Detailed description of the invention
[inventive principle]
When calculating the effect for the Energy Saving Control of the equipment becoming object, in order to calculate this effect, consider that setting waits effect computing interval to a certain degree in such as 1 year, by the method that the energy input of a year implementing Energy Saving Control and the energy input of the whole of last year of not implementing Energy Saving Control compare.But because annual temperature on average is different, and there is warm winter or heat etc., so can easily imagine, be difficult to be regarded as both sides these effect computing intervals was all identical external condition in 1 year.Again, even if the effect computing interval is being set as one month, will the energy input of this month of Energy Saving Control implemented, and when the energy input of last month not implementing Energy Saving Control compares, owing to there are the transition in season, be therefore difficult to all regard both sides as identical external condition.
On the other hand, also consider to use correction, be similar to, analog computation goes out the method for the energy-saving effect under identical external condition.But, build and do not introduce the such high-precision innovation representation of error or the huge labour of approximate expression needs itself as far as possible, and for complexity object be unpractical.Again, consider, such as, using actual achievement data creating innovation representation or the approximate expression in cold summer, when analog computation goes out the energy-saving effect in the summer of heat, will become large based on the error revised, be similar to.
Therefore known, for the computational methods of these energy-saving effects, the external condition in the effect computing interval of comparing is different, and this just becomes the reason producing error when energy-saving effect calculates.
At this, even if the time location that there is the effect computing interval is different, the situation that external condition when carrying out Energy Saving Control to equipment is also roughly equal.Such as, with before 30 on the same day minute and now, or the phase in the same week at least energy-saving effect time span that can manifest such as in the same time, multiple short interval will be by piecemeal divided in the effect computing interval, select certain interval in these intervals, the situation being regarded as identical external condition is a lot.
The present invention notices, the reason of the error produced during such calculating energy-saving effect is, the difference of the external condition in the effect computing interval relatively, and exist and select in the segmentation effect computing interval as multiple and words in interval that are that arrange just regard the situation of identical external condition as.According to this, to the external condition of next interval predict device successively, predicting the outcome judge that whether the application for next interval Energy Saving Control needs based on this, by comparing the energy input obtained in external condition is identical in these intervals interval, calculating energy-saving effect.
Next, with reference to accompanying drawing, an embodiment of the present invention is described.
[energy-saving effect calculator]
First, with reference to Fig. 1, the energy-saving effect calculator 10 involved by this embodiment is described.Fig. 1 is the block diagram of the structure of the energy-saving effect calculator illustrated involved by this embodiment.
Energy-saving effect calculator 10 is made up of the information processor such as server unit or PC as a whole, it has following functions: within the preassigned effect computing interval, based on the energy input that this equipment when the Energy Saving Control of the equipment 30 becoming object being set to invalidating consumes respectively, calculate the energy-saving effect based on this Energy Saving Control.
Apparatus control system 20 has: the function of the running of control appliance 30; According to the instruction from energy-saving effect calculator 10, the invalidating switched for the Energy Saving Control of equipment 30 namely apply with presence or absence of function; By illustrating apparatus control system 20 informed to the external condition variate-value of the external condition that the energy-saving effect of equipment 30 impacts or detect the energy input that equipment 30 consumes and the function notified to apparatus control system 20.
Equipment 30 is the equipment that the air-conditioning equipment etc. arranged in high building or factory becomes the object of Energy Saving Control.Below, for the equipment 30 be made up of heat source system, be described for the situation of the Energy Saving Control of apparatus control system 20 Application Example described in aforementioned patent literature 1 (VWT control).
In energy-saving effect calculator 10, as main function part, be provided with communication I/F portion 11, operation inputting part 12, picture display part 13, storage part 14 and arithmetic processing section 15.

Operation inputting part 12 is made up of input devices such as keyboard, mouse, touch pads, has the operation detecting operator and the function exported to arithmetic processing section 15.
Picture display part 13 is made up of picture display devices such as LCD, has the function of the various picture datas such as the actions menu exported from arithmetic processing section 15, setting screen, energy-saving effect display frame being carried out to picture display.
Storage part 14 is made up of the storage device such as hard disk, semiconductor memory, has the function stored the various process data used in the energy-saving effect computing in arithmetic processing section 15 or program 14P.
Program 14P is by being performed at arithmetic processing section 15 place thus realizing the program of the various handling parts for energy-saving effect computing, is read by from the external device (ED) or storage medium that are connected to communication I/F portion 11 and is stored in advance in storage part 14.
As the main process data be stored in storage part 14, there are determinating reference value 14A, interval censored data 14B and compare data 14C.
Determinating reference value 14A illustrates for the value judging the allowed band whether external condition is identical between different interval, before energy-saving effect calculates, such as, is operated by the operator of operation inputting part 12 and is preset.Fig. 2 is the setting example of determinating reference value.At this, use cooling water temperature [DEG C] and load heat [kWh] as external condition variable, the allowed band for being judged to be identical external condition is preset respectively to them.
External condition refers to, on be applicable to equipment 30 Energy Saving Control energy-saving effect give with impact external condition.Such as, when equipment 30 is heat source systems, if the cooling water temperature that heat resource equipment utilizes is low, then thermal source efficiency is high, if cooling water temperature is high, then thermal source efficiency is low.Again, need the difference of the size of the load heat of supply according to equipment 30, thermal source efficiency, energy input change.
Like this, when external condition is different, even if apply same Energy Saving Control, the energy input needed then is also different.Therefore, even if compare the energy input obtained under different external conditions, also energy-saving effect accurately cannot be calculated.
The present invention's setting determinating reference value 14A as shown in Figure 2, comparing mutually meeting the energy input obtained in the interval of this determinating reference value 14A, calculating energy-saving effect accurately thus.
Interval censored data 14B is for the control content implemented in each interval is carried out as resume the data that record.Fig. 3 is the configuration example of interval censored data.At this, for each for the interval ID between cog region, the invalidating of the Energy Saving Control in the Start Date in this interval and time, this interval (apply with or without), as the cooling water temperature of the external condition variate-value measured in this interval and load heat, and the energy input of the equipment 30 measured in this interval is by group suppression.
Relatively data 14C be for record from interval censored data mutually between the valid interval of difference in the scope of determinating reference value 14A of external condition variate-value and the data of the group between dead space.Fig. 4 is the configuration example comparing data.At this, for each between these valid intervals and dead space, record interval ID, cooling water temperature, load heat and energy input.
Arithmetic processing section 15 has CPU and peripheral circuit thereof, having the program 14P by performing storage part 14, realizing the function of the various handling parts used in the calculating of energy-saving effect.
As the main handling part realized by arithmetic processing section 15, be provided with Energy Saving Control switching part 15A, interval censored data recording unit 15B, external condition prediction section 15C, invalidating detection unit 15D, energy-saving effect calculating part 15E and adjustment part 15F.Energy Saving Control switching part 15A has following functions: by communication, I/F portion 11 indicates to apparatus control system 20, thus, by using the time span segmentation effect computing interval that at least energy-saving effect can manifest be multiple interval arranged as unit, the invalidating of the Energy Saving Control in switching device 30.
When heat source system, although also rely upon equipment scale, but change heat resource equipment send coolant-temperature gage set after, send coolant-temperature gage action the words of about 30 minutes after heat resource equipment follows change, energy-saving effect just there will be, therefore, in this embodiment, the time span in interval is set to 30 minutes.Again, in order to calculate energy-saving effect, for switching the invalidating for the Energy Saving Control of equipment 30, the effect computing interval is set to 2 weeks.
Interval censored data recording unit 15B has and obtains following data as the interval censored data 14B of control content the function be recorded in storage part that implement in this interval are shown for each interval from communication I/F portion 11 and apparatus control system 20: in this interval mensuration, as the cooling water temperature (interval average) of external condition variate-value of external condition and load heat (interval add up) are shown, the invalidating of the Energy Saving Control in this interval, and the energy input of equipment to measure in this interval, the words of such as air-conditioning equipment, for the energy input of heat resource equipment and circulating pump.
External condition prediction section 15C has interval new within the effect computing interval when starting, and predicts the function as the cooling water temperature (interval average) of external condition variate-value and load heat (interval add up) in this new interval in advance.
About the prediction of external condition variate-value, use general forecast model.Such as, when the external condition variate-value based on the past is predicted, self-regression model can be used, namely predict that cooling water temperature in 30 minutes from now on and load heat are as next interval external condition variate-value.
In addition, about forecast model, also self-regression model can be replaced, use the physical model also using other explanatory variables obtained from equipment 30, or use the learning by rote such as neutral net, support vector regression, can also by the application plan of weather forecast data or building for illustration of variable.Again, the distribution of prediction also can be represented with possibility model.
Invalidating detection unit 15D has following functions: the function confirming the existence of (or valid interval) between dead space from interval censored data 14B, between this dead space in (or valid interval), Energy Saving Control regards as invalid (or effective), and, between this dead space (or valid interval) external variate-value and by predicting that the difference of the external condition variate-value in new interval obtained is in the scope of determinating reference value 14A, between this dead space (or valid interval) to be counted as the interval condition new with this identical; And whether exist according to (or valid interval) between this dead space, the invalidating of the Energy Saving Control in the interval new by this is indicated to the function of Energy Saving Control switching part 15A.
Energy-saving effect calculating part 15E has following functions: from interval censored data 14B, select the valid interval of the difference of external condition variate-value each other in the scope of determinating reference value 14A and the group between dead space respectively, and be recorded in the function compared in data 14C; And by the difference of the valid interval of each group of total record in relatively data 14C and the energy input between dead space, calculate the function of the energy-saving effect (energy-saving effect amount and reduction rate) in the effect computing interval.
Adjustment part 15F has following functions: in interval censored data 14B, the ratio of the valid interval of difference in the scope of determinating reference value 14A of mutual external condition variate-value and the group between dead space or quantity are below threshold value, the function of the scope of expansion determinating reference value 14A; With in interval censored data 14B, the ratio of the valid interval of difference in the scope of determinating reference value 14A of mutual external condition variate-value and the group between dead space or quantity are below threshold value, shorten the function of interval time span.
[action of this embodiment]
Next, with reference to accompanying drawing, the various actions of the energy-saving effect calculator 10 involved by this embodiment are described.
Whether [energy-conservation needs determination processing]
First, with reference to Fig. 5, whether determination processing is described the energy-conservation needs performed when starting interval.Fig. 5 is the flow chart that energy-conservation needs whether determination processing is shown.
When the interval that external condition prediction section 15C is new within the effect computing interval starts, predict the external condition variate-value in this new interval in advance, be cooling water temperature and load heat (step 100) herein.
Next, invalidating detection unit 15D retrieve from interval censored data 14B Energy Saving Control is set to invalid, be counted as between the dead space identical with new interval condition (step 101) based on determinating reference value 14A.
At this, when finding between dead space (step 102: "Yes"), invalidating detection unit 15D indicates effective (having application) (step 103) of Energy Saving Control in new interval to Energy Saving Control switching part 15A.
On the other hand, when not finding between dead space (step 102: "No"), invalidating detection unit 15D indicates invalid (not applying) (step 104) of the Energy Saving Control in new interval to Energy Saving Control switching part 15A.
Like this, after the invalidating of the Energy Saving Control in new interval is determined, after indicating the switching of the invalidating of the Energy Saving Control relevant to new interval as required by Energy Saving Control switching part 15A, intervally to start.
Like this, after new interval starts, interval censored data recording unit 15B obtains cooling water temperature, load heat and energy input from communication I/F portion 11 and apparatus control system 20, be recorded in the interval censored data 14B of storage part 14 successively, until (step 105) is terminated in this interval, terminate a series of energy-conservation needs whether determination processing.
In addition, in a flow chart in figure 5, although retrieved in a step 101 between dead space, but on the contrary, also can indicating the stopping (step 104) of Energy Saving Control when retrieving valid interval and valid interval is found, indicating the beginning (step 103) of Energy Saving Control when not finding valid interval.
[comparing data recording and processing]
Next, with reference to Fig. 6, the comparison data recording and processing performed at the end of interval is described.Fig. 6 illustrates the flow chart comparing data recording and processing.
Energy-saving effect calculating part 15E is at the end of new interval, when this interval is the valid interval applying Energy Saving Control (step 110: "Yes"), between the dead space of the difference retrieving the external condition variate-value in external condition variate-value and this interval from interval censored data 14B in the scope of determinating reference value 14A (step 111).
At this, when finding between dead space (step 112: "Yes"), the group between this interval and dead space being recorded in and comparing (step 113) in data 14C, terminate a series ofly to compare data recording and processing.
Again, when not finding between dead space (step 112: "No"), not to comparing data 14C record, terminate a series ofly to compare data recording and processing.
On the other hand, when this interval be apply Energy Saving Control dead space between (step 110: "No"), from interval censored data 14B, retrieve the valid interval (step 114) of difference in the scope of determinating reference value 14A of the external condition variate-value in external condition variate-value and this interval.
At this, when finding valid interval (step 115: "Yes"), the group between this interval and dead space being recorded in and comparing (step 116) in data 14C, terminate a series ofly to compare data recording and processing.
Again, when not finding valid interval (step 115: "No"), not to comparing data 14C record, terminate a series ofly to compare data recording and processing.
Fig. 7 is the action case of the energy-saving effect calculator involved by this embodiment.
At this, show the example being provided with n (n is positive integer) individual interval S1 ~ Sn within the effect computing interval, from interval S1, arrive according to time sequencing in each interval.At this, in interval S1 ~ Sn, the interval of having drawn oblique hachure represents do not have applicating energy-saving to control, and blank interval represents and applies Energy Saving Control.
Therefore, in interval S1, S2, owing to not existing before this between dead space in the scope of determinating reference value 14A of the difference of predicted external condition variate-value always, therefore show these interval S1, S2 and be judged as between dead space.Again, in interval S3, because interval S1 is as existing between dead space in the scope of determinating reference value 14A of the difference of predicted external condition variate-value, therefore between viewing area, S3 is judged as valid interval.
Therefore, at the end of interval S3, external condition variate-value and actual measurement to dead space in the scope of determinating reference value 14A of the difference of external condition variate-value of interval S3 between again retrieved, interval S1 is selected again, result, these interval S1, S3 by as group P1 and selecting, and are recorded in and compare in data 14C.
Again, about interval S8, because interval S6 is as existing between dead space in the scope of determinating reference value 14A of the difference of external condition variate-value and predicted external condition variate-value, therefore interval S8 is judged as valid interval.But, at the end of interval S8, retrieval external condition variate-value and by between dead space in the scope of determinating reference value 14A of the difference of the external condition variate-value of interval S3 of surveying, interval S5 is selected, instead of interval S6, as a result, these interval S5, S8 by as group P2 and selecting, and are recorded to and compare in data 14C.
In addition, in invalidating detection unit 15D, energy-saving effect calculating part 15E, when group when between selection area, for as group by the interval that have selected, also can forbid being repeated to select as group with other interval.Thereby, it is possible to avoid reusing of the energy input measured between same zone.
Like this, be recorded in and compare each group of valid interval in data 14C and the energy input between dead space is added up by energy-saving effect calculating part 15E, energy-saving effect in the effect computing interval is calculated, and carries out picture display by energy-saving effect display frame at picture display part 13 to operator.
Fig. 8 is energy-saving effect display frame example (accumulation).At this, compare in data 14C, the aggregate-value of the aggregate-value of the energy input between each dead space and the energy input of each valid interval is calculated by energy-saving effect calculating part 15E, shows with column diagram.Again, the difference of these aggregate-values, according to based on the energy reduction amount of Energy Saving Control and reduction rate, is shown by column diagram.Thus, operator can confirm the energy-saving effect for the accumulation of all external conditions easily.
Fig. 9 is energy-saving effect display frame example (layering).At this, be provided with the input field of cooling water temperature scope as external condition and load thermal range, operator can specify desired level.Thus, compare in data 14C, the aggregate-value of energy input of the aggregate-value of the energy input between the dead space belonging to the level that operator specifies and the valid interval that belongs to this level is calculated by energy-saving effect calculating part 15E, shows with column diagram.Again, the difference of these aggregate-values, according to based on the energy reduction amount of Energy Saving Control and reduction rate, is shown by column diagram.Thus, operator can confirm the energy-saving effect for the external condition accumulation belonging to the level of specifying arbitrarily easily.
When the use energy effect involved by this embodiment is confirmed that device 10 is used in the evaluation of new Energy Saving Control, through such as 2 weeks of the effect computing interval, energy-saving effect is calculated, when the energy-saving effect of expecting is confirmed, be just transitioned into the row for the national games of Energy Saving Control.Now, in row for the national games, owing to fully obtaining the benefit of Energy Saving Control, preferably always make Energy Saving Control effective.In addition, also when confirming the energy-saving effect not obtaining expecting, the row for the national games of Energy Saving Control can be cancelled, carries out the adjustment of Energy Saving Control.
Again, such as in the way in effect computing interval or at the end of, in interval censored data 14B, the ratio of the valid interval of difference in the scope of determinating reference value 14A of mutual external condition variate-value and the group between dead space or quantity are below threshold value, adjustment part 15F also can expand the scope of the determinating reference value 14A of storage part 14.Or, also in interval censored data 14B, the ratio of the valid interval of difference in the scope of determinating reference value 14A of mutual external condition variate-value and the group between dead space or quantity are below threshold value, interval time span can be shortened.In addition, when the change of the change of determinating reference value 14A or the time span in interval is performed, the new effect computing interval is just set and calculates energy-saving effect.
Thus, when being counted as the identical interval of external condition and being less, the scope of determinating reference value 14A is expanded, or the time span in interval is shortened.Therefore, it is possible to the group be counted as between the identical valid interval of external condition and dead space just increases, its result, can calculate energy-saving effect that is more accurate and tool reliability.
[effect of this embodiment]
Like this, according to this embodiment, by Energy Saving Control switching part 15A, to be that multiple interval arranged is as unit using the time span segmentation effect computing interval that at least energy-saving effect can manifest, the invalidating of the Energy Saving Control of switching device, by interval censored data recording unit 15B, to each interval, by illustrating of measuring in this interval to the external condition variate-value of the external condition affected with energy-saving effect, the invalidating of the Energy Saving Control in this interval, and the energy input of equipment to measure in this interval, as illustrating that the interval censored data 14B of the control content implemented in this interval is recorded in storage part 14, by energy-saving effect calculating part 15E, the valid interval of the difference of mutual external condition variate-value in the scope of determinating reference value and the group between dead space is selected respectively from interval censored data 14B, the difference of the energy input between respective valid interval and dead space is organized based on these, calculate the energy-saving effect in the effect computing interval.
Thus, for each interval in effect computing interval, the invalidating of Energy Saving Control is switched, and can be counted as the group energy input difference separately between identical valid interval and dead space, calculate the energy-saving effect in the effect computing interval based on external condition mutual in these intervals.
Therefore, do not need the correction of energy-saving effect or approximate, the impact of external condition is few, can calculate energy-saving effect more accurately.
Again, in this embodiment, also external condition prediction section 15C can be passed through, when interval new in the effect computing interval starts, predict the external condition variate-value in this new interval in advance, by invalidating detection unit 15D, the existence be set to by Energy Saving Control between invalid dead space is confirmed from interval censored data 14B, and, external variate-value between this dead space with by predicting that the difference of external condition variate-value in the new interval obtained is in the scope of determinating reference value, whether exist according between this dead space, the invalidating of the Energy Saving Control in the interval new by this is indicated to Energy Saving Control switching part 15A.
Thus, can be counted as according to external condition whether existing between the dead space identical with new interval, the invalidating of the Energy Saving Control in new interval is determined automatically, therefore can be counted as between identical valid interval and dead space by generation external condition in extreme efficiency ground, its result, calculating energy-saving effect more accurately becomes possibility.
Again, in this embodiment, also can pass through energy-saving effect calculating part 15E, add up to the difference that the valid interval in each group and the external condition variate-value between dead space belong to the group of the scope of specifying relevant, calculate the energy-saving effect be layered in the effect computing interval thus.
Thus, operator can confirm the energy-saving effect for the external condition accumulation belonging to the level of specifying arbitrarily easily.
Again, in this embodiment, also can form determinating reference value by the respective allowed band of each external condition variate-value individual settings.Thereby, it is possible to the homogeny of external condition between in more detail between setting district judges, its result, calculating energy-saving effect more accurately becomes possibility.
Again, in this embodiment, also can pass through adjustment part 15F, in interval censored data 14B, the ratio of the valid interval of difference in the scope of determinating reference value of mutual external condition variate-value and the group between dead space or quantity are below threshold value, the scope of expansion determinating reference value.Again, also in interval censored data 14B, the ratio of the valid interval of difference in the scope of determinating reference value of mutual external condition variate-value and the group between dead space or quantity are below threshold value, interval time span can be shortened.
Thus, when being counted as the identical interval of external condition and being less, the scope of determinating reference value 14A is expanded, or the time span in interval is shortened.Therefore, it is possible to the group be counted as between the identical valid interval of external condition and dead space just increases, its result, can calculate energy-saving effect that is more accurate and tool reliability.
Again, as new problem solved by the invention, there are the needs of following such application supplier: when this energy-saving control method is imported into as other software application utilized by apparatus control system 20, such as within the free trial period, confirm energy-saving effect to user, if obtain effect to a certain degree, just wish that user formally uses software application with compensation.
In this case, not calculate based on the effect of the viewpoint of annual or the comprehensive energy consumption amount of month and so on, can be more relevant to the interests of application supplier to confirm the independent effect of this application as far as possible in short time.
According to the present invention, owing to can be matched with other Energy Saving Control different because user is different, calculate the actual achievement of energy-saving effect more in short time, therefore user can confirm effect in short time.Therefore, just can the direction of software application be formally used to guide with compensation to continuation user.
