Explain Hx. FIG. 1 shows the relationship between hydrogen storage capacity (ratio of metal atoms to hydrogen atoms (H/M)) and hydrogen dissociation pressure. As shown in Figure 1, over a relatively wide range of hydrogen storage capacity (H/M), the hydrogen dissociation pressure of TiMn 1.5 -Hx is virtually constant at an equilibrium state, and when a hydrogen pressure higher than this equilibrium pressure is applied, Hydrogen is occluded until a metal hydride with a high hydrogen content is formed. Furthermore, when the pressure inside the container is lowered, hydrogen is released along the equilibrium pressure if the temperature is constant, and the amount of hydrogen stored decreases, and as the hydrogen storage approaches a depleted state, the equilibrium pressure decreases rapidly.

ある。 In this way, the metal hydride undergoes a hydrogen release process by lowering the equilibrium pressure, and an endothermic reaction occurs at this time. The amount of heat absorbed depends on the type of metal hydride.
TiMn 1.5 −Hx is different, but TiMn 1.5 −Hx is about
It has an endothermic amount of 7.0kcal/molH 2 . This cooling device effectively utilizes this amount of heat absorption to enable continuous cooling.

From the temperature and pressure characteristics of metal hydrides MH 1 and MH 2 which have different hydrogen dissociation pressures at the same temperature, first, MH 1 with a low dissociation pressure (point A) is heated, and the storage pressure of MH 2 with a high dissociation pressure (C point) higher (point B). From the pressure difference between points B and C, MH 1 to MH 2
Hydrogen moves to and is occluded from point C. Next, when MH 1 and MH 2 cool, the pressure between them decreases and a pressure difference is formed between points D and A, hydrogen moves from MH 2 to MH 1 , and at point D it is cooled by the endothermic action due to the release of hydrogen. This is how it works. Here, point A: 40℃,

In Figure 3, a certain amount of metal hydride is contained in pressure-resistant metal containers 1, 2, 3, and 4 with built-in heat exchangers.
Put in MH 1 , MH 2 , MH 3 , MH 4 , valve 5,
6 and connecting pipes 7 and 8, so that hydrogen can move through them. A pair of pressure-resistant metal containers 2 and 4 are set as one set, and one of the pressure-resistant metal containers 2 and 4 is attached to a heat-insulating storage wall 9. This pressure-resistant metal container is packing 1
H-shaped structure (container with only larger outer diameter at both ends) to prevent heat transfer between the inside and outside of the refrigerator at 0.11.
The other pressure-resistant metal containers 1 and 3 are each equipped with electric heaters 12 and 13 so that they can be heated. Further, hydrogen was supplied from the valve, and when one of the metal hydrides was occluded, it was all sealed. Then, MH 1 , which is storing hydrogen, is heated,
When hydrogen is released and stored in MH 2 , the pressure-resistant metal container 2 is exposed to the outside of the refrigerator to radiate heat (regeneration process). In this process, hydrogen is absorbed
When MH 3 absorbs hydrogen from MH 4 due to the pressure difference between the two, the pressure-resistant metal container 4 is inserted into the inside of the refrigerator to absorb the heat inside the refrigerator and lower the temperature inside the refrigerator (cooling process).

圧材料としてTiMn1.5合金を各々1.0Kgを入れた。
そして駆動側が効率よく働くために高圧材料を低
圧材料より少なくした。冷却側のTiMn1.5−Hx
の吸蔵量は約7kcal／molH2であるから、理論的
にはTiMn1.5−Hxの利用出来る水素量は1.5W％
とすると、
1.5／2.0ｇ×7kcal／molH2＝5.25kcal／100ｇ
となる。したがつて、１Kg当りの冷却熱量として
52.5kcalが得られることになる。また、温度低下
による水素利用効率、熱損失などを考慮すると実
際に利用出来る熱量は約35kcal程度となる。 To investigate the cooling effect, first, 1.2 kg of CaNi 5 alloy (which absorbs hydrogen and becomes metal hydride) was placed as a low-pressure material in pressure-resistant metal containers MH 1 and MH 3 .
and 1.0 kg each of TiMn 1.5 alloy as a high-pressure material was placed in the other pressure-resistant metal containers MH 2 and MH 4 .
In order to make the drive side work more efficiently, the amount of high-pressure material used was less than that of low-pressure material. TiMn 1.5 −Hx on cooling side
Since the storage capacity of TiMn 1.5 -Hx is approximately 7kcal/ molH2 , theoretically the amount of hydrogen that can be used by TiMn 1.5 -Hx is 1.5W%.
Then, 1.5/2.0g×7kcal/molH 2 =5.25kcal/100g. Therefore, as the amount of cooling heat per 1 kg
You will get 52.5kcal. Furthermore, considering hydrogen utilization efficiency and heat loss due to temperature drop, the actual amount of heat that can be used is about 35 kcal.
今、TiMn1.5−Hxの熱容量、銅製の耐圧容器
の熱容量を計算すると、熱負荷量＝比熱×重量×
温度差より0.11（比熱）×１Kg（重量）＋0.09（比
熱）×0.5Kg（重量）＝0.56kcal／℃となる。また
内容物を仮に水（１）と考えると1.0kcal／℃
の熱負荷量が必要であり、合計すると１℃冷却す
るのに1.56kcalの熱負荷量が必要となる。温度25
℃の庫内を３℃まで冷却することができる。内容
量の40の冷蔵庫を用いる時の連続時冷却負荷は
約13kcal／ｈであるから、２時間に１回のサイク
ルで庫内を約３℃に保持することができる。 Now, when calculating the heat capacity of TiMn 1.5 −Hx and the heat capacity of a copper pressure vessel, the heat load = specific heat x weight x
From the temperature difference, 0.11 (specific heat) x 1 Kg (weight) + 0.09 (specific heat) x 0.5 Kg (weight) = 0.56 kcal/℃. Also, assuming that the content is water (1), it is 1.0kcal/℃
In total, a heat load of 1.56 kcal is required to cool the room by 1°C. temperature 25
The inside of the refrigerator can be cooled down to 3°C. Since the continuous cooling load when using a refrigerator with an internal capacity of 40 is approximately 13 kcal/h, the inside of the refrigerator can be maintained at approximately 3° C. by cycling once every two hours.

We are trying to improve the quality of our products. Each pressure-resistant metal container is connected with telescopic piping, and H
By smoothing the movement of the mold container and the flow of hydrogen, there is a significant effect in making it relatively compact and improving reliability.
This time, it is possible to perform one cycle in two hours to cool and maintain the temperature inside the refrigerator to about 3°C, but it is also possible to perform two cycles in one hour. In this case, the weight of the metal hydride can be reduced to 1/4, leading to a significant reduction in size and weight of the cooler itself.
