Description

  The present invention relates to a hot spring heating apparatus that uses a surplus hot spring among hot springs supplied from a hot spring supply piping network.

  Generally, as a heater for heating an indoor space, there are an air conditioner such as an air conditioner, an electric heater, an oil heater, a steam heater, and the like, which are practically used in various places. These various heaters convert electricity, oil, heavy oil into heat energy and use this as a heat source to heat the room to raise the room temperature.

  On the other hand, in hot spring areas, a heater utilizing hot spring heat is proposed by Utility Model Registration No. 3171711. The heater according to the present invention is configured so that hot spring water drained without being used is radiated through a radiator installed indoors by piping.

  For example, since an electric stove uses electric energy, electric power of 0.5 to 1.2 kw / h is consumed during use. For this reason, an electric charge of several tens of yen per hour is required. In addition, since the air conditioner uses heat generated when cooling the refrigerant for heating, the conversion efficiency is low, and thus large power is consumed. Furthermore, a heater that burns fuel such as petroleum to generate thermal energy requires a fuel cost to consume the fuel.

  On the other hand, since the heater shown in Patent Document 1 uses hot spring heat and does not use electric energy or fossil fuel, the heating cost is greatly reduced and the temperature of the heat generating portion is low. Therefore, it is possible to eliminate the risk of burns to the user or the risk of fire that burns down the house. However, in the heater shown in Patent Document 1, since the hot spring water that is drained without being used is used, when the hot spring water is used for its original purpose, the heating function is lost and the heating is performed. There is a problem that cannot be used as a machine.

  The problem to be solved by the present invention is that the overflow of the hot spring water supplied from the hot spring supply piping network and stored in the heat retaining tank is stored in the drain tank, so that it can be heated for a predetermined time even when it does not overflow. It is to provide a hot spring heating device.

  A hot spring heating apparatus according to the present invention stores a hot spring water having a predetermined temperature supplied from a hot spring supply piping network, and has a heat retaining tank including a drain pipe for draining the drain hot spring water for an overflow exceeding a predetermined storage amount, and A drain tank for storing drain hot spring water in a heat-retaining state, a radiator embedded in the drain hot spring water in the drain tank, a heat exchanger for heating indoors and the like, and the radiator through a pipe And a heat transfer fluid that circulates between the heat exchanger and the heat transfer fluid heated by the radiator in the drain tank is radiated from the heat exchanger and heated.

  Moreover, you may mix the antifreezing liquid for antifreezing as a heat transfer fluid which circulates between the inside of a radiator and a heat exchanger.

  Furthermore, the heat transfer fluid that circulates between the radiator and the heat exchanger may be air.

  According to the present invention, since the drain hot spring water overflowing from the heat retaining tank is stored in the drain tank in a warm state, even if the drain hot spring water does not flow out for a predetermined time, the radiator embedded in the drain tank is used. Since the heat transfer fluid can be heated, indoors can be continuously heated. Furthermore, since the overflowing hot spring water that is originally discarded is used as the heat source, the cost required for the heat source can be substantially eliminated. In addition, since hot spring water is used as a heat source, exhaust gas such as carbon dioxide generated when burning petroleum fuel is not generated, and clean heating can be realized, so that it is possible to prevent the environment from being destroyed. . Furthermore, since the temperature of the hot spring that overflows is about 60 ° C., it is possible to avoid risk factors such as burns or fire of the user.

  Moreover, antifreezing liquid for freezing prevention is mixed with the heat transfer fluid that circulates between the radiator and the heat exchanger, thereby preventing freezing of heat transfer fluid such as water in a cold region. be able to.

  Furthermore, if the heat transfer fluid that circulates between the radiator and the heat exchanger is air, the possibility that the radiator embedded in the drain tank and the heat exchanger installed indoors will be corroded by the heat transfer fluid is eliminated. In addition, even when the radiator, the heat exchanger, and the pipe are damaged, the heat transfer fluid outflow accident is prevented. Air has low heat storage efficiency and cannot raise the room temperature in a short time, but it can be heated at a comfortable room temperature without a sudden temperature increase by continuous operation for a long time.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a hot spring heating apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a hot spring supply piping network, and hot water having a predetermined temperature is supplied from the piping network 1 to a heat retaining tank 2 through a supply pipe 1a. The hot spring supply piping network 1 is a system that supplies hot spring water that has springed out from a hot water source, which is a source hot spring, to a user's home or company by piping in an area where hot spring water springs out. In a user's home or the like, for example, a heat retaining tank 2 having a storage amount of 500 liters is installed, and the hot spring supplied to the heat retaining tank 2 is stored. The heat retaining tank 2 is a heat retaining type like a thermos, and is configured to keep the supplied hot spring water at a predetermined temperature at a constant temperature. The heat retaining tank 2 is usually installed outdoors, and is piped to an indoor bath, a washroom, a kitchen or the like by a delivery pipe 4 connected to the lower part of the heat retaining tank 2. In the hot spring supply piping network 1, for example, about 0.35 liters of hot spring water per minute is always supplied to the heat retaining tank 2, and the daily supply amount is about 500 liters. This is to prevent cooling of the hot spring water in the piping that occurs when the outflow of hot spring water is stopped.

  Since the hot spring water having a predetermined temperature supplied to the heat retaining tank 2 is used for various purposes in each home and the like, the storage amount in the heat retaining tank 2 changes with time. When the amount of hot spring water used is small or not used, the supply amount exceeds the amount used, so the amount stored in the heat retaining tank 2 increases and eventually the overflow from the drain pipe 3 connected to the upper part of the heat retaining tank 2 Of hot spring water flows out. Incidentally, the temperature of the hot spring water supplied from the hot spring supply piping network 1 to the heat retaining tank 2 is about 50 to 70 degrees Celsius, and the hot spring water at this temperature flows out from the drain pipe 3.

  The drain pipe 3 is connected to the inlet 5 a of the drain tank 5. The drain tank 5 is of a heat retaining type, similar to the heat retaining tank 2, and is configured to keep the temperature of the supplied hot spring water at a constant temperature. In addition, a discharge port 5b is provided in the upper part of the drain tank 5 so that the overflowing hot spring water flows out into a drainage ditch or the like. The inflow port 5 a of the drain tank 5 is provided at the lower part so that the overflowing hot spring water flows from the lower part of the drain tank 5. Thereby, the temperature distribution of the hot spring water in the drain tank 5 can be made substantially uniform vertically.

  A radiator 6 is installed in the drain tank 5 so as to be immersed in hot spring water. As the radiator 6, a well-known radiator such as a vehicle or an air conditioner as shown in FIG. 2 can be used. Although the radiator 6 has a well-known configuration and detailed description is omitted, a tube 6a serving as a passage for a heat transfer fluid, which will be described later, and a fin for receiving heat from the hot spring water and transferring heat to the tube 6a. 6b. Furthermore, the radiator 6 is provided with an inflow port 6c and a drain port 6d.

  As the radiator, a radiator 12 in which a pipe is spirally wound as shown in FIG. 3 may be used in addition to the vehicle or air conditioner shown in FIG. The spiral radiator 12 is formed of, for example, a rust-resistant metal pipe such as copper or stainless steel. The radiator 12 is also provided with an inlet 12a and a drain port 12b.

  An inlet 6c and a drain port 6d of the radiator 6 are connected to a heat exchanger 8 installed indoors or the like via a pipe 7, and a heat transfer fluid is circulated between the radiator 6 and the heat exchanger 8. Yes. A pump 11 is installed in the middle of the pipe 7 so that the heat transfer fluid circulates between the radiator 6 and the heat exchanger 8. The heat exchanger 8 installed indoors or the like can use a hot water room heater and a fan coil unit provided with a generally used blower fan. In addition, you may use the panel heater 9 which distribute | circulates warm water as shown in FIG. 4, and the pipe radiator 10 as shown in FIG. The panel heater 9 is provided with an inflow port 9 a and a drain port 9 b and is connected to the pipe 7. The pipe radiator 10 is also provided with an inflow port 10a and a drain port 10b, and is similarly connected to the pipe 7.

  As the heat transfer fluid, general water or oil can be used. When water is used, in a cold region, when the hot spring heating device is stopped in winter, the water in the pipe 7 is frozen and becomes unusable. When the heat transfer fluid is air, such an accident can be prevented.

  Next, the operation of the hot spring heating apparatus according to the present invention will be described. From the pipe network 1, hot spring water having a predetermined temperature is supplied to the heat retaining tank 2 through the supply pipe 1a. When the hot spring water exceeds a predetermined capacity of the heat insulation tank 2, overflow of the hot spring water flows out from the drain pipe 3 at the top of the heat insulation tank 2. The drain pipe 3 and the inflow port 5a of the drain tank 5 are connected, and the drain tank 5 stores hot spring water for the overflow. Since the drain tank 5 is a heat retaining type, the temperature of the hot spring water for the overflow is maintained. When the drain tank 5 is filled with the overflowing hot spring water, the overflow hot spring water flows out from the discharge port 5 b provided at the upper part of the drain tank 5. For this reason, since the inflow and outflow of hot spring water are repeated in the drain tank 5, the internal hot spring water is maintained at a substantially constant temperature.

  Since the radiator 6 is immersed in the hot spring water for the overflow filled in the drain tank 5, the heat transfer fluid that circulates inside is heated by the radiator 6. This heat transfer fluid is sent to a heat exchanger 8 installed indoors by a pump 11, and heating is performed by discharging warm air into the room. The heat transfer fluid whose temperature has been lowered by the heat exchanger 8 is sent again to the radiator 6, heated by the hot spring water for the overflow amount, and then sent to the heat exchanger 8. In this manner, indoors or the like can be heated by circulating the heat transfer fluid between the radiator 6 and the heat exchanger 8.

  On the other hand, when hot spring water stored in the heat retaining tank 2 is used in a bath, a washroom, a kitchen, or the like, the hot spring water for the overflow is stopped. In this case, since the hot water for the overflow is stored in the drain tank 5 in a heat-retaining state, the indoor heating or the like is continued by circulating the heat transfer fluid between the radiator 6 and the heat exchanger 8. The However, when the inflow of hot spring water corresponding to the overflow into the drain tank 5 is stopped for a long time, the temperature of the hot spring water in the drain tank 5 gradually decreases. During this time, if the room has a heat insulating structure, there is no rapid drop in room temperature. Since the hot spring water is supplied to the thermal insulation tank 2 from the hot spring supply piping network 1, the hot spring water is stored in the thermal insulation tank 2 after a while, and the overflow hot spring water drains from the drain pipe 3 of the thermal insulation tank 2 before long. It will flow into the tank 5, and the heating function mentioned above will return again.

  Although the present invention has been specifically described based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. In the embodiment described above, the interior is heated, but the drying chamber may be heated to dry clothes and the like. When applied to this drying room, it can be used throughout the year, not only in winter. Further, the heat exchanger installed indoors may be a floor heating device installed inside the floor, and heat transfer fluid may be circulated through the floor heating device.
