<Description of processing>
Next, the process performed in the middle water utilization management system 1 which consists of a structure demonstrated above is demonstrated.

  FIG. 12 shows the control of the electromagnetic valve 45 according to the reservation contents managed by the reservation information database 220 performed by the medium water supply management unit 207 of the server device 20, and the room water utilization facility 4 from the room temperature medium water tank 41. 5 is a flowchart for explaining processing related to supply of intermediate water or clean water (hereinafter referred to as intermediate water supply processing S1200). The process shown in the figure is executed, for example, when the control timing of the electromagnetic valve 45 has arrived. The process of supplying the intermediate water from the warm intermediate water tank 42 to the intermediate water utilization facility 4 is basically performed in the same flow as the intermediate water supply process S1200. Hereinafter, the intermediate water supply process S1200 will be described with reference to FIG.

  When the control timing of the intermediate water supply process S1200 comes (S1211), the server device 20 determines whether or not the remaining amount of intermediate water stored in the room temperature intermediate water tank 41 is zero (S1212). When the remaining amount is zero (S1212: YES), the server device 20 uses the countermeasure method (contents of reference numeral 1124 in FIG. 11) when there is a shortage of the middle water use facility 4 whose current reservation time is the middle water use facility 4. Obtained from the reservation information database 220 (S1213). And the server apparatus 20 stops supply of a middle water about the middle water utilization facility 4 whose response method at the time of a middle water shortage is "stop" (S1213: Cancel). Further, the server device 20 starts the supply of “water supply” for the water supply facility 4 whose response method when the water supply is insufficient is “water supply” (S1213: water supply) (S1214). When the remaining amount is zero (S1212: YES), the server device 20 controls the pump 44 and the electromagnetic valve 45 to pump the middle water from the middle water storage tank 31 to the room temperature middle water tank 41.

  On the other hand, when the remaining amount of the middle water stored in the room temperature / water tank 41 is not zero (S1212: NO), the server device 20 determines which stage the remaining amount of the room temperature / water tank 41 is currently at. (S1221). Here, the stage refers to a plurality of ranges divided by a predetermined threshold. In the present embodiment, three stages (first stage, second stage, and third stage) are provided, of which the first stage is a range that is greater than or equal to the first threshold value, the second stage is less than the first threshold value, and the second threshold value. The above range, the third stage, is assumed to be a range less than the second threshold and greater than or equal to the third threshold.

  If the remaining amount of the room temperature water tank 41 is in the first stage (S1221: first stage), the server device 20 currently has the use reservation date and time (current is the use reservation time 1126 in FIG. 11). The middle water is supplied from the room temperature middle water tank 41 to all the middle water use facilities 4 included (S1222).

  Also, if the remaining amount of the room temperature water tank 41 is in the second stage (S1221: second stage), the server device 20 currently has the use reservation date and time (current is the use reservation time of 1126 in FIG. 11). The middle water is supplied from the room temperature middle water tank 41 to the middle water utilization facility 4 up to the n-th priority among the middle water utilization facilities 4 included in (S1223).

  If the remaining amount of the room temperature water tank 41 is in the third stage (S1221: third stage), the server device 20 has the current use reservation date and time (current is the use reservation time 1126 in FIG. 11). Among the medium water use facilities 4 included, medium water is supplied from the room temperature medium water tank 41 to the m water use facilities 4 up to the m (<n) th priority (S1224).

  As described above, the supply of the middle water (or the warm water) from the room temperature middle water tank 41 (or the warm water tank 42) to the middle water utilization facility 4 is performed according to the preset reservation status and priority. . Therefore, according to the use needs of the middle water for each middle water utilization facility 4, the middle water can be used efficiently. It should be noted that clean water is appropriately supplied to the intermediate water utilization facility 4 for which supply of intermediate water has been stopped in the above processing.

  FIG. 13 shows the water supply facility 3 and the facility for using the middle water depending on the amount of power generated by the micro hydroelectric generator 34, the meter reading value of the power consumption meter 473, the amount of electricity stored in the power storage device 46, etc. 4 for selecting power to be supplied to the power source 4 (power stored in the power storage device 46, power generated by the micro hydroelectric generator 34, power from the commercial power system, etc.), selling power to the commercial power system, and from the commercial power system 6 is a flowchart for explaining processing related to power purchase control (hereinafter referred to as power control processing S1300). The processing shown in the figure is executed when a preset control timing (at any time, periodically, etc.) has arrived. Hereinafter, the power control process S1300 will be described with reference to FIG.

  When the preset control timing arrives (S1311), the server device 20 determines whether or not there is currently a demand for power in the water supply facility 3 or the water supply facility 4 (S1312). When there is a demand for power (S1312: YES), the process proceeds to S1321, and when there is no demand for power (S1312: NO), the process proceeds to S1341.

  In S1321, the server device 20 determines whether or not the micro hydroelectric generator 34 is currently generating power. If power generation is in progress (S1321: YES), the process proceeds to S1322, and if power generation is not in progress (S1321: NO), the process proceeds to S1325.

  In S1322, the server device 20 determines whether the generated power satisfies the demand (surplus), is not in excess or insufficient, or is insufficient. If it is surplus (S1322: surplus), the process proceeds to S1342, and if it is not excessive or insufficient (S1322: no excess or deficiency), the process proceeds to S1323, and if it is insufficient (S1322: insufficient), the process proceeds to S1325.

  In S <b> 1323, the server device 20 determines to perform control that covers the demand only by the power generation amount of the micro hydroelectric generator 34, and controls the power conditioner 47 and the like to control the demand only by the power generation amount of the micro hydropower generator 34. Execute the control to make it covered. Thereafter, the process returns to S1311 and the server device 20 waits for the next control timing.

  In S1325, the server apparatus 20 determines whether or not the current electricity bill is equal to or less than the power purchase reference value. If the current electricity rate is equal to or less than the power purchase reference value (S1325: YES), the server device 20 determines to perform control to cover the demand only by the purchased power, and controls the power conditioner 47 and the like. Control for changing the demand to be in a state where only the purchased power is covered is executed (S1326). Thereafter, the process returns to S1311 and the server device 20 waits for the next control timing.

  On the other hand, if the current electricity rate is higher than the power purchase reference value (S1325: NO), the server device 2 determines whether or not the demand can be covered only with the power stored in the power storage device 46 (S1327). . When it is determined that the demand can be covered only by the power stored in the power storage device 46 (S1327: YES), the server device 2 performs control to cover the demand only by the power stored in the power storage device 46. The control is performed to control the power conditioner 47 and the like to cover the demand with only the power stored in the power storage device 46 (S1328). Thereafter, the process returns to S1311 and the server device 20 waits for the next control timing.

  On the other hand, when it is determined that the power stored in the power storage device 46 alone cannot cover the demand (S1327: NO), the server device 2 uses the power stored in the power storage device 46 and the purchased power. It is determined to perform control to cover the demand, and the power conditioner 47 and the like are controlled to execute control to cover the demand by the power stored in the power storage device 46 and the purchased power ( S1329). Thereafter, the process returns to S1311 and the server device 20 waits for the next control timing.

  On the other hand, in S1341 branched from S1312, the server apparatus 20 determines whether or not the micro hydroelectric generator 34 is currently generating power. If power generation is in progress (S1341: YES), the process proceeds to S1342. If power generation is not in progress (S1341: NO), the process returns to S1311, and the server device 20 waits for the next control timing to arrive.

  In S <b> 1342, the server device 20 determines whether or not power can be further stored in the power storage device 46. If it is storable (S1342: YES), the server apparatus 2 decides to control the power storage apparatus 46 to store the power generated by the micro hydroelectric generator 34, and controls the power conditioner 47 and the like. Control for setting the power storage device 46 to store the power generated by the micro hydroelectric generator 34 is executed. Thereafter, the process returns to S1311 and the server device 20 waits for the next control timing. On the other hand, if it cannot be stored (S1342: NO), the process proceeds to S1344.

  In S1344, the server apparatus 20 determines whether the power generated by the micro hydroelectric generator 34 can be sold to the commercial power system. If power sale is possible (S1344: YES), the server device 20 determines to perform control to sell the power generated by the micro hydroelectric generator 34, and controls the power conditioner 47 and the like to perform micro hydro power generation. The sale of the electric power generated by the machine 34 is started (S1345).

  On the other hand, if the power cannot be sold (S1344: NO), the server device 20 operates the pumping pump 44 and the heat storage device (heat pump, etc.) using the power generated by the micro hydroelectric generator 34 (load creation). The power generated by the micro hydroelectric generator 34 is effectively used (S1346).

  As described above, the server device 20 determines whether or not there is power demand, the power generation state of the micro hydroelectric generator 34, the current electricity bill of the commercial power system, the power storage state (power storage state) of the power storage device 46, and the commercial power. Supply and use of electric power based on various conditions such as whether or not electric power can be sold. For this reason, the effective use of the electric power generated by the micro hydroelectric generator 34 can be achieved. In addition, it is possible to appropriately perform power sale to the commercial power system and purchase from the commercial power system.

  Further, according to the current output of the micro hydroelectric generator 34, the output of the micro hydroelectric generator 34, the electric power stored in the power storage device 46, and the commercial electric power are appropriately selected as the electric power to be supplied to the power utilization facility. Can do. In addition, since commercial power is selected as the power to be supplied to the power usage equipment only when the electricity price is below the power purchase reference value, the power supply to the power usage equipment is appropriately suppressed while suppressing the amount of power purchased from the commercial power. Can be performed efficiently. Further, when there is a surplus power stored in the power storage device 46, power can be sold.

  As described above in detail, according to the middle water use management system 1 of the present embodiment, the water levels of the room temperature medium water tank 41 and the warm water tank 42 with respect to the reserved water utilization facility 4 are reserved. Depending on the situation, medium water can be supplied. Further, when the water level in the room temperature medium water tank 41 or the warm water tank 42 decreases, the medium water use facility 4 in the medium water tank is changed according to the priority set for each medium water use facility 4. Can be controlled appropriately. Thus, according to the middle water utilization management system 1 of this embodiment, middle water such as rainwater can be appropriately supplied to the middle water utilization facility 4.

  The embodiment described above is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.
