However, in the above-described hot spring resource protection and stable supply device, the relay tank and the plurality of hot water storage tanks are provided, and the control device is attached to each of the relay tank and the plurality of hot water storage tanks. There has been a problem that the economic burden of the entire system, such as the burden on the control device itself and the burden on the maintenance, is large.
In addition, the discharge amount of the hot water pump is controlled so that the water level of the relay tank is always full, and the rotation speed of the hot water pump is controlled so that the water level of the hot water tank is always full. When the total amount of hot springs used at many facilities that vary greatly depending on the time of day is at a peak (for example, from evening to night), pumps should always be in a high output state in order to increase the amount of hot water distributed according to the total amount used. In addition to having to operate, it is necessary to use a pump with a relatively large capacity corresponding to the total amount of hot springs used during peak hours.

  Therefore, the present invention not only makes it possible to solve the above-mentioned difficulties, but also protects hot spring resources without wasting them, enables efficient management, helps save energy, and makes stable hot springs. Supply, ideal hot spring management, pump consumption can be suppressed, pumps with relatively small capacity can be used, and the structure is simple and maintenance is easy.

In the period up to the level arrival time zone, set a gradual release assumption line so that the amount of hot water stored in the hot water storage tank C gradually decreases from the maximum hot water storage level to the minimum hot water storage level. From the time until the maximum hot water storage level arrival time, a mild stockpiling assumption line is established so that the hot spring water storage capacity in hot water tank C gradually increases from the minimum hot water level to the maximum hot water storage level. And, a hot water storage amount of the hot springs in the hot water tank C, employing a means be configured to be controlled by the central monitoring and control unit so as to follow the stockpile assuming line and the discharge assumed line.

  Moreover, in the hot spring supply management system according to claim 2, the expected release line is set so as to match the total amount of hot spring usage for each applicable time zone at the plurality of usage facilities F1, F2, F3, and F4. Adopted means.

Since it is configured to be controlled by the central monitoring and control device along the line, the total amount of hot springs used at many use facilities F1, F2, F3, and F4 that vary greatly depending on the time of day is at the peak or around the peak (for example, in the evening Even during the night), there is no need to greatly increase the amount of hot water in the source facilities A1, A2, A3 according to the total amount of use, and it is not necessary to operate the pumps at a high output state at all times. Because there is no need for a pump with a relatively large capacity corresponding to the total amount of hot springs used at peak hours, a pump with a relatively small capacity can be used, which reduces power consumption and equipment load. It will need as, a very economical hot spring supply management systems.
In addition, since it is not necessary to always operate the pumps in a high output state, consumption thereof can be suppressed.

And the maximum hot water storage level of the hot spring in the hot water storage tank C, the minimum hot water storage level, the maximum hot water storage level arrival time zone in a day, and the minimum hot water storage level arrival time zone are set.
By the way, it is desirable that the maximum hot water storage level is set, for example, below the overflow line of the hot water tank C, and the minimum hot water storage level is, for example, a position where at least about 30 percent of hot springs remain in the lower part of the hot water tank C. It is desirable to set it higher. That is, the maximum hot water storage level is set with a slight margin with respect to the overflow line of the hot water tank C, and consideration is given so that the hot spring is not wasted when the level is exceeded. It is set with a considerable margin for the hot springs remaining in the house, and it is considered so that even if a problem occurs when the level is exceeded, there will be no hindrance to the supply of hot springs.

  Then, the minimum hot water storage level arrival time zone is set around or after the peak time when the hot spring usage is highest in the plurality of use facilities F1, F2, F3, F4, while the maximum hot water storage level arrival time zone Is set around the non-peak hours or after the non-peak hours when the amount of hot spring usage at the plurality of use facilities F1, F2, F3, and F4 is the smallest.
