More specifically, the present invention relates to a method of operating a heat pump device using metal hydrides.

られており、近年、これら金属水素化物の特性を
利用したヒートポンプ装置が提案されている。 It is known that certain metals and alloys exothermically absorb hydrogen to form metal hydroxides, and that these metal hydrides reversibly and endothermically release hydrogen. Examples of such metal hydrides include lanthanum-nickel hydride (LaNi 5 Hx), calcium-nickel hydride (CaNi 5 Hx), Mitsushi metal nickel hydride (Mmi 5 Hx), and iron-titanium hydride (FeTiHx). , magnesium-nickel hydride (Mg 2 NiHx), etc., and in recent years, heat pump devices utilizing the properties of these metal hydrides have been proposed.

する傾向がある。 In conventional heat pump devices, metal hydride is often filled in a sealed container as a heat exchanger to absorb and release hydrogen.
Generally, when a metal hydride absorbs hydrogen, its volume expands. Therefore, conventional heat exchangers take into account the equilibrium decomposition pressure of the metal hydride under operating conditions, as well as the mechanical stress associated with the volume expansion of the metal hydride as described above, so that deformation and damage do not occur. It is designed to. As a result, the heat exchanger has a large weight per unit charge of metal hydride, that is, a large heat capacity, and requires, for example, a large amount of driving thermal energy, or has a small output, resulting in a small coefficient of performance of the device. Additionally, metal hydrides generally tend to become finely powdered during the process of repeatedly absorbing and desorbing hydrogen, making it difficult for hydrogen to circulate.
本発明は上記に鑑みてなされたものであつて、
金属水素化物の水素の吸蔵に伴う体積膨張を考慮

提供することを目的とする。 The present invention has been made in view of the above, and includes:
There is virtually no need to consider the volumetric expansion of metal hydrides due to hydrogen absorption, and therefore the coefficient of performance can be calculated using a heat exchanger that only needs to withstand the equilibrium decomposition pressure of metal hydrides under the operating conditions. It is an object of the present invention to provide a method for operating a heat pump device, which allows hydrogen to be absorbed and released from a metal hydride smoothly and quickly by ensuring a hydrogen flow path in a heat exchanger.

ある。 The method of operating a heat pump device of the present invention includes a closed container divided into two chambers, and a porous body that is permeable to hydrogen and has elasticity, and extends between the two chambers to allow hydrogen to pass between these chambers. , has a hydrogen passage through which metal hydride does not flow, and first and second metal hydrides filled in the two chambers, respectively, and heats the first metal hydride to release hydrogen; introducing hydrogen into the hydrogen passage to exothermically occlude hydrogen in the second metal hydride, then cooling the first metal hydride and causing the second metal hydride to endothermically release hydrogen; This hydrogen is introduced into the hydrogen passage and is exothermically occluded by the first metal hydride.

It will be done. The shape of the porous body is not particularly limited, but it is usually cylindrical, cylindrical, prismatic, or prismatic so that it is inserted in the axial direction of the container and contracts uniformly in response to the volume expansion of the metal hydride. It is formed into a rod shape such as.

遮断材を装着し、この遮断材の両側に多孔体を接
続する。遮断材は弾力性を有さなくともよい。 The porous body, like a polytetrafluoroethylene sintered body, is preferably permeable to hydrogen but not permeable to metal hydrides. In this case, the perforated plate forms a hydrogen passage that penetrates the partition wall and directly connects the two chambers. On the other hand, when using a porous material such as glass fiber mat that permeates hydrogen as well as metal hydride, metal hydride that does not permeate metal hydride, such as a metal sintered body, is used in the through-holes of the partition wall. A blocking material is installed, and porous bodies are connected to both sides of this blocking material. The blocking material does not need to have elasticity.

加わらず、又は軽減されて加わるので、容器の変
形や破損のおそれがない。 In the heat pump device used in the present invention, the metal hydride is filled in the void between the inner wall of the container and the porous body, so even if the metal hydride expands when absorbing hydrogen, the porous body contracts accordingly. Therefore, the mechanical stress due to the expansion of the metal hydride is absorbed by the porous body. As a result, the stress is not applied to the container or is applied in a reduced manner, so there is no risk of deformation or damage to the container.
