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 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 simplify the constitution of an energy delivery device, and to attain safety design and operation without any anxiety about dry-out state of a heat exchanger in a heat storage device, by furnishing a delivery device which delivers high temperature water, and converts it into water and steam at a specified temperature and pressure after the pressure of the high temperature water is reduced by a pressure reducing device. CONSTITUTION:When water pressurized to 10atm, for example, by a booster pump 5 is fed into a heat exchanger 3 in a latent heat storage 1 through a water feed pipe 4, the water absorbs the high temperature heat stored in heat storage media, raising its temperature to around 180 deg.C. As the water is pressurized to 10atm, it is usually discharged as high temperature water from a drain 6, avoiding dangerous abrupt expansion in volume in case of evaporation, and dry-out state at the stop of operation as well. When the high temperature water is released in a flash tank 8 through a pressure reducing valve 7, it converts into high temperature steam and boiling water, reaching an equilibrium state under the pressure in the flash tank 8. The steam discharged from a steam pipe 9 can be used as a heat source or a pressure source. The boiling water can be used as hot water at a adequate temperature by introducing water into the flash tank 8 to reduce the water temperature.

摘要： PURPOSE:To perform power generation easily and efficiently by heating and cooling plural pieces of hydrogen storage alloys, emitting and storing hydrogen and, after a gas turbine is driven and a generator is rotated with the emitted hydrogen, occluding the hydrogen again. CONSTITUTION:Each of three-way valves 12, 13 is selected, and a heating medium out of a high heat source heat exchanger 17 is led into a vessel 1 via a line 5, heating a hydrogen storage alloy M1, and thereby hydrogen is emitted. Likewise another heating medium out of a low heat source heat exchanger 18 is led into a vessel 2 through a line 6 and cooling a hydrogen storage alloy M2, the hydrogen is occluded. Then the three-way valves 12, 13 are selected again, and the hydrogen emitted to the vessel 1 and each of lines 8, 9 is led into a gas turbine 3 through a line 4, thereby driving a generator 4. On the other hand, hydrogen out of this gas turbine 3 is led into the vessel 2 via each of lines 15, 11. Afterward, this operation is repeated whereby power generation is executed in succession.
