[Industrial applications]

 The present invention has heretofore been considered to be inadequate unless the temperature is about 60 ° C or higher, and it is possible to use circulating water for floor heating at a low temperature of around 40 ° C. The present invention relates to a multi-purpose low-temperature water circulation facility that uses circulating water not only as floor heating but also as bath water for bathtubs.

[0002]

[Prior art]

 Floor heating is an optimal heating method that achieves the ideal heating with foot heating and head cooling, and is also optimal for the lifestyle of Japanese living in low places. However, in the conventional floor heating method, first, waste concrete is cast, a heat radiation pipe is stretched over it, and fixed with 50-100 mm cinder concrete. Finished mortar is struck and floor material is stretched. Therefore, the heat transmission coefficient is low, and the temperature of the hot water for the heat medium passing through the inside of the heat dissipation tube is as high as 60 to 80 ° C. Therefore, the energy consumption of heat sources such as boilers and hot water generators that produce high-temperature water is high, and running costs are extremely high. In addition, the hot water supply pipelines are often one-route pipelines or simple route divisions such as floors. As the temperature rises, the difference in temperature of hot water also increases, causing unevenness in room temperature, causing the phenomenon of being hot enough to dry up to the back of your throat and cold enough to require auxiliary heating. It is generally accepted that floor heating is not suitable for the ground.

[0003]

[Problems to be solved by the device]

 In order to revise the high-temperature water circulation, which is the reason why conventional floor heating has not spread as ideal heating, the present invention reduces the difference in temperature between the hot water supplied to the floor and the floor heat radiation structure with good heat transmission coefficient. We have developed a floor heating system that uses low-temperature water 40 ° C before and after the temperature of the same building in the same building. It is intended to develop a multi-purpose low-temperature water circulation system that has the functions of filtering, sterilizing, and activating water so that it can be used for bathtubs that require hot water of the same type, and can use floor heating and bathtubs with the same hot water. is there.

[0004]

[Means for Solving the Problems]

 First, in order to enable floor heating by circulating low-temperature water, heat-insulating material 31 is laid on the discarded concrete portion 30, and heat-dissipating panels 28 are laid out according to the required area. A hot water circulation pipe line 13 with a circulation pump 23 is constructed from the heat source 1, and a hot water supply pipe line 5, a hot water outflow header 2 and a hot water return pipe line are provided for each room and space load system for floor heating. The passage 12 and the hot water return header 3 are provided, and the total number of the divided heat radiation panels 28 is further divided into a certain number in each hot water outgoing header 2, and the hot water supply pipeline 6 for each load is provided. Further, the individual hot water supply pipeline 7 for each panel 28 is branched from the hot water supply pipeline 6 for each load, and similarly in the hot water return pipeline, the hot water return pipeline 11 for each load is also used for the individual hot water return pipeline. 10 The individual hot water supply pipe 7 is connected to the hot water inlet 8 of each panel 28, and the individual hot water return pipe 10 is connected to the hot water outlet 9 of each panel 28. The temperature of the hot water supplied by the room is changed by the hot water supplied to the room, and the hot water that has passed through one heat dissipation part 29 immediately returns to the hot water return conduit without passing through the other panel 28. By preventing the difference, floor heating can be sufficiently performed even with low-temperature water around 40 ° C, and individual room temperature adjustment can be easily performed. Next, in order to provide a low-temperature water circulation system for floor heating and a bathtub, a hot water outlet pipe 14 is provided from the heat source 1 to the hot water intake port 16 of the bathtub 15, and a heat source is supplied from the hot water suction port 17 of the bathtub 15. 1, a hot water return conduit 18 is provided, the warm water return conduit 18 is connected to the hot water circulation conduit 13 for floor heating described above, and the conduit 13 is provided with a valve 19, a filter 20, a sterilizer 21, It is configured to include a water heater 22.

[0005]

[Action]

 When the equipment according to the present invention according to claim 2 is first started up, the pipes 13, 14, 18 are filled with water, the circulation pump 23 and the circulation pump 4 are operated, and the heat source 1 is circulated throughout the equipment. Is heated up to around 40 ° C. The hot water that has reached an appropriate temperature of about 40 ° C. passes through the bathtub 15, the filter 20, the sterilizer 21, and the water activating device 22 to be activated by filtration and sterilization. The circulation pump 4 provided separately flows through the hot water outflow header 2 into the individual panels 28 laid in each room or space, radiates the heat through the heat radiating section 29, and then returns to the hot water return header 3 and the pipeline. Follow the route of returning to the heat source 1 through the hot water return conduit side of 13 and heating the temperature decrease. Therefore, in the bathtub, purified and activated water having a constant temperature can always be used, and in a room or space where floor heating is performed, desired room temperature can be heated. Further, valves 26 and 27 are provided in front of the floor heating portion of the hot water circulation line 13, and further, a valve 25 is provided in front of these valves to bypass the hot water return line side to the hot water return line side. Since the pipe line 24 is provided, during the period when heating is not required, the valves 26 and 27 are closed, the floor heating pipe line is stopped, and the valve 25 is opened to bypass the bypass pipe line 24. It can also be used as a hot water circulation system.

[Effect of device]

 According to this plan, floor heating, which was generally considered to be insufficient unless high-temperature water of 60 to 80 ° C, can be sufficiently heated even with low-temperature water of around 40 ° C. As a result, running costs can be significantly reduced. In addition, since the two-stage pipeline structure is used, one for each load system using a hot water header and one for each panel, there is no room temperature mudling due to the difference in temperature of the supplied hot water, and auxiliary heating is eliminated. Since it becomes unnecessary and the desired room temperature can be set individually, it is possible to create a very comfortable and ideal heating environment. In recent years, there has been a growing need for bathroom equipment that can be bathed anytime, called a 24-hour bath, and that does not require refilling or cleaning of water. According to this plan, the circulating hot water temperature for floor heating is 40 ° C. Since it is before and after and is suitable for bath water temperature of bathtub, it is possible to construct a multipurpose low temperature water circulation system that combines floor heating and bath water circulation system. You can take a bath at any time, and you can create a comfortable environment where the room is always heated and heated appropriately. During the period when heating is not required, the floor heating pipeline can be suspended and only the bathtub bath water circulation pipeline can be used.
