摘要： PURPOSE:To make it possible to transfer heat horizontally and both horizontally and vertically without the application of a pump, by using a liquid which is turned into vapor phase when it receives heat at an endothermic section as a heat medium, and turned into liquid phase when it radiates heat at a heat radiation section in a closed-loop heat medium circulation passage where a heat medium is circulating inside, and placing the heat radiation section at a position relatively higher than the endothermic section. CONSTITUTION:Two liquid levels A and B of each heat medium fluid are produced within the range of an endothermic section 5 and a heat radiation section 7 during operation. The differential liquid level forces the heat medium fluid to flow from the heat radiation section 7 to the endothermic section 5. The endothermic action to the heat medium at the endothermic section 5 is mostly carried out at a liquid phase section. The heat medium fluid which has absorbed heat is vaporized and flows to the heat radiation section 7. The heat medium vapor is radiated and liquefied at the heat radiation section 7. When the opening of a control valve 10 is adjusted so as to comply with the requirements in terms of the quantity of intake heat energy or temperature, the liquid level of the heat medium is adjusted at the endothermic section 5 within the range from A and A', which makes it possible to take out a specified heat as a result. Moreover, the heat medium can circulate in a stabilized manner within a circulation passage 6.

摘要： PURPOSE:To keep the pressurizing force developed when part of a thermal storage material melts and expands from reaching construction members and promote the heat convection as a whole and improve heat transfer effects by heating the thermal storage material which reaches near the upper surface of the thermal storage material from the lower section of a space in a shell. CONSTITUTION:One or a plurality of subheaters 10 are provided which extend from the bottom section to near the upper surface between the tubes 2 installed in the space in a shell 1. This subheater 10 is provided with a wiring by which the subheater 10 is energized before a main heater 8 is energized or at the same time as it is energized. The upper section of the subheater 10 preferably projects somewhat on the upper face of the thermal storage material 7. Accordingly in thermal storage mode, while the main heater 8 is generating heat, the thermal storage material that melts and expands is pushed up to the upper surface of the thermal storage material 7 to let the pressure escape and the convection of the whole is promoted and the time of whole melting is shortened, because a flow channel has been formed from the lower side to the upper side of the thermal storage material by the heat generation of the subheater 10. By the way it is possible to use a heat-exchange coil through the inside of which a fluid with heat passes in place of the electric heater.

摘要： PURPOSE:To make it possible to use a low temperature heat medium, such as water as a high temperature heat medium, by connecting a high pressure holder to which non-condensable gas is sealed to a flow passage where high temperature fluid is flowing, and applying pressure to the liquid flowing in the passage. CONSTITUTION:An accumulation tank 1 is provided with a heat exchanger section 3 which transmits the heat accumulated in an accusation member 2 inside the accumulation tank to a heat medium inside, and a closed-shaped circulation passage 5 for heat medium including a heat exchanger section 4 which exchanges heat between a fluid to be used by heating and a heat medium. At the top of the ring-shaped passage 5 is connected a high pressure holder 6 to which none-condenced gas, such as nitrogen gas is sealed. A safety valve 7 is connected to this high pressure holder 6. It is desirable that all parts excluding the heat exchanger 4 between the accumulator 1 in the ring-shaped passage and the fluid to be used should be coated with insulation 8. On the way of the ring-shaped passage 5 installed is a pump which drives the heat medium if required. If a pressure which exceeds the pressure required to maintain the liquid phase is applied to the pressure prevailing in the ring-shaped passage, the vaporization in that part can be inhibited. At the same time, the damage to the system can be prevented as well.

摘要： PURPOSE:To raise the heat transfer efficiency without developing unnecessary stresses to a tube and shell by providing fins lined longitudinally in the up-and-down direction in the outer face of each tube and constituting the fines provided on the upper side of the tube in the highest stage so as to make the upper brims of those fins reach near the upper surface of a latent heat storage material at least when it solidifies. CONSTITUTION:In the inside of a cylindrical shell 1 a plurality of tubes 2 are arranged, and in the tube 2 a heat medium fluid flows through to give external heat to a latent heat storage material 3 and plays the role to take out the heat stored in the latent heat storage material to the outside. At the upper and lower sections of the tube 2 a longitudinally running fin 5 s provided in the vertical plane passing through the center of the tube 2, and the fine is formed as one body with the tube 2 by the forming methods such as drawing, extrusion, welding, mechanical joining, etc. and the end brims that are mutually opposite are vertically connected. As a result, the thermal storage material near the tube 2 and fin 5 transfers the heat of the heat medium excellently during thermal storage mode, and a liquefying section penetrating the shell in the up-and-down direction is formed, and heat convection occurs with a raised heat transfer efficiency. Furthermore, in heat radiation mode a solid plate-shaped section of a thermal storage material extending up-and-down in the shell is formed on the contrary so that the mechanical strength is raised and damage is prevented.

摘要： PURPOSE:To efficiently retrieve heat by providing a means which sprays water near to the bottom of the heating medium storage section in a closed container which contains a heat storage material and a heating medium, and a steam delivery pipe which delivers steam collecting in the top of the container. CONSTITUTION:When a heater 4 generates heat by using the nighttime power, etc., the heating medium 3 heats the heat storage material 2 which heats and liquefies the latent heat storage material in it to store the heat in the form of latent heat. In order to use steam, the stop valve 7 in the feed water pipe 6 is opened to supply water to the water ejection pipe 5 under the tap water supply pressure so that water may be ejected into the heating medium from the nozzle 5a as mist. As the heating medium and water do not mix with each other, water is enveloped by the heating medium, and the heat exchange takes place at their boundary surfaces. And so, water is heated higher than 100 deg.C and vaporize into steam which rises through the heating medium 3 as bubbles and collects in the upper part of the storage tank 1. The steam is delivered as low pressure steam from the steam delivery pipe 8 to be used as a heat source, etc.

摘要： PURPOSE:To safely retrieve heat as hot water or steam by incorporating a check valve and a safety valve in the line between the main valve disposed in the fluid supply pipe to the heat exchanger and a cock disposed in the fluid discharge pipe, and providing a bypass pipe which has a stop valve in its way and is connected at its one end to the line ahead of the main valve or behind the cock. CONSTITUTION:The main valve 7 is disposed in the feed water pipe 5 to the heat exchanging section 4, and a cock 8 is disposed in the hot water discharge pipe 6. A safety valve 10 is provided between a check valve 9 disposed on the downstream side of the main valve 7 and said cock 8, and a bypass pipe 11 which is connected to the downstream of the cock 8 at one end has a stop valve 12. Under the normal operating condition, the main valve 7 and cock 8 stay open, and the bypass valve 11 is closed. When water runs at the specified speed through the heat exchanging section 4 of the heating device 2, it receives heat from the heat storage material to become hot water, which is delivered from the hot water discharge pipe 6 at a constant temperature. By changing the opening of the valve to change the flow speed in the heat exchanging section, the temperature of hot water can be changed. Further, by throttling the main valve 7 and opening the cock 8 wide, steam can be delivered at any desired temperature.

摘要： PURPOSE:To allow a continuous delivery of liquid at a desired temperature by providing a means which adjusts the mixing ratio between a high temperature liquid from a heat storage means containing high pressure non-condensible gas and a low temperature liquid, and a control means thereof. CONSTITUTION:The water 5 in a heat storage container 1 is heated by a heater 6, and stores the nighttime power energy, etc., as sensible heat. In order to use hot water at a desired temperature, the valve 11 of the hot water delivery pipe 10 is opened to allow the boiling water in the heat storage container 1 to enter a mixing tank 7 via the boiling water delivery pipe 4 on account of the pressure of non-condensible nitrogen gas 2 or steam. Meanwhile, water at normal temperature enters the mixing tank 7 via feed water pipes 3, 8 and a flow rate regulating valve 9, where it is mixed with the former and the resultant hot water is delivered from the hot water delivery pipe 10. Since the flow rate regulating valve 9 is controlled by a controller 12 in accordance with the difference between the actual temperature of the hot water in the mixing tank 7 and the set temperature, the hot water at a desired temperature can be stably delivered regardless of the delivery rate of hot water or the temperature of the boiling water from the heat storage container.
