution demand of D indoor unit A.
After the demand controlled stage is provided with device 112 and is provided with the demand controlled stage, the controlled stage execution demand control according to demand of running controller 113.To describe how according to demand controlled stage execution demand control below in detail.
Along with the rising of demand controlled stage, running controller 113 can increase the number of the indoor unit 141b that need be subjected to demand control gradually.That is to say, when high demand controlled stage being set, can making the indoor unit 141b of suitable big figure be subjected to demand control, thereby realize energy-conservation rapidly owing to energy-conservation necessary degree is high.Alternatively, along with the rising of demand controlled stage, running controller 113 can increase the reduced rate of running rate of each indoor unit 141b of each air governor 141 gradually.In the process of demand control, can reduce the running rate of each indoor unit 141b of each air governor 141.When owing to energy-conservation necessary degree is high high demand controlled stage being set, running controller 113 can increase the reduced rate of running rate of each indoor unit 141b of each air governor 141.For example, when the demand controlled stage was low, the reduced rate of the running rate of each indoor unit 141b that running controller 113 can each air governor 141 was set to 50%.On the other hand, when the demand controlled stage was high, the reduced rate of the running rate of each indoor unit 141b that running controller 113 can each air governor 141 was set to 70%.
Fig. 6 illustrates the process flow diagram of demand control method according to another embodiment of the invention.With reference to figure 6, estimate that electric energy detection unit 170 receives the electric energy measurement data that obtain by the electric energy of measuring each air governor 141 in the time of scheduled volume from watt-hour meter 171, and based on the electric energy measurement data estimation electric energy (S100) that is received.Afterwards, estimate that whether electric energy detection unit 170 definite estimation electric energy are above electric energy (S200) is set.If determined the estimation electric energy above electric energy is set, then demand database 130 calculates the poor of each measured indoor temperature that the indoor temperature detecting device 141c of expectation indoor temperature that users are provided with and each air governor 141 provides, and storage computation result (S300) therein.The difference of expectation indoor temperature and each measured indoor temperature can reflect the load of the indoor unit 141b of each air governor 141.Like this, priority is provided with device 112 can distribute priority to each indoor unit 141b of each air governor 141, and making provides the indoor unit 141b that differs not too big measured indoor temperature with the expectation indoor temperature can be set to low priority (S400).After the priority of the indoor unit 141b that has determined each air governor 141, the demand controlled stage is provided with device 112 can be provided with demand controlled stage (S500) for all air governors 141.Afterwards, running controller 113 can determine to be subjected to some indoor unit 141b (S600) of demand control based on the demand controlled stage.Afterwards, running controller 113 can reduce the running rate of respective chambers unit 141b successively with the backward of the priority that is determined the indoor unit 141b that need be subjected to demand control.
Each air governor 141 can comprise at least one the outdoor unit 141a with compressor (not shown).Demand control module 110 is the capacity of the compressor of the outdoor unit 141a of controlled stage change air governor 141 according to demand.More particularly, the demand controlled stage is provided with device 112 and for all air governors 141 the demand controlled stage is set according to the above-mentioned rule sets that is used to be provided with the demand controlled stage.Then, running controller 113 according to demand controlled stage device 112 set demand controlled stages be set come execution demand control.Each outdoor unit 141a of air governor 141 can comprise the inverter compressor that can compress with the corresponding a certain amount of cold-producing medium of required air regulating power.For the capacity of the inverter compressor of the outdoor unit 141a that changes air governor 141, running controller 113 can change the operating frequency of inverter compressor of the outdoor unit 141a of air governor 141.More particularly, because the variation of the rotations per minute (RPM) of inverter compressor, so might the rapid environment of setting up through suitable artificial atmosphere.In addition, owing to need not to open or close the cold-producing medium that compressor just can compress desired amount, so might reduce the noise that produces when opening or closing compressor.The amount of the inverter compressor institute refrigerant compressed of the RPM of the inverter compressor of the outdoor unit 141a of air governor 141, the outdoor unit 141a of air governor 141 and the air handling capacity of air governor 141 can be determined according to the operating frequency of the inverter compressor of the outdoor unit 141a of air governor 141.Therefore, according to demand the operating frequency of the inverter compressor of controlled stage, the outdoor unit 141a by changing air governor 141 change air governor 141 outdoor unit 141a inverter compressor capacity and change the operating condition of the indoor unit 141b of each air governor 141 thus.
The indication of demand controlled frequency is the frequent degree of the interior execution demand control of section at the fixed time.This predetermined amount of time can be one day, a week or January.After being provided with the demand controlled frequency, each air governor 141 is controlled to be at the fixed time the demand control that is not subjected in the section more than pre-determined number.
For the demand controlled frequency is set, the user can perhaps can control historical data with reference to the demand that is present in the demand database 130 by input block 120 input control signals.More particularly, can be construed to be the demand controlled frequency that each the indoor unit 141b for each air governor 141 is provided with to the demand controlled frequency that is provided with for each air governor 141.How, demand database 130 storage indications are historical to the demand control of each air governor 141 execution demands control.More particularly, the historical indication of demand control which air governor 141 be subjected to recently demand control and at the fixed time in the section to the frequent degree of each air governor 141 execution demands control.This predetermined amount of time can be set to one month.Then, demand database 130 can keep that each air governor 141 is subjected to the record of the number of times of demand control in last month, and creates demand controlled frequency table thus.Then, can for each air governor 141 the demand controlled frequency be set by reference requirement controlled frequency table, make and for the air governor 141 of the least number of times that is subjected to demand control in last month the highest demand controlled frequency to be set.
