Description

The present invention relates to a hot / cold feeling report information processing device and a method for processing hot / cold feeling report information from a resident of an evaluation target space.

Conventionally, in buildings such as buildings, the air-conditioning environment (living environment) of the building is used by using PMV (Predicted Mean Vote), which is an index of thermal environment, and PPD (Predicted Percentage Dissatisfied), which is the dissatisfaction rate calculated by using PMV (Predicted Mean Vote). ) Is evaluated, and the air conditioning is operated while the facility manager takes care not to sacrifice excessive comfort. Due to the growing needs for prevention of global warming and further energy saving (hereinafter abbreviated as energy saving), thorough extraction of energy saving room is required, and more accurate living environment evaluation is required.

PMV and PPD are indexes internationally standardized by ISO-7730, and SET * (Standard) defined in the standards of the American Society for Heating, Refrigerating and Air-Conditioning (ASHRAE) as an evaluation index for the thermal environment used in the same way. new Effective Temperature) and so on.

Japanese Unexamined Patent Publication No. 05-322258 Japanese Unexamined Patent Publication No. 2016-223704 Japanese Unexamined Patent Publication No. 2008-241153 Japanese Unexamined Patent Publication No. 2015-4480

In the air-conditioned environment of the building, the comfort and dissatisfaction are evaluated according to the actual condition of the resident's feelings by using the warm / cold feeling report (“hot / cold” report) from the resident, and the air-conditioned environment is managed. There is a hot / cold feeling reporting system used for air conditioning and control (see, for example, Patent Document 1). However, with this method, it is difficult to realize an evaluation that matches the actual situation unless a sufficient number of declarations are obtained.

On the other hand, a method of urging residents to declare a feeling of warmth and coldness when the number of declarations is small (see, for example, Patent Document 2) has been proposed, but the urging of declarations does not always collect a sufficient number of declarations. .. For example, there are cases where residents cannot use the filing terminal due to reasons such as being busy / cannot take their hands off, and the reality is that it is difficult to meet the conditions for the number of filings that can be fully applied. Therefore, it may not be possible to reflect the actual state of the resident's feelings in the living environment evaluation. Therefore, improvement is required.

The present invention has been made to solve such a problem, and the purpose of the present invention is to reflect the actual state of resident's feelings in the living environment evaluation even if a sufficient number of declarations are not collected. It is to provide a hot / cold feeling reporting information processing device and a method capable of the above.

In order to achieve such an object, the present invention is a declaration information acquisition unit that acquires a hot / cold feeling declaration from a resident (101) of the evaluation target space (100) as declaration information including the declaration date and time and the filer ID. From (1), the measurement information acquisition unit (2) that acquires the environmental measurement value of the evaluation target space as measurement information, the declaration information acquired by the declaration information acquisition unit, and the measurement information acquired by the measurement information acquisition unit. , Data integration unit (3) that generates integrated information that associates the declaration date and time, the filer ID, the warm / cold feeling declaration, and the environmental state quantity required from the measurement information, and the integration generated by the data integration unit. It is equipped with a modeling information generation unit (4) that generates modeling information that associates the environmental state quantity with the dissatisfaction level of the resident in the evaluation target space from the information, and the modeling information generation unit is the filer obtained from the integrated information. In relation to the amount of environmental condition for each ID and the amount of hot and cold feeling, when evaluating the hot and cold feeling declaration, the environmental condition on the hotter side than the amount of environmental condition on the coldest side that was declared hot When evaluating the warm / cold feeling report on the cold side, assuming that there was a continuous hot declaration in terms of quantity, the environment on the cold side is larger than the environmental condition on the hottest side where the cold side was declared. It is characterized in that the degree of dissatisfaction of the occupants in the evaluation target space corresponding to the environmental condition amount is calculated by assuming that there has been a continuous cold declaration even in the state quantity.

In the present invention, the declaration information acquisition unit acquires the hot / cold feeling declaration (“hot / cold” declaration) from the resident of the evaluation target space as the declaration information including the declaration date and time and the filer ID, and the measurement information acquisition unit. Acquires environmental measurement values (measured values such as temperature and humidity) of the evaluation target space as measurement information. The data integration department uses the declaration information acquired by the declaration information acquisition department and the measurement information acquired by the measurement information acquisition department to determine the date and time of the declaration, the filer ID, the warm / cold feeling report, and the environment required from the measurement information. Generates integrated information associated with a state quantity (eg PMV). The modeling information generation unit generates modeling information in which the environmental state quantity and the dissatisfaction level (for example, PPD) of the resident in the evaluation target space are associated with each other from the integrated information generated by the data integration unit.

Here, the modeling information generation unit determines that it is hot when evaluating the hot / cold feeling report on the hot side in relation to the environmental state amount for each filer ID obtained from the integrated information and the hot / cold feeling report. When evaluating the warm / cold feeling declaration on the cold side, assuming that there was a continuous hot declaration even in the environmental condition amount on the hotter side than the environmental condition amount on the coldest side, it is declared cold. The degree of dissatisfaction of the residents in the evaluation target space corresponding to the environmental condition amount, assuming that there was a continuous cold declaration even in the environmental condition amount on the coldest side than the environmental condition amount on the hottest side. Ask for.

In other words, when evaluating the hot / cold feeling report, it is reported that it is hot even if there is no declaration that it is hot in the amount of environmental condition on the hotter side than the amount of environmental condition on the coldest side that was declared hot. The degree of dissatisfaction of the resident in the evaluation target space corresponding to the amount of environmental condition is calculated by regarding each filer as being continuously performed. When evaluating the warm / cold feeling report on the cold side, the declaration that it is cold continues even if there is no declaration that it is cold in the amount of environmental condition on the cold side than the amount of environmental condition on the hottest side that was declared cold. It is considered that this is done for each filer, and the degree of dissatisfaction of the resident in the evaluation target space corresponding to the environmental condition is calculated.

In the above description, as an example, the components on the drawing corresponding to the components of the invention are indicated by reference numerals in parentheses.

As described above, according to the present invention, when evaluating the warm / cold feeling report on the hot side, the environmental state amount on the hotter side is continued even if the environmental state amount on the hottest side is higher than the environmental state amount on the coldest side where the report is hot. When evaluating the warm / cold feeling report on the cold side, assuming that there was a report that it was hot, the environment on the cold side is larger than the environmental condition on the hottest side that was declared cold. As for the amount of condition, it was considered that there was a continuous cold declaration for each filer, and the degree of dissatisfaction of the residents in the evaluation target space corresponding to the amount of environmental condition was calculated, so the number of declarations was sufficient. Even if you do not gather, it is possible to reflect the actual situation of the resident's feelings in the living environment evaluation.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the principle of the present invention will be described before going into the description of the embodiment.

[Principle of invention]
The inventor has a high physiological validity that a person who declares the intention of "hot / cold" in any environment feels hotter / colder when the environment becomes hotter / colder than that environment. I focused on that.

Then, in an environment in which hot / cold discomfort is physiologically enhanced for a resident who has made a hot / cold feeling report (“hot / cold” declaration) in an arbitrary environment, the resident actually makes a hot / cold feeling. By assuming that "hot / cold" declarations are being made continuously even if no impressions have been made, I came up with the idea that the actual feeling of warmth and coldness of the residents can be approached.

For example, in the case of finding the number of dissatisfied people on the hot / cold side, once a "hot / cold" declaration is made, and for residents who are considered to be dissatisfied on the hot / cold side, this hot / cold discomfort is physiologically dissatisfied. In an increasing environment, the "hot / cold" declaration from the resident will be maintained and the resident will continue to be considered a hot / cold dissatisfied person.

Further, in the present invention, if the reliability of the maintained hot / cold feeling report is low, it may be a factor that the evaluation result of the feeling feeling using this hot / cold feeling report and the actual state of the feeling of the resident deviate from each other. The inventor pointed out that in the thermal environment area (weak discomfort area) where hot / cold discomfort is weak, the report of warm / cold feeling is easily affected by temporary psychological / physiological factors such as the mood / physical condition of the resident. I focused on. Then, I came up with the idea that the deviation from the actual situation can be suppressed by excluding the report of warmth and coldness that occurred in the weakly uncomfortable area from the targets to be maintained.

Furthermore, after introducing a system for reporting a feeling of warmth and coldness (a system for reporting a feeling of warmth and coldness), the inventor has an excessive sense of expectation for an environmental control system (air conditioning control, etc.) that utilizes this system (see, for example, Patent Document 3). We focused on the fact that the interest in the unexperienced warm / cold feeling filing behavior acts as a temporary psychological factor, and it is easy for the resident to make a declaration that deviates from the actual warm / cold feeling. In order to suppress the deviation from the actual situation due to this, I came up with the idea of considering the elapsed time after the introduction of the hot and cold feeling reporting system as an exclusion condition from the target to be maintained.

[Embodiment 1: Basic Method of Declaration Latch Method]
In the first embodiment, in an environment in which hot / cold discomfort is physiologically enhanced for a resident (reporter) who has made a hot / cold feeling report (“hot / cold” report) in an arbitrary environment, Even if the resident does not actually declare "hot / cold", it is considered that the "hot / cold" declaration is being made continuously, and modeling information (environmental condition amount and corresponding dissatisfaction level) Information) to be generated.

In other words, when evaluating the hot and cold feeling report, it is said that there was a declaration that it was continuously hot even in the hotter side of the environmental condition than the coldest side of the environmental condition that was declared hot. When evaluating the warm / cold feeling report on the cold side for each filer, it is declared that it is continuously cold even in the cold side environmental condition amount than the hottest side environmental state amount in which the cold side was declared cold. It is considered that there was a problem for each filer, and the degree of dissatisfaction of the resident in the evaluation target space corresponding to the environmental condition is calculated.

Below, in any air-conditioned space in a building shared by multiple residents, a model of dissatisfaction (dissatisfaction) determined by the amount of environmental conditions based on the report of warmth and coldness collected from the residents during a predetermined period. The present invention will be described with an example of identifying a function).

[Explanation of dissatisfaction, environmental state quantity, dissatisfaction model (dissatisfaction function)]
The degree of dissatisfaction is a quantity indicating the degree of dissatisfaction of the resident corresponding to the amount of thermal environmental conditions in the room, and indicates the number of dissatisfied persons or an index calculated from the number of dissatisfied persons (such as the dissatisfied person rate). The environmental state quantity is the value itself of environmental factors such as air temperature, radiation temperature, humidity, and wind speed, or a general thermal environmental index calculated using these, for example, operating temperature, SET * (Standard new). Effective Temperature), PMV (Predicted Mean Vote), etc. are shown. PMV is internationally standardized by ISO-7730, and SET * is defined by the American Society of Heating, Refrigerating and Air-Conditioning Association (ASHRAE) standard. Operative temperature is also a general-purpose index.

For example, PMV includes the amount of metabolism and clothing related to the thermal environmental factors (calorific value and heat insulating properties) of the human body, and the air temperature, radiation temperature, humidity, and wind speed, which are environmental factors related to heat transfer such as heat dissipation to the surroundings. It is an index calculated from the above 6 factors and quantified by relating the state of heat balance between the human body and the surrounding environment to the feeling of warmth and coldness of the person. PMV is defined between -3 and +3, and PMV = 0 is the thermal neutral point of the human body, which is in thermal equilibrium with the surrounding environment. As for the feeling, the heat radiation from the human body is larger toward the hot side and the minus side, that is, the environment on the cold side is shown as the feeling of warmth and coldness.

Further, the predicted dissatisfaction rate PPD (Predicted Percentage Dissatisfied) calculated from the value of PMV is shown by the following relational expression as a function of PMV (see FIG. 1). This corresponds to the dissatisfaction model (dissatisfaction function) of the present invention.
PPD = F (PMV)
= 100-95 × exp (−0.03353 × PMV ⁴ −0.2179 × PMV ² ) [%] ・ ・ ・ (1)

Residents' dissatisfaction with the thermal environment on the hot / cold side is due to the feeling of warmth and coldness determined by the transfer of thermal energy between the human body and the surrounding environment. If the hot side is more dissatisfied and the thermal environmental condition is on the side that promotes heat dissipation, the cold side is more dissatisfied.

Therefore, in addition to general indicators such as PMV and PPD, for example, a function of V-shaped dissatisfaction distribution that associates the actual environmental state quantity with the dissatisfaction of the resident may be defined, or the hot side. A function that separates the dissatisfaction on the cold side from the cold side and shows the value in the range of 0-100% with an S-shaped curve that inputs the environmental state quantity is the dissatisfaction model on the hot side / cold side (dissatisfaction) It can also be defined as a degree function). An example thereof is shown in FIG. 2 (see, for example, Patent Document 4). Such a one-sided function includes, for example, a sigmoid function.

In the present embodiment, the dissatisfaction model PD = G (PMV) is identified, where the environmental state quantity is PMV and the dissatisfaction is the dissatisfaction reporter rate PD on the hot side. In the present invention, the function of the dissatisfaction model may be the general model as described above, and a general-purpose optimization method such as the least squares method may be used for model identification. The present invention focuses on the fact that it is physiologically valid for a person who declares "hot / cold" in any environment to feel hotter / colder when the environment becomes hotter / colder than that environment. It is an invention relating to the processing of the warm / cold feeling report information, which makes it easy to reflect the actual state of the resident's feeling in the living environment evaluation.

<Explanation of Data Integration Department>
[Calculation of environmental state quantity PMV]
In the present embodiment, the modeling period is specified at the time of execution by the modeling executor (solution provider for indoor environment evaluation / control, etc., or equipment manager). The modeling period of this embodiment is set to "2016/8 / 1-8 / 31".

The data integration unit 3 acquires the declaration information and the measurement information of the modeling period from the declaration information acquisition unit 1 and the measurement information acquisition unit 2. In this case, the modeling period may be sent to the acquisition units 1 and 2 together with the information transmission request to acquire the data limited to the period from the acquisition units 1 and 2, or the data is held by the acquisition units 1 and 2. After acquiring all the existing data, the data integration unit 3 may delete the data outside the modeling period.

Then, the data integration unit 3 calculates the environmental state quantity for each measurement date and time with respect to the measurement information as shown in FIG. 6, and holds it as the environmental information (measurement date and time, environmental state quantity). Information such as calculation formulas and parameter values required for calculating the environmental state quantity is preset by the solution provider such as indoor environment evaluation / control and the equipment manager.

Since the environmental state quantity of this embodiment is PMV which is internationally standardized as ISO-7730, the calculation method of this standard may be followed, but the calculation is obtained by using the following formula (2). The calculation program is published in "ANSI / ASHRAE Standard 55-2010" and so on.

PMV = G (M) x L ... (2)
However,
G (M) = 0.303 x exp (-0.036 x M) +0.028
L: Heat load on the human body [W / m ² ] = M- (C + R + Ed + Es)-(Cre + Ere)
M: Metabolic equivalent [met]
The following three equations are convergently calculated to calculate C and R.
C: Convection heat loss [W / m ² ] = fcl × hc × (tcl−ta)
R: Radiation heat loss [W / m ² ] = 3.96 × 10 ^-8 × fcl × {(tcl ＋ 273.15) ⁴ − (tr ＋ 273.15) ⁴ }

Icl: Clothes amount [clo]
tr: Average radiation temperature [° C]
ts: Average skin temperature [° C] = 35.7-0.028 × (MW)
W: Mechanical work [W / m ² ] (usually 0)
hc: Convective heat transfer coefficient of the human body [W / m ² ° C]
2.38 × | tcl−ta | ^0.25 or 12.1 × √v The larger of
v: Airflow velocity [m / s]

Cre: Sensible heat loss due to respiration [W / m ² ] = 0.0014 × M × (34-ta)
Ere: Latent heat loss due to respiration [W / m ² ] = 0.0173 × M × (5.87-pa)
pa: Water vapor pressure

In addition, the data integration unit 3 has the following conditions as information necessary for PMV calculation other than the measurement information (air temperature Ta [° C.], humidity H [%]) acquired from the measurement information acquisition unit 2. Is preset. In the following, the radiation temperature Tr is set to use a value equal to the air temperature Ta in the measurement information.
Average radiation temperature Tr [° C] = Air temperature Ta [° C], wind speed 0.1 [m / s], metabolic rate 1.0 [met], clothing amount 0.8 [clo]

[Generation of integrated information (declaration date and time, filer ID, warm / cold feeling report V, environmental condition amount)]
The data integration unit 3 extracts the environmental state quantity of the measurement date and time corresponding to the declaration date and time of the declaration information and integrates it into the declaration information. FIG. 7 shows an example of integrated information.

The environmental state quantity may be calculated by first extracting the measurement information of the measurement date and time corresponding to the declared date and time and performing only on this measurement information. Further, when the time interval is different such that the resolution of the declaration date and time is in units of 1 minute and the measurement cycle of measurement information is in units of 10 minutes, the solution provider or the equipment manager may determine the corresponding rule in advance. for example,. .. 14:50, 15:00, 15:10 ,. .. For the measurement information measured every 10 minutes, the latest measurement information at 15:00 or 15:10, which is advanced in 10-minute units, is used as the measurement information corresponding to the declared date and time of 15:03. Just leave it.

<Explanation of operation of modeling information generator>
The modeling information generation unit 4 generates data of the environmental state quantity and the corresponding dissatisfaction degree from the acquired integrated information, and transmits it to the modeling unit 5 as modeling information.

The modeling information of this embodiment is (PMV, the complaint rate PD on the hot side corresponding to PMV). Further, the dissatisfaction reporter rate PD in any PMV is a value calculated from the number of dissatisfied reporters in any PMV / the number of residents in the evaluation target space N_all, and the number of residents N_all in the evaluation target space is the indoor environment. It is preset by the solution provider for evaluation / control and the equipment manager.

The modeling information generation unit 4 calculates the following characteristic dissatisfaction filers.
FIG. 8 shows the occurrence status of PMV and the corresponding “hot” declaration by separating the integrated information of FIG. 7 for each filer ID. From this data, the number of complaints on the hot side (the number of “hot” filers) for PMV is calculated as shown in FIG. Here, if the warm / cold feeling report includes the above-mentioned stepwise expression, the stage of the report to be regarded as the dissatisfied filer on the hot side may be determined in advance.

In FIG. 9, it can be confirmed that the number of “hot” filers decreases even if the PMV increases, that is, even if the thermal environment changes to the physiologically hot side environment. However, it is physiologically valid for a person who declares "hot / cold" in any environment to feel hotter / colder if the environment becomes hotter / colder than that environment. Residents usually stay in the building for activities other than warm / cold reporting, and even if they feel hot, they do not report hot / cold feeling, for example, because they are busy / cannot take their hands off. / It is thought that there are cases where it cannot be done.

Therefore, in the present invention, it is considered that the declaration is continued even if the hot / cold feeling declaration is not actually made, that is, when the hot / cold feeling declaration is evaluated for each filer. , When evaluating the warm / cold feeling report on the cold side, it is considered that there was a continuous hot report even on the hotter side of the environmental condition than on the coldest side where it was declared hot. By assuming that there was a continuous cold declaration even in the coldest environmental condition than the hottest environmental condition in which it was declared cold, the dissatisfaction level was calculated and used as modeling information. Suppress the discrepancy between the hot and cold feeling report information and the actual state of the resident's feelings. For example, when evaluating the hot and cold feeling report, maintain a "hot" declaration for each filer with the amount of environmental condition on the hotter side than the amount of environmental condition on the coldest side that was declared hot (specifically). When evaluating the warm / cold feeling declaration on the cold side, the filer declares "cold" with the environmental condition amount on the cold side rather than the environmental condition amount on the hottest side that was declared cold. The degree of dissatisfaction is calculated by maintaining each time (latch as a specific processing example). Such a process is referred to as a "declaration latch process" in the present specification, and will be described in the present embodiment. In the present embodiment, the example of evaluating the hot / cold feeling report on the hot side will be described, but the same can be achieved when evaluating the hot / cold feeling report on the cold side.

An image of the data of FIG. 8 after the declaration latch processing is performed is shown in FIG. Latch the smallest PMV (the thermal environment on the side where the hot discomfort is weak, that is, the cold side) where each filer made a "hot" declaration Start point PMV start (n) (n is a positive integer, in this embodiment) n = 1 to 4), and in the PMV region (thermal environment on the hot side) larger than this, the “hot” declaration generation state is maintained. That is, it is considered that the PMV on the hotter side than the PMV on the coldest side, which was declared hot, was continuously declared to be hot. As a result, as shown in FIG. 11, the number of “hot” filers after the filing latch process increased as the environment became hotter, and the thermal environment changed to the physiologically hot side. However, in principle, the PMV region where the number of "hot" filers decreases does not occur.

FIG. 12 shows a processing flow of the declaration latch processing in the modeling information generation unit 4.
After excluding the information in the integrated information that is not the target of the modeling information (step S101), the modeling information generation unit 4 obtains the number N_vote of the filer IDs included in the integrated information (step S102). In the data example shown in FIG. 7, the declarations other than “hot” (hot) are excluded from the integrated information, and the number of filer IDs N_vote = 4 is obtained.

Then, the modeling information generation unit 4 starts the process of the filer ID = Pn with n = 1 (n is a positive integer less than or equal to N_vote) (step S103).

In this processing of the filer ID = Pn, the minimum value PMV start (n) of the PMV when the report that it is hot is obtained from the environmental state quantity PMV when the reporter ID = Pn “hot” is generated, and the filer The latch start point of ID = Pn is set (step S104).

Then, it is confirmed whether the processing of all filers has been completed (step S105), and if the processing of all filers has not been completed (NO in step S105), n = n + 1 (step S106), and the following The operation of obtaining PMV start (n) for the filer ID is repeated (steps S104 to S106).

In this way, after obtaining the PMV start (n) of all the filers (YES in step S105), the modeling information generation unit 4 models the information of the PMV and the corresponding dissatisfied reporter rate PD on the hot side. (Step S107).

The state V_latch (n) (1: yes or 0: no) of the filer Pn for any PMV is expressed by the following equation (3).

Then, the dissatisfaction reporter rate PD on the hot side for any PMV is calculated by the following equation (4).

FIG. 13 shows an example of modeling information when N_all is 10 [people] with respect to the data of FIG. The PMV step of the modeling information transmitted to the modeling unit 5 may be constant or irregular, but it is generally sufficient if the PMV point where PD increases is included. In any case, the processing of the modeling information generation unit 4 obtains the relational information between the environmental state quantity and the dissatisfaction degree based on the measurement information and the declaration information, and transmits the information to the modeling unit 5.

The calculation method of this embodiment is an example. Consider a "hot / cold" hot / cold feeling filer as a hot / cold side dissatisfaction, and in an environment that physiologically enhances this hot / cold discomfort, consider this filer as a hot / cold side dissatisfaction. Needless to say, the method of maintaining the state and obtaining the result of calculating the dissatisfaction degree is not limited to the present embodiment.

<Explanation of the operation of the modeling section>
In the modeling unit 5, the model function and search parameters of the dissatisfaction model and the optimization method to be used are preset by the solution provider such as indoor environment evaluation / control and the equipment manager.

The modeling unit 5 searches for search parameters and identifies a model by using the modeling information acquired from the modeling information generation unit 4.

The model function includes constants A, B, C, D, and E (for example, as shown in equation (1)'following based on the relational expression between PMV and predicted dissatisfaction rate PPD in equation (1) described above. A + B = 100) may be used as a search parameter, or U and V in Eq. (5) shown below based on the sigmoid function may be used as search parameters, and the solution provider or equipment manager may set them as appropriate. As the optimization method, a general-purpose method such as the least squares method or the simplex method may be used.

As described above, by applying the declaration latch processing having high physiological validity, it is possible to bring the warm / cold feeling declaration information with respect to the environmental condition amount closer to the actual state of the resident's feeling. The indoor environment evaluation and dissatisfaction model based on this can also be made closer to the feeling of the resident.

[Embodiment 2: Improved method 1 of the first embodiment (exclusion from maintenance target by dead zone)]
In the method described in the first embodiment, the importance of maintaining the hot and cold feeling report is high, and if the reliability of this report is low, it may cause a deviation from the actual state of the resident's feelings.

A hot / cold feeling report in a thermal environment area (weak discomfort area) where hot / cold discomfort is weak is susceptible to temporary psychological / physiological factors such as the filer's mood / physical condition. Therefore, in the second embodiment, the weak discomfort zone is set as the filing dead zone, and the warm / cold feeling filing in the filing dead zone is excluded from the declarations to be maintained, thereby suppressing the deviation from the actual situation.

That is, when evaluating the hot / cold feeling report, a predetermined area (weakly uncomfortable area) of the amount of the environmental state on the cold side is used, and when evaluating the hot / cold feeling report on the cold side, the environmental state on the hot side is used. A predetermined area (weakly uncomfortable area) of the amount is set as a dead zone area, and the declaration of this dead zone area is excluded, and the degree of dissatisfaction of the resident in the evaluation target space corresponding to the environmental state quantity is calculated.

The configuration of the present embodiment is the same as that of FIG. 4, and only the setting information held by the modeling information generation unit 4 and the operation corresponding to step S104 shown in FIG. 12 are different. Since the other parts are the same as those in the first embodiment, only the different parts will be described.

In the modeling information generation unit 4, the declaration dead zone, which is the exclusion range of the maintenance target, is preset as the range of the environmental state amount by the solution provider such as indoor environment evaluation / control and the equipment manager. In the present embodiment, this range is set to −0.3 ≦ PMV ≦ + 0.3.

At this time, when the latch start point PMV start (n) in step S104 shown in FIG. 12 is obtained, the declaration in the declaration dead zone −0.3 ≦ PMV ≦ + 0.3 is excluded and the latch start point PMV start ′ with dead zone is excluded. Find n).

Fig. 14 shows an image of the occurrence of "hot" declarations due to the declaration latch processing when the declaration dead zone is applied to the integrated information similar to the first embodiment, and corresponds to the amount of environmental conditions and the number of "hot" filers. Is shown in FIG. FIG. 14 shows only the dead zone on the plus side as the declared dead zone.

It should be noted that this improved method is a process of excluding the declarations in the dead zone area, and the number of filers in the PMV area in the dead zone area is not necessarily set to 0 in the calculation of the number of filers. It is appropriate that the PMV region corresponding to the dead zone region is excluded from the calculation of the number of filers and the degree of dissatisfaction (see FIG. 15).

As described above, in the second embodiment, the filing insensitivity zone, which is regarded as a weakly uncomfortable area, is introduced, and the warm / cold feeling filing, which is assumed to be unreliable, is excluded from the maintenance target, so that the actual state of the resident's feelings is realized. Suppress the divergence with. Note that the exclusion of the declaration in the filing dead zone may be a process of excluding the declaration in the filing dead zone in advance in S101 instead of the process in S104 described above.

[Embodiment 3: Improved method 2 of the first embodiment (exclusion from maintenance target due to elapsed time after introduction of hot / cold feeling reporting system)]
In the method described in the first embodiment, the importance of maintaining the hot and cold feeling report is high, and if the reliability of this report is low, it may cause a deviation from the actual state of the resident's feelings.

After the introduction of the warm / cold feeling reporting system, expectations for the system and interest in unexperienced warm / cold feeling reporting behavior acted as temporary psychological factors, and reports that deviated from the actual feeling of warmth and coldness of residents. It is more likely to occur.

Therefore, in the third embodiment, the hot / cold sensation report generated within a certain period after the introduction of the hot / cold sensation report system to which the hot / cold sensation report information processing device 200 is applied is excluded from the report to be maintained. Suppress the divergence with. In other words, after the introduction of the hot / cold feeling report system, the hot / cold feeling report filed by the time a predetermined time elapses is excluded, and the degree of dissatisfaction of the resident in the evaluation target space corresponding to the environmental condition is calculated. , Try to suppress the deviation from the actual situation.

The configuration of the present embodiment is the same as that of FIG. 4, and only the setting information held by the modeling information generation unit 4 and the operation corresponding to step S104 shown in FIG. 12 are different. Since the other parts are the same as those in the first embodiment, only the different parts will be described.

In the modeling information generation unit 4, the introduction date and time Ts of the hot / cold feeling reporting system and the declaration latch target exclusion period D are preset by the solution provider for indoor environment evaluation / control and the facility manager. The declaration latch target exclusion period D is set to, for example, 72 hours (3 days) or 168 hours (7 days). In the present embodiment, the introduction date / time Ts and the declaration latch target exclusion period D are used, but of course, the start date / time and the end date / time to be excluded may be specified.

At this time, as a process for obtaining the latch start point PMVstart (n) in step S104 shown in FIG. 12, the declaration date and time is referred to from the integrated information for the declaration as a candidate for PMVstart (n). At this time, if multiple declarations occur for the same environmental condition amount, all the declaration dates and times are referred to.

Then, for each declaration, the elapsed time Te after the introduction is obtained from the declaration date and time and the introduction date and time Ts, and when Te ≦ D, this declaration is excluded and the next latch start point is searched. This is repeated until PMVstart (n) for which Te> D is found, and the elapsed time-considered latch start point PMVstart'' (n) is set.

As described above, in the third embodiment, the resident's warm / cold feeling report is excluded from the maintenance target in consideration of the elapsed time after the introduction of the hot / cold feeling report system. Suppress the deviation from the actual feeling. In addition, the exclusion of the declaration in the declaration exclusion period may be a process in which the declaration in the declaration exclusion period is excluded in advance in S101 instead of the process in S104 described above.
