摘要： PURPOSE:To provide a heat storage tank which yields a high heat storage efficiency by employing a length of a flexible tube that opens in the upper part of a high- temperature side water tank and suspending the open end of it at a certain distance from the water surface in the water body by means of a float that floats on the water surface in the water tank so as to stabilize the water flow. CONSTITUTION:A flexible tube 8 has at its open end a ring 10 which is suspended from a float 11 by a suspension rope 12. As cold water supplied through a pipe 16 is fed to the bottom of a water tank 2a, it replaces lukewarm water. When the boundary between cold water and lukewarm water rises as high as the level of the open end ring 10 of the tube 6, the cold water flows into the lower layer in a water tank 2b. The replacement of lukewarm water by cold water takes place between the upper and lower layers in a water tank and between the water tanks, and the water temperature becomes highest at the upper layer of the final water tank 2h. The distance (d) of the open end of the tubes 17, 6 from the water surface is constant regardless of the water level. Therefore, the velocity (v) of water flowing out never exceeds a predetermined value. Thus, the water flow can steadily be controlled to improve the heat storage efficiency.

摘要： PURPOSE:To obtain a heat accumulator which can be switched from/to the giving-off of heat to/from the taking-in of heat simply and clearly with high utilization efficiency of the accumulated heat, by a structure wherein two opening parts, which respectively open to the upper layer and the lower layer of a tank, are provided at ends of each circuit pipe, which connects to a primary and a secondary heat exchanger systems and only one of either the opening part at the upper layer or the opening part at the lower layer is open and by the different combination of the upper layer and lower layer between pipes belonging to different tanks. CONSTITUTION:When space is cooled in summer season, the water 21 in a heat accumulator is cooled down during the night by means of the refrigerator of a primary heat exchanger 5 and, after that, supplied through a circuit pipe 8 to a tank 2-1. At the end of the circuit pipe 8, an opening part 11 at the lower layer of the tank 2-1 is open so as to feed cold water into the lower layer of the tank 2-1 in order to accumulate from below and then to flow into a tank 2-2 through a communicating pipe 3. Concretely, the cold water in the upper layer of the tank 2-1 is sent in the lower layer of the tank 2-2, by opening upper layer opening part 10 on the tank 2-1 side, while a lower layer opening part 11 on the tank 2-2 side. By repeating the flow of cold water as just described above, cold water is accumulated in tank 2-1-2-4. The accumulated cold water is supplied to an air conditioner acting as a secondary heat exchanger 7 with a secondary pump 6 by being sucked up through a secondary circuit pipe 9 from the lower layer opening part 11 of the tank 2-1 at the air conditioning operation during the day. When space is heated in winter season, the opening and closing of opening parts at upper layer 10 and of those at lower layer 11 are reversed.

摘要： PURPOSE:To restrict the outflow rate and inflow rate of water flowing between water tanks to be not higher than a predetermined value and favorably form isothermal layers, by a construction wherein an upper communicating pipe is provided horizontally at a position of partition walls partitioning each water tank in a connected multi-tank system, and a lower communicating pipe at a bottom surface of the water tank is disposed horizontally. CONSTITUTION:The upper communicating pipe 6 and the lower communicating tank 7 are provided at each partition wall 5. The pipe 6 is located so that water surface comes to an upper end part thereof when the water tank is filled up with water (at normal time), while the pipe 67 is so disposed in the manner that the lower end thereof comes into contact with the bottom surface of the tank, and functions also as a drain pipe. Lukewarm water fed into a return tank 2 flows into the adjacent water tank 3 by passing through the pipe 6, and in addition, generates a water flow passing through the pipe 7. A vertical water flow is induced in the water tank due to the difference in water flow rate, a similar flow is generated also in the adjacent water tanks, and cold water is sequentially replaced by lukewarm water.

摘要： PURPOSE:To cast a steel pipe sheet pile which is shaped like a bottomed vessel and used as a water tank pipe in simple structure and economically. CONSTITUTION:Generally, steel pipe sheet piles are considered as a left-in-place material. However, to make the best use of the steel sheet pile as a water tank, such as a heat storage tank, a vessel-like sheet pile whose lower end is closed is formed. When this steel pipe sheet pile 1a is cast into an excavated hole 6, a stabilizer liquid 8 is filled up in the excavated hole 6. While the stabilizer liquid 8 is being injected into a steel pipe 2, natural settlement takes place with the self weight of the steel pipe sheet pile 1 and the weight of the injected stabilizer liquid 8, canceling the buoyancy. After the settlement is over, mortar 12 or the like is filled up between the excavated hole 6 and the steel pipe sheet pile 1.

摘要： PURPOSE:To simplify a piping system by providing a thermal stratification type heat accumulator with two headers each of which has an upper and lower openings and providing those headers with a flow-in pipe and flow-out pipe which are connected respectively to a primary and secondary heat exchangers and conducting temperature regulation for winter or summer only by operating the openings. CONSTITUTION:In winter an opening 12 at the lower end of a header 13 and an opening 11 at the upper end of a header 14 are opened. High temperature water heated by a primary heat exchanger passes through a flow-in pipe 17 and flows from the opening 11 of the header 14 to the upper layer section of a water tank 1 and high temperature water in the upper layer section is supplied to a secondary heat exchanger through the opening 11, header 4 and flow-out pipe 18. Low temperature water from the secondary heat exchanger flows to the lower layer section of the tank 1 through the flow-in pipe 16, header 13 and opening 12. The low temperature water in the lower layer is header 13, and a flow-out pipe 15. In summer the same operation is performed with opening that is contrary to what described above. In other words only opening and closing of the upper end openings and lower end openings of the headers can deal with both winter and summer operations, simplifying the piping and operation.
