Next, a supply temperature control method for changing the setting of the hot water supply temperature supplied from the hot water supply temperature control device of the building energy management system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart illustrating a hot water temperature control method in a building energy management system according to an exemplary embodiment of the present invention.

First, the hot water supply temperature control device 100 monitors the main monitoring items of the boiler system 10 in real time through various sensors and measuring instruments installed in the boiler system 10, and stores the monitoring results and manages them as statistical data.

In the embodiment of the present invention, the hot water supply temperature control apparatus 100 receives the hot water flow rate supplied from the hot water tank 11 and monitors each used place to collect the hot water consumption amount and the hot water use temperature of each used place, and collect the monitoring information. (Hot water consumption, hot water use temperature) is stored and managed by statistical data.

Referring to FIG. 3, in operation 1101, the hot water supply temperature control apparatus 100 confirms an appropriate supply hot water supply temperature provided according to a hot water use place and a use purpose currently managed by a manager. At this time, the hot water supply temperature control device 100 also checks the set temperature of the hot water tank currently set in the building.

Next, in step 1102, the hot water supply temperature control apparatus 100 compares the monitored information with the hot water supply temperature and the appropriate supply hot water supply temperature for each actual use place to identify the place where the oversupply occurs.

In operation 1103, the hot water supply temperature control apparatus 100 determines whether it is necessary to change the set value of the hot water supply temperature supplied to the identified use places where the oversupply occurs. That is, the hot water supply temperature control apparatus 100 checks the proper use temperature of the use place with the highest predetermined use temperature among the identified use places, and checks whether the confirmed proper use temperature is lower than the hot water supply temperature supplied.

As a result of the check, when it is necessary to change the set value of the hot water supply temperature, in step 1104 the hot water supply temperature control device 100 performs the hot water temperature control for changing the hot water temperature set value.

Specifically, first, the control unit 130 derives a first control value for changing the set value of the hot water supply temperature supplied to the corresponding use destination, which is primarily confirmed according to the use place and the use purpose through the simulation. Next, the controller 130 checks the hot water consumption and hot water temperature by the corresponding user through analysis by period (day / day / season) using the accumulated statistical data to determine the hot water consumption temperature and the average hot water temperature value according to the hot water temperature. By deriving the average hot water temperature value is derived as a second control value. For example, if the average value of the supplied hot water supply temperature for each period is derived to 60 ° C through the statistical data, the second control value may be set to 60 ° C. In addition, the controller 130 may derive the second control value according to the site by using statistical data similar to the first control value.

Finally, in order to set the optimum hot water temperature, the controller 130 corrects the second control value by using the monitoring information obtained through real-time monitoring and the proper supply hot water temperature confirmed in step 1101 to set the final control value. For example, if the monitored hot water usage is about 10% excess, the final control value is set at 55 to 59 ° C. In addition, the final control value may be set to a change temperature value corresponding to 10% according to a preset table value for the change temperature for each usage amount.

Accordingly, the hot water supply temperature control device 100 performs a control for changing the supply hot water temperature of the use place identified as the final control value.

Thereafter, in step 1105, even if the hot water supply temperature control device 100 directly controls or does not control the boiler system 20, the hot water supply temperature control device 100 may request a job for the hot water supply temperature control. The hot water supply temperature control apparatus 100 may generate work request information and transmit the generated work request information to the manager. The administrator applies the work request information to control a plurality of boiler systems to change the optimal hot water temperature, that is, the set value of the hot water temperature supplied to the user where the excess occurs according to the final control value.

In operation 1106, the hot water supply temperature control device 100 checks whether an alarm has occurred in the boiler system 10 according to a preset and registered alarm item. For example, such an alarm may occur if the monitored supply hot water temperature falls below the set point for each application.

As a result of the check, if an alarm occurs, the hot water supply temperature control apparatus 100 proceeds to step 1104 to perform hot water temperature control again.

On the other hand, if the alarm does not occur for a predetermined period, in step 1107 the hot water supply temperature control device 100 analyzes the monitoring result to check the energy consumption, and confirm the energy saving degree through the confirmed energy consumption. To this end, the hot water supply temperature control device 100 may generate and manage the energy saving result report data (per day / month / day / year / year / quarter / half year / season). The hot water supply temperature control device 100 transmits the energy saving report data generated in this way to the manager. This allows managers to review energy savings reporting data or request further work.

Therefore, when a work request (request according to a review result or a request for additional work) according to the energy saving report data is made from the manager, the control unit 130 of the hot water supply temperature control device 100 provides information on the result of the review or additional work. You can register as an example of a saving item.

On the other hand, the hot water supply temperature control device 100 may determine the energy consumption by analyzing the effect through the real-time monitoring result information of the boiler system 10. To monitor the energy savings according to the identified energy consumption, compare the monitoring data of the energy saving confirmation items for each boiler operation time, each boiler load rate and fuel usage with the historical data for year / quarter / half year / month / day / day Analysis can confirm energy savings.
