These programs are loaded from the auxiliary storage device 903 into the main storage device 902. Then, the processor 901 executes these programs to perform operation of the communication part 701, the input part 702, the model generating part 703, the temperature distribution estimating part 704, the position deciding part 705, the model correcting part 706, the replacement candidate extracting part 707, and the output part 708 which will be described later.
In
The input part 702 can acquire at least the part of the input data illustrated in
The model generating part 703 generates the analysis model for the airflow analysis of the freezing warehouse 3. More specifically, the model generating part 703 generates the analysis model that reflects the data of: the operation data of the freezing apparatus; the size and shape of the freezing warehouse 3; the heat insulating performance of the walls of the freezing warehouse 3; the position of the door in the freezing warehouse 3; and the identifier, the specifications, and the position of the freezing apparatus.
A method for generating the analysis model is not particularly specified. The model generating part 703 may generate the analysis model according to an existing method.
The temperature distribution estimating part 704 performs the airflow analysis of the freezing warehouse 3 by using the analysis model generated by the model generating part 703, and estimates the temperature distribution in the freezing warehouse 3.
Further, the temperature distribution estimating part 704 performs the airflow analysis of the freezing warehouse 3 by using the analysis model which is after being corrected by the model correcting part 706 which will be described later, and estimates the temperature distribution in the freezing warehouse 3.
Note that, a method for the airflow analysis is not particularly specified. The temperature distribution estimating part 704 may perform the airflow analysis according to an existing method.
The position deciding part 705 analyzes the temperature distribution estimated by the temperature distribution estimating part 704 and decides a position of the measurement point.
More specifically, the position deciding part 705 decides as the position of the measurement point, a characteristic point in the temperature distribution estimated by the temperature distribution estimating part 704. The characteristic point is, for example, a point where a highest temperature is estimated in the temperature distribution, a point where a lowest temperature is estimated in the temperature distribution, or the like. Besides, the administrator of the replacement proposing apparatus 7 can arbitrarily decide a condition for the characteristic point.
The model correcting part 706 collates the temperature distribution estimated by the temperature distribution estimating part 704 with the temperature data (the temperature at the measurement point) acquired by the communication part 701, and corrects the analysis model based on the collation result.
For example, when there is a difference between the temperature at the measurement point in the temperature distribution and the temperature at the measurement point in the temperature data, the model correcting part 706 corrects the analysis model so as to cancel the difference.
The replacement candidate extracting part 707 extracts the replacement candidate for the freezing apparatus based on the temperature distribution estimated by the temperature distribution estimating part 704, which is obtained by the airflow analysis using the analysis model after correction.
Further, the replacement candidate extracting part 707 also generates a placement candidate of the extracted replacement candidate.
Further, the replacement candidate extracting part 707 can calculate a difference, that is the energy saving effect, between power consumption by the current freezing apparatus and power consumption when the replacement candidate is placed at the placement candidate in the freezing warehouse 3. Further, the replacement candidate extracting part 707 does not have to generate the placement candidate. In this case, the replacement candidate extracting part 707 calculates a difference between the power consumption by the current freezing apparatus and power consumption when the replacement candidate is placed at the same position as the current freezing apparatus.
Further, the replacement candidate extracting part 707 may make a proposal for changing placement of the current freezing apparatus without extracting the replacement candidate.
The output part 708 presents (outputs) the output data illustrated in
Next, an operation example of the replacement proposing apparatus 7 according to the present embodiment will be described with reference to
First, in step S101, the communication part 701 acquires the input data in
Next, in step S102, the model generating part 703 generates the analysis model.
Specifically, the model generating part 703 generates the analysis model by using the input data in
The model generating part 703 outputs the generated analysis model to the temperature distribution estimating part 704 and the model correcting part 706.
Next, in step S103, the temperature distribution estimating part 704 performs the airflow analysis by using the analysis model generated in step S101. As described above, the temperature distribution estimating part 704 can perform the airflow analysis according to an arbitrary method.
The temperature distribution estimating part 704 outputs data of the temperature distribution in the freezing warehouse 3 obtained by the airflow analysis to the position deciding part 705 and the model correcting part 706.
Next, in step S104, the position deciding part 705 decides the position of the measurement point.
The position deciding part 705 decides as the position of the measurement point, for example, a position corresponding to the characteristic point in the temperature distribution in the freezing warehouse 3. As described above, the characteristic point is, for example, the point where the highest temperature is estimated in the temperature distribution, the point where the lowest temperature is estimated in the temperature distribution, or the like.
The position deciding part 705 outputs to the output part 708, position data indicating the position of the measurement point.
The output part 708 presents (outputs) to the administrator of the replacement proposing apparatus 7, the position data which is from the position deciding part 705. Then, the administrator of the replacement proposing apparatus 7 requests, for example, a user of the freezing warehouse 3 to place the temperature measuring apparatus 4 at the measurement point. The user of the freezing warehouse 3 places the temperature measuring apparatus 4 at the measurement point according to the position data.
Further, the position deciding part 705 may output the position data to the communication part 701, and the communication part 701 may transmit the position data to a terminal apparatus used by the user of the freezing warehouse 3. Also, in this case, the user of the freezing warehouse 3 places the temperature measuring apparatus 4 at the measurement point according to the position data. A notification of the position data to the user of the freezing warehouse 3 may be performed according to a method other than these.
Next, in step S105, the communication part 701 acquires from the collecting apparatus 5, the temperature data indicating the temperature measured by the temperature measuring apparatus 4 at the measurement point.
The communication part 701 outputs acquired temperature data to the model correcting part 706.
Note that, in addition to step S101, the communication part 701 may acquire the operation data of the freezing apparatus at this stage (step S105). When the communication part 701 acquires the operation data, the communication part 701 outputs the acquired operation data to the model correcting part 706.
Next, in step S106, the model correcting part 706 corrects the analysis model.
Specifically, when there is the difference between the temperature at the measurement point in the temperature distribution generated by the temperature distribution estimating part 704 and the temperature at the measurement point in the temperature data, the model correcting part 706 corrects the analysis model so as to cancel the difference.
Further, when the operation data of the freezing apparatus is acquired in step S105, the model correcting part 706 may correct the analysis model by using the operation data.
The model correcting part 706 corrects the analysis model while changing various types of parameters of the analysis model, for example, by a trial-and-error method so as to cancel the difference described above.
The model correcting part 706 outputs to the temperature distribution estimating part 704, the analysis model after correction.
Next, in step S107, the temperature distribution estimating part 704 performs the airflow analysis by using the analysis model after correction.
The airflow analysis performed in step S107 differs only in that the analysis model after correction is used, and a procedure itself of the airflow analysis is the same as the airflow analysis in step S103.
In the airflow analysis in step S107, the temperature distribution in the freezing warehouse 3 can be obtained, which is closer to a current state than the airflow analysis in step S103 is.
The temperature distribution estimating part 704 outputs to the replacement candidate extracting part 707, the data of the temperature distribution in the freezing warehouse 3 obtained from the airflow analysis.
Next, in step S108, the replacement candidate extracting part 707 extracts the replacement candidate based on the data of the temperature distribution obtained in step S107, The auxiliary storage device 903 illustrated in
The replacement candidate extracting part 707 extracts, for example, a problem in a current temperature distribution, and extracts as the replacement candidate, a freezing apparatus necessary for solving the extracted problem. The replacement candidate extracting part 707 extracts as the problem, for example, a spot whose temperature is high because the air flow does not reach, a spot which is too cold, an imbalance in the temperature distribution in the freezing warehouse 3, or the like.
Further, the replacement candidate extracting part 707 also generates the placement candidate of the extracted replacement candidate. More specifically, the replacement candidate extracting part 707 generates one of a first placement candidate where the replacement candidate is placed according to a current placement of the freezing apparatus, and a second placement candidate where the replacement candidate is placed differently from the current placement of the freezing apparatus. For example, the replacement candidate extracting part 707 requests the temperature distribution estimating part 704 for the air flow analysis in a case where the replacement candidate is placed according to the current placement of the freezing apparatus. Then, the replacement candidate extracting part 707 compares the temperature distribution obtained by a newly performed airflow analysis with the temperature distribution obtained by the airflow analysis in step S107. When there is a significant difference between the two temperature distributions, the replacement candidate extracting part 707 selects the first placement candidate. On the other hand, when there is no significant difference between the two temperature distributions, the replacement candidate extracting part 707 selects the second placement candidate. Note that, a specific definition of the “significant difference” is decided by the administrator of the replacement proposing apparatus 7. When the second placement candidate is selected, the replacement candidate extracting part 707 tries various types of positions for the replacement candidate by the trial-and-error method, and adopts a placement candidate at which a significant difference is obtained in the temperature distribution.
Further, the replacement candidate extracting part 707 calculates a difference (energy saving effect) between the power consumption by the current freezing apparatus and the power consumption when the replacement candidate is placed in the freezing warehouse 3.

As described above, in the present embodiment, the temperature distribution obtained by the airflow analysis using the analysis model and the temperature actually measured at the measurement point are collated with each other, and the analysis model is corrected based on the collation result. Therefore, according to the present embodiment, it is possible to obtain an accurate temperature distribution by performing the airflow analysis using the corrected analysis model. Further, since the accurate temperature distribution can be obtained, it is possible to extract an appropriate replacement candidate.
As a result, according to the present embodiment, it is possible to avoid increase in energy consumption due to occurrence of an overcooled place, deterioration in quality of a stored product due to occurrence of an uncooled place, mismatch in a capacity of the freezing apparatus, and the like.
Further, in the present embodiment, since an improvement status of the temperature distribution can be presented in a for that one can easily recognize the improvement status, it is possible to improve a proposal ability.
Note that, although the freezing apparatus placed in the freezing warehouse 3 has been described above, the indoor space is not limited to the freezing warehouse 3, and also, the temperature adjusting device placed in the indoor space is not limited to the freezing apparatus.
